Description

Technical Field

[0001] This utility model relates to the field of cleaning, specifically to a floor cleaning device. Background Technology

[0002] Existing floor cleaning devices, such as mops and scrubbers, typically have wastewater and clean water tanks installed in different locations on the main body of the device. Regarding the installation or removal structure of the wastewater tank, when the wastewater is emptied during use, dirt adhering to the wastewater inlet on the tank can easily fall onto the main body where it is installed. This can lead to improper reinstallation of the wastewater tank, causing wastewater to overflow from the wastewater inlet between the tank and the main body, severely impacting the user experience. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the aforementioned related technologies.

[0004] Therefore, the purpose of this utility model is to provide a ground cleaning device, which mainly solves the problem of sewage overflow between the sewage tank and the main body of the existing ground cleaning device.

[0005] The present invention provides a floor cleaning device, including a device body, a receiving cavity provided on the device body, and a receiving part provided on the receiving cavity;

[0006] It also includes a cleaning component, which is configured to be placed on the receiving cavity and the receiving part is formed to provide a supporting placement structure for the cleaning component;

[0007] The cleaning component is equipped with a clean water tank and a wastewater tank. The wastewater tank has a wastewater cavity inside and a placement cavity outside the wastewater cavity. The clean water tank is placed on the placement cavity.

[0008] The sewage tank is also equipped with a spray nozzle for spraying and cleaning the side walls of the sewage chamber. The clean water tank is equipped with a water supply channel, which is connected to the spray nozzle to supply clean water to the spray nozzle.

[0009] The bottom end face of the cleaning component is provided with a clean water outlet and a sewage inlet, and the receiving part is provided with a clean water inlet and a sewage outlet. When the cleaning component is installed in place on the receiving cavity, the clean water inlet and the clean water outlet are in contact and connected, and the sewage outlet and the sewage inlet are in contact and connected.

[0010] The sewage outlet is positioned below the clean water inlet, so that when there is clean water on the receiving part, the clean water flows towards the sewage outlet, thereby forming a cleaning structure for the bottom end face of the receiving part and the sewage outlet.

[0011] The aforementioned floor cleaning device has a recessed receiving section, with a wastewater outlet located at the rear end of the bottom end face of the receiving section and a clean water inlet located at the front end of the bottom end face of the receiving section. The bottom end face of the receiving section is arranged to gradually slope downward from front to back to guide the clean water to flow towards the wastewater outlet on the bottom end face of the receiving section.

[0012] The aforementioned floor cleaning device has an upward-protruding actuating part on the receiving part. When a part of the cleaning component is located in the receiving part and the cleaning component is not installed in the receiving cavity, the actuating part is configured to open the clean water outlet. This causes the clean water in the clean water tank to flow downward to the bottom end face of the receiving part and flow towards the sewage outlet, thereby forming a structure for cleaning the bottom end face of the receiving part and the sewage outlet.

[0013] The aforementioned floor cleaning device is configured such that when a portion of the cleaning component is located within the receiving part and the cleaning component is not fully installed on the receiving cavity, a gap distance H is formed between the clean water outlet and the bottom end face of the receiving part. The gap distance H is set to be less than or equal to the maximum recess depth of the receiving part, and the protrusion height of the triggering part is set to be greater than the maximum recess depth of the receiving part, so that the clean water outlet and the bottom end face of the receiving part are interconnected under the structure of the gap distance H.

[0014] The aforementioned floor cleaning device is equipped with a connection structure that seals the clean water inlet and outlet when the cleaning components are installed in the accommodating cavity, and a connection structure that seals the sewage outlet and inlet, so that the clean water inlet, clean water outlet, sewage inlet and sewage outlet are all disconnected from the receiving part.

[0015] The aforementioned ground cleaning device has a sewage inlet channel inside the sewage tank. The sewage inlet channel is configured with a through structure, with the upper opening of the sewage inlet channel connected to the sewage chamber. A spray nozzle is located above the upper opening of the sewage inlet channel and below the airflow port on the sewage tank.

[0016] The aforementioned floor cleaning device has a placement part on the placement cavity, and the placement part has a through-hole in the vertical direction. When the clean water tank is placed on the placement cavity, the placement part is configured to support the clean water tank and to limit a portion of the clean water tank by placing it inside the through-hole. The clean water outlet is located inside the through-hole or below the through-hole.

[0017] The aforementioned floor cleaning device has a spray section on the side wall of the sewage chamber that has a ring-shaped structure in the circumferential direction of the sewage chamber. The spray section is configured to be recessed towards the outside of the sewage chamber, and a spray nozzle is provided on the spray section to form a structure in which clean water can flow from the spray nozzle into the spray section, thereby forming a structure in which clean water performs ring-shaped rinsing and cleaning on the side wall of the sewage chamber.

[0018] The aforementioned floor cleaning device has a front-opening accommodating cavity with a cleaning component detachably placed on the accommodating cavity, and a front-opening placement cavity with a clean water tank detachably placed inside the placement cavity.

[0019] The aforementioned floor cleaning device has a sewage outlet connected to the sewage chamber on the bottom or side end face of the sewage tank. A cover is provided on the outside of the sewage outlet to form an opening and closing structure for the sewage outlet.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this solution, the clean water tank and the wastewater tank are configured as a cleaning and cleaning component. The cleaning and cleaning component can be independently installed on or removed from the main body of the device, which is convenient for users. Users do not need to install or disassemble the clean water tank and the wastewater tank separately. The cleaning and cleaning component can be installed or removed as an independent part, which improves the ease of operation for users.

[0022] In this solution, the cleaning component and the main body of the device form a structure that allows for cleaning of the bottom end face of the receiving part. This enables the timely removal of residual dirt and grime from the bottom end face of the receiving part during the installation of the cleaning component, thus keeping the receiving part between the cleaning component and the main body of the device clean. This improves the reliability and stability of the installation of the cleaning component and reduces the likelihood of sewage leakage.

[0023] In this solution, the structure for cleaning the bottom end face of the receiving part allows for the effective use of the cleaning components during installation into the accommodating cavity to supply clean water from the water tank for cleaning the receiving part. This eliminates the need for the user to separately provide clean water for cleaning the receiving part, greatly improving the convenience of cleaning the receiving part.

[0024] In this solution, the structure of the receiving part allows clean water to flow and clean the bottom end face of the receiving part, as well as the sewage outlet. This effectively cleans the bottom end face of the receiving part and the sewage outlet, improving the stability and reliability of the cleaning components when they are installed.

[0025] In this solution, the cleaning structure of the receiving part allows the wastewater after cleaning to flow into the wastewater outlet in a timely manner and be collected into the wastewater tank when the ground cleaning device is working. Wastewater or dirt is not easily left on the receiving part, so that the receiving part can be effectively kept clean.

[0026] The structure in this solution that cleans the bottom surface of the receiving part ensures that clean water from the water tank is generated each time the cleaning component is installed. This cleans the bottom surface of the receiving part, flushing away any remaining dirt and grime and flushing it into the wastewater outlet. This ensures that no dirt remains on the bottom surface of the receiving part, allowing the cleaning component to be installed stably and reliably. It also prevents wastewater or clean water from overflowing between the cleaning component and the receiving part, thus improving the user experience of using the floor cleaning device.

[0027] This solution also includes a structure for cleaning the inner wall of the sewage chamber, so that clean water from the clean water tank can be effectively supplied to the sewage chamber to form a spray cleaning effect on the side wall of the sewage chamber, so that users do not need to clean the sewage chamber separately.

[0028] In this solution, the structure of the spray nozzle and spray section forms a circumferential spray cleaning effect on the side wall of the sewage chamber in the circumferential direction, effectively reducing the blind area of ​​spray cleaning and effectively cleaning the side wall of the sewage chamber in the circumferential direction.

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] Example: The floor cleaning device of this utility model, such as Figures 1 to 3 As shown in the configuration, the ground cleaning device mainly includes a cleaning component 2. The cleaning component 2 can be installed on or removed from the device body 1 as a whole, which is convenient for users. At the same time, by setting a cleaning structure for the receiving part 1011 on the device body 1, the problem of sewage overflow between the sewage tank 202 and the device body 1 in existing ground cleaning devices can be effectively solved, and the stability and reliability of the cleaning component 2 in docking with the device body 1 can be improved.

[0035] The ground cleaning device of this solution includes a main body 1, on which a receiving cavity 101 is provided, and a receiving part 1011 is provided on the receiving cavity 101; it also includes a cleaning component 2, which is positioned on the receiving cavity 101 and the receiving part 1011 forms a supporting structure for the cleaning component 2; the user can place the cleaning component 2 into the receiving cavity 101, at which time the receiving part 1011 forms a supporting structure for the cleaning component 2, so that the cleaning component 2 is stably placed in the receiving cavity 101. The cleaning component 2 is mainly used to provide clean water and collect and hold wastewater. Specifically, the cleaning component 2 is provided with a clean water tank 201 and a wastewater tank 202. The clean water tank 201 holds clean water and supplies it for mopping during the floor cleaning process. The wastewater tank 202 collects and holds wastewater, allowing the floor cleaning device to collect the wastewater during the cleaning process. The wastewater tank 202 has a wastewater chamber 2022 inside and a placement chamber on the outside of the wastewater chamber 2022. The clean water tank 201 is placed on the placement chamber. This allows the clean water tank 201 and the wastewater tank 202 to form an independent component, namely the cleaning component 2. Treating the cleaning component 2 as an independent component makes it convenient for users to install or disassemble it, improving the ease of operation.

[0036] This solution also includes a structure for cleaning the sewage tank 202. Specifically, a spray nozzle 2024 is provided on the sewage tank 202 to spray and clean the side wall of the sewage chamber 2022. A water supply channel is provided on the clean water tank 201, and the water supply channel is connected to the spray nozzle 2024 to supply clean water to the spray nozzle 2024. The spray nozzle 2024 is located on the side wall of the sewage tank 202 and is connected to the sewage chamber 2022. One end of the water supply channel is connected to the clean water chamber in the clean water tank 201, and the other end is connected to the spray nozzle 2024. This allows clean water from the clean water tank 201 to be supplied to the spray nozzle 2024, which then sprays clean water onto the side wall of the sewage chamber 2022 to achieve a cleaning effect. This eliminates the need for users to use external clean water to clean the sewage chamber 2022 separately.

[0037] Optionally, a water pump is also installed on the clean water tank 201. The water pump works to supply clean water to the spray nozzle 2024 through the water supply channel to achieve the cleaning effect on the side wall of the sewage chamber 2022.

[0038] In this design, a clean water outlet 2011 and a wastewater inlet 2021 are provided on the bottom end face of the cleaning component 2. A clean water inlet 10111 and a wastewater outlet 10112 are provided on the receiving part 1011. The clean water outlet 2011 is used for the clean water in the clean water tank 201 to flow outward. The clean water inlet 10111 is used for the clean water in the clean water tank 201 to flow out through the clean water outlet 2011 and then into the clean water inlet 10111 to supply clean water to the outside of the clean water tank 201. The wastewater outlet 10112 is used for the flow of wastewater collected on the ground. The wastewater inlet 2021 is used for the collected wastewater to flow into the wastewater outlet 10112. The wastewater enters the sewage inlet 2021 and then enters the sewage tank 202 for collection and storage. When the cleaning component 2 is installed in place on the receiving cavity 101, the clean water inlet 10111 and the clean water outlet 2011 are in contact and connected, and the sewage outlet 10112 and the sewage inlet 2021 are in contact and connected. At this time, the cleaning component 2 is fully installed, so that the clean water in the clean water tank 201 can be supplied to the outside through the clean water outlet 2011 and the clean water inlet 10111 in sequence, so that the sewage and garbage on the ground can be sucked up and moved in sequence through the sewage outlet 10112 and the sewage inlet 2021 and collected into the sewage tank 202.

[0039] The wastewater outlet 10112 is positioned below the clean water inlet 10111. This configuration allows clean water to flow towards the wastewater outlet 10112 when there is clean water on the receiving part 1011, thus cleaning the bottom surface of the receiving part 1011 and the wastewater outlet 10112. Since the clean water inlet 10111 is higher than the wastewater outlet 10112, dirt or debris on the receiving part 1011 is less likely to adhere to or enter the clean water inlet 10111. When clean water cleans the bottom surface of the receiving part 1011 or the wastewater outlet 10112, the resulting clean water... Water does not easily enter the clean water inlet 10111. Instead, it forms wastewater that flows towards the wastewater outlet 10112 and eventually enters the wastewater outlet 10112. This ensures that the clean water not only cleans the bottom end face of the receiving part 1011 and the wastewater outlet 10112, but also that the wastewater generated during the cleaning process enters the wastewater outlet 10112, keeping the bottom end face of the receiving part 1011 and the wastewater outlet 10112 clean. This allows the cleaning component 2 to be stably installed when it is in place, preventing the overflow of wastewater or clean water between the cleaning component 2 and the receiving part 1011.

[0040] In this solution, the wastewater generated during the cleaning of the bottom end face of the receiving part 1011 and the wastewater outlet 10112 can flow back and forth to the ground or back to the roller along the wastewater pipe inside the ground cleaning device after entering the wastewater outlet 10112. When the roller rotates and rolls to clean the ground, and when the ground cleaning device is working, the backflowing wastewater can be sucked up and collected into the wastewater tank 202. Alternatively, a buffer part can be set up in the wastewater pipe inside the ground cleaning device. After the wastewater flows back, it will be temporarily collected in the buffer part. When the ground cleaning device starts to clean the ground, the wastewater in the buffer part can be sucked up and collected into the wastewater tank 202.

[0041] In this design, to further enhance the cleaning effect of clean water on the receiving part 1011, the receiving part 1011 is configured as a concave structure. A wastewater outlet 10112 is located at the rear end of the bottom end face of the receiving part 1011, and a clean water inlet 10111 is located at the front end of the bottom end face of the receiving part 1011. Furthermore, the bottom end face of the receiving part 1011 is designed to gradually slope downwards from front to back, thus guiding the clean water to flow towards the wastewater outlet 10112 on the bottom end face of the receiving part. This inclined structure ensures that when clean water enters the receiving part... After the receiving part 1011, clean water flows along the inclined structure, effectively cleaning the dirt and grime remaining on the receiving part 1011. The dirt and grime flow together with the clean water toward the sewage outlet 10112, ultimately allowing the clean water to carry the dirt and grime into the sewage outlet 10112, keeping the receiving part 1011 and the sewage outlet 10112 clean. This ensures that when the cleaning component 2 is installed, it can be stably connected, preventing the overflow of sewage or clean water between the cleaning component 2 and the receiving part 1011.

[0042] The specific structural part for supplying clean water from the clean water tank 201 to the receiving part 1011 includes an upwardly protruding actuating part 10113 on the receiving part 1011. This actuating part 10113 is configured to open the clean water outlet 2011 when a portion of the cleaning component 2 is located within the receiving part 1011 but not yet fully installed on the receiving cavity 101. This allows the clean water in the clean water tank 201 to flow downwards to the bottom surface of the receiving part 1011 and towards the wastewater outlet 10112, thus providing a flow cleaning effect on the bottom surface of the receiving part 1011 and the wastewater outlet 10112. During the installation of the cleaning component 2 into the receiving cavity 101, when a portion of the cleaning component 2 enters the receiving part 1011, the actuating part 10113 gradually moves into the clean water tank 201. The clean water outlet 2011 is opened, and the clean water in the clean water tank 201 flows downward into the receiving part 1011 to clean the receiving part 1011. At the same time, the clean water flows and cleans the bottom end face of the receiving part 1011 towards the sewage outlet 10112. In the process of cleaning the receiving part 1011, the sewage outlet 10112 is also cleaned, thereby cleaning the dirt and grime on the bottom end face of the receiving part 1011 and the sewage outlet 10112, keeping the receiving part 1011 and the sewage outlet 10112 clean. This ensures that when the cleaning component 2 is installed in place, it can be stably connected and installed, and it is not easy for sewage or clean water to overflow between the cleaning component 2 and the receiving part 1011.

[0043] Specifically, for the structural portion where a part of the cleaning component 2 is located within the receiving portion 1011 and the cleaning component 2 is not fully installed, a gap distance H is formed between the clean water outlet 2011 and the bottom end face of the receiving portion 1011 when a part of the cleaning component 2 is located within the receiving portion 1011 and the cleaning component 2 is not fully installed on the receiving cavity 101. At this time, the clean water outlet 2011 on the cleaning component 2 and the bottom end face of the receiving portion 1011 are vertically spaced apart. The gap distance H is set to be less than or equal to the maximum recess depth of the receiving portion 1011 so that a part of the cleaning component 2 is located within the recessed structure of the receiving portion 1011. Furthermore, the protrusion height of the actuating portion 10113 is set to be greater than the maximum recess depth of the receiving portion 1011 so that the upward protrusion height of the actuating portion 10113 enters the clean water outlet 2011 of the cleaning component 2, thereby... The structure allows the clean water outlet 2011 and the bottom end face of the receiving part 1011 to be interconnected with each other by a distance H. When the trigger part 10113 enters the clean water outlet 2011, the clean water outlet 2011 is opened. At this time, the clean water in the clean water tank 201 flows downward through the clean water outlet 2011 and enters the recessed structure of the receiving part 1011, achieving a cleaning effect on the bottom end face of the receiving part 1011. This also creates a cleaning effect on the sewage outlet 10112 after the clean water flows and cleans the bottom end face of the receiving part 1011. This allows the receiving part 1011 to be cleaned and kept in a clean state before the cleaning component 2 is installed in place. This ensures that when the cleaning component 2 is installed in place, a stable docking installation can be formed, making it less likely for sewage or clean water to overflow between the cleaning component 2 and the receiving part 1011.

[0044] Optionally, a buffer section is provided in the receiving part 1011. The buffer section forms a relatively slight interference structure with a part of the cleaning component 2. When the user installs the cleaning component 2 into the receiving cavity 101, the cleaning component 2 will pause for a certain period of time due to the interference structure of the buffer section. At this time, the user needs to apply more external force to continue to install the cleaning component 2 into place and achieve complete installation of the cleaning component 2. During the pause of the cleaning component 2, the clean water in the clean water tank 201 will enter the receiving part 1011 to achieve the cleaning effect on the bottom end face of the receiving part 1011 and the sewage outlet 10112, thereby achieving a better cleaning effect.

[0045] A sealing cover is installed inside the clean water outlet 2011 on the clean water tank 201. The sealing cover is connected to a spring, allowing it to move vertically. During the installation of the cleaning component 2, when the actuating part 10113 contacts the sealing cover, it pushes the sealing cover upward, moving it away from the clean water outlet 2011 and opening the clean water outlet 2011. When the cleaning component 2 is not fully installed, the clean water outlet 2011 opens, allowing some clean water to flow into the recessed structure of the receiving part 1011, thus cleaning the bottom end face of the receiving part 1011 and the wastewater outlet 10112. This prevents dirt and debris from remaining on the bottom end face of the receiving part 1011 during the installation or removal of the cleaning component 2. When the cleaning component 2 is installed, improper installation may cause water leakage. When the cleaning component 2 is fully installed, the clean water outlet 2011 and the clean water inlet 10111 are in contact and connected to form a structure in which the clean water tank 201 supplies clean water to the clean water inlet 10111, ultimately achieving the cleaning effect of supplying clean water to the ground or roller. When the cleaning component 2 is disassembled, it moves away from the receiving cavity 101, away from the receiving part 1011 and the touching part 10113. At this time, the sealing cover is reset under the action of the spring and moves closer to the clean water outlet 2011. When the touching part 10113 is no longer in contact with the sealing cover, the sealing cover closes the clean water outlet 2011, preventing water leakage from the clean water outlet 2011.

[0046] Understandably, when there is dirt or other debris remaining on the bottom end face of the receiving part 1011, although the clean water component can be forcibly installed in place, it is easy to cause gaps between the sewage inlet 2021 and the sewage outlet 10112, and between the clean water inlet 10111 and the clean water outlet 2011, which can easily lead to the overflow of sewage and clean water. This can cause the floor cleaning device to leak sewage during use, which can easily cause secondary pollution to the ground and result in a poor user experience.

[0047] In this design, when the cleaning component 2 is installed in the accommodating cavity 101, a sealing connection structure is established between the clean water inlet 10111 and the clean water outlet 2011, and a sealing connection structure is established between the wastewater outlet 10112 and the wastewater inlet 2021. Simultaneously, at this time, the clean water inlet 10111, clean water outlet 2011, wastewater inlet 2021, and wastewater outlet 10112 are all disconnected from the receiving part 1011; that is, when the cleaning component 2 is installed in the accommodating cavity 101, the cleaning component 2... When a portion of the cleaning component 2 is located within the receiving section 1011 and is not fully installed, the clean water tank 201 can supply clean water to the receiving section 1011 to clean the bottom surface of the receiving section 1011 and the wastewater outlet 10112. When the cleaning component 2 is fully installed, the clean water tank 201 cannot supply clean water to the receiving section 1011 for cleaning; instead, it supplies clean water to the clean water inlet 10111 to provide the clean water needed for the floor cleaning device during the floor cleaning process. In this case, The sewage outlet 10112 and sewage inlet 2021 are in contact with each other to form a sealed connection structure for the flow of sewage, enabling the floor cleaning device to collect and treat sewage on the ground during operation. The clean water inlet 10111 and clean water outlet 2011 are in contact with each other to form a sealed connection structure for the clean water tank 201 to supply clean water to meet the cleaning needs of the floor cleaning device. At this time, the floor cleaning device can perform the cleaning effect normally. At the same time, the receiving part 1011 is not connected to the clean water inlet 10111, clean water outlet 2011, sewage inlet 2021 and sewage outlet 10112. At this time, neither sewage nor clean water will overflow into the receiving part 1011. The sealed connection structure allows the receiving part 1011 to be stably used for docking and installation with the cleaning component 2, so that the cleaning component 2 is stably placed in the receiving cavity 101 and is not easy to shake or tip over, and the problem of sewage and clean water overflow is not likely to occur.

[0048] To further improve the cleaning effect on the sidewalls of the sewage chamber 2022, this solution includes a sewage inlet channel 2023 inside the sewage tank 202. The sewage inlet channel 2023 allows sewage to flow into the sewage chamber 2022. It connects to the sewage outlet 10112 on the main body 1 of the device. The sewage inlet channel 2023 is designed with a through-hole structure, with its upper opening connected to the sewage chamber 2022. The lower opening of the sewage inlet channel 2023 forms a sewage inlet 2021. Sewage enters the sewage channel within the ground cleaning device, moves to the sewage outlet 10112, and then enters the sewage inlet channel 2023 through the sewage inlet 2021, finally flowing into the sewage chamber 2022. The system collects and treats wastewater and garbage during the operation of the ground cleaning device. A spray nozzle 2024 is positioned above the upper opening of the wastewater inlet channel 2023 and below the airflow inlet 2026 on the wastewater tank 202. This reduces blind spots in cleaning the side walls of the wastewater chamber 2022, primarily in the vertical direction. The water flowing downwards through the spray nozzle 2024 effectively cleans a large area of ​​the side walls of the wastewater chamber 2022. The water also flows downwards from below the airflow inlet 2026, rinsing the area where wastewater enters the wastewater chamber 2022 from the upper opening of the wastewater inlet channel 2023 and its vicinity. This effectively reduces blind spots in cleaning the side walls of the wastewater chamber 2022.

[0049] Optionally, for the structure of the ground cleaning device for collecting sewage, an air outlet 2026 is provided on the sewage tank 202. The air outlet 2026 is connected to the fan on the main body 1 of the device so that the suction force of the airflow generated when the fan is working can be used to collect sewage, so that the sewage on the ground is collected into the sewage tank 202.

[0050] In this design, for the structural part where the clean water tank 201 is placed on the wastewater tank 202, a placement part is provided on the placement cavity to support and place the clean water tank 201. The placement part also has a through-hole in the vertical direction, located at the end face of the placement part. When the clean water tank 201 is placed on the placement cavity, the placement part forms a supporting structure for the clean water tank 201, and a portion of the clean water tank 201 is located within the through-hole, thus forming a confined structure. The clean water outlet 2011 is located within the through-hole or below it. A protruding part can be provided on the clean water tank 201. The protrusion enters the passage to form a limiting structure between the protrusion and the passage, thereby limiting the lower end of the clean water tank 201 within the passage. This prevents the clean water tank 201 from shaking or tipping over when installed on the sewage tank 202. At the same time, a clean water outlet 2011 can be provided on the end face of the protrusion, so that the clean water outlet 2011 is located inside or below the passage. This facilitates a more stable connection between the clean water outlet 2011 and the trigger part 10113 or the clean water inlet 10111 on the receiving part 1011, so that clean water can be better supplied into the receiving part 1011 or the clean water inlet 10111.

[0051] To further improve the automatic cleaning effect of the sewage chamber 2022, this solution includes a spray section 2025 with a ring-shaped structure in the circumferential direction on the side wall of the sewage chamber 2022. The spray section 2025 is designed as a recessed structure facing outwards from the sewage chamber 2022, and a spray nozzle 2024 is located on the spray section 2025 to allow clean water to flow into the spray section 2025. This creates a structure where clean water performs a ring-shaped rinsing and cleaning of the side wall of the sewage chamber 2022. The spray section 2025 is a ring-shaped recessed structure in the ring direction, and the spray nozzle 2024 sprays... When clean water enters the recessed structure of the spray section 2025, it flows in a circular direction. Eventually, the clean water forms a complete ring, and when the recessed structure is filled with clean water, it overflows. At this time, the overflowing clean water flows downward along the side wall of the sewage chamber 2022, achieving a comprehensive cleaning effect on the side wall of the sewage chamber 2022. This effectively reduces blind spots in cleaning the side wall of the sewage chamber 2022. The clean water flows downward in a complete ring direction to clean the side wall of the sewage chamber 2022. The cleaned sewage is collected at the bottom of the sewage chamber 2022, and then the user can discharge the sewage in the sewage chamber 2022.

[0052] In order to prevent secondary pollution of the cleaned sidewalls of the sewage chamber 2022 when the user discharges the sewage, a sewage discharge structure can be installed at the bottom or side of the sewage chamber 2022 to discharge the sewage. This eliminates the need to tip over the sewage tank 202 to discharge the sewage, and thus prevents secondary pollution of the cleaned sidewalls of the sewage chamber 2022 when the sewage is discharged.

[0053] Optionally, the spray section 2025 is configured to be open towards the middle of the sewage chamber 2022, so that when the clean water overflows after the spray section 2025 is full, it flows along the open structure to achieve the cleaning effect on the side wall of the sewage chamber 2022.

[0054] The clean water tank 201 is equipped with a water pump, which is connected to a water supply channel. One end of the water supply channel is connected to the clean water chamber inside the clean water tank 201, and the other end is connected to the spray nozzle 2024. When the cleaning component 2 is installed, the power module inside the main body 1 supplies power to the water pump. The control module can control the water pump to allow the clean water in the clean water chamber to enter the spray nozzle 2024 through the water supply channel. The clean water is then sprayed onto the side wall of the sewage chamber 2022 through the spray nozzle 2024 to achieve the cleaning effect on the side wall of the sewage chamber 2022. Alternatively, the clean water can be moved through the spray nozzle 2024 to the annular recessed structure of the spray section 2025 to spray and clean the four sides of the sewage chamber 2022 in the circumferential direction. This achieves the effect of automatically cleaning the side wall of the sewage chamber 2022 using the clean water in the clean water tank 201.

[0055] In this solution, for the structural part on the main body 1 where the cleaning component 2 is installed, the receiving cavity 101 can be configured as a front-open structure, and the cleaning component 2 can be detachably placed in the receiving cavity 101. The receiving cavity 101 is configured as a front-open recessed structure, allowing the cleaning component 2 to be placed into the receiving cavity 101 through the open structure. Simultaneously, a snap-fit ​​limiting structure, such as a snap-fit ​​structure or a spring-loaded structure, is provided between the receiving cavity 101 and the cleaning component 2 to achieve detachable installation of the cleaning component 2. When component 2 is installed in place, the cleaning component 2 is locked and engaged within the receiving cavity 101. When it is necessary to remove the cleaning component 2, the user only needs to apply external force to activate the locking and engaging structure to separate the cleaning component 2 from the receiving cavity 101, thus enabling the removal of the cleaning component 2. The detachable installation structure of the cleaning component 2 facilitates user maintenance, such as adding clean water to the clean water tank 201 and emptying the wastewater tank 202 for sewage discharge, making it convenient for users to operate.

[0056] In this solution, regarding the structural part where the clean water tank 201 is installed on the wastewater tank 202, the placement cavity can be designed to be open at the front, allowing the clean water tank 201 to be detachably placed within it. The placement cavity is designed as a recessed structure with an open front, allowing the clean water tank 201 to be placed into it through the open structure. Simultaneously, a locking and limiting structure, such as a snap-fit ​​or spring-loaded structure, is provided between the placement cavity and the clean water tank 201 to achieve detachable installation of the clean water tank 201. When the clean water tank 201 is installed in place, it is locked and limited within the placement cavity. When it is necessary to remove the clean water tank 201, only external force from the user is required to engage the locking and limiting structure. The positioning structure triggers the separation between the clean water tank 201 and the placement chamber, enabling the disassembly of the clean water tank 201. The clean water tank 201 is designed for detachable installation, facilitating user maintenance. For example, when adding clean water to the clean water tank 201, it can be disassembled separately from the wastewater tank 202 for individual maintenance. Similarly, when adding clean water to the wastewater tank 201 without needing to empty it, the wastewater tank 202 in the cleaning assembly 2 can be installed while the clean water tank 201 can be independently disassembled.

[0057] In this solution, to improve the convenience of discharging sewage from the sewage tank 202 and to prevent secondary pollution of the sidewalls of the sewage chamber 2022 during discharge, a drain outlet connected to the sewage chamber 2022 can be provided on the bottom or side end face of the sewage tank 202. Sewage from the sewage chamber 2022 can be discharged through the drain outlet. A cover is provided on the outside of the drain outlet, which serves as the opening and closing structure for the drain outlet. The cover can be manually put on or removed from the drain outlet by the user to achieve the opening or closing structure of the drain outlet. When it is necessary to discharge sewage from the sewage chamber 2022, the user can manually remove the cover to open the drain outlet and discharge the sewage. When the sewage is discharged, the user can install the cover on the drain outlet to close the drain outlet. At this time, the sewage tank 202 can be used normally to collect sewage, thus facilitating the user to discharge the sewage from the sewage tank 202.

[0058] In this solution, one approach is that when the user discharges sewage from the sewage chamber 2022 through the drain port without removing the cleaning component 2, the system can control the supply of clean water from the clean water tank 201 to the spray nozzle 2024 to clean the side walls of the sewage chamber 2022. This allows for simultaneous sewage discharge and cleaning of the sewage chamber 2022, simplifying user operation and eliminating the need for separate cleaning of the sewage chamber 2022. Another approach is that when the user removes the cleaning component 2 to discharge sewage, the system can reinstall the cleaning component 2 after discharge and activate the system to supply clean water from the clean water tank 201 to the spray nozzle 2024 to clean the side walls of the sewage chamber 2022. After cleaning, the user can then discharge the sewage from the sewage chamber 2022, achieving automatic cleaning of the sewage chamber 2022. This simplifies user operation and eliminates the need for separate external water supply for cleaning the sewage chamber 2022, significantly improving the user experience.

[0059] In this solution, if the user discharges the sewage in the sewage chamber 2022 without removing the cleaning component 2, the sewage can be discharged directly into the indoor sewer through the drain outlet. Alternatively, a sewage discharge component can be installed to connect the drain outlet and the indoor sewer, so that the sewage in the sewage chamber 2022 can be discharged without removing the cleaning component 2.

[0060] The floor cleaning device in this solution can be mainly configured as a handheld mop or a handheld scrubber. It uses a clean water tank 201 to supply clean water to achieve the cleaning effect on the floor, and a wastewater tank 202 to collect the wastewater generated during the cleaning process, thus achieving the cleaning effect on the floor through the floor cleaning device.

[0061] In this solution, the ground cleaning device also includes a cleaning body, which is connected to the device body 1. The device body 1 can drive the cleaning body to move on the ground to achieve the cleaning effect. The cleaning body is equipped with rollers, drive structure, etc. The device body 1 is also equipped with a power module, suction module, etc. The suction module is used to suck up and collect sewage and dirt into the sewage tank 202. These are all existing technologies and will not be described in detail here. They can be set up according to existing technologies.

[0062] For any aspects not covered in this solution, existing technologies can be used or referenced.

[0063] Working Principle: This floor cleaning device uses a cleaning component 2 to facilitate the installation and removal of the clean water tank 201 and the wastewater tank 202. The clean water tank 201 of the cleaning component 2 provides clean water, and the wastewater tank 202 collects wastewater. The device body 1 includes a housing cavity 101 for installing the cleaning component 2, a receiving part 1011, and other structures. The receiving part 1011 is designed for cleaning. During the installation of the cleaning component 2, the clean water outlet 2011 of the clean water tank 201 can be opened. Clean water is supplied to the receiving part 1011 to clean the bottom end face of the receiving part 1011. This can clean the dirt on the receiving part 1011 in a timely manner, so as to improve the effective connection between the cleaning component 2 and the receiving part 1011. This improves the reliability of the contact and sealing connection between the clean water inlet 10111 and the clean water outlet 2011, and the sewage inlet 2021 and the sewage outlet 10112. It is not easy for sewage or clean water to overflow, not easy to cause leakage, and thus not easy to cause secondary pollution to the ground, which greatly improves the user experience.
