Description

Technical Field

[0001] This utility model belongs to the field of cleaning products, specifically relating to cleaning components, devices and systems capable of vacuuming and mopping. Background Technology

[0002] Vacuum cleaners are now widely used in daily life, providing users with efficient and convenient cleaning services. While vacuum cleaners can remove loose dust from the floor, they struggle with stubborn stains that are stuck to the surface. Users then need to use a mopping device with a wet mopping function to wet and wipe away the stains after vacuuming. This requires users to operate both dry vacuuming and wet mopping devices separately, resulting in repetitive work, high time costs, and an inability to meet the pace of modern life.

[0003] To address these issues, engineers have developed a combined dry and wet cleaning device that can simultaneously perform dry vacuuming and wet mopping in a single operation. For example, Chinese invention patent CN106455880B discloses a floor cleaning device that connects a detachable wet cleaning unit to a floor brush. The detachable wet cleaning unit includes a water tank and a mop. The mop is installed at the bottom of the water tank, and a nozzle sprays cleaning fluid onto the mop below, wetting it. The mop then wipes away stains, achieving dry vacuuming with the brush and wet mopping with the mop. Chinese utility model patent CN217218916U discloses a vibrating cleaning component and vacuum cleaner. Water is introduced through a perforation hole onto the cleaning section (cleaning cloth) below, and then the stains are wiped away, similarly achieving dry vacuuming with the brush and wet mopping with the cloth.

[0004] Because these methods involve first wetting the cloth underneath before wiping the stains, initially, only the top surface of the cloth absorbs water, leaving the area in contact with the ground dry and unable to wet the stains. This makes it difficult to clean the stains. Even after the bottom surface of the cloth is wetted, effectively wetting the stains, the entire thickness of the cloth is already wetted, while the top surface continues to wet. This can lead to excessive water in the cloth, making it difficult to absorb more wastewater / stains, resulting in incomplete cleaning and potentially leaving even more water residue on the ground. Summary of the Invention

[0005] This invention was developed to solve the above-mentioned problems, and aims to provide a cleaning component, device, and system that can effectively achieve dry suction and wet mopping, and extend the effective cleaning time for wiping the surface to be cleaned.

[0006] <Component>

[0007] This utility model provides a cleaning component, including: a floor brush, comprising: a roller brush, and a cleaning opening exposing the roller brush toward the surface to be cleaned; and a wet cleaning unit, detachably connected to the floor brush, comprising: a liquid storage unit for storing cleaning liquid, a spray unit connected to the liquid storage unit for spraying onto the surface to be cleaned, and a mounting plate located at the bottom of the liquid storage unit; wherein, the bottom surface of the mounting plate is provided with a mop-covered area that is covered (blocked) by the mop after the mop is installed; the nozzle of the spray unit is located between the cleaning opening and the mop-covered area.

[0008] The beneficial effects of the above scheme are:

[0009] When using this cleaning component to clean a surface, the floor brush first absorbs dry dust (dust, particles, hair, and other dirt) from the surface, initially cleaning it before spraying it with water from the nozzle. Then, the mop behind it wipes the surface, effectively achieving both dry suction and wet mopping. Furthermore, the nozzle doesn't spray directly onto the mop; instead, it sprays directly at the surface stains. The lower surface of the mop only absorbs moisture upon contact with the sprayed surface. This ensures efficient wetting of stains without over-wetting the mop. After the lower surface absorbs moisture, the upper layer continues to absorb moisture, effectively and continuously absorbing wastewater / stains to clean the surface. Therefore, the effective cleaning time for the mop to clean the surface is extended. In addition, the spray evenly wets the surface area without over-wetting it.

[0010] Preferably, in the cleaning assembly provided by this invention, the nozzle is located between the rear edge of the floor brush and the front edge of the mop coverage area / mop, or the nozzle is closer to the rear edge of the floor brush than the front edge of the mop coverage area / mop. This design keeps the nozzle away from the cleaning opening, thereby reducing the amount of moisture drawn into the floor brush.

[0011] Preferably, in the cleaning assembly provided by this utility model, the distance from the center of the nozzle to the leading edge of the mop is a~3a, where a≥5mm, and the diameter D of the nozzle ≤a-2mm. This design keeps the nozzle away from the cleaning opening, minimizing the amount of moisture sucked in by the floor brush.

[0012] Preferably, in the cleaning assembly provided by this invention, the nozzle sprays downwards onto the surface to be cleaned. This design allows the spray to more effectively wet the stains on the floor and minimizes the risk of the spray being sucked in by the floor brush.

[0013] Preferably, in the cleaning assembly provided by this utility model, the spray unit has two nozzles, respectively located on the left and right sides of the front side of the mounting plate. The front side of the mounting plate is located in front of the mop coverage area and closer to the rear edge of the floor brush relative to the mop coverage area. This design allows the surface area to be cleaned to be sprayed more evenly, covering a larger area and cleaning more efficiently.

[0014] Preferably, in the cleaning assembly provided by this utility model, the floor brush includes a rear wheel that protrudes from the center of the mounting plate, and this protruding area is not part of the mop coverage area. This design not only allows the cleaning assembly to be effectively supported by the rear wheel, but also makes the cleaning assembly easier to move on the surface to be cleaned.

[0015] Preferably, in the cleaning assembly provided by this utility model, the liquid storage unit and the mounting plate each have two protruding holes in their middle portions, allowing the two rear wheels to extend from the bottom of the wet cleaning section. This design not only ensures that the cleaning assembly is evenly supported by the rear wheels, but also makes the cleaning assembly easier to move on the surface to be cleaned.

[0016] Preferably, in the cleaning assembly provided by this utility model, the wet cleaning unit further includes a mop, which is detachably mounted on the mounting plate. An opening is provided on the mop corresponding to the rear wheel, allowing the rear wheel to extend and contact the ground. This design not only ensures that the cleaning assembly is evenly supported by the rear wheel, but also makes the cleaning assembly easier to move across the surface to be cleaned.

[0017] In addition, in the cleaning assembly provided by this utility model, the mounting plate can be integrally formed with the liquid storage unit, or the mounting plate can be part of the bottom of the liquid storage unit.

[0018] <device>

[0019] Furthermore, this utility model also provides a cleaning device, including: a cleaning component described in any of the above <components>; and a vacuum cleaner body having a negative pressure source for generating negative pressure and a ventilation duct for transmitting negative pressure outward; wherein the floor brush of the cleaning component is detachably matched and connected to the ventilation duct. This cleaning device includes the <components> mentioned above, and therefore has the same beneficial effects as the <components> described above.

[0020] <System>

[0021] Furthermore, this utility model also provides a cleaning system, including: a cleaning device described in any of the above <components>; and a cleaning base station, at least for storing the cleaning device. This cleaning system includes the <components> mentioned above, and therefore has the same beneficial effects as the <components> described above. Attached Figure Description

[0031] The specific implementation scheme of the cleaning component involved in this utility model will be described in detail below with reference to the accompanying drawings.

[0032] <Example>

[0033] like Figures 1-4 As shown, the cleaning assembly 1000 is used to simultaneously (in the same process) perform dry vacuuming and wet mopping cleaning of the surface to be cleaned in a single operation. The cleaning assembly 1000 includes a floor brush 10 and a wet cleaning section 20.

[0034] The floor brush 10 is used in conjunction with the ventilation duct of the vacuum cleaner body to agitate dust (fine dust, hair, and other dirt) on the surface to be cleaned (e.g., the floor), and uses the negative pressure transmitted from the ventilation duct to send the dust into the dust cup of the vacuum cleaner body. The floor brush 10 includes a floor brush housing 11, a roller brush 12, a cleaning opening 13, a power supply unit 14, an air outlet 15, and two rear wheels 16. The floor brush housing 11 is used to mount the roller brush 12, the power supply unit 14, the air outlet 15, and the rear wheels 16. The roller brush 12 is rotatably mounted in the mounting cavity formed by the floor brush housing 11, and can agitate the surface to be cleaned. The cleaning opening 13 is opened on the bottom surface of the floor brush housing 11, allowing the roller brush 12 to protrude towards the surface to be cleaned. The power supply unit 14 is electrically connected to the ventilation duct of the vacuum cleaner body, and the power supply unit 14 includes two power supply pins 141, which can supply current transmitted from the vacuum cleaner body to the wet cleaning section 20. The exhaust duct 15 extends from the rear of the floor brush housing 11, with its front end connected to the mounting cavity and its rear end used to connect to the ventilation duct of the vacuum cleaner body. The two rear wheels 16 are installed on the left and right sides of the rear end of the floor brush housing 11.

[0035] like Figures 1-9 As shown, the wet cleaning unit 20 is detachably mounted on the rear side of the floor brush 10, and it includes a liquid storage unit 21, a mounting plate 22, a spray unit 23, and at least one mop 24.

[0036] The liquid storage unit 21 is detachably connected to the rear area of ​​the floor brush 10. The interior of the liquid storage unit 21 is hollow and used to store cleaning liquid. The cleaning liquid can be water or other cleaning agents used to clean floors, carpets, and other surfaces. In this embodiment, the liquid storage unit 21 has two main housings 211 located on the left and right sides, a connecting body 212 located in the middle connecting the two main housings 211, and a cover 213 covering the main housings 211. The cover 213 is detachably and closably mounted on one of the main housings 211. Opening the cover 213 exposes the injection hole, thereby injecting cleaning liquid into the liquid storage unit 21 or draining residual liquid from the liquid storage unit 21.

[0037] Mounting plate 22 detachably connects the liquid storage unit 21 to the rear area of ​​the floor brush 10. The main body of mounting plate 22 forms the bottom of the liquid storage unit 21. A mop cover area 221 is provided on the bottom surface of mounting plate 22, which is covered by the mop 24 after the mop 24 is installed. "Covering" means blocking the surface to be cleaned from the mop cover area 221, preventing the mop cover area 221 from directly facing the surface. The mop cover area 221 has multiple Velcro adhesive sub-areas 221a, each with a hook surface that can detachably and securely attach to the looped surface of the mop 24. The front of mounting plate 22 is also equipped with two magnetic pieces 222, which can be used with... Figure 6 The iron plates 18 provided on the bottom rear end of the brush housing 11 are magnetically attracted and detachably fixed to each other, thereby connecting the entire wet cleaning section 20 to the brush 10 and enabling stable synchronous cleaning with the brush 10. Alternatively, the iron plates 18 can be installed on the mounting plate 22 and the magnetic plates 222 can be installed on the brush housing 11, which can also be detachably fixed by magnetic attraction.

[0038] For each of the two rear wheels 16, there are two protrusion holes 223 in the middle of the liquid storage unit 21 and the mounting plate 22, allowing the two rear wheels 16 to protrude / expose from the bottom of the wet cleaning section 20. The area on the mounting plate 22 where the rear wheels 16 are exposed (the area where the protrusion holes 223 are located) is not part of the mop coverage area 221.

[0039] The spray unit 23 is mounted on the mounting plate 22 and connected to the liquid storage unit 21 for spraying onto the surface to be cleaned. The spray unit 23 includes two atomizers 231 and 231, two metal pillars 232, and a switch 233.

[0040] Two atomizers 231 correspond to the left and right main housings 211, respectively, and are located at the bottom of the left and right main housings 211. Each atomizer 231 has a nozzle 231a (a spray area containing multiple micropores), which protrudes from the bottom of the mounting plate 22 and sprays directly downwards toward the surface to be cleaned. Figures 2-3As shown, nozzle 231a is located between cleaning opening 13 and mop coverage area 221 / mop 24, which is the horizontal positional relationship; while from the vertical direction, there is no obstruction / covering below nozzle 231a, and nozzle 231a sprays directly onto the surface to be cleaned.

[0041] Two metal posts 232 correspond to two power supply springs 141 respectively, and are used to supply the current transmitted from the vacuum cleaner body to the atomizer 231. When the wet cleaning part 20 is assembled to the floor brush 10, the two metal posts 232 are electrically connected to the two power supply springs 141 respectively.

[0042] The atomizing switch 233 is installed on the floor brush 10 and connected to the power supply unit 14. When the user steps on the atomizing switch 233, the spray unit 23 is powered on and sprays. When the user steps on it again, the spray unit 23 is powered off and stops spraying.

[0043] like Figures 1-2 As shown in Figures 7 and 8, the mop 24 is detachably mounted on the bottom of the mounting plate 22. In this embodiment, the mop 24 is attached by matching the hook surface on the adhesive sub-area 221a with the loops on its upper surface, thereby covering the mop coverage area 221 on the mounting plate 22, but not covering the nozzle 231a located outside the mop coverage area 221. That is, the nozzle 231a is not blocked by the mop 24 and sprays downwards onto the ground, rather than spraying onto the mop 24. An exposed opening 241 is provided on the mop 24 corresponding to the rear wheel 16, so that the rear wheel 16 can extend / expose and contact the ground.

[0044] In this embodiment, two nozzles 231a are respectively located on the left and right sides of the front side of the mounting plate 22. The front side of the mounting plate 22 is located in front of the mop coverage area 221, and is the side of the mounting plate 22 that is closer to the rear edge 17 of the floor brush 10 relative to the mop coverage area 221. The nozzles 231a are located between the rear edge 17 of the floor brush 10 and the front edge 242 of the mop coverage area 221 / mop 24, or in other words, the nozzles 231a are closer to the rear edge 17 of the floor brush 10 relative to the front edge 242 of the mop coverage area 221 / mop 24. Here, "closer" refers to a shorter straight-line distance along the direction perpendicular to the rotation axis of the roller brush 12 (horizontal direction). The rear edge 17 represents the junction between the bottom surface of the floor brush 10 (the floor brush housing 11 closest to the bottom surface) and the wet cleaning section 20. Figure 3 As shown, let L1 be the straight-line distance from the center of the nozzle 231a to the rear edge 17 of the floor brush 10, and L2 be the straight-line distance from the front edge 242 of the mop coverage area 221 / mop 24 to the rear edge 17 of the floor brush 10. Then L1 < L2. In this embodiment, the nozzle 231a is circular with a diameter D = 8 mm; L1 = 17 mm, L2 = 37 mm, and the width of the bottom surface of the mounting plate 22 is L3 = 100 mm.

[0045] The cleaning component 1000 described above can be used as part of a cleaning device in conjunction with the vacuum cleaner body. The cleaning device can also be part of a cleaning system, used in conjunction with a cleaning base station.

[0046] like Figures 1-9 As shown, based on the above structure, the specific working process of the cleaning component 1000 provided in this embodiment is as follows:

[0047] 1) Cleaning

[0048] The user connects the air outlet 15 of the floor brush 10 to the ventilation duct of the vacuum cleaner body, then places the cleaning component 1000 on the surface to be cleaned, turns on the vacuum cleaner body, and the roller brush 12 rotates to agitate the surface dust. At the same time, the negative pressure transmitted from the cleaning opening 13 draws the dust into the vacuum cleaner body. The user turns on the atomizer 231 by stepping on the atomizing switch 233, and the nozzle 231a begins to spray onto the surface to be cleaned, starting the dry and wet simultaneous vacuuming and mopping process. When the user pushes the cleaning component 1000 to area A of the surface to be cleaned, the floor brush 10 first sucks up the dry dust (dust, particles, hair, and other dirt) in area A, initially cleaning area A. As the user pushes, the nozzle 231a is moved to spray towards area A, wetting the stubborn stains on area A that were not sucked into the floor brush 10. Then, the mop 24 behind it is moved to area A to wipe and suck up the stubborn stains and dirty water, thus realizing the dry vacuuming and wet mopping process of area A. The same applies to other areas of the surface to be cleaned; as the user moves the cleaning component 1000 to these areas, the dry vacuuming and wet mopping processes can be performed simultaneously (in the same stroke / process).

[0049] 2) Disassembly and assembly of wet cleaning unit 20

[0050] When the user does not need to use wet mopping or needs to remove and replenish cleaning solution, the user can press down the water tank from the top of the water tank with one foot / hand, while lifting the floor brush 10 air outlet 15 with the other hand (including by lifting the vacuum cleaner body or ventilation duct), and the two can be separated by overcoming the magnetic attraction between the wet cleaning part 20 and the floor brush 10, and the wet cleaning part 20 can be removed.

[0051] Conversely, when the wet cleaning unit 20 needs to be installed, the user can place the floor brush 10 on the water tank from top to bottom with one hand, so that the iron plate 18 on the floor brush 10 corresponds to and is close to the magnetic plate 222 on the mounting plate 22, so that the magnetic attraction effect can be generated to install it in place.

[0052] 3) Disassembling and assembling the mop 24

[0053] Before mopping, attach the mop to the bottom of the water tank with Velcro, exposing the nozzle 231a and the rear wheel 16. After mopping, tear the mop cloth 24 off the bottom of the tank.
