[0022] The filter element at least surrounds a portion of the suction pipe.

[0023] In one feasible implementation, the waste collection assembly further includes:

[0024] The system includes a sewage inlet and an air outlet. The air outlet is connected to a negative pressure component. The sewage inlet uses negative pressure to suck up dirt from the surface to be cleaned.

[0043] This application includes at least the following beneficial effects:

[0044] 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 component is used to store dirt, such as solid dirt and dirty water. Because the dirt collection component is mounted on the base component, the distance between them is very short, resulting in a short dirt transport path. Firstly, this eliminates the need for long pipes, simplifying the structure. Secondly, it greatly reduces the probability of dirt accumulation in areas other than the dirt collection component, reducing odor generation and making the surface cleaning device more hygienic. Thirdly, it facilitates user cleaning of the dirt collection component, making maintenance of the surface cleaning device more convenient. Fourthly, regarding the counterweight of the surface cleaning device, when using a handheld surface cleaning device, placing the dirt collection component on the base component keeps it relatively far from the user's hand position, bringing the center of gravity closer to the base component. This increases the surface cleaning device's grip, improves cleaning ability, and makes it easier for the user to move the surface cleaning device, making its use more effortless.

[0045] The surface cleaning device provided in this application includes a dirt collection component comprising a housing and a solid-liquid separation unit. The solid-liquid separation unit is housed within the housing. Therefore, during the operation of the surface cleaning device, the dirt generated during cleaning can first enter the solid-liquid separation unit under negative pressure. The solid dirt and wastewater in the dirt are then separated by the solid-liquid separation unit. The wastewater enters the housing for storage, while the solid waste is stored in the solid-liquid separation unit. This achieves solid-liquid separation of dirt during the cleaning process.

[0046] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0067] 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.

[0068] 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 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.

[0069] 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.

[0070] like Figures 1 to 12 As shown, a surface cleaning device is provided according to a first aspect of the present application, comprising: a base assembly 110; a dirt collection assembly 120 disposed on the base assembly 110; the dirt collection assembly 120 includes a housing 122 and a solid-liquid separation unit 123 disposed inside the housing 122, wherein after dirt is separated by the solid-liquid separation unit 123, at least a portion of the solid dirt is stored in the solid-liquid separation unit 123, and the liquid dirt is stored in the lower space of the housing 122 through the solid-liquid separation unit 123.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] It is understandable that the majority of liquid contaminants are water, but due to the filtration level of the solid-liquid separation unit, the liquid contaminants may also contain some solid contaminants with smaller particle sizes. The liquid contaminants eventually collect in the lower space of the housing 122. On the one hand, the solid-liquid separation unit 123 can be designed using gravity flow, making the layout of the solid-liquid separation unit 123 simpler; on the other hand, it can reduce the probability of liquid contaminants overflowing.

[0076] like Figures 1 to 10 As shown, in one feasible embodiment, the volume of the housing 122 is 1680ml to 6000ml.

[0077] In this technical solution, structural parameters of the dirt collection component 120 are further provided. The volume of the dirt collection component 120 is between 1680ml and 6000ml. Based on this, on the one hand, it can be ensured that the dirt collection component 120 has a sufficient volume to hold enough dirt, ensuring cleaning efficiency, reducing maintenance frequency, and making the dirt collection component 120 more convenient to use. On the other hand, it can avoid the dirt collection component 120 having an excessively large volume, thereby reducing the weight of the surface cleaning device and facilitating its movement on the surface to be cleaned, making the surface cleaning device more convenient to use. It is understandable that if the volume of the dirt collection component 120 is less than 1680ml, the surface cleaning device may require too frequent maintenance and be inconvenient to use; while if the volume of the dirt collection component 120 is greater than 6000ml, the dirt collection component 120 may be too large, making it difficult for the surface cleaning device to move on the surface to be cleaned.

[0078] In some examples, the volume of the housing 122 can be 1800ml, 2100ml, 3200ml, 5000ml, 5500ml, etc.

[0079] like Figures 1 to 10 As shown, where Figure 1The direction of the middle arrow indicates the length, width and height of the box 122. In one possible embodiment, the length of the box 122 is 200ml to 300ml, the width is 120ml to 180ml and the height is 70ml to 130ml.

[0080] In this technical solution, the specifications and dimensions of the waste collection component 120 are further provided. The length of the box 122 is 200ml to 300ml, the width is 120ml to 180ml, and the height is 70ml to 130ml. Based on this, on the one hand, it ensures that the box 122 has a sufficiently large volume; on the other hand, it makes the box 122 flat, which lowers the center of gravity of the box 122, thereby suppressing the phenomenon of sewage surging inside the box 122, making the surface cleaning device more convenient to use.

[0081] Preferably, the length of the housing 122 is approximately 250ml, the width is approximately 170ml, and the height is 85ml or slightly lower. The overall height of the surface cleaning device has been verified to be 106ml or 90ml. The overall height of the surface cleaning device is less than 300ml to facilitate the surface cleaning device in performing cleaning operations.

[0082] Understandably, although this application provides a range for the length, width, and height of the tank 122, it should be noted that the tank 122 can be a non-standard cuboid, and the tank 122 typically needs to be designed with various clearances or protrusions based on actual conditions. The effective wastewater volume of the tank 122 is required to be ≥600ml, for example, 600ml / 720ml. When the surface cleaning device is equipped with auxiliary cleaning components 112 and roller brushes or other cleaning parts, the effective volume of wastewater accounts for approximately 11% of the total volume of the surface cleaning device. On the one hand, this percentage corresponds to an effective wastewater volume of ≥600ml, which can match the amount of wastewater generated during a single continuous cleaning operation, avoiding frequent emptying due to insufficient volume. On the other hand, the waste collection component 120 is mounted on the base component 110, resulting in a short distance between the waste collection component 120 and the base component 110. This shortens the dirt transport path, reduces wastewater retention and loss, and allows the 11% actual volume to fully store the wastewater. Furthermore, the size of the housing 122 is adapted to the floor brush structure, does not affect operation, and allows for maintenance only after covering a larger cleaning area, thereby reducing the maintenance frequency.

[0083] like Figure 7 , Figure 9 and Figure 10As shown, in one feasible embodiment, the solid-liquid separation unit 123 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.

[0084] 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. The solid-liquid separation unit 123 can be detachably connected to the housing 122. The plate 1231 can be located in the middle of the housing 122, dividing the housing 122 into an upper separation space 1221 and a lower waste liquid containing space 1222. The filter element 1232 can be mounted on the plate 1231. During the operation of the surface cleaning device, dirt is adsorbed onto the filter element 1232 under negative pressure. Then, under 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 accumulates within the filter element 1232, thus completing solid-liquid separation.

[0085] 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.

[0086] Understandably, during normal operation of the surface cleaning device, the separation space 1221 is located at the top of the waste liquid containing space 1222. That is to say, the dirt will 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.

[0087] like Figure 10 As shown, in one feasible embodiment, the ratio of the volume of the separation space 1221 to the volume of the sewage containing space 1222 is 1:1 to 4:1.

[0088] In this technical solution, the relationship between the separation space 1221 and the sewage containing space 1222 is further provided. The solvent ratio of the separation space 1221 and the sewage containing space 1222 is 1:1 to 4:1. On the one hand, this ensures that the surface cleaning device has a sufficiently large space to contain the sewage, thereby reducing the maintenance frequency of the surface cleaning device. On the other hand, it also ensures that the separation space 1221 has a sufficiently large volume, providing a sufficiently large separation space 1221 for solid waste and sewage, reducing the probability of sewage backflow, and ensuring the effect of solid-liquid separation.

[0089] like Figure 10 As shown, in one feasible embodiment, the volume of the waste liquid containing space 1222 is greater than or equal to 550 ml.

[0090] In this technical solution, the volume parameters of the sewage holding space 1222 are further provided. The volume of the sewage holding space 1222 is greater than or equal to 550ml. This setting ensures that the tank 122 can hold a sufficient amount of sewage, reducing the maintenance frequency of the surface cleaning device.

[0091] Preferably, the volume of the waste liquid containing space 1222 is greater than or equal to 600ml, such as 700ml, 650ml, 800ml, etc.

[0092] like Figure 3 , Figure 6 and Figure 10 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.

[0093] This technology further provides a design for a dirt collection assembly 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 into 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 perforation 1233. Solid waste is stored within the filter element 1232, thus achieving solid-liquid separation. This design facilitates the direct supply of dirt into the separation space 1221.

[0094] 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.

[0095] like Figure 10 As shown, in one feasible embodiment, the dirt collection assembly 120 further includes a dirt inlet 1251 and an air outlet 1261. The air outlet 1261 is connected to a negative pressure assembly. The dirt inlet 1251 uses negative pressure to suck up dirt from the surface to be cleaned. The distance between the dirt inlet 1251 and the air outlet 1261 and the surface to be cleaned is no more than 10 cm. In some embodiments, the height of the housing is 13 cm. The distance between the dirt inlet 1251 and the bottom of the housing can be 4 cm, 5 cm, or 7 cm, and the distance between the air outlet 1261 and the bottom of the housing can be 6 cm, 8 cm, or 9 cm. Because the distance between the bottom of the housing and the surface to be cleaned is very small, the overall distance between the dirt inlet 1251 and the air outlet 1261 and the surface to be cleaned can be controlled to be no more than 10 cm. This allows control over the overall height of the surface cleaning device and the length of the dirt transport path during dirt collection and storage, thereby reducing the workload and difficulty of cleaning and maintenance after use. In embodiments where the height of the housing is less than 13 cm, it is easier to control the distance between the inlet 1251 and the outlet 1261 and the surface to be cleaned to not exceed 10 cm, and usually not less than 3 cm, which will not be elaborated further here.

[0096] The waste collection assembly 120 includes a waste inlet 1251 and an air outlet 1261, and the air outlet 1261 is connected to the negative pressure assembly. Based on this, during the use of the waste collection assembly 120, the negative pressure assembly generates airflow. The airflow can adsorb dirt through the waste inlet 1251, and the dirt enters the waste collection assembly 120 for storage. Then, the airflow is discharged outside the waste collection assembly 120 through the air outlet 1261. The dirt collection component 120 provided in this application embodiment has a dirt inlet 1251 and an air outlet 1261 that are no more than 10 centimeters away from the surface to be cleaned. This allows the dirt collection component 120 to be installed closer to the ground, resulting in a short distance between the dirt collection component 120 and the dirt to be collected. This controls the length of the dirt transport path. On the one hand, it 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 component 120, reducing odor generation and making the use of the surface cleaning device equipped with the dirt collection component 120 more hygienic. Thirdly, it facilitates the user's cleaning of the dirt collection component 120, making the maintenance of the surface cleaning device more convenient. Fourthly, regarding the counterweight of the surface cleaning device equipped with the dirt collection component 120, when using the handheld surface cleaning device to perform cleaning operations, the distance between the dirt collection component 120 and the ground is reduced, allowing the dirt collection component 120 to be relatively far away from the user's hand position. This allows the center of gravity of the surface cleaning device to be closer to the base component 110, increasing the grip of the surface cleaning device, improving cleaning ability, and making it easier for the user to move the surface cleaning device, making the use of the surface cleaning device more effortless.

[0097] It is understandable that the distances between the inlet 1251 and the outlet 1261 and the surface to be cleaned refer to the distances along the height direction between the inlet 1251 and the surface to be cleaned, and between the outlet 1261 and the surface to be cleaned. In other words, it refers to the height of the inlet 1251 and the outlet 1261 from the ground.

[0098] It is understood that the waste collection assembly 120 may be a wastewater tank or an assembly that includes a wastewater tank, such as a detachable assembly that includes a wastewater tank, a roller brush cover 1240, and a wiper unit 1250.

[0099] In one feasible implementation, the inlet 1251 is an opening formed at one end of the suction pipe 125 leading to the separation space 1221, or the end of the suction pipe 125 leading to the separation space 1221 is provided with an inlet component, on which the inlet 1251 is formed.

[0100] This technical solution further provides a method for forming the inlet 1251. The inlet 1251 is designed to flexibly adapt to the connection requirements of the suction pipe 125 and the separation space 1221. Both methods ensure efficient transport of dirt to the separation space 1221. The suction pipe 125 is directly formed into an opening, simplifying the structure, reducing the number of parts, and lowering assembly and maintenance costs. Forming an opening through the inlet component allows for optimization of the inlet 1251's shape according to the characteristics of the dirt, improving dirt suction efficiency and preventing blockages. Both methods shorten the path of dirt from the pipe to the separation space 1221, reducing residue. Combined with the solid-liquid separation unit 123, this quickly achieves dirt separation, reduces odor generation, and ensures the overall hygiene and ease of use of the cleaning equipment.

[0101] like Figure 1 and Figure 10 As shown, in one feasible embodiment, the waste collection assembly 120 further includes: a cover unit 128, which is closably installed on the open side of the housing 122, and a receiving space is formed between the housing 122 and the cover unit 128 in the closed state; wherein, the waste inlet 1251 is provided on the housing 122; wherein, the air outlet 1261 is provided on the housing 122 or the cover unit 128.

[0102] This technical solution further provides the structural composition of the waste collection component 120. The waste collection component 120 may include a housing 122 and a cover unit 128. The cover unit 128 can seal the housing 122, allowing the airflow of the negative pressure component to better absorb the dirt, thereby improving the waste collection effect. A receiving space is formed between the housing 122 and the cover unit 128 in the closed state, which can store the dirt.

[0103] In this technical solution, the cover unit 128 is closable and installable on the open side of the box 122, which facilitates the maintenance of the box 122, such as facilitating the cleaning and rinsing of the box 122.

[0104] This technical solution further provides the arrangement positions of the sewage inlet 1251 and the air outlet 1261. The sewage inlet 1251 is positioned on the housing 122, allowing dirt to enter the housing 122 as quickly as possible. The air outlet 1261 can be positioned on the housing 122 to facilitate airflow within the housing 122 and its discharge. Alternatively, the air outlet 1261 can be positioned on the cover unit 128, which allows for a longer airflow path and further facilitates air-water separation.

[0105] In one feasible implementation, the waste collection assembly 120 further includes a separator 127, which is disposed between the housing 122 and the cover unit 128, for separating the waste inlet 1251 from the air outlet 1261.

[0106] 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 1261 under the action of airflow. Based on this, an isolation element 127 can be set on the plate 1231. The isolation element 127 blocks the filter element 1232, the dirt inlet 1251 and the air outlet 1261. 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 1261. By setting the isolation element 127, the length of the airflow path in the separation space 1221 is increased. With the longer propagation path, the probability of water vapor contaminating the negative pressure component can be further reduced, achieving a better air-water isolation effect.

[0107] like Figure 9 As shown, in one feasible embodiment, the distance between the spacer 127 and the side wall of the housing 122 is greater than or equal to 1 cm.

[0108] In this technical solution, the positional relationship between the isolation component 127 and the box 122 is further provided. The distance between the isolation component 127 and the side wall of the box 122 is greater than or equal to 1cm, which can avoid the flow channel being too narrow and avoid the fluid velocity in the flow channel being too high, thus carrying out water vapor and further improving the air-water isolation effect.

[0109] like Figure 9 As shown in the attached diagram, the shaded area represents the region where the spacer 127 is located. A1, A2, and A3 represent the distances between the spacer 127 and the side walls of the housing 122, and each value of A1, A2, and A3 is not less than 1 cm. Specifically, A1 can represent the distance between both ends of the spacer 127 and the left and right side walls of the housing 122. Figure 9As shown, the distances between the two ends of the isolator 127 and the side walls of the housing 122 can be equal, both denoted as A1. In other embodiments, the distances between the two ends of the isolator 127 and the side walls of the housing 122 can also be unequal, one represented by A1 and the other by A4 (not shown in the figure). A2 and A3 can represent the distances between the isolator 127 and the front and rear side walls of the housing 122, respectively. To rationally plan the separation space 1221 and ensure the solid-liquid separation effect and the gas-liquid separation effect, A2 can be equal to A3, or A2 can be slightly larger than A3, or A3 can be slightly larger than A2. A more uniform and rational space planning can also reduce the wind noise of gas flow in the separation space. To ensure the isolation effect of the isolator 127 on the inlet 1251 and the outlet 1261, A1 can be smaller than A2, and A1 can also be smaller than A3, so that the isolator 127 can have a certain length. Similarly, A4 can be smaller than A2, and A4 can also be smaller than A3. To reduce the flow velocity of contaminants at the through-hole 1233, improve the solid-liquid separation effect, and prevent water vapor from contaminating the negative pressure component, twice A1 can be greater than A2, and twice A1 can be greater than A3. Similarly, the sum of A1 and A4 can be greater than A2, and the sum of A1 and A4 can also be greater than A3. In this way, the flow velocity of the fluid at both ends of the isolation member 127, i.e., at the location of the through-hole 1233, can be reduced, facilitating the entry of contaminants into the through-hole 1233 and into the contaminant receiving space 1222.

[0110] 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.

[0111] 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.

[0112] like Figures 1 to 4 As shown, in one possible implementation, the plate 1231 and the spacer 127 are integrally and detachably connected to the housing 122.

[0113] 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.

[0114] like Figures 1 to 4 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.

[0115] 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.

[0116] like Figures 1 to 4 As shown, in one feasible embodiment, the isolator 127 is disposed on the plate 1231 for abutting against the cover unit 128. A fluid channel is formed between the isolator 127 and the inner wall of the housing 122. Dirt enters the through hole 1233 through the fluid channel and flows into the sewage containing space 1222. The ratio of the flow area of ​​the fluid channel to the flow area of ​​the suction pipe 125 is greater than or equal to 2. The fluid channel is connected to the through hole 1233, and the number of fluid channels is adapted to the number of through holes 1233.

[0117] This technical solution further provides the specific arrangement of the isolation element 127 and the flow method of dirt. During cleaning, the negative pressure causes dirt on the surface to be cleaned to enter the separation space 1221 through the suction pipe 125, while solid dirt is retained by the filter element 1232. Liquid dirt and some fine impurities flow along the plate 1231 and, upon contact with the isolation element 127, are guided and confined by it into the fluid channel formed between the isolation element 127 and the inner wall of the housing 122. Subsequently, the dirt flows smoothly through the fluid channel to the through holes 1233 on the plate 1231, and finally flows through the through holes 1233 into the waste liquid receiving space 1222 at the bottom of the housing 122 for storage. The number of fluid channels is matched with the number of through holes 1233 to ensure precise dirt flow. The flow area of ​​the fluid channels is not less than twice the flow area of ​​the suction pipe 125 to avoid the narrow channel causing excessive flow velocity and carrying out water vapor, thereby improving the air-water separation effect and reducing the risk of moisture absorption by the negative pressure component. The isolator 127 abuts against the cover unit 128, and the channel design extends the airflow path, further reducing odor generation. At the same time, the number of channels adapted to the through-hole 1233 ensures efficient transport of dirt and grime, avoids blockage, ensures continuous cleaning, and improves the reliability and ease of maintenance of the equipment.

[0118] In some examples, the number of fluid channels is equal to the setup example of via 1233.

[0119] like Figure 10 and Figure 6 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.

[0120] 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.

[0121] 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.

[0122] like Figure 1 and Figure 8 As shown, in some examples, the base assembly 110 includes: a housing 111 to which a waste collection assembly 120 is detachably connected; an auxiliary cleaning assembly 112; and a cleaning element 210 connected to the housing 111, with at least a portion of the cleaning element 210 disposed in front of the auxiliary cleaning assembly 112.

[0123] In this technical solution, the structure of the base assembly 110 is further provided. The base assembly 110 may include a housing 111, an auxiliary cleaning assembly 112, and a cleaning component 210. Based on this, during use, the cleaning component 210 and the surface to be cleaned need to move relative to each other, so that the cleaning component 210 can remove dirt from the surface to be cleaned. Then, under the negative pressure of the cleaning equipment, the dirt can enter the dirt collection assembly 120 through the auxiliary cleaning assembly 112, thus completing the collection of dirt.

[0124] It is understood that the cleaning component 210 can be a roller brush, a wiping board that can reciprocate in a linear motion, or a rotatable wiping tray. This application does not limit the specific style of the cleaning component 210, as long as the cleaning component 210 can move relative to the surface to be cleaned.

[0125] like Figure 4 and Figure 5 As shown, in some examples, the cleaning component 210 includes a roller brush; wherein, the cleaning device further includes: an auxiliary cleaning component 112, which is connected to the dirt collection component 120. The auxiliary cleaning component 112 includes: a liquid distribution plate 1122, a squeezing rib 1123, and a toothed scraper 1124. The outlet of the liquid distribution plate 1122 faces the roller brush and is used to supply liquid to the roller brush. The squeezing rib 1123 and the toothed scraper 1124 abut against the roller brush. The squeezing rib 1123 is located between the liquid distribution plate 1122 and the toothed scraper 1124.

[0126] In this technical solution, the cleaning component 210 may include a roller brush. By setting the roller brush, on the one hand, it is convenient to realize the mutual movement between the cleaning component 210 and the surface to be cleaned; on the other hand, it can improve the cleaning effect on stubborn dirt on the surface to be cleaned.

[0127] In this technical solution, the auxiliary cleaning component 112 is further provided. The auxiliary cleaning component 112 may include a liquid distribution plate 1122, a squeezing rib 1123, and a toothed scraper 1124. Based on this, during the operation of the cleaning equipment, the roller brush rotates relative to the housing 111. In normal operation, the roller brush first contacts the toothed scraper, then the squeezing rib 1123, and finally the liquid distribution plate 1122 delivers cleaning liquid to the roller brush. As the roller brush rotates continuously, solid dirt, such as human or pet hair, can become entangled on it. This entangled dirt will then interact with the toothed scraper 1124. 4. During contact, under the action of the scraper blade 1124, the tangled dirt is detached by the roller brush and collected into the dirt collection component 120 under negative pressure. Then, the roller brush contacts the squeezing rib 1123, which abuts against the roller brush, squeezing it and squeezing out the wastewater. Under negative pressure, the wastewater enters the dirt collection component 120 through the wastewater inlet 1251. Furthermore, the distribution plate 1122 evenly distributes the cleaning liquid onto the roller brush, which then contacts the surface to be cleaned, achieving cleaning while reducing water stains. It is understood that the liquid output through the distribution plate 1122 can be water, cleaning agent, or a mixture of both.

[0128] In some examples, the auxiliary cleaning component 112 can be connected to the waste collection component 120, so that the auxiliary cleaning component 112 and the waste collection component 120 can be disassembled simultaneously. For example, the auxiliary cleaning component 112 can be connected to the waste collection component 120 by a fixing structure such as screws.

[0129] like Figures 1 to 12 As shown, a cleaning device is provided according to a second aspect of the embodiments of this application, including: a surface cleaning device as described in any of the above-described body 220 schemes; and a body 220 connected to a base assembly 110.

[0130] The cleaning equipment provided in this application includes surface cleaning devices as described in any of the above technical solutions, and therefore possesses all the beneficial effects of the surface cleaning devices described in the above technical solutions.

[0131] In this technical solution, the cleaning equipment may also include a body 220 and a surface cleaning device. Users can hold the handle to move the cleaning equipment so that the base assembly 110 comes into contact with the surface to be cleaned, thereby achieving the cleaning of the surface.

[0132] In one feasible implementation, the cleaning device further includes: a clean water tank disposed within the body 220; and a power supply assembly disposed within the body 220, located on the side of the clean water tank opposite to the surface cleaning device.

[0133] This technical solution further provides the structural composition of the cleaning equipment, which may include a water tank and a power supply component. The water tank supplies water or cleaning fluid to the base assembly 110 of the surface cleaning device. The cleaning component 210 of the base assembly 110 then positions relative to the ground, allowing it to clean the floor. Simultaneously, a negative pressure component within the cleaning equipment provides negative pressure to the dirt collection component 120, enabling dirt collection. The power supply component provides power to the base assembly 110 and the negative pressure component. The water tank is located inside the body 220. Even with a significant distance between the water tank and the base assembly 110, residual water within the body 220 will not produce, or will produce, very little, odor. Furthermore, the power supply component is located on the side of the water tank away from the surface cleaning device, allowing for a more balanced configuration within the body 220 and more efficient use of space, resulting in a more compact cleaning equipment structure.
