[0007] A reset latch, the reset latch including protrusions, wherein the number of protrusions is M, where M≥2; and

[0008] The elastic portion provides an elastic force to the reset latch.

[0009] When the insertion end is locked with the reset latch, the protrusion enters the guide channel along a notch in a locking structure and reaches the locking groove. The elastic force provided by the elastic part causes the protrusion of the reset latch to abut against the locking groove, thereby fixing the insertion end and the reset latch relative to each other. When the insertion end is released from the reset latch, pressure is applied to the insertion end, and the protrusion enters the exit channel, allowing the protrusion to exit along the exit channel through a notch in the next locking structure, thereby disengaging the protrusion from the locking groove.

[0010] According to at least one embodiment of the present disclosure, the reset latch is configured to be rotatable relative to the insertion end, and the rotation angle range of the reset latch is 360° / N in each process of the protrusion entering from one notch and exiting from another notch.

[0035] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0036] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0038] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0039] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0040] For descriptive purposes, this disclosure may use terms such as “below,” “under,” “below,” “under,” “above,” “above,” “higher,” and “side” (a pair of terms, such as “side of a component”, or “side of another component, such as “a component in another component”) to describe the spatial relationship, operation, etc. In addition to the terms or attachments, the drawing may depict different orientations from the description of the component. For example, in the illustration, if the device in the drawing is flipped, the component described as “below” or “under” other components or features will subsequently be positioned “above” said other components or features. Therefore, the exemplary term “below” can include both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 9.0 degrees or in other orientations), and thus, the use herein shall be interpreted accordingly.

[0041] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a (technical term, “include”)” and “and / or “(include)” are also intended to include complex variable forms. In addition, there are instances where integrals, steps, operations, parts, components and / or groups thereof are used in the features described herein, but this does not preclude the presence or addition of one or more other features, integrals, steps, operations, parts, components and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “approximately,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases of measured, calculated, and / or provided values ​​that will be recognized by those skilled in the art.

[0042] According to one embodiment of this disclosure, a base station is provided. This base station can be used to dock autonomous surface cleaning devices such as robotic vacuum cleaners.

[0043] Surface cleaning devices may include a generally circular or rectangular-circular housing. For example... Figure 1 As shown in Figure 2, the surface cleaning device 10 may include a wet cleaning section and a dry cleaning section. The wet cleaning section and the dry cleaning section may be disposed at the bottom of the housing and may contact the cleaning surface to perform wet cleaning and dry cleaning on the cleaning surface.

[0044] The wet cleaning section may include a first rotating member 11 and a second rotating member 12, and mopping components such as mops (not shown) may be respectively mounted on the first rotating member 11 and the second rotating member 12. The first rotating member 11 and the second rotating member 12 are arranged side by side and can rotate about a rotation axis respectively, so that the cleaning surface is mopped while the first rotating member 11 and the second rotating member 12 are in contact with the cleaning surface. A cleaning liquid reservoir may be provided inside the housing of the surface cleaning device, and cleaning liquid is supplied to the mopping components through a cleaning liquid supply port, thereby performing wet cleaning of the cleaning surface by the cleaning liquid absorbed by the mopping components.

[0045] The dry cleaning unit may include a roller brush 13 and side brushes 14. The number of side brushes 14 can be one or two. When one side brush is provided, it can be located on one side of the surface cleaning device; when two side brushes are provided, they can be located on opposite sides of the surface cleaning device. During the cleaning process, the side brushes 14 can rotate to collect debris and other waste near the roller brush 13. The rotating roller brush 13 then rolls the waste into a dust collection unit located inside the housing of the surface cleaning device. This dust collection unit can be in the form of a dust box, which collects and stores the waste from the cleaned surface.

[0046] Preferably, in this disclosure, the wet cleaning section is positioned behind the dry cleaning section relative to the operating direction of the surface cleaning device. This allows for a dry-then-wet cleaning process. Furthermore, the wet cleaning section can be moved vertically. When not performing wet cleaning, the wet cleaning section can be raised to avoid contact with the cleaning surface. During wet cleaning, the wet cleaning section can be controlled to contact the cleaning surface and can be provided with additional pressure, thus providing additional driving force or resistance to the surface cleaning device. In specific cleaning scenarios requiring the removal of stubborn stains, the provided pressure allows the mopping component of the wet cleaning section to make closer contact with the cleaning surface, resulting in better cleaning performance. Additionally, although the wet cleaning section in this disclosure is in the form of two rotating parts, it should be understood that it can also be configured as a single rotating part, for example, a tracked rotating part, which can be configured to rotate along or against the operating direction of the surface cleaning device to achieve wet cleaning of the surface.

[0047] Figure 3 A base station 20 according to one embodiment of the present disclosure is shown. This base station can dock with a surface cleaning device. When the surface cleaning device docks at the base station, dust, debris, and other waste collected in the dust collection section of the surface cleaning device are sucked into the base station, thereby emptying the dust collection section of the surface cleaning device, and / or charging the surface cleaning device, and / or cleaning the mopping components of the surface cleaning device, and / or replenishing the cleaning liquid container of the surface cleaning device with cleaning liquid.

[0048] like Figure 3 As shown, the base station 20 may include a base component 100, a first maintenance component 200, and a second maintenance component 300.

[0049] The base assembly 100 can provide a space for accommodating the surface cleaning device. When a part of the surface cleaning device enters the base assembly 100, the surface cleaning device can be charged through the charging interface 120 provided in the base assembly 100, and / or the dust, debris and other garbage collected in the dust collection section can be sucked to the first maintenance component 200 through the suction interface 130 provided in the base assembly 100, and / or the cleaning liquid can be replenished to the cleaning liquid container of the surface cleaning device through the liquid replenishment interface 140 provided in the base assembly 100; and / or the cleaning section provided in the base assembly 100 can be used to clean the mopping parts of the surface cleaning device.

[0050] The primary function of the first maintenance component 200 is to suck up dust, debris, and other waste collected in the dust collection section of the surface cleaning device and store the sucked-up waste. The second maintenance component 300 may include a cleaning liquid storage section and a recovery liquid storage section, and can be connected via pipes to provide the cleaning liquid stored in the cleaning liquid storage section to the liquid replenishment interface of the base component 100, thereby providing the cleaning liquid to the surface cleaning device. The recovery liquid, after self-cleaning the mopping components of the surface cleaning device, is sucked from the cleaning section of the base component 100 to the recovery liquid storage section via pipes.

[0051] In this disclosure, the first maintenance component 200 and the second maintenance component 300 can be used in conjunction with the base component 100 to form a base station with different maintenance modes. For example... Figure 4 As shown, the self-draining mode in different maintenance modes can be achieved by cooperating the first maintenance component 200 with the base component 100. When the first maintenance component 200 and the base component 100 are combined, the dust collection section of the surface cleaning device can be sucked up, thereby emptying the dust from the dust collection section of the surface cleaning device into the first maintenance component 200, thus realizing the self-draining function of the surface cleaning device. Figure 5 As shown, the second maintenance component 300 can be combined with the base component 100 to achieve a self-cleaning mode and / or a cleaning fluid replenishment mode in different maintenance modes. After combining the second maintenance component 300 with the base component 100, self-cleaning of the mopping component of the surface cleaning device and / or replenishment of cleaning fluid to the cleaning fluid reservoir of the surface cleaning device can be achieved. Additionally, as... Figure 3As shown, the first maintenance component 200, the second maintenance component 300, and the base component 100 can also be used together to achieve different maintenance modes, including self-draining mode, self-cleaning mode, and / or liquid replenishment mode. Specifically, the first maintenance component 200 can suck up the dust collection part of the surface cleaning device to empty the dust collection part, and the second maintenance component 300 can replenish cleaning liquid to the cleaning liquid container of the surface cleaning device and / or provide cleaning liquid to clean the mopping parts of the surface cleaning device. In addition, the base component 100 can also be used alone to charge the surface cleaning device. It should be noted that even when the base component 100 is combined with the first maintenance component 200 and / or the second maintenance component 300, the charging mode can also be selected simultaneously after selecting the corresponding mode of the first maintenance component 200 and / or the second maintenance component 300. Although the functions of the first maintenance component 200 and the second maintenance component 300 are explicitly defined in this disclosure, they are merely examples. Those skilled in the art should understand that maintenance components with other functions can also be selected to be used in conjunction with the base component, or a single-function maintenance component or a functionally integrated maintenance component can be used.

[0052] According to the modular base station disclosed herein, users can select different components as needed to match corresponding surface cleaning devices. For example, the first maintenance component 200 and / or the second maintenance component 300 are detachably attached to the base component 100. For example, for a surface cleaning device that only performs dry cleaning, the base component 100 can be selected to charge the surface cleaning device. If it is necessary to empty the dust collection part of the surface cleaning device, the first maintenance component 200 can be selected and cooperated with the base component 100 to empty the dust collection part of the surface cleaning device, thereby enabling a self-draining mode and / or a charging mode. For example, if it is not necessary to empty the dust collection part of the surface cleaning device, only the second maintenance component 300 and the base component 100 can be selected to perform only a self-cleaning mode, a liquid replenishment mode, and / or a charging mode. In addition, according to the modular base station disclosed herein, if a component is updated later, the user can easily replace the previous component with the updated component. Existing surface cleaning device base stations are typically single-function, while multi-functional base stations are bulky, incurring high user costs, and cannot be switched according to user needs. Therefore, the modular base station disclosed herein solves these problems and allows users to select specific functions based on hardware choices.

[0053] According to an optional embodiment of the combinable base station disclosed herein, the base assembly 100 can be designed to be located at the lower part, the first maintenance assembly 200 can be designed to be located at the middle part, and the second maintenance assembly 300 can be designed to be located at the upper part. However, the installation positions can also be changed according to actual conditions. In addition, the first maintenance assembly 200 and the second maintenance assembly 300 are respectively provided with combination parts that combine with the base assembly 100. Furthermore, other functional components can also be provided to realize other working modes according to actual needs.

[0054] In addition, although Figure 4 and Figure 5 The diagram shows the appearance of the first maintenance component 200 and the second maintenance component 300, indicating that they can be housed in different housings. However, in this disclosure, the first maintenance component 200 and the second maintenance component 300 can share a single housing. Both the first maintenance component 200 and the second maintenance component 300 are installed within this housing. Thus, when the user only needs the first maintenance component 200, it can be assembled solely within the housing; when only the second maintenance component 300 is needed, it can be assembled solely within the housing; and when both the first and second maintenance components are required, they can be assembled together within the housing. This allows for assembly before product delivery to the user, avoiding problems that may arise during assembly, and allows the user to select different functions according to their needs.

[0055] To allow the maintenance components to be reliably mounted on the base assembly 100, a mounting structure can be provided with the base assembly 100 and the functional components that interface with it. For example, if the first maintenance component 200 and the second maintenance component 300 each have separate housings, the mounting structure can be provided on either the first maintenance component 200 or the second maintenance component 300. When the first maintenance component 200 and the second maintenance component 300 share a component housing, the mounting structure can be provided on the component housing. As an example, the mounting structure may include an insert and a locking member, and the insert may be provided on the maintenance component while the locking member may be provided on the base assembly. Figure 7As shown, an insertion port 611 can be provided on the base assembly 100, which allows an insert provided by the maintenance component to be inserted. After the insert is inserted, it can be locked by a locking member 612. In another optional embodiment, the insert can be provided on the base assembly, and the insertion port can be provided on the maintenance component. Furthermore, the locking member can be provided on either the base assembly or the maintenance component. Furthermore, by locking the base assembly and the maintenance component, it is convenient for the user to move the base station. Moreover, when the first maintenance component 200 and the second maintenance component 300 share a component housing, the volume of the base can be effectively reduced.

[0056] <Base Components>

[0057] 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 (the rear housing shown in FIG. 6) and a 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.

[0058] 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; the figure shows the charging interface 120 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.

[0059] 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 1 The suction port 15 and suction nozzle 15 are aligned to connect with the dust collection section of the surface cleaning device. This allows the device to communicate with the dust collection section of the surface cleaning device when the first maintenance assembly 200 is in self-draining mode. The suction port 130 and suction nozzle 15 are aligned to draw debris from the integrated section of the surface cleaning device into the first maintenance assembly 200 via the suction port 131. A suction sealing section may be provided on the outer side of the suction port 130. This sealing section may surround the outer side of the suction port 130 and may be made of an elastic material. When the surface cleaning device is positioned in the base assembly 100, and the suction nozzle 15 abuts against the suction port 130 to form a pneumatic connection, a gas passage is sealed. Optionally, the suction port 130 may be located on the inner side of the base assembly 100, for example, on the inner side of the first housing 111, the second housing 112, or the third housing 113. Figure 6 and Figure 7 The suction port 130 is shown to be located on the inner side of the third housing 113.

[0060] Optionally, the base assembly 100 may include a fluid replenishment port 140, wherein the fluid replenishment port 140 may be disposed on the inner surface of the base assembly 100 and is made of a flexible material, allowing it to bend under pressure. This can be achieved, for example, by being disposed on the inner surface of the first housing 111, the second housing 112, or the third housing 113. Figure 6 and Figure 7The 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. After the base assembly 100 is docked, 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 second maintenance assembly 300 via a pipe to provide cleaning fluid from the second maintenance assembly 300 to the surface cleaning device for replenishment. Preferably, in this disclosure, the replenishment port 140 and the suction port 130 are disposed on opposite sides of the charging port 120.

[0061] 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.

[0062] 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.

[0063] 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 8As shown, the cleaning section may include a liquid channel 1155 and a drain port 1152. The liquid channel 1155 can receive liquid from the second maintenance component 300 through a pipeline and guide the liquid to the cleaning section to clean the mop-washing component of the surface cleaning device. The drain port 1152 can provide the recovered liquid after cleaning to the second maintenance component 300 through a pipeline to realize the function of recovering 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 components 1153. The number and position of the brushing components 1153 correspond to the number and position of the rotating components of the surface cleaning device. In this disclosure, there may be two brushing components 1153. When the rotating components rotate, the brushing components 1153 brush the mop-washing component to achieve the self-cleaning function of the mop-washing component. 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.

[0064] 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 7 The drying port 1154 is located on the lower housing shown, and has a predetermined height relative to the bottom surface of the fourth housing 114 to prevent liquid from entering. The drying port 1154 can occupy a certain area and can provide hot airflow from the bottom of the mop, thus achieving a better drying effect. The drying port 1154 can be in gas communication with the second maintenance assembly 300 through a pipe to receive airflow from the second maintenance assembly 300 (the airflow can be heated in the base assembly) and provide it to the mop, thereby realizing the drying function of the mop. In this disclosure, the drying port 1154 can be positioned at a certain height relative to the bottom of the cleaning space, and the number of drying ports can be one or more. The drying port is designed to extend in the radial direction of the mop to cover a larger area of ​​the mop. For example, the drying port can be provided as a strip that extends radially relative to the mop, or the number of drying ports can be set to multiple, with multiple drying ports distributed radially along the mop. The arrangement of multiple drying ports can be in the form of a fan-shaped arrangement.

[0065] Figure 9 and Figure 10 A front view and a perspective view of a base assembly 100 according to another embodiment are shown respectively. (Refer to...) Figure 9 and Figure 10The 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 9 The rear housing shown), the second housing 112 ( Figure 9 The left shell shown) and the third shell 113 ( Figure 9 (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 10 (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.

[0066] 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; the figure shows the charging interface 120 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.

[0067] 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 port 15 and the suction nozzle 15 are aligned to connect with the dust collection section of the surface cleaning device. This allows the device to communicate with the dust collection section of the surface cleaning device when the first maintenance assembly 200 is in self-draining mode. The suction port 130 and suction nozzle 15 are aligned to draw debris from the integrated section of the surface cleaning device into the first maintenance assembly 200 via the suction port 131. A suction sealing section may be provided on the outer side of the suction port 130. This sealing section may surround the outer side of the suction port 130 and may be made of an elastic material. When the surface cleaning device is positioned in the base assembly 100, and the suction nozzle 15 abuts against the suction port 130 to form a pneumatic engagement, a gas passage is sealed. Optionally, the suction port 130 may be located on the inner side of the base assembly 100, for example, on the inner side of the first housing 111, the second housing 112, or the third housing 113. Figure 9 and Figure 10 The suction port 130 is shown to be located on the inner side of the third housing 113.

[0068] Optionally, the base assembly 100 may include a liquid replenishment port 140, wherein the liquid replenishment port 140 may be disposed 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. Figure 9 and Figure 10 The suction port 130 is shown disposed on the inner side of the first housing 111. The replenishment port 140 extends outward 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 second maintenance assembly 300 via a pipe to supply cleaning fluid from the second maintenance 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.

[0069] 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.

[0070] 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.

[0071] 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 according to Figure 9 The cross-sectional view obtained from section AA is shown in Figure 11. As shown, the cleaning unit may include an outlet 1151 and a drain 1152. The outlet 1151 can be in fluid communication with the second maintenance component 300, and the cleaning liquid provided by the second maintenance component 300 can be sprayed out from the outlet 1151 to provide the cleaning liquid to the mopping component of the surface cleaning device. The drain 1152 can provide the recovered cleaning liquid to the second maintenance component 300 through a pipe to realize the recovery function of the recovered liquid. In addition, the cleaning unit may also include a brush 1153. The number and position of the brush 1153 correspond to the number and position of the rotating components of the surface cleaning device. In this disclosure, the number of brushes 1153 can be two, and when the rotating components are rotating, the brushes 1153 brush the mopping component installed on the rotating components to achieve the self-cleaning function of the mopping component. Furthermore, the cleaning unit may also include a drying port 1154 for drying the mopped parts. The drying port 1154 may be located at a position corresponding to the mopped parts and at a predetermined height from the bottom surface of the support 115. The drying port 1154 may be in gas communication with the second maintenance component 300 through a pipe, so as to receive drying gas from the second maintenance component 300 and supply it to the mopped parts, thereby realizing the drying function of the mopped parts.

[0072] Furthermore, according to some embodiments of this disclosure, a sealing structure 1161 may be provided on the ramp portion 116. The sealing structure 1161 may be recessed relative to the surface of the ramp portion 116, and its shape is configured to match the corresponding shape of the roller brush portion of the surface cleaning device. Thus, when the surface cleaning device is stopped at the base assembly 100, the sealing structure 1161 can airtightly seal the opening of the roller brush portion. After sealing, this effectively seals the suction nozzle at the roller brush portion that draws in debris. At this time, inside the surface cleaning device, the first airflow path from the suction nozzle near the roller brush portion to the dust collection portion is blocked, while the second airflow path from the dust collection portion of the surface cleaning device to the suction port 15 is opened. By closing the first airflow path, a greater suction force can be provided, thereby allowing for better emptying of debris and other waste from the dust collection portion. According to an optional embodiment of this disclosure, an elastic baffle may be provided at a position on the base assembly 100 corresponding to the roller brush section, so that when the surface cleaning device returns to the base assembly 100, the elastic baffle can spring up to close the suction nozzle of the roller brush section.

[0073] <First Maintenance Component>

[0074] Figure 12 An external schematic diagram of a first maintenance component according to an embodiment of the present disclosure is shown. The main function of the first maintenance component 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 first maintenance component 200 can be used in combination with the base component 100, and can also be used in conjunction with the second maintenance component 300. For example, the first maintenance component 200 can be detachably connected to the upper surface of the base component 100, and after connection, the first maintenance component 200 and the base component 100 can be formed integrally.

[0075] like Figure 12As shown, the first maintenance component 200 may include a first maintenance component housing 210 and an emptying collection section 220. The first maintenance component housing 210 has an opening on its side, and the emptying collection section 220 can be detachably installed into the first maintenance component housing 210 through this opening. The detachable direction of the emptying collection section 220 relative to the first maintenance component housing 210 is generally parallel to the ground direction where the base station is installed. After the first maintenance component 200 with the emptying collection section 220 is assembled into the base component 100, the emptying collection section 220 and the suction port 130 of the base component 100 are fluidly connected through a pipe. This allows debris in the dust collection section of the surface cleaning device to be sucked into the storage space of the emptying collection section 220, thereby emptying the dust collection section. Optionally, in this disclosure, the capacity of the emptying collection section 220 may be set to be at least three times the capacity of the dust collection section of the surface cleaning device. When it is necessary to detach the drain collection unit 220 from the first maintenance component housing 210, the user can press it, and the drain collection unit 220 will pop out due to the elastic force.

[0076] Figure 13 It shows that it will be as follows Figure 12 A schematic diagram of the first maintenance component 200 after its outer casing has been removed. Figure 13 As shown, the first maintenance component 200 may include a first suction source 230, which may be in the form of a fan and is disposed inside the housing 210 of the first maintenance component. In this disclosure, the first suction source 230 and the emptying collection section 220 may be disposed on the left and right sides of the housing 210 of the first maintenance component. The first suction source 230 generates a suction airflow, thereby creating a negative pressure state through the suction airflow, causing dust and other debris to enter the suction channel 221 of the emptying collection section 220 from the surface cleaning device through the suction interface and corresponding pipe. For example, the suction channel 221 may be connected to a pipe opening provided on the upper surface of the base component 100. Then, the dust and other debris enter the internal space defined by the housing of the emptying collection section 220 through the suction inlet.

[0077] Figure 14 A schematic diagram of the emptying collection section from another angle is shown. The emptying collection section 220 defines a receiving space for receiving and containing waste through its housing. The emptying collection section 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 emptying collection section 220. According to embodiments of this disclosure, such as... Figure 15As shown, the exhaust collection unit 220 may further include a first air outlet 227 and a second air outlet 228. In an optional embodiment of this disclosure, the suction inlet 226 is located on one side of the housing of the exhaust collection unit 220, while the first air outlet 227 and the second air outlet 228 may be located on the other side of the housing of the exhaust collection unit 220. This one side and the other side can be two opposite sides of the housing of the exhaust collection unit 220. Furthermore, the suction inlet 226 and the first air outlet 227 may be offset to the left relative to the centerline of the exhaust collection unit 220, and the second air outlet 228 may be offset to the right relative to the centerline of the exhaust collection unit 220.

[0078] like Figure 15 As shown, the emptying and collecting unit 220 may further include a switching unit 250. In Figure 13 The diagram shows the switching unit 250 installed in the housing of the drain collection unit 220. Figure 15 The diagram shows the case where the switching unit 250 and the exhaust collection unit 220 are separated. 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 air outlet 227 and close the second air outlet 228; in the second state, the switching unit 250 can close the first air outlet 227 and open the second air outlet 228. In this disclosure, the first air outlet 227 can be located close to the suction inlet 226. Optionally, the axis of the first air outlet 227 can coincide with the axis of the suction inlet 226, or the axis of the first air outlet 227 can be nearly coincident with the axis of the suction inlet 226, or the axis of the first air outlet 227 can be parallel to the axis of the suction inlet 226 and located in a plane perpendicular to the bottom side surface of the exhaust collection unit 220. For example, the first air outlet 227 can be located on the front side, close to the suction inlet 226. The second air outlet 228 can be located at a greater distance from the suction inlet 226 than the distance between the first air outlet 227 and the suction inlet 226. For instance, the second air outlet 228 and the suction inlet 226 can be arranged almost diagonally, with the central axis of the second air outlet and the central axis of the suction inlet being slightly smaller than the length of the receiving space.

[0079] In an optional embodiment of this disclosure, the accommodating space of the emptying and collecting section 220 may be provided with a cyclone separator or a dust bag. That is, the emptying and collecting section 220 may employ an interchangeable structure of a cyclone separator and a dust bag. Figure 16 A schematic diagram shows the internal space of the drain collection unit 220 with the end cap 270 removed. Figure 16The illustration shows a case where a cyclone separator is installed. An installation structure 241 can be provided on the inner wall of the empty collection section 220. The cyclone separator 240 and the dust bag can be installed into the receiving space of the empty collection section 220 through the installation structure 241. The inlets of the cyclone separator or the dust bag are connected to the suction inlet 226 to achieve fluid communication. Dust and other debris enter the cyclone separator or the dust bag through the suction inlet 226. As an example, the installation structure 241 can be provided on opposite sides of the suction inlet 226. When installing the cyclone separator, it can be engaged with the installation structures 241 on both sides. When installing the dust bag, the mounting plate for the dust bag can be inserted into the installation structure 241. In this disclosure, the first air outlet 227 serves as the air outlet when using the cyclone separator, and the second air outlet 228 serves as the air outlet when using the dust bag. When using a cyclone separator, the first outlet 227 is selected to choose an air duct close to the suction inlet 226. Dust and debris are thrown by the cyclone separator into the receiving space formed by the housing of the exhaust collection section 220, while air is discharged through the first outlet 227, which connects to the outlet of the cyclone separator. When using a dust bag, the second outlet 228 is selected to choose an air duct farther from the suction inlet 226. Dust and debris are retained in the dust bag located in the receiving space, while air is discharged through the second outlet 228. When using a cyclone separator, the cyclone separator occupies a portion of the receiving space, for example, one-third of the space, with the remaining space used for storing debris. When using a dust bag, by selecting the second outlet 228 to choose a farther air duct, the dust bag can be filled to the entire receiving space as airflow passes through it, thus making full use of the receiving space. Figure 15 As shown, the switching section 250 may be provided with a first opening 251 and a second opening 252. The switching section 250 can slide relative to the outer side of the emptying collection section 220, so that one of the first air outlet 227 and the second air outlet 228 is used as an air outlet depending on whether the cyclone separator or the dust bag is used. When the cyclone separator is used, the switching section 250 slides to a first state, in which the first opening 251 of the switching section 250 is located at the position of the first air outlet 227, so that the first air outlet 227 is used as an air outlet for the recovered airflow, while the second air outlet 228 is blocked by the switching section 250. When the dust bag is used, the switching section 250 slides to a second state, in which the second opening 252 of the switching section 250 is located at the position of the second air outlet 228, so that the second air outlet 228 is used as an air outlet for the recovered airflow, while the first air outlet 227 is blocked by the switching section 250.

[0080] Optionally, the emptying collection unit 220 may include a discharge unit 223, which can be closed to form a closed waste containing space, or opened to allow the user to empty the waste (waste collected by the cyclone separator) from the containing space. In an optional embodiment, the discharge unit 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 emptying collection unit 220 to be opened or closed. Additionally, a locking member 224 may be provided on the other side of the housing of the emptying collection unit 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 unit 223 for discharging dust and other waste. In an optional example of this disclosure, the discharge portion 223 may be provided on one side of the empty collection portion 220, and the end cap portion 270 may be provided on the other side of the empty collection portion 220, wherein the one side and the other side are opposite sides, and these two sides are adjacent sides of the side where the first air outlet 227, the second air outlet 228 and the suction inlet 226 are located.

[0081] Figure 17 A cross-sectional schematic diagram of the venting and collection unit 220 is shown. Figure 17 The diagram illustrates the automatic switching structure of the switching unit 250. This automatic switching structure may include a first spring 229. The first spring 229 may be disposed within the cavity formed by the housing of the exhaust collection unit 220. When a certain pressure is applied to the first spring 229, it is compressed, allowing the switching unit 250 to move towards the second air outlet 228 (to the left). When the pressure of the first spring 229 is released, the switching unit 250 can move towards the first air outlet 227 (to the right). In this way, when the cyclone separator 240 needs to be installed into the exhaust collection unit 220, the structure of the cyclone separator 240 causes the switching unit 250 to move to the left. After the cyclone separator 240 is installed, the switching unit 250 remains in a first state where the first opening 251 opens the first air outlet 227. When the cyclone separator 240 is removed, the tension of the first spring 229 causes the switching part 250 to move to the right. This allows the switching part 250 to move to a second state when the cyclone separator 240 is not installed. In this second state, the first opening 251 is closed, while the second air outlet 228 is open through the second opening 252. This method avoids the situation where, if the switching part 250 is switched manually, the user forgets to move it when replacing the cyclone separator and dust bag, resulting in an incorrect first or second state. Figure 17As shown, a first groove 2201 can be provided inside the housing of the drain collection section 220, and a corresponding engaging part 2401 is provided on the cyclone separator 240. After the cyclone separator 240 is installed onto the mounting structure 241, the engaging part 2401 can engage with the first groove 2201 to fix the cyclone separator 240 and prevent it from shifting. When it is necessary to remove the cyclone separator 240 from the drain collection section 220, the user can operate the engaging part 2401 to disengage it from the first groove 2201 and remove the cyclone separator 240.

[0082] According to one embodiment of this disclosure, the evacuation collection unit 220 can be removed or installed into the housing of the first maintenance component 200 by means of a press-fit mechanism. Reference will be made below. Figures 19 to 24 The self-locking structure of one embodiment will be described in detail below.

[0083] A first protrusion 2202 may be provided on the outer surface of the drain collection section 220, wherein the first protrusion 2202 is raised relative to other parts around the housing. For example, the first protrusion 2202 may be flush with the housing of the drain collection section 220.

[0084] The self-locking structure may further include a locking member 222. The locking member may include a body portion and an extension portion. The body portion may be disposed within and movable along the receiving member, while the extension portion extends from the body portion and is bendable toward the body portion under pressure. The locking member 222 may have a first recess 2221 corresponding to the first protrusion 2202, for example, provided on the extension portion. In the locked state, the first protrusion 2202 can be inserted into the first recess 2221 to lock the drain collection portion 220 into the housing of the first maintenance assembly 200. According to an alternative embodiment, such as... Figure 24 As shown, the locking member 222 may also be provided with a second recess 2222, so that the extension can be elastically deformed, or the first recess 2221 can be elastically deformed. The locking member 222 may be disposed in the receiving member 280 and slidable relative to the receiving member 280, and is restricted to only being able to... Figure 22 and Figure 23 (for Figure 22 The portion of the enlarged view shows the movement in the left-right direction. The housing 280 can be fastened to the housing of the first maintenance assembly 200.

[0085] The self-locking structure may include a reset spring 2801 and a reset rod 2802. One end of the reset spring 2801 may be fixedly connected to the receiving member 280, and the other end may be fixed to the locking member 222. One end of the reset rod 2802 may be disposed in the receiving member 280, and the other end (free end) may be disposed in the locking member 222. The reset rod 2802 may be a reset wire, such as a rigid hook rod. The locking member 222 may be provided with an entry groove 2223. The free end of the reset rod 2802 may slide in the entry groove 2223 and be guided by the wall of the entry groove 2223 to enter the locking groove 2225. When the reset rod 2802 is in the state of entering the locking groove 2225, the emptying collection part 220 is in a locked state. When unlocked from the locked state, the free end of the reset lever 2802 can enter the exit groove 2224, and guided by the wall of the exit groove, the free end of the reset lever 2802 can enter the communicating groove 2226. And when locking is required again, the free end of the reset lever 2802 can re-enter the entry groove 2223 until it is in the locking position 2225. Figure 23 The image shows that the free end of the reset lever 2802 is located in the locking slot 2225 and is in a locked state.

[0086] The locking and unlocking processes will be described in detail below. When locking, the user can press the end cap 270 after placing the drain collection unit 220 into the housing. The first protrusion 2202 of the drain collection unit 220, guided by the first guide surface 2227 of the locking member 222, enters the first recess 2221. Simultaneously, the free end of the reset rod 2802 can enter the entry groove 2223 along the connecting groove 2226, and guided by the wall of the entry groove 2223, the free end of the reset rod 2802 is positioned in the locking groove 2225, restricting the movement of the locking member. At this time, the reset spring 2801 is in a stretched state. During unlocking, the user can press the end cap 270 again. At this time, the free end of the reset rod 2802 will disengage from the locking groove 2225 and enter the exit groove 2224. Then, the free end of the reset rod 2802 enters the connecting groove 2226 along the exit groove 2224. At this time, due to the tension of the reset spring 2801 (the reset rod 2802 is not located in the locking slot 2225, and there is no constraint from the reset rod 2802), the locking member 222 moves together with the emptying collection part 220. During the movement, the first guide surface 2227 of the locking member 222 can contact the corresponding interference surface 2803 on the receiving member 280. Since the receiving member 280 has a downwardly extending slope, the interference surface 2803 can press the first guide surface 2227 downward, thereby allowing the first protrusion 2202 to disengage from the first recess 2221, and the emptying collection part 220 can pop out to the left. Afterwards, the user can pull out the emptying collection part 220.

[0087] Figure 26 An external schematic diagram of a first maintenance component according to another embodiment of the present disclosure is shown. The main function of the first maintenance component 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 first maintenance component 200 can be used in combination with the base component 100, and can also be used in conjunction with the second maintenance component 300. For example, the first maintenance component 200 can be detachably connected to the upper surface of the base component 100, and after connection, the first maintenance component 200 can be integrally formed with the base component 100.

[0088] like Figure 26 As shown, the first maintenance component 200 may include a first maintenance component housing 210 and an emptying collection section 220. The first maintenance component housing 210 has an opening on its side, and the emptying collection section 220 can be plugged into the first maintenance component housing 210 through this opening. The pluggable direction of the emptying collection section 220 relative to the first maintenance component housing 210 is generally parallel to the ground direction where the base station is installed. After the first maintenance component 200 with the emptying collection section 220 is assembled to the base component 100, the emptying collection section 220 and the suction port 130 of the base component 100 are fluidly connected through a pipe. This allows debris in the dust collection section of the surface cleaning device to be sucked into the storage space of the emptying collection section 220, thereby emptying the dust collection section. Optionally, in this disclosure, the accommodating volume of the emptying collection section 220 may be set to be at least three times the accommodating volume of the dust collection section of the surface cleaning device.

[0089] Figure 27 It shows that it will be as follows Figure 26 This is a schematic diagram showing the side and bottom housings of the first maintenance component 200 after removal. Figure 27 As shown, the first maintenance component 200 may further include a first suction source 230, which may be in the form of a fan and is disposed inside the housing 210 of the first maintenance component. In this disclosure, the first suction source 230 and the emptying collection section 220 may be disposed on the left and right sides of the housing 210 of the first maintenance component. The first suction source 230 generates a suction airflow, thereby causing dust and other debris to enter the suction channel 221 of the emptying collection section 220 from the surface cleaning device through the suction port 130 and the corresponding pipe. For example, the suction channel 221 may be connected to the pipe opening provided on the upper surface of the base component 100. Then, the dust and other debris enter the internal space defined by the housing of the emptying collection section 220 through the suction inlet.

[0090] Figure 28 and Figure 29Schematic diagrams of the emptying collection section from different angles are shown. The emptying collection section 220 defines a receiving space for receiving and accommodating waste through its housing. The emptying collection section 220 may include a handle 260, which is disposed on one side of the emptying collection section 220. The user can use the handle 260 to insert the emptying collection section 220 into or remove it from the first maintenance component housing 210.

[0091] Figures 30 to 32A schematic diagram of a handle portion 260 according to an embodiment of the present disclosure is shown. As shown, according to an optional embodiment, the handle portion 260 may include a first portion 261, a second portion 262, and a third portion 263. The second portion 262 and the third portion 263 may be fitted together, and the first portion 261 may be located between the second portion 262 and the third portion 263. The first portion 261 may include a first component and a second component, and the two independent portions may respectively include a first inclined surface 2611 and a second inclined surface 2612. When the drain collection unit 220 is inserted into the first maintenance component housing 210, the first inclined surface 2611 and the second inclined surface 2612 can abut against the housing of the first maintenance component housing 210. Due to the pushing force applied by the user, the first inclined surface 2611 and the second inclined surface 2612 will retract, allowing the drain collection unit 220 to be fully inserted into the first maintenance component housing 210. After full insertion, the first inclined surface 2611 and the second inclined surface 2612 will spring back and extend into the corresponding mounting holes of the first maintenance component housing 210, thereby securing the first maintenance component housing 210. The first component of the first part 261 may be provided with a third inclined surface 2613, and the second component of the first part 261 may be provided with a fourth inclined surface 2614. Correspondingly, the second part 262 may be provided with a fifth inclined surface 2621 and a sixth inclined surface 2622. The third inclined surface 2613 and the fifth inclined surface 2621 cooperate with each other, and the fourth inclined surface 2614 and the sixth inclined surface 2622 cooperate with each other. When the user squeezes the second part 262, the fifth inclined surface 2621 of the second part 262 can slide into the third inclined surface 2613. The cooperation between the third inclined surface 2613 and the fifth inclined surface 2621 causes the first inclined surface 2611 to disengage from the corresponding mounting hole of the first maintenance component housing 210. The sixth inclined surface 2622 of the second part 262 can slide into the fourth inclined surface 2614. The cooperation between the fourth inclined surface 2614 and the sixth inclined surface 2622 causes the second inclined surface 2612 to disengage from the corresponding mounting hole of the first maintenance component housing 210. This allows the user to remove the emptying collection section 220 from the first maintenance component 200. The third part 263 can be used to support the first part 261, for example, by guiding the movement of the first part 261. Furthermore, an elastic component can be provided between the second part 262 and the third part 263 so that the second part 262 returns to its original position relative to the third part 263 after the user squeezes it.

[0092] Optionally, the emptying collection section 220 may include a discharge section 223, which can be closed to form a closed waste containing space, or opened to allow the user to empty the waste from the containing space. In an 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 emptying collection section 220 to be opened or closed. Additionally, a locking member 224 may be provided on the other side of the housing of the emptying collection section 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 emptying collection section 220, while the handle 260 may be located on the other side of the emptying collection section 220, wherein the one side and the other side are opposite sides.

[0093] Optionally, the emptying collection section 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 empty collection section 220 may be provided with a cyclone separator or a dust bag. That is, the empty collection section 220 employs an interchangeable structure of a cyclone separator and a dust bag. Figure 33 A schematic diagram showing a cyclone separator 240 is provided. The cyclone separator 240 can be mounted into the receiving space of the exhaust collection section 220 via a mounting structure 241. The mounting structure 241 can be provided 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 both the cyclone separator and 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.

[0094] 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.

[0095] In this disclosure, preferably, the discharge part 223 can be provided on the first side (left side) of the empty collection part 220, the handle part 260 can be provided on the second side (right side) of the empty collection part 220, the maintenance cover part 225 can be provided on the third side (upper side) of the empty collection part 220, the inlet of the suction channel 221 can be provided on the fourth side (lower side) of the empty collection part 220 and can be provided at a position adjacent to the fifth side (rear side) of the empty collection part 220, and the switching part 250 can be provided on the sixth side (front side) of the empty collection part 220.

[0096] The switching unit 250 can be a structure for switching air ducts. Figure 35 The diagram shows a schematic of the removal of the switching unit. Figure 36 A schematic diagram showing the switching unit set in the first state is shown. Figure 37 A schematic diagram showing the switching unit in the second state is shown.

[0097] like Figure 35 As shown, a first air outlet 227 and a second air outlet 228 are provided on the side shell of the emptying and collecting section 220. Optionally in this disclosure, the suction inlet 226 can be located adjacent to the rear side of the emptying and collecting section 220, and the first air outlet 227 and the second air outlet 228 can be located on the front side of the emptying and collecting section 220. For example Figure 37 As shown, the first air outlet 227 can be located close to the suction inlet 226, and the second air outlet 228 can be located far from the suction inlet 226. The first air outlet 227 and the second air outlet 228 can be spaced apart by a predetermined distance. Preferably, in this disclosure, the axis of the first air outlet 227 can coincide with the axis of the suction inlet 226; for example, the first air outlet 227 can be located on the front side at the position closest to the suction inlet 226.

[0098] In this disclosure, the first air outlet 227 serves as the air outlet when using a cyclone separator, and the second air outlet 228 serves as the air outlet when using a dust bag. When using a cyclone separator, the first air outlet 227 is selected to choose an air duct close to the suction inlet 226. Dust and debris are thrown into the receiving space by the cyclone separator, while air is discharged through the first air outlet 227, which connects to the outlet of the cyclone separator. When using a dust bag, the second air outlet 228 is selected to choose an air duct farther from the suction inlet 226. Dust and debris are retained in the dust bag located in the receiving space, while air is discharged through the second air outlet 228. When using a cyclone separator, the cyclone separator occupies a portion of the receiving space, for example, one-third of the space, with the remaining space used for storing debris. When using a dust bag, by selecting the second air outlet 228 to choose a farther air duct, the dust bag can be fully filled into the receiving space as airflow passes through it, thus making full use of the receiving space.

[0099] Figure 38 A schematic diagram of a switching section 250 according to an embodiment of the present disclosure is shown. The switching section 250 may be provided with a first opening 251 and a second opening 252. The switching section 250 can slide relative to the front side of the emptying collection section 220. For example, when the emptying collection section 220 is removed, the user can manually toggle the switching section 250 so that one of the first air outlet 227 and the second air outlet 228 becomes the air outlet, depending on the use of the cyclone separator or dust bag. When using a cyclone separator, the switching section 250 slides to... Figure 35 In the first state shown, the first opening 251 of the switching unit 250 is located at the position of the first air outlet 227, thereby making the first air outlet 227 an air exhaust outlet for the reclaimed airflow, while the second air outlet 228 is blocked by the switching unit 250. When using a dust bag, the switching unit 250 slides to... Figure 36 In the second state shown, the second opening 252 of the switching unit 250 is located at the position of the second air outlet 228, so that the second air outlet 228 serves as an air outlet for the reclaimed airflow, while the first air outlet 227 is blocked by the switching unit 250.

[0100] Optionally, a blocking part 2281 may be provided at or near the second air outlet 228, wherein the blocking part 2281 has a preset tilt angle, wherein the tilt angle is set to extend away from the first air outlet 227. The blocking part 2281 can prevent the dust bag from protruding outward from the second air outlet 228 and block the airflow discharged from the second air outlet 228.

[0101] Therefore, according to the above design of this disclosure, when using the cyclone separator, the first outlet 227 has a short duct distance, allowing dust and debris to be thrown into the left-side receiving space, and facilitating the dumping of debris from the left side. When using the dust bag, the second outlet 228 allows airflow from the suction inlet 226 to the second outlet 228, with a long duct distance, enabling the dust bag to fully expand within the receiving space, thus making full use of the receiving space.

[0102] <Second Maintenance Component>

[0103] like Figure 5 As shown, the second maintenance component 300 may include a side housing 310 and an upper housing 320. The side housing 310 forms a storage space for the second maintenance component 300. The upper housing 320 can be opened or closed. A display control unit 330, such as a touchscreen, may be provided on the upper housing 320. Although shown in the figures as being located on the upper housing 320, those skilled in the art will understand that it may also be located on the side housing 310, for example, on the front side housing. The display control unit 330 can display the operating status of the base station and / or the surface cleaning device, and can also receive user input instructions to implement corresponding control. For example, the display control unit 330 can communicate with the processor components of the base station and / or the processor components of the surface cleaning device. In an alternative embodiment, the display control unit may be permanently installed on the base station and may include one or more of the following indication and / or control functions: power switch; indication that the base station is full of debris or other waste; full / empty indication of the base station's cleaning liquid storage unit, cleaning agent storage unit, and / or recycling liquid storage unit; cleaning status indication of the surface cleaning device; control for dispatching the surface cleaning device back to the base station for maintenance; control for pausing / resumpting maintenance, etc.

[0104] Additionally, an opening may be provided in the upper housing 320 to allow the cleaning agent storage unit 340 to be inserted into the storage space of the second maintenance component 300. The user can press the cleaning agent storage unit 340 to push at least a portion of it into the storage space, and the user can press the cleaning agent storage unit 340 again and elastically eject at least a portion of it from the storage space.

[0105] Figure 40A schematic diagram of the second maintenance assembly 300 after the upper housing 320 has been removed is shown. The storage space of the second maintenance assembly 300 can accommodate a cleaning liquid storage unit 350 and a recovery liquid storage unit 360. The cleaning liquid storage unit 350 can be used to store cleaning liquids such as cleaning water, and the cleaning liquid can be mixed with cleaning agents such as detergents stored in the cleaning agent storage unit 340. The mixed liquid can be supplied to the base assembly 100, and then provided to a surface cleaning device and / or a mop for cleaning the surface cleaning device.

[0106] Figure 41 A schematic diagram of a cleaning liquid storage unit according to one embodiment of the present disclosure is shown. The cleaning liquid storage unit 350 can be cylindrical, bucket-shaped, or other suitable shapes, and may include a first side wall, a first bottom wall, and a first cover. The first cover 351 is provided with a first handle 352, which allows the cleaning liquid storage unit 350 to be removed from the second maintenance assembly 300 after the upper housing 320 of the second maintenance assembly 300 is opened, and cleaning liquid can be replenished to the cleaning liquid storage unit 350 by opening the first cover 351. In an optional embodiment of the present disclosure, the first cover 351 can be locked in a closed state by a first locking part 353, such as a snap-lock, and the first cover 351 can be opened by unlocking the first locking part 535.

[0107] Figure 42 A schematic diagram of the cleaning liquid storage section after the first cover has been removed is shown. Figure 42As shown, the first sidewall 354 and the first bottom wall 355 form a space for storing a cleaning liquid, such as cleaning water. A first float 356 may be provided inside the cleaning liquid storage section 350, and the first float 356 is located near the first bottom wall 355. The first float 356 may be provided with a magnet or be formed of a magnetic material. When there is no cleaning liquid in the cleaning liquid storage section 350, the first float 356 may fall, for example, by contacting the first bottom wall 355. When there is cleaning liquid in the cleaning liquid storage section 350, the first float 356 may rise due to the buoyancy of the liquid. The stroke of the first float 356 may be set to a predetermined distance, for example, a predetermined height from the first bottom wall 355. Furthermore, to limit the stroke of the first float 356, a first stroke limiting part 357 may be provided around the first float 356. Furthermore, to detect the position of the first float 356, a magnetic field detection unit, such as a Hall sensor, can be installed at a corresponding position on the outside of the cleaning liquid storage unit 350. Additionally, the display control unit 330 can prompt the user based on the detection information from the magnetic field detection unit. In this disclosure, the function of the first float 356 can be simply configured to detect the presence of cleaning liquid in the cleaning liquid storage unit 350; therefore, the stroke of the first float 356 can be set to allow it to move a short distance relative to the first bottom wall 355. Additionally, a first filter unit 358 can be installed inside the cleaning liquid storage unit 350, positioned near the first bottom wall 355. The first filter unit 358 filters the cleaning liquid supplied from the cleaning liquid storage unit 350.

[0108] Figure 43 A schematic diagram of a reclaimed liquid storage unit according to one embodiment of the present disclosure is shown. The reclaimed liquid storage unit 360 can be cylindrical, bucket-shaped, or other suitable shapes, and may include a second side wall, a second bottom wall, and a second cover. The second cover 361 is provided with a second handle 362, which allows the reclaimed liquid storage unit 360 to be removed from the second maintenance assembly 300 after the upper housing 320 of the second maintenance assembly 300 is opened, and the reclaimed liquid in the reclaimed liquid storage unit 360 to be poured out by opening the second cover 361. In an optional embodiment of the present disclosure, the second cover 361 can be locked in a closed state by a second locking part 363, such as a snap-lock, and the second cover 361 can be opened by unlocking the second locking part 536.

[0109] Figure 44 A schematic diagram of the recycled liquid storage section after the second cover is removed is shown. Figure 44As shown, the second side wall 364 and the second bottom wall 365 form a space for storing the recovered liquid. A second float portion 366 may be provided inside the recovered liquid storage portion 360, and the second float portion 366 is provided at a position adjacent to the second cover portion 361. The second float portion 366 may be provided with a magnet or formed of a magnetic material. When the recovered liquid in the recovered liquid storage portion 360 reaches the liquid level threshold, the second float portion 366 can rise by the buoyancy of the recovered liquid. In addition, a blocking portion 367 may be included, and the blocking portion 367 is connected to the second float portion 366 so that the two are linked. Specifically, when the position of the second float portion 366 rises, the position of the blocking portion 367 drops. In this way, 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, thereby preventing the recovered liquid from continuing to enter the recovered liquid storage portion 360 to avoid overflow of the recovered liquid from the recovered liquid storage portion 360. When the position of the second float portion 366 drops, the position of the blocking portion 367 rises, 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 connection portion between it 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 may 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 may be only set to detect whether the recovered liquid in the recovered liquid storage portion 360 reaches the liquid level threshold, and when it reaches the liquid level threshold, the user can be prompted through the display of the display control portion 330. A liquid inlet 369 is provided in the recovered liquid storage portion 360, and the recovered liquid can enter the inside of the recovered liquid storage portion 360 through the liquid inlet 369. Specifically, a vacuum pump may be provided downstream of the exhaust port 368, and the inside of the recovered liquid storage portion 360 is made to form a vacuum state by 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 this 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.

[0110] According to an optional embodiment of the present disclosure, a sterilization and disinfection device may be provided relative to the recovered liquid storage portion 360. Figure 45 The schematic diagram of the sterilization and disinfection device provided in the recovered liquid storage portion 360 is shown. The sterilization and disinfection device may include a light source, and in Figure 28The light source is shown in the form of a lamp tube 381, which can be located near the bottom of the recycled liquid storage section 360 or near the side wall of the recycled liquid storage section 360. There can be one or more lamp tubes 381, which emit disinfecting and sterilizing light, such as ultraviolet light, to disinfect the liquid contained in the recycled liquid storage section 360. The light guide 382 can be provided correspondingly to the lamp tube 381. The light guide 382 can be provided at the inner bottom end of the recycled liquid storage section 360 or on the inner wall of the recycled liquid storage section 360. When the lamp tube 381 is provided near the bottom end of the recycled liquid storage section 360, the light guide 382 can be provided on the inner bottom surface of the recycled liquid storage section 360 and extend along the longitudinal direction of the recycled liquid storage section 360, guiding the light to be evenly distributed within the recycled liquid storage section 360. When the lamp tube 381 is provided near the outer side of the recycled liquid storage section 360, the light guide 382 can be provided on the inner side wall of the recycled liquid storage section 360 and extend along the transverse direction of the recycled liquid storage section 360, guiding the light to be evenly distributed within the recycled liquid storage section 360, thereby improving the coverage of sterilization and disinfection. The number of light guides 382 can be one or more. When there is only one light guide 382, ​​it is installed at the center of the bottom or side wall of the recycled liquid storage section 360. When there are two or more light guides 382, ​​they are installed evenly or symmetrically at the center of the bottom or side wall of the recycled liquid storage section 360. Symmetrical or uniform installation helps the light guides 382 to guide the light evenly, thereby effectively improving the coverage of sterilization and disinfection.

[0111] The light guide 382 can be one or more of the following: a cylinder, a prism (triangular prism, square prism, etc.), or a square prism. The light guide 382 is integrally formed with the recycled liquid storage unit 360, or the light guide 382 can be detachably mounted to the recycled liquid storage unit 360. When the light guide 382 can be detachably mounted to the recycled liquid storage unit 360, the recycled liquid storage unit 360 is provided with a mounting structure for mounting the light guide 382. The recycled liquid storage section 360 has a mounting post, and the light guide section 382 has a mounting cavity at its port. The mounting cavity is located at one end of the light guide section 382, ​​or the light guide section 382 can be a hollow structure with the hollow structure at one end serving as the mounting cavity. The mounting cavity can be placed on the mounting post. The mounting post and mounting cavity work together to mount the light guide section 382 onto the recycled liquid storage section 360. The end of the light guide section 382 connected to the recycled liquid storage section 360 is sealed. The unconnected end of the light guide section 382 also needs to be sealed to prevent wastewater from entering and making cleaning difficult. A connector is provided inside the recycled liquid storage section 360, connecting the light guide section 382 to the side wall of the recycled liquid storage section 360 and fixing the light guide section 382. The connector can be a connecting rod or a connecting arm, and the connector is made of a rigid or flexible thin material that is not easily contaminated and does not block ultraviolet rays. The light guide has a high light transmittance material structure and can be used with light guide structures such as ABS, AS (S return AN), liquid PC storage, PM storage part M3A6, and the bottom light guide structure can be a high transmittance material material.

[0112] In the above embodiment, the light source is described as a lamp tube, but it can also be in the form of an LED chip or the like. For example, when it is an LED chip, the chip is mounted on a mounting plate near the bottom of the recycled liquid storage section 360. The lower surface of the recycled liquid storage section 360 has a recess that extends inwards, protruding inwards relative to the lower inner surface to form a protrusion relative to the lower inner surface. A light guide section 382 has a mounting cavity that nests into the protrusion, mounting the light guide section 382 onto the recycled liquid storage section 360. The number of LED chips is one or more, and the LED chips emit disinfecting and sterilizing light, such as ultraviolet light, to disinfect the liquid contained in the recycled liquid storage section 360. The technical solution disclosed herein involves setting a light-guiding structure within the 360° storage section of the base station's recycled liquid to guide the propagation direction of ultraviolet rays, thereby effectively increasing the intensity and radiation area of ​​ultraviolet radiation. This solves the problems of low coverage and poor effectiveness of sterilization and disinfection within the water tank, as well as the odor problem of the tank, without increasing additional costs, given a fixed product space.

[0113] Figure 46 and Figure 47 Schematic diagrams showing the internal structure after the housing of the second maintenance component has been removed are shown below. (Refer to the diagrams below.) Figure 46 and Figure 47 To explain in detail the liquid distribution system of the base station.

[0114] The liquid distribution system may include a first liquid distribution structure, which may include a first conduit 411 and a first pumping unit 412. The first pumping unit 412 delivers the cleaning liquid contained in the cleaning liquid storage unit 350 to the mixing unit 370. In this disclosure, the first pumping unit 412 is preferably an electromagnetic pump. The liquid distribution system may also include a second liquid distribution structure, which may include a second conduit 421, which provides cleaning agent from the cleaning agent storage unit 340 to the mixing unit 370. Additionally, the liquid distribution system may include a second pumping unit 422, which in this disclosure is preferably in the form of a peristaltic pump. In this disclosure, the mixing unit 370 can mix the cleaning liquid from the cleaning liquid storage unit 350 and the cleaning agent from the cleaning agent storage unit 340, and provide the mixed liquid to the base assembly 100. This allows the mixed liquid to be used to clean the mopping component of the surface cleaning device and / or to provide the mixed liquid to the surface cleaning device for cleaning the surface. Furthermore, as an optional embodiment, cleaning liquid from the cleaning liquid storage section 350 can be directly supplied to the base assembly 100 via the first liquid dispensing structure for supplying to the surface cleaning device. As an example, the cleaning liquid from the cleaning liquid storage section 350 and the cleaning agent from the cleaning agent storage section 340 can be supplied to the mixing section 370 via their respective pipes. Preferably, in this disclosure, the cleaning liquid and cleaning agent can be received separately via pipes and supplied together to the mixing section 370, for example via a three-way valve (e.g., a three-way valve). Figure 46(As shown in area A) The cleaning agent and cleaning liquid are received and supplied together to the mixing unit 370 through an inlet pipe. Additionally, a third liquid distribution structure can supply the mixed liquid from the mixing unit 370 to the base assembly 100. This third liquid distribution structure may include a third pipe 431, a third pumping unit 432, a mixing supply port 433, and a supply pipe 434. The third pipe 431 can communicate with the outlet interface 376 of the mixing unit 370. The mixed liquid is supplied to the mixing supply port 433 via the supply pipe 434 through the pumping action of the third pumping unit 432, and the mixed liquid is supplied to the base assembly 100 by docking the mixing supply port 433 with a corresponding part of the base assembly 100. The third pumping unit 432 is preferably a diaphragm pump. Furthermore, a cleaning agent storage unit detection device 451 may be provided, which can be used to detect whether the cleaning agent storage unit is in the appropriate position, i.e., to detect whether cleaning agent can be supplied. The cleaning agent storage section detection device 451 can be installed below the cleaning agent storage section and can be in the form of a photoelectric sensor.

[0115] The fourth liquid distribution structure may include a fourth conduit 441, which is connected to the base assembly 100 via a fourth inlet 442 to extract the recovered liquid from the base assembly 100 after cleaning the mop. Furthermore, the fourth liquid distribution structure may also include a fourth pumping device, such as a vacuum pump 443. An exhaust conduit 444 may be connected to the vacuum pump 443. Operation of the vacuum pump 443 creates a vacuum in the recovered liquid storage unit 360, allowing the recovered liquid to be drawn into the recovered liquid storage unit 360 via the fourth conduit 441, and the extracted gas to be discharged via the exhaust conduit 444, while the recovered liquid remains in the recovered liquid storage unit 360.

[0116] Figures 48 to 50 A schematic diagram of a mixing unit 370 according to one embodiment of the present disclosure is shown. As shown, the mixing unit 370 may include a first impeller portion 371, a second impeller portion 372, and a drive shaft 373. The first impeller portion 371, the second impeller portion 372, and the drive shaft 373 are housed within a housing of the mixing unit 370. Figure 47As shown, the mixing unit 370 can receive detergent and cleaning liquid from a three-way valve via a conduit. The mixed liquid in the mixing unit 370 can be supplied to the base assembly 100 and / or the surface cleaning device via a third conduit 431. For example, an inlet port 375 and an outlet port 376 can be provided on the housing of the mixing unit 370, wherein the inlet port 375 can receive detergent and cleaning liquid, and the outlet port 376 can supply the mixed liquid to the third conduit. However, those skilled in the art will understand that the three-way valve form described above is not required; instead, the mixing unit 370 can be provided with separate inlets for receiving detergent and cleaning liquid respectively.

[0117] In this disclosure, the inlet interface 375 can be correspondingly configured with the first impeller portion 371. As shown in FIG49 (showing the internal structure), the first impeller portion 371 may include a plurality of first blades, wherein the blade surface of the first blades can be configured as an arc surface to withstand the impact force and / or gravity of the liquid entering through the inlet interface 375, so that the first impeller portion 371 can be rotated by the liquid from the inlet interface 375. The first impeller portion 371 can be fixedly sleeved on the drive shaft 373, and the second impeller portion 372 is also fixedly sleeved on the drive shaft 373. When the first impeller portion 371 rotates, it will drive the drive shaft 373 to rotate, thereby causing the second impeller portion 372 to rotate as well. In this disclosure, the first impeller portion 371 can be regarded as the rotation driving part, while the second impeller portion 372 can be regarded as the rotation driven part. The rotation of the second impeller 372 mixes cleaning liquids, such as cleaning water, and detergents, such as washing agents, which enter the mixing section 370; therefore, the second impeller 372 acts as a stirring device. After thorough mixing, the mixed liquid can be supplied externally through a third pipe 431 located near the bottom of the mixing section 370.

[0118] The drive shaft 373 is supported on the top surface of the mixing section 370 by a first bearing 3731 and on the bottom surface of the mixing section 370 by a second bearing 3732, which effectively reduces rotational resistance and avoids noise. The first impeller section 371 and the second impeller section 372 can be fixed to the drive shaft 373 by axial fastening devices and radial fastening devices, respectively. As an example, the first impeller section 371 can be fixed to the drive shaft 373 by a first axial retaining spring 3733 and a first radial retaining groove 3734, and the second impeller section 372 can be fixed to the drive shaft 373 by a second axial retaining spring 3735 and a second radial retaining groove 3736. This fixing method effectively prevents radial and axial runout of the first impeller section 371 and the second impeller section 372 during operation. Of course, those skilled in the art should understand that other fixing methods can also be used. According to the internal arrangement of the mixing section of this disclosure, many advantages such as compactness, low noise, and low cost can be achieved.

[0119] In this disclosure, the direction of the fluid F entering the mixing section 370 from the inlet interface 375 can be radial to the blades, for example, see Figure 50 and Figure 51 Optionally, the point at which the fluid impact force is applied to each blade of the first impeller portion 371 can be located at the center of the blade. This allows the first impeller portion 371 to rotate effectively through fluid impact, and the direction of the fluid impact can be approximately radial to the blade. Each blade of the first impeller portion 371 is arc-shaped, and the axial angle of the arc-shaped blade can range from 5° to 85°. For example, from the lower portion to the upper portion of the arc-shaped blade (here, "up and down" refers to the position of the arc-shaped blade when it is in operation), the angle of the arc-shaped blade gradually decreases relative to the axial direction of the drive shaft. Thus, the arc-shaped blade has a predetermined tilt angle relative to the direction perpendicular to the axial direction of the drive shaft. Furthermore, each blade of the first impeller portion 371 tilts in the direction of rotation from its lower to its upper portion.

[0120] In this disclosure, in addition to setting the inlet interface 375 on the upper side wall of the mixing section 370, the inlet interface 375 may also be set at the top of the mixing section 370, and the incoming fluid may be aligned with the blades, for example as described above, so that the first impeller section 371 is rotated by the kinetic and potential energy of the fluid.

[0121] Each blade of the second impeller section 372 is arc-shaped, and the axial angle of the arc-shaped blade can range from 5° to 85°. For example, from the upper part of the arc-shaped blade to the lower part of the arc-shaped blade (here, "up and down" refers to the position of the arc-shaped blade when it is in the working state), the angle of the arc-shaped blade gradually decreases relative to the axial direction of the drive shaft. In this way, the arc-shaped blade has a predetermined tilt angle relative to the direction perpendicular to the axial direction of the drive shaft 373. Furthermore, each blade of the second impeller section 372 tilts against the direction of rotation from the upper part of the blade to the lower part of the blade, so that the cleaning agent and cleaning liquid can be more thoroughly stirred by the second impeller section 372, which acts as a stirring device.

[0122] According to the mixing unit 370 of this disclosure, under a fixed space, the kinetic and potential energy of the incoming clean liquid can be fully utilized to complete the mixing of the liquid, thereby achieving various advantages such as low noise and low cost. Therefore, the mixing unit of this disclosure can achieve a good mixing effect without using a motor and a reduction gear.

[0123] Furthermore, the second maintenance assembly 300 may also include an airflow generating device, which may 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 a first airflow port 511. A heating device, such as a PTC heater, may be provided near the first inlet 512 to heat the airflow and form a hot airflow for drying. The airflow provided by the second airflow generating device 520 is delivered to the second inlet 522 of the base assembly 100 via a second airflow port 521, and a heating device, such as a PTC heater, may be provided near the second inlet 522 to heat the airflow and form a hot airflow for drying.

[0124] As an optional embodiment, a liquid level detection device 374 may also be provided in the mixing unit 370, wherein the liquid level detection device 374 can be used to detect the height of the liquid level in the mixing unit 370. The liquid level detection device 374 can be used to detect a lower liquid level threshold and a higher liquid level threshold in the mixing unit 370. This liquid level detection device 374 can be formed by one detector or by two or more detectors to detect the lower and higher liquid level thresholds. 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 conjunction with the first and second liquid level detection devices for verification, etc.

[0125] According to one example of this disclosure, the cleaning agent storage unit 340 is removable from the second maintenance component 300, allowing the user to replace the cleaning agent storage unit 340. For example... Figure 52As shown, a cavity 3410 for accommodating a cleaning agent reservoir 340 can be located on the second maintenance component 300. The cleaning agent reservoir 340 can also be inserted into the cavity 3410. For example, the cavity 3410 may be provided with an opening for insertion of the cleaning agent reservoir 340 (e.g., it may be located on the upper part of the second maintenance component 300). To allow locking and unlocking of the cleaning agent reservoir 340, one embodiment may also include a reset latch 3420, which engages with the locking structure of the cleaning agent reservoir 340 described below to lock and unlock the cleaning agent reservoir 340. Furthermore, a user can press the cleaning agent reservoir 340 to lock it in place or eject it from its locked position. According to one embodiment, a return spring 3430 may also be included, which can at least be used to eject the cleaning agent reservoir 340. Furthermore, the reset spring 3430 can directly contact the reset latch 3420. Preferably, an ejector 3440 can be provided, which can be disposed between the reset spring 3430 and the reset latch 3420, so that when the detergent storage section 340 is in the unlocked state, the reset latch 3420 can be lifted by the elastic force of the reset spring 3430. For example, the reset latch 3420 can be lifted by applying elastic force to the ejector 3440. In this disclosure, an ejector spring 3450 can also be provided, which can cooperate with the lifting member 3460 to eject the detergent storage section 340 from the cavity 3410.

[0126] The self-locking spring structure of the cleaning agent storage section 340 according to one embodiment of the present disclosure will now be described in detail.

[0127] Figure 52 The diagram shows the cleaning agent storage unit 340 placed within the cavity 3410. The lower part of the cavity 3410 may have an opening 3411, through which the outlet end 3401 (also referred to as the insertion end) of the cleaning agent storage unit 340 can pass to engage with the reset latch 3420 and supply cleaning agent to the mixing unit. Figure 53 As shown, the structure of the outlet end 3401 can be configured to include a guide channel and a groove, wherein the structure of the outlet end 3401 can cooperate with the protrusion 3421 of the reset latch 3420 to realize the switching between the locked state and the unlocked state. The outlet end 3401 may include a notch 3402, wherein the notch 3402 can allow the protrusion 3421 to enter.

[0128] like Figure 54As shown, the outlet end 3401 may further include a first guide channel 3403 and a limiting groove 3404. The first guide channel 3403 connects the notch 3402 and the limiting groove 3404 so that when the detergent storage section 340 is pressed, the detergent entering the protrusion 3421 from the notch 3402 will slide along the first guide channel 3403 into the limiting groove 3404, for example, it can slide along the guide wall of the first guide channel 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 guide channel 3403 extends upward from the notch 3402 to the limiting groove 3404; it may be arc-shaped and may include two sidewalls to form the channel. The first sidewall 3403a can start from the end located above the notch 3402 (at a certain distance from the notch 3402, with one end of the first sidewall 3403a offset from the center of the notch 3402, for example, offset away from the limiting groove 3404), and end at the limiting groove 3404. The second sidewall 3403b starts from the notch 3402, and its end can be located below the limiting groove 3404 (at a certain distance from the limiting groove 3404). The third sidewall 3404a of the groove corresponding to the first sidewall 3403a can be set as a straight surface (perpendicular to the horizontal plane where the boundary of the notch is located) 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, since the cleaning agent storage part 340 is fixed, the reset latch 3420 rotates.

[0129] The outlet end 3401 may further include a second guide channel 3405, which includes a fourth sidewall 3405a, a fifth sidewall 3405b, and a sixth sidewall 3405c, and is generally V-shaped. A locking groove 3405d is provided between the fourth sidewall 3405a and the fifth sidewall 3405b. When the protrusion enters the locking groove, the spring force of the return spring (described below) causes the protrusion to abut against the locking groove, thereby locking the detergent storage section 340. The outlet end 3401 may also include a non-restricting groove 3406, wherein one end of the fourth sidewall 3405a is connected to one end of the second sidewall 3403b, and the other end of the fourth sidewall 3405a is connected to one end of the fifth sidewall 3405b. The height of one end of the fourth sidewall 3405a is higher than the height of the other end of the fourth sidewall 3405a. Furthermore, the height of the other end of the fifth sidewall 3405b is higher than the height of one end of the fifth sidewall 3405b. One end of the sixth sidewall 3405c connects to one end of the third sidewall 3404a, and the other end extends to the non-restricting groove 3406. The height of one end of the sixth sidewall 3405c is lower than the height of the other end of the sixth sidewall 3405c. When the protrusion 3421 is located in the limiting groove 3404 and the detergent storage part 340 is in the locked state, if the detergent storage part 340 is pressed again, the detergent storage part 340 will drive the reset latch 3420 to move downward together. After the user completes the press, due to the rotation of the reset latch 3420 and the elastic force of the reset spring 3430, the protrusion 3421 will enter the second guide channel 3405, and through the guiding action of the sidewall of the second guide channel, as the reset latch 3420 rotates, the protrusion 3421 will enter the non-restricting groove 3406. At this point, the cleaning agent storage unit 340 will be raised to a predetermined height.

[0130] The user can then remove the detergent reservoir 340. During removal, the protrusion 3421 can slide along the third guide channel 3407 until it moves to the next notch, thereby disengaging the detergent reservoir 340 from the reset latch 3420. The third guide channel 3407 is the exit channel, which may include a seventh sidewall 3407a and an eighth sidewall 3407b. One end of the seventh sidewall 3407a can connect to the other end of the fifth sidewall 3405b, and the other end of the seventh sidewall 3407a can extend to the next notch. One end of the eighth sidewall 3407b can connect to the non-restricting groove 3406, and the other end can connect to the first sidewall of the next self-locking spring-loaded structure.

[0131] In the above embodiment, a locking structure in the self-locking springback structure is described. This locking structure can be arranged circumferentially around the outlet end 3401 so that the protrusion 3421 can enter from one locking structure to another. For example, the number of locking structures can be N, where N≥2, thus allowing the self-locking springback operation to be repeated. In this disclosure, four locking structures can be arranged around the circumference of the outlet end 3401. When the reset latch 3420 rotates 90°, it can switch from one locking structure to another, thereby allowing the self-locking springback operation to be performed again. However, the number of locking structures can also be other, such as six locking structures. With six locking structures, the reset latch 3420 rotates 60° each time to perform the next self-locking springback operation. Furthermore, in the case of four locking structures, four protrusions 3421 are correspondingly provided on the reset latch 3420; in the case of six structures, six protrusions 3421 are correspondingly provided on the reset latch 3420. The number of protrusions can be the same or different. For example, the number of protrusions can be M, where M≥2, and M can be equal to N or not equal to N. If M is not equal to N, it can be less than N. During each switch between the locked and unlocked states, the reset latch 3420 can rotate 360° / N.

[0132] During the rotation of the reset latch 3420, due to the elastic force of the reset spring 3430, when the user presses down on the detergent storage section 340 and then releases it, the reset latch 3420 is subjected to an upward elastic force due to the elastic force of the reset spring 3430 and is pushed upward (for example, through the ejector 3440). Thus, after the protrusion 3421 disengages from the locking groove, the force of the reset spring 3430 causes the protrusion 3421 to enter the third guide channel, and as the reset latch 3420 rotates, the protrusion 3421 enters the unrestricted groove 3406.

[0133] In addition, an ejector spring 3450 and a lifting member 3460 may be provided, wherein the ejector spring 3450 cooperates with the lifting member 3460 to eject at least a portion of the detergent storage section 340 to the outside of the housing. The lifting member 3460 may contact the bottom surface of the detergent storage section 340 and may pass through the cavity 3410.

[0134] According to one example of this disclosure, the reset latch 3420 can be a ring-shaped structure, for example... Figure 54As shown, the protrusion 3421 can be located on the inner annular surface of the reset latch 3420. Furthermore, a locking structure 3422 can be provided on the reset latch 3420. This locking structure 3422 can correspond to a locking groove 3412 provided in the cavity 3410. As an example, a locking groove 3412 corresponding to the locking structure 3422 can be provided on the bottom outer surface of the cavity 3410 (the surface where the outlet end 3401 is located). Figure 54 As shown, the reset latch 3420 may further include a locking structure 3422, which may be disposed on the outer annular surface of the reset latch 3420 and may be an arm extending from the outer annular surface. A locking protrusion may be provided at the end of the arm. For example, at least when the detergent storage section 340 is in the locked state, the locking protrusion may slide into the locking groove 3412 to further restrict the rotation of the reset latch 3420. The number of locking structures 3422 may be multiple, preferably the same as the number of protrusions 3421 of the reset latch 3420.

[0135] Although the above-described self-locking spring structure has been described in connection with the base station in this disclosure, those skilled in the art should understand that the self-locking spring structure can also be used in other aspects and is not limited to the base station described in this disclosure.

[0136] According to the technical solution of this disclosure, the cleaning agent storage section 340 is separately provided with the cleaning liquid storage section 350 and the recycled liquid storage section 360, and is located on the rear side adjacent to the cleaning liquid storage section 350 and the recycled liquid storage section 360. The user can lock the cleaning agent storage section 340 by simply pressing it, and unlock it by pressing it again. This eliminates the need for a release button or similar device. Although this disclosure describes the cleaning agent storage section as a liquid supply device, those skilled in the art should understand that the self-locking spring structure of this disclosure can be applied to liquid containers in other application scenarios.

[0137] The cleaning agent storage unit 340 can usually be replaced to be inserted into the second maintenance component 300, but leakage may occur in the cleaning agent storage unit 340.

[0138] In this disclosure, a two-stage check valve can be installed inside the outlet end 3401 of the cleaning agent storage section 340. The two-stage check valve can be located upstream and downstream of the fluid. The first-stage check valve can be located upstream of the fluid, while the second-stage check valve can be located downstream of the fluid. This two-stage sealing structure effectively prevents leakage.

[0139] In this disclosure, a suitable check valve can be selected to prevent leakage. Preferably, the first-stage check valve in this disclosure can be a duckbill valve, wherein the duckbill valve can be made of a soft material, such as soft rubber. The second-stage check valve can be a bead-type check valve. The bead-type check valve can include a sealing bead and a support body, wherein the sealing bead can be housed in the support body, and the support body can be housed inside the outlet end 3401.

[0140] Figure 55 An exploded view of the cleaning agent storage unit 340 is shown in the figure. Figure 56 A cross-sectional view of the detergent storage section 340 is shown. For example, a first-stage check valve 3471 in the form of a duckbill valve can be disposed inside the outlet end 3401 and located upstream, for example, near the inlet of the outlet end 3401. A second-stage check valve in the form of a sealing bead can be disposed downstream, for example, near the outlet of the outlet end 3401. The second-stage check valve 3472 may include a sealing bead 3473 and a support body 3474. The sealing bead 3473 can be made of a material such as glass. The support body can be made of a flexible material. The sealing bead 3473 disposed inside the support body can move within the support body 3474. In this disclosure, the support body 3474 can be designed with a notch, for example... Figure 55 As shown, the support body 3474 can open and close, allowing the sealing bead 3473 to move. Furthermore, a sealing structure can be provided inside the support body 3474, enabling a one-way seal when the sealing bead 3473 abuts against the sealing structure 3476. This sealing structure can be located at the lower part of the support body. The support body 3474 can be designed to limit the movement of the sealing bead 3473. For example, a limiting structure 3477 can be provided, wherein the limiting structure 3477 is configured such that when the sealing bead is lifted, it can move upstream. When the sealing bead is not lifted, the limiting structure 3477 can apply downstream pressure to the sealing bead 3473, causing the sealing bead 3473 to abut against the sealing structure, thereby achieving a sealing effect.

[0141] When the cleaning agent storage unit 340 is installed into the second maintenance component 300, the interface provided in the second maintenance component 300 or the lifting structure provided at the interface can lift the sealing bead 3473, causing the sealing bead 3473 to move upstream and disengage from the sealing structure, thereby allowing liquid to drain. Furthermore, a pump device such as a peristaltic pump can be provided in the base station to draw liquid from the cleaning agent storage unit 340. When the cleaning agent storage unit 340 is removed, the sealing bead can also perform a sealing function to prevent residual liquid from flowing out.

[0142] Typically, there is a risk of leakage when the cleaning agent storage section 340 is inverted or subjected to pressure. The solution disclosed herein employs a two-stage sealing system; if liquid leaks from the first stage seal, the presence of the second stage seal significantly reduces the risk of leakage. Furthermore, after placement into the base station, the liquid drainage is not hindered by lifting the sealing bead.

[0143] The following section will provide a detailed description of the interaction between the surface cleaning device and the base station.

[0144] During the use of the surface cleaning device, the decision to return to the base station can be determined based on factors such as the battery level, the amount of debris collected in the dust collection section, and the cleanliness of the mopping components. For example, when the battery level is low, the surface cleaning device can be controlled to return to the base station for charging. Additionally, when the cleaning fluid is insufficient, the device can be controlled to return to the base station and activate the fluid replenishment mode. Furthermore, after returning to the base station, the self-cleaning mode can be activated to clean the mopping components and collect dirt. Once the surface cleaning device is docked with the base station, its drive wheels will stop rotating. The charging contacts of both devices can then couple to charge the battery. Once docked, the self-cleaning mode, fluid replenishment mode, and / or self-draining mode can be activated.

[0145] The surface cleaning device can be used for dry and / or wet cleaning of surfaces. During dry cleaning, debris and other waste are collected into the dust collection compartment of the surface cleaning device through the cooperation of a roller brush and side brush. The dust collection compartment has a chamber that defines a storage space for storing the debris and other waste collected by the surface cleaning device, which accumulates in the storage space due to gravity. When the dust collection compartment is full of debris and other waste, it indicates that the dust collection box is full, and the airflow within the dust collection box can be restricted. Optionally, one or more capacity sensors can be installed in the dust collection compartment or in the exhaust channel of the dust collection compartment to detect the fullness of the dust collection compartment. In some embodiments, the capacity sensor may include a light emitter / detector arranged to detect when debris accumulates in the dust collection compartment to a threshold level indicating a full state. When debris accumulates in the dust collection compartment and reaches a full state, the debris at least partially obstructs the airflow, causing a decrease in pressure and a reduction in airflow velocity within the dust collection compartment. In other examples, the capacity sensor may include a pressure sensor for monitoring the pressure within the dust collection section and detecting a full collection chamber state when a threshold pressure drop occurs. In some examples, the capacity sensor may include a velocity sensor for monitoring the airflow velocity within the dust collection section and detecting a full collection chamber state when the airflow velocity is below a threshold velocity. In other examples, the capacity sensor may include an ultrasonic sensor whose signal changes according to the increase in debris density within the dust collection section, such that a full signal is only emitted when debris is compressed within the dust collection section. This prevents a full state from being triggered by lighter, looser debris extending from top to bottom within the dust collection section, even when a significant volume is still available for collecting debris and other waste. When the dust collection section is full (e.g., a full state is detected), the system can return to the base station and initiate a self-draining mode. The debris discharge suction port 15 can be opened to empty the debris into the first maintenance component 200 (e.g., when the base component 100 is used in combination with the first maintenance component 200). In some examples, when docked at a base station, the self-draining suction port 130 defined on the rear wall side of the base assembly 100 connects to the suction port 15 of the surface cleaning device, and the sealing structure provided in the ramp portion 116 can seal the corresponding position of the roller brush portion of the surface cleaning device, thereby sealing the suction nozzle of the roller brush portion. At this time, inside the surface cleaning device, the airflow path from the suction nozzle 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 debris and other waste to be discharged. According to an optional embodiment of this disclosure, an elastic baffle can be provided at the position of the base assembly 100 corresponding to the roller brush portion, so that when the surface cleaning device returns to the base assembly 100, the elastic baffle can spring up to close the suction nozzle of the roller brush portion, etc.

[0146] Before initiating the self-draining mode, the surface cleaning device can send an acknowledgment signal to the base station, indicating that the surface cleaning device has successfully docked and is ready to begin self-draining. For example, an 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, the surface cleaning device can send an infrared signal to the base station's infrared receiver. The self-draining mode can be manually initiated by the user by pressing a button on the display control unit. The self-draining mode can be locked by the processor / controller when the surface cleaning device is not docked or has not successfully docked to prevent accidental initiation. Alternatively, the self-draining mode can be automatic, so that it is controlled by the processor / controller and automatically initiated when the surface cleaning device docks and successfully docks. For example, the self-draining mode can be designed as a default setting, configured to operate after each cleaning operation of the surface cleaning device; or after a predetermined running time; or when the surface cleaning device's battery level reaches a low threshold. Furthermore, the self-draining mode can be activated before the surface cleaning device docks with the base station, and the movement of the surface cleaning device into a docking relationship with the base station can be considered part of the self-draining mode. In this case, the user can press an operable button or switch to activate the self-draining mode, and the surface cleaning device is driven to the base station and docks with it.

[0147] Before initiating self-cleaning mode, the surface cleaning device can send an acknowledgment signal to the base station, indicating that the surface cleaning device has successfully docked and is ready to begin self-cleaning. For example, an 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, the surface cleaning device can send an infrared signal to the base station's infrared receiver. Self-cleaning mode can be manually initiated by the user by pressing a button on the display control unit. When the surface cleaning device is not docked or has not successfully docked, self-cleaning mode can be locked by the processor / controller to prevent accidental initiation. Alternatively, self-cleaning mode can be automatic, controlled by the processor / controller and automatically initiated when the surface cleaning device docks and successfully docks. For example, self-cleaning mode can be designed as a default setting, configured to operate after each cleaning operation of the surface cleaning device; or after a predetermined running time; or when the surface cleaning device's battery level reaches a low threshold. Furthermore, self-cleaning mode can be initiated before the surface cleaning device docks with the base station, and the movement of the surface cleaning device into a docking relationship with the base station can be considered part of self-cleaning mode. In this situation, the user can press an operable button or switch to activate the self-cleaning mode, and the surface cleaning device is driven to the base station and docks with it.

[0148] When initiating the liquid replenishment mode, the processor / controller can activate the mode after the surface cleaning device returns to the base station and successfully docks. A retractable, flexible liquid replenishment interface can dock with the surface cleaning device's liquid replenishment port to achieve liquid replenishment. Before initiating the liquid replenishment mode, the surface cleaning device can send an acknowledgment signal to the base station, indicating that it has successfully docked and is ready to begin replenishing liquid. For example, radio frequency signals can be sent from the surface cleaning device to the base station and back; pulse signals can be sent and received through the charging channel between charging contacts. Alternatively, the surface cleaning device can send infrared signals to the base station's infrared receiver. The liquid replenishment mode can be manually activated by the user by pressing a button on the display control unit. The liquid replenishment mode can be locked by the processor / controller if the surface cleaning device is not docked or has not successfully docked to prevent accidental activation. Alternatively, the liquid replenishment mode can be automatic, controlled by the processor / controller and automatically activated when the surface cleaning device docks at the base station. For example, the liquid replenishment mode can be designed as a default setting, configured to operate after each cleaning operation of the surface cleaning device; or after a predetermined running time; or when the liquid level of the surface cleaning device reaches a low threshold or when the battery level of the surface cleaning device reaches a low threshold. The liquid replenishment mode can be initiated before the surface cleaning device docks with the base station, and the movement of the surface cleaning device into a docking relationship with the base station can be considered part of the liquid replenishment mode. In this case, the user can press a user-operable button or switch to activate the liquid replenishment mode, and the surface cleaning device is driven to the base station and docks with it to replenish the liquid.
