[0040] This utility model has at least the following beneficial effects:

[0041] The surface cleaning device provided in this application includes a base assembly and a dirt collection assembly. During the cleaning process of cleaning dirt on the surface to be cleaned, the generated dirt can be transported into the dirt collection assembly. In other words, the dirt collection assembly is used to store dirt, such as solid dirt and dirty water. Because the dirt collection assembly is located on the base assembly, the distance between the dirt collection assembly and the base assembly is very short, resulting in a short dirt transport path. On the one hand, this eliminates the need for long pipes, simplifying the structure; on the other hand, it greatly reduces the probability of dirt accumulation in areas other than the dirt collection assembly, reducing odor generation and making the cleaning device more hygienic to use; thirdly, it facilitates user cleaning of the dirt collection assembly, making the maintenance of the cleaning device more convenient; fourthly, regarding the counterweight of the cleaning device, when using a handheld cleaning device for cleaning operations, placing the dirt collection assembly on the base assembly allows the dirt collection assembly to be relatively far from the user's hand position, bringing the center of gravity of the cleaning device closer to the base assembly, increasing the grip of the cleaning device, improving cleaning ability, and facilitating user movement of the cleaning device, making its use more effortless. The waste collection component is detachably connected to the base component. Based on this, when a large amount of dirt accumulates in the waste collection component, such as a large amount of solid dirt and / or sewage, the user can remove the waste collection component via the base component to empty the sewage and solid dirt inside. Afterwards, the waste collection component can be rinsed with clean water, and finally, the waste collection component can be reassembled into the base component. This design facilitates the maintenance of the cleaning equipment, further suppresses the generation of odors, and improves the user experience.

[0065] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0066] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0067] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0068] like Figures 1 to 14As shown, a surface cleaning device is provided according to a first aspect of the embodiments of this application, comprising: a base assembly 110; and a dirt collection assembly 120 including a first disassembly structure 121 and a housing 122, the housing 122 being disposed on the base assembly 110 for storing dirt collected from the surface to be cleaned. The first disassembly structure 121 is disposed on the housing 122 for locking the housing 122 to the base assembly 110 or unlocking the housing 122 from the base assembly 110.

[0069] The surface cleaning device provided in this application includes a base assembly 110 and a dirt collection assembly 120, based on which dirt generated during operation can be transported into the dirt collection assembly 120. In other words, the dirt collection component 120 is used to store dirt, such as solid dirt and dirty water. Since the dirt collection component 120 is set on the base component 110, the distance between the dirt collection component 120 and the base component 110 is very short, resulting in a short dirt transport path. On the one hand, there is no need to set up a long pipe, simplifying the structure; on the other hand, it greatly reduces the probability of dirt accumulation in areas other than the dirt collection component 120 on the surface cleaning device, reducing odor generation and making the use of the surface cleaning device more hygienic; thirdly, it makes it easier for users to clean the dirt collection component 120, making the maintenance of the surface cleaning device more convenient; fourthly, regarding the counterweight of the surface cleaning device, when using the handheld surface cleaning device to perform cleaning operations, setting the dirt collection component 120 on the base component 110 allows the dirt collection component 120 to be relatively far from the user's hand position, making the center of gravity of the surface cleaning device closer to the base component 110, increasing the grip of the surface cleaning device, improving cleaning ability, and making it easier for users to move the surface cleaning device, making the use of the surface cleaning device more effortless.

[0070] It is understood that the base assembly 110 is the main body used to perform cleaning operations. That is, during use, the base assembly 110 is used to contact the ground. The specific design of the base assembly 110 is not limited in this application; for example, the base assembly 110 may include a rotating roller brush, a reciprocating plate-shaped cleaning component 210, a rotating cleaning disc, etc. These specific embodiments capable of achieving cleaning are all within the protection scope of this application. Compared to the conventional technology that arranges the wastewater tank inside the body 220, this application arranges the waste collection assembly 120 directly on the base assembly 110, greatly shortening the waste path, facilitating dirt collection, inhibiting the generation of bacteria and odors, simplifying the maintenance of the surface cleaning device, and improving the user experience.

[0071] The surface cleaning device provided in this application embodiment further provides a connection method for the dirt collection component 120. The dirt collection component 120 is disposed on the base component 110 and is detachably connected to the base component 110. Based on this, when a large amount of dirt accumulates in the dirt collection component 120, such as a large amount of solid dirt and / or sewage, the user can disassemble the dirt collection component 120 via the base component 110 to pour out the sewage and solid dirt inside the dirt collection component 120. Afterwards, the dirt collection component 120 can be rinsed with clean water. Finally, the dirt collection component 120 can be reassembled into the base component 110. This arrangement facilitates the maintenance of the surface cleaning device, can further suppress the generation of odors, and improve the user experience.

[0072] The surface cleaning device provided in this application embodiment further provides the structural composition of the dirt collection component 120. The dirt collection component 120 may include a first disassembly structure 121 and a housing 122. The housing 122 is a carrier for holding dirty water and dirt. The housing 122 can be detachably connected to the base assembly 110 through the first disassembly structure 121. This arrangement facilitates the maintenance of the surface cleaning device.

[0073] like Figures 1 to 7 As shown, in one feasible embodiment, along the length of the housing 122, the first disassembly structure 121 is arranged on both sides of the housing 122.

[0074] In this technical solution, the location of the first disassembly structure 121 is further provided. There can be two first disassembly structures 121, which are arranged on both sides of the housing 122 along the length of the waste collection component 120. Based on this, when the user moves the waste collection component 120, the user can use the first disassembly structure 121 as a support point to lift or lower the waste collection component 120. The arrangement of the first disassembly structure 121 on both sides of the housing 122 can, on the one hand, make the force on the waste collection component 120 more balanced when it moves, and make it easier to move the waste collection component 120; on the other hand, when the waste collection component 120 is locked on the housing 122, it can increase the locking effect between the waste collection component 120 and the housing 122, and reduce the probability of the waste collection component 120 being unexpectedly loosened.

[0075] like Figures 1 to 6As shown, in one feasible embodiment, the first disassembly structure 121 includes: a handle 1211, which is slidably disposed on the outer wall of the housing 122 and is capable of reciprocating relative to the housing 122; and a sliding part 1212, which is disposed on the outer wall of the housing 122. When the handle 1211 moves relative to the housing 122, it can drive the sliding part 1212 to switch between a first position state and a second position state. When the sliding part 1212 is in the first position state, at least a portion of the sliding part 1212 is inserted into the base assembly 110; when the sliding part 1212 is in the second position state, the sliding part 1212 extends out from the base assembly 110.

[0076] In this technical solution, the first disassembly and assembly structure 121 is further provided. The first disassembly and assembly structure 121 may include a handle 1211 and a sliding part 1212. Based on this, when the sliding part 1212 is inserted into the base assembly 110, the dirt collection assembly 120 can be locked on the base assembly 110. When it is necessary to maintain the dirt collection assembly 120 of the surface cleaning device, the handle 1211 can be used to drive the sliding part 1212 to move, so that the end of the sliding part 1212 is disengaged from the snap-fit ​​position with the base assembly 110. In this case, the dirt collection assembly 120 can be unlocked, and the user can clean the dirt collection assembly 120, making the use of the surface cleaning device more convenient.

[0077] like Figure 1 , Figure 3 , Figure 4 and Figure 11 As shown, in one feasible embodiment, the housing 122 has an open side, and the waste collection assembly further includes: a cover unit 128, which is closably installed on the open side for sealing the housing 122; and a third seal, which is disposed between the cover unit 128 and the housing 122.

[0078] In this technical solution, the structural composition of the surface cleaning device is further provided. The dirt collection component 120 may include a cover unit 128, which is connected to the housing 122 and serves to seal the opening side of the housing 122. A third sealing element may be provided between the cover unit 128 and the housing 122. This arrangement can ensure that the cover unit 128 and the housing 122 have a good sealing effect. The negative pressure generated by the negative pressure component can better act on the sewage discharge, which can ensure the surface cleaning device's effect on collecting dirt.

[0079] like Figure 1 , Figure 3 , Figure 4 and Figure 11As shown, in one feasible embodiment, the surface cleaning device further includes a second disassembly structure 129, which is used to lock the cover unit 128 onto the housing 122 or to unlock it from the housing 122.

[0080] In this technical solution, the surface cleaning device may further include a second disassembly structure 129. The second disassembly structure 129 is used to lock the cover unit 128 onto the housing 122 or unlock the housing 122. Based on this, during operation, the cover unit 128 can be locked onto the housing 122 via the second disassembly structure 129, keeping the housing 122 sealed. When the user maintains the surface cleaning device, the user can unlock the cover unit 128 via the second disassembly structure 129, allowing the cover unit 128 to detach from the housing 122. In this case, the plate 1231 inside the housing 122 can be exposed, allowing the user to directly pour out solid waste collected on the plate 1231. This also facilitates rinsing the plate 1231 and emptying the wastewater in the wastewater containing space 1222. This design makes the maintenance of the surface cleaning device more convenient.

[0081] like Figure 5 , Figure 11 and Figure 12 As shown, in one feasible embodiment, the second disassembly structure 129 includes: a snap plate 1291, which is hinged to the cover unit 128; a snap position 1292, which is disposed on the housing 122, and the snap plate 1291 is used to snap onto the snap position 1292; a slot 1293, which is formed on the housing 122 and located on the side of the housing 122 opposite to the snap position 1292; and a connector 1294, which is disposed on the cover unit 128 and located on the side of the cover unit 128 opposite to the snap plate 1291, and the connector 1294 is used to insert into the slot 1293.

[0082] In this technical solution, the second disassembly and assembly structure 129 is further provided. The second disassembly and assembly structure 129 may include a buckle plate 1291, a buckle position 1292, a slot 1293, and a plug-in component 1294. Based on this, during the locking process of the cover unit 128, the user can first insert the plug of the cover unit 128 into the slot 1293, then fasten the cover unit 128 onto the housing 122, and finally fasten the buckle plate 1291 onto the buckle position 1292. Based on this, the locking of the cover unit 128 can be completed.

[0083] In this technical solution, during the unlocking process of the cover unit 128, the buckle plate 1291 can be rotated first to move the buckle plate 1291 away from the buckle position 1292, and then the cover unit 128 can be disassembled by detaching it from the box body 122.

[0084] In one feasible implementation, the waste collection assembly 120 includes: a first disassembly structure 121 and a housing 122. The first disassembly structure 121 is disposed on the housing 122 and is used to lock the housing 122 to the base assembly 110, to unlock the housing 122 from the base assembly 110, to unlock the cover unit 128, and to lock the cover unit 128 to the housing 122.

[0085] In this technical solution, the first disassembly and assembly structure 121 can be used to unlock and lock the housing 122 and the base assembly 110, and at the same time, the first disassembly and assembly structure 121 can also be used to unlock and lock the cover unit 128. Based on this, the housing 122 and the cover unit 128 can be unlocked simultaneously through one component, which makes the maintenance of the surface cleaning device more convenient.

[0086] In one feasible implementation, the area of ​​the cover unit 128 opposite to the filter element 1232 is transparent. This arrangement allows the user to easily observe the amount of solid dirt inside the filter element 1232 through the cover unit 128, facilitating timely cleaning of solid waste and further reducing the probability of odor generation.

[0087] In one feasible implementation, the first disassembly structure 121 further includes a locking rod, which is disposed on the housing 122 and is used to lock or unlock the cover unit 128.

[0088] In this technical solution, the first disassembly structure 121 may include a locking rod in addition to the handle 1211 and the sliding part 1212. The locking rod is set on the box 122 and is used to lock the cover unit 128. The user can unlock the box 122 by pulling the handle 1211 to move the sliding part 1212. At the same time, the user can unlock the cover unit 128 by pulling the handle 1211 to lift the locking rod.

[0089] It is understood that the locking lever can be connected to the sliding part 1212 or the handle 1211, and based on this, the locking lever can move synchronously with the sliding part 1212 and the handle 1211, so as to... Figure 6 For example, when the handle 1211 moves upward, the locking bar can move upward synchronously with the handle 1211, and the locking bar can lift the cover unit 128 to unlock the cover unit 128. When the handle 1211 moves downward, the locking bar loses its lifting effect on the cover unit 128, and the cover unit 128 can be locked.

[0090] In one feasible implementation, the movement path of the handle 1211 includes a first stroke. When the handle 1211 moves the first stroke, the locking lever and the sliding part 1212 are triggered, causing the housing 122 and the cover unit 128 to unlock or lock synchronously.

[0091] In this technical solution, the movement of the handle 1211 can be a single stroke, which is the first stroke. That is to say, when the handle 1211 is pulled up, the handle 1211 can simultaneously trigger the locking rod and the sliding part 1212, realizing the simultaneous unlocking of the box 122 and the cover unit 128, making the disassembly and maintenance of the waste collection component 120 more convenient.

[0092] In one feasible implementation, the movement path of the handle 1211 includes a second stroke and a third stroke. When the handle 1211 moves to the second stroke, the sliding part 1212 is triggered, causing the housing 122 to unlock or lock. When the handle 1211 continues to move to the third stroke, the locking lever is triggered, causing the cover unit 128 to unlock or lock.

[0093] In this technical solution, the handle 1211 can also have two strokes, namely the second stroke and the third stroke. For example, when the handle 1211 moves in the second stroke, the housing 122 can be unlocked, and when the handle 1211 moves in the third stroke, the cover unit 128 can be unlocked. Based on this, the two components can be unlocked in two steps with one fastener, which is more aesthetically pleasing and can reduce the probability of dirt overflowing when the user moves the dirt collection component 120, making the maintenance of the surface cleaning device more convenient.

[0094] like Figures 1 to 4 As shown, in one feasible embodiment, the waste collection assembly 120 further includes a solid-liquid separation unit 123, which includes: a plate 1231 connected to a housing 122 for dividing the housing 122 into a separation space 1221 and a waste liquid containing space 1222; a filter element 1232 disposed on the plate 1231 and located within the separation space 1221; and a through hole 1233 formed in the plate 1231 to connect the separation space 1221 and the waste liquid containing space 1222.

[0095] This technical solution further provides the structural composition of the dirt collection component 120. The dirt collection component 120 may include a housing 122 and a solid-liquid separation unit 123. The solid-liquid separation unit 123 is disposed inside the housing 122. Based on this, during the operation of the surface cleaning device, the dirt generated during cleaning can first enter the solid-liquid separation unit 123 under negative pressure. Then, the solid dirt and wastewater in the dirt are separated by the solid-liquid separation unit 123. The wastewater enters the housing 122 for storage, while the solid waste can be stored in the solid-liquid separation unit 123. Based on this, solid-liquid separation of dirt can be achieved during the cleaning process.

[0096] In this technical solution, solid waste easily ferments in sewage, producing odors and affecting the environment. Solid-liquid separation allows for timely cleaning of solid waste, reducing odor generation and providing users with a cleaner and more comfortable environment. The solid-liquid separation design also makes the surface cleaning device easier to operate. Users can more easily clean the solid-liquid separation unit 123 and the housing 122, reducing cleaning difficulty and time. It also reduces processing costs: without solid-liquid separation, mixed waste is more difficult and costly to process. Solid-liquid separation allows for more suitable treatment methods for different types of waste, reducing processing costs.

[0097] This technical solution further provides a specific design for the solid-liquid separation unit 123. The solid-liquid separation unit 123 may include a plate 1231, a filter element 1232, and a through hole 1233. Based on this, the plate 1231 can divide the housing 122 into a separation space 1221 and a waste liquid containing space 1222. During the operation of the surface cleaning device, dirt is adsorbed onto the filter element 1232 under negative pressure. Then, under the action of gravity, the liquid flows through the through hole 1233, passes through the filter element 1232, and enters the waste liquid containing space 1222. Solid waste is stored inside the filter element 1232, thereby completing solid-liquid separation.

[0098] In this technical solution, solid-liquid separation is achieved by using a plate 1231, a filter element 1232, and a through hole 1233. This utilizes a mechanical structure combined with the gravity flow of the liquid to achieve solid-liquid separation, resulting in more stable product operation, a lower failure rate, and reduced costs for surface cleaning devices.

[0099] Understandably, during normal operation of the surface cleaning device, the separation space is located at the top of the waste liquid containing space 1222. That is to say, the dirt will first be transported to the separation space 1221 under negative pressure, and then filtered by the filter element 1232. The liquid can then flow into the waste liquid containing space 1222 at the bottom under gravity.

[0100] like Figures 1 to 4 As shown, in one feasible embodiment, the waste collection assembly 120 further includes: an air outlet 126 disposed within the separation space 1221, the air outlet 126 having an air outlet 1261 formed thereon; an isolation member 127 connected to the plate 1231 and disposed between the filter member 1232 and the air outlet 126 to increase the length of the airflow path within the separation space 1221; and a handle 1230 connected to the plate 1231 or the isolation member 127.

[0101] In this technical solution, the structure of the dirt collection component 120 is further provided. The dirt collection component 120 may also include an air outlet 126 and a negative pressure component. Based on this, during the operation of the surface cleaning device, the negative pressure component can generate negative pressure, and under the action of negative pressure, airflow can be generated. The airflow sucks up the dirt generated during the cleaning process of the base component 110. The dirt flows into the filter element 1232 through the suction pipe 125. The filter element 1232 performs solid-liquid separation on the dirt. The solid is retained in the filter element 1232, and the liquid flows into the dirt containing space 1222 by gravity. The airflow is discharged out of the dirt collection component 120 through the air outlet 126. Based on this, a closed loop of air path can be formed. It can be understood that arranging the air outlet 126 in the separation space 1221 results in a smaller amount of liquid in the separation space 1221, which can reduce the probability of liquid being discharged through the air outlet 126 and the probability of liquid entering the negative pressure component, especially reducing the probability of water vapor contaminating the motor of the negative pressure component.

[0102] In this technical solution, considering that airflow always flows towards the place with the lowest pressure, after dirt enters the separation space 1221, liquid may enter the air outlet 126 under the action of airflow. Based on this, an isolation member 127 can be set on the plate 1231. The isolation member 127 blocks the filter 1232 and the air outlet 126. Based on this, it is difficult for the liquid that has just entered the separation space 1221 to be directly adsorbed to the air outlet 126. By setting the isolation member 127, the length of the airflow path in the separation space 1221 is increased. With the longer propagation path, most of the liquid will flow into the dirty liquid receiving space 1222 by gravity through the through hole 1233, which can further reduce the probability of water vapor contaminating the negative pressure component and achieve a better air-water isolation effect.

[0103] In this technical solution, the waste collection component 120 may also include a handle 1230. With the handle 1230, the user can lift the plate 1231, which makes it easier for the plate 1231 to be separated from the box 122, and facilitates the user to maintain and clean the plate 1231. The handle 1230 may be located in the middle area of ​​the plate 1231. When the user lifts the plate 1231 with the handle 1230, the force on the plate 1231 is more balanced, making it easier for the user to move the plate 1231.

[0104] In this technical solution, the handle 1230 is connected to the isolation member 127. Compared with the plate 1231, the handle 1230 can be arranged at a higher height, which can keep the handle 1230 further away from dirt and improve the user experience.

[0105] like Figures 1 to 4As shown, in one feasible embodiment, the plate 1231 is detachably connected to the container 122. This arrangement facilitates the user's removal of the plate 1231 via the container 122, facilitates the user's disposal of solid waste, and facilitates the user's cleaning of the plate 1231.

[0106] like Figures 9 to 10 As shown, in one feasible embodiment, the waste collection assembly 120 further includes a handle 1230 connected to the plate 1231; wherein the handle 1230 is disposed in the middle region of the plate 1231.

[0107] In this technical solution, the waste collection component 120 may also include a handle 1230. With the handle 1230, the user can lift the plate 1231, which makes it easier for the plate 1231 to be separated from the box 122, and facilitates the user to maintain and clean the plate 1231. The handle 1230 is located in the middle area of ​​the plate 1231. When the user lifts the plate 1231 with the handle 1230, the force on the plate 1231 is more balanced, making it easier for the user to move the plate 1231.

[0108] like Figures 9 to 10 As shown, in one possible implementation, the plate 1231 and the spacer 127 are integrally and detachably connected to the housing 122.

[0109] In this technical solution, the relationship between the plate 1231 and the housing 122 is further provided. The plate 1231 and the separator 127 are detachably connected to the housing 122. Based on this, when the user maintains the waste collection assembly 120, the user can lift the handle 1230 to detach the plate 1231 and the separator 127 from the housing 122. The user can then directly pour out the dirt on the plate 1231, making the maintenance of the waste collection assembly 120 more convenient.

[0110] like Figure 1 , Figures 9 to 10 As shown, in one possible implementation, the plate 1231, the spacer 127 and the cover unit 128 are integrally and detachably connected to the housing 122.

[0111] In this technical solution, the plate 1231, the isolator 127, and the cover unit 128 are detachably connected to the housing 122. Based on this, when the user maintains the waste collection assembly 120, the user can lift the cover unit 128 to detach the plate 1231, the isolator 127, and the cover unit 128 from the housing 122. Then, the user can open the cover unit 128 to clean and maintain the plate 1231 and the isolator 127. In this case, the handle 1230 does not need to be provided on the plate 1231 or the isolator 127, which can further reduce the probability of the user coming into contact with dirt when maintaining the waste collection assembly 120.

[0112] like Figure 8 As shown, in one feasible embodiment, the waste collection assembly 120 further includes: a pouring port 1220, which is formed in the housing 122 and leads to the waste liquid containing space 1222. At least a portion of the pouring port 1220 is higher than the plate 1231.

[0113] In this technical solution, in order to facilitate the dumping of sewage in the tank 122, a dumping port 1220 can also be provided on the tank 122. Users can directly dump the sewage in the sewage holding space 1222 of the tank 122 through the dumping port 1220, making the surface cleaning device more convenient to use.

[0114] In this technical solution, at least a portion of the pouring port 1220 is higher than the plate 1231. That is, at least a portion of the inner wall of the pouring port 1220 is higher than the plate 1231. Based on this, on the one hand, the pouring port 1220 can be positioned higher, allowing most of the space inside the tank 122 to be used to hold dirty water, thereby increasing the effective volume of the tank 122 and reducing the maintenance frequency of the waste collection component 120. On the other hand, when dirty water is poured through the pouring port 1220, the waste water can be poured out more thoroughly, reducing the amount of wastewater remaining in the tank 122, and further reducing the amount of odor generated.

[0115] like Figures 9 to 10 As shown, in one feasible embodiment, the waste collection assembly 120 further includes: a first seal 1210 disposed on the isolator 127 and located between the cover unit 128 and the isolator 127; and / or a second seal disposed between the plate 1231 and the housing 122; and / or a third seal disposed between the cover unit 128 and the housing 122.

[0116] In this technical solution, a first sealing element 1210 can be formed on the isolation element 127. The first sealing element 1210 abuts against the cover unit 128. Based on this, the gap between the isolation element 127 and the cover unit 128 can be sealed by the first sealing element 1210, which can reduce the probability of water vapor propagating between the cover unit 128 and the isolation element 127, and can better achieve gas-water separation.

[0117] In this technical solution, a second sealing element can be provided between the plate 1231 and the box 122. The sealing effect of the plate 1231 can be guaranteed by the second sealing element, which can reduce the probability of sewage backflow.

[0118] In some examples, the first seal 1210 can be a sealing strip, and the second and third seals can be sealing rings. The sealing strip and sealing ring can be used in combination with ribs to further improve the sealing effect.

[0119] like Figures 1 to 12 As shown, in one feasible embodiment, the waste collection assembly 120 further includes: a suction pipe 125, one end of which is close to the surface to be cleaned, and the other end which leads to the separation space 1221; wherein, the filter element 1232 at least surrounds a portion of the suction pipe 125.

[0120] This technical solution further provides a design for the dirt collection component 120. During the operation of the surface cleaning device, the negative pressure generated by the surface cleaning device acts on the suction pipe 125, allowing dirt to be supplied to the separation space 1221 through the suction pipe 125 and enter the area of ​​the filter element 1232. The dirt is then filtered by the filter element 1232, and the liquid, under the action of gravity, enters the liquid collection space 1222 through the through hole 1233. Solid waste is stored within the filter element 1232, thus completing solid-liquid separation. This design facilitates the direct supply of dirt to the separation space 1221.

[0121] In this technical solution, one end of the suction pipe 125 is positioned close to the surface to be cleaned, so that dirt only passes through the suction pipe 125 and accumulates in the dirt collection component 120. This minimizes the amount of dirt passing through other components such as the base component 110, thus ensuring the relative cleanliness of the base component 110 and other components.

[0122] like Figure 12 As shown, in one feasible embodiment, one end of the suction pipe 125 that is connected to the separation space 1221 extends into the separation space 1221.

[0123] In this technical solution, one end of the suction pipe 125 that is connected to the separation space 1221 extends into the separation space 1221. That is, the end of the suction pipe 125 that is connected to the separation space 1221 extends into the separation space 1221. The height of the outlet of the suction pipe 125 can be higher than the height of the plate 1231. Based on this, dirt will first pass through the outlet of the suction pipe 125 and then enter the filter element 1232 from a certain height. This can reduce the probability of dirt clogging the outlet of the suction pipe 125 and make the dirt enter the separation space 1221 more smoothly.

[0124] like Figure 14 and Figure 15 As shown, in one feasible embodiment, the surface cleaning device further includes a cleaning element 210, which is connected to the base assembly 110.

[0125] In this technical solution, the surface cleaning device may further include a cleaning component 210, which is connected to the base assembly 110. The cleaning component 210 is used to contact the surface to be cleaned and to move relative to the surface to be cleaned, thereby cleaning the surface. The cleaning component 210 may include a rotating roller brush, a reciprocating plate-shaped cleaning component 210, a rotating cleaning disc, etc. These specific embodiments capable of achieving cleaning are all within the protection scope of this application.

[0128] In this technical solution, the body 220 is connected to the dirt collection assembly 120 or the base assembly 110. The user can hold the body 220 to move the surface cleaning device to perform cleaning operations.
