Description

Technical Field

[0001] This disclosure relates to a recycling storage unit and a wet surface cleaning device. Background Technology

[0002] Most existing wet surface cleaning equipment is typically upright, and this type of equipment usually combines vacuum and water washing. Upright wet surface cleaning equipment generally includes a cleaning base on which the main body is pivotally mounted. Various components of the main body, such as the vacuum motor, supply tank, recovery tank, and rechargeable battery, can be mounted on the main body. The main body is pivotally mounted on the cleaning base, and the back-and-forth movement of the cleaning base on the ground facilitates cleaning.

[0003] In recent years, a multi-purpose wet surface cleaning device has emerged, combining a wet surface cleaning unit with a portable vacuum cleaner in a vertical orientation. This multi-purpose wet surface cleaning device can be used for wet cleaning of floors, or the detachable portable vacuum cleaner can be used to clean surfaces above ground, such as tabletops, countertops, and curtains. The multi-purpose wet surface cleaning device consists of a wet surface cleaning unit and a dry vacuum cleaner unit. The wet surface cleaning unit and the dry vacuum cleaner unit are combined to form a typical upright wet surface cleaning device. Alternatively, the wet surface cleaning unit and the dry vacuum cleaner unit can be separated. The dry vacuum cleaner unit includes a suction power source and a rechargeable battery, and when used with a dust cup or other cleaning attachments, it forms a separate portable handheld vacuum cleaner.

[0004] In order for the sub-component to be used independently as a wet surface cleaning device after being detached from the support assembly, it is necessary to design a new recycling and storage unit.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0124] 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” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude 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,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0125] Figures 1 to 3 This is a structural schematic diagram of a wet surface cleaning system according to one embodiment of the present disclosure from different angles.

[0126] like Figures 1 to 3 As shown, the wet surface cleaning system 10 of this disclosure may include a cleaning base 100 in contact with the ground, a support assembly 200 mounted on the cleaning base 100, and a sub-assembly 300 selectively mounted on the support assembly 200. When the sub-assembly 300 is detached from the support assembly, the sub-assembly 300 can be used independently, for example, as part of a standalone wet surface cleaning device. In this case, the sub-assembly 300 can be connected to an accessory, and the sub-assembly 300 and the accessory constitute a wet surface cleaning device. When the sub-assembly 300 is mounted on the support assembly 200, the cleaning base 100...

[0127] Figure 4 and Figure 5 This is a schematic diagram of the structure of a cleaning base according to one embodiment of the present disclosure. Figures 6 to 9 This is a schematic diagram of the structure of a cleaning base according to another embodiment of the present disclosure. Figure 10 and Figure 11 This is a schematic diagram of the structure of the cleaning base according to the third embodiment of this disclosure.

[0128] like Figure 4 and Figure 5 As shown, the cleaning base 100 is used to clean the surface to be cleaned. The cleaning base 100 may include a cleaning module 110, which can be driven to rotate, thereby cleaning the surface to be cleaned through frictional contact between the surface of the cleaning module 110 and the surface to be cleaned.

[0129] In one embodiment, such as Figure 10 and Figure 11 As shown, the cleaning module 110 can be in the form of a roller brush. For example, the cleaning module 110 includes a first power unit 111 and a cleaning component 112. The cleaning component 112 is disposed outside the first power unit 111, for example, the cleaning component 112 wraps around the first power unit 111 and can rotate together with the first power unit 111. The first power unit 111 can be driven to rotate by the cleaning drive device 115, thereby causing the cleaning component 112 to rotate, and the relative motion between the cleaning component 112 and the surface to be cleaned is achieved through the cleaning component 112.

[0130] On the other hand, such as Figures 4 to 9 As shown, the cleaning module 110 can also be formed as a tracked structure. Specifically, the cleaning module 110 includes a first power unit 111, a second power unit 113, and a cleaning component 112, wherein the cleaning component 112 is formed as a ring and is arranged around the first power unit 111 and the second power unit 113.

[0131] In this disclosure, such as Figure 6 , Figure 9 and Figure 11 As shown, the first power unit 111 and / or the second power unit 113 can be driven to rotate by the cleaning drive device 115. Preferably, the first power unit 111 is driven to rotate by the cleaning drive device 115, and the second power unit 113 is driven to rotate by the first power unit 111 through an annular member. That is, the first power unit 111 is formed as a driving roller, and the second power unit 113 is formed as a driven roller, and the cleaning member 112.

[0132] In this disclosure, the direction of movement of the wet surface cleaning system 10 when cleaning the surface to be cleaned is forward. The second power unit 113 is located in front of the first power unit 111, and the outer diameter of the second power unit 113 is smaller than the outer diameter of the first power unit 111, so that the wet surface cleaning system 10 can clean components such as corners as much as possible.

[0133] The cleaning drive device 115 can be a motor, such as a DC motor or a stepper motor, with the DC motor preferably being a DC brushless motor.

[0134] Furthermore, the cleaning drive device 115 can drive the first power unit 111 to rotate via a speed change device 114, which can be located inside or outside the first power unit 111. When the speed change device 114 is located inside the first power unit 111, the cleaning base 100 can have a smaller volume, thereby enabling the wet surface cleaning system 10 to be adapted to cleaning surfaces in small spaces.

[0135] The cleaning drive device 115 can drive the speed change device 114 through a transmission component. The transmission component can be a belt drive component, a chain drive component, or a gear drive component, etc. The belt drive component is preferably a synchronous belt drive component.

[0136] like Figure 5 As shown, the cleaning base 100 may further include a fluid distribution module, which is used to provide a predetermined amount of cleaning liquid to the cleaning module 110 or to the surface to be cleaned near the cleaning module 110, so that the cleaning liquid is provided to the surface to be cleaned by the rotation of the cleaning module 110, so that the cleaning base 100 performs wet cleaning on the surface to be cleaned.

[0137] In this disclosure, such as Figure 4 and Figure 5 As shown, the fluid distribution module includes a liquid distribution module 121 and a vapor distribution module 122. The liquid distribution module 121 is connected to a second fluid connection interface 250, for example, to a liquid distribution connection portion of the second fluid connection interface 250. Thus, the liquid distribution module 121 can receive cleaning liquid provided by the second fluid connection interface 250 and provide the cleaning liquid to the cleaning module 110 of the cleaning base 100, or to the surface to be cleaned near the cleaning module 110 of the cleaning base 100.

[0138] Positionally, the liquid dispensing module 121 can be located inside the cleaning module or outside the cleaning module 110, for example, at the rear of the cleaning module 110. Furthermore, the outlet of the liquid dispensing module is located on or adjacent to the outer surface of the cleaning module.

[0139] The steam distribution module 122 is connected to the second fluid connection interface 250 or to the second thick film heater 125 of the cleaning base 100. For example, the steam distribution module 122 can be connected to the steam distribution connection of the second fluid connection interface 250. In this case, the first thick film heater 480 can receive the cleaning liquid stored in the cleaning liquid storage section 320, heat the cleaning liquid and generate steam. The steam is provided to the first fluid connection interface. Further, through the connection of the first fluid connection interface and the second fluid connection interface, it is transported to the steam distribution module 122. Further, the steam is provided by the steam distribution module 122 to the surface to be cleaned near the cleaning module 110 of the cleaning base 100.

[0140] On the other hand, the steam distribution module 122 can also be connected to the second thick film heater 125 and can receive the steam generated by the second thick film heater 125. In this case, the second thick film heater 125 can be connected to the second fluid connection interface 250, for example, to the liquid distribution connection part of the second fluid connection interface 250. The cleaning liquid stored in the cleaning liquid storage part 320 can be provided to the first fluid connection interface 420, for example, the cleaning liquid is provided to the liquid distribution connection part of the first fluid connection interface 420, and further provided to the second thick film heater 125 through the connection of the first fluid connection interface 420 and the second fluid connection interface 250. Of course, the cleaning liquid can also be provided to the liquid distribution module 121.

[0141] In one implementation, the liquid distribution module 121 can be a nozzle or other component, thereby enabling the spraying of cleaning liquid onto the cleaning component 112 or the surface to be cleaned near the cleaning component 112. The steam distribution module 122 can include multiple nozzles located in front of the cleaning component 112, thereby enabling the spraying of steam onto the surface to be cleaned in front of the cleaning component 112, using the steam to soften the stains on the surface to be cleaned, and improving the cleaning effect of the cleaning component 112 on the surface to be cleaned.

[0142] In this disclosure, such as Figure 5 As shown, the fluid distribution module may further include a distribution pump 124, which may be a peristaltic pump or similar structure. This peristaltic pump increases the pressure of the cleaning liquid delivered to the liquid distribution module 121, allowing the cleaning liquid to be sprayed evenly onto the cleaning component 112 or the surface to be cleaned. Furthermore, the peristaltic pump prevents backflow of the cleaning liquid in the pipeline, making the wet surface cleaning system 10 safer to use. In other words, the distribution pump 124 can be connected to a second fluid connection interface, such as a liquid distribution connection portion of the second fluid connection interface.

[0143] More preferably, such as Figure 5As shown, the fluid distribution module may further include a second thick-film heater 125 to heat the cleaning liquid into steam and supply the steam to the steam distribution module 122; of course, the second thick-film heater 125 may also be replaced by other heaters. In this disclosure, the second thick-film heater 125 may also be connected to a second fluid connection interface via a distribution pump 124, for example, to a liquid distribution connection portion of the second fluid connection interface. This distribution pump 124 may be the same as the aforementioned distribution pump 124, or a separate distribution pump 124 may be used; more preferably, when the same distribution pump 124 is used, a first switching valve is provided in the pipeline between the distribution pump 124 and the liquid distribution module 121, and a second switching valve is also provided in the pipeline connecting the distribution pump 124 and the second thick-film heater 125, so as to control the supply of cleaning liquid to the liquid distribution module 121 and / or the second thick-film heater 125 by controlling the first switching valve and the second switching valve.

[0144] In this disclosure, a third switching valve may be provided in the pipeline between the steam distribution module 122 and the steam distribution connection of the second fluid connection interface 250. Correspondingly, a fourth switching valve is also provided in the pipeline between the second thick film heater and the steam distribution module 122, so as to select different steam supply modes by controlling the third switching valve and the fourth switching valve.

[0145] The first, second, third, and fourth switching valves mentioned above can be solenoid valves or electrically operated valves, to facilitate user control of these switching valves.

[0146] When the fluid distribution module includes a second thick film heater 125, it can supply cleaning liquid only to the cleaning base. In this case, both the distribution pump 124 and the second thick film heater 125 can be connected to the second fluid connection interface 250, wherein the second fluid connection interface 250 can include only the liquid distribution connection part.

[0147] Accordingly, when the fluid distribution module does not include the second thick film heater 125, it is necessary to provide cleaning liquid to the liquid distribution module 121 and steam to the steam distribution module 122. In this case, the second fluid connection interface 250 includes a liquid distribution connection part and a steam distribution connection part. Accordingly, the liquid distribution module 121 can be connected to the liquid distribution connection part, and the steam distribution module can be connected to the steam distribution connection part.

[0148] In this disclosure, the second thick film heater 125 is arranged horizontally or substantially horizontally so that the second thick film heater 125 has a better heating effect on the cleaning liquid.

[0149] The cleaning base 100 of this disclosure may further include a dirt suction module 130, which is provided with negative pressure to collect and suck in dirt (such as dust and hair) after the cleaning module has cleaned the surface to be cleaned. This prevents the cleaning base 100 from leaving stains such as used cleaning liquid on the surface to be cleaned after cleaning. In other words, when the cleaning base 100 cleans the surface to be cleaned, it generates recycled liquid and dirt. The recycled liquid is the cleaning liquid used by the cleaning base 100 when cleaning the surface to be cleaned, and the dirt is solid debris (such as dust and hair) on the surface to be cleaned. At this time, the dirt suction module 130 forms a recycling inlet for the recycled liquid and dirt.

[0150] In one embodiment, such as Figure 7 As shown, the fluid distribution module and the dirt suction module 130 are set independently, that is, the fluid distribution module is not integrated into the dirt suction module 130. Of course, when the fluid distribution module does not supply cleaning liquid to the cleaning module 110, the wet surface cleaning system 10 can also perform dry cleaning on the surface to be cleaned.

[0151] Preferably, the dirt suction module 130 is located behind the cleaning module 110 to facilitate the recovery of liquid and dirt.

[0152] The cleaning base 100 of this disclosure may further include a housing module 140, which forms at least a portion of the outer surface of the cleaning base 100. The front end of the housing module 140 has the aforementioned spray holes, such that the front end of the housing module 140 is formed as a steam distribution module. Alternatively, the steam distribution module 122 may be formed as a separate component and mounted on the front end of the housing module 140.

[0153] The housing module 140 has a receiving space, which can also be referred to as a brush chamber, and the cleaning module 110 is located within the receiving space. When the suction source 330 is working, the receiving space is connected to the dirt suction module, forming a vacuum state, and the dirt on the surface to be cleaned and the cleaning module 110 is sucked into the recycling storage section 340.

[0154] The housing module 140 disclosed herein can also provide support for the cleaning module 110, the fluid distribution module, and the dirt suction module 130, and can also provide support for the cleaning drive device 115, transmission components, etc.

[0155] Therefore, one end of the first power unit 111 can be rotatably disposed on the housing module 140; correspondingly, when the cleaning module 110 includes the second power unit 113, that is, when the cleaning module 110 is formed as a tracked cleaning component, one end of the second power unit 113 can also be rotatably disposed on the housing module 140.

[0156] Meanwhile, the other end of the first power unit 111 can be rotatably disposed on the bracket portion 170. When the bracket portion 170 is disposed on the housing module 140, the first power unit 111 is located in the brush chamber.

[0157] Approximately, when the cleaning module 110 includes a second power unit 113, that is, when the cleaning module 110 is formed as a tracked cleaning component, the other end of the second power unit 113 can also be rotatably disposed on the bracket portion 170. When the bracket portion 170 is installed on the housing module 140, the first power unit 111 and the second power unit 113 are located in the brush chamber.

[0158] Furthermore, at least a portion of the transmission device 114 slides into the interior of the first power unit 111, thereby achieving a mechanical connection between the transmission device 114 and the second power unit 113.

[0159] The belt drive assembly may include a drive synchronous pulley 116, which is mounted on the cleaning drive device 115 and driven to rotate by the cleaning drive device 115. In this disclosure, the cleaning drive device 115 and the drive synchronous pulley 116 are located on opposite sides of the housing module 140. Specifically, the cleaning drive device 115 is located inside the housing module 140, and the drive synchronous pulley 116 is located outside the housing module 140.

[0160] The active synchronous pulley 116 drives the driven synchronous pulley 117 to rotate. The driven synchronous pulley 117 is mounted on one end of the transmission shaft. The transmission shaft is rotatably disposed on the housing module 140, and the transmission shaft forms the input shaft of the speed change device 114, or the transmission shaft can input driving force to the speed change device 114.

[0161] In this disclosure, an isolation portion 180 is provided between the dirt suction module 130 and the liquid distribution module 121. At least a portion of the isolation portion 180 is located in the receiving space, thereby isolating the dirt suction module 130 and the liquid distribution module 121 to prevent the cleaning liquid distributed by the liquid distribution module 121 from being directly sucked into the dirt suction module 130. As one implementation, the isolation portion 180 is formed in the form of a scraper; and the other end of the isolation portion 180 can contact the cleaning component 112; of course, the isolation portion 180 can also be positioned at a predetermined distance from the cleaning component 112.

[0162] The cleaning module 110 may further include a mounting connector module 150, which is pivotally disposed on the housing module 140, such that when the support assembly 200 is connected to the mounting connector module 150, the support assembly 200 is pivotable relative to the cleaning base 100, and more specifically, the support assembly 200 is pivotable relative to the cleaning module 110 of the cleaning base 100.

[0163] The cleaning base 100 may also include a moving wheel module 160, which is connected to the housing module 140. When the wet surface cleaning system 10 is working, the moving wheel module 160 contacts the surface to be cleaned and rolls on the surface to be cleaned, so as to reduce the power required for the wet surface cleaning system 10 to move and also effectively prevent the cleaning base from contaminating the already cleaned surface.

[0164] like Figures 1 to 3 As shown, the wet surface cleaning system 10 of this disclosure may further include a support assembly 200, which is pivotally mounted to the cleaning base 100 and in fluid communication with the cleaning base 100.

[0165] Specifically, the support assembly 200 may include a support platform 210 and a platform column 220. The platform column 220 is disposed on the support platform 210. The lower surface of the support platform 210 and the upper surface of the cleaning base 100 are longitudinally spaced, thereby creating a space between the support platform 210 and the cleaning base 100. The support platform 210 can rotate at a large angle relative to the cleaning base, allowing the cleaning base 100 to extend into a low space. For example, the lower end of the platform column 220 is disposed on the support platform 210, and the support platform 210 extends forward from the lower end of the platform column 220. The support platform 210 can be connected to the aforementioned mounting connector module 150, thereby enabling pivoting between the support assembly 200 and the cleaning base 100.

[0166] A handle 230 is connected to the upper end of the platform column 220. In this disclosure, the handle 230 is retractably mounted on the platform column 220. For example, the position of the handle 230 can be adjusted by inserting it to different depths into the platform column 220. When the wet surface cleaning system 10 of this disclosure is in use, the user can operate the wet surface cleaning system 10 by operating the handle 230. In this disclosure, the handle 230 can be equipped with buttons for controlling the wet surface cleaning system 10, such as a power switch button, a working mode selection button, etc. When the user triggers the power switch button, the wet surface cleaning system 10 can be turned on or off. Or, when the user triggers the working mode selection button, the power of the suction source, cleaning drive device 115, distribution pump and / or first thick film heater 480 can be controlled.

[0167] In this disclosure, the platform column 220 may include a front shell and a rear shell, which cooperate to form a cavity between them. At least a portion of the handle 230 can be inserted into the cavity, thereby achieving a telescopic connection between the handle 230 and the platform column 220; after the position of the handle 230 is adjusted, the handle 230 can be fixed to the platform column 220 by fasteners such as screws.

[0168] The handle 230 includes an elongated rod 231, one end of which is connected to a platform column, and the other end of which is connected to a handle 232, so that the handle 230 is formed by the handle 232 and the rod 231. In this disclosure, the handle 232 is formed in the shape of a racetrack, or the handle 232 may also be formed in other shapes that are convenient to hold.

[0169] When the wet surface cleaning system 10 is not in working mode, the platform column 220 can be in a vertical state, and thus the platform column 220 can have an upper end and a lower end.

[0170] like Figures 1 to 3 As shown, the wet surface cleaning system 10 of this disclosure may further include a sub-component 300, which is detachably mounted on the support component 200. When the sub-component 300 is detached from the support component 200, the sub-component 300 can be used independently, for example, as part of an independent wet surface cleaning device. In this case, the sub-component 300 can be connected to an accessory, and the sub-component 300 and the accessory together form a wet surface cleaning device.

[0171] Figure 12 This is a schematic diagram of a wet surface cleaning system according to one embodiment of the present disclosure.

[0172] Specifically, such as Figure 12 As shown, the sub-component 300 is detached from the support component 200 by lifting the sub-component 300 from the support component 200; conversely, the sub-component 300 is installed onto the support component 200 in a top-to-bottom direction.

[0173] As the sub-component 300 separates from the support component 200, the user can carry the sub-component 300 and connect accessories, such as cleaning head components and brushes, to the interface portion 390 of the sub-component 300 for various cleaning operations.

[0174] In this disclosure, the sub-component 300 can be disposed on the support platform 210 of the support component 200, thereby enabling the wet surface cleaning system 10 to form a complete structure when the sub-component 300 is installed on the support component 200.

[0175] The sub-component 300 may include components such as a main body 310, wherein the main body 310 forms the outer contour of the wet surface cleaning device. In this disclosure, the main body 310 may be a cubic or cylindrical component, and the main body 310 is capable of housing the cleaning liquid storage unit 320 and the recovery storage unit 340. That is, a portion of the outer surface of the main body 310 forms a portion of the outer contour of the sub-component 300.

[0176] The main body 310 forms the frame of the sub-component 300, and other components of the sub-component 300 can be directly or indirectly fixed to the main body 310, thereby making the sub-component 300 a whole.

[0177] like Figures 1 to 3 As shown, the sub-component 300 may further include a cleaning liquid storage unit 320, a suction source 330, and a recovery storage unit 340.

[0178] The cleaning liquid storage section 320 is disposed on the main body 310 and is used to store cleaning liquid. When the sub-component 300 is installed on the support component 200, the cleaning liquid storage section 320 is used to provide cleaning liquid to the cleaning base 100. For example, the cleaning liquid in the cleaning liquid storage section 320 can be provided to the cleaning module 110 or to the surface to be cleaned near the cleaning module 110, so that the cleaning base 100 performs wet cleaning on the surface to be cleaned based on the cleaning liquid provided by the cleaning liquid storage section 320.

[0179] Figure 13 This is a cross-sectional structural schematic diagram of a cleaning liquid storage unit according to one embodiment of the present disclosure.

[0180] The cleaning liquid storage unit 320 defines a chamber for storing a certain amount of cleaning liquid supply, which may be formed as a water tank structure to store cleaning liquid within the cleaning liquid storage unit 320.

[0181] like Figure 13 As shown, the cleaning liquid storage unit 320 may include a solution tank 321, a filling cap 322, and a valve assembly 323. The filling cap 322 may be disposed at the inlet of the solution tank 321, thereby allowing cleaning liquid to be injected into the solution tank 321. Conversely, the valve assembly 323 may be disposed at the lower end of the solution tank 321. The main body 310 is provided with a receiver. When the cleaning liquid storage unit 320 is disposed on the main body 310, the valve assembly 323 of the cleaning liquid storage unit 320 cooperates with the receiver of the main body 310. For example, at least a portion of the receiver may be disposed inside the valve assembly 323, thereby allowing the cleaning liquid stored in the cleaning liquid storage unit 320 to be supplied externally through the valve assembly 323 and the receiver. In a preferred embodiment, the cleaning liquid storage unit 320 can be selectively removed from the sub-assembly 300 by means of a latch.

[0182] In this disclosure, the cleaning liquid may include one or more suitable cleaning liquids, including but not limited to water, concentrated cleaning agents, diluted cleaning agents, etc. Preferably, the cleaning liquid includes a mixture of water and concentrated cleaning agents.

[0183] Figure 15 This is a schematic diagram of the structure of a recycling storage unit 340 according to one embodiment of the present disclosure. Figure 16 and Figure 17 This is another structural schematic diagram of a recycling storage unit according to one embodiment of the present disclosure. Figure 18 This is a cross-sectional structural schematic diagram of a recycling storage unit according to one embodiment of the present disclosure. Figure 19 This is a schematic diagram of the structure of a filter according to one embodiment of the present disclosure. Figure 20 This is a schematic diagram of the structure of a cover assembly according to one embodiment of the present disclosure.

[0184] like Figures 15 to 20 As shown, the recycling storage unit 340 of this disclosure may include structures such as a recycling container 341, a hollow riser 342, and a filter 343.

[0185] The recycling container 341 has an open top and a closed first bottom wall 3411; thus, the recycling container 341 can form a space for storing liquid, that is, it forms a liquid storage space.

[0186] Accordingly, the recycling container 341 includes a side wall 3412 extending from the first bottom wall 3411 to the open top, wherein the filter 343 is spaced apart from the first bottom wall 3411 of the recycling container 341, so that when the base 3432 of the filter 343 is formed with filter holes, the liquid flowing out of the filter 343 enters the liquid storage space of the recycling container 341.

[0187] At least a portion of the hollow riser 342 is isolated from the inner cavity of the recycling container 341, that is, the hollow riser 342 and the recycling container 341 of this disclosure can be formed as separate components; of course, as a preferred implementation, the hollow riser 342 can also be integrally formed with the recycling container 341. For example, when the recycling storage part 340 is formed of plastic material, the recycling container 341 and the hollow riser 342 can be integrally formed.

[0188] One end of the hollow riser 342 communicates with the inner cavity of the recycling container 341; thus, the outlet of the hollow riser 342 defines the inlet for connection between the hollow riser 342 and the top of the recycling container 341. At this time, the hollow riser 342 can be connected to the first recycling connection 410 to transfer the recycled liquid and dirt (solid-liquid mixture) after the cleaning base 100 has cleaned the surface to be cleaned to the recycling container 341.

[0189] The solid-liquid mixture enters the inner cavity of the recovery container 341 through one end of the hollow riser 342 and is filtered by the filter 343. The liquid in the solid-liquid mixture is stored in the inner cavity of the recovery container 341, while the solid in the solid-liquid mixture is retained in the filter 343.

[0190] In this disclosure, the filter 343 is detachably installed inside the recycling container 341. The filter 343 has a portion operably connected to the recycling container 341, so that after the solid-liquid mixture enters the recycling storage section 340, it is filtered by the filter 343, and the dirt is retained inside the filter 343, and the recycled liquid is stored in the recycling container 341.

[0191] The portion of the filter 343 operably connected to the recycling container 341 includes a coupling portion 3431 adapted to the side wall 3412 of the recycling tank, thereby operably connecting the filter 343 to the recycling container 341. In other words, the coupling portion 3431 is adapted to operably connect the filter 343 to the recycling container 341.

[0192] The filter 343 includes a flat or substantially flat base 3432, and in this disclosure, at least a portion of the base 3432 is formed with a through-hole to form a filter hole. Accordingly, the size of the filter hole can be set to prevent solid waste from passing through.

[0193] In one implementation, the recycling container 341 includes an extension 3413 that extends from the side wall 3412 of the recycling container 341 in a direction away from the side wall 3412 of the recycling container 341. The inlet of the hollow riser 342 is connected to the extension 3413, thereby allowing the middle part of the hollow riser 342 to maintain a certain distance from the outer wall of the recycling container 341.

[0194] In this disclosure, the recycling container 341 further includes a second bottom wall 3414, through which the outlet of the hollow riser 342 passes and is located inside the recycling container 341. The second bottom wall 3414 is positioned higher than the first bottom wall 3411, thereby allowing the solid-liquid mixture transported by the hollow riser 342 to be conveyed into the upper space of the recycling container 341.

[0195] Accordingly, the filter 343 forms a filtration space, and the solid-liquid mixture flowing out of the outlet of the hollow riser 342 can flow into the filtration space of the filter 343, thereby separating the solid and liquid components of the solid-liquid mixture within the filtration space.

[0196] More preferably, the outlet of the hollow riser 342 is higher than the upper opening of the filtration space of the filter 343, so that the solid-liquid mixture transported through the hollow riser 342 can flow into the filtration space of the filter 343 under the action of gravity.

[0197] In this disclosure, the recycling container 341 further includes a third bottom wall 3415, at least a portion of the filter 343 contacting the third bottom wall 3415 to restrict the vertical position of the filter 343 by means of the third bottom wall 3415. That is, the inner surface of the third bottom wall 3415 is formed as part of the structure for fixing the coupling portion 3431 of the filter 343.

[0198] Preferably, the third bottom wall 3415 and the side wall of the recycling container 341 form a receiving portion, whereby the coupling portion 3431 can be accommodated within the receiving portion. Preferably, the size of the receiving portion is slightly smaller than that of the coupling portion 3431, so that when the filter 343 is installed in the recycling container 341, the side wall of the receiving portion can apply a certain positive pressure to the coupling portion 3431, and thus the filter 343 can be firmly fixed to the recycling container 341.

[0199] Of course, the outer surface of the filter 343 may also have a slide rail or groove formed in the vertical direction; correspondingly, the side wall of the recycling container 341 may have a groove or slide rail corresponding to the slide rail or groove in the vertical direction, thereby restricting the lateral movement of the filter 343 and thus fixing the position of the filter 343.

[0200] In this disclosure, the recycling storage unit 340 further includes a cover assembly 344, which is detachably disposed on the recycling container 341. The cover assembly 344 at least partially surrounds the open top of the recycling container 341 and defines the air outlet of the recycling container 341. It is in fluid communication with the suction source 330, that is, when the suction source 330 is working, it can apply negative pressure to the recycling storage unit 340. This negative pressure is applied to the cleaning base 100 through the hollow riser 342 to achieve the suction of the solid-liquid mixture.

[0201] More preferably, the recycling storage unit 340 further includes a secondary filtration assembly 345, which is detachably connected to the cover assembly 344. The secondary filtration assembly 345 is located upstream of the air outlet along the gas flow direction from the recycling container 341 to the suction source, so that the gas filtered by the secondary filtration assembly 345 can be drawn to the suction source 330.

[0202] As one implementation, the secondary filter assembly 345 can be selected as a structure such as HEPA, thereby removing liquids from the air and improving the dryness of the air.

[0203] In this disclosure, the cover assembly 344 includes a gas inlet 3441. When the cover assembly 344 is disposed on the recycling container 341, the gas inlet 3441 of the cover assembly 344 is disposed away from the filter 343, thereby making the distance from the hollow riser 342 to the gas inlet of the cover assembly 344 as long as possible.

[0204] In a preferred embodiment, a baffle 3442 is provided at the lower part of the cover assembly 344. The baffle 3442 at least partially covers the gas inlet 3441 of the cover assembly 344 and is located at least partially between the gas inlet 3441 and the filter 343, thereby preventing gas from directly entering the gas inlet of the cover assembly 344.

[0205] Figure 14 This is a schematic diagram of the piping connections of a wet surface cleaning system according to one embodiment of the present disclosure.

[0206] like Figure 14 As shown, the suction source 330 is disposed on the main body 310. The suction source 330 is used to generate suction. When the sub-component 300 is installed on the support component 200, the suction source 330 is connected to the cleaning base 100 so that the recovered liquid and dirt after the cleaning base 100 cleans the surface to be cleaned are sucked into the recovery storage unit 340.

[0207] Specifically, the suction source 330 may include a motor bracket and a vacuum motor. The motor bracket may be disposed inside the main body 310, and the vacuum motor is disposed on the motor bracket and is capable of providing rotational power. The vacuum motor is equipped with a fan, and the vacuum motor drives the fan to rotate so that the suction source 330 can generate a vacuum, and the suction of recovered liquids and dirt is achieved through this vacuum.

[0208] The recycling storage unit 340 is disposed in the main body 310 and is used to store recycled liquids and contaminants. The recycling storage unit 340 of this disclosure may include a tank with an open top, which is closed by a lid, thereby defining a recycling chamber for receiving the aforementioned recycled liquids and contaminants. Additionally, the recycling storage unit 340 can be selectively removed from the sub-assembly via a latch to dispose of the recycled liquids and contaminants to a suitable container or from a waste discharge port.

[0209] When the sub-component 300 is installed on the support component 200, the recovered liquid and dirt drawn by the suction source 330 are stored in the recovery storage section 340.

[0210] The cleaning liquid storage unit 320 and the recovery storage unit 340 of this disclosure are detachably mounted on both sides of the main body 310. For example, the cleaning liquid storage unit 320 and the recovery storage unit 340 are located on both sides of the transverse direction of the main body 310, which is a horizontal direction perpendicular or substantially perpendicular to the travel path of the wet surface cleaning system 10 when cleaning the surface to be cleaned. Moreover, a portion of the outer surface of the cleaning liquid storage unit 320 is formed as a portion of the outer surface of the sub-assembly 300, and a portion of the outer surface of the recovery storage unit 340 is also formed as a portion of the outer surface of the sub-assembly 300. Thus, the outer shell of the main body 310, the cleaning liquid storage unit 320, and the recovery storage unit 340 together define the front wall, side wall, and rear wall of the sub-assembly, making the sub-assembly 300 a generally cubic component; those skilled in the art will understand that other shapes are also possible.

[0211] The sub-component 300 may further include a rechargeable battery module 360, which is disposed inside the main body 310 and near the rear of the main body 310. In other words, the rechargeable battery module 360 ​​is located further rearward of the main body 310 relative to the cleaning liquid storage unit 320 and the recycling storage unit 340. In one embodiment, the rechargeable battery module 360 ​​is not higher than either the cleaning liquid storage unit 320 or the recycling storage unit 340.

[0212] The rechargeable battery module 360 ​​disclosed herein can provide power to the suction source 330, enabling the suction source 330 to operate normally. On the other hand, the rechargeable battery module 360 ​​can also provide power to the cleaning base 100. For example, the rechargeable battery module 360 ​​can provide power to the distribution pump 124 and the second thick film heater 125 of the cleaning base 100, and can also provide power to the cleaning drive device 115 of the cleaning base 100.

[0213] Specifically, the sub-component 300 may include a first circuit interface 470, which is connected to the rechargeable battery module 360. The support component 200 includes a second circuit interface 270. When the sub-component 300 is disposed on the support component 200, the first circuit interface 470 and the second circuit interface 270 are connected so that the rechargeable battery module 360 ​​provides power to the cleaning base 100.

[0214] Preferably, one of the first circuit interface 470 and the second circuit interface 270 can be formed as a socket and the other as a pin, so that the circuit connection between the first circuit interface and the second circuit interface can be realized through the cooperation of the socket and the pin.

[0215] In this disclosure, the first circuit interface 470 and the second circuit interface 270 can also be formed in the form of contacts or gold fingers. Those skilled in the art should know that as long as the first circuit interface 470 and the second circuit interface 270 are connected by circuitry, it is sufficient.

[0216] On the other hand, considering that the sub-component 300 and the support component 200 can be connected by a circuit through the second electrical element 500 and the first electrical element 440, the rechargeable battery module 360 ​​can also provide power to the cleaning base 100 through the connection between the second electrical element 500 and the first electrical element 440.

[0217] Positionally, the rechargeable battery module 360 ​​is disposed inside the main body 310 and near the rear of the main body 310; more specifically, the rechargeable battery module 360 ​​is located at the rear of the recycling storage section 340 and / or the cleaning liquid storage section 320. Furthermore, the suction source 330 is disposed inside the main body 310 and near the rear of the main body 310; in other words, the suction source 330 is closer to the rear of the main body 310 than the cleaning liquid storage section 320 and the recycling storage section 340. More preferably, the suction source 330 is located at the rear of the recycling storage section 340 and / or the cleaning liquid storage section 320. In one embodiment, the suction source 330 is not higher than either the cleaning liquid storage section 320 or the recycling storage section 340.

[0218] In this disclosure, the rechargeable battery module 360 ​​may be located above the suction source 330. Of course, those skilled in the art should know that the rechargeable battery module 360 ​​may also be located to the side of the suction source 330.

[0219] The sub-component 300 may also include a handle 350 disposed on the top wall of the main body 310 and extending laterally to facilitate the user to install the sub-component 300 onto the support component 200 or to detach the sub-component 300 from the support component 200.

[0220] Preferably, the plane containing the handle of the handle 230 is orthogonal to the plane containing the lifting handle 350.

[0221] As one implementation, the handle 350 includes a grip extending above the sub-assembly 300.

[0222] In this disclosure, such as Figure 3As shown, the upper wall of the sub-component 300 has a recess 355, which corresponds to the position of the grip and is spaced at a predetermined distance from the grip. In particular, the grip is formed as an upwardly protruding structure, so that when the user holds the grip, the user's hand can easily pass through the area between the grip and the upper wall of the sub-component 300, thereby making it easy to grip the grip.

[0223] like Figures 1 to 3 As shown, the sub-component 300 may further include a latching assembly, at least a portion of which is located on the sub-component 300. For example, at least a portion of the latching assembly may be located on the main body 310 of the sub-component 300, and the latching assembly is used to lock the sub-component 300 to the support assembly 200. In this disclosure, when the sub-component 300 is mounted on the support assembly 200, at least a portion of the latching assembly is hidden. For example, the latching assembly may include a latch button 370, a portion of which is displayed when the sub-component 300 is mounted on the support assembly 200, thus hiding other parts of the latching assembly. More preferably, at least a portion of the latch button 370 is located on the upper wall of the sub-component 300 and on one side of the handle 350, so that when the user holds the handle, the user's thumb can trigger the latch button 370 and unlock the latching assembly. The latch button 370 is configured to allow a user to selectively remove the sub-assembly 300 from the support assembly 200 for use as a portable wet surface cleaning device. When the latch button 370 is triggered, for example by pressing the latch button 370, the sub-assembly 300 is allowed to be removed from the wet surface cleaning system 10. At this time, the sub-assembly 300 can be lifted upward by holding the handle to detach it from the support assembly 200. Conversely, when the latch button 370 is not triggered, the sub-assembly 300 is not allowed to be removed from the wet surface cleaning system 10, thereby making the wet surface cleaning system 10 safer to use.

[0224] like Figure 3 As shown, the sub-component 300 also includes a function button 380, at least a portion of which is located on the upper wall of the sub-component 300 and on the other side of the handle 350. The function button 380 can be a self-cleaning start button, meaning that when the kinetic button is triggered, the wet surface cleaning system 10 can perform self-cleaning.

[0225] Of course, a display device (not shown in the figure) can also be provided on the upper wall of the sub-component 300 to display the status of the wet surface cleaning equipment, such as the battery status of the wet surface cleaning equipment and the status of the cleaning liquid in the cleaning liquid storage unit 320, so as to facilitate the user to charge and replenish the cleaning liquid of the wet surface cleaning system 10 in a timely manner. Alternatively, the display device can also display the status of the wastewater in the recovery storage unit 340, so as to facilitate the timely emptying of the wastewater in the recovery storage unit 340. Of course, the display device can also be provided on the side wall of the sub-component 300.

[0226] like Figure 14 As shown, the sub-assembly also includes an interface portion 390, which can be disposed on the front sidewall of the main body portion 310 to facilitate the user connecting other components, such as flexible hoses of accessories, to the interface portion 390; more preferably, the interface portion 390 can be opened or closed by a pivotable interface cover 391, especially, as Figure 1 As shown, the interface cover 391 can seal the interface portion 390.

[0227] Specifically, the interface portion 390 can be connected to one end of a flexible hose, thereby enabling the interface portion 390 to form an inlet for the flexible hose of the accessory; wherein, the interface portion 390 can be selectively connected to a suction source 330, a cleaning liquid storage unit 320, or a recovery storage unit 340.

[0228] In other words, the interface section 390 includes multiple sub-interfaces, for example... Figure 14 The interface 390 includes three sub-interfaces. One of the sub-interfaces can be connected to the suction source 330 to achieve the suction of recycled liquid and dirt through the sub-interface. Correspondingly, one of the sub-interfaces can be connected to the cleaning liquid storage unit 320 to provide cleaning liquid to the outside through the sub-interface.

[0229] Accordingly, the flexible conduit of the accessory also includes multiple sub-conduits, such as sub-conduits for the flow of cleaning liquid, sub-conduits for the flow of steam, and sub-conduits for the flow of recycled liquid and contaminants. These sub-conduits are respectively connected to corresponding sub-interfaces. For example, the sub-conduit for the flow of cleaning liquid can be connected to a sub-interface connected to the cleaning liquid storage unit; the sub-conduit for the flow of steam can be connected to a sub-conduit connected to the first thick film heater 480 of the sub-assembly 300; and the sub-conduit for the flow of recycled liquid and contaminants can be connected to a sub-interface connected to the recycling storage unit 340 of the sub-assembly 300.

[0230] In this disclosure, the sub-component 300 may further include a first thick-film heater 480 for heating the cleaning liquid into steam. In this case, the first thick-film heater 480 is connected to the cleaning liquid storage unit 320, thereby enabling it to receive the cleaning liquid provided by the cleaning liquid storage unit 320 and heat the cleaning liquid into steam.

[0231] At this time, one of the sub-interfaces can also be connected to the first thick film heater 480 of the sub-component 300, thereby enabling the supply of steam to the outside through the sub-interface.

[0232] When the sub-assembly 300 is used alone, an accessory (e.g., a cleaning nozzle assembly) is selectively mounted on the other end of the flexible hose; and at least one sub-port is connected via the flexible hose, for example, the flexible hose can be connected to a suction source 330 via the sub-port, and the flexible hose can also be connected to at least one of the cleaning liquid storage section 320 and the first thick film heater 480 of the sub-assembly 300. Accordingly, the interior of the flexible hose may include multiple independent channels.

[0233] The flexible hose can be connected to different accessories, i.e., different cleaning nozzle assemblies, to achieve different cleaning functions, such as cleaning curtains, decorations, crevices, and other surfaces that are not suitable for cleaning with traditional upright wet surface cleaning equipment.

[0234] In this disclosure, the sub-component 300 may further include an AC / DC converter 395 for converting mains power into DC power of a preset voltage and providing it to the first thick film heater 480 of the sub-component 300.

[0235] In this disclosure, when the sub-component 300 is disposed on the support component 200, it is necessary to realize the fluid connection and / or circuit connection between the sub-component 300 and the support component 200.

[0236] Specifically, the sub-component 300 may include a first recycling connection 410, to which the suction source 330 can be connected. Correspondingly, the support component 200 includes a second recycling connection 240. When the sub-component 300 is operably mounted on the support component 200, the first recycling connection 410 is connected to the second recycling connection 240, so that the suction source 330 communicates with the cleaning base 100 through the first recycling connection 410 and the second recycling connection 240.

[0237] Preferably, at least one of the first recycling connection portion 410 and the second recycling connection portion 240 is provided with a sealing ring so that a sealed connection can be achieved between the first recycling connection portion 410 and the second recycling connection portion 240.

[0238] At this time, when the suction source 330 is in working condition and generates negative pressure, it can suck up the recovered liquid and dirt from the dirt suction module 130 of the cleaning base 100. The recovered liquid and dirt can be transported to the recovery storage unit 340 through the first recovery connection 410 and the second recovery connection 240. That is, the suction source 330 is connected to the recovery storage unit 340 to apply negative pressure to the recovery storage unit 340. The recovery storage unit 340 is connected to the first recovery connection 410 so that the recovered liquid and dirt passing through the first recovery connection 410 can directly enter the recovery storage unit 340.

[0239] The sub-component 300 further includes an airflow outlet 430, which is fluidly connected to the outlet of the suction source 330. The airflow outlet 430 is configured to ensure that airflow discharged through the airflow outlet 430 does not pass through the support assembly 200 when the sub-component 300 can be operably mounted on the support assembly 200.

[0240] In this disclosure, the airflow outlet 430 may be disposed toward the side wall of the sub-assembly 300. On one hand, the side wall of the sub-assembly 300 may be provided with an exhaust port to discharge the gas discharged from the airflow outlet 430 to the outside of the sub-assembly 300 through the exhaust port. On the other hand, the gas discharged through the airflow outlet 430 may also be discharged to the outside of the sub-assembly 300 through the gap between the cleaning liquid storage section 320 and the main body section 310, or through the gap between the recovery storage section 340 and the main body section 310.

[0241] The wet surface cleaning system 10 further includes a second electrical component 500, which can be selectively connected to mains power via an electrical connection line. In this disclosure, the second electrical component 500 can be a charging contact or a power supply contact. The sub-component 300 includes a first electrical component 440. When the sub-component 300 is installed on the support component, the first electrical component is electrically connected to the second electrical component 500, such that the horizontal plane of the second electrical component 500 and the first electrical component 440 is higher than the horizontal plane of the first fluid connection interface 420 and the second fluid connection interface 250. Therefore, the cleaning liquid overflowing from the first fluid connection interface 420 and the second fluid connection interface 250 will not affect the circuit connection between the second electrical component 500 and the first electrical component 440.

[0242] The cleaning liquid storage unit 320 can be connected to the first fluid connection interface 420 via a delivery pump 490, thereby enabling the cleaning liquid to be delivered to the first fluid connection interface 420 via the delivery pump 490 and further delivered to the cleaning base.

[0243] Furthermore, the cleaning liquid storage unit 320 can be connected to the first thick film heater 480 via a delivery pump 490, thereby enabling the cleaning liquid to be delivered to the first thick film heater 480 via the delivery pump 490 and further heated by the first thick film heater 480.

[0244] The second electrical component 500 is disposed on the platform column 220, and the first electrical component 440 is disposed on the rear side of the main body 310 of the sub-component 300. When the sub-component 300 is installed on the support component, the second electrical component 500 and the first electrical component 440 are aligned, thereby forming a circuit connection between the second electrical component 500 and the first electrical component 440.

[0245] In this disclosure, the sub-component 300 may further include a first fluid connection interface 420, which, when the sub-component 300 is operatively mounted on the support component 200, is connected to a second fluid connection interface 250 to provide cleaning liquid and / or steam to the cleaning base 100 through the first fluid connection interface 420 and the second fluid connection interface 250.

[0246] More preferably, the first fluid connection interface 420 includes a liquid dispensing connection and / or a steam dispensing connection; the second fluid connection interface 250 includes a liquid dispensing connection and / or a steam dispensing connection.

[0247] For example, when the sub-component 300 includes a first thick film heater 480, the steam generated by the first thick film heater 480 can be supplied to the steam distribution module of the cleaning base, and further, the steam can be provided to a first fluid connection interface 420, wherein the first fluid connection interface 420 may include a steam distribution connection portion.

[0248] However, when the sub-component 300 does not include the first thick film heater 480, the first fluid connection interface 420 and the second fluid connection interface 250 may not include the steam distribution connection, but only include the liquid distribution connection, so that the cleaning liquid in the cleaning liquid storage section 320 can be provided to the cleaning base 100 or the surface to be cleaned near the cleaning base through the liquid distribution connection.

[0249] In this disclosure, the sub-component 300 may further include a diversion valve 460, which may be a three-way valve. The diversion valve 460 is connected to the cleaning liquid storage section 320 and may include a first interface and a second interface. The first interface is connected to the interface section 390, and the second interface is connected to the second fluid connection interface 250. The diversion valve 460 is configured to: when the sub-component 300 is installed on the support assembly, allow fluid to flow in the pipelines where the first fluid connection interface and the second fluid connection interface 250 are located, but do not allow fluid to flow in the pipeline where the interface section 390 is located; when the sub-component 300 is detached from the support assembly, do not allow fluid to flow in the pipelines where the first fluid connection interface and the second fluid connection interface 250 are located, but allow fluid to flow in the pipeline where the interface section 390 is located.

[0250] The diversion valve 460 can be configured in multiple ways. For example, the cleaning liquid storage unit 320 is connected to a diversion valve, thereby enabling the cleaning liquid storage unit 320 to selectively supply cleaning liquid to the cleaning base 100 when the sub-assembly 300 is installed on the support assembly 200, and to selectively supply cleaning liquid to the accessories when the sub-assembly 300 is removed from the support assembly 200.

[0251] Similarly, the first thick film heater 480 of the sub-assembly 300 is connected to a diverter valve, thereby enabling the first thick film heater 480 to selectively supply steam to the cleaning base 100 when the sub-assembly 300 is installed on the support assembly 200, and to selectively supply steam to the accessories when the sub-assembly 300 is removed from the support assembly 200.

[0252] More preferably, the suction source 330 of the sub-assembly 300 can also be connected to a diversion valve, thereby enabling: when the sub-assembly 300 is installed on the support assembly 200, the suction source 330 to selectively provide negative pressure to the cleaning base 100; and when the sub-assembly 300 is removed from the support assembly 200, the cleaning liquid storage section 320 to selectively provide negative pressure to the attachment.

[0253] The diversion valve 460 can be controlled by an actuator to switch between different fluid paths; in other words, the actuator can selectively block the line supplying cleaning liquid, steam, or negative pressure to the cleaning base. For example, when the sub-assembly 300 is removed from the support assembly 200, the actuator is actuated to block the lines supplying cleaning liquid, steam, and negative pressure to the cleaning base.

[0254] More preferably, the actuator can selectively cooperate with the presence signal of the sub-assembly 300, thereby blocking the pipeline that provides cleaning liquid to the cleaning base, the pipeline that provides steam, or the pipeline that provides negative pressure after the sub-assembly 300 is detached from the support assembly 200, and guiding the fluid to the interface 390.

[0255] Accordingly, the actuator can also selectively block the lines supplying cleaning liquid, steam, or negative pressure to the accessory, i.e., block each sub-port. For example, when the sub-assembly 300 is mounted on the support assembly 200, the actuator is driven to block the lines supplying cleaning liquid, steam, or negative pressure to the accessory.

[0256] In one case, the actuator can cooperate with the actuation part of the connection end of the flexible hose. In this case, when the connection end of the flexible hose is connected to the interface 390, the pipeline that provides cleaning liquid, steam, or negative pressure to the cleaning base is blocked, and the fluid is guided to the interface 390.

[0257] In another embodiment, the wet surface cleaning system 10 may include an in-situ detection device, which may be a Hall sensor or a limit switch, etc. When the sub-assembly 300 is mounted on the support assembly 200, the in-situ detection device is triggered. At this time, the actuator is driven to block the pipeline supplying cleaning liquid, steam, or negative pressure to the accessory, and to open the pipeline supplying cleaning liquid, steam, or negative pressure to the cleaning base 100. Conversely, when the in-situ detection device is not triggered, the actuator is driven to block the pipeline supplying cleaning liquid, steam, or negative pressure to the cleaning base, and to open the pipeline supplying cleaning liquid, steam, or negative pressure to the accessory.

[0258] In this disclosure, the bottom surface of the sub-component is formed in a generally square or circular shape, and the first recycling connection part 410, the first electrical component 440, the first circuit interface 470 and the second fluid connection interface 250 can all be disposed on the bottom surface of the sub-component 300.

[0259] Accordingly, the support platform 210 of the support assembly 200 is formed as an inverted cone-shaped body with a generally square or circular cross-section, and there is a longitudinal gap between the lower end face of the inverted cone-shaped body (i.e. the lower surface of the support platform 210) and the upper surface of the cleaning base 100. Accordingly, the second recycling connection, the second electrical component, the second circuit interface and the first fluid connection interface can all be disposed on the upper wall of the support platform 210.

[0260] The wet surface cleaning system 10 disclosed herein allows for the operative installation of a sub-assembly 300 into or detachable from a support assembly 200 before operation, enabling its use as a stand-alone wet surface cleaning device. When the sub-assembly 300 is installed into the support assembly 200, various connections, including but not limited to fluid transport interconnections, recovery interconnections, and electrical system interconnections, can be simultaneously established between the component systems.

[0261] More specifically, when the sub-component 300 is operably mounted to the support assembly 200, the cleaning liquid storage unit 320 is connected to the fluid distribution module of the cleaning base 100, thereby allowing the cleaning fluid (liquid and / or gas and / or gas-liquid mixture) to be distributed to the cleaning module 110 and / or the floor surface. The recovery storage unit 340 is connected to the dirt suction module 130 of the cleaning base 100, thereby allowing the vacuum airflow generated by the suction source 330 to be drawn into the recovery storage unit 340 through the dirt suction module 130. Furthermore, the first circuit interface 470 and the second circuit interface 270 of the sub-component 300 are connected to transmit electrical energy to the cleaning drive device, fluid distribution module, or second thick film heater 125, etc., of the cleaning base 100.

[0262] In one scenario, the AC mains power supply is directly connected to the rechargeable battery module of the sub-component 300 via a power cord and an AC / DC converter, so that the AC mains power can simultaneously power the cleaning base 100 and the sub-component 300. In this case, the AC / DC converter can be located on the support component 200 to enable various cleaning functions.

[0263] The user fills the cleaning liquid reservoir 320 with at least one cleaning liquid. To store cleaning liquid in the cleaning liquid reservoir 320, the cleaning liquid reservoir 320 can be removed from the sub-assembly 300, then filled with cleaning liquid, and then installed on the side of the sub-assembly 300, thereby enabling the cleaning liquid reservoir 320 to be connected to the first fluid interface.

[0264] To operate the wet surface cleaning system 10 in floor cleaning mode, with the sub-assembly 300 mounted on the support assembly 200, the user actuates the main power switch on the handle or the sub-assembly to draw power from a power source (such as the sub-assembly's rechargeable battery module or a room outlet) to power the suction source 330. The negative pressure generated by the suction source 330 then passes through the recovery storage unit 340 to generate a working airflow. Furthermore, when the sub-assembly 300 is mounted on the support assembly 200, power is supplied to the cleaning base 100 through the sub-assembly 300. As described above, the sub-assembly 300 and the cleaning base 100 are electrically connected via a mating first and second circuit interface.

[0265] The power supplied from sub-assembly 300 can power electrical components including the first thick film heater 480, brushed motor, brushless motor, PCB board, pump, lighting, LED / LCD display, speaker, and sensor.

[0266] With the system powered on and the sub-component 300 positioned on the support component 200, the user grasps the handle and moves the wet surface cleaning system 10 along the surface to be cleaned. Cleaning fluid at room temperature or high temperature is dispensed to the ground or cleaning base 100 while the cleaning module rolls relative to the surface to be cleaned.

[0267] By incorporating sensors such as vision sensors, ultrasonic sensors, TOF sensors, and infrared sensors, the cleaning fluid and suction power can be selectively allocated based on the interaction between the sensors and ground obstacles and materials. Used cleaning fluid and dirt on the surface to be cleaned are drawn into the working airflow and removed through the dirt suction module on the cleaning base. The fluid then flows through the fluid channel into the recovery storage unit 340, where it is separated from the working air. Solid and liquid dirt are further separated by a solid-liquid separator within the recovery tank. The working air continues to flow out of the recovery storage unit 340 along the working air exhaust channel and reaches the suction source 330. Exhaust gas from the suction source 330 continues to flow out of the exhaust port of the sub-assembly 300, preferably facing the ground, to reuse the exhaust gas for rapid drying of the surface.

[0268] Users can remove the recycling storage unit 340 from the side of the sub-assembly 300 and empty the recycling bin in a suitable location to dispose of used cleaning fluids and waste into appropriate containers and drains.

[0269] In order to operate the wet surface cleaning system 10 in a portable assisted cleaning mode, the user removes the sub-component 300 from the support assembly 200 by pressing the latch button on the sub-component 300 or the support assembly 200.

[0270] When the sub-component 300 is removed from the support assembly 200, the cleaning liquid storage unit 320, suction source 330, recovery storage unit 340, and first thick film heater 480 can all communicate with the interface unit 390 of the sub-component 300. The first and second circuit interfaces of the sub-component 300 and the support assembly 200 are separated, thereby disconnecting the power to the cleaning base 100.

[0271] To prevent accidental operation by the user, the suction source 330 stops working when the latch button is triggered. Furthermore, there is no fluid interaction between the second fluid connection port 250 and the interface portion until the user installs the attached flexible hose and presses the start switch again.

[0272] When the sub-component 300 needs to work independently, the user installs the flexible hose of the accessory to the interface 390 of the sub-component 300 and turns on the switch. There is fluid interaction inside the interface 390, which can provide cleaning liquid and / or steam to the accessory and draw out the used recycled liquid and dirt from the accessory and draw it into the recycling storage section 340.

[0273] Therefore, the wet surface cleaning system 10 disclosed herein can be configured as a multi-purpose wet surface cleaning system, providing unlimited application possibilities for traditional upright wet surface cleaning equipment. The sub-component is compact and lightweight, thus simplifying its use.
