Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a floor scrubber. Background Technology

[0002] As people have higher and higher requirements for home cleaning, convenient cleaning tools such as household floor scrubbers are becoming more and more popular. Vacuum cleaners, floor scrubbers and other convenient tools were born under this trend.

[0003] Currently, most floor scrubbers on the market consist of a main unit and a base station. During operation, the scrubber uses a fan to suck dirt into a wastewater tank, then uses a roller brush to clean the floor. It is then returned to the base station for self-cleaning and charging. In contrast, most vacuum cleaners on the market require users to hold the machine and vacuum point-to-point, and most do not have a water suction function.

[0004] Because floor scrubbers and vacuum cleaners differ significantly in their usage scenarios, most households have a high demand for both, using floor scrubbers to clean floors and vacuum cleaners to clean crevices in furniture. However, with current multi-functional floor scrubbers on the market, switching from scrubbing mode to vacuuming mode requires users to manually disassemble the fan and install the corresponding vacuuming accessories. This process is not only time-consuming but also involves numerous unnecessary steps, significantly impacting the user experience and reducing ease of operation and efficiency. Furthermore, frequent disassembly and assembly increases the risk of user errors, potentially leading to equipment damage or performance degradation.

[0005] Therefore, existing technologies still need further development. Summary of the Invention

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0032] Please see Figures 1 to 5 As shown in the embodiment of the present invention, the present invention provides a floor scrubber, including: a body 1, a floor brush structure 2, a wastewater tank 3, a dust collection box 4, and a suction structure 5. The floor brush structure 2 is disposed below the body 1; the wastewater tank 3 is disposed on the body 1, and the first storage chamber 30 of the wastewater tank 3 is connected to the suction port 20 of the floor brush structure 2; the dust collection box 4 is disposed on the body 1, and the wastewater tank 3 and the dust collection box 4 are spaced apart; the suction structure 5 is movably disposed on the body 1, and the suction port 50 of the suction structure 5 is connected to the second storage chamber 40 of the dust collection box 4; wherein, when the floor scrubber is in the floor scrubbing mode, dirt on the ground is sucked into the first storage chamber 30 through the suction port 20 of the floor brush structure 2; when the floor scrubber is in the suction mode, dust is sucked into the second storage chamber 40 through the suction port 50 of the suction structure 5.

[0033] As can be seen, the floor scrubber provided by the present invention includes a body 1, a floor brush structure 2, a wastewater tank 3, a dust collection box 4, and a suction structure 5. The floor brush structure 2 is installed below the body 1 and is rotatably arranged relative to the body 1. The wastewater tank 3 and the dust collection box 4 are spaced apart on the body 1. The wastewater tank 3 has a first storage chamber 30 for storing dirt (i.e., floor dirt), and the dust collection box 4 has a second storage chamber 40 for storing dust particles. The suction structure 5 is movably arranged on the body 1 and has a suction port 50 communicating with the second storage chamber 40. When the user needs to vacuum, the floor scrubber executes a vacuuming mode according to the user's instructions, so that dust particles are sucked into the second storage chamber 40 of the dust collection box 4 through the suction port 50. When the user needs to wash the floor, the floor scrubber executes a washing mode according to the user's instructions, cleaning the floor through at least part of the movement of the floor brush structure 2, and the floor dirt is sucked into the first storage chamber 30 of the wastewater tank 3 through the suction port 20 of the floor brush structure 2. By integrating both the floor brush structure 2 and the vacuuming structure 5 onto the machine body, the floor scrubber can simultaneously perform both scrubbing and vacuuming functions. This allows users to switch between different cleaning modes without manually replacing or disassembling any parts, simplifying operation, reducing complexity, and improving convenience and flexibility. This design not only provides users with an efficient and convenient cleaning experience but also ensures the continuity and efficiency of the cleaning process, significantly reducing cleaning time and improving work efficiency, enabling users to complete cleaning tasks faster. Simultaneously, by independently setting up the wastewater tank and dust collection box, wastewater and dust are treated separately, effectively avoiding cross-contamination and maintaining hygiene during the cleaning process. Furthermore, the combined design of the floor brush structure 2 and the vacuuming structure 5 effectively handles liquid dirt and dust, improving cleaning results. In summary, the floor scrubber of this invention not only improves ease of use but also demonstrates higher efficiency and effectiveness in dirt handling, meeting the diverse needs of modern users for cleaning equipment and effectively solving the technical problem of requiring component replacement when switching between scrubbing and vacuuming functions in existing multi-functional floor scrubbers.

[0034] Ground dirt usually refers to any dirt, sewage or pollutants that adhere to the ground surface.

[0035] Furthermore, at least a portion of the suction structure 5 is located above the body 1. In addition to a suction mode and a floor cleaning mode, the floor scrubber also has a floor cleaning and suction mode.

[0036] The floor cleaning and vacuuming mode refers to the ability of the floor scrubber to perform both vacuuming and floor cleaning tasks simultaneously during the same operation. In this mode, while vacuuming is performed by the vacuuming structure 5, the floor brush structure 2 can also perform floor cleaning.

[0037] When the floor scrubber is in scrubbing mode, it only performs scrubbing operations, cleaning the floor using the floor brush structure 2. When the floor scrubber is in vacuuming mode, it only performs vacuuming operations, sucking dust and debris into the second storage chamber 40 through the vacuum port 50.

[0038] Furthermore, the body 1 is provided with a second receiving recess and a third receiving recess at intervals, the sewage tank 3 is detachably disposed in the second receiving recess, and the dust collection box 4 is detachably disposed in the third receiving recess.

[0039] Optionally, the wastewater tank 3 and the dust collection box 4 are arranged opposite each other.

[0040] like Figure 3 and Figure 4 As shown, the floor scrubber also includes a first fan 6 and a second fan 7. The first fan 6 is mounted on the body 1; the air intake of the first fan 6 is connected to the first storage chamber 30; the second fan 7 is mounted on the body 1, and its first connecting channel is connected to the suction port 50 of the suction structure 5 and the second storage chamber 40, respectively. With this structure, by setting the first fan 6 and the second fan 7, the two fans can be started and operated separately as needed during floor scrubbing or vacuuming operations. Furthermore, the independent operation of the first fan 6 and the second fan 7 achieves dry-wet separation of wastewater and dust, avoiding secondary pollution problems caused by mixed storage. Moreover, by having two fans handle different cleaning tasks, the floor scrubber can complete both vacuuming and floor scrubbing simultaneously, significantly improving cleaning efficiency. In addition, the independent operation of the first fan 6 and the second fan 7 ensures that each fan operates at its optimal performance, providing stronger suction and a more thorough cleaning effect. In conclusion, the dual-fan configuration ensures the stability and reliability of the floor scrubber when performing complex cleaning tasks, thereby improving the user experience.

[0041] Furthermore, the first blower 6 is located above the wastewater tank 3, and the second blower 7 is located above the dust collection box, with the suction port 50 connected to the second storage chamber 40 of the dust collection box 4 via the first connecting channel of the second blower 7. When the second blower 7 is started, dust particles enter the first connecting channel and the second storage chamber 40 of the second blower 7 sequentially through the suction port 50.

[0042] Optionally, the first fan 6 is disposed inside the body 1, and the body 1 is provided with a fourth receiving recess, which is located above the third receiving recess and is connected to the third receiving recess. The second fan 7 is installed inside the fourth receiving recess.

[0043] Specifically, the floor scrubber also includes a control structure connected to the first fan 6 and the second fan 7, respectively. The control structure controls the start and stop of the first fan 6 and / or the second fan 7. When the control structure starts the first fan 6 and the second fan 7, the floor scrubber is in scrubbing and vacuuming mode. This structural arrangement, by setting up the control structure and starting the first fan 6 and / or the second fan 7, allows the user to choose to start a single fan or both fans according to actual needs, thus providing a more flexible cleaning solution. Furthermore, when the control structure starts the first fan 6 and the second fan 7 simultaneously, the floor scrubber can perform both vacuuming and scrubbing tasks in the same operation, significantly improving cleaning efficiency. The control structure can also automatically adjust the operating status of each fan according to user commands, further enhancing the user experience and the intelligence level of the equipment.

[0044] Specifically, such as Figures 1 to 4 As shown, the vacuuming structure 5 includes: a gripping component 51 and a vacuuming pipe 52. The gripping component 51 is detachably mounted on the body 1 and has a vacuum port 50. A first vacuuming channel 56 is provided inside the gripping component 51, which communicates with the vacuum port 50. The vacuuming pipe 52 is retractably mounted inside the body 1 and is connected to the dust collection box 4 and the gripping component 51 respectively. The vacuuming pipe 52 has a second vacuuming channel 520, which communicates with the second storage chamber 40 and the first vacuuming channel 56 respectively. When the floor scrubber is performing vacuuming operations, the gripping component 51 is separated from the body 1, and the vacuuming pipe 52 is in an extended state. This structural design, with the grip component 51, provides a comfortable grip and reduces fatigue during prolonged use. Furthermore, the grip component 51 is detachably mounted on the body 1, allowing users to easily separate or install it according to their cleaning needs, thus improving operational flexibility and convenience. Simultaneously, the retractable suction pipe 52 provides users with a wider operating range, enabling them to easily clean hard-to-reach areas such as under furniture and corners.

[0045] Furthermore, the end of the suction pipe 52 away from the gripping component 51 is connected to the second fan 7, and the second suction channel 520 is connected to the second storage chamber 40 through the first connecting channel of the second fan 7.

[0046] Optionally, the gripping component 51 is detachably inserted into the body 1.

[0047] Optionally, when the floor scrubber is in scrubbing mode, the gripping part 51 is inserted into the body 1 for scrubbing by hand by holding the gripping part 51.

[0048] Furthermore, such as Figure 2As shown, a first groove 100 is provided on the top of the body 1, which forms a grip part that is convenient for the user to hold. When the floor scrubber is in the floor scrubbing and vacuuming mode, the user separates the grip part 51 from the body 1. The user can use one hand to hold the grip part 51 to vacuum, and can also use one hand to hold the grip part to move the floor brush structure 2 to scrub the floor.

[0049] Specifically, such as Figure 2 As shown, the vacuuming structure 5 also includes a first vacuuming button 53 and a second vacuuming button 54, which are spaced apart on the grip component 51. When the user presses the first vacuuming button 53 or the second vacuuming button 54, the floor scrubber performs vacuuming operations. This structural arrangement, with the first vacuuming button 53 and the second vacuuming button 54 spaced apart on the grip component 51, allows the user to easily operate the machine according to their hand position.

[0050] Furthermore, the control structure is connected to the first vacuum button 53 and the second vacuum button 54 respectively. The user can send a vacuuming command to the control structure through the first vacuum button 53 or the second vacuum button 54 so that the control structure can control the second fan 7 to start.

[0051] Optionally, when the user separates the holding part 51 from the body 1, the floor scrubber automatically switches to vacuuming standby mode (i.e., in this mode, the floor scrubber is ready to perform vacuuming operations), and when the user presses the first vacuuming button 53 or the second vacuuming button 54, the floor scrubber directly performs vacuuming operations.

[0052] Specifically, such as Figures 1 to 4As shown, the gripping component 51 includes a gripping member 511 and a connecting member 512. The gripping member 511 is for a user to hold. A first vacuum button 53 and a vacuum port 50 are spaced apart on the gripping member 511. The gripping member 511 has a first flow channel 561 extending along a first preset trajectory. One end of the connecting member 512 is connected to the gripping member 511, and the other end of the connecting member 512 is detachably connected to the body 1. The end of the vacuum pipe 52 away from the dust collection box 4 is inserted into the other end of the connecting member 512. A second vacuum button 54 is disposed on the connecting member 512. The connecting member 512 has a second flow channel 562 extending along a second preset trajectory. The first flow channel 561 communicates with both the vacuum port 50 and the second flow channel 562. The end of the second flow channel 562 away from the first flow channel 561 communicates with the second vacuum channel 520. The first flow channel 561 and the second flow channel 562 form a first vacuum channel 56. This structural design, with the connector 512 and the grip 511 detachably mounted on the body 1 via the connector 512, extends the length of the grip 511, thereby improving operational flexibility. This allows the floor scrubber to adapt to different cleaning scenarios, reduces the frequency of bending over, and enhances the user experience. Simultaneously, the connector 512 facilitates cleaning dust and debris in narrow, deep areas. Furthermore, placing the first vacuum button 53 on the grip 511 and the second vacuum button 54 on the connector 512 allows users to adjust their grip according to different cleaning needs, and also allows them to select the most convenient button based on their hand position. This design fully considers user habits and comfort, making operation more flexible and convenient.

[0053] Specifically, such as Figures 1 to 4 As shown, the dust collection structure 5 also includes: a dust guide tube 55, one end of which is connected to the grip member 51, and the other end of which extends away from the grip member 51; the dust guide tube 55 has a suction port 50, a dust guide port 550, and a dust guide channel 551 that communicates with both the suction port 50 and the dust guide port 550; the suction port 50 is located at the end of the dust guide tube 55 away from the grip member 51, and the dust guide port 550 is located at the end of the dust guide tube 55 close to the grip member 51, and the dust guide port 550 communicates with the first suction channel 56. With this structural arrangement, the dust guide tube 55 can guide dust particles, allowing them to pass through the dust guide tube 55 from the suction port 50 along the dust guide channel 551 into the first suction channel 56, thereby allowing the dust particles to enter the second storage chamber 40 of the dust collection box 4 along the first suction channel 56.

[0054] Optionally, the dust guide tube 55 is mounted on the grip 511 and protrudes from the grip 511. The dust guide tube 55 is located on the outer arcuate surface of the grip 511, and the dust guide port 550 is connected to the first flow channel 561.

[0055] Optionally, when the second fan 7 is running, the high rotation of the second fan 7 creates a negative pressure in the second storage chamber 40, thereby causing dust and debris to be drawn into the suction port 50 along with the outside air, and then sequentially enter the second storage chamber 40 of the dust collection box 4 through the first suction channel 56, the second suction channel 520, the air inlet of the second fan 7, and the first connecting channel of the second fan 7.

[0056] Specifically, such as Figure 4 and Figure 5 As shown, the floor scrubber also includes: an exhaust pipe 8, which is installed inside the machine body 1; the exhaust pipe 8 is connected to the wastewater tank 3 and the dust collection box 4 respectively; the exhaust pipe 8 has an exhaust channel 80, which is connected to the first storage chamber 30 and the second storage chamber 40 respectively; wherein, when the floor scrubber is in the vacuuming mode, the air entering the second storage chamber 40 enters the first storage chamber 30 through the exhaust channel 80. With this structural arrangement, by setting the exhaust pipe 8, the air entering the second storage chamber 40 can be introduced into the first storage chamber 30 of the wastewater tank 3 through the exhaust pipe 8 in the vacuuming mode, thereby blowing away moisture and drying the solid waste in the first storage chamber 30, thus preventing the growth of bacteria and odors.

[0057] Meanwhile, in the floor cleaning and vacuuming mode, the first storage chamber 30 is connected to the second storage chamber 40 through the exhaust channel 80. Under the joint operation of the first fan 6 and the second fan 7, the negative pressure in the first storage chamber 30 is increased, thereby improving the suction power of the floor scrubber and thus improving the overall cleaning ability.

[0058] Specifically, such as Figure 4 and Figure 5As shown, the exhaust pipe 8 has a first air inlet 81 and a first air outlet 82 connected to the exhaust channel 80. The first air inlet 81 is located in the second storage chamber 40, and the first air outlet 82 is located on the wastewater tank 3, and the first air outlet 82 is connected to the first storage chamber 30. The floor scrubber also includes a first sealing structure 9, which is movably disposed in the second storage chamber 40, so that the first sealing structure 9 can move to a first sealing position to block the first air inlet 81 or a first avoidance position to avoid the first air inlet 81. Specifically, when the floor scrubber is in the floor scrubbing mode or self-cleaning mode, the first sealing structure 9 moves to the first sealing position; when the floor scrubber is in the vacuuming mode or floor scrubbing and vacuuming mode, the first sealing structure 9 moves to the first avoidance position. With this structural arrangement, by setting the first sealing structure 9, the first air inlet 81 of the exhaust channel 80 can be effectively blocked, thereby preventing communication between the first storage chamber 30 and the second storage chamber 40. This design avoids the risk of sewage backflow caused by a decrease in negative pressure within the sewage tank 3 during floor cleaning mode, reducing the possibility of secondary pollution. Simultaneously, this sealing structure prevents water from entering the exhaust channel 80 through the dust collection box 4 during self-cleaning mode, thus maintaining the cleaning effect.

[0059] The self-cleaning mode mentioned above mainly refers to cleaning the inner walls of the first dust suction channel 56 and the second dust suction channel 520 of the floor scrubber, and using the action of water to condense the dust in the second storage chamber 40 into block-shaped garbage, so that the user can clean it more conveniently later.

[0060] Optionally, the first blocking structure 9 is a blocking plate. The blocking plate is rotatably disposed on one side relative to the first air inlet 81, and the blocking plate can be moved to a first clearance position or a first blocking position by rotating the blocking plate relative to the first air inlet 81.

[0061] Specifically, the floor scrubber also includes: an air guide pipe 10, which is disposed within the first storage chamber 30 and connected to the exhaust pipe 8; the air guide pipe 10 extends along the height direction of the machine body 1, and has a second air inlet 101, a second air outlet 102, and an air guide channel 103 communicating with both the second air inlet 101 and the second air outlet 102; the second air inlet 101 is connected to the exhaust channel 80, and the second air outlet 102 is located at the end of the air guide pipe 10 away from the exhaust pipe 8, and the second air outlet 102 is higher than the preset liquid level of the wastewater tank 3. With this structural arrangement, the air guide pipe 10 guides the air entering the exhaust channel 80, so that the air entering the exhaust channel 80 enters the first storage chamber 30 along the air guide channel 103. At the same time, setting the height of the second air outlet 102 higher than the preset liquid level of the sewage tank 3 can prevent the sewage in the first storage chamber 30 from reaching the preset liquid level and entering the air guide channel 103 through the second air outlet 102, thereby preventing sewage from entering the second storage chamber 40.

[0062] Furthermore, the second air inlet 101 is connected to the exhaust passage 80 through the first air outlet 82.

[0063] Specifically, such as Figure 3 As shown, the wastewater tank 3 has a wastewater inlet 110 that is connected to the first storage chamber 30 and the suction port 20 respectively; the floor scrubber also includes: a guide pipe 11, which is disposed in the first storage chamber 30 and is spaced apart from the air guide pipe 10; the guide pipe 11 extends along the height direction of the body 1, and has a wastewater inlet 110, a guide port 111 and a guide channel 112 that is connected to both the wastewater inlet 110 and the guide port 111; the guide port 111 is located at one end of the guide pipe 11 near the bottom wall of the wastewater tank 3 and is connected to the suction port 20; the wastewater inlet 110 is located at one end of the guide pipe 11 away from the bottom wall of the wastewater tank 3 and is higher than the preset liquid level; wherein, the second air outlet 102 is higher than the wastewater inlet 110. This structural design, with the inclusion of a guide pipe 11, allows ground dirt and grime to flow into the first storage chamber 30 through the guide port 111, guide channel 112, and sewage inlet 110, effectively guiding external dirt and wastewater. Simultaneously, the sewage inlet 110 is designed to be higher than the preset liquid level to prevent wastewater in the first storage chamber 30 from entering the guide channel 112 when the preset liquid level is reached, thus reducing the risk of secondary pollution. Furthermore, the second vent 102 is designed to be higher than the sewage inlet 110 to prevent wastewater flowing out of the sewage inlet 110 from entering the air guide channel 103 through the second vent 102.

[0064] Furthermore, the floor scrubber also includes a wastewater inlet pipe 12, which is connected to the floor brush structure 2 and the wastewater tank 3. The wastewater inlet pipe 12 has a wastewater inlet channel 121, which is connected to the suction port 20 and the guide port 111. When scrubbing the floor, the dirt on the ground enters the first storage chamber 30 in sequence through the suction port 20, the guide port 111, the guide channel 112, and the wastewater inlet 110.

[0065] Specifically, the floor scrubber also includes: a separator, which is detachably installed within the first storage chamber 30 to divide the first storage chamber 30 into a solids chamber and a wastewater chamber, with the solids chamber located above the wastewater chamber; the separator is above a preset liquid level; the separator is equipped with a filter section to filter the wastewater; wherein, both the air guide pipe 10 and the flow guide pipe 11 protrude from the separator. With this structural arrangement, the first storage chamber 30 can be divided into a solids chamber and a wastewater chamber by the separator. Furthermore, the filter section on the separator and the design of the flow guide pipe 11 protruding from the separator allow wastewater to flow out of the inlet 110 and pass through the filter section, leaving solid waste on the separator, effectively separating solid waste from wastewater, reducing the solid content in the wastewater, and lowering the burden on subsequent treatment processes. Moreover, the filter section effectively removes solid matter from the wastewater, improving wastewater treatment efficiency and making subsequent wastewater treatment more efficient, while reducing the risk of equipment clogging. Meanwhile, designing the height of the separator to be higher than the preset liquid level ensures that solid waste is not affected by excessive liquid level, facilitating subsequent solid waste treatment and maintenance, and improving overall work efficiency. The air duct 10 is designed to protrude from the separator so that, in vacuum mode, air entering the second storage chamber 40 can be channeled through the exhaust pipe 8 into the solid waste chamber of the wastewater tank 3. This allows for the removal of moisture from the solid waste on the separator, drying it and preventing the growth of bacteria and odors.

[0066] Furthermore, at least a portion of the air guide tube 10 and the flow guide tube 11 are located within the solid cavity, and both the sewage inlet 110 and the second air outlet 102 are located within the solid cavity.

[0067] Specifically, such as Figures 1 to 4As shown, the floor brush structure 2 includes: a housing 21, a roller brush 22, and a clean water tank 23. The housing 21 has a suction port 20 and a first receiving recess 210. The roller brush 22 is rotatably mounted on the housing 21 and is used for cleaning the floor. The clean water tank 23 is located in the first receiving recess 210 and has a third storage chamber 230 for storing clean water and a water outlet communicating with the third storage chamber 230. When the floor scrubber is in scrubbing mode or scrubbing and vacuuming mode, the clean water in the third storage chamber 230 flows to the roller brush 22 through the water outlet. With this structure, the rotatable design of the roller brush 22 allows for flexible floor cleaning, and the clean water stored in the clean water tank 23 more effectively removes dirt from the floor. The suction port 20 on the housing 21 can suck up wastewater generated during the floor cleaning process in real time, thus preventing wastewater residue on the floor and improving cleaning efficiency. The clean water tank 23 is located in the first receiving recess 210. This compact design not only saves equipment space but also lowers the overall center of gravity of the equipment, thereby improving its stability.

[0068] Furthermore, the clean water tank 23 is detachably disposed in the first receiving recess 210.

[0069] Specifically, the floor brush structure 2 also includes a water pump, with its inlet and outlet connected, and its outlet connected to the roller brush 22, to deliver clean water from the third storage chamber 230 to the roller brush 22. This structural arrangement, with the water pump providing a stable and continuous water flow, allows for more even spraying of clean water onto the roller brush 22, thereby improving cleaning efficiency. Furthermore, the powerful delivery of clean water from the third storage chamber 230 to the roller brush by the water pump helps to quickly wet the floor, reducing the adhesion of dirt and making the cleaning process more efficient. At the same time, the water pump can adjust the water flow according to cleaning needs, avoiding excess water waste and ensuring the use of the optimal amount of clean water during the cleaning process, achieving an environmentally friendly effect.

[0070] Specifically, such as Figures 1 to 4As shown, the clean water tank 23 is provided with a cleaning port 231, which is connected to the third storage chamber 230; the floor brush structure 2 also includes a second sealing structure, which is movably disposed in the third storage chamber 230 so that the second sealing structure can move to a second sealing position to block the cleaning port 231 or a second avoidance position to avoid the cleaning port 231; wherein, when the suction port 50 enters the third storage chamber 230 through the cleaning port 231, the second sealing structure moves to the second avoidance position, and when the suction port 50 moves away from the cleaning port 231, the second sealing structure moves to the second sealing position. This structural design, with the cleaning port 231, allows the suction port 50 to easily enter the third storage chamber 230. During self-cleaning, clean water can sequentially enter the first suction channel 56, the second suction channel 520, and the second storage chamber 40 through the suction port 50. This clean water washes the inner walls of the first and second suction channels 56 and 520, and the water also helps to clump the dust in the second storage chamber 40 into smaller clumps for easier cleaning later. Simultaneously, the second sealing structure prevents the third storage chamber 230 from being sealed during non-self-cleaning operations, preventing water from leaking out of the cleaning port 231 and preventing impurities from entering the third storage chamber 230. This avoids the risk of secondary contamination, protects the internal water pump and other mechanisms, and reduces the failure rate. It also helps maintain the purity of the clean water.

[0071] Furthermore, the second sealing structure includes a sealing element and an elastic element. One end of the elastic element is mounted on the wall of the third storage cavity 230, and the other end of the elastic element faces the cleaning port 231. The sealing element is mounted on the other end of the elastic element and is positioned above the elastic element. The elastic element has a natural state and a compressed state. When the elastic element is in the natural state, it positions the sealing element in the second sealing position to seal the cleaning port 231. When the dust guide tube 55 applies pressure to the sealing element, it compresses the elastic element, causing the sealing element to move to the second clearance state, positioning the suction port 50 within the third storage cavity 230. The restoring force of the elastic element allows the sealing element to switch between the second clearance state and the second sealing position.

[0072] Optionally, the elastic element is a spring.

[0073] Specifically, the floor brush structure 2 also includes a drive assembly, which is connected to the roller brush 22 for driving the roller brush 22 to rotate.

[0074] Specifically, the floor brush structure 2 also includes a hanging strip assembly, which is disposed on the housing 21. The hanging strip assembly is used to fix the roller brush and works in conjunction with the roller brush to ensure that the roller brush maintains the correct posture and position during operation and to provide additional support and stability.

[0075] Specifically, the floor brush structure 2 also includes a roller assembly 24, which is rotatably mounted on the housing 21. The roller assembly 24 is used to assist the floor scrubber in moving, making it easier for users to push or pull the floor scrubber, especially when moving over a large area, thus improving the ease of operation.

[0076] Specifically, the floor scrubber also includes an energy storage structure 13, which is disposed within the machine body 1. The energy storage structure 13 is used to store electrical energy and provide electrical energy to the floor scrubber. The energy storage structure 13 is connected to a control structure, which is used to control the charging and discharging of the energy storage structure 13.

[0077] Optionally, the energy storage structure 13 is an energy storage battery.

[0078] Specifically, the floor scrubber also includes a selection button located on the machine body 1. Users can select different operating modes using the selection button. A control structure is connected to the selection button and is used to send commands to the control structure via the selection button. The control structure then executes the corresponding operating mode based on the user's commands.

[0079] Specifically, the floor scrubber also includes: a base structure, which includes a base housing, a charging component, and a blowing component. Both the charging component and the blowing component are mounted on the base housing. The charging component is used to charge the energy storage structure 13, and the blowing component is used to dry the roller brush 22.

[0080] Optionally, the working process of the floor scrubber is as follows:

[0081] When the user needs to vacuum, the user separates the grip part 51 from the body 1, and then pulls out at least a portion of the vacuum hose 52 according to the cleaning needs. When the grip part 51 is separated from the body 1, the floor scrubber automatically switches to vacuum standby mode (i.e., in this state, the floor scrubber is ready to perform vacuuming operations), and when the user presses the first vacuum button 53 or the second vacuum button 54, the second fan 7 starts to rotate (i.e., enters vacuuming mode). By holding the grip part 51, the user directs the vacuum nozzle 50 toward the area to be cleaned. Dust and air in the area to be cleaned are sucked into the dust guide channel 551 through the vacuum nozzle 50, and then sequentially enter the second storage chamber 40 of the dust collection box 4 through the first vacuum channel 56, the second vacuum channel 520, and the second fan 7. Simultaneously, when the user presses the first vacuum button 53 or the second vacuum button 54, the first sealing structure 9 moves to the first clearance position, allowing air entering through the first air inlet 81, exhaust channel 80, first air outlet 82, second air inlet 101, air guide channel 103, and second air outlet 102 to enter the first storage chamber 30 of the wastewater tank 3, drying the solid waste on the separator. When the vacuuming work is completed, the gripping part 51 is inserted into the body 1.

[0082] When a user needs to clean the floor, they select the cleaning mode via a selection button. Upon receiving the command, the control structure controls at least a portion of the first fan 6 and the floor brush structure 2 to move. At this time, the first sealing structure 9 is in the first sealing position to block the exhaust channel 80, preventing the first storage chamber 30 from communicating with the second storage chamber 40. Then, the user applies a pushing force to the roller assembly 24 of the floor brush structure 2 by holding the gripping component 51, causing the floor scrubber to move within the cleaning area. Water from the clean water tank 23 of the floor brush structure 2 flows onto the roller brush 22, causing it to rotate and clean the floor. During the cleaning process, dirt on the floor is sucked into the inlet channel 121 through the suction port 20, and then sequentially enters the solid waste chamber through the guide port 111, the guide channel 112, and the inlet port 110. Solid waste remains on the separator, while wastewater enters the wastewater chamber through the filter section of the separator.

[0083] When a user needs to vacuum while washing the floor, firstly, the user separates the grip part 51 from the body 1 and pulls out at least a portion of the suction pipe 52 according to the cleaning needs. Next, the user can choose to press the first suction button 53 or the second suction button 54 to activate the second fan 7. At the same time, the user can switch to the floor washing mode by selecting a button, thereby activating the first fan 6 and the floor brush structure 2. The user can also choose to directly switch to the floor washing and vacuuming mode. When performing vacuuming and floor washing operations simultaneously, the user can use both hands to hold the grip part 51 and the first groove 100 on the body 1 respectively, facilitating effective vacuuming and floor washing operations on the cleaning area at the same time.

[0084] At the same time, when the first fan 6 and the second fan 7 rotate together, the first sealing structure 9 moves to the first clearance position to increase the negative pressure of the sewage tank through the first fan 6 and the second fan 7, thereby increasing the suction of the floor scrubber and allowing the dirt on the ground to quickly enter the first storage chamber 30.

[0085] When the user needs to clean the vacuum hose, firstly, the user separates the grip 51 from the body 1 and pulls out at least a portion of the vacuum hose 52 as needed. Next, the user inserts the dust guide tube 55 into the third storage chamber 230 of the clean water tank 23, aligned with the cleaning port 231. At this time, the second sealing structure is in the second clearance position. Then, the user switches to the self-cleaning mode via the selection button, and the second fan 7 starts, drawing water into the dust guide channel 551. The water then flows sequentially through the first suction channel 56, the second suction channel 520, and the first connecting channel of the second fan 7, entering the second storage chamber 40. This cleans the dust guide channel 551, the first suction channel 56, and the second suction channel 520, and uses water to form clumps of dust in the second storage chamber 40 for easy cleaning later. After cleaning, the user inserts the grip 51 back into the body 1, at which point the second sealing structure is in the second sealing position.

[0086] At the same time, when the floor scrubber is in self-cleaning mode, the first sealing structure 9 is in the first sealing position to block the exhaust channel 80, so that the first storage chamber 30 and the second storage chamber 40 are not connected.
