[0111] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0112] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0113] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0114] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0115] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0116] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings.

It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

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

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

[0120] The cleaning base 100 is configured to be suitable for moving 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 It is a schematic structural diagram of a cleaning base according to one embodiment of the present disclosure. Figure 3 2 is a schematic structural diagram of a cleaning base according to an embodiment of the present disclosure from another angle. Figure 4 It is a partial structural schematic diagram of a cleaning base according to one embodiment of the present disclosure. Figure 5 is a schematic structural diagram of a liquid dispensing system 140 according to one embodiment of the present disclosure.

[0122] like Figures 2 to 5 As shown, the cleaning base 100 of the present disclosure may include a longitudinal direction and a transverse direction. Taking the cleaning base 100 moving on a substantially horizontal surface to be cleaned and cleaning the surface to be cleaned 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 or substantially perpendicular to the longitudinal direction. In other words, the longitudinal direction and the transverse direction of the present disclosure may both be horizontal directions.

[0123] The cleaning base 100 may include a seat component 110, and a travel mechanism 120 may be installed on the seat component 110, so that the cleaning base 100 can be moved on the surface to be cleaned through the travel mechanism 120. The travel mechanism 120 may include two rollers, which may be arranged at the rear of the seat component 110 in the longitudinal direction and respectively arranged at two ends in the transverse direction, thereby supporting the seat component 110 through the two rollers. 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 component 110 when cleaning the surface to be cleaned, correspondingly, the support of the seat component 110 can be achieved through the cleaning member 170 and the two rollers.

[0124] In another embodiment, the walking mechanism 120 may include four rollers, which are respectively located at the four corners of the seat component 110 close to the surface to be cleaned. Accordingly, the four rollers can achieve stable support for the seat component 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] A cleaning liquid storage portion 130 is also provided on the seat part 110. That is, different from the prior art, the cleaning liquid storage portion 130 of the present disclosure is a part of the cleaning base 100. Water or cleaning liquid is stored in the cleaning liquid storage portion 130, and the water or cleaning liquid stored in the cleaning liquid storage portion 130 can be provided to the cleaning member 170 through the liquid distribution system 140. Moreover, since the surface cleaning device of the present disclosure includes the cleaning liquid storage portion 130, it can perform wet cleaning on the surface to be cleaned, and accordingly, it can also be called a wet surface cleaning device.

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

[0127] Preferably, the cleaning liquid storage part 130 of the present disclosure can be removed from the seat part 110 by pulling it backward. That is, when the amount of cleaning liquid in the cleaning liquid storage part 130 is small, the cleaning liquid storage part 130 can be taken out by pulling it backward, and after adding water or cleaning liquid to the cleaning liquid storage part 130 again, the cleaning liquid storage part 130 can be installed on the seat part 110 by pushing it forward.

[0128] The cleaning base 100 of the present disclosure may further include a cover 150; the cover 150 is disposed on the seat 110 and is located at the front of the seat 110 in the longitudinal direction. The front end of the cover 150 and the seat 110 together form a receiving space, and a cleaning member 170 may be disposed in the receiving space. In a preferred embodiment, the cover 150 can be detached from the seat 110, and thus the cover 150 can be conveniently cleaned, and accordingly the cleaning base 100 can also be conveniently cleaned.

[0129] The cover body 150 has a first circumferential end and a second end, wherein the first circumferential end of the cover body 150 is formed as a free end, and the second circumferential end of the cover body 150 is arranged close to the upper surface of the seat component 110 and has a preset interval with the upper surface of the seat component 110.

[0130] A suction port 190 is formed on the seat part 110, and the suction port 190 is located behind the cleaning member 170. In addition, a cleaning member 160 is provided above the seat part 110, and at least a portion of the cleaning member 160 extends out from the preset interval and can contact the fluff of the cleaning member 170 to scrape off the dirt attached to the cleaning member 170; and after the dirt is scraped off by the cleaning member 160, it will enter the recovery storage part 400 through the suction port 190 under the action of gravity and the negative pressure adsorption of the suction port 190.

[0131] The cleaning member 170 is detachably disposed on the seat member 110, and at least a portion of the cleaning member 170 is located in the accommodation space. The cleaning member 170 of the present disclosure can rotate, and cleans the surface to be cleaned by frictional contact with the surface to be cleaned during the rotation process.

[0132] The cleaning member 170 of the present disclosure may be implemented by using structures in the prior art, which will not be described in detail in the present disclosure.

[0133] In the present disclosure, the liquid dispensing system 140 may include a water pump 141 and a dispensing component 142, wherein the water pump 141 is used to extract the cleaning liquid in the cleaning liquid storage part 130 and provide the cleaning liquid to the dispensing component 142 after pressurization. The dispensing component 142 is disposed on the seat part 110 and is located behind the cover part 150. The lower end of the dispensing component 142 is located above the cleaning component 160, and at least part of the liquid provided by the dispensing component 142 can be discharged to the cleaning component 160 and provided to the cleaning member 170 via the cleaning component 160.

[0134] Figure 6 2 is a schematic structural diagram of a partial structure of a cleaning base according to an embodiment of the present disclosure from another angle. Figure 7 yes Figure 6 A magnified schematic diagram of part A. Figure 8 It is a schematic structural diagram of a distribution component (part) according to one embodiment of the present disclosure. Fig. 9 yes Figure 8 An enlarged schematic diagram of part B. Fig.10 It is a schematic structural diagram of a distribution component according to an embodiment of the present disclosure from another angle.

[0135] Specifically, the dispensing component 142 includes a base portion 142A, and the base portion 142A has a front surface and a rear surface, wherein a liquid dispensing channel 142C is formed on the rear surface of the base portion 142A, and the liquid pressurized by the water pump 141 can be provided to the liquid dispensing channel 142C and distributed by the liquid dispensing channel 142C. In a preferred embodiment, the liquid dispensing channel 142C has a plurality of ends, and a drainage hole 142D is formed at the end of the liquid dispensing channel 142C. Accordingly, the drainage hole 142D is provided in plurality and is provided through the base portion 142A, so that the cleaning liquid can flow to the front surface of the base portion 142A through the drainage hole 142D.

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

[0137] In a specific embodiment, part of the rib structure 142B in the rib structure 142B is arranged corresponding to the drainage hole 142D, and at least part of the rib structure 142B arranged corresponding to the drainage hole 142D is spaced apart from the front surface of the base portion 142A, so that the drainage hole 142D can be connected to the liquid distribution space on both sides of the rib structure 142B, so that the cleaning liquid can be discharged to the liquid distribution space through the drainage hole 142D.

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

[0139] The rib structure 142B is provided with a guide structure 142E, and the guide structure 142E is configured so that the liquid discharged from the drainage hole 142D is guided by the guide structure 142E to the middle area of ​​the liquid distribution space in the transverse direction.

[0140] Moreover, the liquid distribution space includes a rear side wall 142F, which forms a part of the front surface of the base portion 142A. The rear side wall 142F is inclined forward in the lateral direction along the direction away from the guide structure 142E, so that the liquid entering the liquid distribution space can be discharged to the front part of the liquid distribution space as quickly as possible and 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 transverse direction, so that the bottom wall 142G includes a low area, which is roughly located in the middle of the liquid distribution space in the transverse direction to form a liquid flow path through the low area.

[0142] Moreover, the bottom wall 142G is inclined downward in the direction from the back to the front, so that the cleaning liquid can flow forward on the bottom wall 142G under the action of gravity and flow to the cleaning component 160. At this time, at least a portion of the cleaning component 160 (for example, a portion located below the dispensing component 142) is arranged to be inclined downward in the direction from the back to the front, so that the cleaning liquid can be provided to the cleaning member 170 through the cleaning component 160 under the action of gravity.

[0143] In the present disclosure, through the redesigned liquid distribution system, the cleaning liquid can be distributed more evenly on the cleaning element, effectively avoiding the uneven dry and wet phenomenon on the cleaning element 170, and improving the cleaning effect of the surface cleaning device of the present disclosure.

[0144] Fig.11 Schematic diagram of a partial structure of a surface cleaning device according to an embodiment of the present disclosure. Fig.12 It is a schematic structural diagram of a recovery storage unit and a suction device according to an embodiment of the present disclosure. Fig.13 It is a schematic structural diagram of the recovery storage part and the suction device from another angle according to an embodiment of the present disclosure.

[0145] like Figure 1 and Figures 11 to 13 As shown, the cleaning base 100 of the present disclosure is operably connected to the main body 200. Specifically, in the present disclosure, the cleaning base 100 also includes a support 180, which can be fixed to the seat component 110; the support 180 is rotatably provided with a connecting portion 300. In one embodiment, the connecting portion 300 can rotate relative to the support 180, and the rotation axis of the connecting portion 300 relative to the support 180 is a straight line extending in the transverse direction. At the same time, there is also a preset height between the rotation axis and the surface to be cleaned.

[0146] The lower end of the main body 200 is fixed to the connecting part 300, so that the main body 200 rotates relative to the cleaning base 100. Accordingly, on the one hand, the main body 200 can be supported on the cleaning base 100 in a self-supporting state, in which case the cleaning base 100 is arranged approximately horizontally, and the main body 200 is arranged approximately vertically, or the main body 200 is in a forward tilted posture, that is, in the projection of the main body 200 on 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 flat posture (lying posture / lying state), wherein the flat posture means that the axis of the main body 200 is arranged parallel to the horizontal plane, or the angle between the axis of the main body 200 and the horizontal plane is about 0-5°, so that at least part of the rear surface of the main body 200 can be close to the surface to be cleaned.

[0147] The main body 200 of the present disclosure has a height direction. Specifically, when the main body 200 is in an upright state and is arranged substantially vertically, the vertical direction is the height direction (axial direction) of the main body 200. The following height direction is the height direction of the main body 200 unless otherwise specified.

[0148] In a 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 .

In a preferred embodiment, the upper surface of the recovery storage part 400 forms a part of the upper surface of the surface cleaning device. The side surface of the recovery storage part 400 forms a part of the side surface of the surface cleaning device, and the rear surface of the recovery storage part 400 forms a part of the rear surface of the surface cleaning device.

[0150] In particular, when the recovery storage part 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, and the recovery storage part 400 includes a second upper surface. When the recovery storage part 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.

Fig.15 It is a schematic structural diagram of a solid-liquid separation device according to an embodiment of the present disclosure. Fig.16 It is a schematic structural diagram of a solid-liquid separation device according to an embodiment of the present disclosure from another angle.

[0152] like Figures 14 to 16 As shown, in a specific embodiment, the recovery storage part 400 includes a box body 410 and a solid-liquid separation device 420; wherein, a sewage pipe 411 is arranged in the box body 410, and a through hole is opened on the bottom wall of the box body 410, and the liquid 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 pipeline, so that when negative pressure is applied to the recovery storage part 400, a mixture of dirt and cleaning liquid can be sucked into the recovery storage part 400 through the pipeline and the sewage pipe 411, and stored in the recovery storage part 400.

[0153] The upper end of the box body 410 of the present invention is open, and the solid-liquid separation device 420 is arranged in the box body 410, and at least part of the solid-liquid separation device 420 is located inside the box body 410, and at least part of it is located outside the box body 410. Accordingly, the upper surface of the solid-liquid separation device 420 forms a part of the upper surface of the surface cleaning equipment.

[0154] Fig.15 It is a schematic structural diagram of a solid-liquid separation device according to an embodiment of the present disclosure. Fig.16 It is a schematic structural diagram of a solid-liquid separation device according to an embodiment of the present disclosure from another angle.

[0155] like Fig.15 and Fig.16 As shown, the solid-liquid separation device 420 of the present disclosure includes an upper component 421, and a sealing portion is arranged around the periphery of the upper component 421. When the solid-liquid separation device 420 is installed on the box body 410, the upper opening of the box body 410 is sealed by the cooperation between the sealing portion and the inner circumferential surface of the box body 410.

[0156] Moreover, the solid-liquid separation device 420 further includes a lower member 422, which is spaced apart from the upper member 421 and connected via a connecting plate 423. A filter structure 424 is provided on the lower surface of the lower member 422, wherein a sealing ring is provided around a portion of the lower member 422 and around the filter structure 424, thereby a sealed space can be enclosed by the lower member 422, the filter structure 424 and the inner wall of the box body 410, and when solid dirt and clean liquid are transported to the sealed space through the sewage pipe, the clean liquid therein can be filtered by the filter structure 424, and the solid dirt can be stored in the sealed space, thereby achieving solid-liquid separation of dirt.

[0157] Fig.17 is a schematic structural diagram of a first latch and a second latch according to an embodiment of the present disclosure. Fig.18 is a schematic structural diagram of a first operating unit according to an embodiment of the present disclosure. Fig.19 is a schematic structural diagram of an actuating component according to an embodiment of the present disclosure.

[0158] The solid-liquid separation device 420 of the present disclosure further includes a first latch 425, which is used to lock the solid-liquid separation device 420 at the opening of the box body 410; wherein the first latch 425 has a first operable stroke to unlock the solid-liquid separation device 420 from the box body 410; specifically, the first latch 425 of the present disclosure includes a first operating portion 425A, which can be formed in the form of a button. In the present disclosure, when downward pressure is applied to the first operating portion 425A, the first operating portion 425A moves downward, and the two claws 425B of the first latch 425 are retracted, thereby enabling the solid-liquid separation device 420 to be unlocked from the box body 410.

[0159] In the opposite process, a bayonet is formed on the inner wall of the box body 410. When the first operating part 425A is not operated, under the action of the restoring force of the spring, the first operating part 425A will move upward, or be maintained at the maximum upward displacement, so that the two claws 425B of the first latch 425 extend out and are at least partially located in the bayonet of the box body 410, thereby locking the solid-liquid separation device 420 to the box body 410.

[0160] The solid-liquid separation device 420 of the present disclosure further includes a housing portion 427, which is disposed on the upper member 421, and allows at least a portion of the first latch 425 to be located inside the housing portion 427; in the present disclosure, the upper surface of the housing portion 427 forms a portion of the upper surface of the surface cleaning device, and a through hole is provided on the upper surface of the housing portion 427, and at least a portion of the first operating portion 425A is located inside the through hole of the housing portion 427, so as to facilitate the user to operate the first operating portion 425A. In a preferred embodiment, when the first operating portion 425A is at the maximum position in the upward direction, the upper surface of the first operating portion 425A can be flush or substantially flush with the upper surface of the housing portion 427.

[0161] In the present disclosure, the first latch 425 has a first operable stroke; wherein the first operable stroke of the first latch 425 may be a downward movement stroke of the first operating portion 425A.

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

[0163] In addition, the surface cleaning device of the present disclosure may further include a second latch 700, which can be provided on the main body 200. Moreover, the second latch 700 has a second operable stroke to unlock the recovery storage unit 400 from the main body 200; when the recovery 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 portion 710 and a locking hook 720, wherein the second operating portion 710 is configured to be able to move up and down relative to the main body 200. In a preferred embodiment, the second operating portion 710 and the locking hook 720 can be formed integrally, and when the second operating portion 710 is applied with a downward external force and moves downward, the second operating portion 710 and the locking hook 720 move downward together, thereby releasing the recovery storage portion 400.

[0165] Specifically, when the second operating portion 710 is at the maximum position in the upward direction, the lock hook 720 can pass through the housing portion 427 and be at least partially located in the housing portion 427, and the lock hook 720 can cooperate with the side wall of the housing portion 427 to lock the recovery storage portion 400 on the main body 200. When the second operating portion 710 is at the maximum position in the downward direction, the lock hook 720 can be disengaged from the side wall of the housing portion 427, thereby unlocking the recovery storage portion 400 from the main body 200.

[0166] A through hole is provided on the upper surface of the main body 200 of the present disclosure, and at least a portion of the second operating portion 710 is located in the through hole of the main body 200, so as to facilitate the user to operate the second operating portion 710. In a preferred embodiment, when the second operating portion 710 is at the maximum position in the upward direction, the upper surface of the second operating portion 710 can be flush or substantially flush with the upper surface of the main body 200 (i.e., the first upper surface).

[0167] The second operable stroke may be a downward movement stroke of the second operating portion 710. Accordingly, 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 is not started.

[0168] Based on the above structure, in the present disclosure, when the second operating portion 710 is at the maximum position in the upward direction and the recovery storage portion 400 is installed on the main body 200, the actuating member 426 can be blocked by the second latch 700 so that the first operable stroke is limited. Specifically, the actuating member 426 can be limited by the lock hook 720, so that when the user presses the first operating portion 425A downward, the lock hook 720 does not allow the actuating member 426 to move to the left (outward), so that the first operating portion 425A cannot move downward to the position of opening the first latch 425. At this time, the first latch 425 cannot be opened, and further makes it impossible for the solid-liquid separation device 420 to be disassembled from the box body 410.

[0169] In another case, when the recovery storage part 400 is not installed on the main body 200, the movement of the actuating member 426 will not be restricted. At this time, when the first operating part 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, so that the solid-liquid separation device 420 and the box body 410 can be separated.

[0170] In a specific embodiment, the actuating member 426 includes a push rod having a free end and an operating end opposite to the free end; the operating end is operably connected to the first operating portion 425A of the first latch 425. More specifically, the first operating portion 425A includes an actuating slot, and at least a portion of the operating end of the push rod is located in the actuating slot, so that when the first operating portion 425A is operated, an actuating force is provided to the operating end of the push rod, thereby enabling the actuating member 426 to move leftward (outward) when the first operating portion 425A moves downward.

[0171] In the present disclosure, the operating end of the push rod includes a first actuating surface 426A, and a second actuating surface 425A1 is 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 to drive the push rod to move; wherein, the first actuating surface 426A and the second actuating surface 425A1 are both inclined surfaces.

[0172] Accordingly, when the recovery storage portion 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 lock hook 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 the present disclosure, the cooperation between 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] Refer to Fig.11 and Fig.19 The surface cleaning device of the present invention also includes a rechargeable battery 800, which is used to provide operating power for the surface cleaning device. Specifically, the rechargeable battery 800 can provide electrical energy for the cleaning base 100 (such as 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] Moreover, the suction device 600 of the present invention can be fixed to the main body 200 and used to provide vacuum suction (negative pressure) from the cleaning base 100 to the recovery storage part 400. That is to say, after the suction device 600 of the present invention applies negative pressure to the recovery storage part 400, the negative pressure can be provided to the suction port 190 of the cleaning base 100, and the dirt and recovered liquid can enter the recovery storage part 400 through the suction port 190 and the pipeline under the action of the negative pressure and be stored in the box part 410 of the recovery storage part 400.

[0176] The gas-liquid separator 500 of the present disclosure can be fixed to the main body 200, and at least partially disposed inside the recovery storage part 400. That is, when the recovery storage part 400 is located on the main body 200, at least part of the gas-liquid separator 500 is located inside the recovery storage part 400, so that the liquid passing through the gas-liquid separator 500 can be filtered by the gas-liquid separator 500, and the gas between the gas-liquid separator 500 and the suction device 600 can be kept as dry as possible, or the gas entering the suction device 600 can be kept as dry as possible.

[0177] That is, in terms of the flow direction of the gas, the gas-liquid separator 500 may be located upstream of the suction device 600, that is, the gas flowing out of the recovery storage unit 400 first passes through the gas-liquid separator 500 for gas-liquid separation, then enters the air inlet of the suction device 600, and then is discharged from the exhaust port of the suction device 600. At this time, the air inlet of the suction device 600 is used to connect to the exhaust port of the gas-liquid separator 500.

[0178] In the present disclosure, the positions of the suction device 600 and the rechargeable battery 800 on the main body 200 are closer to the cleaning base 100 than the gas-liquid separator 500. Therefore, compared with the prior art, the center of gravity of the surface cleaning device of the present disclosure is lower, and when the user operates the surface cleaning device, it has the technical effect of being easy to operate and more labor-saving.

[0179] In addition, the surface cleaning device of the present disclosure can be in a lying state when in use, and in this lying state, operation is more labor-saving.

[0180] In a preferred embodiment, the rechargeable battery 800 is closer to the cleaning base 100 than the suction device 600. This design mainly takes into account that surface cleaning equipment generally requires a longer battery life, and the corresponding rechargeable battery 800 is heavier. Therefore, placing the rechargeable battery 800 in a lower position will make the center of gravity of the surface cleaning equipment of the present disclosure lower.

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

[0182] In a preferred embodiment, the recovery storage section 400 and the suction device 600 are arranged relative to each other in the front-to-back direction of the main body 200; relatively speaking, the recovery storage section 400 is located on the rear side of the main body 200, and the suction device 600 is located on the front side of the main body 200, so that the surface cleaning device of the present disclosure can minimize the liquid disturbance in the recovery storage section 400 when lying down; at this time, when the main body 200 is supported on the surface to be cleaned in a flat state, one surface (the rear surface) of the recovery storage section 400 is set to be 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 section 400.

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

[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, so that the position arrangement of the various components of the surface cleaning equipment of the present invention is more reasonable, thereby reducing the volume of the surface cleaning equipment.

[0185] In some embodiments, at least part 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 part 400 of the present disclosure can have overlapping parts with the gas-liquid separator 500 and the suction device 600 in the height direction, and accordingly, 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 in a flat state on the surface to be cleaned, at least a portion of the sewage pipe 411 is located below the suction device 600; and at least a portion of the sewage pipe 411 is located below the rechargeable battery 800. Thus, the recovery storage part 400 of the present disclosure can have an overlapping portion with the rechargeable battery 800 and the suction device 600 in the height direction, and accordingly, the size of the main body 200 in the height direction can be reduced.

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

[0188] like Fig. 20As shown, the surface cleaning device of the present disclosure further includes an operating handle 900, which is detachably connected to the main body 200 via a connecting rod 910 (the connecting rod 910 is in a straight line, and the connecting rod 910 can also be referred to as an upright connecting rod); and the connecting rod 910 is arranged so that in the height direction of the main body 200, the extension line of the connecting rod 910 passes through the gas-liquid separator 500, the suction device 600 and the rechargeable battery 800 in sequence, and does not pass through the recovery storage part 400. Preferably, the connecting rod 910 is detachably connected to the first upper surface of the main body 200.

[0189] That is, in the present disclosure, the connection 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 accordingly, the recovery storage part 400 is located at the rear of the main body 200, and 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 of the present invention is easier to operate by setting the position of the operating handle 900. Especially when performing cleaning operations, the center of gravity of the surface cleaning device is lower, thereby improving the user experience.

[0191] Furthermore, when the surface cleaning device of the present invention is in a lying state, the connecting rod 910 is located away from the surface to be cleaned, so that the surface cleaning device of the present invention can be laid flat more easily, thereby achieving cleaning operations in a low space.

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

[0193] like Fig.21 and Fig. 22 As shown, the surface cleaning device of the present disclosure may further include a sliding support portion 950. In this case, the operating handle 900 may include a handheld portion, which is configured to be in a shape that is convenient for holding. In other words, the handheld portion is formed as a part of the operating handle 900, and is used to control the posture of the surface cleaning device by holding the handheld portion.

[0194] like Fig. 22 As shown, a sliding support portion 950 is provided on the hand-held portion. When the main body 200 is in a flat state relative to the cleaning base 100, the sliding support portion 950 contacts the flat surface to be cleaned and slidably supports the hand-held portion so that the main body 200 does not contact the flat surface to be cleaned.

[0195] Thus, one end of the main body 200 of the surface cleaning device of the present invention (i.e., the front end in the lying 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 lying state, and the lower end in the upright state) can be supported by the sliding support part 950. Thus, when the main body 200 is in the flat state, the main body 200 and the recovery storage part 400, the gas-liquid separator 500, the suction device 600, the rechargeable battery 800 and other components installed on the main body 200 can all form support with the flat surface to be cleaned.

[0196] By disposing the sliding support part 950 of the surface cleaning device of the present invention backward, the surface cleaning device in a lying state can be supported more stably; moreover, the sliding support part 950 disposed backward is away from the center of gravity of the main body 200, the recovery storage part 400, the gas-liquid separator 500, the suction device 600 and the rechargeable battery 800 of the surface cleaning device as a whole, and the force it applies to the main body 200 is smaller, and accordingly, the friction force during the left and right movement on the surface to be cleaned is also smaller, thereby facilitating the user to move the surface cleaning device left and right.

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

[0198] Therefore, the recovery storage part 400 of the present invention is located on the rear side of the main body 200, forming at least a part of the outer surface of the surface cleaning device; when the sliding support part 950 contacts the flat surface to be cleaned, the recovery storage part 400 does not contact the flat surface to be cleaned, thereby making the surface cleaning device of the present invention supported only by the cleaning base 100 and the sliding support part 950, facilitating the movement of the surface cleaning device on the surface to be cleaned.

[0199] In a preferred embodiment, the sliding support portion 950 includes at least one of parallel rollers, universal wheels, and bidirectional wheels.

[0200] Fig.23 is a schematic structural diagram of a suction device 600 according to an embodiment of the present disclosure. Fig.24 is a schematic cross-sectional structural diagram of a suction device 600 according to an embodiment of the present disclosure. Fig.25 yes Fig.24 Schematic diagram of the enlarged structure of part D. Fig.26 is a schematic structural diagram of an impeller 640 according to an embodiment of the present disclosure. Fig. 27 is a schematic structural diagram of the impeller 640 at another angle according to an embodiment of the present disclosure.

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

[0202] Among them, one end (lower end) of the cover body 620 is open, and the other end (upper end) of the cover body 620 is formed with an air inlet of the suction device 600; at least part of the upper end of the frame 610 is located in the opening of the cover body 620, and an exhaust port of the suction device is formed between the outer peripheral surface of the frame 610 and the inner peripheral surface of the cover body 620.

[0203] Regarding the specific structure of the frame 610 and the cover body 620, reference may be made to the contents disclosed in the Chinese utility model patent publication document CN216907776U, which will not be described in detail in this disclosure.

[0204] The suction device 600 of the present disclosure includes a motor 630 and an impeller 640 , wherein 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, Fig.23 In the direction shown, the frame 610 includes a top wall, and the rotor assembly 632 is rotatably disposed on the top wall of the frame 610 through a bearing. 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, and affect the normal operation of the motor 630. The suction device disclosed in the present invention is a structure designed to solve this technical problem.

[0206] In the present disclosure, at least a portion of the rotor assembly 632 passes through the top wall and is located outside the frame 610; Fig.23 In the orientation shown, at least a portion (rotation axis) of the rotor assembly 632 is located above the frame 610 .

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

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

[0209] In the present disclosure, when the turntable 641 rotates, the main blades 642 are used to generate an air flow from the air inlet to the air outlet, so that the suction device 600 of the present disclosure can generate a suction force, that is, can generate negative pressure.

[0210] In one embodiment, the main blades 642 are arranged on the surface of the turntable 641 away from the frame 610, and the auxiliary blades 643 are arranged on the surface of the turntable 641 close to the frame 610. That is to say, the auxiliary blades 643 of the present invention can be arranged at least partially around the shaft gap, thereby effectively preventing gas from passing through the shaft gap into the interior of the motor.

[0211] like Fig. 27 As shown, at least one auxiliary blade 643 extends outward from a position close to the rotation center; therefore, when the turntable 641 rotates, a disturbed air flow can be formed through the auxiliary blade 643, and the air flow can form a negative pressure on the shaft gap, and the gas can flow to the outside of the frame 610 through the shaft gap, effectively avoiding the reverse flow of the gas. In other words, through the setting of the auxiliary blade 643, the airflow generated by its rotation can blow the water or water vapor originally flowing to the shaft gap to a position away from the shaft gap, thereby achieving the purpose of waterproofing.

[0212] More preferably, at least one auxiliary blade 643 has a height extending from the surface of the turntable 641, and the height gradually decreases from a position close to the rotation center of the turntable 641 to the outside. Therefore, on the one hand, a disturbed air flow can be effectively formed between the turntable 641 and the frame 610. On the other hand, it can also avoid the swing of the shaft during rotation, causing the auxiliary blade 643 to collide with the frame 610.

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

[0214] Moreover, at least one auxiliary blade 643 includes multiple auxiliary blades 643, and the multiple auxiliary blades 643 are evenly spaced around the center of the turntable 641 on the outer surface of the turntable 641; thus, the static balance and dynamic balance accuracy of the main blade 642 and the auxiliary blade 643 disclosed in the present invention are relatively high, and accordingly, the motor disclosed in the present invention can operate at a higher speed, for example, the speed of the motor disclosed in the present invention can reach 20000rps.

[0215] In a specific embodiment, the at least one auxiliary blade 643 is six auxiliary blades 643. Of course, the number of the auxiliary blades 643 of the present disclosure may also be set to other values.

[0216] The suction device 600 of the present disclosure further includes a diffuser 650. The impeller 640 is adjacent to the diffuser 650 installed on the frame 610. The diffuser 650 includes a plurality of diffusion blades. Moreover, the diffuser 650 is arranged in the path of the air flow from the air inlet to the exhaust port, so that the gas diffused by the diffuser 650 is discharged outward through the exhaust port.

[0217] Preferably, a circular groove 651 is formed on the plane of the diffuser 650 facing the impeller 640.
