Description

Technical Field

[0001] This disclosure relates to the field of cleaning systems, and more specifically to a cleaning device and a cleaning system. Background Technology

[0002] In existing technologies, when the base station and the water tank assembly are connected, the base station can inject water into the water tank body of the water tank assembly. After the water tank assembly is filled with water, the residual liquid at the interface of the water tank assembly is prone to dripping onto the ground, causing the ground to become dirty and wasting water, resulting in a poor user experience. Summary of the Invention

[0003] In view of this, the present disclosure provides a cleaning device that helps reduce the occurrence of liquid dripping onto the ground, keeps the ground clean and tidy, saves water, and improves the user experience.

[0004] This disclosure also provides a cleaning system, including the cleaning equipment described above.

[0005] A cleaning device according to an embodiment of this disclosure includes: a body, the body having a grip for a user to grasp and push; a floor brush assembly, the floor brush assembly being rotatably connected to the body, the floor brush assembly including a floor brush body and a roller brush; the floor brush body having an installation space and a suction channel, the bottom of the installation space being open; the installation space communicating with one end of the suction channel; the roller brush being rotatably disposed within the installation space; and a clean water tank assembly, the clean water tank assembly being disposed on the floor brush body; the clean water tank assembly including a clean water tank body, the clean water tank body having a water receiving channel, a water storage chamber, and a water collection channel, the water receiving... The channel provides a channel for injecting water into the water storage chamber. One end of the water receiving channel is provided with a connector for connecting to an external water supply, and the other end is provided with a water inlet valve for connecting to the water storage chamber. The water collection channel is used to recover residual water in the water receiving channel. One end of the water collection channel is provided with a water collection port for connecting to the water receiving channel, and the other end is connected to the installation space. A suction motor assembly is connected to the other end of the suction channel. When the suction motor assembly is working, the installation space is created by the suction channel, which in turn causes the water collection channel to generate suction for the residual water in the water receiving channel.

[0006] According to the cleaning equipment of this disclosure, a water collection channel is used to recover residual water in the water receiving channel. One end of the water collection channel is provided with a water inlet for connecting to the water receiving channel, and the other end is connected to the installation space. The suction motor assembly is connected to the other end of the suction channel. When the suction motor assembly is working, the suction channel creates a negative pressure in the installation space, thereby causing the water collection channel to generate suction for the residual water in the water receiving channel. When the suction motor assembly generates negative pressure, both the installation space and the suction channel will generate negative pressure, driving the liquid into the wastewater tank. Since one end of the water collection channel is connected to the installation space, the negative pressure generated by the suction motor assembly can drive the water collected in the water collection channel to be discharged onto the surface of the roller brush, realizing the recovery and reuse of the liquid remaining in the water receiving channel. This reduces the occurrence of liquid dripping onto the ground when the water supply assembly and the clean water tank assembly are separated, keeping the ground clean and tidy, and also helps to save water.

[0007] In some embodiments of this disclosure, one end of the water collection channel is provided with a drainage channel, the outlet of the drainage channel is located on the inner wall of the installation space, and the vertical projection of the roller brush on the plane where the outlet of the drainage channel is located overlaps with the outlet of the drainage channel.

[0008] In some embodiments of this disclosure, the water collection channel is located below the water receiving channel, and the bottom wall of the water collection channel extends downwards along the direction from the water inlet to the inlet of the drainage channel.

[0009] In some embodiments of this disclosure, the water receiving channel includes a first segment and a second segment. The first segment has the connecting port. The water inlet valve is disposed on the portion of the water receiving channel excluding the first segment. The second segment is connected to the end of the first segment opposite to the connecting port. The cross-sectional area of ​​the second segment is smaller than that of the first segment. In the direction from the first segment to the second segment, the cross-sectional area of ​​the first segment gradually decreases.

[0010] In some embodiments of this disclosure, the end of the second segment away from the first segment is provided with an abutment, the water inlet valve is provided on the side of the abutment opposite to the first segment, the end of the abutment facing the first segment is provided with a trigger protrusion, and the water collection port is located on the side of the trigger protrusion facing the first segment.

[0011] In some embodiments of this disclosure, the abutment includes: a plurality of ribs, the plurality of ribs extending in different directions and intersecting at a junction, a plurality of sub-ports for flow defined between the plurality of ribs, and the trigger protrusion disposed at the junction.

[0012] In some embodiments of this disclosure, the clean water tank body includes: a tank body having a water storage cavity and a water receiving channel, the tank body having a collection cavity having a water collection port, the bottom of the collection cavity being open to form an open opening; a bottom plate detachably disposed at the open opening, the bottom plate and the inner wall of the collection cavity forming the water collection channel; and a sealing ring disposed between the bottom plate and the tank body for sealing the open opening.

[0013] In some embodiments of this disclosure, the clean water tank body has an exhaust port, which is connected to the water storage chamber; the clean water tank assembly further includes: an air vent valve, which is movably disposed at the exhaust port along the axial direction of the exhaust port, and the air vent valve is unidirectionally open from the inside of the water storage chamber to the outside of the water storage chamber.

[0014] A cleaning system according to an embodiment of the present disclosure includes: a base station having a water supply component for connecting to the water inlet channel; and the cleaning device described above, wherein the cleaning device is detachably disposed on the base station.

[0015] According to the cleaning system of this disclosure, by setting up the above-mentioned cleaning equipment, the water collection channel is used to recover residual water in the water receiving channel. One end of the water collection channel is provided with a water collection port for connecting to the water receiving channel, and the other end is used to connect to the installation space. The suction motor assembly is connected to the other end of the suction channel. When the suction motor assembly is working, the installation space is generated by the suction channel, thereby causing the water collection channel to generate suction for the residual water in the water receiving channel. When the suction motor assembly generates negative pressure, both the installation space and the suction channel will generate negative pressure, driving the liquid into the sewage tank. Since one end of the water collection channel is connected to the installation space, the negative pressure generated by the suction motor assembly at this time can drive the water collected in the water collection channel to be discharged onto the surface of the roller brush, realizing the recovery and reuse of the liquid remaining in the water receiving channel. Thus, when the water supply assembly and the clean water tank assembly are separated, the occurrence of liquid dripping onto the ground is reduced, keeping the ground clean and tidy, and helping to save water.

[0016] In some embodiments of this disclosure, the water receiving channel includes a first section and a second section. The first section has the connecting port. The water inlet valve is located on the portion of the water receiving channel excluding the first section. The second section is connected to the end of the first section opposite to the connecting port. The cross-sectional area of ​​the second section is smaller than that of the first section. The cross-sectional area of ​​the first section gradually decreases in the direction from the first section to the second section. The water supply assembly includes a sealing element located inside the second section and sealingly fitted to the inner circumferential surface of the second section. The water collection port is disposed opposite to the outer circumferential surface of the sealing element.

[0017] In some embodiments of this disclosure, the water collection channel is provided with an electrically controlled water inlet valve, which is used to open and close the water collection channel. After the base station finishes filling the cleaning equipment with water, when the cleaning equipment is removed from the base station, the electrically controlled water inlet valve is triggered to open for a first predetermined time and then automatically closes. At the same time, the suction motor assembly is temporarily started for a second predetermined time and then closes. Attached Figure Description

[0036] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] In the embodiments of this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] In the description of embodiments of this disclosure, the term "at least one" means one or more, and "more than one" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of a single item or a plurality of items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0039] In the description of embodiments of this disclosure, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this disclosure generally indicates that the preceding and following related objects have an "or" relationship.

[0040] In the description of the embodiments disclosed herein, unless otherwise expressly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0041] As used herein, "perpendicular" and "equal" include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable range of deviation for approximate perpendicularity could be, for example, a deviation within 10°. "Equal" includes absolute equality and approximate equality, where the acceptable range of deviation for approximate equality could be, for example, a difference between the two equalities less than or equal to 10% of either one.

[0042] In related technologies, a cleaning system includes a base station and cleaning equipment. The cleaning equipment is detachably installed on the base station and generally includes a floor brush assembly. The floor brush assembly includes a clean water tank assembly, a floor brush body, and a main body. The main body and the floor brush body are rotatably connected, and the clean water tank assembly is detachably mounted on the floor brush body. The base station has a water supply assembly for replenishing water to the clean water tank assembly. The clean water tank body of the clean water tank assembly has a connection interface for connecting with the water supply assembly, thereby enabling water replenishment to the clean water tank body.

[0043] Currently, there are several ways to connect the water supply component to the clean water tank, such as vertical and horizontal connections. When the water supply component is horizontally connected to the clean water tank, i.e., the interface is located at one end of the clean water tank in the horizontal direction, after the clean water tank is filled with water, when the water supply component and the clean water tank component are separated, residual water will flow out from the interface and drip onto the ground, causing the ground to become damp and dirty. This also leads to water waste and a poor user experience.

[0044] Based on this, in order to solve the above-mentioned technical problems, the cleaning equipment and cleaning system provided in this disclosure utilize a water collection channel to recover residual water in the water receiving channel. One end of the water collection channel has a water inlet for connecting to the water receiving channel, and the other end connects to the installation space. The suction motor assembly is connected to the other end of the suction channel. When the suction motor assembly operates, the suction channel creates negative pressure in the installation space, thereby causing the water collection channel to suction the residual water in the water receiving channel. When the suction motor assembly generates negative pressure, both the installation space and the suction channel generate negative pressure, driving the liquid into the wastewater tank. Since one end of the water collection channel is connected to the installation space, the negative pressure generated by the suction motor assembly can drive the water collected in the water collection channel to be discharged onto the roller brush surface, realizing the recovery and reuse of residual liquid in the water receiving channel. This reduces the occurrence of liquid dripping onto the ground when the water supply assembly and the clean water tank assembly are separated, keeping the ground clean and tidy, and also helps to save water.

[0045] A cleaning system 1000 according to an embodiment of the present disclosure is described below with reference to the accompanying drawings.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, a cleaning system 1000 according to an embodiment of the present disclosure includes a base station 2000 and a cleaning device 100.

[0047] The base station 2000 has a receiving cavity. The cleaning device 100 is detachably installed in the receiving cavity of the base station 2000.

[0048] Specifically, refer to Figure 4 The base station 2000 has a water supply assembly 210. It should be noted that the base station 2000 also has a power unit (such as a liquid pump and / or a fan) for driving the water in the base station 2000 to supply water to the cleaning equipment 100 through the water supply assembly 210.

[0049] The cleaning device 100 according to an embodiment of the present disclosure is described in detail below.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, the cleaning device 100 according to an embodiment of the present disclosure includes: a body (not shown), a floor brush assembly 200, a suction motor assembly (not shown), a wastewater tank (not shown), and a clean water tank assembly 10.

[0051] The floor brush assembly 200 is rotatably connected to the main body. Understandably, Figure 1 , Figure 2 and Figure 3 The cleaning device 100 is shown only schematically, and the actual size, location, and construction of these components are not subject to change. Figure 1 , Figure 2 and Figure 3 And the limitations of the figures below.

[0052] The casing may include a housing (not shown), a control module (not shown), a power supply module (not shown), and a fan (not shown). The housing serves to support internal functional components, such as the control module and power supply module, thus providing good protection for these components. The housing may be made of materials including, but not limited to, metal or plastic.

[0053] For example, the housing can be assembled from multiple shell sections, with adjacent shell sections connected by screws, snap-fits, or other means. This facilitates disassembly of the housing for the maintenance and replacement of internal functional components. Alternatively, the housing can be a single structural unit, resulting in high structural strength.

[0054] The fan is installed inside the housing. The connection between the fan and the housing includes, but is not limited to, adhesive bonding, welding, snap-fitting, or screw connections. The fan includes, but is not limited to, centrifugal fans, axial fans, etc. In other embodiments, the fan may also be installed on the floor brush assembly 200. The fan is used to provide suction for the cleaning equipment 100 to clean the surface being cleaned.

[0055] The control module can be installed inside the housing. The connection methods between the control module and the housing include, but are not limited to, adhesive bonding, welding, snap-fitting, or screw connection. The control module can be electrically connected to the fan for controlling the fan. In other embodiments, the control module can also be installed in the floor brush assembly 200.

[0056] The power supply module is installed inside the housing. The connection methods between the power supply module and the housing include, but are not limited to, adhesive bonding, welding, snap-fitting, or screw connections. The power supply module is used to power the cleaning equipment 100. The power supply module may include, but is not limited to, a battery and a power interface for connecting to a power adapter.

[0057] like Figure 3 and Figure 4As shown, the floor brush assembly 200 includes: a floor brush body 20 and a roller brush 30.

[0058] The suction motor assembly is located inside the machine body, which forms a negative pressure channel. The floor brush assembly 200 is rotatably connected to the machine body. A wastewater tank is located in the machine body or the floor brush body 20, and the wastewater tank has a wastewater chamber. The wastewater chamber is connected to both the negative pressure channel and the suction channel 203 (described below). The suction motor assembly can be a fan, etc. The suction motor assembly generates negative pressure, which draws wastewater from the installation space 201 (described below) into the wastewater chamber through the negative pressure channel and the suction channel 203, thus achieving wastewater collection.

[0059] For example, the wastewater tank is detachably mounted on the body or brush body 20. This facilitates the removal of the wastewater tank for the discharge and cleaning of the wastewater. The detachable connection between the wastewater tank and the body or brush body 20 includes, but is not limited to, screw connections and snap-fit ​​connections.

[0060] The suction channel 203 is connected to the negative pressure channel through the sewage chamber; or, the suction channel 203 is connected to the negative pressure channel through at least a part of the sewage chamber. When the sewage tank is located on the machine body, the suction channel 203 is connected to the negative pressure channel through at least a part of the sewage chamber. When the sewage tank is located on the floor brush body 20, the suction channel 203 is connected to the negative pressure channel through the sewage chamber.

[0061] Specifically, refer to Figure 4 and Figure 13 As shown, the clean water tank assembly 10 includes a clean water tank body 1, which has a water inlet channel 11, a water storage chamber 12, and a water collection channel 13.

[0062] The water inlet channel 11 provides a channel for injecting water into the water storage chamber 12. One end of the water inlet channel 11 is provided with a connection port 113 for connecting to an external water supply, and the other end is provided with a water inlet valve 4 for connecting to the water storage chamber 12. (See reference...) Figure 4 The water supply assembly 210 is at least partially detachable within the water inlet channel 11. The water supply assembly 210 extends into the water inlet channel 11 from the connector 113, allowing the water inlet of the water supply assembly 210 to be closer to the inlet valve 4, thus facilitating the replenishment of water to the water storage chamber 12 and reducing leakage of liquid from the connector 113. The inlet valve 4 enables the water supply assembly 210 to replenish water to the water storage chamber 12, and after replenishment, the inlet valve 4 prevents water from flowing out of the water storage chamber 12.

[0063] For further information, please refer to [link / reference]. Figure 4 As shown, the water collection channel 13 is used to recover the residual water in the water receiving channel 11. One end of the water collection channel 13 is provided with a water collection port 131 for connecting to the water receiving channel 11, and the other end is used to connect to the installation space 201.

[0064] Understandably, since one end of the water collection channel 13 is provided with a water collection port 131 for connecting to the water receiving channel 11, when the water supply component 210 and the clean water tank component 10 are separated, the liquid remaining in the water receiving channel 11 can flow into the water collection channel 13 through the water collection port 131 to realize the recovery of liquid. Thus, when the water supply component 210 and the clean water tank component 10 are separated, the occurrence of liquid dripping on the ground is reduced, the ground is kept clean and tidy, and it is also conducive to saving water.

[0065] Further, please refer to Figure 4 , Figure 5 and Figure 6 As shown, the cleaning device 100 also includes a pump assembly connected to the water storage chamber 12, which supplies water to the floor brush assembly 200. The water storage chamber 12 has an outlet valve 111 located at its lower end. The pump assembly drives the liquid in the water storage chamber 12 to be discharged through the outlet valve 111. It is understood that after being discharged from the outlet valve 111, the liquid can flow to the roller brush 30, wetting it and thus cleaning the floor. Since the water collection channel 13 and the water storage chamber 12 are separated, the operation of the pump assembly does not affect the liquid flow within the water collection channel 13.

[0066] Further, please refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the floor brush body 20 has an installation space 201 and a suction channel 203, with the bottom of the installation space 201 open; the installation space 201 is connected to one end of the suction channel 203. It should be noted that the floor brush body 20 is located at the lower end of the main body and is rotatably connected to the lower end of the main body. The materials of the floor brush body 20 include, but are not limited to, metal, plastic, and a combination of both.

[0067] The suction motor assembly is connected to the other end of the suction channel 203. When the suction motor assembly is working, the suction channel 203 creates a negative pressure in the installation space 201, which in turn causes the water collection channel 13 to generate suction for the residual water in the water collection channel 11.

[0068] It is understandable that when the suction motor assembly generates negative pressure, both the installation space 201 and the suction channel 203 will generate negative pressure, driving the liquid into the sewage tank. Since one end of the water collection channel 13 is connected to the installation space 201, the negative pressure generated by the suction motor assembly can drive the water collected in the water collection channel 13 to be discharged onto the surface of the roller brush 30, realizing the recycling and reuse of the liquid remaining in the water receiving channel 11. Thus, when the water supply assembly 210 is separated from the clean water tank assembly 10, the occurrence of liquid dripping onto the ground is reduced, keeping the ground clean and tidy, and is conducive to saving water.

[0069] Further, please refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the roller brush 30 is rotatably disposed within the installation space 201. The rotation center line of the roller brush 30 extends in the left-right direction, which facilitates the roller brush 30 to roll in the front-back direction to clean the surface to be cleaned.

[0070] Further, please refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the clean water tank assembly 10 is detachably mounted on the floor brush body 20, thereby facilitating the disassembly, cleaning, and maintenance of the clean water tank assembly 10 and the floor brush body 20.

[0071] According to the embodiments of the present disclosure, the floor brush assembly 200 uses a water collection channel 13 to recover residual water in the water receiving channel 11. One end of the water collection channel 13 is provided with a water inlet 131 for connecting to the water receiving channel 11, and the other end is used to connect to the installation space 201. The suction motor assembly is connected to the other end of the suction channel 203. When the suction motor assembly is working, the installation space 201 is generated by the suction channel 203, thereby causing the water collection channel 13 to generate suction for the residual water in the water receiving channel 11. When the suction motor assembly generates negative pressure, both the installation space 201 and the suction channel 203 will generate negative pressure, driving the liquid into the sewage tank. Since one end of the water collection channel 13 is connected to the installation space 201, the negative pressure generated by the suction motor assembly can drive the water collected in the water collection channel 13 to be discharged onto the surface of the roller brush 30, realizing the recycling and reuse of the liquid remaining in the water receiving channel 11. Thus, when the water supply assembly 210 is separated from the clean water tank assembly 10, the occurrence of liquid dripping onto the ground is reduced, keeping the ground clean and tidy, and also helping to save water.

[0072] Please refer to some embodiments of this disclosure. Figure 4 and Figure 13 As shown, the device body is equipped with a grip for the user to hold and push. The clean water tank body 1 is mounted on the floor brush assembly 200. The water receiving channel 11 extends along the pushing direction of the cleaning device 100 to facilitate connection with the water supply terminal (such as the water supply assembly 210) on the base station 2000 after being pushed into the base station 2000. It should be noted that the forward pushing direction when the device body is facing the floor brush assembly 200 is generally directly in front of the floor brush assembly.

[0073] This facilitates the connection between the interface 113 of the clean water tank assembly 10 and the water inlet. For example, when the storage cavity of the base station 2000 is open at one end in the horizontal direction to form an inlet and outlet, and the forward pushing direction of the device facing the ground brush assembly 200 is also horizontal (or approximately horizontal), the cleaning device 100 moves horizontally through the inlet and outlet to enter and exit the base station. When the water inlet is located at one end of the water supply assembly 200 in the horizontal direction, it is convenient for the interface 113 to be plugged into the water inlet to supply water to the cleaning device 100. In other embodiments, the storage cavity may also be open at the top and closed on the sides, and the cleaning device 100 can be manually stored into the storage cavity from top to bottom.

[0074] In some embodiments of this disclosure, see Figure 4 One end of the water inlet channel 11 is provided with a docking interface 113 for connecting to the water supply component 210, and the other end is provided with a water inlet valve 4 for connecting to the water storage chamber 12. After the water supply component 210 is connected to the water inlet channel 11, the water collection port 131 and the water inlet valve 4 are separated by the water supply component 210.

[0075] Its other end is provided with an inlet valve 4 for connecting the water storage chamber 12; after the water supply component 210 is connected to the water receiving channel 11, the water collection port 131 and the inlet valve 4 are separated by the water supply component 210. At this time, the water injected into the inlet valve 4 from the water supply component 210 cannot connect with the water collection port 131, that is, the water collection port 131 is covered or separated. At this time, it is isolated from the channel where water is flowing. Only when the water supply component 210 is connected to or separated from the water receiving channel 11 can the water collection port 131 truly play the role of recycling the residual water in the water receiving channel 11.

[0076] See Figure 4 The water supply assembly 210 is at least partially detachable within the water inlet channel 11. The water supply assembly 210 extends into the water inlet channel 11 from the connector 113, allowing the water inlet of the water supply assembly 210 to be closer to the inlet valve 4, thus facilitating the replenishment of water to the water storage chamber 12 and reducing leakage of liquid from the connector 113. The inlet valve 4 enables the water supply assembly 210 to replenish water to the water storage chamber 12, and after replenishment, the inlet valve 4 prevents water from flowing out of the water storage chamber 12.

[0077] Please refer to some embodiments of this disclosure. Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a drainage channel 204 is provided at one end of the water collection channel 13. The outlet of the drainage channel 204 is located on the inner wall of the installation space 201. The vertical projection of the roller brush 30 on the plane where the outlet of the drainage channel 204 is located overlaps with the outlet of the drainage channel 204.

[0078] This design facilitates the recycling of water falling into the drain channel onto the roller brush, allowing water flowing from the drain channel 204 outlet to directly act on the roller brush 30. This ensures the roller brush 30 is fully wetted during cleaning, thereby improving cleaning effectiveness. Simultaneously, this layout optimizes the water flow path, reducing water waste and making the entire cleaning process more efficient and environmentally friendly. In practical applications, this design significantly improves the performance and user experience of the cleaning equipment 100.

[0079] Furthermore, the drainage channel 204 is formed on the brush body 20, so that the wall of the drainage channel 204 and the brush body 20 are integrally molded, which makes the internal structure well sealed and reduces the leakage of liquid inside.

[0080] Alternatively, the drainage channel 204 can be formed within a drainage pipe independent of the brush body 20. This reduces modifications to the internal structure of the brush body 20, and the drainage pipe can be adapted to the internal spatial layout of the brush body 20 (length, bending direction, etc.), thus facilitating manufacturing. Furthermore, when the drainage channel 204 is formed within a drainage pipe independent of the brush body 20, the brush body 20 and the clean water tank body 1 need to have openings (not shown in the figure) to avoid the drainage pipe, and the drainage pipe must be sealed to these openings to prevent water leakage.

[0081] The inlet of drainage channel 204 is directly connected to water collection channel 13, and the outlet of drainage channel 204 is either directly connected to installation space 201. It should be noted that "directly connected to installation space 201" means that there are no other channels between the outlet of drainage channel 204 and installation space 201. This ensures smooth liquid flow and reduces the possibility of liquid leakage inside the brush body 20.

[0082] Please refer to some embodiments of this disclosure. Figure 4 and Figure 13 As shown, the clean water tank body 1 is mounted on the floor brush assembly 200, and the water receiving channel 11 extends along the forward pushing direction of the cleaning device 100. It should be noted that the forward pushing direction when the machine body is facing the floor brush assembly 200 is generally the front of the floor brush assembly.

[0083] This facilitates the connection between the interface 113 of the clean water tank assembly 10 and the water inlet. For example, when the storage cavity of the base station 2000 is open at one end in the horizontal direction to form an inlet and outlet, and the forward pushing direction of the device facing the ground brush assembly 200 is also horizontal (or approximately horizontal), the cleaning device 100 moves horizontally through the inlet and outlet to enter and exit the base station. When the water inlet is located at one end of the water supply assembly 200 in the horizontal direction, it is convenient for the interface 113 to be plugged into the water inlet to supply water to the cleaning device 100. In other embodiments, the storage cavity may also be open at the top and closed on the sides, and the cleaning device 100 can be manually stored into the storage cavity from top to bottom.

[0084] In some embodiments of this disclosure, please refer to Figure 7 and Figure 8 As shown, the floor brush assembly 200 also includes a scraper 205. In the pushing direction of the cleaning device 100, the scraper 205 is located within the installation space 201, on the side of the installation space 201 opposite to the suction channel 203. The outlet of the drainage channel 204 is located on the scraper 205. This arrangement allows the liquid flowing from the outlet of the drainage channel 204 to fully and evenly wet the roller brush 30 under the action of the scraper 205, thereby improving the cleaning effect of the roller brush 30 on the floor and making the cleaning work more efficient and thorough. At the same time, this structural design also avoids liquid waste, allowing the liquid to be precisely applied to the areas that need cleaning.

[0085] In some embodiments of this disclosure, please refer to Figure 9 and Figure 10 As shown, the outlet of the drainage channel 204 is located directly above the suction channel 203. This makes the outlet of the drainage channel 204 closer to the suction channel 203, resulting in greater suction force, thereby improving the adsorption efficiency of liquid in the water collection channel 13 and increasing the recycling rate of liquid remaining in the water receiving channel 11.

[0086] Further, please refer to Figure 9 and Figure 10 As shown, when the outlet of the drainage channel 204 is directly connected to the suction channel 203, the vertical projection of the roller brush 30 on the plane where the inlet of the drainage channel 204 is located overlaps with the inlet of the drainage channel 204. This facilitates the discharge of liquid flowing out of the outlet of the drainage channel 204 onto the roller brush 30 as much as possible, reduces the probability that the liquid flowing out of the outlet of the drainage channel 204 will be directly sucked into the suction channel 203, and improves the recycling rate of liquid remaining in the water receiving channel 11.

[0087] In some embodiments of this disclosure, the water collection channel 13 is located below the water receiving channel 11, and the bottom wall of the water collection channel 13 extends downward along the direction from the water inlet 131 to the inlet of the drainage channel 204.

[0088] Understandably, by extending the bottom wall of the water collection channel 13 downwards along the direction from the inlet 131 to the inlet of the drainage channel 204, the flow rate of liquid within the water collection channel 13 can be accelerated. When liquid enters the water collection channel 13 from the inlet 131, due to the inclination of the bottom wall, the liquid can flow more smoothly towards the inlet of the drainage channel 204 under its own gravity, reducing the residence time of the liquid within the water collection channel 13 and allowing the liquid to reach the drainage channel 204 more quickly. Simultaneously, this inclined design effectively prevents liquid accumulation within the water collection channel 13, preventing bacterial growth and odor problems caused by liquid residue, ensuring the hygiene of the cleaning equipment 100, extending the equipment's service life, and providing users with a higher quality and healthier cleaning experience.

[0089] Please refer to some embodiments of this disclosure. Figure 11 , Figure 12 and Figure 13 As shown, the water receiving channel 11 includes a first section 114 and a second section 115. The first section 114 has a connecting port 113. A water inlet valve 4 is located on the portion of the water receiving channel 11 excluding the first section 114. The second section 115 is connected to the end of the first section 114 opposite to the connecting port 113. The cross-sectional area of ​​the second section 115 is smaller than that of the first section 114. From the first section 114 to the second section 115, the cross-sectional area of ​​the first section 114 gradually decreases. It should be noted that when the water receiving channel 11 only includes the first section 114 and the second section 115, the water inlet valve 4 is located on the end of the second section 115 opposite to the first section 114.

[0090] Understandably, in the direction from the first segment 114 to the second segment 115, the cross-sectional area of ​​the first segment 114 gradually decreases, thus forming a guiding structure and improving the fault tolerance when the water supply assembly 210 and the clean water tank assembly 10 are connected, which is beneficial for the smooth connection of the water supply assembly 210 and the clean water tank assembly 10. The cross-sectional area of ​​the second segment 115 is smaller than that of the first segment 114, which facilitates a sealing between the inner circumferential wall of the water supply assembly 210 and the clean water tank assembly 10 when they are connected, thereby reducing liquid leakage when the water supply assembly 210 supplies water to the water storage chamber 12.

[0091] For some embodiments of this disclosure, please refer back to the previous section. Figure 4 and combined Figure 11 , Figure 12 and Figure 13As shown, when the water inlet channel 11 includes a first section 114 and a second section 115, the water supply assembly 210 includes a seal 220. The seal 220 is located inside the second section 115 and is sealed and fitted to the inner circumferential surface of the second section 115. The water inlet 131 is disposed opposite to the outer circumferential surface of the seal 220.

[0092] Understandably, the water inlet 131 and the outer peripheral surface of the seal 220 are positioned opposite each other. This allows the water inlet 131 to be sealed by the seal 220 when the water supply assembly 210 injects water into the water storage chamber 12. This prevents water from flowing from the water inlet 131 into the water collection channel 13 and filling the water collection channel 13, thus preventing the collection of liquid remaining in the water receiving channel 11. Therefore, by positioning the water inlet 131 and the outer peripheral surface of the seal 220 opposite each other, it is beneficial to recycle and reuse liquid remaining in the water receiving channel 11. This reduces the occurrence of liquid dripping onto the ground when the water supply assembly 210 and the connector 113 are separated, keeping the ground clean and tidy, and also helps to save water.

[0093] In some embodiments of this disclosure, please refer to Figure 14 and Figure 15 As shown, the clean water tank body 1 has an exhaust port 17, which is connected to the water storage chamber 12. The clean water tank assembly 10 also includes an air vent valve 3. The air vent valve 3 is movably disposed at the exhaust port 17 along the axial direction of the exhaust port 17. The air vent valve 3 is unidirectionally open from the inside of the water storage chamber 12 to the outside of the water storage chamber 12.

[0094] Understandably, when the water supply assembly 210 supplies water to the water storage chamber 12, the internal air pressure of the water storage chamber 12 increases, the air outlet valve 3 opens, and the gas in the water storage chamber 12 flows out from the inside to the outside of the water storage chamber 12, thereby preventing the internal air pressure of the water storage chamber 12 from becoming too high and maintaining the internal air pressure of the water storage chamber 12 stable. When the water storage chamber 12 supplies water to the roller brush, external gas can flow into the water storage chamber 12 through the water collection channel 13 and the water receiving channel 11, thereby maintaining the internal air pressure of the water storage chamber 12 stable.

[0095] For further information, please refer to [link / reference]. Figure 15As shown, the vent valve 3 includes a head 31 and a main body 32. The head 31 is located outside the water storage chamber 12 and covers the vent 17. The main body 32 passes through the vent 17. When the water storage chamber 12 supplies water to the roller brush, a negative pressure is generated inside the water storage chamber 12. The head 31 will abut against the surface of the clean water tank body 1, thereby preventing the entry of external gas. When the water supply assembly 210 supplies water to the water storage chamber 12, a positive pressure is generated in the water storage chamber 12. The vent valve 3 moves away from the inside of the water storage chamber 12, thereby separating the head 31 from the surface of the clean water tank body 1. The gas in the water storage chamber 12 is discharged through the gap between the main body 32 and the peripheral wall of the vent 17, thereby realizing unidirectional gas flow from the inside of the water storage chamber 12 to the outside of the water storage chamber 12.

[0096] In some embodiments of this disclosure, please refer to Figure 16 and Figure 17 As shown, the end of the second segment 115 away from the first segment 114 is provided with an abutment 14, and the water inlet valve 4 is located on the side of the abutment 14 away from the first segment 114. The end of the abutment 14 facing the first segment 114 is provided with a trigger protrusion 142, and the water collection port 131 is located on the side of the trigger protrusion 142 facing the first segment 114. The trigger protrusion 142 can be a cylinder or a triangular prism, etc.

[0097] Understandably, please combine Figure 4 And see Figure 16 and Figure 17 As shown, the water supply assembly 210 includes a water supply body 211, a trigger head 212, and an elastic member 213. The water supply body 211 has a water inlet (not shown in the figure). The trigger head 212 is movable along the axial direction of the water inlet and is used to open or close the water inlet. The elastic member 213 is connected to the trigger head 212 and is used to drive the trigger head 212 to move in the direction of closing the water inlet. The trigger head 212 is adapted to abut against the trigger protrusion 142 to move in the direction of opening the water inlet.

[0098] Therefore, when the trigger head 212 comes into contact with the trigger protrusion 142, the trigger head 212 moves in the direction of opening the water inlet, thereby opening the water inlet to supply water to the water storage chamber 12. When the clean water tank assembly 10 separates from the base station 20, the trigger head 212 moves and resets in the direction of closing the water inlet under the action of the elastic element 213, thereby blocking the water inlet and stopping the water supply assembly 210 from supplying water. The opening and closing of the water inlet are both achieved through physical mechanical means, without the need for additional electrical components, thus simplifying the structure and saving costs.

[0099] In some embodiments of this disclosure, please refer to Figure 16 and Figure 17As shown, the abutment member 14 includes: a plurality of ribs 141, the plurality of ribs 141 extending in different directions and intersecting at the junction 143, the plurality of ribs 141 defining a plurality of sub-ports, the plurality of sub-ports allowing water to flow to the water inlet valve 4, and the trigger protrusion 142 being provided at the junction 143.

[0100] Understandably, the multiple reinforcing ribs 141 are spaced apart along the circumferential direction of the water receiving channel 11, and the arrangement of the multiple reinforcing ribs 141 improves the structural strength of the abutment member 14. For example, in Figure 11 In the example shown, there are 4 ribs 141 and 4 sub-holes, but this disclosure is not limited to this. The number of ribs 141 and sub-holes can also be other numbers, such as 2, 5, 6 or 7.

[0101] Please refer to Figure 16 and Figure 17 As shown, the abutment member 14 further includes an annular rib 144. One end of each of the plurality of ribs 141 facing away from the confluence portion 143 is connected to the annular rib 144, forming a plurality of openings between the annular rib and the plurality of ribs 141. This further enhances the structural strength of the abutment member 14. However, this disclosure is not limited to this; it is also possible that one end of each of the plurality of ribs 141 facing away from the confluence portion 143 is directly connected to the inner peripheral wall of the water receiving channel 11.

[0102] In some embodiments of this disclosure, please refer to Figure 16 and Figure 17 As shown, the water collection port 131 is located in the first section 114. It can be understood that the water collection port 131 is located in the first section 114, which makes the water collection port 131 closer to the outside of the clean water tank body 1. This is conducive to better collection of residual liquid in the water receiving channel 11, and better realization of liquid recycling and reuse in the water receiving channel 11. This reduces the occurrence of liquid dripping onto the ground when the water supply component 210 and the clean water tank component 10 are separated, keeps the ground clean and tidy, and helps to save water.

[0103] For some embodiments of this disclosure, please refer back to the previous section. Figure 12 and Figure 13 As shown, the clean water tank body 1 includes: a tank body 15, a bottom plate 16 and a sealing ring. The tank body 15 has a water storage chamber 12 and a water receiving channel 11. The tank body 15 has a collection chamber (not shown in the figure), and the collection chamber has a water collection port 131. The bottom of the collection chamber is open, forming an open opening (not shown in the figure). The bottom plate 16 is detachably provided at the open opening, and the bottom plate 16 and the inner wall of the collection chamber together form a water collection channel 13.

[0104] Understandably, the base plate 16 is detachably located at the open end, which facilitates timely cleaning and maintenance of the water collection channel 13 and reduces dirt residue in the water collection channel 13.

[0105] Furthermore, a sealing ring is disposed between the base plate 16 and the housing 15 to seal the opening. This prevents liquid in the water collection channel 13 from leaking from the opening, improving the sealing performance. The sealing ring can be disposed between the inner peripheral wall of the opening and the outer peripheral wall of the base plate 16, or it can be disposed on the outer periphery of the base plate 16 and abut against the surface of the housing 15 with the opening.

[0106] Please refer to some embodiments of this disclosure. Figure 12 and Figure 13 As shown, the inlet valve 4 includes a valve body 42, a valve core 43, and a reset member 5. The valve core 43 is movably located within the valve body 42 along its axial direction. The reset member 5 is used to drive the valve core 43 to move toward the interface 113. The valve body 42 can be integrally formed with the inner wall of the water inlet channel 11.

[0107] Understandably, in practical applications, when the water supply assembly 210 supplies water to the water storage chamber 12, as the water pressure rises, it overcomes the driving force of the reset member 5, driving the valve core 43 to move away from the interface 113, thereby opening the inlet valve 4 and enabling the water supply assembly 210 to supply water to the water storage chamber 12. When the water dispensing operation is completed, the water supply assembly 210 stops supplying water to the water storage chamber 12, and the water pressure drops. The reset member 5, relying on its own elasticity or other ability to recover deformation, will continue to drive the valve core 43 to move towards the interface 113 until the inlet valve 4 is closed again, effectively preventing water leakage from the water storage chamber 12 through the inlet valve 4, ensuring the normal use and sealing of the clean water tank assembly 10. At the same time, the reset member 5 also makes the opening and closing of the inlet valve 4 more convenient and reliable, improving the overall performance of the clean water tank assembly 10.

[0108] For example, the reset member 5 can be a spring. In other embodiments, both the reset member 5 and the valve core 43 can be magnetic components. When the valve core 43 is located between the reset member 5 and the interface 113, there can be a magnetic repulsion between the reset member 5 and the water inlet valve 4. When the reset member 5 is located between the valve core 43 and the interface 113, there can be a magnetic attraction between the reset member 5 and the water inlet valve 4.

[0109] For further information, please refer to [link / reference]. Figure 12 and Figure 13As shown, the valve body 42 has an installation channel, which is part of the water inlet channel and communicates with the interface 113. At least a portion of the reset member 5 is movably disposed in the installation channel. The installation channel includes a first channel 421 and a second channel 422. The second channel 422 is disposed on the side of the first channel 421 opposite to the interface 113 and communicates with the first channel 421. The cross-sectional area of ​​the second channel 422 is larger than that of the first channel 421. The valve core 43 has a stop portion 41. The outer peripheral wall of the stop portion 41 is adapted to stop and seal with the inner peripheral wall of the first channel 421.

[0110] Therefore, when the valve core 43 moves away from the interface 113, the stop part 41 moves away from the first channel 421, and the outer peripheral wall of the stop part 41 is separated from the inner peripheral wall of the second channel 422, thereby opening the water inlet valve 4, allowing water to flow from the water inlet channel 11 to the water storage chamber 12. When the valve core 43 moves towards the interface 113, the stop part 41 returns to the first channel 421, thereby achieving a stop seal between the outer peripheral wall of the stop part 41 and the inner peripheral wall of the first channel 421, thereby closing the water inlet valve 4, effectively preventing water in the water storage chamber 12 from leaking from the water inlet valve 4, and ensuring the normal use and sealing of the clean water tank assembly 10.

[0111] In some embodiments of this disclosure, an electrically controlled water inlet valve (not shown) is provided in the water collection channel 13. The electrically controlled water inlet valve is used to open and close the water collection channel 13. After the base station 2000 finishes filling the cleaning equipment with water, when the cleaning equipment is removed from the base station 2000, the electrically controlled water inlet valve is triggered to open for a first predetermined time and then automatically closes. At the same time, the suction motor assembly is temporarily started for a second predetermined time and then closes.

[0112] Understandably, when the base station 2000 finishes filling the cleaning equipment with water and the cleaning equipment is removed from the base station 2000, the electronically controlled water inlet valve is triggered to open, so that the water in the water collection channel 13 can be discharged. At this time, the suction motor assembly is temporarily started, thereby accelerating the discharge of water in the water collection channel 13.

[0113] Therefore, after the cleaning equipment has added water to the base station 2000, the water in the water collection channel 13 can be rapidly discharged through the operation of the suction motor assembly, regardless of whether the cleaning equipment is cleaning the ground. This design ensures that residual water in the water collection channel 13 can be discharged promptly when the cleaning equipment leaves the base station, preventing residual water from spilling onto the ground or the base station and affecting user experience. Once the residual water in the water collection channel 13 and the water inlet channel 11 is discharged promptly, the electrically controlled water inlet valve is closed. When the cleaning equipment 100 is cleaning the ground normally, the suction power of the suction motor assembly does not need to be allocated to the water collection channel 13 for residual water suction; it can be used entirely for ground cleaning.

[0114] The first and second predetermined times can be set according to actual needs to achieve optimal drainage and equipment protection. The opening and closing of the electrically controlled inlet valve is precisely controlled by the control system to ensure the stability and reliability of the entire process.

[0115] In the description of this specification, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples without contradicting each other.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
