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. After the surface cleaning device is parked at the base station, dust, debris and other garbage collected in the dust collecting part of the surface cleaning device is sucked to the base station so as to realize the emptying of the dust collecting part of the surface cleaning device, and/or the charging of the surface cleaning device, and/or the cleaning of the mopping piece of the surface cleaning device, and/or the supplementing of the cleaning liquid accommodating part of the surface cleaning device with cleaning liquid.
As shown in fig. 3, the base station 20 may include a base assembly 100, a maintenance assembly including a first maintenance assembly 200 and/or a second maintenance assembly 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 to the first maintenance assembly 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 primary function of the first maintenance assembly 200 is to suck up dust, debris and other debris collected in the dust collection portion of the surface cleaning apparatus and to store the sucked up debris. The second maintenance assembly 300 may include a cleaning liquid storage portion and a recovery liquid storage portion, and may be connected by a conduit, and the cleaning liquid stored in the cleaning liquid storage portion is provided to the fluid replacement port of the base assembly 100, and the cleaning liquid is provided to the surface cleaning apparatus, and the recovery liquid after self-cleaning the mop of the surface cleaning apparatus is pumped from the washing portion of the base assembly 100 to the recovery liquid storage portion through the conduit.
In the present disclosure, the first and second maintenance assemblies 200 and 300 may be selectively used in cooperation with the base assembly 100, so that base stations having different maintenance modes may be constructed. As shown in fig. 4, the self-emptying mode of the different maintenance modes may be achieved by mating the first maintenance assembly 200 with the base assembly 100. When the first maintenance assembly 200 is combined with the base assembly 100, the suction function of the garbage of the dust collecting part of the surface cleaning apparatus can be realized, so that the garbage of the dust collecting part of the surface cleaning apparatus is emptied to the first maintenance assembly 200, and thus the self-emptying function of the surface cleaning apparatus can be realized. As shown in FIG. 5, the second maintenance assembly 300 may be engaged with the base assembly 100 to implement a self-cleaning mode and/or a supplemental mode of different maintenance modes. In combination with the base assembly 100, the second maintenance assembly 300 may enable self-cleaning of the mop of the surface cleaning apparatus and/or may enable replenishment of the cleaning liquid receptacle of the surface cleaning apparatus with cleaning liquid. In addition, as shown in fig. 3, the first maintenance assembly 200 and the second maintenance assembly 300 may be used in cooperation with the base assembly 100 to implement a self-emptying mode, a self-cleaning mode, and/or a supplementary mode among different maintenance modes. In addition, a liquid recovery mode may be realized in which the liquid used in the self-cleaning mode is recovered and stored in the recovered liquid storage portion. Specifically, debris from the dirt collection portion of the surface cleaning apparatus can be drawn through the first maintenance assembly 200 to empty the dirt collection portion of the surface cleaning apparatus, and cleaning liquid can be replenished to the cleaning liquid receptacle of the surface cleaning apparatus and/or provided to clean the mop of the surface cleaning apparatus through the second maintenance assembly 300. In addition, the base assembly 100 may be used alone to effect charging of the surface cleaning apparatus, it being noted that even after the base assembly 100 is combined with the first maintenance assembly 200 and/or the second maintenance assembly 300, the charging mode may be selected simultaneously after the respective mode of the first maintenance assembly 200 and/or the second maintenance assembly 300 is selected. While the role of the first and second maintenance assemblies 200, 300 is expressly defined in this disclosure, this is by way of example only, and it will be understood by those skilled in the art that maintenance assemblies having other functions may be selected for use with the base assembly or with a single function maintenance assembly or with a functionally integrated maintenance assembly, etc.
According to the combinable 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 first maintenance assembly 200 and/or the second maintenance assembly 300 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 first maintenance assembly 200 can be selected and engaged with the base assembly 100 to empty the dust collecting portion of the surface cleaning apparatus, such that a self-emptying mode and/or a charging mode can be performed. For example, in the case where there is no need to empty the dust collecting part of the surface cleaning apparatus, only the second maintenance assembly 300 and the base assembly 100 may be selected, and only the self-cleaning mode, the liquid recovery mode, the 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 the 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 of the existing base station and allow the user to choose 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 first maintenance assembly 200 may be designed to be disposed at a middle portion, and the second maintenance assembly 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 first maintenance assembly 200 and the second maintenance assembly 300 are respectively provided with a combination 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 an external view using the first maintenance assembly 200 and the second maintenance assembly 300 is illustrated in fig. 4 and 5, that is, they may be accommodated in different housings. In the present disclosure, however, the first maintenance assembly 200 and the second maintenance assembly 300 may share a single assembly housing. The first maintenance assembly 200 and the second maintenance assembly 300 are both mounted into the assembly housing. Thus, when a user only needs the first maintenance assembly 200, the first maintenance assembly 200 can be assembled in the assembly housing, when only the second maintenance assembly 300 is needed, the second maintenance assembly 300 can be assembled in the assembly housing, and when the first maintenance assembly 200 and the second maintenance assembly 300 are needed, the first maintenance assembly 200 and the second maintenance assembly 300 can be assembled in the assembly housing. In this manner, assembly may occur prior to delivery of the product to the user, such that the user combines the maintenance assembly with the base assembly.
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, if the first maintenance assembly 200 and the second maintenance assembly 300 are provided with separate housings, the first maintenance assembly 200 or the second maintenance assembly 300 may be provided with a mounting structure. When the first maintenance assembly 200 and the second maintenance assembly 300 share an assembly housing, then a mounting structure may be provided on the assembly housing. 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. 6 and 8, an insertion opening 611 may be provided in the base member 100, and the insertion opening 611 may be inserted by an insert provided in the maintenance member. And the insert may be locked by the locking member 612 after insertion. In an alternative embodiment, an insert may be provided in the base assembly and an insert port 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 first maintenance assembly 200 and the second maintenance assembly 300 share the assembly housing, the volume of the base can be effectively reduced. FIG. 6 illustrates a mounting structure according to one embodiment of the present disclosure. An insert 3010 may be provided at the lower housing 301 of the maintenance assembly, wherein the insert 3010 may protrude outward with respect to the lower housing 301, and may be provided with a locking port 3011. When a user assembles the maintenance component with the base component, the insert 3010 may be inserted into the insertion port 611. A locking member 612 may be provided at a corresponding position of the base member 100, wherein the locking member 612 can be operated by a user to lock or release the insertion member 3010, for example, the user can toggle an operation portion 6121 of the locking member 612 in the left-right direction shown in fig. 6, so that a projection 6122 of the operation portion 6121 can enter the locking port 3011 or leave the locking port 3011, and lock when entering and release when leaving. The latch 612 may further include a latch housing 6123, and the operating portion 6121 may be disposed in the latch housing 6123 and may be slidable inside the latch housing 6123. The operation portion 6121 may further include a locking member 6124. When the locking member 612 locks the insert 3010, the locking member 6124 of the operating portion 6121 may abut against the locking groove 6125 of the locking member housing 6123, so that the insert 3010 and the locking member 612 are not easily separated, which may ensure that the insert 3010 may be stably locked by the locking member 612 without the user applying force to the operating portion 6121 to release the insert 3010.

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 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 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 interface 130, and the suction interface 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 dust collecting portion of the surface cleaning apparatus, such that, in a self-emptying mode using the first maintenance assembly 200, waste from the integrated portion of the surface cleaning apparatus is sucked into the first maintenance assembly 200 via the interface 131 via the interfaced suction interface 130 and 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 surface of the base assembly 100, for example, may be provided on an inner side surface of the first casing 111, or the second casing 112, or the third casing 113, and. 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. This may be provided, for example, 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 replacement interface 140 may extend outwardly from a surface of the inner side of the base assembly 100 by a predetermined length, and the fluid replacement interface 140 may be extended and retracted to be inserted into a fluid replacement 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 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 second maintenance assembly 300 via a conduit to provide cleaning fluid from the second maintenance assembly 300 to the surface cleaning apparatus for purposes of cleaning fluid replenishment.

Wherein the removable orientation of the evacuation collection portion 220 with respect to the first maintenance assembly housing 210 is substantially parallel to the ground orientation in which the base station is disposed. After the first maintenance assembly 200 with the evacuation collection portion 220 mounted thereon is assembled to the base assembly 100, the evacuation collection portion 220 is in fluid communication with the suction port 130 of the base assembly 100 via a conduit. This can suck the dust in the dust collecting part of the surface cleaning apparatus into the storage space of the emptying collection part 220 to thereby achieve the emptying of the dust collecting part. Alternatively in the present disclosure, the receiving volume of the evacuation collection portion 220 may be set to at least three times or more the receiving volume of the dust collection portion of the surface cleaning apparatus. When it is desired to disengage the evacuation collection portion 220 from the first maintenance assembly housing 210, a user may press it, causing the evacuation collection portion 220 to eject by the action of a spring force.
Fig. 13 shows a schematic view of the first maintenance assembly 200 shown in fig. 12 with the outer housing removed. As shown in fig. 13, the first maintenance assembly 200 may include a first suction source 230, which first suction source 230 may be in the form of a fan, and is disposed inside the first maintenance assembly housing 210. In the present disclosure, the first suction source 230 and the evacuation collection portion 220 may be disposed to the left and right of the first maintenance assembly housing 210. A suction airflow is generated by the first suction source 230 such that a negative pressure state is created by the suction airflow such that debris such as dust enters the suction channel of the evacuation collection portion 220 from the surface cleaning apparatus via the suction interface and the corresponding duct, for example the suction channel may interface with a duct port provided on 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 evacuation collection portion 220 through the suction inlet port.
Fig. 14 shows a schematic view of another angle of emptying the collection portion. Wherein the emptying collection part 220 defines a receiving space for receiving and accommodating the garbage by its housing. The evacuation collection portion 220 may include a suction inlet port 226, wherein the suction inlet port 226 may be in communication with the suction interface 130 through a conduit to allow dust, debris, and the like debris to enter the interior of the evacuation collection portion 220. According to an embodiment of the present disclosure, as shown in fig. 15, the evacuation collection portion 220 may further include a first air outlet 227 and a second air outlet 228. Wherein in an alternative embodiment of the present disclosure, the suction inlet port 226 is disposed at one side surface of the housing of the evacuation collection portion 220, and the first and second air outlets 227 and 228 may be disposed at the other side surface of the housing of the evacuation collection portion 220. The one side and the other side may be two opposite sides of the housing of the evacuation collection portion 220. And the suction inlet port 226 and the first outlet port 227 may be offset leftward with respect to a center line of the evacuation collection portion 220, and the second outlet port 228 may be offset rightward with respect to a center line of the evacuation collection portion 220. The first air outlet 227 and the second air outlet 228 can communicate with the suction source 230 through an airflow passage 2301, as shown in fig. 12. The gas is caused to flow out of the first air outlet 227 or the second air outlet 228 by the suction action of the suction source 230, and is discharged by the suction source 230. Furthermore, as shown in fig. 14, a detection device 2261 may be further provided in the emptying collection part 220, and may be used at least to detect whether a dust bag or a cyclone, which is mentioned below, is in place. As an alternative embodiment, the location identified by the detection means 2261 in fig. 14 may be provided as a transparent area, and the presence of the dust bag or cyclone may be detected through the transparent area by a sensor provided at a corresponding location outside the evacuated collection chamber 220, which may be, for example, an infrared sensor. Further, as shown in fig. 14, a button 2262 may be further provided at the emptying collection portion 220 or the end cap portion 270 thereof, wherein the button 2262 may be provided at a lower position so that a user may take out the emptying collection portion 220 using the button when the emptying collection portion 220 is ejected by pressing.

As shown in fig. 15, the evacuation collection portion 220 may further include a switching portion 250. Fig. 13 shows a case where the switch portion 250 is attached to the casing of the evacuation collection portion 220, and fig. 15 shows a case where the switch portion 250 is separated from the casing of the evacuation collection portion 220. The switching portion 250 may be configured to switch the air passage, and may be set in a first state and a second state. In the first state, the switching portion 250 may cause the first outlet 227 to be open and the second outlet 228 to be closed, and in the second state, the switching portion 250 may cause the first outlet 227 to be closed and the second outlet 228 to be open. In the present disclosure, the first air outlet 227 may be disposed at a position closer to the suction inlet 226. Alternatively, the axis of the first air outlet 227 may coincide with the axis of the suction inlet 226, or the axis of the first air outlet 227 may be nearly coincident with the axis of the suction inlet 226, or the axis of the first air outlet 227 may be parallel to the axis of the suction inlet 226 in a plane perpendicular to the bottom side surface of the evacuation collection portion 220. For example, the first air outlet 227 may be provided at a position on the front side surface closer to the suction inlet 226. The second air outlet 228 may be arranged at a position relatively distant from the suction inlet 226 with respect to the distance between the first air outlet 227 and the suction inlet 226, for example, the second air outlet 228 and the suction inlet 226 may be arranged in an approximately diagonal manner, for example, the central axis of the second air 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 evacuation collection portion 220 may be provided with a cyclone separator or a dust bag. That is, the evacuation collection portion 220 may employ an interchangeable structure of a cyclone and a dust bag. Fig. 16 shows a schematic view in which the end cap portion 270 of the evacuation collection portion 220 is removed to show the inner space of the evacuation collection portion 220. In the case where a cyclone separator is installed as shown in fig. 16, a mounting structure 241 may be provided on an inner sidewall of the evacuation collection portion 220, and the cyclone separator 240 and the dust bag may be installed through the mounting structure 241 to the receiving space of the evacuation collection portion 220 such that an inlet of the cyclone separator or 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 outlet 227 serves as an outlet when the cyclone separator is used, and the second outlet 228 serves as an outlet when the dust bag is used. When the cyclone separator is used, the first outlet 227 is selected to select an air passage close to the suction inlet 226, dust and other debris are thrown into the accommodating space formed by the casing of the evacuation collection portion 220 by the cyclone separator, and air is discharged through the first outlet 227 butted against the outlet of the cyclone separator. In the case of using the dust bag, the second air 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 air 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 outlet 228 and thus the remote air path when the dust bag is in use, the dust bag can be made to fill the entire accommodating space when the air flows through the dust bag, so that the accommodating space can be fully utilized. As shown in fig. 15, the switching portion 250 may be provided with a first opening 251 and a second opening 252. The switching part 250 may slide with respect to the outer side surface of the emptying collection part 220 so that one of the first air outlet 227 and the second air outlet 228 serves as an air discharge port according to the use of the cyclone separator or the dust bag. When the cyclone separator is used, the switching portion 250 slides to a first state in which the first opening 251 of the switching portion 250 is located at the position of the first outlet 227, so that the first outlet 227 serves as an air discharge port for the recovered air stream, and the second outlet 228 is blocked by the switching portion 250. In the case of using the dust bag, the switching portion 250 slides to the second state in which the second opening 252 of the switching portion 250 is located at the position of the second outlet 228, so that the second outlet 228 serves as an air outlet for the recovered air flow, and the first outlet 227 is blocked by the switching portion 250. It is to be noted that, although the switching portion provided with the first opening and the second opening is exemplified in the above description, the description is made. It should be understood by those skilled in the art that the switching portion may take other forms as long as it can block one of the first gas discharge port and the second gas discharge port and open the other during the switching of the switching portion. For example, the switching portion may be provided in a plate shape without an opening, and the length thereof is designed according to the distance between the first gas discharge port and the second gas discharge port, and the corresponding function can be achieved as well.
Optionally, the emptying collection portion 220 may include a discharge portion 223, which discharge portion 223 can be closed to form a closed waste containing space and also opened to facilitate a user to pour out waste (collected by way of the cyclonic separator) in the containing space. In an alternative embodiment, the discharge portion 223 may be in the form of a discharge gate, and one side of the discharge gate may be rotated about a side housing of the empty collection portion 220 to be opened or closed. In addition, a locking member 224 may be provided at the other side of the housing of the evacuation collection portion 220 corresponding to the other side of the discharge door. As an example and not by way of limitation, the lock 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 portion 223 may be disposed at one side surface of the evacuation collection portion 220, and the end cover portion 270 may be disposed at the other side surface of the evacuation collection portion 220, wherein the one side surface is an opposite side surface to the other side surface, and the two side surfaces are side surfaces adjacent to the side surfaces where the first air outlet 227, the second air outlet 228, and the suction inlet 226 are located.
Fig. 17 shows a schematic cross-sectional view of the evacuation collection section 220. Fig. 17 shows an automatic switching structure of the switching unit 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 casing of the evacuation collection portion 220, when a certain pressure is applied to the first spring 229, the first spring 229 may be compressed, that is, the switching portion 250 may move toward the second air outlet 228 (leftward), and when the pressure of the first spring 229 is released, the switching portion 250 may move toward the first air outlet 227 (rightward). In this way, when it is necessary to mount the cyclone 240 into the evacuation collection portion 220, the switching portion 250 is moved leftward by the structure of the cyclone 240, and after the cyclone 240 is mounted in place, the switching portion 250 is maintained at a position of a first state in which the first opening 251 opens the first outlet 227. When the cyclone separator 240 is detached, the switching part 250 is moved rightward by the tension of the first spring 229, so that the position of the switching part 250 can be moved to a second state in which the first opening 251 is closed and the second outlet 228 is opened by the second opening 252 without installing the cyclone separator 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 toggle the switching part when the cyclone separator and the dust bag are replaced under the condition that the switching part 250 is switched manually can be avoided. As shown in fig. 17, a first groove 2201 may be provided inside the casing of the evacuation collection portion 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 snap into the first groove 2201 to secure the cyclone 240 to prevent the cyclone 240 from being dislodged. In a case where it is necessary to take out the cyclone 240 from the evacuation collection portion 220, the user may operate the snap 2401 so that the snap 2401 disengages from the first groove 2201 to take out the cyclone 240.
According to an embodiment of the present disclosure, the evacuation collection portion 220 may be taken out or mounted to the inside of the housing of the first maintenance assembly 200 by press-fitting.

Wherein the body portion is positionable in and movable along the receiving member 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 may be inserted into the first recess 2221 to lock the evacuated collection portion 220 to the housing of the first maintenance assembly 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. 22 and 23. The receiver 280 may be secured to the housing of the first maintenance assembly 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 entry 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 drain collection portion 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 by the guidance of 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 state in the locking slot 2225 in fig. 23 (a partial enlarged view of fig. 22).
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 empty collection portion 220 into the housing.

Preferably, in the present disclosure, the cleaning liquid and the detergent may be received through pipes and supplied into the mixing part 370 together, for example, the cleaning liquid and the detergent may be received through a three-way valve (e.g., as shown in a region a of fig. 19) and supplied together to the mixing part 370 through an inlet pipe. The mixed liquid of the mixing tank 370 may be additionally provided to the base assembly 100 through a third liquid distribution structure, which may include a third pipe 431, a third pumping part 432, a mixed liquid supply port 433, and a supply pipe 434. The third conduit 431 may communicate with an outlet interface 376 of the mixing section 370, the mixed liquid is supplied to the mixed liquid supply port 433 through a supply conduit 434 by a pumping action of the third pumping section 432 via the third conduit 431, and the mixed liquid is supplied to the base assembly 100 by an abutment of the mixed liquid supply port 433 with a corresponding portion of the base assembly 100, the third pumping section 432 of the present disclosure preferably employing a diaphragm pump. Furthermore, a detergent storage section detection device 451 may be provided, wherein the detergent storage section detection device 451 may be used to detect whether the detergent storage section is in a corresponding position, i.e. to detect whether the detergent can be supplied. The detergent storage part detection device 451 may be disposed below the detergent storage part, and may take the form of a photoelectric sensor.
The fourth liquid distribution structure may include a fourth conduit 441, and the fourth conduit 441 may be in communication with the base assembly 100 via a fourth inlet port 442, so as to draw the recovered liquid from the base assembly 100 after the mopping of the mop in the base assembly 100. Furthermore, the fourth liquid distribution structure may further comprise a fourth pumping means, wherein the fourth pumping means may for example be a vacuum pump 443. The exhaust conduit 444 may be in communication with a vacuum pump 443. The recovery liquid storage portion 360 can be brought into a vacuum state by the operation of the vacuum pump 443, so that the recovery liquid can be drawn into the recovery liquid storage portion 360 through the fourth conduit 441, and the drawn gas is discharged through the exhaust conduit 444 while the recovery liquid remains in the recovery liquid storage portion 360.
Fig. 48-50 show schematic views of a mixing bin 370 according to one embodiment of the present disclosure. As shown, the mixing cartridge 370 may include a first impeller portion 371, a second impeller portion 372, and a drive shaft 373. The first impeller portion 371, the second impeller portion 372, and the drive shaft 373 are housed in a housing of the mixing chamber 370. As shown in fig. 47, the mixing part 370 may receive the detergent and the cleaning liquid from the three-way valve through pipes. The mixed liquid in the mixing section 370 may be provided to the base assembly 100 and/or the surface cleaning apparatus through the third conduit 431. For example, an inlet interface 375 and an outlet interface 376 may be provided on the housing of the mixing section 370, wherein the inlet interface 375 may receive the detergent and the cleaning liquid and the outlet interface 376 may provide the mixed liquid to the third conduit. It will be appreciated by those skilled in the art that instead of a three-way valve as described above, the mixing section 370 may be provided with separate inlets for receiving detergent and cleaning liquid, respectively.
In the present disclosure, the inlet interface 375 may be disposed corresponding to the first impeller portion 371. As shown in fig. 49 (showing the internal structure), the first impeller portion 371 may include a plurality of first blades, wherein the surface of the first blade may be configured as an arc surface to receive the impact force and/or the gravity of the liquid entering the inlet interface 375, so that the first impeller portion 371 may be rotated by the liquid from the inlet interface 375. The first impeller portion 371 may be fixedly secured to the transmission shaft 373, and the second impeller portion 372 may also be fixedly secured to the transmission shaft 373. When the first impeller portion 371 rotates, the transmission shaft 373 will be driven to rotate, so that the second impeller portion 372 also rotates. In the present disclosure, the first impeller portion 371 may be regarded as a rotation driving portion, and the second impeller portion 372 may be regarded as a rotation driven portion. The cleaning liquid such as cleaning water and the like and the cleaning agent such as detergent and the like entering the mixing chamber 370 are mixed by the rotation of the second impeller portion 372, and thus, the second impeller portion 372 serves as a stirring means. The mixed liquid may be supplied to the outside through a third pipe 431 provided near the bottom of the mixing bin 370 after sufficient mixing.
The driving shaft 373 may be supported on the top surface of the mixing chamber 370 by the first bearing 3731 and supported on the bottom surface of the mixing chamber 370 by the second bearing 3732, which may effectively reduce the rotational resistance and avoid the generation of noise. The first and second impeller portions 371, 372 may be fixed to the drive shaft 373 by axial and radial fastening means, respectively. As an example, the first impeller portion 371 may be secured to the drive shaft 373 by a first axial snap spring 3733 and a first radial snap groove 3734, and the second impeller portion 372 may be secured to the drive shaft 373 by a second axial snap spring 3735 and a second radial snap groove 3736. By this fixing means, it is possible to effectively prevent the first impeller portion 371 and the second impeller portion 372 from jumping radially and axially during operation. Of course, it will be appreciated by those skilled in the art that other forms of securing may be used. According to the internal arrangement mode of the mixing bin disclosed by the invention, various advantages such as compactness, low noise, low cost and the like can be realized.
In the present disclosure, the direction of impingement of the fluid F entering the mixing bin 370 from the inlet interface 375 may be radial to the blades, see, for example, fig. 50 and 51. Alternatively, the force receiving point of each blade of the first impeller portion 371 may be located at the middle position of the blade, so that the first impeller portion 371 can be rotated well by the fluid impact, and the impact direction of the fluid may be substantially the radial direction of the blade. Each of the blades of the first impeller portion 371 is formed in an arc surface, and an axial included angle of the arc-shaped blade may range from 5 ° to 85 °. For example, from the lower portion of the arc-shaped blade to the upper portion of the arc-shaped blade (the up and down as referred to herein means the up and down in the state where the arc-shaped blade is in the operating state), the angle of the arc-shaped blade is gradually decreased with respect to the axial direction of the drive shaft. Thus, the arc-shaped blades have a predetermined inclination angle with respect to a direction perpendicular to the axial direction of the drive shaft. And each blade of the first impeller portion 371 is inclined in the rotation direction from the lower portion of the blade to the upper portion of the blade.
In the present disclosure, rather than providing the inlet interface 375 at the upper sidewall of the mixing silo 370, the inlet interface 375 may also be provided at the top of the mixing silo 370 and the incoming fluid may be directed at the blades, such as by the kinetic and potential energy of the fluid causing the first impeller portion 371 to rotate, as described above.
Each blade of the second impeller portion 372 is an arc surface, and the axial included angle range of the arc-shaped blade may be 5 ° to 85 °. For example, from the upper portion of the arc-shaped blade to the lower portion of the arc-shaped blade (the up and down as referred to herein means the up and down in the state where the arc-shaped blade is in the operating state), the angle of the arc-shaped blade is gradually decreased with respect to the axial direction of the drive shaft. Thus, the arc-shaped blades have a predetermined inclination angle with respect to a direction perpendicular to the axial direction of the drive shaft 373. And each blade of the second impeller portion 372 is inclined against the rotation direction from the upper portion of the blade to the lower portion of the blade, so that the cleaning agent and the cleaning liquid can be more sufficiently agitated by the second impeller portion 372 as the agitating means.
According to the mixing bin 370 disclosed by the invention, under the condition of a certain space, the kinetic energy and the energy of the entering cleaning liquid can be fully utilized to complete the stirring and mixing of the mixed liquid, so that various advantages of low noise, low cost and the like are realized. Therefore, in the mixing bin disclosed by the invention, a good stirring effect can be realized under the condition that a motor and a speed reducing device are not used.
Further, in the second maintenance assembly 300, an air flow generating device may be further provided, wherein the air flow generating device may include a first air flow generating device 510 and a second air flow generating device 520. The airflow provided by the first airflow generating device 510 is transmitted to the first inlet 512 of the susceptor assembly 100 through the first airflow port 511, and a heating device such as a PTC heater may be disposed near the first inlet 512 so as to heat the airflow by the heater to form a hot airflow for drying treatment. The airflow provided by the second airflow generating device 520 is delivered to the second inlet 522 of the base assembly 100 via the second airflow port 521, and a heating device 1157 (see fig. 12) such as a PTC heater may be provided near the second inlet 522 so as to heat the airflow by the heater to form a hot airflow for drying treatment. As an alternative, the airflow generating means may directly provide the flow of hot air without the need for heating devices in the base station assembly 100. As a further alternative, the gas flow generating means may be arranged at the base station assembly 100, while also in this way heating means may be arranged at the base station assembly.
As an alternative embodiment, a liquid level detection device 374 may also be disposed in the mixing bin 370, wherein the liquid level detection device 374 may be used to detect the height of the liquid level in the mixing bin 370. Wherein the liquid level detection device 374 may be used to detect a lower liquid level threshold and an upper liquid level threshold in the mixing bin 370. The level detection device 374 may be formed by one detector or more than two detectors to detect the lower level threshold and the upper level threshold. Here, three liquid level detection means are shown, wherein a first liquid level detection means may be used for detection of a lower liquid level threshold, a second liquid level detection means may be used for detection of a higher liquid level threshold, and a third liquid level detection means may be used in cooperation with the first liquid level detection means and the second liquid level detection means, respectively, for verification, etc.
According to an example of the present disclosure, the detergent storage part 340 is a detachable structure with respect to the second maintenance assembly 300, and the detergent storage part 340 can be replaced by a user. As shown in fig. 52, a housing 3410 in which a cleaning agent storage part 340 can be accommodated on the second maintenance assembly 300, and the cleaning agent storage part 340 can be inserted into the housing 3410, for example, the housing 3410 may be provided with an opening (for example, may be provided at an upper portion of the second maintenance assembly 300) into which the cleaning agent storage part 340 is inserted. In order to allow locking and unlocking of the detergent storage part 340, a reset lock 3420 may be further included as an embodiment, wherein locking and unlocking of the detergent storage part 340 are achieved by cooperation of the reset lock 3420 and a locking structure of the detergent storage part 340 described below. Further, the user may insert and fix or eject the detergent storage part 340 by pressing it to be unlocked, and according to one embodiment, may further include a return spring 3430, and the return spring 3430 may be used at least to eject the detergent storage part 340. Further, the return spring 3430 may be in direct contact with the return latch 3420, and preferably, an ejector 3440 may be provided, wherein the ejector 3440 may be disposed between the return spring 3430 and the return latch 3420 so that the return latch 3420 is ejected by the elastic force of the return spring 3430 when the detergent storage part 340 is in the unlocked state, for example, the return latch 3420 may be ejected by the elastic force applied to the ejector 3440. In the present disclosure, an ejection spring 3450 may be further provided, and the ejection spring 3450 may be engaged with the ejector 3460 to eject the detergent storage part 340 from the housing 3410.
The self-locking resilient structure of the detergent storage part 340 according to an embodiment of the present disclosure will be described in detail below.
Fig. 52 shows a case where the cleaning agent storage part 340 is placed in the housing 3410. Therein, the lower portion of the housing 3410 may be provided with an opening 3411, and the outlet end 3401 of the detergent storage part 340 may pass through the opening 3411 so as to be engaged with the reset catch 3420 and to supply the detergent to the mixing bin. As shown in fig. 53, the outlet end 3401 may be configured to include a guide channel and a groove, wherein the outlet end 3401 may be configured to cooperate with the protrusions 3421 of the reset shackle 3420 to achieve the switching between the locked state and the unlocked state. The outlet end 3401 may include an indentation 3402, wherein the indentation 3402 may be accessible by the protrusion 3421.
As shown in fig. 54, the outlet end 3401 may further include a first guide channel 3403 and a retaining groove 3404. Wherein the first guide passage 3403 is used to connect the notch 3402 and the retaining groove 3404 so that, in the case where the detergent storage part 340 is pressed, the entering protrusion 3421 from the notch 3402 will slide into the retaining groove 3404 along the first guide passage 3403, for example, can slide into the retaining groove 3404 along the guide wall of the first guide passage 3403. Wherein the height of the limiting groove 3404 is higher than the height of the gap 3402, and the first guide channel 3403 extends upward from the gap 3402 to the limiting groove 3404, which may be arc-shaped and may include two sidewalls to form a channel. The first sidewall 3403a may have an end located above the notch 3402 (spaced apart from the notch 3402 by a certain distance, and one end of the first sidewall 3403a may be deviated at a central position of the notch 3402, for example, in a direction away from the stopper groove 3404) as a starting point, and an end point provided to the stopper groove 3404. The second side wall 3403b starts at the notch 3402, and a terminal point may be disposed below the limiting groove 3404 (spaced apart from the limiting groove 3404). The third sidewall 3404a of the groove corresponding to the first sidewall 3403a may be disposed to be straight (perpendicular to a horizontal plane on which the boundary of the notch is located) so as to define the position of the protrusion 3421. It should be noted that, during the process of sliding the protrusion 3421 into the limiting groove 3404, the reset lock 3420 rotates because the detergent storage part 340 is stationary.
The outlet end 3401 may further include a second guide passage 3405, the second guide passage 3405 including a fourth side wall 3405a, a fifth side wall 3405b, and a sixth side wall 3405c, and being substantially V-shaped. And a locking groove 3405d is provided between the fourth side wall 3405a and the fifth side wall 3405 b. After the projection enters the latching groove, the projection abuts against the latching groove due to an elastic force of a return spring described below, so that the detergent storage part 340 is latched. The outlet end 3401 may further include a non-limiting groove 3406 in which one end of a fourth sidewall 3405a meets one end of a second sidewall 3403b, and the other end of the fourth sidewall 3405a meets one end of a fifth sidewall 3405 b. One end of the fourth sidewall 3405a is located at a higher height than the other end of the fourth sidewall 3405 a. And the other end of the fifth sidewall 3405b is located at a higher height than the one end of the fifth sidewall 3405 b. One end of the sixth sidewall 3405c is connected to one end of the third sidewall 3404a and the other end extends to the non-limiting groove 3406, and the one end of the sixth sidewall 3405c is located at a lower height than the other end of the sixth sidewall 3405 c. When the protrusion 3421 is located in the position-limiting groove 3404 and the detergent storage part 340 is in a locked state, if the detergent storage part 340 is pressed again, the detergent storage part 340 will bring the reset lock 3420 together and move downward. When the user finishes pressing, the protrusions 3421 will enter the second guide channels 3405 due to the rotation of the reset lock 3420 and the elastic force of the reset spring 3430, and the protrusions 3421 will enter the non-limiting grooves 3406 along with the rotation of the reset lock 3420 by the guiding action of the side walls of the second guide channels. The detergent storage part 340 is lifted up by a predetermined height.
After that, the user can take out the detergent storage part 340. During removal, the protrusion 3421 can slide along the third guide channel 3407 until the protrusion 3421 moves to the next notch, so that the detergent storage part 340 can be separated from the reset lock 3420. The third guide passage 3407 may include a seventh side wall 3407a and an eighth side wall 3407b, wherein one end of the seventh side wall 3407a may be joined with the other end of the fifth side wall 3405b, and the other end of the seventh side wall 3407a may extend to the next gap. One end of the eighth sidewall 3407b may be connected with the non-limiting groove 3406, and the other end may be connected with the first sidewall of the next self-locking resilient structure.
In the above embodiments, one of the self-locking rebounding structures is described, which may be arranged circumferentially around the outlet end 3401 so that the protrusions 3421 may enter from one locking structure form into another, for example, the number of the locking structures may be N, where N ≧ 2, so that the self-locking rebounding operation may be repeated. In the present disclosure, four locking structures may be provided around the circumference of the outlet end 3401, such that when the reset lockout 3420 is rotated 90 °, it may be switched from one locking structure to another, thereby allowing a self-locking rebound operation to be performed again. However, the number of the locking structures may be different, and for example, the number may be six, and in the case of six locking structures, the reset lock 3420 performs the next self-locking rebounding operation each time it rotates at 60 ℃. In addition, in the case of four locking structures, four protrusions 3421 are correspondingly provided on the reset lock 3420, and in the case of six structures, six protrusions 3421 are correspondingly provided on the reset lock 3420, and the number of the protrusions may be the same or different. For example, the number of the convex parts can be M, wherein M is more than or equal to 2, M can be equal to or not equal to N, and M can be less than N under the condition of not being equal to N. The reset lockout 3420 is rotatable 360/N degrees each time during the process of switching between the locked state and the unlocked state.
During the rotation of the reset lock 3420, since there is an elastic force of the reset spring 3430, when the user releases the detergent storage part 340 after pressing the detergent storage part 340, the reset lock 3420 is subjected to an upward elastic force due to the elastic force of the reset spring 3430 and is pushed up (e.g., may be applied to the reset lock 3420 by the push-out member 3440), so that after the protrusion 3421 is disengaged from the locking groove, the protrusion 3421 enters the third guide path due to the elastic force of the reset spring 3430, and the protrusion 3421 enters the non-limiting groove 3406 as the reset lock 3420 rotates.
Further, an ejection spring 3450 and an ejector 3460 may be further provided, wherein the ejection spring 3450 is engaged with the ejector 3460 for ejecting at least a portion of the detergent storage part 340 to the outside of the housing. Among them, the lifters 3460 may contact with the bottom surface of the detergent storage part 340 and may pass through the housing 3410.
According to one example of the present disclosure, the reset lockout 3420 may be a ring-like structure, such as shown in fig. 54, and the protrusions 3421 may be located on an inner circumferential surface of the reset lockout 3420. And a stopping structure 3422 may be further disposed on the reset lock 3420. The latching structure 3422 may correspond to the latching recess 3412 provided in the housing 3410. As an example, a latching recess 3412 corresponding to the latching structure 3422 may be provided on the bottom outer surface of the housing 3410. As shown in fig. 54, further, the reset lock 3420 may further include a catching structure 3422, and the catching structure 3422 may be disposed on an outer circumferential surface of the reset lock 3420, and may be an arm portion extending from the outer circumferential surface, and a catching protrusion may be disposed at an end of the arm portion. For example, at least when the detergent storage part 340 is in a locked state, the latching protrusion may slide into the latching groove 3412 to further restrict the rotation of the reset lock 3420, wherein the number of the latching structures 3422 may be provided in plural, preferably the same as the number of the protrusions 3421 of the reset lock 3420.
Although the above-described resilient latch structure is described in the present disclosure in connection with a base station, it will be understood by those skilled in the art that the resilient latch structure may be used in other aspects and is not limited to the base station described in the present disclosure.
According to the technical solution of the present disclosure, the cleaning agent storage part 340 is separately provided from the cleaning liquid storage part 350 and the recovery liquid storage part 360 and is disposed at the rear side of the adjacent position of the cleaning liquid storage part 350 and the recovery liquid storage part 360. The user can lock only by pressing the detergent storage 340 and unlock by pressing again. This eliminates the need for a release button or the like.
Generally, the detergent storage part 340 may be replaced to be inserted into the second maintenance assembly 300, but there may be a case where a leakage or the like occurs in the detergent storage part 340.
In the present disclosure, a two-stage valve structure may be provided inside the outlet end 3401 of the detergent supply device 340. The two-stage valve structure may be disposed upstream and downstream of the fluid. The first stage may be a one-way valve and may be disposed upstream of the fluid. And the second stage valve member may be a two-way valve, a one-way valve, and may be disposed downstream of the fluid. Thus, the leakage condition can be effectively prevented through the two-stage sealing structure. The upstream and downstream described herein are for upstream and downstream when the liquid flows out from the container (the detergent supply device 340).
Suitable valve configurations may be selected in the present disclosure to prevent leakage. As one example, the first stage valve structure may be a first stage check valve and the second stage valve structure may be a second stage valve member, which may be in the form of a second stage check valve, a ball valve, or the like, as examples. The first stage of the first stage check valve allows flow to be configured to: the liquid is allowed to flow through the first stage one-way valve in a first flow direction, the first flow direction is the direction from the upstream to the downstream of the outflow path of the liquid, the liquid is prevented from flowing through the first stage one-way valve in a second flow direction, and the second flow direction is the direction from the downstream to the upstream of the outflow path of the liquid. The second stage of the second stage valve member allows flow to be configured as: the liquid is allowed to flow through the second stage valve member in the first flow direction and/or the second flow direction. The first stage allowed flow direction and the second stage allowed flow direction referred to in this disclosure may be the designed flow direction of the valve itself. For example, the first stage allows flow in a direction that the first stage check valve allows fluid flow without external force being applied thereto, and the second stage allows flow in a direction that the second stage valve allows fluid flow without external force being applied thereto. In summary, in the present disclosure, the first stage allows the flow direction to be the first flow direction. The second stage allows the flow direction to be the first flow direction; or in a second flow direction; or a first flow direction and a second flow direction.
For example, in the case where the first stage check valve is a first duckbill valve, the first stage check valve may be designed to flow in an upstream to downstream direction, and in the case where the second stage valve member is a second duckbill valve, the other duckbill valve may be designed to flow in a downstream to upstream direction. Thus, two duckbill valves designed to flow in opposite directions can be mated to prevent fluid leakage. When the liquid is allowed to flow out (external force is applied), the first duckbill valve can be opened by suction, the liquid flows out to the second duckbill valve according to the designed flow direction of the first duckbill valve, and the second duckbill valve can be pushed open to form a flow path, so that the liquid can flow from the upstream to the downstream through the second duckbill valve.
Preferably in the present disclosure, the first stage one-way valve may be a duckbill valve, wherein the duckbill valve may be made of a soft material, such as soft gel. The second stage valve member may be a ball valve. The ball valve can include a sealing ball, which can be received in a support body, which can be received inside the outlet end 3401, and a support body.
Fig. 55 shows an exploded schematic view of the detergent supply device 340, and fig. 56 shows a sectional view of the detergent supply device 340. A first stage check valve 3471, for example in the form of a duckbill valve, may be disposed within the outlet end 3401 at an upstream location, for example adjacent the inlet of the outlet end 3401. And a second stage valve member in the form of a sealing ball may be provided at a downstream location, such as an outlet adjacent the outlet end 3401. The second-stage valve member 3472 may include a sealing ball 3473 and a support body 3474. The sealing ball 3473 may be made of glass or the like. The support body may be made of a flexible material. The sealing ball 3473 disposed inside the support body may move inside the support body 3474. The supporting body 3474 may be designed to have a notch in the present disclosure, for example, as shown in fig. 55, and the supporting body 3474 can be opened and closed to allow the sealing ball 3473 to move. Furthermore, a blocking structure may be further disposed inside the supporting body 3474, and a function of one-way sealing may be achieved when the sealing ball 3473 abuts against the blocking structure 3476. The blocking structure may be arranged at a lower position of the support body. The support 3474 may be designed to limit the travel of the sealing ball 3473. For example, a stop structure 3477 may be provided, wherein the stop structure 3477 may be configured such that when the sealing ball is lifted, the sealing ball may move upstream. When the sealing ball is not jacked up, the limiting structure 3477 may apply a pressure to the sealing ball 3473 toward the downstream, so that the sealing ball 3473 abuts against the blocking structure, thereby achieving the sealing effect. Further, the spacing structure 3477 may not provide downstream directed pressure to the sealing ball 3473 in this disclosure. In the present disclosure, in order to allow the liquid to pass through the limiting structure 3477, a through hole may be opened on the limiting structure 3477 so as to allow the liquid to flow through when the limiting structure abuts against the sealing ball. Of course, it will be understood by those skilled in the art that the structure allowing the liquid to flow through may take other forms, such as providing notches, openings, teeth, etc. on the stopper 3477.
When the cleaning solvent supply device 340 is mounted to the second maintenance assembly 300, the docking port or a jacking structure provided at the docking port of the second maintenance assembly 300 may jack the sealing ball 3473 such that the sealing ball 3473 moves upstream and the sealing ball 3473 disengages from the blocking structure, thereby allowing fluid to drain. Furthermore, a pump device, such as a peristaltic pump, can be provided in the base station in order to draw liquid out of the cleaning agent supply 340. The sealing ball may also perform a sealing function to prevent residual liquid from flowing out when the detergent supply device 340 is taken out.
Generally, there is a risk of leakage when the detergent supply device 340 is inverted or squeezed. The solution of the present disclosure, through the two-stage sealing form, if liquid leaks from the first stage of sealing, the leakage risk will be greatly reduced due to the existence of the second stage of sealing. And after the sealing ball is placed in the base station, the sealing ball is jacked up, so that the liquid discharge is not influenced.
The cooperation of the surface cleaning apparatus with the base station will be described in detail below.
During use of the surface cleaning apparatus, whether the surface cleaning apparatus is returned to the base station may be determined based on the power level of the battery of the surface cleaning apparatus, the condition of the debris collected in the dust collection portion, the degree of cleanliness of the mop, and the like. For example, the surface cleaning apparatus may also be controlled to return to the base station for charging when the surface cleaning apparatus is low on power. In addition, when the surface cleaning apparatus has insufficient cleaning liquid, the surface cleaning apparatus may be controlled to return to the base station and initiate the replenishment mode. In addition, after the surface cleaning apparatus returns to the base station, the self-cleaning mode may also be activated to clean the mops of the surface cleaning apparatus and to clean and collect dirt from the mops of the surface cleaning apparatus, while the liquid recovery mode may also be activated. When the surface cleaning apparatus is docked with the base station, the drive wheels of the surface cleaning apparatus stop rotating. And the charging contacts of the two may be coupled to charge a battery of the surface cleaning apparatus. Once docked, a self-cleaning mode, a liquid recovery mode, a replenishment mode, and/or a self-emptying mode may be initiated.
The surface cleaning apparatus may be used for dry cleaning and/or wet cleaning of a cleaning surface. During the dry cleaning process, the rolling brush part and the side brush part are matched with each other to collect the garbage such as the debris into the dust collecting part of the surface cleaning device. Wherein the chamber of the dust collecting part defines a storage space for storing debris, such as debris, sucked by the surface cleaning apparatus and the debris accumulates in the storage space due to gravity. When the dust collecting part is full of debris or the like, it can be indicated that the dust collecting case is full, and the air flow in the dust collecting case can be restricted from freely flowing. Alternatively, one or more capacity sensors for detecting a full state of the dust collecting part may be provided in the dust collecting part or in the exhaust passage of the dust collecting part. In some embodiments, the containment sensor may include a light emitter/detector arranged to detect when debris within the dirt collection portion has accumulated to a threshold level indicative of a full condition. When debris accumulates within the dust collection portion and reaches a dust collection portion full condition, the debris at least partially blocks the airflow, resulting in a pressure drop within the dust collection portion and a reduction in the velocity of the airflow. In other examples, the capacity sensor may include a pressure sensor for monitoring the pressure within the dust collection portion and detecting a full collection bin condition when a threshold pressure drop occurs. In some examples, the capacity sensor may include a speed sensor to monitor an airflow speed within the dust collection portion and detect a collection bin full condition when the airflow speed is below a threshold speed. In other examples, the capacitance sensor may comprise an ultrasonic sensor whose signal changes in response to an increase in the density of debris within the dirt collection portion such that a full signal is only emitted when debris is pressurized in the dirt collection portion. This prevents a situation when a relatively light fluffy piece extending from top to bottom in the dust collecting part triggers a full condition, while in fact a large volume is available for collecting refuse, such as pieces. When the dust collecting part is full (e.g., a full state is detected), it can be returned to the base station to start the self-emptying mode. The debris evacuation suction port 15 can be opened to empty debris into the first maintenance assembly 200 (e.g., when the base assembly 100 is used in combination with the first maintenance assembly 200). In some examples, when docked to a base station, the self-emptying suction interface 130 defined by the rear wall side location of the base assembly 100 abuts the suction port 15 of the surface cleaning apparatus, and the sealing structure provided at the ramp portion 116 may seal a corresponding location of the roller portion of the surface cleaning apparatus, thereby sealing the nozzle of the roller portion. At this time, inside the surface cleaning apparatus, the air flow path from the suction nozzle to the dust collecting part is blocked, and the air flow path from the dust collecting part to the suction port 15 is opened to allow the evacuation of debris and the like. 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, such 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.
Before the self-emptying mode is initiated, the surface cleaning apparatus may send an acknowledgement signal to the base station indicating that the surface cleaning apparatus has been successfully docked and is ready to begin self-emptying. For example, the radio frequency signal may be sent from the surface cleaning apparatus to the base station and back to the surface cleaning apparatus; or the pulse signal may be transmitted and received through a charging channel between the charging contacts. Alternatively, an infrared signal may be sent by the surface cleaning apparatus to an infrared receiver of a base station. The self-emptying mode may be manually initiated by the user by pressing a button of the display control to initiate the mode. The self-emptying mode may be locked by the processor/controller when the surface cleaning apparatus is not docked or docked successfully to prevent inadvertent activation of the self-emptying mode. Alternatively, the self-emptying mode may be automatic, such that the self-emptying mode is controlled by the processor/controller and the surface cleaning apparatus is automatically started upon docking and successful docking. For example, the self-emptying mode may be designed as a default setting configured to be after each cleaning operation of the surface cleaning apparatus; or after a predetermined run time; or when the battery power of the surface cleaning apparatus reaches a lower threshold. Further, the self-emptying mode may be initiated before the surface cleaning apparatus is docked with the base station, and movement of the surface cleaning apparatus into a docking relationship with the base station may be considered part of the self-emptying mode. In this case, the user may press an operable button or switch to initiate the self-emptying mode, the surface cleaning apparatus being driven to and docked with the base station.
Before the self-cleaning mode is initiated, the surface cleaning apparatus may send an acknowledgement signal to the base station indicating that the surface cleaning apparatus has been successfully docked and is ready to begin self-cleaning. For example, the radio frequency signal may be sent from the surface cleaning apparatus to the base station and back to the surface cleaning apparatus; or the pulse signal may be transmitted and received through a charging channel between the charging contacts. Alternatively, an infrared signal may be sent by the surface cleaning apparatus to an infrared receiver of a base station. The self-cleaning mode or the liquid recovery mode may be manually initiated by a user, who initiates the mode by pressing a button of the display control. The self-cleaning mode or the liquid recovery mode may be locked by the processor/controller when the surface cleaning apparatus is not docked or is docked successfully to prevent inadvertent activation of the self-cleaning mode or the liquid recovery mode. Alternatively, the self-cleaning mode or liquid recovery mode may be automatic, such that the self-cleaning mode or liquid recovery mode is controlled by the processor/controller and is automatically initiated upon docking and successful docking of the surface cleaning apparatus. For example, the self-cleaning mode or the liquid recovery mode may be designed as a default setting configured to be after each cleaning operation of the surface cleaning apparatus; or after a predetermined run time; or when the battery power of the surface cleaning apparatus reaches a lower threshold. Further, the self-cleaning mode may be initiated before the surface cleaning apparatus is docked with the base station, and movement of the surface cleaning apparatus into a docking relationship with the base station may be considered part of the self-cleaning mode. In this case, the user may press an operable button or switch to initiate the self-cleaning mode or the liquid recovery mode, the surface cleaning apparatus being driven to and docked with the base station.
When the supplemental mode is enabled, the processor/controller may enable the supplemental mode after the surface cleaning apparatus has returned to the base station and the docking is successful. The telescoping flexible fluid replacement interface can interface with a fluid replacement port of a surface cleaning apparatus to achieve a replacement mode. Before initiating the liquid replenishment mode, the surface cleaning apparatus may send a confirmation signal to the base station indicating that the surface cleaning apparatus has been successfully docked and is ready to begin replenishing liquid. For example, the rf signal may be sent from the surface cleaning apparatus to a base station and back to the surface cleaning apparatus; the pulse signal may be transmitted and received through a charging channel between the charging contacts. Alternatively, an infrared signal may be sent by the surface cleaning apparatus to an infrared receiver of a base station. The supplementary mode may be manually activated, and the user activates the mode by pressing a button of the display control section or the like. When the surface cleaning apparatus is not docked or docked successfully, the supplementary mode may be locked by the processor/controller to prevent inadvertent activation of the supplementary mode. Alternatively, the replenishment mode may be automatic, such that the replenishment mode is controlled by the processor/controller and the surface cleaning apparatus is automatically started when docked in the base station. For example, the supplemental mode may be designed as a default setting configured to be after each cleaning operation of the surface cleaning apparatus; or after a predetermined run time; or when the level of cleaning liquid of the surface cleaning apparatus reaches a lower threshold or when the battery charge of the surface cleaning apparatus reaches a lower threshold. The supplemental mode may be initiated prior to docking of the surface cleaning apparatus with the base station, and movement of the surface cleaning apparatus into docking relationship with the base station may be considered part of the supplemental mode. In this case, the user may press a user operable button or switch to initiate the replenishment mode, with the surface cleaning apparatus being driven to and docked with the base station for liquid replenishment.
