Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings.

[0057] Please see Figures 1 to 3 This invention provides a floor brush assembly 10, comprising a housing 100, a waste liquid tank 200, and a brush head 300, wherein:

[0058] The outer casing 100 includes a main inlet 121 and a receiving space 110, and the main inlet 121 and the receiving space 110 are connected. Specifically, the outer casing 100 has a brush cavity 120 at its head position and a receiving space 110 at its middle position. The brush cavity 120 forms the main inlet 121 at the front position of the receiving space 110.

[0059] The waste liquid tank 200 includes a first inlet 210, which is typically located on the front side of the waste liquid tank 200, but can also be located on the top of the waste liquid tank 200. When the waste liquid tank 200 is placed in the receiving space 110, the position of the first inlet 210 corresponds to the position of the main inlet 121, thus connecting the first inlet 210 and the main inlet 121. The waste liquid tank 200 also includes a liquid-retaining structure 230, which at least partially restricts the movement of liquid waste from the first inlet 210. More precisely, after liquid waste enters the waste liquid tank 200 from the first inlet 210, the liquid-retaining structure 230 restricts the movement of liquid waste within the waste liquid tank 200, thereby keeping the liquid waste within the waste liquid tank 200.

[0060] The brush head 300 is located near the main inlet 121. More precisely, the brush head is cylindrical and rotatably disposed within the roller brush chamber 120. During rotation, the brush head 300 acts on the surface to be cleaned, such as the floor. The brush head 300 causes the liquid dirt on the surface to flow along the roller brush chamber 120 to the main inlet 121, and then enters the waste liquid tank 200 through the main inlet 121 and the first inlet 210. Thus, the waste liquid tank 200 completes the collection of liquid dirt.

[0061] It is understandable that a liquid retention structure 230 is provided on the inner side of the waste liquid tank 200. The liquid retention structure 230 can effectively restrict the movement of liquid waste in the waste liquid tank 200. With this arrangement, even if the floor brush assembly 10 shakes during operation, the waste liquid tank 200 can effectively prevent liquid waste from overflowing from the first inlet 210 by utilizing the liquid retention structure 230, thereby ensuring that the floor brush assembly 10 can work effectively.

[0062] Furthermore, during use, the liquid retention structure 230 effectively restricts the overflow of liquid dirt from the first inlet 210, so users do not need to frequently replace the waste liquid tank 200 or clean the liquid dirt in the waste liquid tank 200 to prevent liquid dirt from overflowing, thus ensuring the convenience of using the floor brush assembly 10.

[0063] In addition, when the user needs to replace or clean the waste liquid tank 200, even if the amount of liquid waste in the waste liquid tank 200 is large, the waste liquid tank 200 is equipped with a liquid retention structure 230, which can effectively restrict the movement of liquid waste. Therefore, when the user disassembles or replaces the waste liquid tank 200, there is no need to worry that the waste liquid in the waste liquid tank 200 will overflow from the first inlet 210, thus facilitating the replacement of the waste liquid tank 200.

[0064] It should be noted that the floor brush component 10 in this application is not limited to the treatment of liquid waste, but can also be applied to other scenarios. Therefore, the liquid retention structure 230 in this application solution is not limited to restricting the movement of liquid waste such as liquid water in the waste liquid tank 200, but can also be used to restrict the movement of other types of liquid waste.

[0065] In some embodiments, refer to Figure 2 and Figure 3 The outer casing 100 also includes an air extraction channel 130, which is typically located on the rear side of the accommodating space 110, with the specific arrangement depending on actual needs. The air extraction channel 130 forms an air extraction port 131 on the rear side of the inner wall of the accommodating space 110, thus connecting the air extraction channel 130 to the accommodating space 110. Simultaneously, the waste liquid tank 200 has a first outlet 220 located near the first inlet 210. When the waste liquid tank 200 is placed in the accommodating space 110, the location of the first outlet 220 corresponds to the location of the air extraction port 131, thus connecting the first outlet 220 to the air extraction port 131. Correspondingly, the waste liquid tank 200 is connected to the air extraction channel 130.

[0066] In practical applications, the air extraction channel 130 and the external cleaning unit 610 (see reference) Figure 6When the cleaning unit 610 is started, it generates suction force towards the waste liquid tank 200 through the air extraction channel 130. The inside of the waste liquid tank 200 is under negative pressure, thus creating suction force in the roller brush chamber 120. Therefore, when the brush head 300 is roller brushing the surface to be cleaned, liquid dirt is drawn into the waste liquid tank 200 through the main inlet 121 and the first inlet 210 under the action of suction force. Because the waste liquid tank 200 is equipped with a liquid retention structure 230, the liquid dirt is effectively retained in the waste liquid tank 200 after being drawn in, thus preventing liquid dirt from entering the cleaning unit 610 with the airflow and ensuring the safe use of the cleaning unit 610. Meanwhile, the liquid-retaining structure 230 effectively prevents liquid contaminants from entering the air extraction channel 130, thereby avoiding contamination of the air extraction channel 130 by liquid contaminants and ensuring the cleanliness of the floor brush assembly 10 during use.

[0067] In other possible embodiments, instead of the exhaust channel 130, a guide plate (not shown in the figure) is provided on the inner side of the roller brush cavity 120. One end of the guide plate is located on one side of the brush head 300, and the other end extends to the main inlet 121. With this configuration, the brush head 300 transfers liquid waste onto the guide plate by rotating. The liquid waste flows along the guide plate to the main inlet 121 and flows into the waste liquid tank 200 through the first inlet 210, thereby completing the collection of liquid waste.

[0068] In one possible embodiment, reference is made to... Figure 2 and Figure 3 The liquid-retaining structure 230 is a water-absorbing layer that adheres to the inner wall of the waste liquid tank 200. This water-absorbing layer is made of highly absorbent resin, sponge, or nylon, among other materials. It is understood that by using an absorbent layer that adheres to the inner wall of the waste liquid tank 200, the liquid-retaining structure 230 effectively retains liquid waste, thereby preventing it from overflowing from the first inlet 210 and the first outlet 220. It also effectively prevents liquid waste from entering the exhaust channel 130 along with the airflow.

[0069] Moreover, the liquid retention structure 230 adopts a water-absorbing layer. The water-absorbing layer has a simple structure and is easy to install on the inside of the waste liquid tank 200, which is beneficial for mass production of the waste liquid tank 200.

[0070] In addition, the cost of the absorbent layer is low, and correspondingly, the cost of the waste liquid tank 200 is also effectively reduced. The waste liquid tank 200 can be used for disposable consumables.

[0071] In other possible embodiments, the liquid-retaining structure 230 is a baffle structure (not shown in the figure) disposed in the waste liquid tank 200. The baffle structure can be an integrally formed structure within the waste liquid tank 200, or it can be a structure added to the waste liquid tank 200; this application does not specifically limit its nature. It is understood that by providing the baffle structure, after liquid waste enters the waste liquid tank 200, the baffle structure can effectively block the liquid waste from entering the waste liquid tank 200, thereby keeping the liquid waste within the waste liquid tank 200.

[0072] To reduce the amount of liquid contaminants entering the exhaust channel 130, in a first possible embodiment, the first inlet 210 is located on the side of the waste liquid tank 200, and the first outlet 220 is located on the top of the waste liquid tank 200. With this arrangement, after the liquid contaminants enter the waste liquid tank 200 through the first inlet 210 under the suction force, the liquid contaminants are highly likely to hit the side plate of the waste liquid tank 200 facing the first outlet 220. Since the first outlet 220 is located on the top of the waste liquid tank 200, this effectively reduces the amount of liquid contaminants entering the exhaust channel 130 through the first outlet 220, thereby ensuring the cleanliness of the exhaust channel 130.

[0073] In a second possible embodiment, both the first inlet 210 and the first outlet 220 are located at the top of the waste liquid tank 200. With this arrangement, after liquid waste enters the waste liquid tank 200 through the first inlet 210 under suction, it is highly likely to hit the bottom of the waste liquid tank 200. Furthermore, since the first outlet 220 is located at the top of the waste liquid tank 200, this effectively reduces the likelihood of liquid waste entering the suction channel 130 through the first outlet 220, thus ensuring the cleanliness of the suction channel 130.

[0074] In a third possible embodiment, the first inlet 210 and the first outlet 220 are located on opposite sides of the waste liquid tank 200, and the orientation of the first inlet 210 is offset from that of the first outlet 220. With this arrangement, after liquid waste enters the waste liquid tank 200 through the first inlet 210 under suction, the liquid waste is highly likely to hit the side plate of the waste liquid tank 200 facing the first outlet 220. However, since the location of the liquid waste hitting the first outlet 220 is offset from its position, this effectively reduces the likelihood of liquid waste entering the suction channel 130 through the first outlet 220, thereby ensuring the cleanliness of the suction channel 130.

[0075] In some embodiments, refer to Figure 3 and Figure 4The liquid-retaining structure 230 is an absorbent layer that adheres to the inner wall of the waste liquid tank 200. The absorbent layer can be located on the bottom wall of the waste liquid tank 200, or on the side wall of the waste liquid tank 200. Alternatively, the absorbent layer can be located on both the bottom and side walls of the waste liquid tank 200. When the absorbent layer is located on the side wall of the waste liquid tank 200, it can be located only on a portion of the side wall, without needing to adhere to the entire side wall of the waste liquid tank 200. The specific arrangement depends on actual needs. For example, if it is used for daily household floor cleaning, an absorbent layer is only needed on a portion of the side of the waste liquid tank 200, which is sufficient to meet the requirements and save on the cost of the waste liquid tank 200. The waste liquid tank 200 is suitable for use as a disposable consumable.

[0076] Furthermore, the waste liquid tank 200 has an absorbent layer on at least the side opposite to the first inlet 210. Specifically, the first inlet 210 is located on the side of the waste liquid tank 200, and the waste liquid tank 200 has an absorbent layer on at least the side facing the first inlet 210; or, the absorbent layer is attached to the side wall of the waste liquid tank 200 away from the first inlet 210. Alternatively, the first inlet 210 is located at the top of the waste liquid tank 200, and the bottom of the waste liquid tank 200 has at least an absorbent layer.

[0077] Understandably, the absorbent layer is positioned opposite the first inlet 210. With this arrangement, when liquid waste enters the waste liquid tank 200 from the first inlet 210 under the action of suction, the liquid waste will most likely hit the absorbent layer, allowing it to quickly adhere to the absorbent layer. This prevents the liquid waste from entering the air extraction channel 130 with the airflow, thus ensuring the cleanliness of the air extraction channel 130.

[0078] In some embodiments, refer to Figures 1 to 3 The waste liquid tank 200 is configured to be detachably connected to the receiving space 110. For example, the waste liquid tank 200 has snap-fit ​​structures 140 on both sides of the receiving space 110, and the left and right side walls of the waste liquid tank 200 have slots 240. Therefore, after the waste liquid tank 200 is placed in the receiving space 110, the snap-fit ​​structures 140 on both sides of the receiving space 110 just fit into the slots 240, thereby keeping the waste liquid tank 200 within the receiving space 110. If it is necessary to remove the waste liquid tank 200, the operator only needs to release the snap-fit ​​structures 140 from the waste liquid tank 200, and the user can easily replace the waste liquid tank 200 of the floor brush assembly 10 with a new waste liquid tank 200 to ensure the normal use of the floor brush assembly 10.

[0079] Among them, the waste liquid tank 200 is a disposable consumable, or more precisely, a disposable waste liquid tank 200. Users can flexibly replace the waste liquid tank 200 as needed. For example, after each waste liquid tank 200 has been used for one to three days, users can replace it with a new waste liquid tank 200. Accordingly, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0080] To illustrate that the waste liquid tank 200 is a disposable item, in some embodiments, the waste liquid tank 200 only has an inlet and outlet (the aforementioned first inlet 210 and first outlet 220). Specifically, the surface of the waste liquid tank 200 only has the first inlet 210, or the surface of the waste liquid tank 200 only has the first inlet 210 and the first outlet 220. Correspondingly, the waste liquid tank 200 does not have a replacement port 250 or other openings for other purposes, such as for replacing the absorbent layer.

[0081] To further clarify, the waste liquid tank 200 is a non-detachable, enclosed container. Specifically, the waste liquid tank 200 is a closed container, meaning its bottom, sides, and top are all sealed; that is, the waste liquid tank 200 has no openings other than the inlet and outlet. Furthermore, the waste liquid tank 200 is a single, enclosed structure, not a container composed of multiple interconnected shells. Therefore, in this application, the waste liquid tank 200 uses a non-detachable, enclosed container, making it a disposable consumable. Users cannot replace the absorbent layer within the waste liquid tank 200, thus clearly indicating that the floor brush assembly 10 uses a disposable waste liquid tank 200. Consequently, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0082] To further illustrate that the waste liquid tank 200 is a disposable consumable, in some embodiments, the waste liquid tank 200 is a blow-molded box. It is understood that by using a blow-molded box, the waste liquid tank 200 becomes a non-detachable, closed box, and its surface only has an inlet and outlet. Consequently, the waste liquid tank 200 cannot have a replacement port 250 for replacing the absorbent layer. Therefore, it is clearly indicated that the floor brush assembly 10 uses a disposable waste liquid tank 200. Consequently, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use. Furthermore, since the waste liquid tank 200 is blow-molded, its cost is lower, and its thickness can be made very thin, making it suitable as a disposable consumable.

[0083] In other possible embodiments, refer to Figure 5The waste liquid tank 200 is a reusable container. Specifically, the waste liquid tank 200 is configured to be detachably connected to the accommodating space 110, for example, the waste liquid tank 200 is snap-fitted to the accommodating space 110 of the outer shell 100. The waste liquid tank 200 also has a replacement port 250, through which the absorbent layer can be replaced. The waste liquid tank 200 typically also has a sealing cap 260 at the replacement port 250 to ensure the sealing effect of the waste liquid tank 200.

[0084] Understandably, the waste liquid tank 200 is also equipped with a replacement port 250 and is detachably connected to the floor brush assembly 10. When there is a large amount of liquid in the waste liquid tank 200, and the liquid-retaining structure 230 in the waste liquid tank 200 can no longer guarantee a complete retention effect on the liquid, the user can disassemble the waste liquid tank 200 from the floor brush assembly 10. After the waste liquid tank 200 is disassembled, the liquid-retaining structure 230 can be replaced or cleaned through the replacement port 250, depending on the actual needs. For example, if the liquid-retaining structure 230 of the waste liquid tank 200 is an absorbent layer, the user can replace the absorbent layer, and the replaced waste liquid tank 200 can be reinstalled into the floor brush assembly 10 for use. If the liquid retention structure 230 of the waste liquid tank 200 is a baffle structure set in the waste liquid tank 200, after the user disassembles the waste liquid tank 200, the user only needs to clean the baffle structure through the replacement port 250. After cleaning, the waste liquid tank 200 can be reinstalled into the floor brush assembly 10 for use.

[0085] In some embodiments, the housing 100 is provided with a loading / unloading port communicating with the accommodating space 110. The loading / unloading port can be located at the bottom of the floor brush assembly 10. With this configuration, the waste liquid tank 200 is essentially hidden inside the housing 100 during application, thus ensuring the aesthetics of the floor brush assembly 10. Alternatively, the loading / unloading port can also be located at the top of the floor brush assembly 10. With this configuration, the waste liquid tank 200 can be directly replaced from the top of the floor brush assembly 10, making the floor brush assembly 10 more convenient to use.

[0086] In some embodiments, refer to Figure 2 and Figure 3 The floor brush assembly 10 also includes a filter element 400, which can be made of HEPA filter paper or the like, and is disposed within the air extraction channel 130. Simultaneously, along the conveying direction of the air extraction channel 130, the filter element 400 is arranged in a folded state within the air extraction channel 130. Of course, the filter element 400 can also be filled into the air extraction channel 130 in other ways; this application does not limit the filter element 400 to being filled into the air extraction channel 130 only in a folded manner.

[0087] It is understandable that by installing a filter 400 in the air extraction channel 130, a small amount of dirt may still enter the air extraction channel 130 when the airflow passes through the waste liquid tank 200, especially dust or various tiny debris. Therefore, installing a filter 400 in the air extraction channel 130 can effectively filter out the dirt mixed in the airflow, so as to prevent the dirt from entering the cleaning host 610 with the airflow, thereby ensuring the safety of the cleaning host 610.

[0088] Furthermore, the filter element 400 is folded and placed inside the air extraction channel 130. This arrangement allows the filter element 400 to effectively filter out dirt mixed in with the airflow. At the same time, the filter element 400 will not significantly affect the suction force of the cleaning host 610 to the waste liquid tank 200 through the air extraction channel 130, thereby ensuring that the floor brush assembly 10 can effectively extract the liquid dirt from the brush head 300.

[0089] It should be noted that by setting a liquid-retaining structure 230 in the waste liquid tank 200, after liquid contaminants enter the waste liquid tank 200 with the airflow, the liquid-retaining structure 230 restricts the movement of liquid contaminants in the waste liquid, thereby preventing liquid contaminants from flowing to the filter paper and thus avoiding excessive adhesion of liquid contaminants to the filter paper. Therefore, the filter paper can maintain good air permeability, thereby ensuring that the cleaning unit 610 maintains a good suction effect on the waste liquid tank 200 through the air extraction channel 130.

[0090] In a further embodiment, the first outlet 220 is located at the top of the waste liquid tank 200, and the air extraction port 131 of the air extraction channel 130 is located just above the first outlet 220. Thus, the first outlet 220 is connected to the air extraction channel 130, that is, the waste liquid tank 200 is connected to the air extraction channel 130. At the same time, the filter element 400 is at least partially located at the port of the air extraction channel 130 near the first outlet 220. Therefore, this part of the filter element 400 is located just above the first outlet 220 to filter the airflow that has just entered the air extraction channel 130.

[0091] Understandably, the filter element 400 is positioned directly above the first outlet 220. This arrangement allows the filter element 400 to effectively block liquid contaminants entering the exhaust channel 130. Since the first outlet 220 is located at the top of the waste liquid tank 200, the liquid contaminants filtered by the filter element 400 fall back into the waste liquid tank 200 under gravity. Therefore, this arrangement of the filter element 400 effectively prevents liquid contaminants from entering the exhaust channel 130 and reduces the amount of liquid contaminants adhering to its surface. Furthermore, the folded design of the filter element 400 within the exhaust port 131 of the exhaust channel 130 facilitates the return of liquid contaminants adhering to the filter element 400 to the waste liquid tank 200.

[0092] This application also discloses a floor brush component 10, as shown in the reference. Figures 1 to 3 It includes a housing 100, a waste liquid tank 200, and a brush head 300, wherein:

[0093] The outer casing 100 includes a main inlet 121 and a receiving space 110, and the main inlet 121 and the receiving space 110 are connected. Specifically, the outer casing 100 has a brush cavity 120 at its head position and a receiving space 110 at its middle position. The brush cavity 120 forms the main inlet 121 at the front position of the receiving space 110.

[0094] The waste liquid tank 200 includes a first inlet 210, which is usually located on the front side of the waste liquid tank 200, or it can be located on the top of the waste liquid tank 200. When the waste liquid tank 200 is placed in the accommodating space 110, the position of the first inlet 210 is exactly the same as the position of the main inlet 121, thus the first inlet 210 is connected to the main inlet 121.

[0095] The brush head 300 is located near the main inlet 121. More precisely, the brush head is cylindrical and rotatably disposed within the roller brush chamber 120. During rotation, the brush head 300 acts on the surface to be cleaned, such as the floor. The brush head 300 causes the liquid dirt on the surface to flow along the roller brush chamber 120 to the main inlet 121, and then enters the waste liquid tank 200 through the main inlet 121 and the first inlet 210. Thus, the waste liquid tank 200 completes the collection of liquid dirt.

[0096] The waste liquid tank 200 is detachably connected to the accommodating space 110 so that the unused waste liquid tank 200 can be replaced for the floor brush assembly 10; the waste liquid tank 200 is a disposable and non-recyclable tank.

[0097] Specifically, the waste liquid tank 200 is configured to be detachably connected to the receiving space 110. For example, the waste liquid tank 200 has snap-fit ​​structures 140 on both sides of the receiving space 110, and the left and right side walls of the waste liquid tank 200 have slots 240. Therefore, after the waste liquid tank 200 is placed in the receiving space 110, the snap-fit ​​structures 140 on both sides of the receiving space 110 are just locked into the slots 240, thus keeping the waste liquid tank 200 within the receiving space 110. If it is necessary to remove the waste liquid tank 200, the operator only needs to release the snap-fit ​​structures 140 from the waste liquid tank 200, and the user can easily replace the waste liquid tank 200 of the floor brush assembly 10 with a new waste liquid tank 200 to ensure the normal use of the floor brush assembly 10.

[0098] The waste liquid tank 200 is a disposable consumable, or more precisely, a disposable waste liquid tank 200, meaning it is not reusable. For example, after one to three days of use, the user can replace each waste liquid tank 200 with a new one. Accordingly, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0099] To illustrate that the waste liquid tank 200 is a disposable item, in some embodiments, the waste liquid tank 200 only has an inlet and outlet. Specifically, the surface of the waste liquid tank 200 is only provided with a first inlet 210, or the surface of the waste liquid tank 200 is only provided with a first inlet 210 and a first outlet 220. Correspondingly, the waste liquid tank 200 is not provided with a replacement port 250 or other openings for other purposes, such as for replacing the absorbent layer.

[0100] To further clarify, the waste liquid tank 200 is a non-detachable, enclosed container. Specifically, the waste liquid tank 200 is a closed container, meaning its bottom, sides, and top are all sealed; that is, the waste liquid tank 200 has no openings other than the inlet and outlet. Furthermore, the waste liquid tank 200 is a single, enclosed structure, not a container composed of multiple interconnected shells. Therefore, in this application, the waste liquid tank 200 uses a non-detachable, enclosed container, making it a disposable consumable. Users cannot replace the absorbent layer within the waste liquid tank 200, thus clearly indicating that the floor brush assembly 10 uses a disposable waste liquid tank 200. Consequently, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0101] To further illustrate that the waste liquid tank 200 is a disposable consumable, in some embodiments, the waste liquid tank 200 is a blow-molded box. It is understood that by using a blow-molded box, the waste liquid tank 200 becomes a non-detachable, closed box, and its surface only has an inlet and outlet. Consequently, the waste liquid tank 200 cannot have a replacement port 250 for replacing the absorbent layer. Therefore, it is clearly indicated that the floor brush assembly 10 uses a disposable waste liquid tank 200. Consequently, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use. Furthermore, since the waste liquid tank 200 is blow-molded, its cost is lower, and its thickness can be made very thin, making it suitable for use as a disposable consumable.

[0102] In some embodiments, refer to Figures 2 to 4The outer casing 100 also includes an air extraction channel 130, which is typically located on the rear side of the accommodating space 110, with the specific arrangement depending on actual needs. The air extraction channel 130 forms an air extraction port 131 on the rear side of the inner wall of the accommodating space 110, thus connecting the air extraction channel 130 to the accommodating space 110. Simultaneously, the waste liquid tank 200 has a first outlet 220 located near the first inlet 210. When the waste liquid tank 200 is placed in the accommodating space 110, the location of the first outlet 220 coincides with the location of the air extraction port 131, thus connecting the first outlet 220 to the air extraction port 131. Correspondingly, the waste liquid tank 200 is connected to the air extraction channel 130.

[0103] In practical applications, the suction channel 130 is connected to an external cleaning unit 610 (not shown in the figure). When the cleaning unit 610 is started, it generates suction force towards the waste liquid tank 200 through the suction channel 130. The inside of the waste liquid tank 200 is under negative pressure, thus creating suction force in the roller brush chamber 120. Therefore, when the brush head 300 is roller brushing the surface to be cleaned, liquid dirt is drawn into the waste liquid tank 200 through the main inlet 121 and the first inlet 210 under the action of suction force. Furthermore, because the waste liquid tank 200 has a liquid-retaining structure 230 inside, the liquid dirt is effectively retained in the waste liquid tank 200 after being drawn in, thus preventing liquid dirt from entering the cleaning unit 610 with the airflow and ensuring the safe use of the cleaning unit 610. Meanwhile, the liquid-retaining structure 230 effectively prevents liquid contaminants from entering the air extraction channel 130, thereby avoiding contamination of the air extraction channel 130 by liquid contaminants and ensuring the cleanliness of the floor brush assembly 10 during use.

[0104] In other possible embodiments, instead of the exhaust channel 130, a guide plate (not shown in the figure) is provided on the inner side of the roller brush cavity 120. One end of the guide plate is located on one side of the brush head 300, and the other end extends to the main inlet 121. With this configuration, the brush head 300 transfers liquid waste onto the guide plate by rotating. The liquid waste flows along the guide plate to the main inlet 121 and flows into the waste liquid tank 200 through the first inlet 210, thereby completing the collection of liquid waste.

[0105] In one possible embodiment, the waste liquid tank 200 is provided with a liquid-retaining structure 230, which is a water-absorbing layer attached to the inner wall of the waste liquid tank 200. The water-absorbing layer is made of highly absorbent resin, sponge, or nylon, etc. It is understood that by using a water-absorbing layer attached to the inner wall of the waste liquid tank 200, the liquid-retaining structure 230 has a good retention effect on liquid waste, thereby effectively preventing liquid waste from overflowing from the first inlet 210 and the first outlet 220, and also effectively preventing liquid waste from entering the exhaust channel 130 with the airflow.

[0106] Moreover, the liquid retention structure 230 adopts a water-absorbing layer. The water-absorbing layer has a simple structure and is easy to install on the inside of the waste liquid tank 200, which is beneficial for mass production of the waste liquid tank 200.

[0107] In addition, the cost of the absorbent layer is low, and correspondingly, the cost of the waste liquid tank 200 is also effectively reduced. The waste liquid tank 200 can be used for disposable consumables.

[0108] In other possible embodiments, the liquid-retaining structure 230 is a baffle structure disposed in the waste liquid tank 200. The baffle structure can be an integrally formed structure within the waste liquid tank 200, or it can be a structure added to the waste liquid tank 200; this application does not specifically limit its application. It is understood that by providing the baffle structure, after liquid waste enters the waste liquid tank 200, the baffle structure can effectively block the liquid waste from entering the waste liquid tank 200, thereby keeping the liquid waste within the waste liquid tank 200.

[0109] This application also discloses a waste liquid tank 200, which is applied to the floor brush assembly 10. The waste liquid tank 200 is provided with a liquid retention structure 230. The waste liquid tank 200 is provided with an inlet and an outlet (the first inlet 210 and the first outlet 220 mentioned above). When the waste liquid tank 200 is applied to the floor brush assembly 10, waste liquid enters the waste liquid tank through the inlet and an outlet.

[0110] Understandably, the waste liquid tank 200 is also equipped with a liquid retention structure 230. The liquid retention structure 230 at least partially restricts the movement of liquid waste from the inlet and outlet. More precisely, after the liquid waste enters the waste liquid tank 200 from the inlet and outlet, the liquid retention structure 230 has a restrictive effect on the liquid waste, thereby effectively restricting the movement of liquid waste in the waste liquid tank 200 so that the liquid waste is kept in the waste liquid tank 200.

[0111] During application, a liquid retention structure 230 is provided on the inner side of the waste liquid tank 200. The liquid retention structure 230 can effectively restrict the movement of liquid waste in the waste liquid tank 200. With this configuration, even if the floor brush assembly 10 shakes during operation, the waste liquid tank 200 can effectively prevent liquid waste from overflowing from the inlet and outlet by means of the liquid retention structure 230, thereby ensuring that the floor brush assembly 10 can work effectively.

[0112] Furthermore, during use, the liquid retention structure 230 effectively restricts the overflow of liquid waste from the inlet and outlet, so users do not need to frequently replace the waste liquid tank 200 or clean the liquid waste tank 200 to prevent liquid waste from overflowing, thus ensuring the convenience of using the floor brush assembly 10.

[0113] In addition, when the user needs to replace or clean the waste liquid tank 200, even if the amount of liquid waste in the waste liquid tank 200 is large, the waste liquid tank 200 is equipped with a liquid retention structure 230, which can effectively restrict the movement of liquid waste. Therefore, when the user disassembles or replaces the waste liquid tank 200, there is no need to worry about the waste liquid in the waste liquid tank 200 overflowing from the inlet and outlet, thus facilitating the replacement of the waste liquid tank 200.

[0114] The waste liquid tank 200 is a disposable consumable, or more precisely, a disposable waste liquid tank 200, meaning it is not reusable. For example, after one to three days of use, the user can replace each waste liquid tank 200 with a new one. Accordingly, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0115] To illustrate that the waste liquid tank 200 is a disposable item, in some embodiments, the waste liquid tank 200 only has an inlet and outlet (the first inlet 210 and the first outlet 220 mentioned above). Specifically, the surface of the waste liquid tank 200 only has an inlet and outlet, or the surface of the waste liquid tank 200 only has an inlet and outlet. Correspondingly, the waste liquid tank 200 does not have a replacement port 250 or other openings for other purposes, such as for replacing the absorbent layer.

[0116] To further clarify, the waste liquid tank 200 is a non-detachable, enclosed container. Specifically, the waste liquid tank 200 is a closed container, meaning its bottom, sides, and top are all sealed; that is, the waste liquid tank 200 has no openings other than the inlet and outlet. Furthermore, the waste liquid tank 200 is a single, enclosed structure, not a container composed of multiple interconnected shells. Therefore, in this application, the waste liquid tank 200 uses a non-detachable, enclosed container, making it a disposable consumable. Users cannot replace the absorbent layer within the waste liquid tank 200, thus clearly indicating that the floor brush assembly 10 uses a disposable waste liquid tank 200. Consequently, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0117] From another perspective, the waste liquid tank 200 is a disposable consumable. In some embodiments, the waste liquid tank 200 is a blow-molded box. It is understood that the waste liquid tank 200 is a blow-molded box, making it a non-detachable, closed box. Furthermore, the surface of the waste liquid tank 200 only has an inlet and outlet. Consequently, the waste liquid tank 200 cannot have a replacement port 250 for replacing the absorbent layer. Therefore, it is further clarified that the floor brush assembly 10 uses a disposable waste liquid tank 200. Accordingly, the waste liquid tank 200 does not need to be reused after use, making the floor brush assembly 10 more convenient to use.

[0118] This application also discloses a floor scrubbing machine, including the aforementioned floor brush assembly 10.

[0119] In one possible embodiment, reference is made to... Figures 2 to 4 The outer casing 100 is provided with an air extraction channel 130, and the air extraction channel 130 forms an air extraction port 131 on the inner wall of the accommodating space 110; at the same time, the surface of the waste liquid tank 200 is provided with a first outlet 220, and when the waste liquid tank 200 is placed in the accommodating space 110, the air extraction port 131 is connected to the first outlet 220. The floor brush assembly 10 also includes a connector 500, which is rotatably connected to the outer casing 100, and the inner end of the connector 500 is connected to the air extraction channel 130; and the floor scrubber also includes an operating handle 600, on which a cleaning unit 610 is provided, and the operating handle 600 is connected to the outer end of the connector 500, and the cleaning unit 610 is connected to the connector 500 through a channel on the inner side of the operating handle 600.

[0120] In practical applications, the suction channel 130 is connected to the external cleaning unit 610. When the cleaning unit 610 is started, it generates suction force towards the waste liquid tank 200 through the suction channel 130. The inside of the waste liquid tank 200 is under negative pressure, thus creating suction force in the roller brush chamber 120. Therefore, when the brush head 300 is roller brushing the surface to be cleaned, liquid dirt is drawn into the waste liquid tank 200 through the main inlet 121 and the first inlet 210 under the action of suction force. Furthermore, because the waste liquid tank 200 has a liquid-retaining structure 230 inside, the liquid dirt is effectively retained in the waste liquid tank 200 after being drawn in, thus preventing liquid dirt from entering the cleaning unit 610 with the airflow and ensuring the safe use of the cleaning unit 610. Meanwhile, the liquid-retaining structure 230 effectively prevents liquid contaminants from entering the air extraction channel 130, thereby avoiding contamination of the air extraction channel 130 by liquid contaminants and ensuring the cleanliness of the floor brush assembly 10 during use.

[0121] In other possible embodiments, instead of the cleaning host 610, a guide plate (not shown in the figure) is provided on the inner side of the roller brush cavity 120. One end of the guide plate is located on one side of the brush head 300, and the other end extends to the main inlet 121. With this configuration, the brush head 300 transfers liquid dirt to the guide plate by rotating. The liquid dirt flows along the guide plate to the main inlet 121 and flows into the waste liquid tank 200 through the first inlet 210, thereby completing the collection of liquid dirt.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
