Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a floor brush assembly, surface cleaning equipment, and cleaning system. Background Technology

[0002] With the continuous innovation of cleaning equipment technology, people's pursuit of cleaning efficiency and convenience is increasing day by day. In particular, surface cleaning equipment such as floor scrubbers, with their multi-functional features of sweeping, mopping, and drying, have become important equipment for modern home cleaning and are widely used in various scenarios such as homes, offices, and commercial venues.

[0003] Traditional surface cleaning equipment has many shortcomings in its structural design and functional implementation. Take a common floor scrubber as an example: it typically consists of a main body and a brush assembly. The main body has a handheld grip for easy handling. During cleaning, the operator pushes the main body by gripping the handheld grip, which in turn moves the brush assembly across the surface to be cleaned. However, the water supply and wastewater collection functions of traditional floor scrubbers often rely on clean water and wastewater tanks located on the main body and far from the brush assembly. This layout has significant drawbacks. Because the clean water and wastewater tanks are far from the brush assembly and located on the upper part of the main body, the overall center of gravity of the cleaning equipment is high. During operation, users need to expend more effort to maintain the balance of the equipment, especially during prolonged use or cleaning large areas, easily leading to wrist fatigue and severely affecting the comfort and convenience of use.

[0004] To address this, existing technologies design both the clean water tank and the waste water tank to be mounted on the floor brush assembly. While this structure overcomes the aforementioned drawbacks, it still presents the following problems: If the clean water tank and waste water tank are laid flat in the horizontal direction, the clean water tank gradually becomes lighter and the waste water tank gradually becomes heavier as cleaning progresses, causing the floor brush assembly to lose its balance. If the clean water tank and waste water tank are stacked, although this solves the problem of imbalance in the floor brush assembly during cleaning, it results in an excessively thick floor brush assembly, making it unable to clean corner areas.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0065] It should be noted that, in this utility model, "front-back direction" refers to the direction of movement of the floor brush assembly 100 during normal cleaning operations, wherein the direction toward the area to be cleaned is "front," and the direction away from the area to be cleaned is "back." "Horizontal" refers to the horizontal direction perpendicular to the front-back direction, that is, the width direction of the floor brush assembly 100; "vertical direction" refers to the direction approximately perpendicular to the surface to be cleaned, wherein the direction closer to the surface to be cleaned is "down," and the direction farther away from the surface to be cleaned is "up."

[0066] Example 1:

[0067] Specifically, this utility model provides a cleaning system. In this embodiment, the cleaning system includes a base (or base station) and a surface cleaning device 1000 provided by this utility model, wherein the surface cleaning device 1000 includes a floor brush assembly 100 provided by this utility model. The base (or base station) may be provided with a positioning structure adapted to the surface cleaning device 1000 to ensure the stability of the surface cleaning device 1000 when placed. A charging module may be integrated inside the base, with its charging contacts corresponding to the charging interface of the surface cleaning device 1000 to achieve automatic charging. In a preferred embodiment, the base may also be provided with a cleaning mechanism for cleaning the cleaning components 20 of the surface cleaning device 1000. The base may also be provided with a drain pipe connected to the dirt collection module of the surface cleaning device 1000, which discharges wastewater to an external sewer through a pump or gravity.

[0068] Please see Figure 1 The surface cleaning device 1000 provided by this utility model includes a floor brush assembly 100 and a body 200, as shown in the figure. The lower end of the body 200 is connected to the floor brush assembly 100 through a connecting part 17. Preferably, the connecting part 17 is a rotating connecting part 17, which allows the floor brush assembly 100 to rotate flexibly relative to the body 200 to adapt to different slopes of the surface to be cleaned. The rotating connecting part 17 can be a pin and shaft hole fit structure, or it can be a ball joint structure.

[0069] Furthermore, a handheld part 201 is provided at the upper end of the main body 200. The surface of the handheld part 201 may be covered with anti-slip rubber and may also have raised buttons, making it convenient for users to operate and control the device to start and stop, and switch modes (such as wet mopping / dry vacuuming modes) during cleaning. The floor brush assembly 100 includes a cleaning component 20. The specific form of the cleaning component 20 is not limited and can be selected as a roller brush (with an outer layer of microfiber, suitable for cleaning floor tiles) or a cleaning cloth (adhesive-attached, suitable for wood floors), etc. The cleaning component 20 can be driven to rotate or move with the device to rub the surface to be cleaned, achieving deep cleaning of the surface to be cleaned.

[0070] In this embodiment, the user holds the handheld part 201 and pushes the body 200. The floor brush assembly 100 adjusts its angle by rotating the connecting part 17 to fit the surface to be cleaned. The liquid supply module and the dirt collection module of the surface cleaning device 1000 work together under the command of its internal controller to supply liquid to the cleaning parts 20 as needed, or to absorb dirt on the surface to be cleaned.

[0071] Please see Figures 2 to 14This utility model provides a floor brush assembly 100. In this embodiment, the floor brush assembly 100 includes a base 10, a cleaning component 20, a liquid supply module, and a dirt collection module. The base 10 is preferably made of ABS plastic through one-piece injection molding, which has the characteristics of lightweight and high strength, providing support and installation space for the various components in the floor brush assembly 100. The cleaning component 20 is mounted on the base 10. In this embodiment, as shown... Figure 2 and Figure 3 As shown, the cleaning component 20 is a roller brush rotatably mounted on the base 10. The roller brush is driven by a motor to rotate and rub the surface to be cleaned. A suction port 22 is formed on the base 10, facing the cleaning component 20. The suction port 22 is preferably located behind the roller brush to promptly absorb dirt generated during the cleaning process. The liquid supply module includes a first housing 31 mounted on the base 10. The first housing 31 can store clean water or a cleaning solution mixed with cleaning agents. Its material is preferably transparent plastic to facilitate user observation of the liquid level and timely addition of water. The liquid supply module has an outlet 21 connected to the first housing 31 and facing the cleaning component 20. Preferably, the outlet 21 is a plurality of small holes provided on the water distributor 34 to evenly spray the cleaning solution onto the cleaning component 20. The dirt collection module includes a second housing 41 mounted on the base 10. The second housing 41 is connected to the suction port 22 and is used to store dirt, which may contain wastewater and solid impurities.

[0072] In this embodiment, when the surface cleaning device 1000 performs cleaning operations, the cleaning liquid in the first housing 31 is evenly sprayed onto the cleaning component 20 or the surface to be cleaned through the outlet 21. The cleaning component 20 rubs against the surface to be cleaned to remove stains. At the same time, the dirt collection module generates negative pressure, sucking wastewater and solid impurities into the second housing 41 for storage through the suction port 22. Since both the first housing 31 and the second housing 41 are integrated into the floor brush assembly 100, compared to the solution of setting the first housing 31 or the second housing 41 on the body 200, the overall center of gravity of the surface cleaning device 1000 is lower, making the operation more stable and effortless for the user, thus improving the user's operating experience. In addition, the distance between the first housing 31 and the outlet 21, and between the second housing 41 and the suction port 22, is shorter, which greatly shortens the length of the internal dirt suction or liquid supply pipeline 36, reducing the resistance in the pipeline and the risk of pipeline failure and leakage. Furthermore, the center of gravity of the first box 31 and the second box 41 is closer to the cleaning component 20, which increases the pressure of the cleaning component 20 on the surface to be cleaned, making the fit between the cleaning component 20 and the surface to be cleaned more stable, thereby improving cleaning efficiency and effect.

[0073] Based on the previous embodiment, the layout of the first housing 31 and the second housing 41 on the base 10 can be designed as needed. For example, the first housing 31 and the second housing 41 can be arranged side by side in the front-to-back direction, or they can be arranged side by side in the transverse direction. In this embodiment, please refer to... Figures 3 to 6The first box 31 and the second box 41 are stacked vertically. Specifically, the second box 41 can be positioned below (closer to the surface to be cleaned) and the first box 31 above, or the first box 31 can be positioned below and the second box 41 above. Furthermore, in this embodiment, the projected area of ​​the first box 31 in the vertical direction is larger than that of the second box 41, or vice versa.

[0074] It is understandable that during the cleaning process, the mass of the first housing 31 gradually decreases due to liquid supply, while the mass of the second housing 41 gradually increases due to dirt collection. If the first housing 31 and the second housing 41 are arranged side by side in the horizontal direction, the center of gravity of the entire floor brush assembly 100 will continuously shift from the first housing 31 to the second housing 41 as the cleaning operation progresses. This is detrimental to the overall stability of the floor brush assembly 100, causing the cleaning component 20 to easily lift up locally, resulting in insufficient adhesion to the component to be cleaned. Furthermore, in this embodiment, the stacked arrangement of the first housing 31 and the second housing 41 makes the structure of the floor brush assembly 100 more compact and smaller in the horizontal direction. In particular, the reduction in the lateral dimension allows the surface cleaning device 1000 to reach deep into furniture crevices for cleaning, reducing cleaning dead angles.

[0075] Furthermore, the vertical layout design brings the center of gravity of the floor brush assembly 100 closer to the top of the cleaning component 20. The centers of gravity of the first housing 31 and the second housing 41 are highly aligned vertically, and the resultant force line of the floor brush assembly 100 is basically consistent with the support center line of the base 10. This more balanced and stable center of gravity enhances the pressure of the cleaning component 20 on the surface to be cleaned, allowing it to adhere more stably to the surface. In addition, the projected area of ​​the first housing 31 in the vertical direction is larger than that of the second housing 41, or vice versa. That is, the projections of the first housing 31 and the second housing 41 in the vertical direction do not completely overlap; one of them extends beyond the other in the horizontal direction. The space between them in the vertical direction can be used to install other components of the floor brush assembly. This design makes the floor brush assembly 100 more compact and smaller in size, allowing it to navigate low-lying areas, further reducing cleaning dead spots and improving cleaning effectiveness.

[0076] Furthermore, please refer to the following: Figure 10A cavity 12 is formed in the base 10, which is used to accommodate at least part of the liquid supply module and / or the dirt collection module. Specifically, the cavity 12 is located behind the second housing 41, and the first housing 31 is stacked on top of the second housing 41. The rear end of the first housing 31 extends above the cavity 12, and the projected area of ​​the first housing 31 in the vertical direction is larger than that of the second housing 41. With this arrangement, the power components, power supply, and other components in the floor brush assembly 100 are installed in the staggered space between the first housing 31 and the second housing 41 in the vertical direction, making the overall structure of the floor brush assembly 100 more compact, and especially effectively reducing the size of the brush assembly 100 in the vertical direction.

[0077] In a preferred embodiment, such as Figure 10 As shown, the base 10 has a mounting cavity 11 with an opening 111 on the upper side, located in front of the cavity 12. A second housing 41 is embedded in the mounting cavity 11, and a first housing 31 is mounted on the base 10 and stacked on top of the second housing 41. In this embodiment, the weight of the first housing 31 acts directly on the top of the second housing 41 through its bottom. Because the second housing 41 is embedded in the mounting cavity 11, its weight (its own weight plus the weight of the first housing 31) is transmitted to the base 10 through the bottom wall 112 of the mounting cavity 11, ultimately concentrating on the contact area between the cleaning component 20 and the surface to be cleaned. This layer-by-layer transfer of gravity effectively increases the normal pressure exerted by the cleaning component 20 on the surface to be cleaned. With the same housing capacity, this layout design significantly increases the pressure of the cleaning component 20 on the surface to be cleaned. The second housing 41 is embedded in the mounting cavity 11. The side wall of the mounting cavity 11 will form a lateral constraint on the second housing 41, limiting its displacement in the horizontal direction. When the surface cleaning equipment 1000 moves (such as when turning or passing over undulating ground), gravity will not generate a significant eccentric torque, which improves the problem of the base 10 shaking or the cleaning part 20 being unstable in contact with the ground due to gravity offset.

[0078] Preferably, the second housing 41 can be partially or completely embedded in the mounting cavity 11, and a handle can also be provided on the second housing 41. The first housing 31 is preferably detachably mounted on the base 10. When the second housing 41 needs to be cleaned and maintained, the first housing 31 can be disassembled first, and then the second housing 41 can be lifted for maintenance and cleaning. The connection structure between the first housing 31 and the base 10 can be designed as needed.

[0079] Optionally, please refer to Figure 10The first housing 31 covers the upper side of the mounting cavity 11. The first housing 31 is provided with a snap-fit ​​part 312, and the base 10 is provided with a snap-fit ​​mating part 18. The snap-fit ​​part 312 and the snap-fit ​​mating part 18 cooperate to allow the first housing 31 to be detachably installed on the base 10. The snap-fit ​​part 312 and the snap-fit ​​mating part 18 are preferably designed as a matching buckle and a matching groove. Through their snap-fit ​​engagement, the first housing 31 is securely installed while also facilitating disassembly. In this embodiment, when the first housing 31 is placed on top of the second housing 41, the snap-fit ​​part 312 automatically engages with the snap-fit ​​mating part 18, thus fixing the first housing 31. The operation is simple and the connection is reliable.

[0080] Furthermore, please refer to the following: Figure 8 and Figure 9 The base 10 also forms a cavity 12, which is located behind the mounting cavity 11 and is used to accommodate other components of the liquid supply module and the sludge collection module. The liquid supply module includes a first pump body 32 disposed within the cavity 12. The outlet end of the first pump body 32 is connected to an outlet 21 for pumping cleaning fluid from the first housing 31 to the outlet 21. The rear end of the first housing 31 extends above the cavity 12. The liquid supply module also includes a valve assembly 33, through which the first pump body 32 is detachably connected to the first housing 31. The valve assembly 33 is configured to automatically close when the first housing 31 is removed to prevent leakage. Preferably, as shown... Figure 14 As shown, the base 10 includes a detachable upper housing 110 and a lower housing 120. The mounting cavity 11 is formed in the upper housing 110. The upper housing 110 and the lower housing 120 together cover each other to form a cavity 12. All components in the cavity 12 are fixed to the lower housing 120. When it is necessary to inspect the components inside the cavity 12, the upper housing 110 can be disassembled and lifted.

[0081] In this embodiment, the other components of the liquid supply module and the dirt collection module are housed in the cavity 12 behind the mounting cavity 11, making the center of gravity of the floor brush assembly 100 more evenly distributed in the front-to-back direction, thus avoiding the difficulty of pushing the floor brush assembly 100 due to its front-heavy and rear-light weight distribution. The first pump body 32 operates in the cavity 12, drawing cleaning fluid from the first tank 31 through the valve assembly 33. The rear extension of the first tank 31 increases the liquid storage capacity, and at the same time, it is connected to the first pump body 32 through the valve assembly 33. The design of the valve assembly 33 ensures that when the first tank 31 is installed in place, it is connected to the first pump body 32, and when the first tank 31 is disassembled, the first tank 31 is sealed to prevent leakage.

[0082] Specifically, please refer to the following: Figure 10 and Figure 11The valve assembly 33 includes a first connector 331 (preferably located at the upper end of the first pump body 32) and a second connector 332 (preferably located at the bottom of the first housing 31) disposed in the first housing 31. Preferably, the first connector 331 is made of rigid plastic and is provided with a sealing ring, while the second connector 332 may be made of elastic material and be designed to fit the first connector 331. The inlet end of the first pump body 32 is connected to the first connector 331, and the outlet end of the first pump body 32 is connected to the outlet 21. The first connector 331 passes through the top wall 121 of the cavity 12 and is detachably connected to the second connector 332.

[0083] In this embodiment, when the first housing 31 is placed above the cavity 12, the second connector 332 mates with the first connector 331, and the two are connected. The deformation of the elastic material fills the gap 13 to achieve a seal. When the first housing 31 is disassembled, the second connector 332 separates from the first connector 331, and the second connector 332 elastically resets to close the channel. The design of the detachable and connectable first connector 331 and second connector 332 allows the disassembly and assembly of the first housing 31 to be done without additional tools. When installing the first housing 31, simply place it on the base 10, and the second connector 332 will automatically align with and mate with the first connector 331 under gravity. When disassembling, simply lift the first housing 31 to separate the second connector 332 from the first connector 331. At this time, the second connector 332 automatically closes the channel due to elastic reset, preventing residual cleaning fluid from leaking.

[0084] Optionally, such as Figure 9 and Figure 14 As shown, the liquid supply module also includes a liquid supply pipe 36 installed in the base 10. A gap 13 extending in the front-to-back direction is formed in the base 10. The width of the gap 13 should be set to be greater than the outer diameter of the pipe to prevent the pipe from being blocked by pressure. The gap 13 is located on at least one side of the mounting cavity 11 in the lateral direction, such as the left or right side, which can be selected according to the pipe layout. The rear end of the liquid supply pipe 36 is located in the cavity 12 and communicates with the first housing 31. Preferably, the rear end of the liquid supply pipe 36 communicates with the liquid outlet of the first pump body 32, thereby communicating with the first housing 31. The front end of the liquid supply pipe 36 is located in front of the mounting cavity 11 and communicates with the liquid outlet 21. In this embodiment, the liquid supply pipe 36 is placed using the gap 13 on the upper lateral side of the mounting cavity 11, which does not occupy the vertical dimension of the floor brush assembly 100, making the vertical structure of the floor brush assembly 100 more compact and smaller in size, which is beneficial for the surface cleaning device 1000 to clean low crevices.

[0085] Please refer to the following: Figure 6 and Figure 9The dashed arrows in the figure indicate the exhaust direction in the sludge collection assembly. In an optional embodiment, the base 10 includes a partition wall 14 disposed between the mounting cavity 11 and the cavity 12, and an exhaust port 141 is provided on the partition wall 14, which connects to the second housing 41. The sludge collection module also includes a fan assembly 42, which is at least partially disposed within the cavity 12, and the exhaust end of the fan assembly 42 faces the rear of the base.

[0086] Preferably, the dirt collection module further includes a filter 43 (generally a HEPA filter). The exhaust port 141, filter 43, and fan assembly 42 are arranged sequentially from front to back. The fan assembly 42 generates negative pressure during operation, drawing air from the second housing 41 through the filter 43 and exhaust port 141, creating a negative pressure suction effect in the second housing 41. The airflow enters the second housing 41 from the suction port 22, then passes through the filter 43 from the exhaust port 141, and is discharged from the exhaust end of the air outlet assembly to the rear of the floor brush assembly 100. In this embodiment, the second housing 41, filter 43, and fan assembly 42 are arranged sequentially from front to back. On the one hand, this allows the exhaust air to be directed to the rear of the base 10, avoiding interference with the cleaning in front. On the other hand, the structure is compact, the exhaust path is short, and malfunctions are less likely to occur.

[0087] Furthermore, please continue to refer to [the relevant sources]. Figure 10 , Figure 12 and Figure 13 The second housing 41 includes a main body 411 and a cover 412, which are detachably connected. A partition 413 is installed inside the main body 411, dividing it into a first chamber 4111 and a second chamber 4112 arranged horizontally. The first chamber 4111 is used for initial sludge collection and storage of solid impurities, while the second chamber 4112 is used for storing wastewater. The bottoms of the first chamber 4111 and the second chamber 4112 are connected, allowing wastewater flow but blocking large solid impurities. An air duct 4121 is formed inside the cover 412 and is located on the upper side of the main body 411. The suction port 22 is located at the front of the main body 411 and connects to the first chamber 4111. The air inlet of the air duct 4121 in the cover 412 connects to the top of the first chamber 4111, while the air outlet connects to the exhaust port 141.

[0088] In this embodiment, under the negative pressure provided by the blower assembly 42, the sludge mixed with solid impurities and sewage enters the first chamber 4111 through the suction port 22. The solid impurities settle, and the sewage flows into the second chamber 4112 through the bottom connection. Optionally, the sludge collection module also includes a second pump body disposed in the cavity 12. The second pump body is connected to the second chamber 4112 and draws air through the pipeline to form a negative pressure, causing the sewage in the first chamber 4111 to flow to the second chamber 4112. Alternatively, the exhaust port 141 is connected to the second chamber 4112, and the negative pressure of the blower assembly 42 directly acts on the second chamber 4112, driving the sewage in the first chamber 4111 to flow. The negative pressure of the blower assembly 42 can act on the first chamber 4111 through the air duct 4121 to accelerate the transfer of sewage. It can also provide other negative pressure devices to connect the second chamber 4112, providing a pressure difference between the second chamber 4112 and the first chamber 4111, causing sewage to flow from the first chamber 4111 into the second chamber 4112. Gas flows from the top of the first chamber 4111 into the air duct 4121 in the cover body 412, and flows through the filter device from the exhaust port 141 before being discharged through the blower assembly 42.

[0089] In this embodiment, through the structural design of the second box 41, the main body 411 is divided into a first chamber 4111 and a second chamber 4112 by a partition 413, with only the bottom connected. This achieves efficient solid-liquid separation, allowing impurities such as hair and debris to settle in the first chamber 4111, while wastewater flows into the second chamber 4112. Preferably, as follows... Figure 13 As shown, a slag basket 47 is detachably installed in the first chamber 4111. When solid waste needs to be cleaned, the slag basket 47 can be removed for cleaning. The air duct 4121 inside the cover body 412 is designed to optimize the airflow path. The air duct 4121 is located above the first chamber 4111 and the second chamber 4112, which increases the sludge storage capacity of the first chamber 4111 and the second chamber 4112.

[0090] Preferably, please refer to the following: Figure 5 , Figure 13 and Figure 14 A first protrusion 15 is provided on the bottom wall 112 of the mounting cavity 11. The first protrusion 15 is preferably integrally formed from the base 10. A suction channel 151 is formed in the first protrusion 15, and a suction port 22 is formed at the lower end of the suction channel 151. This suction port 22 is located behind the cleaning component 20 and opens forward. A suction interface 152 is formed at the upper end of the suction channel 151. A sealing ring can be installed at this suction interface 152, and it opens upward. The main body 411 of the box has an interface channel 45. The inlet of the interface channel 45 opens downward, and the outlet of the interface channel 45 is located at the partition 413 and faces the first compartment 4111. The upper end of the first protrusion 15 is inserted into the interface channel 45 from the inlet, and the sealing ring is compressed to achieve a seal.

[0091] In this embodiment, the suction channel 151 is connected to the second housing 41 by the insertion of the first protrusion 15 and the interface channel 45, and the sealing ring ensures that the negative pressure does not leak. This insertion structure allows for automatic alignment of the suction channel 151 and the interface channel 45 when the second housing 41 is installed into the mounting cavity 11, without the need for manual alignment. This achieves communication between the suction port 22 and the first chamber 4111, while ensuring a seal. The suction path is short and the structure is simple, easy to manufacture, and less prone to leakage or blockage.

[0092] Optionally, please refer to Figure 6 and Figure 12 A second protrusion 46 is provided on the rear side wall of the box body 411. The second protrusion 46 is preferably integrally formed with the box body 411. An air outlet channel 461 is formed in the second protrusion 46. The lower end of the air outlet channel 461 forms a rearward opening 462, which connects to the exhaust port 141. The upper end of the air outlet channel 461 forms an upward opening 463, which connects to the air outlet end of the air duct 4121. Preferably, a silicone gasket is provided at the connection point for sealing.

[0093] In this embodiment, the airflow in the air duct 4121 enters the air outlet duct 461 through the second opening 463, flows through the first opening 462 and the exhaust port 141 to the filter 43, and the silicone gasket prevents airflow leakage. Through the design of this air outlet duct 461, when the cover 412 is installed on the upper side of the main body 411, the air duct 4121 and the air outlet duct 461 are connected. When the second housing 41 is fully embedded and installed in the mounting cavity 11, the air outlet duct 461 and the exhaust port 141 are connected. The sealing effect of the silicone gasket ensures that the airflow can smoothly flow into the filter 43 and the fan assembly 42, reducing negative pressure loss.

[0094] Based on the above embodiments, please continue to refer to Figure 5 , Figure 9 and Figure 14The base 10 has a mounting groove 16 with an upper opening 111 at its rear end. A connecting part 17 is provided on the base 10 within the mounting groove 16. The floor brush assembly 100 is connected to the body 200 via the connecting part 17. The cavity 12 is U-shaped and surrounds the front and lateral sides of the mounting groove 16. In this embodiment, the mounting groove 16 has an upper opening 111 and a built-in connecting part 17, concentrating the connection point between the floor brush assembly 100 and the body 200 in the central area of ​​the rear end of the base 10. This ensures that the force transmitted by the body 200 acts on the rear center of the floor brush assembly 100, making the force on the floor brush assembly 100 more balanced and easier to operate when the user moves it. Furthermore, the U-shaped cavity 12's surrounding layout of the mounting groove 16 improves space utilization, allowing larger, heavier components to be placed in the lateral areas of the mounting groove 16. This also makes the overall weight distribution of the floor brush assembly 100 more balanced and easier to move.

[0095] Based on the previous embodiment, such as Figure 1 and Figure 10 As shown, the first housing 31 has a through notch 311 extending vertically. The projection of the notch 311 in the vertical direction at least partially coincides with the mounting groove 16, allowing the lower end of the body 200 and / or the connecting part 17 located in the mounting groove 16 to pass through the notch 311. The edges of the notch 311 are rounded to avoid scratching the components. Preferably, the part of the base 10 corresponding to the fan assembly 42 protrudes upward at least partially and is also embedded in the notch 311. The design of the notch 311 allows the first housing 31 to extend further rearward, resulting in a larger horizontal area and a correspondingly lower vertical dimension, further reducing the vertical dimension of the floor brush assembly 100. In addition, the notch 311 also allows the fan assembly 42 to be designed higher. While ensuring the negative pressure effect, the higher part of the fan assembly 42 does not overlap with the first housing 31 in the vertical direction, making the structure of the floor brush assembly 100 more compact and its vertical dimension smaller.

[0096] Optionally, such as Figure 9 and Figure 14 As shown, the floor brush assembly 100 also includes a battery module 50 and a fan assembly 42 disposed within the cavity 12, with the air inlet of the fan assembly 42 connected to the second housing 41. The battery module 50 and the fan assembly 42 are respectively disposed on both sides of the mounting groove 16 in the horizontal direction.

[0097] In this embodiment, the battery module 50 supplies power to the fan assembly 42, the first pump body 32, etc., and the two are respectively arranged on both sides of the mounting groove 16 to balance the center of gravity of the floor brush assembly 100 in the lateral direction. The fan assembly 42 is located at the rear end of the base 10, which is conducive to the direct exhaust of gas from the rear side of the base 10. The mass of the battery module 50 is close to that of the fan assembly 42, which can effectively balance the center of gravity of the floor brush assembly 100 in the lateral direction, making it convenient for the user to hold the body 200 and push the floor brush assembly 100 to move. The battery assembly is integrated in the cavity 12 and is close to the first pump body 32 and the fan assembly 42, which is conducive to wiring.

[0098] Optionally, such as Figure 14 As shown, the liquid supply module also includes a disinfection module 35, which is generally used to provide electrolyzed water. It is connected between the first pump body 32 and the outlet 21, giving the water flowing from the outlet 21 disinfection properties. The disinfection module 35, the first pump body 32, and the filter 43 are arranged sequentially in the transverse direction within the cavity 12. The disinfection module 35 is located between the mounting cavity 11 and the battery module 50 in the front-back direction. The filter 43 is located between the mounting cavity 11 and the fan assembly 42. The first pump body 32 is located between the mounting cavity 11 and the mounting groove 16. These three components are spaced apart to avoid mutual interference.

[0099] In this embodiment, the relatively lightweight disinfection module 35, the first pump body 32, and the filter 43 are located between the second housing 41 and the battery module 50 and the fan assembly 42 in the front-back direction, so that the weight of the floor brush assembly 100 is distributed in the front-back direction as heavy-light-heavy. On the one hand, the compact layout makes the cavity 12 smaller and the floor brush assembly 100 lighter and thinner. On the other hand, the center of gravity of the floor brush assembly 100 is balanced, making it less likely to tip forward or backward.

[0100] Based on the above embodiments, such as Figure 6 As shown, the sludge collection module also includes a fan assembly 42 connected to the second housing 41, with the air outlet of the fan assembly 42 facing the rear of the base 10. The cleaning component 20, the second housing 41, and the fan assembly 42 are arranged sequentially from front to back. The total dimension of the floor brush assembly 100 in the front-to-back direction is D; the dimension of the cleaning component 20 in the front-to-back direction is D1 / D, which is greater than or equal to 0.15 and less than or equal to 0.18; and / or, the dimension of the second housing 41 in the front-to-back direction is D2, where D2 / D is greater than or equal to 0.3 and less than or equal to 0.4; and / or, the dimension of the fan assembly 42 in the front-to-back direction is D3, where D3 / D is greater than or equal to 0.2 and less than or equal to 0.3.

[0101] In this embodiment, the cleaning component 20, the second housing 41, and the blower assembly 42 are arranged sequentially from front to back, forming an efficient work process. The cleaning component 20 directly acts on the surface to be cleaned at the front, followed by the second housing 41 which promptly sucks away wastewater through the suction port 22 to prevent wastewater from spreading. The blower assembly 42 at the rear provides negative pressure power. The three components form a continuous "cleaning-sewage suction-power" work chain, reducing the time wastewater stays on the ground and effectively improving the drying speed of the ground. At the same time, the air outlet of the blower assembly 42 is opened to the rear, so the exhaust airflow will not interfere with the cleaning area in front and avoid blowing up uncleaned dust and causing secondary pollution.

[0102] The dimensions of each component in the front-to-back direction are controlled within a specific range as a proportion of the total size of the floor brush assembly 100. This optimized proportion allows each component to fully perform its function. Specifically, the size ratio of the cleaning component 20 (D1 / D) is greater than or equal to 0.15 and less than or equal to 0.18. This ensures that the contact area between the cleaning component 20 and the ground is sufficient to cover a single cleaning path, while avoiding increased rotational resistance or reduced flexibility due to excessive size. Under the same thrust, this proportion of the cleaning component 20 can effectively improve cleaning efficiency. The size ratio of the second housing 41 (D2 / D) is greater than or equal to 0.3 and less than or equal to 0.4, providing ample space for wastewater storage. Combined with its front-to-back position, it can effectively receive wastewater behind the cleaning component 20, reducing wastewater residue on the ground. It can hold enough wastewater generated in a single cleaning cycle, reducing the number of times it needs to be emptied. At the same time, the relatively forward position of the second housing 41 shifts the overall center of gravity of the floor brush assembly 100 further towards the cleaning component 20, increasing the pressure between the cleaning component 20 and the surface to be cleaned. The size ratio of the fan assembly 42 (D3 / D) is greater than or equal to 0.2 and less than or equal to 0.3. This ensures sufficient fan power while avoiding excessive space occupation, keeping the total length of the floor brush assembly 100 within a reasonable range and improving its maneuverability in narrow areas such as furniture gaps 13. Furthermore, the specific size ratio ensures even weight distribution of the floor brush assembly 100 in the front-to-back direction. The pressure generated by the front cleaning component 20 contacting the ground, the gravity of the middle housing, and the counterweight of the rear fan assembly 42 are balanced, allowing the cleaning component 20 to maintain a stable fit even on uneven surfaces.

[0103] In an alternative embodiment, please continue reading Figure 6 The total projected area of ​​the floor brush assembly 100 in the vertical direction is S, and the projected area of ​​the first housing 31 in the vertical direction is S1, where S1 / S is greater than or equal to 0.5 and less than or equal to 0.9; and / or, the projected area of ​​the second housing 41 in the vertical direction is S2, where S2 / S is greater than or equal to 0.2 and less than or equal to 0.5. The dimension of the first housing 31 in the vertical direction is H1, where H1 is greater than or equal to 14mm and less than or equal to 18mm; and / or, the dimension of the second housing 41 in the vertical direction is H2, where H1 / H2 is greater than or equal to 0.15 and less than or equal to 0.3.

[0104] In this embodiment, the ratio of the projected areas of the first housing 31 and the second housing 41 ensures that both housings have sufficient liquid storage and dirt collection area within a limited space, and the height ratio keeps the center of gravity at a low position. The first housing 31 has a larger projected area, allowing it to be designed to be thinner. This is because the first housing 31 can extend rearward above the cavity 12, utilizing the space above the cavity 12, thus making the floor brush assembly 100 smaller in the vertical direction. The second housing 41, within its limited projected area, is designed to be thicker to avoid insufficient dirt collection due to a small projected area. The combined ratio of the projected areas of the first and second housings 41 achieves efficient allocation of liquid storage and dirt collection space, maximizing the liquid supply and dirt collection functions of the floor brush assembly 100 despite its limited overall size.

[0105] Regarding center of gravity control, the height H1 of the first chamber 31 is less than 18mm, and the H1 / H2 ratio is greater than or equal to 0.15 and less than or equal to 0.3. This height configuration makes the first chamber 31 flatter. While the second chamber 41, as the main component for collecting wastewater, is relatively tall, its overall center of gravity remains low due to its reasonable projected area ratio and the gradual increase in wastewater during cleaning. This lower center of gravity makes the floor brush assembly 100 more stable during operation, reducing the likelihood of tipping over or wobbling when pushed. Furthermore, this proportional design optimizes liquid flow efficiency. The larger projected area of ​​the first chamber 31 results in a more uniform liquid distribution inside, allowing for a more stable delivery of cleaning fluid to the outlet 21 during supply, reducing supply fluctuations caused by uneven liquid distribution. The appropriate projected area and height ratio of the second chamber 41 ensures smooth wastewater flow inside, and, combined with the bottom connecting structure, accelerates the transfer of wastewater from the first chamber 4111 to the second chamber 4112, improving wastewater collection efficiency and reducing wastewater residue within the chamber.

[0106] Furthermore, the volume of the first chamber 31 is V1, and the volume of the second chamber 41 is V2, where V2 / V1 is greater than or equal to 0.6 and less than or equal to 0.9. In this embodiment, V2 is slightly smaller than V1 to accommodate the ratio of cleaning fluid consumption to wastewater generation, thus preventing wastewater overflow.

[0107] Example 2:

[0108] like Figure 2 ,and Figures 6 to 9As shown, the floor brush assembly 100 of this embodiment includes a base 10, a cleaning component 20, a liquid supply module, and a dirt collection module. The liquid supply module includes a first housing 31 mounted on the base 10. The dirt collection module includes a second housing 41 and a fan assembly 42. The fan assembly 42 is connected to the air outlet of the second housing 41, and the fan assembly 42 and the second housing 41 are arranged horizontally. The base 10 has a suction port 22 and a liquid outlet 21. The cleaning component 20 is mounted on the base 10, with the suction port 22 and the liquid outlet 21 facing the cleaning component 20. The first housing 31 is connected to the liquid outlet 21, and the second housing 41 is connected to the suction port 22. Both the first housing 31 and the second housing 41 are mounted on the base 10 and are stacked vertically. The projected area of ​​one of the first housing 31 and the second housing 41 in the vertical direction is larger than that of the other.

[0109] In this embodiment, the first tank 31 can store clean water or a cleaning solution mixed with cleaning agents, and supplies the solution to the cleaning component 20 through the outlet 21. The second tank 41 is connected to the suction port 22 and is used to store dirt, which may include sewage and solid impurities. When the surface cleaning equipment 1000 performs cleaning operations, the cleaning solution in the first tank 31 is evenly sprayed onto the cleaning component 20 or the surface to be cleaned through the outlet 21. The cleaning component 20 rubs the surface to be cleaned to remove stains, and at the same time, the dirt collection module generates negative pressure, sucking the sewage and solid impurities into the second tank 41 for storage through the suction port 22.

[0110] It is understandable that during the cleaning process, the mass of the first housing 31 gradually decreases due to liquid supply, while the mass of the second housing 41 gradually increases due to dirt collection. If the first housing 31 and the second housing 41 are arranged side by side in the horizontal direction, the center of gravity of the entire floor brush assembly 100 will continuously shift from the first housing 31 to the second housing 41 as the cleaning operation progresses. This is detrimental to the overall stability of the floor brush assembly 100, causing the cleaning component 20 to easily lift up locally, resulting in insufficient adhesion to the component to be cleaned. Furthermore, in this embodiment, the stacked arrangement of the first housing 31 and the second housing 41 makes the structure of the floor brush assembly 100 more compact and smaller in the horizontal direction. In particular, the reduction in the lateral dimension allows the surface cleaning device 1000 to reach deep into furniture crevices for cleaning, reducing cleaning dead angles.

[0111] Furthermore, the vertical layout design brings the center of gravity of the floor brush assembly 100 closer to the top of the cleaning component 20. The centers of gravity of the first housing 31 and the second housing 41 are highly aligned vertically, and the resultant force line of the floor brush assembly 100 is basically consistent with the support center line of the base 10. This more balanced and stable center of gravity enhances the pressure of the cleaning component 20 on the surface to be cleaned, allowing it to adhere more stably to the surface. In addition, the projected area of ​​the first housing 31 in the vertical direction is larger than that of the second housing 41, or vice versa. That is, the projections of the first housing 31 and the second housing 41 in the vertical direction do not completely overlap; one of them extends beyond the other in the horizontal direction. The space between them in the vertical direction can be used to install other components of the floor brush assembly. This design makes the floor brush assembly 100 more compact and smaller in size, allowing it to navigate low-lying areas, further reducing cleaning dead spots and improving cleaning effectiveness.

[0112] Furthermore, the fan assembly 42 is also integrated into the floor brush assembly and is laid horizontally alongside the second housing 41. Thus, the air duct connecting the second housing 41 and the fan assembly 42 no longer needs to extend upwards to the body of the surface cleaning device 1000, resulting in a shorter exhaust path and reducing the likelihood of malfunctions.

[0113] Based on the previous embodiment, please continue to refer to... Figures 6 to 9 A filter 43 (usually a HEPA filter) is also provided between the second housing 41 and the fan assembly 42. The filter 43 is detachably provided from the second housing 41. The second housing 41 is detachably installed on the base 10. When the second housing 41 is removed from the base 10, the filter 43 remains in the base 10.

[0114] In the prior art, the filter 43 is typically detachably installed on the second housing 41 (usually located on the open side of the upper end of the second housing 41). When the user needs to clean and maintain the sludge collection module, the second housing 41 needs to be removed from the base 10. At this time, dirt in the second housing 41 can easily splash out during the user's disassembly operation, contaminating the filter and thus adversely affecting the service life of the sludge collection module. In this embodiment, since the fan assembly 42 and the second housing 41 are laid flat in the horizontal direction, the filter 43 can be placed on the side of the second housing 41 in the horizontal direction. When the second housing 41 is disassembled, the filter 43 separates from the second housing 41, and the dirt in the second housing 41 will not contaminate the filter 43. This facilitates the user's disassembly operation of the second housing 41 and helps to extend the service life of the sludge collection module.

[0115] Preferably, the fan assembly 42 is located behind the second housing 41, and the air outlet of the fan assembly 42 extends through the rear side of the base 10. Preferably, the exhaust path of the fan assembly 42 extends from front to back, thus making the structure of the floor brush assembly 100 compact, and the exhaust air is led to the rear of the floor brush assembly 100 to avoid affecting the cleaning of the front. The fan assembly 42 also includes a filter 43, and the second housing 41, filter 43, and fan assembly 42 are arranged sequentially from front to back.

[0116] Optionally, the floor brush assembly 100 also includes a fan assembly 42 connected to the second housing 41. The air outlet of the fan assembly 42 faces the rear of the base 10. The cleaning component 20, the second housing 41, and the fan assembly 42 are arranged sequentially from front to back. This forms an efficient operating process. The cleaning component 20 directly acts on the surface to be cleaned in front. The second housing 41 promptly sucks away wastewater through the suction port 22 to prevent wastewater from spreading. When the fan assembly 42 operates, it creates a negative pressure inside the second housing 41 to suck up the wastewater. The exhaust air passes through the filter 43 and is discharged from the air outlet of the fan assembly 42 to the rear of the floor brush assembly 100. In this embodiment, the second housing 41, the filter 43, and the fan assembly 42 are arranged sequentially from front to back. On the one hand, this allows the exhaust air to be led to the rear of the base 10, avoiding affecting the cleaning in front. On the other hand, the structure is compact, the exhaust path is short, and it is less prone to failure.

[0117] Preferably, such as Figure 6 and Figure 11 As shown, the rear end of the first housing 31 extends beyond the second housing 41, and the rear end of the second housing 31 has a notch 311 extending vertically, in which the fan assembly 42 is at least partially accommodated. In this embodiment, the fan 42 is installed using the horizontally offset space between the first housing 31 and the second housing 41. The notch 311 also allows the fan assembly 42 to be designed to be taller, ensuring a negative pressure effect while preventing the protruding portion of the fan assembly 42 from overlapping the first housing 31 vertically. This also allows the first housing 31 to be made thinner, resulting in a more compact structure and smaller vertical dimensions for the floor brush assembly 100.
