[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] Figure 1 This is a schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure.

[0119] like Figure 1 As shown, the surface cleaning device of this disclosure may include components such as a cleaning base 100, a main body 200, a connecting part 300, a recovery and storage part 400, a gas-liquid separator 500, and a suction device 600. Furthermore, the components such as the recovery and storage part 400, the gas-liquid separator 500, and the suction device 600 of this disclosure can be referred to as a recovery system.

[0120] The cleaning base 100 is configured to move on the surface to be cleaned, and as the cleaning base 100 moves on the surface to be cleaned, the surface to be cleaned can be cleaned.

[0121] Figure 2 This is a schematic diagram of the structure of a cleaning base according to one embodiment of the present disclosure.Figure 3 This is a structural schematic diagram of the clean base from another angle according to one embodiment of the present disclosure. Figure 4 This is a partial structural schematic diagram of a cleaning base according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of the structure of a liquid distribution system 140 according to one embodiment of the present disclosure.

[0122] like Figure 2 to Figure 5 As shown, the cleaning base 100 of this disclosure may include a longitudinal direction and a transverse direction. Taking the cleaning base 100 moving on and cleaning a generally horizontal surface as an example, the forward and backward movement direction of the cleaning base 100 is the longitudinal direction, and the transverse direction is a horizontal direction perpendicular to or substantially perpendicular to the longitudinal direction. In other words, both the longitudinal direction and the transverse direction of this disclosure can be horizontal.

[0123] The cleaning base 100 may include a seat member 110, on which a traveling mechanism 120 may be mounted to allow the cleaning base 100 to move on the surface to be cleaned. The traveling mechanism 120 may include two rollers, which may be disposed at the rear of the seat member 110 in the longitudinal direction and at the two ends in the transverse direction, thereby providing support for the seat member 110. In this embodiment, since the cleaning member 170 of the cleaning base 100 can also contact the surface to be cleaned and at least partially support the seat member 110 when cleaning, the cleaning member 170 and the two rollers provide support for the seat member 110.

[0124] In another embodiment, the walking mechanism 120 may include four rollers located at the four corners of the portion of the seat member 110 near the surface to be cleaned. Accordingly, the four rollers can provide stable support for the seat member 110. At this time, when the cleaning member 170 contacts the surface to be cleaned, the positive pressure between the cleaning member 170 and the surface to be cleaned can be adjusted and controlled.

[0125] The base component 110 is also provided with a cleaning liquid storage section 130. That is, unlike the prior art, the cleaning liquid storage section 130 of this disclosure is part of the cleaning base 100. The cleaning liquid storage section 130 stores water or cleaning fluid, and the water or cleaning fluid stored in the cleaning liquid storage section 130 can be supplied to the cleaning component 170 through the liquid distribution system 140. Moreover, since the surface cleaning device of this disclosure includes the cleaning liquid storage section 130, it is capable of wet cleaning of the surface to be cleaned; accordingly, it can also be referred to as a wet surface cleaning device.

[0126] In one specific embodiment, the cleaning liquid storage section 130 is located in the rear half of the cleaning base 100. In other words, the cleaning liquid storage section 130 can be disposed above the seat member 110 and located in the rear part of the seat member 110 in the longitudinal direction.

[0127] Preferably, the cleaning liquid storage unit 130 of this disclosure can be removed from the base member 110 by pulling it backward. That is, when the amount of cleaning liquid in the cleaning liquid storage unit 130 is small, the cleaning liquid storage unit 130 can be removed by pulling it backward, and after water or cleaning liquid is added back into the cleaning liquid storage unit 130, the cleaning liquid storage unit 130 can be installed on the base member 110 by pushing it forward.

[0128] The cleaning base 100 disclosed herein may further include a cover portion 150; the cover portion 150 is disposed on the seat member 110 and located at the front of the seat member 110 in the longitudinal direction. The cover portion 150 and the front end of the seat member 110 together form a receiving space, in which a cleaning member 170 can be disposed. In a preferred embodiment, the cover portion 150 can be detached from the seat member 110, thereby facilitating cleaning of the cover portion 150, and correspondingly, facilitating cleaning of the cleaning base 100 as well.

[0129] The cover portion 150 has a first end and a second end in the circumferential direction. The first end in the circumferential direction of the cover portion 150 is formed as a free end, and the second end in the circumferential direction of the cover portion 150 is disposed near the upper surface of the seat member 110 and has a predetermined distance from the upper surface of the seat member 110.

[0130] A suction port 190 is formed on the seat component 110, which is located behind the cleaning component 170. A cleaning component 160 is provided above the seat component 110. At least a portion of the cleaning component 160 extends out from the preset interval and can contact the fibers of the cleaning component 170 to scrape off the dirt attached to the cleaning component 170. After the dirt is scraped off by the cleaning component 160, it will enter the recycling storage section 400 through the suction port 190 under the action of gravity and the negative pressure adsorption of the suction port 190.

[0131] The cleaning component 170 is detachably disposed on the seat component 110, and at least a portion of the cleaning component 170 is located within the receiving space. The cleaning component 170 of this disclosure is rotatable and achieves cleaning of the surface to be cleaned through frictional contact with the surface to be cleaned during its rotation.

[0132] The cleaning component 170 disclosed herein can be implemented using structures in the prior art, which will not be described in detail here.

[0133] In this disclosure, the liquid distribution system 140 may include a water pump 141 and a distribution component 142. The water pump 141 is used to draw cleaning liquid from the cleaning liquid storage section 130 and pressurize the cleaning liquid to supply it to the distribution component 142. The distribution component 142 is disposed on the seat component 110 and located behind the cover portion 150. The lower end of the distribution component 142 is located above the cleaning component 160. At least a portion of the liquid supplied through the distribution component 142 can be discharged to the cleaning component 160 and supplied to the cleaning component 170 via the cleaning component 160.

[0134] Figure 6 This is a structural schematic diagram of a portion of the clean base according to one embodiment of the present disclosure from another angle. Figure 7 yes Figure 6 Enlarged schematic diagram of part A. Figure 8 This is a schematic diagram of the structure of a distribution component (part) according to one embodiment of the present disclosure. Figure 9 yes Figure 8 Enlarged schematic diagram of part B. Figure 10 This is a structural schematic diagram of the distribution component from another angle according to one embodiment of the present disclosure.

[0135] Specifically, the dispensing component 142 includes a base portion 142A, which has a front surface and a rear surface. A liquid dispensing channel 142C is formed on the rear surface of the base portion 142A. Liquid pressurized by the water pump 141 can be supplied to the liquid dispensing channel 142C and dispensed by it. In a preferred embodiment, the liquid dispensing channel 142C has multiple ends, and a drain hole 142D is formed at each end of the liquid dispensing channel 142C. Accordingly, multiple drain holes 142D are provided, and the drain holes 142D are disposed through the base portion 142A, thereby allowing cleaning liquid to flow to the front surface of the base portion 142A through the drain holes 142D.

[0136] The front surface of the base portion 142A is provided with rib structures 142B; in this disclosure, the rib structures 142B can be distributed at approximately equal intervals along the length direction of the base portion 142A (i.e., along the transverse direction of the clean base portion 100), thereby forming a liquid distribution space between two adjacent rib structures 142B.

[0137] In one specific embodiment, a portion of the rib structure 142B is correspondingly provided with the drain hole 142D, and at least a portion of the rib structure 142B corresponding to the drain hole 142D is spaced apart from the front surface of the base portion 142A, thereby the drain hole 142D can communicate with the liquid distribution space on both sides of the rib structure 142B, so that cleaning liquid can be discharged to the liquid distribution space through the drain hole 142D.

[0138] In one specific embodiment, the connection between the drain hole 142D and the liquid distribution space is located at a corner of the liquid distribution space, wherein... Figure 8 Taking the directions shown as an example, some of these connections are located in the upper left corner of the liquid distribution space, and some are located in the upper right corner of the liquid distribution space.

[0139] A flow guiding structure 142E is provided on the rib structure 142B. The flow guiding structure 142E is configured to guide the liquid discharged from the drain hole 142D to the middle region of the liquid distribution space in the lateral direction.

[0140] Furthermore, the liquid distribution space includes a rear sidewall 142F, which is formed as part of the front surface of the base portion 142A. The rear sidewall 142F is inclined forward in the lateral direction away from the flow guiding structure 142E, thereby enabling the liquid entering the liquid distribution space to be discharged to the front of the liquid distribution space as quickly as possible and to flow out of the liquid distribution space from the front end of the liquid distribution space.

[0141] In addition, the liquid distribution space also includes a bottom wall 142G, which is configured as a V-shaped surface, and the bottom wall 142G gradually descends and then gradually rises in the lateral direction, thereby including a low region, which is located approximately in the middle of the liquid distribution space in the lateral direction, so as to form a liquid flow path through the low region.

[0142] Furthermore, the bottom wall 142G slopes downwards in a rear-to-front direction, allowing the cleaning liquid to flow forward on the bottom wall 142G under the influence of gravity and to the cleaning member 160. At this time, at least a portion of the cleaning member 160 (e.g., the portion located below the dispensing member 142) is inclined downwards in a rear-to-front direction, allowing the cleaning liquid to be supplied to the cleaning member 170 via the cleaning member 160 under the influence of gravity.

[0143] In this disclosure, the redesigned liquid distribution system enables the cleaning liquid to be distributed more evenly on the cleaning component, effectively avoiding uneven drying and wetting on the cleaning component 170 and improving the cleaning effect of the surface cleaning equipment of this disclosure.

[0144] Figure 11 This is a structural schematic diagram of a partial structure of a surface cleaning device according to one embodiment of the present disclosure. Figure 12 This is a schematic diagram of the structure of a recycling storage unit and a suction device according to one embodiment of the present disclosure. Figure 13 This is a structural schematic diagram of the recycling storage unit and the suction device according to one embodiment of the present disclosure from another angle.

[0145] like Figure 1 and Figure 11 to Figure 13 As shown, the cleaning base 100 of this disclosure is operably connected to the main body 200. Specifically, in this disclosure, the cleaning base 100 further includes a support 180, which can be fixed to the seat member 110; a connecting portion 300 is rotatably provided on the support 180. In one embodiment, the connecting portion 300 is rotatable relative to the support 180, and the axis of rotation of the connecting portion 300 relative to the support 180 is a straight line extending in the lateral direction. Simultaneously, there is a preset height between this axis of rotation and the surface to be cleaned.

[0146] The lower end of the main body 200 is fixed to the connecting part 300, thereby allowing the main body 200 to rotate relative to the cleaning base 100. Correspondingly, on the one hand, the main body 200 can be self-supported against the cleaning base 100, where the cleaning base 100 is set approximately horizontally and the main body 200 is set approximately vertically, or the main body 200 is tilted forward, meaning that in the projection of the main body 200 onto the horizontal plane, the upper end of the main body 200 is closer to the front of the surface cleaning device (cleaning base) than the lower end. On the other hand, the main body 200 can be supported on the surface to be cleaned in a flattened posture (lying down posture / lying-down state), where the flattened posture means that the axis of the main body 200 is parallel to the horizontal plane, or the angle between the axis of the main body 200 and the horizontal plane is approximately 0-5°, thereby allowing at least a portion of the rear surface of the main body 200 to approach the surface to be cleaned.

[0147] The main body 200 of this disclosure has a height direction. Specifically, when the main body 200 is in an upright state and is set approximately vertically, this vertical direction is the height direction (axial direction) of the main body 200. Unless otherwise specified, the following height direction refers to the height direction of the main body 200.

[0148] In one specific embodiment, the main body 200 may be formed as a frame structure so that the main body 200 can accommodate components such as the recovery storage unit 400, the gas-liquid separator 500, and the suction device 600.

[0149] In this disclosure, when the recycling storage unit 400 is mounted on the main body 200, the recycling storage unit 400 forms part of the upper surface of the surface cleaning device. In a preferred embodiment, the upper surface of the recycling storage unit 400 is formed as part of the upper surface of the surface cleaning device. The side surface of the recycling storage unit 400 is formed as part of the side surface of the surface cleaning device, and the rear surface of the recycling storage unit 400 is formed as part of the rear surface of the surface cleaning device.

[0150] In particular, when the recycling and storage unit 400 is mounted on the main body 200, the upper surface of the main body 200 and the upper surface of the solid-liquid separation device 420 together form the upper surface of the surface cleaning device. In other words, the main body 200 includes a first upper surface, the recycling and storage unit 400 includes a second upper surface, and when the recycling and storage unit 400 is mounted on the main body 200, the first upper surface and the second upper surface together form the upper surface of the surface cleaning device.

Figure 16 This is a structural schematic diagram of a solid-liquid separation apparatus according to one embodiment of the present disclosure from another angle.

[0152] like Figure 14 to Figure 16 As shown, in a specific embodiment, the recycling storage unit 400 includes a housing 410 and a solid-liquid separation device 420; wherein, a sewage pipe 411 is provided inside the housing 410, and a through hole is provided on the bottom wall of the housing 410. The inlet of the sewage pipe 411 is connected to the through hole, and the sewage pipe 411 can be connected to the suction port 190 of the cleaning base 100 through a pipe, so that when a negative pressure is applied to the recycling storage unit 400, the mixture of dirt and cleaning liquid can be sucked into the recycling storage unit 400 through the pipe and the sewage pipe 411 and stored in the recycling storage unit 400.

[0153] The upper end of the housing portion 410 of this disclosure is open, and the solid-liquid separation device 420 is disposed in the housing portion 410. At least a portion of the solid-liquid separation device 420 is located inside the housing portion 410 and at least a portion is located outside the housing portion 410. Accordingly, the upper surface of the solid-liquid separation device 420 is formed as part of the upper surface of the surface cleaning device.

[0154] Figure 15 This is a schematic diagram of a solid-liquid separation apparatus according to one embodiment of the present disclosure. Figure 16 This is a structural schematic diagram of a solid-liquid separation apparatus according to one embodiment of the present disclosure from another angle.

[0155] like Figure 15 and Figure 16 As shown, the solid-liquid separation device 420 of this disclosure includes an upper component 421, and a sealing part is provided around the periphery of the upper component 421. When the solid-liquid separation device 420 is installed on the housing part 410, the upper opening of the housing part 410 is sealed by the cooperation between the sealing part and the inner circumferential surface of the housing part 410.

[0156] Furthermore, the solid-liquid separation device 420 also includes a lower component 422, which is spaced apart from the upper component 421 and connected by a connecting plate 423. A filter structure 424 is provided on the lower surface of the lower component 422, wherein a sealing ring is provided around a portion of the lower component 422 and around the filter structure 424. Thus, a sealed space can be formed by the lower component 422, the filter structure 424, and the inner wall of the housing 410. When solid dirt and cleaning liquid are transported into the sealed space through the sewage pipe, the cleaning liquid can be filtered through the filter structure 424, and the solid dirt is retained in the sealed space, thereby achieving solid-liquid separation of dirt.

[0157] Figure 17 This is a schematic diagram of the structure of a first latch and a second latch according to one embodiment of the present disclosure. Figure 18 This is a schematic diagram of the structure of the first operating unit according to one embodiment of the present disclosure. Figure 19 This is a schematic diagram of the structure of an actuating member according to one embodiment of the present disclosure.

[0158] The solid-liquid separation device 420 disclosed herein further includes a first latch 425 for locking the solid-liquid separation device 420 at the opening of the housing portion 410; wherein the first latch 425 has a first operable stroke to unlock the solid-liquid separation device 420 from the housing portion 410; specifically, the first latch 425 of this disclosure includes a first operating part 425A, which can be formed in the form of a button. In this disclosure, when downward pressure is applied to the first operating part 425A, the first operating part 425A moves downward, causing the two claws 425B of the first latch 425 to retract, thereby enabling the solid-liquid separation device 420 to unlock from the housing portion 410.

[0159] Conversely, the inner wall of the housing 410 has a latch. When the first operating part 425A is not operated, under the action of the spring's restoring force, the first operating part 425A will move upward or be held at the maximum upward displacement. As a result, the two claws 425B of the first latch 425 extend out and are at least partially located in the latch of the housing 410, thereby locking the solid-liquid separation device 420 to the housing 410.

[0160] The solid-liquid separation device 420 disclosed herein further includes a housing portion 427, which is disposed on the upper member 421, such that at least a portion of the first latch 425 is located within the housing portion 427. In this disclosure, the upper surface of the housing portion 427 is formed as part of the upper surface of a surface cleaning device, and a through hole is provided on the upper surface of the housing portion 427. At least a portion of the first operating part 425A is located within the through hole of the housing portion 427 to facilitate user operation of the first operating part 425A. In a preferred embodiment, when the first operating part 425A is in its maximum upward position, the upper surface of the first operating part 425A can be flush with or substantially flush with the upper surface of the housing portion 427.

[0161] In this disclosure, the first latch 425 has a first operable stroke; wherein, the first operable stroke of the first latch 425 can be the downward movement stroke of the first operating part 425A.

[0162] The solid-liquid separation device 420 may further include an actuating member 426 operably connected to a first latch 425 so that, when the first latch 425 is actuated, the actuating member 426 can move outward relative to the upper member 421. That is, when the first operating part 425A is driven to move downward, the actuating member 426 can move to the left (to... Figure 17 direction shown).

[0163] Additionally, the surface cleaning apparatus of this disclosure may also include a second latch 700, which can be disposed on the main body 200. Moreover, the second latch 700 has a second operable stroke to unlock the recycling storage unit 400 from the main body 200; when the recycling storage unit 400 is installed on the main body 200, the first operable stroke is limited by the second operable stroke.

[0164] Specifically, the second latch 700 includes a second operating part 710 and a locking hook 720, wherein the second operating part 710 is configured to move up and down relative to the main body 200. In a preferred embodiment, the second operating part 710 and the locking hook 720 may be integrally formed, and when the second operating part 710 is subjected to a downward external force and moves downward, the second operating part 710 and the locking hook 720 move downward together, thereby releasing the recovery storage part 400.

[0165] Specifically, when the second operating part 710 is in its maximum upward position, the locking hook 720 can pass through the housing part 427 and is at least partially located within the housing part 427. Furthermore, the locking hook 720 can engage with the side wall of the housing part 427 to lock the recycling storage part 400 onto the main body 200. When the second operating part 710 is in its maximum downward position, the locking hook 720 can disengage from the side wall of the housing part 427, thereby unlocking the recycling storage part 400 from the main body 200.

[0166] The main body 200 of this disclosure has a through hole on its upper surface, and at least a portion of the second operating part 710 is located within the through hole of the main body 200 to facilitate user operation of the second operating part 710. In a preferred embodiment, when the second operating part 710 is in its maximum upward position, the upper surface of the second operating part 710 can be flush with or substantially flush with the upper surface of the main body 200 (i.e., the first upper surface).

[0167] The second operable stroke can be the downward movement stroke of the second operating unit 710. Correspondingly, the first operable stroke being limited by the second operable stroke means that the first operable stroke cannot be started when the second operable stroke has not started.

[0168] Based on the above structure, in this disclosure, when the second operating part 710 is at its maximum upward position and the recycling storage part 400 is mounted on the main body 200, the actuating member 426 can be obstructed by the second latch 700, thereby limiting the first operable stroke. Specifically, the actuating member 426 can be restricted by the locking hook 720, so when the user presses down on the first operating part 425A, since the locking hook 720 does not allow the actuating member 426 to move to the left (outward), the first operating part 425A cannot move downward to the position where the first latch 425 is opened. At this time, the first latch 425 cannot be opened, and further, the solid-liquid separation device 420 cannot be disassembled from the housing part 410.

[0169] In other cases, when the recycling storage unit 400 is not installed on the main body 200, the movement of the actuating member 426 is not restricted. At this time, when the first operating unit 425A is driven and moves downward, the first latch 425 can be opened and the solid-liquid separation device 420 can be released. At the same time, an upward force is applied to the solid-liquid separation device 420, which can separate the solid-liquid separation device 420 from the housing 410.

[0170] In one specific embodiment, the actuating member 426 includes a push rod having a free end and an operating end opposite the free end; the operating end is operatively connected to a first operating portion 425A of the first latch 425. More specifically, the first operating portion 425A includes an actuation groove, in which at least a portion of the operating end of the push rod is located to provide an actuating force to the operating end of the push rod when the first operating portion 425A is actuated, thereby enabling the actuating member 426 to move to the left (outward) when the first operating portion 425A moves downward.

[0171] In this disclosure, the operating end of the push rod includes a first actuating surface 426A and a second actuating surface 425A1 formed in the actuating groove. When the first operating part 425A is operated, the first actuating surface 426A and the second actuating surface 425A1 cooperate to slide, thereby driving the push rod to move; wherein, both the first actuating surface 426A and the second actuating surface 425A1 are inclined surfaces.

[0172] Accordingly, when the recycling storage unit 400 is installed on the main body 200, the free end is operably restricted by at least a portion of the second latch 700 to restrict the movement of the push rod; specifically, the latch 720 of the second latch 700 abuts against the free end of the push rod to restrict the movement of the push rod.

[0173] Therefore, in the surface cleaning device of this disclosure, the cooperation of the first latch 425 and the second latch 700 can effectively prevent the solid-liquid separation device from being improperly disassembled, thereby effectively preventing damage to the surface cleaning device.

[0174] See again Figure 11 and Figure 19 The surface cleaning device disclosed herein also includes a rechargeable battery 800, which provides operating power for the surface cleaning device. Specifically, the rechargeable battery 800 can provide electrical energy to the cleaning base 100 (e.g., components such as the water pump and cleaning parts of the cleaning base 100), the suction device 600, the gas-liquid separator 500, etc.

[0175] Furthermore, the suction device 600 of this disclosure can be fixed to the main body 200 and used to provide vacuum suction (negative pressure) from the cleaning base 100 to the recycling storage section 400. That is to say, after the suction device 600 of this disclosure applies negative pressure to the recycling storage section 400, the negative pressure can be provided to the suction port 190 of the cleaning base 100. Dirt and recycled liquid can enter the recycling storage section 400 through the suction port 190 and the pipe under the action of the negative pressure and be stored in the box section 410 of the recycling storage section 400.

[0176] The gas-liquid separator 500 disclosed herein can be fixed to the main body 200 and is at least partially disposed inside the recovery storage section 400. That is, when the recovery storage section 400 is located on the main body 200, at least a portion of the gas-liquid separator 500 is located inside the recovery storage section 400, thereby filtering the liquid passing through the gas-liquid separator 500 and keeping the gas between the gas-liquid separator 500 and the suction device 600 as dry as possible, or in other words, keeping the gas entering the suction device 600 as dry as possible.

[0177] In other words, in the direction of gas flow, the gas-liquid separator 500 can be located upstream of the suction device 600. Gas flowing out of the recovery storage section 400 first undergoes gas-liquid separation in the gas-liquid separator 500 before entering the inlet of the suction device 600 and then exiting from the outlet of the suction device 600. In this case, the inlet of the suction device 600 is connected to the outlet of the gas-liquid separator 500.

[0178] In this disclosure, the suction device 600 and the rechargeable battery 800 are positioned on the main body 200 closer to the cleaning base 100 than the gas-liquid separator 500. As a result, compared to the prior art, the surface cleaning device of this disclosure has a lower center of gravity, which makes it easier and less strenuous for the user to operate.

[0179] In addition, the surface cleaning device disclosed herein can be used in a reclining position, which makes operation more effortless.

[0180] In a preferred embodiment, the rechargeable battery 800 is closer to the cleaning base 100 than the suction device 600. This design takes into account that surface cleaning devices generally require a long battery life, and the rechargeable battery 800 is correspondingly heavier. Therefore, placing the rechargeable battery 800 at a lower position will lower the center of gravity of the surface cleaning device of this disclosure.

[0181] Furthermore, since the rechargeable battery 800 is connected to the component that requires power via a cable, it is most reasonable to place the rechargeable battery 800 at the position closest to the cleaning base 100. This will not affect the position of other components of the surface cleaning equipment, such as the recycling storage unit 400, the gas-liquid separator 500, and the suction device 600.

[0182] In a preferred embodiment, the recovery storage unit 400 and the suction device 600 are arranged opposite each other in the front-rear direction of the main body 200; relatively speaking, the recovery storage unit 400 is located on the rear side of the main body 200, while the suction device 600 is located on the front side of the main body 200, so that when the surface cleaning device of the present disclosure is laid down, the liquid disturbance in the recovery storage unit 400 is minimized; at this time, when the main body 200 is supported on the surface to be cleaned in a flat state, one surface (rear surface) of the recovery storage unit 400 is set close to the surface to be cleaned, and the gas-liquid separator 500, the suction device 600 and the rechargeable battery 800 are all far away from the surface to be cleaned relative to the recovery storage unit 400.

[0183] In this disclosure, the gas-liquid separator 500 includes a rotatable impeller, the axis of rotation of which is perpendicular to the axis of rotation of the suction device 600, or the axis of rotation of the impeller intersects the axis of rotation of the suction device 600 at an obtuse angle. Thus, in the surface cleaning device of this disclosure, the rotation axes of the two motors are arranged in such a way that the vibration of the entire surface cleaning device can be reduced and the user experience can be improved.

[0184] Preferably, the extension line of the rotating shaft of the suction device 600 does not pass through the impeller, and the impellers of the suction device 600 and the gas-liquid separator 500 are staggered in the front-to-back direction, thereby making the arrangement of the components of the surface cleaning device of this disclosure more reasonable and reducing the volume of the surface cleaning device.

[0185] In some embodiments, at least a portion of the solid-liquid separation device 420 is located between the gas-liquid separator 500 and the suction device 600 in the height direction. Thus, the recovery storage section 400 of this disclosure can have an overlap portion with the gas-liquid separator 500 and the suction device 600 in the height direction, and correspondingly, the size of the main body 200 in the height direction can be reduced.

[0186] In a preferred embodiment, when the main body 200 is supported on the surface to be cleaned in a flat position, at least a portion of the wastewater pipe 411 is located below the suction device 600; and at least a portion of the wastewater pipe 411 is located below the rechargeable battery 800. Thus, the recycling storage section 400 of this disclosure can have an overlap portion with the rechargeable battery 800 and the suction device 600 in the height direction, and correspondingly, the size of the main body 200 in the height direction can be reduced.

[0187] Figure 20 This is a schematic diagram of a surface cleaning device in a flat (lying) state according to one embodiment of the present disclosure.

[0188] like Figure 20As shown, the surface cleaning device of this disclosure also includes an operating handle 900, which is detachably connected to the main body 200 via a connecting rod 910 (the connecting rod 910 is straight and can also be referred to as an upright connecting rod). The connecting rod 910 is arranged such that, in the height direction of the main body 200, its extension passes sequentially through the gas-liquid separator 500, the suction device 600, and the rechargeable battery 800, without passing through the recycling storage section 400. Preferably, the connecting rod 910 is detachably connected to the first upper surface of the main body 200.

[0189] In other words, in this disclosure, the connection point between the connecting rod 910 and the main body 200 is located at the front of the upper surface of the surface cleaning device, and correspondingly, the recycling storage unit 400 is located at the rear of the main body 200, while the gas-liquid separator 500, the suction device 600, and the rechargeable battery 800 are located at the front of the main body 200.

[0190] The surface cleaning device disclosed herein is easier to operate due to the position setting of the operating handle 900. In particular, the center of gravity of the surface cleaning device is lower during cleaning operations, which improves the user experience.

[0191] Furthermore, when the surface cleaning device of this disclosure is in a lying position, the connecting rod 910 is located away from the surface to be cleaned, thereby making it easier to lay the surface cleaning device of this disclosure flat, thus enabling cleaning operations in low-ceilinged spaces.

[0192] Figure 21 This is a schematic diagram of the structure of a surface cleaning device according to another embodiment of the present disclosure. Figure 22 yes Figure 21 Enlarged schematic diagram of part C.

[0193] like Figure 21 and Figure 22 As shown, the surface cleaning device of this disclosure may further include a sliding support 950. In this case, the operating handle 900 may include a hand grip, which is configured to facilitate holding. In other words, the hand grip is formed as part of the operating handle 900 for controlling the posture of the surface cleaning device by holding the hand grip.

[0194] like Figure 22 As shown, a sliding support 950 is provided on the handheld part. When the main body 200 is in a flat state relative to the cleaning base 100, the sliding support 950 contacts the flat surface to be cleaned and can slide to support the handheld part, so that the main body 200 does not contact the flat surface to be cleaned.

[0195] Therefore, one end of the main body 200 of the surface cleaning device disclosed herein (i.e., the front end in the flat state and the lower end in the upright state) can be supported by the cleaning base 100, and the other end of the main body 200 of the surface cleaning device (i.e., the rear end in the flat state and the lower end in the upright state) can be supported by the sliding support 950. Thus, when the main body 200 is in the flat state, the main body 200 and the components such as the recycling storage section 400, the gas-liquid separator 500, the suction device 600 and the rechargeable battery 800 installed on the main body 200 can all form support with the flat surface to be cleaned.

[0196] By positioning the sliding support 950 of the surface cleaning device disclosed herein further back, the surface cleaning device in a lying position can be supported more stably. Moreover, since the rearwardly positioned sliding support 950 is far from the center of gravity of the main body 200, the recycling and storage section 400, the gas-liquid separator 500, the suction device 600, and the rechargeable battery 800 of the surface cleaning device, the force exerted on the main body 200 is smaller. Correspondingly, the friction during its left-right movement on the surface to be cleaned is also smaller, thereby facilitating the user's left-right movement of the surface cleaning device.

[0197] In a preferred embodiment, the main body 200 can be laid flat relative to the cleaning base 100 in a first direction, which is the rearward direction of the surface cleaning device, meaning that the main body 200 of the surface cleaning device can be laid back. More preferably, in the flat state, the main body 200 forms a first angle with the flat surface to be cleaned, the first angle being 0-5°.

[0198] Therefore, the recycling and storage section 400 of this disclosure is located on the rear side of the main body 200 and forms at least a portion of the outer surface of the surface cleaning device; when the sliding support section 950 contacts the flat surface to be cleaned, the recycling and storage section 400 does not contact the flat surface to be cleaned, thereby enabling the surface cleaning device of this disclosure to be supported only by the cleaning base 100 and the sliding support section 950, which facilitates the movement of the surface cleaning device on the surface to be cleaned.

[0199] In a preferred embodiment, the sliding support 950 includes at least one of a parallel roller, a swivel wheel, and a bidirectional wheel.

[0200] Figure 23 This is a schematic diagram of the structure of a suction device 600 according to one embodiment of the present disclosure. Figure 24 This is a cross-sectional structural schematic diagram of a suction device 600 according to one embodiment of the present disclosure. Figure 25 yes Figure 24 A magnified structural diagram of part D. Figure 26 This is a schematic diagram of the structure of an impeller 640 according to one embodiment of the present disclosure.Figure 27 This is a structural schematic diagram of the impeller 640 from another angle according to one embodiment of the present disclosure.

[0201] like Figure 23 to Figure 27 As shown, the suction device 600 of this disclosure may include a frame 610 and a cover 620.

[0202] One end (lower end) of the cover 620 is open, and the other end (upper end) of the cover 620 forms an air inlet for the suction device 600; at least a portion of the upper end of the frame 610 is located within the opening of the cover 620, and an exhaust port for the suction device is formed between the outer peripheral surface of the frame 610 and the inner peripheral surface of the cover 620.

[0203] For details regarding the specific structure of the frame 610 and the cover 620, please refer to the content disclosed in Chinese Utility Model Patent Publication CN216907776U. This publication will not elaborate on these details further.

[0204] The suction device 600 disclosed herein includes a motor 630 and an impeller 640. The motor 630 may include a stator assembly 631 and a rotor assembly 632. The stator assembly 631 may be fixed inside the frame 610 by fastening elements such as screws, and the rotor assembly 632 may be rotatably disposed on the frame 610.

[0205] Specifically, with Figure 23 As shown, the frame 610 includes a top wall, and the rotor assembly 632 is rotatably mounted on the top wall of the frame 610 via bearings. Therefore, during the rotation of the rotor assembly 632, some gas may enter the interior of the frame 610 through the gap between the rotor and the top wall of the frame 610, affecting the normal operation of the motor 630. The suction device disclosed herein is a structure designed to solve this technical problem.

[0206] In this disclosure, at least a portion of the rotor assembly 632 passes through the top wall and is located outside the frame 610; that is, with Figure 23 In the indicated direction, at least a portion (shaft) of the rotor assembly 632 is located above the frame 610.

[0207] Impeller 640 is disposed on rotor assembly 632 and driven and rotated by rotor assembly 632; in this disclosure, impeller 640 includes turntable 641, a plurality of main blades 642 are disposed on one surface of turntable 641, and at least one secondary blade 643 is disposed on the other surface of turntable 641.

[0208] Therefore, by adding a set of auxiliary blades 643, the suction device 600 of this disclosure can effectively prevent water vapor from entering the motor through the shaft gap and affecting the normal operation of the motor; correspondingly, the service life of the suction device 600 of this disclosure is greatly improved.

[0209] In this disclosure, when the turntable 641 rotates, the main blade 642 is used to generate an airflow from the air inlet to the air outlet, thereby enabling the suction device 600 of this disclosure to generate suction force, that is, to generate negative pressure.

[0210] In one embodiment, the main blade 642 is disposed on the surface of the turntable 641 away from the frame 610, and the secondary blade 643 is disposed on the surface of the turntable 641 close to the frame 610. That is, the secondary blade 643 of this disclosure can be disposed at least partially around the shaft gap, thereby effectively preventing gas from passing through the shaft gap into the motor.

[0211] like Figure 27 As shown, at least one secondary blade 643 extends outward from a position near the center of rotation. Thus, when the turntable 641 rotates, a disturbed airflow is generated through the secondary blade 643. This airflow creates negative pressure on the shaft gap, allowing gas to flow through the shaft gap to the outside of the frame 610, effectively preventing reverse gas flow. In other words, through the arrangement of the secondary blade 643, the airflow generated by its rotation can blow water or water vapor that would normally flow towards the shaft gap away from the shaft gap, thereby achieving waterproofing.

[0212] More preferably, at least one secondary blade 643 has a height extending from the surface of the turntable 641, and the height gradually decreases outward from a position close to the rotation center of the turntable 641. Thus, on the one hand, a turbulent airflow can be effectively formed between the turntable 641 and the frame 610, and on the other hand, the oscillation of the rotating shaft during rotation can be prevented from causing the secondary blade 643 to collide with the frame 610.

[0213] In this disclosure, at least one secondary blade 643 has the same curvature. More preferably, at least one secondary blade 643 has the same curvature as the main blade 642.

[0214] Moreover, at least one secondary blade 643 includes multiple secondary blades 643, which are evenly spaced around the center of the turntable 641 on the outer surface of the turntable 641. As a result, the static and dynamic balance accuracy of the main blade 642 and the secondary blades 643 of this disclosure is high. Correspondingly, the motor of this disclosure can operate at a large speed, for example, the speed of the motor of this disclosure can reach 20,000 rpm.

[0215] In one specific embodiment, at least one secondary blade 643 is six secondary blades 643. Of course, the number of secondary blades 643 in this disclosure can also be set to other values.

[0216] The suction device 600 disclosed herein also includes a diffuser 650, with an impeller 640 adjacent to the diffuser 650 mounted on the frame 610. The diffuser 650 includes a plurality of diffusion blades. Moreover, the diffuser 650 is positioned in the path of the airflow from the inlet to the outlet, so that the gas diffused by the diffuser 650 is discharged outward through the outlet.

[0217] Preferably, a circular groove 651 is formed on the plane of the diffuser 650 facing the impeller 640. More preferably, the circular groove 651 has a bottom surface, and the highest point of at least one auxiliary blade 643 is at a first distance from the bottom surface, the first distance being less than 1 mm; thus, in this disclosure, even if the auxiliary blade of this disclosure is present, the distance between the turntable 641 and the diffuser 650, and the distance between the turntable 641 and the frame 610, can be controlled within a preset range, thereby not increasing the axial dimension of the suction device.

[0218] According to another aspect of this disclosure, a surface cleaning system is provided, which includes the surface cleaning device described above.

[0219] The surface cleaning system disclosed herein may also include a base station, at which the surface cleaning equipment can be docked and charged via the base station.

[0220] The base station can be implemented using existing technical solutions, which will not be elaborated upon here.
