Description

TECHNICAL FIELD

[0001] The present disclosure relates to a recycling device for a base station, a dust discharging assembly, and a base station. BACKGROUND

[0002] When a floor cleaning robot cleans a surface such as a floor, it collects dirt such as dust on the surface in a dust box of the floor cleaning robot. When the amount of dirt such as dust in the dust box of the floor cleaning robot reaches a preset amount, the floor cleaning robot docks at a base station that cooperates with the floor cleaning robot, and dirt in the dust box can be transferred to the base station. To achieve collection of dirt, the base station generally uses a dust bag or a dust cup filtering method to collect garbage. When the base station uses a dust bag to collect garbage, the disposable dust bag needs to be replaced regularly; the use cost is relatively high. When a dust cup is used, it needs to be emptied and cleaned frequently, which is inconvenient to use. When the dust box, the dust cup, and the dust bag of the base station are interchanged, because the structures of the dust cup and the dust bag are different, the same set of dust collection air duct system is used, which causes insufficient use of the internal space of the dust box, and affects the use effect of the dust cup or the dust bag.

[0003] Therefore, it is necessary to provide a suitable recycling device to achieve excellent dust collection effect without affecting the dust collection effect and fully utilizing the space. SUMMARY

[0035] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are illustrative only and not limiting to the present disclosure. In addition, it should be noted that, in the drawings, only parts related to the present disclosure are shown.

[0036] It should be noted that the embodiments and features of the embodiments in the present disclosure can be combined if there is no conflict. The technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] Unless otherwise specified, the exemplary embodiments / instances shown will be understood as providing exemplary features of various details that can implement the technical concepts of the present disclosure in practice. Therefore, unless otherwise specified, the features of various embodiments / instances can be additionally combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0038] When a component is referred to as "on" or "above" another component, "connected to" or "bonded to" another component, the component can be directly on, directly connected to, or directly bonded to the other component, or there can be an intermediate component. However, when a component is referred to as "directly on" another component, "directly connected to" or "directly bonded to" another component, there is no intermediate component. For this reason, the term "connected" can refer to a physical connection, an electrical connection, etc., with or without an intermediate component.

[0039] For descriptive purposes, the present disclosure can use spatial relative terms such as "under", "below", "lower", "on", "above", "upper", "over", and "side" (e.g., as in "side wall") to describe a relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture. For example, if the device in the drawings were turned over, a component described as "below" or "under" another component or feature would then be positioned "above" the other component or feature. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. In addition, the device can be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptions used herein are interpreted in light of such other orientations.

[0040] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "comprise," "include," "contain," and / or "comprising," "including," and / or "contain" are used in the detailed description and / or claims, such terms are intended to be inclusive in a manner similar to the term "comprise" as an open transition term without precluding the presence of additional, non-recited members, elements, steps, operations, components, assemblies, and / or groups thereof. It is also noted that, as used herein, the terms "substantially," "approximately," and other similar terms are used as synonyms for "about," and are employed to designate

[0041] According to one embodiment of the present disclosure, a base station is provided. The base station can be used to dock an autonomous surface cleaning device, such as a robotic floor cleaner.

[0042] The surface cleaning device can include a substantially circular or rectangular plus circular housing. As shown in Figure 1 and 2 The surface cleaning device 10 can include a wet cleaning portion and a dry cleaning portion. The wet cleaning portion and the dry cleaning portion can be disposed at the bottom of the housing and can be in contact with a cleaning surface to wet clean and dry clean the cleaning surface.

[0043] The wet cleaning portion can include first and second rotators 11 and 12, and a mop (not shown) such as a mop cloth can be disposed on the first and second rotators 11 and 12, respectively. The first and second rotators 11 and 12 are arranged side by side and are rotatable about a rotation axis, respectively, to mop the cleaning surface while the first and second rotators 11 and 12 are in contact with the cleaning surface. A cleaning liquid container can be disposed inside the housing of the surface cleaning device, and a cleaning liquid is supplied to the mop through a cleaning liquid supply port, so that the cleaning surface is wet cleaned by the cleaning liquid absorbed by the mop.

[0044] The dry cleaning portion can include a rolling brush portion 13 and an edge brush portion 14, wherein the number of the edge brush portion 14 can be one or two, and when one edge brush portion is provided, it can be provided on one side of the surface cleaning device, and when two edge brush portions are provided, they can be provided on both sides of the surface cleaning device. During the cleaning of the cleaning surface, the edge brush portion 14 can rotate to gather the garbage such as debris near the rolling brush portion 13, so that the garbage is rolled into the dust collection portion provided inside the housing of the surface cleaning device by the rotating rolling brush portion 13, wherein the dust collection portion can be in the form of a dust collection box, and the garbage from the cleaning surface is collected and stored by the dust collection portion.

[0045] In the present disclosure, preferably, the wet cleaning portion can be provided at the rear side of the dry cleaning portion with respect to the working travel direction of the surface cleaning device. In this way, dry cleaning first and then wet cleaning can be achieved. In addition, the wet cleaning portion can be movable up and down. In this way, when the wet cleaning is not performed, the wet cleaning portion can be raised so as not to contact the cleaning surface. When the wet cleaning is performed, the wet cleaning portion can be controlled to contact the cleaning surface and can also be provided with additional pressure, so that the wet cleaning portion in contact with the cleaning surface can provide additional driving force or resistance to the surface cleaning device. In a specific cleaning scene where stubborn stains and the like need to be cleaned, the provided pressure can make the mopping piece of the wet cleaning portion more closely contact the cleaning surface, so that better cleaning effect can be achieved. In addition, although the wet cleaning portion is in the form of two rotating pieces in the present disclosure, it should be understood that it can also be provided as one rotating piece, for example, the rotating piece can be a track-type rotating piece, and the track-type rotating piece can be provided to rotate along or against the travel direction of the surface cleaning device, so as to achieve wet cleaning of the cleaning surface.

[0046] Figure 3 A base station 20 according to an embodiment of the present disclosure is shown. The base station can be docked with the surface cleaning device. After the surface cleaning device is docked to the base station, the garbage such as dust, debris and the like collected in the dust collection portion of the surface cleaning device is sucked to the base station to achieve emptying of the dust collection portion of the surface cleaning device, and / or charging the surface cleaning device, and / or washing the mopping piece of the surface cleaning device, and / or supplementing the cleaning liquid for the cleaning liquid containing portion of the surface cleaning device.

[0047] As Figure 3 shown, the base station 20 can include a base assembly 100, a dust discharge assembly 200 and a cleaning assembly 300.

[0048] The base assembly 100 can provide a containing space for containing the surface cleaning device, can charge the surface cleaning device through the charging interface 120 provided in the base assembly 100 when a part of the surface cleaning device enters the base assembly 100, and / or can suck the garbage such as dust and debris collected in the dust collecting part to the dust discharging assembly 200 through the suction interface 130 provided in the base assembly 100, and / or can supplement the cleaning liquid to the cleaning liquid containing part of the surface cleaning device through the liquid supplementing interface 140 provided in the base assembly 100, and / or can clean the mopping part of the surface cleaning device through the cleaning part provided in the base assembly 100.

[0049] The main function of the dust discharging assembly 200 is to suck the garbage such as dust and debris collected in the dust collecting part of the surface cleaning device, and store the sucked garbage. The cleaning assembly 300 can include a cleaning liquid storage part and a recovered liquid storage part, and can provide the cleaning liquid stored in the cleaning liquid storage part to the liquid supplementing interface of the base assembly 100 through the pipeline connection, and then provide the cleaning liquid to the surface cleaning device, and suck the recovered liquid after self-cleaning of the mopping part of the surface cleaning device from the cleaning part of the base assembly 100 to the recovered liquid storage part through the pipeline.

[0050] In the present disclosure, the dust discharging assembly 200 and the cleaning assembly 300 can be used in combination with the base assembly 100, so as to constitute the base station with different maintenance modes. As shown in Figure 4 When the dust discharging assembly 200 is combined with the base assembly 100, the suction function of the garbage in the dust collecting part of the surface cleaning device can be realized, so as to discharge the garbage in the dust collecting part of the surface cleaning device to the dust discharging assembly 200, thereby realizing the self-discharging function of the surface cleaning device. As shown in Figure 5 The cleaning assembly 300 can be combined with the base assembly 100 to realize the self-cleaning mode and / or the cleaning liquid supplementing mode in different maintenance modes. When the cleaning assembly 300 is combined with the base assembly 100, the self-cleaning of the mopping part of the surface cleaning device can be realized and / or the cleaning liquid can be supplemented to the cleaning liquid containing part of the surface cleaning device. In addition, as shown in Figure 3As shown, the dusting assembly 200, the cleaning assembly 300 and the base assembly 100 can be combined to realize the self-emptying mode, the self-cleaning mode and / or the liquid supplementing mode in different maintenance modes. Specifically, the dusting assembly 200 can be used to suck the garbage in the dust collection part of the surface cleaning device to empty the garbage in the dust collection part of the surface cleaning device, the cleaning assembly 300 can be used to supplement the cleaning liquid to the cleaning liquid containing part of the surface cleaning device and / or clean the mopping part of the surface cleaning device with the cleaning liquid. In addition, the base assembly 100 can be used alone to realize the charging of the surface cleaning device. It should be noted that even if the base assembly 100 is combined with the dusting assembly 200 and / or the cleaning assembly 300, the charging mode can be selected simultaneously after the corresponding mode of the dusting assembly 200 and / or the cleaning assembly 300 is selected. Although the functions of the dusting assembly 200 and the cleaning assembly 300 are specifically defined in the present disclosure, only examples are provided herein, and those skilled in the art should understand that maintenance assemblies with other functions can be selected to be combined with the base assembly, or maintenance assemblies with single function or integrated functions can be used.

[0051] According to the combinable base station of the present disclosure, users can select different assemblies according to needs to combine with corresponding surface cleaning devices, for example, the dusting assembly 200 and / or the cleaning assembly 300 can be detachably attached to the base assembly 100. For example, for a surface cleaning device that only performs dry cleaning, the base assembly 100 can be selected to charge the surface cleaning device, and if it is necessary to empty the garbage in the dust collection part of the surface cleaning device, the dusting assembly 200 can be selected and combined with the base assembly 100 to empty the garbage in the dust collection part of the surface cleaning device, so that the self-emptying mode and / or the charging mode can be realized. For example, in the case where it is not necessary to empty the garbage in the dust collection part of the surface cleaning device, only the cleaning assembly 300 and the base assembly 100 can be selected to realize the self-cleaning mode, the liquid supplementing mode and / or the charging mode. In addition, according to the combinable base station of the present disclosure, if a certain assembly is updated later, the user can easily replace the previous assembly with the updated assembly. The existing base station of the surface cleaning device usually has single function, and for the multifunctional base station, the volume is relatively large, the user's use cost is relatively high, and the base station cannot be switched according to the user's needs. Therefore, the combinable base station according to the present disclosure can solve the problems existing in the existing base station and allow users to choose certain functions by selecting hardware.

[0052] According to one optional embodiment of the base station of the present disclosure, the base assembly 100 can be designed to be disposed in the lower portion, the dust removal assembly 200 can be designed to be disposed in the middle portion, and the cleaning assembly 300 can be designed to be disposed in the upper portion. However, the positions of the assemblies can be changed according to actual conditions. In addition, the dust removal assembly 200 and the cleaning assembly 300 are respectively provided with a combination part combined with the base assembly 100. In addition, other functional assemblies can be provided to realize other working modes according to actual needs.

[0053] In addition, although the dust removal assembly 200 and the cleaning assembly 300 are shown in the appearance schematic diagram in Figure 4 and Figure 5 , that is, they can be accommodated in different housings. However, in the present disclosure, the dust removal assembly 200 and the cleaning assembly 300 can share one assembly housing. The dust removal assembly 200 and the cleaning assembly 300 are both installed in the assembly housing. In this way, when the user only needs the dust removal assembly 200, the dust removal assembly 200 can be assembled in the assembly housing only, when the user only needs the cleaning assembly 300, the cleaning assembly 300 can be assembled in the assembly housing only, and when the user needs the dust removal assembly 200 and the cleaning assembly 300, the dust removal assembly 200 and the cleaning assembly 300 can be assembled in the assembly housing. In this way, the assembly can be completed before the product is delivered to the user, so as to avoid problems in the process of assembly by the user, and the user can select different functions according to his own needs.

[0054] In order to allow the maintenance assembly to be reliably disposed on the base assembly 100, a mounting structure can be provided on the base assembly 100 and the functional assembly connected thereto. For example, when the dust removal assembly 200 and the cleaning assembly 300 are respectively provided with independent housings, the mounting structure can be provided on the dust removal assembly 200 or the cleaning assembly 300. When the dust removal assembly 200 and the cleaning assembly 300 share the assembly housing, the mounting structure can be provided on the assembly housing. As an example, the mounting structure can include an insertion piece and a locking piece, and the insertion piece can be provided on the maintenance assembly and the locking piece can be provided on the base assembly. As shown in Figure 7 , the base assembly 100 can be provided with an insertion opening 611, which can be used for inserting the insertion piece provided on the maintenance assembly. And after the insertion piece is inserted, the insertion piece can be locked by the locking piece 612. In another optional embodiment, the insertion piece can be provided on the base assembly, and the insertion opening can be provided on the maintenance assembly, and in addition, the locking piece can be provided on the base assembly or the maintenance assembly. In addition, by locking the base assembly and the maintenance assembly, it is convenient for the user to carry the base station. Moreover, when the dust removal assembly 200 and the cleaning assembly 300 share the assembly housing, the volume of the base can be effectively reduced.

[0055] BASE ASSEMBLY

[0056] Figure 6 and Figure 7 A front view and a perspective view of a base assembly 100 according to one embodiment are shown respectively. (Refer to...) Figure 6 and Figure 7 The base assembly 100 may include a base housing to form a space for accommodating at least a portion of the surface cleaning device. The base housing may include a first housing 111. Figure 6 The rear housing shown), the second housing 112 ( Figure 6 The left shell shown) and the third shell 113 ( Figure 6 (The right-side housing shown). The first housing 111, the second housing 112, and the third housing 113 form a semi-enclosed space and can be integrally molded. When the surface cleaning device is docked at the base assembly 100, at least a portion of the surface cleaning device enters the semi-enclosed space, wherein at least a portion of the rear side of the surface cleaning device equipped with the mopping component enters the semi-enclosed space. Further, the base assembly 100 may also include a fourth housing 114 ( Figure 7 (See the lower housing shown). The fourth housing 114 may include a support 115 and a ramp 116. The support 115 may be used to support at least a portion of the rear side of the surface cleaning device. The ramp 116 may provide a passage allowing the surface cleaning device to enter the semi-enclosed space.

[0057] The base assembly 100 may include a charging interface 120. When the surface cleaning device is positioned in the base assembly 100, the charging interface of the surface cleaning device can contact the charging interface 120 of the base assembly 100, and the surface cleaning device is charged through the charging interface 120 connected to an external power supply or other power supply device. The charging interface 120 is elastically extendable to ensure a tighter fit with the charging interface of the surface cleaning device. The charging interface 120 may be located on the inner side of the first housing 111, the second housing 112, or the third housing 113; in the figure, the charging interface 120 is shown located on the inner side of the first housing 111. Furthermore, the charging interface 120 is positioned at a predetermined height above the support 115 to prevent liquid from affecting charging during the cleaning of the surface cleaning device's mopping components.

[0058] According to an optional embodiment of this disclosure, the base assembly 100 may include a suction port 130, which can be connected to the suction port 15 of a surface cleaning device (e.g., ...). Figure 1The suction interface 130 is arranged on the inner side of the base assembly 100, for example, on the inner side of the first housing 111, or the second housing 112, or the third housing 113. In some embodiments, the suction interface 130 is arranged on the inner side of the third housing 113. Figure 6 and Figure 7 In some embodiments, the suction interface 130 is arranged on the inner side of the first housing 111. The suction interface 130 can extend outwardly from the surface of the inner side of the base assembly 100 by a predetermined length, which can be made of a flexible material. After the surface cleaning device docks with the base assembly 100, the suction interface 130 can be retracted to be inserted into the suction port of the surface cleaning device. Since the suction interface 130 is flexible, the suction interface 130 can bend during the insertion process to prevent damage to the surface cleaning device when the suction interface 130 is not aligned with the suction port of the surface cleaning device. Also, the flexibility of the suction interface 130 can ensure that the suction interface 130 is well inserted into the suction port of the surface cleaning device during the retraction process. The suction interface 130 can be in fluid communication with the cleaning assembly 300 via a conduit to provide cleaning liquid from the cleaning assembly 300 to the surface cleaning device for the purpose of cleaning liquid replenishment. In the present disclosure, it is preferred that the suction interface 130 and the liquid replenishment interface 140 are arranged on opposite sides of the charging interface 120, respectively.

[0059] Optionally, the base assembly 100 can include a liquid replenishment interface 140, which can be arranged on the inner side of the base assembly 100 and made of a flexible material that can bend when subjected to a certain pressure. The liquid replenishment interface 140 can be arranged on the inner side of the first housing 111, or the second housing 112, or the third housing 113. In some embodiments, the liquid replenishment interface 140 is arranged on the inner side of the third housing 113. Figure 6 and Figure 7 In some embodiments, the liquid replenishment interface 140 is arranged on the inner side of the first housing 111. The liquid replenishment interface 140 can extend outwardly from the surface of the inner side of the base assembly 100 by a predetermined length, which can be made of a flexible material. After the surface cleaning device docks with the base assembly 100, the liquid replenishment interface 140 can be retracted to be inserted into the liquid replenishment port of the surface cleaning device. Since the liquid replenishment interface 140 is flexible, the liquid replenishment interface 140 can bend during the insertion process to prevent damage to the surface cleaning device when the liquid replenishment interface 140 is not aligned with the liquid replenishment port of the surface cleaning device. Also, the flexibility of the liquid replenishment interface 140 can ensure that the liquid replenishment interface 140 is well inserted into the liquid replenishment port of the surface cleaning device during the retraction process. The liquid replenishment interface 140 can be in fluid communication with the cleaning assembly 300 via a conduit to provide cleaning liquid from the cleaning assembly 300 to the surface cleaning device for the purpose of cleaning liquid replenishment. In the present disclosure, it is preferred that the suction interface 130 and the liquid replenishment interface 140 are arranged on opposite sides of the charging interface 120, respectively.

[0060] In the present disclosure, the charging mode can be performed simultaneously with other maintenance modes, that is, the charging mode is initiated while other maintenance modes are being performed. For example, the charging mode is initiated while the self-emptying mode, the self-cleaning mode, and / or the liquid replenishment mode is being performed.

[0061] Optionally, the base assembly 100 may include guide wheels 150. When the surface cleaning device enters the base assembly 100, the guide wheels 150 may contact the side of the surface cleaning device and guide the surface cleaning device into the receiving space that accommodates the surface cleaning device. In this disclosure, there may be two guide wheels 150, and the two guide wheels 150 are respectively disposed on the inner sides of the second housing 112 and the third housing 113. The guide wheels 150 may be positioned on the outer side of the inner sides of the second housing 112 and the third housing 113, so that when the surface cleaning device enters the receiving space, the surface cleaning device first contacts the guide wheels 150, and the guide wheels 150 guide the surface cleaning device to stop in place in the receiving space.

[0062] A cleaning section may be provided on the support portion 115 of the base assembly 100. A recessed cleaning space that is closed on all four sides and the bottom surface may be formed on the support portion 115, in which recycled liquid can be stored. Figure 8 It shows according to Figure 6 The cross-sectional view obtained from section AA is shown. Figure 8 As shown, the cleaning section may include a liquid channel 1155 and a drain port 1152. The liquid channel 1155 can receive liquid from the cleaning assembly 300 through a pipe and guide the liquid to the cleaning section to clean the mop of the surface cleaning device. The drain port 1152 can provide the recovered liquid after cleaning to the cleaning assembly 300 through a pipe to realize the recovery function of the recovered liquid. A filter device may be provided at the location of the drain port 1152. In addition, the cleaning section may also include brushing members 1153. The number and position of the brushing members 1153 correspond to the number and position of the rotating members of the surface cleaning device. In this disclosure, there may be two brushing members 1153. When the rotating members rotate, the brushing members 1153 brush the mop, thereby achieving the self-cleaning function of the mop. A guide section 1156 may also be provided at the location of the cleaning section. When the surface cleaning device enters, the guide section 1156 can guide the surface cleaning device and also serve to support the surface cleaning device. For example, Figure 2 As shown, the rollers 16 of the surface cleaning device 10 can move along the guide portion 1156 and are supported.

[0063] Furthermore, the cleaning unit may also include a drying port 1154 for drying the mopping component of the surface cleaning device, and the drying port 1154 may be provided at a position corresponding to the mopping component. In this disclosure, the drying port 1154 is preferably provided in the fourth housing 114. Figure 7The drying port 1154 can occupy a certain area and can provide a hot air flow from the bottom of the mopping member, so that a better drying effect can be achieved. The drying port 1154 can be in gas communication with the cleaning assembly 300 through a pipe to receive the air flow from the cleaning assembly 300 and generate a hot air flow provided to the mopping member after being heated by the base assembly, thereby achieving the drying function of the mopping member. In the present disclosure, the drying port 1154 can be arranged at a certain height relative to the bottom of the washing space, and the number of drying ports can be one or more. The drying port is designed in a form extending in the radial direction of the mopping member so as to cover a larger area of the mopping member. For example, the drying port can be arranged in a long strip shape extending relative to the radial direction of the mopping member, or the number of drying ports can be arranged as multiple drying ports distributed along the radial direction of the mopping member. The arrangement of multiple drying ports can be arranged in the form of a fan-shaped arrangement.

[0064] Figure 9 and Figure 10 respectively show a front view and a perspective view of the base assembly 100 of another embodiment. Referring to Figure 9 and Figure 10 , the base assembly 100 can include a base housing to form a space to accommodate at least a portion of the surface cleaning device. The base housing can include a first housing 111 (a rear housing shown in Figure 9 ), a second housing 112 (a left housing shown in Figure 9 ) and a third housing 113 (a right housing shown in Figure 9 ). The first housing 111, the second housing 112 and the third housing 113 form a semi-enclosed space and can be integrally formed, at least a portion of the surface cleaning device enters the semi-enclosed space when the surface cleaning device is docked to the base assembly 100, wherein at least a portion of the rear side of the surface cleaning device provided with the mopping member enters the semi-enclosed space. Further, the base assembly 100 can further include a fourth housing 114 (a lower housing shown in Figure 10 ). The fourth housing 114 can include a support portion 115 and a ramp portion 116. The support portion 115 can be used to support at least a portion of the rear side of the surface cleaning device. The ramp portion 116 can provide a passage allowing the surface cleaning device to enter the semi-enclosed space.

[0065] The base assembly 100 can comprise a charging interface 120. When the surface cleaning device is docked in place in the base assembly 100, the charging interface provided on the surface cleaning device can be brought into contact with the charging interface 120 of the base assembly 100, and the surface cleaning device can be charged through the charging interface 120 connected with a power supply device such as an external power source. The charging interface 120 can be elastically flexible so as to better abut against the charging interface of the surface cleaning device. The charging interface 120 can be provided on the inner side of the first housing 111, the second housing 112 or the third housing 113, and in the drawings, the charging interface 120 is shown to be provided on the inner side of the first housing 111. The charging interface 120 can be provided at a predetermined height position above the support portion 115, so as to avoid the influence of liquid on charging when the mop of the surface cleaning device is cleaned.

[0066] According to an optional embodiment of the present disclosure, the base assembly 100 can comprise a suction interface 130, which can be connected with the suction port 15 (as shown in Figure 1 Fig. 1) of the surface cleaning device, so as to be in communication with the dust collection portion of the surface cleaning device, and thus in the case of using the dust discharging assembly 200 in the self-discharging mode, the garbage in the dust collection portion of the surface cleaning device can be sucked into the dust discharging assembly 200 through the suction interface 130 and the suction port 15. The outer side of the suction interface 130 can be provided with a suction sealing portion, which can surround the outer side of the suction interface 130 and can be made of an elastic material, so as to form a seal of the gas passage when the suction port 15 and the suction interface 130 are in abutment and form a pneumatic joint when the surface cleaning device is docked in place in the base assembly 100. Optionally, the suction interface 130 can be provided on the inner side of the base assembly 100, for example, on the inner side of the first housing 111, or the second housing 112 or the third housing 113. In Figure 9 and Figure 10 Fig. 1 shows that the suction interface 130 is provided on the inner side of the third housing 113.

[0067] Optionally, the base assembly 100 can comprise a liquid supplementing interface 140, which can be provided on the inner side of the base assembly 100, for example, on the inner side of the first housing 111, or the second housing 112 or the third housing 113. In Figure 9 and Figure 10The suction port 130 is shown disposed on the inner side of the first housing 111. The replenishment port 140 extends outwards by a predetermined length from the inner surface of the base assembly 100. It may be made of an elastic material and can bend under pressure. Thus, when the surface cleaning device is docked at the base assembly 100, the replenishment port 140 can extend and retract to insert into the replenishment port on the surface cleaning device. Because the replenishment port 140 is flexible, it can bend during insertion to prevent damage to the surface cleaning device if it is not aligned with the replenishment port of the surface cleaning device. Furthermore, its flexibility ensures proper insertion into the replenishment port during extension and retraction. The replenishment port 140 can be fluidly connected to the cleaning assembly 300 via a pipe to supply cleaning liquid from the cleaning assembly 300 to the surface cleaning device for replenishment. Preferably, the liquid replenishment port 140 and the suction port 130 are respectively located on both sides of the charging port 120.

[0068] In this disclosure, the charging mode can be performed simultaneously with other maintenance modes; that is, the charging mode can be activated while other maintenance modes are in operation. For example, the charging mode can be activated while the self-draining mode, self-cleaning mode, and / or liquid replenishment mode are in operation.

[0069] Optionally, the base assembly 100 may include guide wheels 150. When the surface cleaning device enters the base assembly 100, the guide wheels 150 may contact the side of the surface cleaning device and guide the surface cleaning device into the receiving space that accommodates the surface cleaning device. In this disclosure, there may be two guide wheels 150, and the two guide wheels 150 are respectively disposed on the inner sides of the second housing 112 and the third housing 113. The guide wheels 150 may be positioned on the outer side of the inner sides of the second housing 112 and the third housing 113, so that when the surface cleaning device enters the receiving space, the surface cleaning device first contacts the guide wheels 150, and the guide wheels 150 guide the surface cleaning device to stop in place in the receiving space.

[0070] A cleaning section may be provided on the support portion 115 of the base assembly 100. A recessed enclosed space that is closed on all four sides and the bottom surface may be formed on the support portion 115, in which the recycled liquid can be stored. Figure 11 It shows that according to Figure 9 The cross-sectional view obtained from section AA is shown. Figure 11As shown, the cleaning part can include a liquid outlet 1151 and a liquid discharge outlet 1152. The liquid outlet 1151 can be in fluid communication with the cleaning assembly 300, and the cleaning liquid provided by the cleaning assembly 300 can be sprayed from the liquid outlet 1151 so as to provide the cleaning liquid to the mop piece of the surface cleaning device. The liquid discharge outlet 1152 can provide the cleaned recovery liquid to the cleaning assembly 300 through a pipeline to achieve the recovery function of the recovery liquid. In addition, the cleaning part can also include a brush piece 1153, the number and position of which can correspond to the number and position of the rotating piece of the surface cleaning device. In the present disclosure, the number of the brush piece 1153 can be two, and when the rotating piece rotates, the brush piece 1153 brushes the mop piece installed on the rotating piece, thereby achieving the self-cleaning function of the mop piece. In addition, the cleaning part can also include a drying port 1154 for drying the mop piece, which can be arranged at a position corresponding to the mop piece and at a position at a predetermined height from the bottom surface of the support part 115. The drying port 1154 can be in gas communication with the cleaning assembly 300 through a pipeline, so as to receive drying gas from the cleaning assembly 300 and provide it to the mop piece, thereby achieving the drying function of the mop piece.

[0071] In addition, according to some embodiments of the present disclosure, a sealing structure 1161 can be provided on the slope part 116. The sealing structure 1161 can be recessed relative to the surface of the slope part 116, and the shape of the sealing structure 1161 is arranged to match the corresponding shape of the roller brush part of the surface cleaning device, so that when the surface cleaning device is parked on the base assembly 100, the sealing structure 1161 can airtightly seal the opening of the roller brush part. After sealing, the suction nozzle at the roller brush part for sucking debris is sealed. At this time, the first air flow path inside the surface cleaning device from the suction nozzle near the roller brush part to the dust collection part is blocked, and the second air flow path from the dust collection part of the surface cleaning device to the suction port 15 is opened. By closing the first air flow path, a larger suction force can be provided to better empty the debris and other garbage in the dust collection part. According to an optional embodiment of the present disclosure, an elastic baffle can be provided at a position of the base assembly 100 corresponding to the roller brush part, so that when the surface cleaning device returns to the base assembly 100, the elastic baffle can be popped up to close the suction nozzle of the roller brush part, etc.

[0072] <dust discharging assembly>

[0073] Figure 12An external schematic diagram of a dust extraction assembly according to an embodiment of the present disclosure is shown. The main function of the dust extraction assembly 200 is to suck up dust, debris, and other waste collected in the dust collection section of the surface cleaning device and to store the sucked-up waste. Furthermore, the dust extraction assembly 200 can be used in combination with the base assembly 100, and can also be used in conjunction with the cleaning assembly 300. For example, the dust extraction assembly 200 can be detachably connected to the upper surface of the base assembly 100, and after connection, the dust extraction assembly 200 can be integrally formed with the base assembly 100.

[0074] like Figure 12 As shown, the dust extraction assembly 200 may include a dust extraction assembly housing 210 and a recycling device 220. The dust extraction assembly housing 210 has an opening on its side, and the recycling device 220 can be detachably installed into the dust extraction assembly housing 210 through this opening. The detachable direction of the recycling device 220 relative to the dust extraction assembly housing 210 is generally parallel to the ground direction where the base station is installed. After the dust extraction assembly 200 with the recycling device 220 installed is assembled into the base assembly 100, the recycling device 220 and the suction port 130 of the base assembly 100 are fluidly connected through a pipe. This allows the waste in the dust collection section of the surface cleaning device to be sucked into the storage space of the recycling device 220, thereby emptying the dust collection section. Optionally, in this disclosure, the holding volume of the recycling device 220 may be set to at least three times the holding volume of the dust collection section of the surface cleaning device. When it is necessary to detach the recycling device 220 from the dust extraction assembly housing 210, the user can press it, and the recycling device 220 will pop out due to the elastic force.

[0075] Figure 13 It shows that it will be as follows Figure 12 A schematic diagram of the dust extraction assembly 200 after its outer casing has been removed. Figure 13 As shown, the dust removal assembly 200 may include a first suction source 230, which may be in the form of a fan and is disposed inside the dust removal assembly housing 210. In this disclosure, the first suction source 230 and the recycling device 220 may be disposed on the left and right sides of the dust removal assembly housing 210. The first suction source 230 generates a suction airflow, thereby creating a negative pressure state that allows dust and debris to enter the suction channel of the recycling device 220 from the surface cleaning device through the suction interface and corresponding pipe. For example, the suction channel may be connected to the pipe opening provided on the upper surface of the base assembly 100. Then, the dust and debris enter the internal space defined by the housing of the recycling device 220 through the suction inlet.

[0076] Figure 14A schematic diagram of the recycling device from another angle is shown. The recycling device 220 defines a receiving space for receiving and containing waste through its housing. The recycling device 220 may include a suction inlet 226, which can be connected to a suction port 130 via a pipe to allow dust, debris, and other waste to enter the interior of the recycling device 220. According to embodiments of this disclosure, such as... Figure 15 As shown, the recycling device 220 may further include a first dust collection outlet 227 and a second dust collection outlet 228. In an optional embodiment of this disclosure, the suction inlet 226 is located on one side of the housing of the recycling device 220, while the first dust collection outlet 227 and the second dust collection outlet 228 may be located on the other side of the housing of the recycling device 220. This one side and the other side can be two opposite sides of the housing of the recycling device 220. Furthermore, the suction inlet 226 and the first dust collection outlet 227 may be offset to the left relative to the centerline of the recycling device 220, and the second dust collection outlet 228 may be offset to the right relative to the centerline of the recycling device 220.

[0077] like Figure 15 As shown, the recycling device 220 may also include a switching unit 250. Figure 13 The diagram shows the switching unit 250 being installed into the housing of the recycling device 220. Figure 15 The diagram shows the switching unit 250 separated from the housing of the recovery device 220. The switching unit 250 can be a structure for switching air ducts and can be configured in a first state and a second state. In the first state, the switching unit 250 can open the first dust collection outlet 227 and close the second dust collection outlet 228; in the second state, the switching unit 250 can close the first dust collection outlet 227 and open the second dust collection outlet 228. In this disclosure, the first dust collection outlet 227 can be located close to the suction inlet 226. Optionally, the axis of the first dust collection outlet 227 can coincide with the axis of the suction inlet 226, or the axis of the first dust collection outlet 227 can be nearly coincident with the axis of the suction inlet 226, or the axis of the first dust collection outlet 227 can be parallel to the axis of the suction inlet 226 and located in a plane perpendicular to the bottom side of the recovery device 220. For example, the first dust collection outlet 227 can be located on the front side close to the suction inlet 226. Compared to the distance between the first dust collection outlet 227 and the suction inlet 226, the second dust collection outlet 228 can be located at a position far from the suction inlet 226. For example, the second dust collection outlet 228 and the suction inlet 226 can be arranged in a nearly diagonal manner, such as the central axis of the second dust collection outlet being slightly smaller than the length of the receiving space.

[0078] In one optional embodiment of the present disclosure, the accommodation space of the recycling device 220 can be provided with a cyclone separator or a dust bag. That is, the recycling device 220 can adopt an interchangeable structure of the cyclone separator and the dust bag. Figure 16 A schematic view showing the end cover portion 270 of the recycling device 220 removed to show the internal space of the recycling device 220 is shown. In Figure 16 A case where the cyclone separator is installed is shown in the middle, and a mounting structure 241 can be provided on the inner side wall of the recycling device 220, through which the cyclone separator 240 and the dust bag can be mounted into the accommodation space of the recycling device 220, and the inlet of the cyclone separator or the dust bag is in fluid communication with the suction inlet 226. In this way, dust and other garbage enters the cyclone separator or the dust bag through the suction inlet 226. As an example, the mounting structure 241 can be provided on both sides of the suction inlet 226, and when the cyclone separator is installed, the cyclone separator can be clamped to the mounting structure 241 on both sides, and when the dust bag is installed, the mounting plate provided on the dust bag can be inserted into the mounting structure 241. In the present disclosure, the first dust collection outlet 227 is used as the air outlet when the cyclone separator is used, and the second dust collection outlet 228 is used as the air outlet when the dust bag is used. When the cyclone separator is used, the first dust collection outlet 227 is selected to select an air duct close to the suction inlet 226, and dust and other garbage is thrown by the cyclone separator into the accommodation space formed by the housing of the recycling device 220, while air is discharged through the first dust collection outlet 227 which is in communication with the outlet of the cyclone separator. In the case of using the dust bag, the second dust collection outlet 228 is selected to select an air duct far from the suction inlet 226, and dust and other garbage is left in the dust bag provided in the accommodation space, while air is discharged through the second dust collection outlet 228. When the cyclone separator is used, the cyclone separator occupies a part of the space of the accommodation space, for example, it can occupy one third of the space, and the remaining space is used as a space for storing garbage. When the dust bag is used, by selecting the second dust collection outlet 228 to select a far air duct, the dust bag can be filled with the entire accommodation space when the air flows through the dust bag, so that the accommodation space can be fully utilized. As shown in the left side of the figure, Figure 15As shown, the switching part 250 can be provided with a first opening 251 and a second opening 252. The switching part 250 can slide relative to the outer side surface of the recycling device 220, so as to make one of the first dust collection outlet 227 and the second dust collection outlet 228 as the air exhaust outlet according to the use of the cyclone separator or the dust bag. When the cyclone separator is used, the switching part 250 slides to a first state, in which the first opening 251 of the switching part 250 is located at the position of the first dust collection outlet 227, so as to make the first dust collection outlet 227 as the air exhaust outlet of the recycling air flow, while the second dust collection outlet 228 is blocked by the switching part 250. When the dust bag is used, the switching part 250 slides to a second state, in which the second opening 252 of the switching part 250 is located at the position of the second dust collection outlet 228, so as to make the second dust collection outlet 228 as the air exhaust outlet of the recycling air flow, while the first dust collection outlet 227 is blocked by the switching part 250. It should be noted that, although the switching part provided with the first opening and the second opening is described above as an example. However, those skilled in the art should understand that the switching part can also take other forms, as long as it can block one of the first dust collection outlet and the second dust collection outlet and open the other during switching. For example, the switching part can be designed as a plate without openings, and its length is designed according to the distance between the first dust collection outlet and the second dust collection outlet, and the corresponding function can also be achieved.

[0079] Optionally, the recycling device 220 can include an exhaust part 223, which can be closed to form a closed garbage containing space, and can also be opened to facilitate the user to pour out the garbage (collected by the cyclone separator) in the containing space. In an optional embodiment, the exhaust part 223 can be in the form of an exhaust door, and one side of the exhaust door can rotate around the side shell of the recycling device 220 to be opened or closed. In addition, the other side shell of the recycling device 220 corresponding to the other side of the exhaust door can be provided with a locking part 224. As an example but not limited to, the locking part 224 can be in the form of a press button. The locking part 224 can lock the exhaust door to form a closed garbage containing space. And the user can operate the locking part 224 to make the exhaust part 223 be opened, so as to exhaust the dust and other garbage. In an optional example of the present disclosure, the exhaust part 223 can be arranged at one side of the recycling device 220, and the end cover part 270 can be arranged at the other side of the recycling device 220, wherein the one side and the other side are opposite sides, and the two sides are adjacent to the sides where the first dust collection outlet 227, the second dust collection outlet 228 and the suction inlet 226 are located.

[0080] Figure 17A cross-sectional view of the recycling device 220 is shown. In Figure 17 An automatic switching structure of the switching part 250 is shown in Figure 17 . The automatic switching structure can include a first spring 229. The first spring 229 can be disposed in an inner cavity formed by the housing of the recycling device 220. When the first spring 229 is compressed by a certain pressure, the first spring 229 is compressed, i.e. the switching part 250 can move towards the direction of the second dust collection outlet 228 (to the left). When the pressure of the first spring 229 is released, the switching part 250 can move towards the direction of the first dust collection outlet 227 (to the right). In this way, when the cyclone separator 240 needs to be installed into the recycling device 220, the structure of the cyclone separator 240 makes the switching part 250 move to the left, and after the cyclone separator 240 is installed in place, the switching part 250 remains at a position where the first opening 251 opens the first dust collection outlet 227 in the first state. When the cyclone separator 240 is removed, the tension of the first spring 229 makes the switching part 250 move to the right, so that in the case where the cyclone separator 240 is not installed, the position of the switching part 250 can move to the second state, in which the first opening 251 is closed, and the second dust collection outlet 228 is opened by the second opening 252. In this way, if the switching part 250 is switched manually, the user can avoid forgetting to switch the switching part when replacing the cyclone separator and the dust bag, resulting in the first state and the second state being incorrect. As shown in Figure 17 , a first recess 2201 can be provided inside the housing of the recycling device 220, and a corresponding clamping part 2401 is provided on the cyclone separator 240. After the cyclone separator 240 is installed into the mounting structure 241, the clamping part 2401 can be clamped into the first recess 2201 to fix the cyclone separator 240 to prevent the cyclone separator 240 from being displaced. When the cyclone separator 240 needs to be removed from the recycling device 220, the user can operate the clamping part 2401 to disengage the clamping part 2401 from the first recess 2201 to remove the cyclone separator 240.

[0081] According to one embodiment of the present disclosure, the recycling device 220 can be removed or installed inside the housing of the dust removal assembly 200 by pressing the clamping part. An embodiment of the self-locking structure will be described in detail below with reference to Figures 19 to 24 .

[0082] A first protruding part 2202 can be provided on the outer side of the recycling device 220, wherein the first protruding part 2202 is in a protruding form relative to other parts around the housing where the first protruding part 2202 is located. For example, the first protruding part 2202 can be flush with the housing of the recycling device 220.

[0083] The self-locking structure can further include a locking member 222. The locking member can include a body portion and an extension portion. The body portion can be disposed in the receiving member and move along the receiving member, and the extension portion extends from the body portion and can bend toward the body portion when subjected to pressure. The locking member 222 can be provided with a first recessed portion 2221, for example, on the extension portion, corresponding to the first protruding portion 2202. In the locked state, the first protruding portion 2202 can be inserted into the first recessed portion 2221 to lock the recycling device 220 in the housing of the dust discharging assembly 200. According to an optional embodiment, as shown in Figure 24 the locking member 222 can be further provided with a second recessed portion 2222 to enable elastic deformation of the extension portion or elastic deformation of the first recessed portion 2221. The locking member 222 can be disposed in the receiving member 280 and can slide relative to the receiving member 280 and be limited to move only in the left-right direction as shown in Figure 23 The receiving member 280 can be fastened to the housing of the dust discharging assembly 200.

[0084] The self-locking structure can include a return tension spring 2801 and a return rod 2802. One end of the return tension spring 2801 can be fixedly connected to the receiving member 280, and the other end can be fixed to the locking member 222. One end of the return rod 2802 can be disposed in the receiving member 280, and the other end (free end) can be disposed in the locking member 222. The return rod 2802 can be a return steel wire, for example, a rigid hook-shaped rod. The locking member 222 can be provided with an entry slot 2223. The free end of the return rod 2802 can slide in the entry slot 2223 and be guided by the wall surface of the entry slot 2223 into a locking slot position 2225. When the return rod 2802 is in the locking slot position 2225, the recycling device 220 is in the locked state. When unlocking from the locked state, the free end of the return rod 2802 can enter an exit slot 2224, and by the guidance of the wall surface of the exit slot, the free end of the return rod 2802 can enter a communication slot 2226. And when locking again, the free end of the return rod 2802 can enter the entry slot 2223 again until it is in the locking slot position 2225. The free end of the return rod 2802 is shown in the locking slot position 2225 and in the locked state in Figure 23

[0085] ​The locking and unlocking processes will be described in detail below. When locking, the user can press the end cover portion 270 after placing the recycling device 220 into the housing. The first protruding portion 2202 of the recycling device 220 is guided by the first guide surface 2227 of the locking member 222 into the first recessed portion 2221. At the same time, the free end of the reset lever 2802 can enter the entry slot 2223 along the communication slot 2226, and the free end of the reset lever 2802 is in the locking slot position 2225 by the guidance of the wall surface of the entry slot 2223, limiting the movement of the locking member, at this time, the reset tension spring 2801 is in a stretched state. In the unlocking process, the user can press the end cover portion 270 again, at this time, the free end of the reset lever 2802 will be out of contact with the locking slot position 2225, and enter the exit slot 2224, and then the free end of the reset lever 2802 enters the communication slot 2226 along the exit slot 2224. 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 position 2225, and there is no constraint action of the reset lever 2802), the locking member 222 moves together with the recycling device 220, and in the process of moving, the first guide surface 2227 of the locking member 222 can be in contact with the interference surface 2803 corresponding to the containing member 280. Because the containing member 280 has a downward extending inclined surface, the interference surface 2803 can extrude the first guide surface 2227 downward, so that the first protruding portion 2202 can be separated from the first recessed portion 2221, and the recycling device 220 can be popped out to the left side. The user can then pull out the recycling device 220.

[0086] Figure 26 An external view of a dust discharging assembly according to another embodiment of the present disclosure is shown. The main function of the dust discharging assembly 200 is to suck the garbage such as dust, debris, etc. collected in the dust collecting portion of the surface cleaning device, and store the sucked garbage. Also, the dust discharging assembly 200 can be used in combination with the base assembly 100, and can also be used in cooperation with the cleaning assembly 300. For example, the dust discharging assembly 200 can be detachably connected to the upper surface of the base assembly 100, and after connection, the dust discharging assembly 200 can be integrated with the base assembly 100.

[0087] As Figure 26As shown, the dust extraction assembly 200 may include a dust extraction assembly housing 210 and a recycling device 220. The dust extraction assembly housing 210 has an opening on its side, through which the recycling device 220 can be plugged into the dust extraction assembly housing 210. The pluggable direction of the recycling device 220 relative to the dust extraction assembly housing 210 is generally parallel to the ground direction where the base station is installed. After the dust extraction assembly 200 with the recycling device 220 installed is assembled to the base assembly 100, the recycling device 220 and the suction port 130 of the base assembly 100 are fluidly connected through a pipe. This allows waste in the dust collection section of the surface cleaning device to be sucked into the storage space of the recycling device 220, thereby emptying the dust collection section. Optionally, in this disclosure, the containing volume of the recycling device 220 may be set to be at least three times the containing volume of the dust collection section of the surface cleaning device.

[0088] Figure 27 It shows that it will be as follows Figure 26 This is a schematic diagram of the dust extraction assembly 200 after the side and bottom housings have been removed. Figure 27 As shown, the dust removal assembly 200 may further include a first suction source 230, which may be in the form of a fan and is disposed inside the dust removal assembly housing 210. In this disclosure, the first suction source 230 and the recovery device 220 may be disposed on the left and right sides of the dust removal assembly housing 210. The first suction source 230 generates a suction airflow, which causes dust and other debris to enter the suction channel 221 of the recovery device 220 from the surface cleaning device via the suction port 130 and a corresponding pipe. For example, the suction channel 221 may be connected to a pipe opening provided on the upper surface of the base assembly 100. Then, the dust and other debris enter the internal space defined by the housing of the recovery device 220 through the suction inlet.

[0089] Figure 28 and Figure 29 Schematic diagrams of the recycling device from different angles are shown. The recycling device 220 defines a receiving space for receiving and accommodating waste through its housing. The recycling device 220 may include a handle 260 disposed on one side of the recycling device 220. The user can use the handle 260 to insert the recycling device 220 into or remove it from the dust extraction assembly housing 210.

[0090] Figures 30 to 32A schematic view of the handle portion 260 is shown. As shown, according to one alternative embodiment, the handle portion 260 can include a first portion 261, a second portion 262 and a third portion 263. The second portion 262 and the third portion 263 can be fitted together and the first portion 261 can be located between the second portion 262 and the third portion 263. The first portion 261 can include a first part and a second part, and the two independent parts can include a first slope 2611 and a second slope 2612, respectively. When the recycling device 220 is inserted into the dust extraction assembly housing 210, the first slope 2611 and the second slope 2612 can abut against the housing of the dust extraction assembly housing 210, and because of the pushing force applied by the user, the first slope 2611 and the second slope 2612 will retract, allowing the recycling device 220 to be fully inserted into the dust extraction assembly housing 210. After full insertion, the first slope 2611 and the second slope 2612 will rebound and extend into the corresponding mounting holes of the dust extraction assembly housing 210, thereby securing the dust extraction assembly housing 210. The first part of the first portion 261 can be provided with a third slope 2613, and the second part of the first portion 261 can be provided with a fourth slope 2614. Correspondingly, the second portion 262 can be provided with a fifth slope 2621 and a sixth slope 2622. The third slope 2613 and the fifth slope 2621 cooperate with each other, and the fourth slope 2614 and the sixth slope 2622 cooperate with each other. Thus, when the user pinches the second portion 262, the fifth slope 2621 of the second portion 262 can slide into the third slope 2613, and the cooperation between the third slope 2613 and the fifth slope 2621 causes the first slope 2611 to disengage from the corresponding mounting hole of the dust extraction assembly housing 210; the sixth slope 2622 of the second portion 262 can slide into the fourth slope 2614, and the cooperation between the fourth slope 2614 and the sixth slope 2622 causes the second slope 2612 to disengage from the corresponding mounting hole of the dust extraction assembly housing 210, so that the user can remove the recycling device 220 from the dust extraction assembly 200. The third portion 263 can be used to carry the first portion 261, for example, to provide guidance for the movement of the first portion 261, etc. In addition, a resilient member can be provided between the second portion 262 and the third portion 263, so that the user can restore the second portion 262 to its original position relative to the third portion 263 after pinching.

[0091] Optionally, the recycling device 220 may include a discharge section 223, which can be closed to form a closed waste-containing space, or opened to allow a user to empty the waste from the space. In one optional embodiment, the discharge section 223 may be in the form of a discharge door, and one side of the discharge door may be rotatable around one side of the housing of the recycling device 220 to be opened or closed. Additionally, a locking member 224 may be provided on the other side of the housing of the recycling device 220 corresponding to the discharge door. As an example, but not limited to, the locking member 224 may be in the form of a push-button. The locking member 224 can lock the discharge door to form a closed waste-containing space. The user can operate the locking member 224 to open the discharge section 223 for discharging dust and other waste. In an optional example of this disclosure, the discharge section 223 may be located on one side of the recycling device 220, while the handle 260 may be located on the other side of the recycling device 220, wherein the one side and the other side are opposite sides.

[0092] Optionally, the recycling device 220 may include a maintenance cover 225. Figure 33 A schematic diagram is shown with the maintenance cover 225 removed. In an alternative embodiment of this disclosure, the receiving space of the recycling device 220 may be provided with a cyclone separator or a dust bag.

The cyclone separator 240 can be mounted into the receiving space of the recycling device 220 via a mounting structure 241. The mounting structure 241 can be disposed on the housing forming the suction channel 221. Both the cyclone separator and the dust bag can be detachably mounted into the receiving space via the mounting structure 241. The inlets of the cyclone separator or the dust bag are connected to... Figure 34 The suction inlets 226 shown are aligned to achieve fluid communication. Dust and debris then enter the cyclone separator or dust bag through the suction inlets 226. As an example, mounting structures 241 can be provided on opposite sides of the suction inlets 226, and when installing the cyclone separator, it can be snapped into the mounting structure 241; when installing the dust bag, the mounting plate for the dust bag can be inserted into the mounting structure 241.

[0093] In addition, to better utilize the cyclone separator or dust bag, a switching unit 250 is provided in an optional embodiment of this disclosure. When using a cyclone separator, the switching unit 250 can be set to a first state, while when using a dust bag, the switching unit can be set to a second state.

[0094] In the present disclosure, preferably, the discharge portion 223 can be provided at a first side (left side) of the recycling device 220, the handle portion 260 can be provided at a second side (right side) of the recycling device 220, the maintenance cover portion 225 can be provided at a third side (upper side) of the recycling device 220, the inlet of the suction passage 221 can be provided at a fourth side (lower side) of the recycling device 220 and can be provided at a position adjacent to a fifth side (rear side) of the recycling device 220, and the switching portion 250 can be provided at a sixth side (front side) of the recycling device 220.

[0095] The switching portion 250 can be a structure for switching the air duct. In Figure 35 a schematic view showing the switching portion removed is shown. Figure 36 a schematic view showing the switching portion provided in a first state is shown. Figure 37 a schematic view showing the switching portion provided in a second state is shown.

For example Figure 37 shown, the first dust collection outlet 227 can be provided at a position closer to the suction inlet 226, and the second dust collection outlet 228 can be provided at a position farther from the suction inlet 226. The first dust collection outlet 227 and the second dust collection outlet 228 can be provided at a predetermined distance apart. In the present disclosure, preferably, an axis of the first dust collection outlet 227 can coincide with an axis of the suction inlet 226, for example, the first dust collection outlet 227 can be provided at a position closest to the suction inlet 226 on the front side.

[0097] In the present disclosure, the first dust collection outlet 227 is used as the air outlet when the cyclone separator is used, and the second dust collection outlet 228 is used as the air outlet when the dust bag is used. When the cyclone separator is used, the first dust collection outlet 227 is selected to select the air duct close to the suction inlet 226, and the dust and other garbage are thrown into the containing space by the cyclone separator, and the air is discharged through the first dust collection outlet 227 which is in connection with the outlet of the cyclone separator. In the case of using the dust bag, the second dust collection outlet 228 is selected to select the air duct far away from the suction inlet 226, and the dust and other garbage are left in the dust bag arranged in the containing space, and the air is discharged through the second dust collection outlet 228. When the cyclone separator is used, the cyclone separator occupies a part of the space of the containing space, for example, it can occupy one third of the space, and the remaining space is used as a space for storing garbage. When the dust bag is used, by selecting the second dust collection outlet 228 to select the air duct far away, the dust bag can be filled with the entire containing space when the air flow passes through the dust bag, so that the containing space can be fully utilized.

[0098] Figure 38 A schematic view of the switching part 250 is shown according to an embodiment of the present disclosure. The switching part 250 can be provided with a first opening 251 and a second opening 252. The switching part 250 can slide relative to the front side of the recycling device 220, for example, when the recycling device 220 is taken out, the user can manually dial the switching part 250, so that one of the first dust collection outlet 227 and the second dust collection outlet 228 is used as the air discharge outlet according to the use of the cyclone separator or the dust bag. When the cyclone separator is used, the switching part 250 slides to the first state as shown in Figure 35 , in which the first opening 251 of the switching part 250 is located at the position of the first dust collection outlet 227, so that the first dust collection outlet 227 is used as the air discharge outlet of the recycling air flow, and the second dust collection outlet 228 is blocked by the switching part 250. In the case of using the dust bag, the switching part 250 slides to the second state as shown in Figure 36 , in which the second opening 252 of the switching part 250 is located at the position of the second dust collection outlet 228, so that the second dust collection outlet 228 is used as the air discharge outlet of the recycling air flow, and the first dust collection outlet 227 is blocked by the switching part 250.

[0099] Optionally, as shown in Figure 39 , a blocking part 2281 can be arranged at the position of the second dust collection outlet 228 or near the second dust collection outlet 228, wherein the blocking part 2281 has a preset inclined angle, and the inclined angle is arranged to extend away from the first dust collection outlet 227. The blocking part 2281 can prevent the dust bag from protruding outward from the second dust collection outlet 228 and blocking the air flow discharged from the second dust collection outlet 228.

[0100] Accordingly, according to the above-described design of the present disclosure, when the cyclone separator is used, the first dust collection outlet 227 is used, the air duct distance is short, and the dust and other garbage is thrown to the left containing space, and it is convenient to dump the garbage from the left. When the dust bag is used, the second dust collection outlet 228 is used, the air flow flows from the suction inlet 226 to the second dust collection outlet 228, the air duct distance is long, so that the dust bag is fully unfolded in the containing space, and the containing space can be fully utilized.

Inside the cleaning liquid storage part 350, a first float part 356 can be provided, which is arranged near the first bottom wall 355. The first float part 356 can be provided with a magnet or formed of a magnetic material. When there is no cleaning liquid in the cleaning liquid storage part 350, the first float part 356 can fall down, for example, can contact the first bottom wall 355, and when there is cleaning liquid in the cleaning liquid storage part 350, the first float part 356 can rise due to the liquid buoyancy. Herein, the stroke of the first float part 356 can be set to a predetermined distance, for example, the predetermined distance is a predetermined height from the first bottom wall 355. In addition, in order to limit the stroke of the first float part 356, a first stroke limiting part 357 can be provided on the periphery of the first float part 356. In addition, in order to detect the position of the first float part 356, a magnetic field detection part such as a Hall sensor can be provided at a corresponding position outside the cleaning liquid storage part 350, and in addition, the user can be prompted by the display control part 330 according to the detection information of the magnetic field detection part. In the present disclosure, the function of the first float part 356 can be only used to detect whether there is cleaning liquid in the cleaning liquid storage part 350, and therefore the stroke of the first float part 356 can be set to only a short distance that can be moved relative to the first bottom wall 355. In addition, a first filter part 358 can be provided inside the cleaning liquid storage part 350, which is arranged at a position near the first bottom wall 355. The first filter part 358 is used to filter the cleaning liquid provided by the cleaning liquid storage part 350.

[0107] Figure 43 A schematic view of a recovery liquid storage part according to one embodiment of the present disclosure is shown. The shape of the recovery liquid storage part 360 can be a cylinder, a square barrel, or any suitable shape, and can include a second side wall, a second bottom wall, and a second cover part. The second cover part 361 is provided with a second handle part 362, which can be used to take out the recovery liquid storage part 360 from the cleaning assembly 300 after opening the upper housing 320 of the cleaning assembly 300, and pour the recovery liquid in the recovery liquid storage part 360 by opening the second cover part 361. In one optional embodiment of the present disclosure, the second cover part 361 can be locked in a closed state by a second locking part 363 such as a buckle, and the second cover part 361 can be opened by unlocking the second locking part 363.

[0108] Figure 44 A schematic view of the recovery liquid storage part after the second cover part is removed is shown. As shown, the second side wall 364 and the second bottom wall 365 form a space for storing a recovery liquid such as waste water. Inside the recovery liquid storage part 360, a second float part 366 can be provided, which is arranged near the second bottom wall 365. The second float part 366 can be provided with a magnet or formed of a magnetic material. When there is no recovery liquid in the recovery liquid storage part 360, the second float part 366 can fall down, for example, can contact the second bottom wall 365, and when there is recovery liquid in the recovery liquid storage part 360, the second float part 366 can rise due to the liquid buoyancy. Herein, the stroke of the second float part 366 can be set to a predetermined distance, for example, the predetermined distance is a predetermined height from the second bottom wall 365. In addition, in order to limit the stroke of the second float part 366, a second stroke limiting part 367 can be provided on the periphery of the second float part 366. In addition, in order to detect the position of the second float part 366, a magnetic field detection part such as a Hall sensor can be provided at a corresponding position outside the recovery liquid storage part 360, and in addition, the user can be prompted by the display control part 330 according to the detection information of the magnetic field detection part. In the present disclosure, the function of the second float part 366 can be only used to detect whether there is recovery liquid in the recovery liquid storage part 360, and therefore the stroke of the second float part 366 can be set to only a short distance that can be moved relative to the second bottom wall 365. In addition, a second filter part 368 can be provided inside the recovery liquid storage part 360, which is arranged at a position near the second bottom wall 365. The second filter part 368 is used to filter the recovery liquid provided by the recovery liquid storage part 360. Figure 44As shown, the second side wall 364 and the second bottom wall 365 form a space for storing the recovered liquid. Inside the recovered liquid storage portion 360, a second float portion 366 can be provided, which is arranged at a position close to the second cover portion 361. The second float portion 366 can be provided with a magnet or formed of a magnetic material. When the recovered liquid in the recovered liquid storage portion 360 reaches a liquid level threshold, the second float portion 366 can be lifted by the buoyancy of the recovered liquid. In addition, a blocking portion 367 can also be included, which is connected with the second float portion 366 so as to be linked with each other, specifically, when the position of the second float portion 366 is raised, the position of the blocking portion 367 is lowered, so that when the recovered liquid reaches the liquid level threshold, the exhaust port 368 of the recovered liquid storage portion 360 can be blocked by the blocking portion 367, so as to prevent the recovered liquid from continuing to enter the recovered liquid storage portion 360 and from overflowing from the recovered liquid storage portion 360. When the position of the second float portion 366 is lowered, the position of the blocking portion 367 is raised, so that the blocking portion 367 will not block the exhaust port 368. In addition, the second float portion 366 can be suspended at a predetermined height through the connecting portion therebetween and the blocking portion 367. In order to detect the position of the second float portion 366, a magnetic field detection portion such as a Hall sensor can be provided at a corresponding position outside the recovered liquid storage portion 360. In the present disclosure, the function of the second float portion 366 can be only arranged to detect whether the recovered liquid in the recovered liquid storage portion 360 reaches the liquid level threshold, and when the liquid level threshold is reached, the user can be prompted through the display of the display control portion 330. The recovered liquid storage portion 360 is provided with a liquid inlet 369, through which the recovered liquid can enter the inside of the recovered liquid storage portion 360. Specifically, a vacuum pump can be arranged downstream of the exhaust port 368, and the inside of the recovered liquid storage portion 360 is formed in a vacuum state through the suction of the vacuum pump, so that the recovered liquid can enter the inside of the recovered liquid storage portion 360 through the liquid inlet 369 according to the vacuum state. When the recovered liquid reaches the liquid level threshold, the blocking portion 367 blocks the exhaust port 368, so that the recovered liquid cannot continue to enter the recovered liquid storage portion 360 through the liquid inlet 369.

[0109] According to an optional embodiment of the present disclosure, a sterilization and disinfection device can be arranged relative to the recovered liquid storage portion 360. Figure 45 A schematic view of the sterilization and disinfection device arranged in the recovered liquid storage portion 360 is shown. The sterilization and disinfection device can include a light source, which is arranged to emit light in a direction towards the recovered liquid storage portion 360. Figure 28The light source is in the form of a lamp tube 381, which can be arranged near the bottom end of the recycled liquid storage portion 360 or near the side wall of the recycled liquid storage portion 360. The number of lamp tubes 381 can be one or more, which are used to emit sterilization light such as ultraviolet light to sterilize the liquid contained in the recycled liquid storage portion 360. A light guide portion 382 can be arranged corresponding to the lamp tube 381. When the lamp tube 381 is arranged near the bottom end of the recycled liquid storage portion 360, the light guide portion 382 can be arranged on the inner bottom end of the recycled liquid storage portion 360 and extend along the longitudinal direction of the recycled liquid storage portion 360 to guide the light to be uniformly distributed in the recycled liquid storage portion 360. When the lamp tube 381 is arranged near the outer side of the recycled liquid storage portion 360, the light guide portion 382 can be arranged on the inner side wall of the recycled liquid storage portion 360 and extend along the transverse direction of the recycled liquid storage portion 360 to guide the light to be uniformly distributed in the recycled liquid storage portion 360, thereby improving the coverage of sterilization. The number of light guide portions 382 can be one or more. When the number of light guide portions 382 is one, the light guide portion 382 is installed at the center of the bottom end or the side wall of the recycled liquid storage portion 360. When the number of light guide portions 382 is more than one, the light guide portions 382 are symmetrically or uniformly installed at the center of the bottom end or the side wall of the recycled liquid storage portion 360. Symmetrical or uniform installation helps the light guide portion 382 to guide the light to be uniformly distributed, thereby effectively improving the coverage of sterilization.

[0110] The light guide part 382 can be one or more of a cylinder, a prism (triangular prism, quadrangular prism, etc.), a square cylinder, etc., and the light guide part 382 is integrally formed with the recycled liquid storage part 360 or the light guide part 382 is detachably mounted to the recycled liquid storage part 360. In the case where the light guide part 382 is detachably mounted to the recycled liquid storage part 360, a mounting structure for mounting the light guide part 382 is provided on the recycled liquid storage part 360. The recycled liquid storage part 360 has a mounting post, and the light guide part 382 has a mounting cavity provided at one end of the light guide part 382 or the light guide part 382 is a hollow structure and the hollow structure at one end of the light guide part 382 serves as the mounting cavity, the mounting cavity can be placed on the mounting post, and the mounting post and the mounting cavity are used in cooperation to mount the light guide part 382 to the recycled liquid storage part 360, the end of the light guide part 382 connected to the recycled liquid storage part 360 is sealed, and the end of the light guide part 382 not connected also needs to be sealed to prevent sewage from entering the light guide part 382 and being difficult to clean. A connecting piece is provided in the recycled liquid storage part 360, and the connecting piece connects the light guide part 382 and the side wall of the recycled liquid storage part 360 to fix the light guide part 382. The connecting piece can be a connecting rod or a connecting arm, and the connecting piece is made of a rigid or flexible thin material that is not easy to be contaminated and does not block ultraviolet light. The material of the light guide structure can be ABS, AS (SAN), PC, PMMA, etc., and the material of the light guide structure has high light transmittance, and the bottom end of the recycled liquid storage part 360 connected to the light guide structure can be made of a material with high light transmittance.

[0111] In the above embodiment, the light source is in the form of a lamp tube, but it can also be in the form of a lamp bead or the like. For example, in the form of a lamp bead, the lamp bead is mounted on a mounting plate and is arranged near the bottom end of the recycled liquid storage part 360, and the lower surface of the recycled liquid storage part 360 has a recess recessed into the recycled liquid storage part 360, the recess protrudes inwardly relative to the lower inner surface to form a protrusion protruding relative to the lower inner surface, and the light guide part 382 is provided with a mounting cavity, and the mounting cavity is nested into the protrusion to mount the light guide part 382 to the recycled liquid storage part 360.

The mixed liquid in the mixing chamber 370 can be provided to the base assembly 100 and / or the surface cleaning apparatus through a third conduit 431. For example, an inlet interface 375 can be provided on the housing of the mixing chamber 370 to receive the cleaning agent and the cleaning liquid, and an outlet interface 376 can be provided to provide the mixed liquid to the third conduit. However, it should be understood by those skilled in the art that the three-way valve as described above can not be used, and the mixing chamber 370 can be provided with separate inlets to receive the cleaning agent and the cleaning liquid, respectively. Figure 47

[0115] In the present disclosure, the inlet interface 375 can be provided corresponding to the first impeller portion 371. As shown, the inlet interface 375 can be provided on the housing of the mixing chamber 370 to receive the cleaning agent and the cleaning liquid. The inlet interface 375 can be provided on the housing of the mixing chamber 370 to receive the cleaning agent and the cleaning liquid. The inlet interface 375 can be provided on the housing of the mixing chamber 370 to receive the cleaning agent and the cleaning liquid. The inlet interface 375 can be provided on the housing of the mixing chamber 370 to receive the cleaning agent and the cleaning liquid. Figure 49 ​As shown in FIG. 3B (showing internal structure), the first impeller part 371 can include a plurality of first blades, wherein the blade surface of the first blade can be arranged as a circular arc surface, to bear the impact force and / or gravity of the liquid entering from the inlet interface 375, so that the first impeller part 371 can be rotated by the liquid from the inlet interface 375. The first impeller part 371 can be fixedly sleeved on the transmission shaft 373, and the second impeller part 372 is also fixedly sleeved on the transmission shaft 373. When the first impeller part 371 rotates, it will drive the transmission shaft 373 to rotate, so that the second impeller part 372 also rotates. In the present disclosure, the first impeller part 371 can be regarded as a rotating driving part, and the second impeller part 372 can be regarded as a rotating driven part. Through the rotation of the second impeller part 372, the cleaning liquid such as cleaning water and the cleaning agent such as detergent entering the mixing chamber 370 are mixed, so that the second impeller part 372 serves as a stirring device. The mixed liquid can be provided outside through the third pipeline 431 arranged near the bottom of the mixing chamber 370 after being mixed sufficiently.

[0116] The transmission shaft 373 can be supported on the top surface of the mixing chamber 370 through the first bearing 3731, and supported on the bottom surface of the mixing chamber 370 through the second bearing 3732, so as to effectively reduce the rotation resistance and avoid noise. The first impeller part 371 and the second impeller part 372 can be fixed to the transmission shaft 373 through axial fastening devices and radial fastening devices, respectively. As an example, the first impeller part 371 can be fixed on the transmission shaft 373 through the first axial snap spring 3733 and the first radial snap groove 3734, and the second impeller part 372 can be fixed on the transmission shaft 373 through the second axial snap spring 3735 and the second radial snap groove 3736. Through this fixing mode, the problems of radial and axial jumping of the first impeller part 371 and the second impeller part 372 during work can be effectively prevented. Of course, those skilled in the art should understand that other forms of fixing mode can also be adopted. According to the internal arrangement mode of the mixing chamber of the present disclosure, many advantages such as compactness, low noise, low cost, etc. can be achieved.

[0117] In the present disclosure, the impact direction of the fluid F entering the mixing chamber 370 from the inlet interface 375 can be the radial direction of the blade, for example, see Figure 50 and Figure 51Optionally, the force point of the fluid impact force on each blade of the first impeller portion 371 can be located at the middle portion of the blade, so that the first impeller portion 371 can be well rotated by the fluid impact, and the impact direction of the fluid can be substantially the radial direction of the blade. Each blade of the first impeller portion 371 is arc-shaped, and the axial included angle of the arc-shaped blade can 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 (here, up and down refer to the state of the arc-shaped blade in the working state), the angle of the arc-shaped blade gradually decreases relative to the axial direction of the transmission shaft. In this way, the arc-shaped blade has a predetermined inclination angle relative to the direction perpendicular to the axial direction of the transmission shaft 373. And each blade of the first impeller portion 371 is inclined along the rotation direction from the lower portion of the blade to the upper portion of the blade.

[0118] In the present disclosure, in addition to arranging the inlet interface 375 on the upper side wall of the mixing chamber 370, the inlet interface 375 can also be arranged at the top of the mixing chamber 370, and the entering fluid can align the blades to rotate the first impeller portion 371 by the kinetic energy and potential energy of the fluid, for example, in the manner described above.

[0119] Each blade of the second impeller portion 372 is arc-shaped, and the axial included angle of the arc-shaped blade can range from 5° to 85°. For example, from the upper portion of the arc-shaped blade to the lower portion of the arc-shaped blade (here, up and down refer to the state of the arc-shaped blade in the working state), the angle of the arc-shaped blade gradually decreases relative to the axial direction of the transmission shaft. In this way, the arc-shaped blade has a predetermined inclination angle relative to the direction perpendicular to the axial direction of the transmission 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 second impeller portion 372 as a stirring device can more fully stir the cleaning agent and the cleaning liquid.

[0120] According to the mixing chamber 370 of the present disclosure, under the condition of a certain space, the kinetic energy and potential energy of the entering cleaning liquid can be fully utilized to complete the stirring and mixing of the mixed liquid, thereby realizing various advantages such as low noise and low cost. Therefore, in the mixing chamber of the present disclosure, a good stirring effect can be achieved without using a motor and a speed reduction device.

[0121] In addition, in the second maintenance assembly 300, an airflow generating device can also be provided, wherein the airflow generating device can include a first airflow generating device 510 and a second airflow generating device 520. The airflow provided by the first airflow generating device 510 is delivered to the first inlet 512 of the base assembly 100 via the first airflow port 511, and a heating device such as a PTC heater can be provided near the first inlet 512 to heat the airflow to form a hot airflow for drying treatment. The hot 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 such as a PTC heater can be provided near the second inlet 522 to heat the airflow to form a hot airflow for drying treatment. As an optional embodiment, a liquid level detection device 374 can also be provided in the mixing bin 370, wherein the liquid level detection device 374 can be used to detect the height of the liquid level in the mixing bin 370. The liquid level detection device 374 can be used to detect the lower liquid level threshold and the higher liquid level threshold in the mixing bin 370. The liquid level detection device 374 can be formed by one detector, or can be formed by two or more detectors to detect the lower liquid level threshold and the higher liquid level threshold. Here, three liquid level detection devices are shown, wherein the first liquid level detection device can be used to detect the lower liquid level threshold, the second liquid level detection device can be used to detect the higher liquid level threshold, and the third liquid level detection device can be used in cooperation with the first liquid level detection device and the second liquid level detection device respectively for verification, etc.

[0122] According to one example of the present disclosure, the cleaning agent storage portion 340 is detachable with respect to the cleaning assembly 300, and the user can replace the cleaning agent storage portion 340. As shown in FIG. 6, the cleaning agent storage portion 340 is provided with a first connecting portion 341 and a second connecting portion 342, and the first connecting portion 341 and the second connecting portion 342 are respectively connected to the first connecting portion 311 and the second connecting portion 312 of the cleaning assembly 300. Figure 52As shown in FIG. 6, the housing 3410 of the cleaning assembly 300 can be provided with an opening (e.g., provided at the upper portion of the cleaning assembly 300) for insertion of the cleaning agent storage 340. In order to allow locking and unlocking of the cleaning agent storage 340, a reset latch 3420 can also be included as an embodiment, wherein locking and unlocking of the cleaning agent storage 340 is achieved by cooperation of the reset latch 3420 with the locking structure of the cleaning agent storage 340 described below. In addition, the user can insert or eject the cleaning agent storage 340 by pressing the cleaning agent storage 340, and a reset spring 3430 can also be included as an embodiment, which can be used at least to eject the cleaning agent storage 340. In addition, the reset spring 3430 can be in direct contact with the reset latch 3420, and a ejector 3440 can be provided, which can be arranged between the reset spring 3430 and the reset latch 3420, so that the reset latch 3420 can be lifted by the elastic force of the reset spring 3430 when the cleaning agent storage 340 is in the unlocked state, for example, by the elastic force applied to the ejector 3440. In the present disclosure, an eject spring 3450 can also be provided, which can cooperate with a lifting member 3460 to eject the cleaning agent storage 340 from the housing 3410.

[0123] The self-locking and rebounding structure of the cleaning agent storage 340 of an embodiment of the present disclosure will be described in detail below.

[0124] Figure 52 As shown in FIG. 6, the housing 3410 of the cleaning assembly 300 can be provided with an opening (e.g., provided at the upper portion of the cleaning assembly 300) for insertion of the cleaning agent storage 340. In order to allow locking and unlocking of the cleaning agent storage 340, a reset latch 3420 can also be included as an embodiment, wherein locking and unlocking of the cleaning agent storage 340 is achieved by cooperation of the reset latch 3420 with the locking structure of the cleaning agent storage 340 described below. In addition, the user can insert or eject the cleaning agent storage 340 by pressing the cleaning agent storage 340, and a reset spring 3430 can also be included as an embodiment, which can be used at least to eject the cleaning agent storage 340. In addition, the reset spring 3430 can be in direct contact with the reset latch 3420, and a ejector 3440 can be provided, which can be arranged between the reset spring 3430 and the reset latch 3420, so that the reset latch 3420 can be lifted by the elastic force of the reset spring 3430 when the cleaning agent storage 340 is in the unlocked state, for example, by the elastic force applied to the ejector 3440. In the present disclosure, an eject spring 3450 can also be provided, which can cooperate with a lifting member 3460 to eject the cleaning agent storage 340 from the housing 3410. Figure 53 As shown in FIG. 6, the structure of the outlet end 3401 can be provided with a guide channel and a groove, which can cooperate with the protruding portion 3421 of the reset latch 3420 to switch between the locked state and the unlocked state. The outlet end 3401 can include a notch 3402, which can be entered by the protruding portion 3421.

[0125] As shown in FIG. 6, the structure of the outlet end 3401 can be provided with a guide channel and a groove, which can cooperate with the protruding portion 3421 of the reset latch 3420 to switch between the locked state and the unlocked state. The outlet end 3401 can include a notch 3402, which can be entered by the protruding portion 3421. Figure 54As shown, the outlet end 3401 can further include a first guiding passage 3403 and a limiting groove 3404. The first guiding passage 3403 is used to connect the notch 3402 and the limiting groove 3404, so that when the cleaning agent storage portion 340 is pressed, the protrusion 3421 entering from the notch 3402 will slide along the first guiding passage 3403 into the limiting groove 3404, for example, can slide along the guiding wall of the first guiding passage 3403 into the limiting groove 3404. The height of the limiting groove 3404 is higher than the height of the notch 3402, and the first guiding passage 3403 extends upward from the notch 3402 to the limiting groove 3404, which can be arc-shaped and can include two side walls to form a passage. The first side wall 3403a can start from a position above the notch 3402 (spaced a certain distance from the notch 3402, one end of the first side wall 3403a can deviate from the center position of the notch 3402, for example, deviate in a direction away from the limiting groove 3404), and the end point is set to the limiting groove 3404. The second side wall 3403b starts from the notch 3402, and the end point can be set below the limiting groove 3404 (spaced a certain distance from the limiting groove 3404). The third side wall 3404a of the groove corresponding to the first side wall 3403a can be set as a straight face (perpendicular to the horizontal plane where the boundary of the notch is located), so as to limit the position of the protrusion 3421. It should be noted that during the process of the protrusion 3421 sliding into the limiting groove 3404, the cleaning agent storage portion 340 is fixed, and the reset lock 3420 is rotating.

[0126] The outlet end 3401 can further include a second guide channel 3405, which includes a fourth side wall 3405a, a fifth side wall 3405b, and a sixth side wall 3405c, and is generally V-shaped. A locking groove 3405d is provided between the fourth side wall 3405a and the fifth side wall 3405b. When the protrusion enters the locking groove, the protrusion is abutted in the locking groove due to the elastic force of a reset spring described below, so that the cleaning agent storage portion 340 is locked. The outlet end 3401 can further include a non-limiting groove 3406, in which one end of the fourth side wall 3405a is connected to one end of the second side wall 3403b, and the other end of the fourth side wall 3405a is connected to one end of the fifth side wall 3405b. The height at which one end of the fourth side wall 3405a is located is higher than the height at which the other end of the fourth side wall 3405a is located. The height at which the other end of the fifth side wall 3405b is located is higher than the height at which one end of the fifth side wall 3405b is located. One end of the sixth side wall 3405c is connected to one end of the third side wall 3404a, and the other end extends to the non-limiting groove 3406. The height at which one end of the sixth side wall 3405c is located is lower than the height at which the other end of the sixth side wall 3405c is located. When the protrusion 3421 is located in the limiting groove 3404 and the cleaning agent storage portion 340 is in the locked state, if the cleaning agent storage portion 340 is pressed again, the cleaning agent storage portion 340 will move downward together with the reset lock 3420. When the user finishes pressing, the protrusion 3421 will enter the second guide channel 3405 due to the rotation of the reset lock 3420 and the elastic force of the reset spring 3430, and the protrusion 3421 will enter the non-limiting groove 3406 due to the guiding effect of the side walls of the second guide channel and the rotation of the reset lock 3420. At this time, the cleaning agent storage portion 340 will be lifted upward by a predetermined height.

[0127] After that, the user can take out the cleaning agent storage portion 340. During the taking-out process, the protrusion 3421 can slide along the third guide channel 3407 until the protrusion 3421 moves to the next gap, so that the cleaning agent storage portion 340 can be separated from the reset lock 3420. The third guide channel 3407 can include a seventh side wall 3407a and an eighth side wall 3407b, in which one end of the seventh side wall 3407a can be connected to the other end of the fifth side wall 3405b, and the other end of the seventh side wall 3407a can extend to the next gap. One end of the eighth side wall 3407b can be connected to the non-limiting groove 3406, and the other end can be connected to the first side wall of the next self-locking spring structure.

[0128] In the above embodiment, one structure of the self-locking and rebounding structure is described, and such structures can be arranged circumferentially around the outlet end 3401, so that the protruding portion 3421 can enter from one structure to another structure, so that the self-locking and rebounding operation can be repeated. In the present disclosure, four structures can be arranged circumferentially around the outlet end 3401, so that when the reset lock 3420 is rotated by 90°, it can be switched from one structure to another structure, thereby allowing the self-locking and rebounding operation to be performed again. However, the structure can also be other quantities, for example, it can be six structures, in the case of six structures, the reset lock 3420 is rotated by 60° each time to perform the next self-locking and rebounding operation. In addition, in the case of four structures, four protruding portions 3421 are correspondingly arranged on the reset lock 3420, and in the case of six structures, six protruding portions 3421 are correspondingly arranged on the reset lock 3420, and the number of the two can be correspondingly arranged. Among them, the structure can be arranged N, and the protruding portion can also be arranged N, or other quantities, and during the switching process between the locked state and the unlocked state, the reset lock 3420 can be rotated by an angle of 360° / N each time.

[0129] During the rotation of the reset lock 3420, due to the elastic force of the reset spring 3430, when the user presses and releases the cleaning agent storage portion 340, the reset lock 3420 is subjected to upward elastic force due to the elastic force of the reset spring 3430, and is pushed upward (for example, it can be acted on the reset lock 3420 by the ejecting piece 3440), so that after the protruding portion 3421 is separated from the locking groove, the protruding portion 3421 enters the third guide channel due to the action of the reset spring 3430, and with the rotation of the reset lock 3420, the protruding portion 3421 enters the non-limiting groove 3406.

[0130] In addition, an ejecting spring 3450 and a lifting piece 3460 can also be provided, wherein the ejecting spring 3450 cooperates with the lifting piece 3460 to eject at least a part of the cleaning agent storage portion 340 to the outside of the shell. Among them, the lifting piece 3460 can be in contact with the bottom surface of the cleaning agent storage portion 340, and can pass through the shell 3410.

[0131] According to one example of the present disclosure, the reset lock 3420 can be a ring structure, for example Figure 54As shown, the protrusion 3421 can be located on the inner annular surface of the reset lock 3420. Further, a locking structure 3422 can be provided on the reset lock 3420. The locking structure 3422 can correspond to the locking groove 3412 provided on the shell 3410. As an example, the locking groove 3412 corresponding to the locking structure 3422 can be provided on the bottom outer surface of the shell 3410. As shown in FIG. 34B, when the reset lock 3420 is rotated, the locking structure 3422 can be inserted into the locking groove 3412, so as to limit the rotation of the reset lock 3420. Figure 54 As shown, the protrusion 3421 can be located on the inner annular surface of the reset lock 3420. Further, a locking structure 3422 can be provided on the reset lock 3420. The locking structure 3422 can correspond to the locking groove 3412 provided on the shell 3410. As an example, the locking groove 3412 corresponding to the locking structure 3422 can be provided on the bottom outer surface of the shell 3410. As shown in FIG. 34B, when the reset lock 3420 is rotated, the locking structure 3422 can be inserted into the locking groove 3412, so as to limit the rotation of the reset lock 3420.

[0132] Although the above-described resilient locking structure is described in the present disclosure in connection with the base station, it should be understood by those skilled in the art that the resilient locking structure can also be used in other aspects and is not limited to the base station described in the present disclosure.

[0133] According to the technical solution of the present disclosure, the cleaning agent storage 340 is separately provided from the cleaning liquid storage 350 and the recovered liquid storage 360 and is disposed at the rear side of the adjacent position of the cleaning liquid storage 350 and the recovered liquid storage 360. The user can only press the cleaning agent storage 340 to lock and press again to unlock. In this way, there is no need to increase the release key and the like.

[0134] Generally, the cleaning agent storage 340 can be replaced to be inserted into the cleaning assembly 300, but there can be a leakage and the like in the cleaning agent storage 340.

[0135] In the present disclosure, a two-stage check valve can be provided inside the outlet end 3401 of the cleaning agent storage 340. The two-stage check valve can be provided upstream and downstream of the fluid. The first-stage check valve can be provided upstream of the fluid, and the second-stage check valve can be provided downstream of the fluid. In this way, the two-stage sealing structure can effectively prevent leakage.

[0136] In the present disclosure, a suitable check valve can be selected to prevent leakage. In the present disclosure, preferably, the first-stage check valve can be a duckbill valve, which can be made of soft material, such as soft rubber. The second-stage check valve can adopt a bead check valve. The bead check valve can include a sealing bead accommodated in a support body, and the support body can be accommodated inside the outlet end 3401.

[0137] Figure 55 FIG. 34A shows an exploded view of the cleaning agent storage 340, Figure 56A cross-sectional view of the cleaning agent storage 340 is shown. A first stage one-way valve 3471, for example in the form of a duckbill valve, can be arranged inside the outlet end 3401 and located at an upstream position, for example adjacent to the inlet of the outlet end 3401. A second stage one-way valve in the form of a sealing ball can be arranged at a downstream position, for example adjacent to the outlet of the outlet end 3401. The second stage one-way valve 3472 can comprise a sealing ball 3473 and a support body 3474. The sealing ball 3473 can be made of a material such as glass. The support body can be made of a flexible material. The sealing ball 3473 arranged inside the support body can move inside the support body 3474. In the present disclosure, the support body 3474 can be designed in the form of having a gap, for example Figure 55 As shown, the support body 3474 is capable of opening and closing to allow the sealing ball 3473 to move. In addition, a blocking structure can also be arranged inside the support body 3474. The sealing ball 3473 can achieve the function of one-way sealing when abutting against the blocking structure 3476. The blocking structure can be arranged at a lower position of the support body. The support body 3474 can be designed to limit the movement stroke of the sealing ball 3473. For example, a limiting structure 3477 can be arranged, wherein the limiting structure 3477 can be arranged such that when the sealing ball is lifted up, the sealing ball can move towards the upstream. When the sealing ball is not lifted up, the limiting structure 3477 can exert a pressure on the sealing ball 3473 towards the downstream, so that the sealing ball 3473 abuts against the blocking structure, thereby achieving the sealing effect.

[0138] When the cleaning agent storage 340 is installed to the cleaning assembly 300, the abutting interface or the lifting structure arranged at the abutting interface of the cleaning assembly 300 can lift up the sealing ball 3473, so that the sealing ball 3473 moves towards the upstream, and the sealing ball 3473 is separated from the blocking structure, thereby allowing the liquid to be discharged. In addition, a pump device such as a peristaltic pump can be arranged in the base station, so as to pump out the liquid from the cleaning agent storage 340. When the cleaning agent storage 340 is taken out, the sealing ball can also achieve the sealing function to prevent the residual liquid from flowing out.

[0139] Generally, there is a risk of leakage when the cleaning agent storage 340 is inverted or squeezed. The scheme of the present disclosure uses a two-stage sealing form. If the liquid leaks from the first stage sealing, the risk of leakage will be greatly reduced due to the presence of the second stage sealing. Moreover, after being placed in the base station, the sealing ball is lifted up, which does not affect the discharge of the liquid.

[0140] The cooperation between the surface cleaning device and the base station will be described in detail below.

[0141] During use of the surface cleaning device, the surface cleaning device can be determined to return to the base station based on the battery level of the surface cleaning device, the amount of dirt collected in the dirt collection portion, the level of cleaning of the mop pad, etc. For example, when the surface cleaning device is low on power, the surface cleaning device can also be controlled to return to the base station to charge. Additionally, when the surface cleaning device is low on cleaning fluid, the surface cleaning device can be controlled to return to the base station and initiate a fluid replenishment mode. Additionally, after the surface cleaning device returns to the base station, a self-cleaning mode can also be initiated to clean the mop pad of the surface cleaning device and to clean and collect dirt from the mop pad of the surface cleaning device. Once the surface cleaning device is docked with the base station, the drive wheels of the surface cleaning device can be stopped from rotating. Also, the charging contacts of both can be coupled to charge the battery of the surface cleaning device. Once docked, a self-cleaning mode, a fluid replenishment mode, and / or a self-emptying mode can be initiated.

[0142] The surface cleaning apparatus can be used for dry and / or wet cleaning of a surface. During dry cleaning, debris and other waste is collected by the cooperating action of the roll brush portion and the edge brush portion into a dust collection portion of the surface cleaning apparatus. The chamber of the dust collection portion defines a storage space for storing debris and other waste drawn into the surface cleaning apparatus, and the waste accumulates in the storage space due to gravity. When the dust collection portion is full of debris and other waste, the dust collection bin can be indicated as full, and airflow in the dust collection bin can be restricted from flowing freely. Optionally, one or more volume sensors can be provided in the dust collection portion or in the exhaust passage of the dust collection portion to detect the full condition of the dust collection portion. In some embodiments, the volume sensor can include a light emitter / detector arranged to detect when debris within the dust collection portion accumulates to a threshold level indicative of a full condition. When debris accumulates within the dust collection portion and reaches the full condition of the dust collection portion, the debris at least partially blocks the airflow, causing a drop in pressure and a reduction in the speed of the airflow within the dust collection portion. In other examples, the volume sensor can include a pressure sensor to monitor the pressure within the dust collection portion and detect the full condition of the collection bin when a threshold drop in pressure occurs. In some examples, the volume sensor can include a speed sensor to monitor the speed of the airflow within the dust collection portion and detect the full condition of the collection bin when the speed of the airflow falls below a threshold speed. In other examples, the volume sensor can include an ultrasonic sensor whose signal changes in accordance with the increasing density of the debris within the dust collection portion, such that a full signal is only emitted when the debris is compacted in the dust collection portion. This prevents the full condition from being triggered when lighter, fluffy debris extending from the top to the bottom of the dust collection portion, while there is actually a large volume available for collecting debris and other waste. When the dust collection portion is full (e.g., the full condition is detected), the surface cleaning apparatus can be returned to the base station to initiate a self-emptying mode. The debris evacuation suction port 15 can be opened to evacuate the debris into the dust exhaust assembly 200 (e.g., when the base assembly 100 is used in combination with the dust exhaust assembly 200). In some examples, when docked to the base station, the rear wall side position defined self-emptying suction interface 130 of the base assembly 100 interfaces with the suction port 15 of the surface cleaning apparatus, and the sealing structure provided at the ramp portion 116 can seal the corresponding position of the roll brush portion of the surface cleaning apparatus, thereby sealing the suction mouth of the roll brush portion. At this time, the airflow path inside the surface cleaning apparatus from the suction mouth to the dust collection portion is blocked, and the airflow path from the dust collection portion to the suction port 15 is opened to allow the debris and other waste to be evacuated. According to an optional embodiment of the present disclosure, an elastic baffle can be provided at the position of the base assembly 100 corresponding to the roll brush portion, so that when the surface cleaning apparatus is returned to the base assembly 100, the elastic baffle can be popped up to close the suction mouth of the roll brush portion, etc.

[0143] Before initiating the self-emptying mode, the surface cleaning device can send a confirmation signal to the base station that the surface cleaning device has successfully docked and is ready to begin self-emptying. For example, a radio frequency signal can be sent from the surface cleaning device to the base station and back to the surface cleaning device; or a pulse signal can be sent and received through the charging channel between the charging contacts. Alternatively, an infrared signal can be sent by the surface cleaning device to an infrared receiver of the base station. The self-emptying mode can be manually initiated by the user by pressing a button of the display control. The self-emptying mode can be locked by the processor / controller to prevent inadvertent activation of the self-emptying mode when the surface cleaning device is undocked or when docking is successful. Alternatively, the self-emptying mode can be automatic such that the self-emptying mode is controlled by the processor / controller and automatically initiated when the surface cleaning device is docked and successfully docked. For example, the self-emptying mode can be designed as a default setting to run after each cleaning operation of the surface cleaning device; or after a predetermined run time; or when the battery level of the surface cleaning device reaches a lower threshold. Further, the self-emptying mode can be initiated before the surface cleaning device is docked with the base station and the movement of the surface cleaning device into docking relationship with the base station can be considered as part of the self-emptying mode. In this case, the user can press an operable button or switch to initiate the self-emptying mode, the surface cleaning device is driven to the base station and docked with the base station.

[0144] Before initiating the self-cleaning mode, the surface cleaning device can send a confirmation signal to the base station that the surface cleaning device has successfully docked and is ready to begin self-cleaning. For example, a radio frequency signal can be sent from the surface cleaning device to the base station and back to the surface cleaning device; or a pulse signal can be sent and received through the charging channel between the charging contacts. Alternatively, an infrared signal can be sent by the surface cleaning device to an infrared receiver of the base station. The self-cleaning mode can be manually initiated by the user by pressing a button of the display control. The self-cleaning mode can be locked by the processor / controller to prevent inadvertent activation of the self-cleaning mode when the surface cleaning device is undocked or when docking is successful. Alternatively, the self-cleaning mode can be automatic such that the self-cleaning mode is controlled by the processor / controller and automatically initiated when the surface cleaning device is docked and successfully docked. For example, the self-cleaning mode can be designed as a default setting to run after each cleaning operation of the surface cleaning device; or after a predetermined run time; or when the battery level of the surface cleaning device reaches a lower threshold. Further, the self-cleaning mode can be initiated before the surface cleaning device is docked with the base station and the movement of the surface cleaning device into docking relationship with the base station can be considered as part of the self-cleaning mode. In this case, the user can press an operable button or switch to initiate the self-cleaning mode, the surface cleaning device is driven to the base station and docked with the base station.

[0145] Upon initiation of the liquid replenishment mode, the surface cleaning device can return to the base station and dock successfully, and the processor / controller can initiate the liquid replenishment mode. The flexible, retractable liquid replenishment interface can be docked with the liquid replenishment port of the surface cleaning device to enable the liquid replenishment mode. Prior to initiation of the liquid replenishment mode, the surface cleaning device can send an acknowledgement signal to the base station that the surface cleaning device has successfully docked and is ready to begin replenishing liquid. For example, a radio frequency signal can be sent from the surface cleaning device to the base station and back to the surface cleaning device; a pulsed signal can be sent and received through the charging channel between the charging contacts. Alternatively, an infrared signal can be sent by the surface cleaning device to an infrared receiver of the base station. The liquid replenishment mode can be manually initiated by the user by pressing a button or the like of the display control portion to initiate the mode. The liquid replenishment mode can be locked by the processor / controller to prevent inadvertent initiation of the liquid replenishment mode when the surface cleaning device is not parked or has not successfully docked. Alternatively, the liquid replenishment mode can be automatic such that the liquid replenishment mode is controlled by the processor / controller and automatically initiated upon parking of the surface cleaning device in the base station. For example, the liquid replenishment mode can be designed as a default setting to run after each cleaning operation of the surface cleaning device; or after a predetermined run time; or when the liquid level of the cleaning liquid of the surface cleaning device reaches a lower threshold or when the battery power of the surface cleaning device reaches a lower threshold. The liquid replenishment mode can be initiated prior to docking of the surface cleaning device with the base station, and the movement of the surface cleaning device into docking relationship with the base station can be considered as part of the liquid replenishment mode. In this case, the user can press a user operable button or switch to initiate the liquid replenishment mode, and the surface cleaning device is driven to the base station and docked for liquid replenishment.
