Detailed Implementation

[0026] The related technology of household handheld floor cleaning equipment includes a cleaning fluid delivery system and a wastewater recovery system. The cleaning fluid in the supply tank is delivered to the roller brush through a pump and fluid distributor. The wet roller brush wipes the floor and the dirt is attached to the roller brush. The floor brush is equipped with a squeegee to squeeze the wastewater off the roller brush. The wastewater recovery system includes a suction port, a suction source connected to the suction port to generate working airflow, and a selectively removable recovery tank. The squeezed wastewater is delivered to the recovery tank through the suction port.

[0027] The charging base includes a tray on which the floor cleaning equipment is placed for self-cleaning. During self-cleaning, the roller brush is cleaned. Specifically, water is sprayed onto the roller brush during self-cleaning, and the roller brush rotates to perform self-cleaning. The wastewater after cleaning the roller brush is recycled to a recycling bin, thus completing the self-cleaning of the roller brush.

[0028] Related household floor cleaning devices cannot meet the needs of different application scenarios. Therefore, this application provides a novel floor cleaning device. Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] As shown in Figure 1, the floor cleaning equipment 100 according to an embodiment of this application includes a body 10, a waste liquid holding assembly 20, a handheld vacuum cleaner 30, a clean water holding assembly 40, and a cleaner head assembly 50. The cleaner head assembly 50 is connected to the body 10. The waste liquid holding assembly 20 is connected to the cleaner head assembly 50, and the handheld vacuum cleaner 30 is connected to the waste liquid holding assembly 20. The handheld vacuum cleaner 30 is configured to be detachable from the body 10 and used independently. The floor cleaning equipment 100 of this application can meet the cleaning needs of multiple scenarios, eliminating the need to purchase different machines separately.

[0030] Furthermore, the direction of travel when the machine body 10 is pushed is forward. The waste liquid containing component 20 is located at the rear of the machine body 10, the handheld vacuum cleaner 30 is located at the rear of the machine body 10, and the clean water containing component 40 is located at the front of the machine body 10. In this application, the waste liquid containing component 20 is located at the rear of the machine body 10 to facilitate wastewater discharge after docking with the base station; the clean water containing component 40 and the waste liquid containing component 20 are located on opposite sides of the machine body 10, resulting in a more even weight distribution of the ground cleaning equipment 100 and easier operation.

[0031] In some embodiments, the floor cleaning equipment 100 has a first operating mode and a second operating mode.

[0032] As shown in Figures 1 to 3, in the first working mode, the handheld vacuum cleaner 30 is connected to the body 10. The handheld vacuum cleaner 30 is configured to drive the mixed fluid to flow sequentially from the suction port of the cleaner head assembly 50 through the cleaner head assembly 50, the waste liquid container assembly 20 and the handheld vacuum cleaner 30, and to discharge the clean air after the mixed fluid has been filtered from the exhaust port of the handheld vacuum cleaner 30. The first working mode can be a dry and wet dual-use upright vacuuming mode: the handheld vacuum cleaner 30 is connected to the body 10, and under the suction of the handheld vacuum cleaner 30, the mixture of gas, dust and / or liquid flows from the suction port of the cleaner head assembly 50 through the cleaner head assembly 50, the connecting channel and the dirty liquid container assembly 20 for primary separation and filtration, realizing the separation of dust and / or liquid. The dust and / or liquid are stored in the dirty liquid container assembly 20. The fluid after the first stage of separation enters the dust cylinder assembly of the handheld vacuum cleaner 30 from the upper part of the dirty liquid container assembly 20 through the through hole on the body 10 for the second stage of dust and gas separation. The separated clean air is discharged from the exhaust port of the handheld vacuum cleaner 30.

[0033] As shown in Figure 5, in the second working mode, the handheld vacuum cleaner 30 is detached from the main body 10 and used independently. The handheld vacuum cleaner 30 is configured to drive the mixed fluid into the handheld vacuum cleaner 30 through its air inlet 33, and to allow the filtered clean air to be discharged from the exhaust port of the handheld vacuum cleaner 30. The second working mode is the handheld vacuuming mode: the handheld vacuum cleaner 30 is unlocked and detached from the main body 10 and used independently. Under the suction of the handheld vacuum cleaner 30, the fluid enters the dustbin assembly through the air inlet 33 for dust-air separation, and the separated clean air is discharged from the exhaust port of the handheld vacuum cleaner 30. The separation inside the dustbin includes two stages: the first stage is a porous filter, and the second stage is multiple multi-cone filters 311. In addition, Figure 4 is a schematic diagram of the floor cleaning equipment after the handheld vacuum cleaner 30 is removed.

[0034] In some embodiments, as shown in Figure 2, the wastewater containing assembly 20 includes a first-stage filter assembly 21, which is configured to filter the fluid flowing through the wastewater containing assembly 20. The wastewater containing assembly 20 can filter the mixed fluid during floor cleaning operations such as floor cleaning by the floor cleaning equipment 100, retaining dust, water, etc., in the mixed fluid within the wastewater containing assembly 20, and directing clean airflow to the handheld vacuum cleaner 30, thereby improving filtration efficiency. Additionally, it prevents water collected during the floor cleaning process from flowing into the handheld vacuum cleaner 30, thus affecting its use. The lower end of the wastewater containing assembly 20 has a fluid inlet 201, which communicates with the cleaner head assembly 50. A flexible hose 60 can be provided between the cleaner head assembly 50 and the fluid inlet 201. The mixed fluid can enter the cleaner head assembly 50 through the inlet and then flow through the hose 60 to the fluid inlet 201, thus entering the wastewater containing assembly 20 for filtration.

[0035] Specifically, as shown in Figure 2, the wastewater containing assembly 20 is provided with a guide pipe 22, and the first-stage filtration assembly 21 may include structures such as a baffle 211 and a first filter element 212. The inlet of the guide pipe 22 is connected to the fluid inlet 201, and the first filter element 212 is disposed around the outlet end of the guide pipe 22. The baffle 211 is opposite to the outlet of the guide pipe 22 and guides the flow towards the first filter element 212 along the outlet direction of the guide pipe 22. During use, the mixed fluid enters the guide pipe 22 through the fluid inlet 201 and flows along the guide pipe 22. After exiting the guide pipe 22 from the outlet, it is blocked by the baffle 211. The solid and liquid waste in the mixture will be blocked by the baffle 211 and then fall to the first filter element 212. The solid waste will remain in the first filter element 212, and the liquid waste will be filtered by the first filter element 212 and then remain in the wastewater containing assembly 20. In addition, the gas in the mixed fluid will bypass the baffle 211 and flow to the outlet of the waste liquid containing assembly 20. A second filter element 23 can be provided at the outlet of the waste liquid containing assembly 20. The gas in the mixed fluid will be filtered by the second filter element 23 and then sent out of the waste liquid containing assembly 20.

[0036] Additionally, as shown in Figure 6, the handheld vacuum cleaner 30 includes a second-stage filter assembly 31 and an airflow drive assembly. The airflow drive assembly may include a motor. The second-stage filter assembly 31 is configured to filter the fluid flowing through the handheld vacuum cleaner 30, and the airflow drive assembly is configured to drive the fluid. In the aforementioned first state, the filtration effect on the mixed fluid can be optimized through the cooperation of the first-stage filter assembly 21 and the second-stage filter assembly 31. Furthermore, the filtration pressure of the second-stage filter assembly 31 can be reduced by the first-stage filter assembly 21 filtering the mixed fluid, thereby improving the filtration effect. In the second state, the second-stage filter assembly 31 can be configured to filter the mixed fluid independently. That is, the handheld vacuum cleaner 30 can be used alone, with the fluid filtered through the second-stage filter assembly 31, making it suitable for different scenarios. Of course, in other embodiments, the liquid is collected by the waste liquid containing component 20, and the airflow enters the handheld vacuum cleaner 30 for dust and air separation. In this case, no liquid enters the handheld vacuum cleaner 30. The handheld vacuum cleaner 30 is mainly used for filtering dry airflow and does not handle liquid dirt. This simplifies the design of the handheld vacuum cleaner 30, reduces costs, and avoids the handheld vacuum cleaner 30 from filtering wet waste, which would make the situation too dirty and not conducive to cleaning, thus improving the user experience.

[0037] In some embodiments, as shown in FIG6, the handheld vacuum cleaner 30 includes a first handle 36, which facilitates the use of the handheld vacuum cleaner 30. In addition, by providing the first handle 36, the use of the handheld vacuum cleaner 30 can be facilitated, avoiding the problem of not being able to find the handle when the handheld vacuum cleaner 30 needs to be used.

[0038] Optionally, as shown in Figure 6, the handheld vacuum cleaner 30 includes an air inlet 33, a motor 34, a battery 35, and a first handle 36 arranged sequentially along the axial direction. The handheld vacuum cleaner 30 has a rechargeable battery 35 and a motor 34. The motor 34 provides negative pressure, and the battery 35 provides power, eliminating the need for separate motors 34 and batteries 35, saving costs, optimizing the structural layout, and indirectly enabling product miniaturization. The air inlet 33, filter, motor 34, battery 35, and first handle 36 are arranged sequentially along the axis of the handheld vacuum cleaner 30, resulting in a compact component layout and making the linear design more convenient to use. The handheld vacuum cleaner 30 can be used independently, making it suitable for more application scenarios. Additionally, a multi-cone filter 311 and a pre-motor filter 312 are provided between the air inlet 33 and the motor 34. Additionally, the handheld vacuum cleaner 30 includes a housing, a second-stage filter assembly 31 and an airflow drive assembly disposed within the housing, an air inlet 33 disposed at one end of the housing, and a first handle 36 disposed at the other end of the housing. The second-stage filter assembly 31 includes a multi-cone filter 311 and a motor pre-filter 312, and the airflow drive assembly includes a motor 34.

[0039] Optionally, the handheld vacuum cleaner 30 is positioned above the waste liquid containing assembly 20. The body 10 is provided with a connection interface 101 for connecting the air inlet of the handheld vacuum cleaner 30. The air inlet of the handheld vacuum cleaner 30 is inserted into the connection interface 101 and communicates with the waste liquid containing assembly 20.

[0040] In some embodiments, as shown in Figures 1 to 4, the body 10 includes a body 11 and a second handle 12. The lower end of the body 11 is connected to the cleaner head assembly 50, and the upper end of the body 11 is connected to the second handle 12. The waste liquid holding assembly 20 and the handheld vacuum cleaner 30 are located on the rear side of the body 11, and the clean water holding assembly 40 is located on the front side of the body 11.

[0041] This application provides a multi-functional vacuum cleaner that combines floor vacuuming, floor cleaning, and handheld vacuuming, including a body 11, a second handle 12, a handheld vacuuming device 30, a waste liquid holding assembly 20, a clean water holding assembly 40, and a cleaning head assembly 50. A protruding mounting base can be designed at the rear of the body 11; the handheld vacuuming device 30 is positioned above the mounting base and can be detached or mounted separately on the body 11; the waste liquid holding assembly 20 is positioned below the mounting base and can be detached or mounted separately on the body 11. The mounting base has a through hole for fluid to enter the handheld vacuuming device 30 through the waste liquid holding assembly 20. The handheld vacuuming device 30 and the waste liquid holding assembly 20 are respectively detachably and sealingly connected to the top and bottom of the through hole, improving the installation stability of the handheld vacuuming device, ensuring the sealing of the fluid connection point of the vacuuming device, and facilitating the user's disposal of waste in the waste liquid holding assembly 20, thereby improving the user experience.

[0042] When operating the vacuum cleaner, a handheld vacuum cleaner 30 and a waste collection assembly 20 must be installed. The handheld vacuum cleaner 30 provides suction power to pick up dirt, and the waste collection assembly 20 stores at least partially the dirt that has been sucked up. The handheld vacuum cleaner 30 can be any type of cordless handheld vacuum cleaner (e.g., a portable vacuum), and includes a dustbin assembly and a power assembly. When the handheld vacuum cleaner 30 is detached, it can be used in scenarios where the floor cleaning equipment 100 is not suitable (e.g., where the space is small or the surface to be cleaned is easily contaminated). The detachable waste collection assembly 20 facilitates the handling of dirt without requiring the removal of additional parts during cleaning, ensuring ease of use.

[0043] The fluid in this application can be a clean airflow or an airflow carrying contaminants; the contaminants are at least one of dust, solid contaminants (such as cigarette butts, paper scraps, rice grains, etc.), and liquid contaminants (such as orange juice, dirty water, egg liquid, etc.).

[0044] Understandably, in wet / dry upright vacuum cleaner mode, the waste liquid containing component 20 constitutes the first separation structure; as the airflow carrying dirt flows through the waste liquid containing component 20, the dirt, solid dirt, and dust contained therein can be intercepted and stored in the waste liquid containing component 20. Due to the small size and light weight of dust and gas-liquid (gas droplets), they are inevitably guided to the dustbin assembly along with the airflow; thus, the dustbin assembly constitutes the second separation structure. If the airflow entering the dustbin assembly carries dirt, the dustbin assembly can separate the dust and gas, intercept and store the dirt in the dustbin assembly, and guide the airflow to the power component for discharge.

[0045] Furthermore, the cleaner head assembly 50 and the waste liquid container assembly 20 are fluidly connected via a connecting channel. This connecting channel can be located within the body 11, thus ensuring that the fluid inlet 201 of the waste liquid container assembly 20 is not limited to being located at the bottom. In some embodiments, a connecting channel is provided between the bottom of the waste liquid container assembly 20 and the cleaner head assembly 50, allowing mixed fluid to flow from the cleaner head assembly 50 into the waste liquid container assembly 20.

[0046] In addition, the waste liquid containing assembly 20 includes a waste liquid inlet channel, the inlet of which is located at the bottom, side, or top of the waste liquid containing assembly 20. All of these configurations enable the fluid to enter the waste liquid containing assembly 20 for primary separation of gas, dust, and / or liquid during vacuuming.

[0047] Optionally, a cyclone separator is provided inside the wastewater containing assembly 20 so that after the mixed fluid enters the wastewater containing assembly 20, the gas, dust and / or liquid are centrifugally separated. The dust and / or liquid are stored at the bottom of the wastewater containing assembly 20, and the separated gas flows out from the middle upwards. The cyclone separator can be any type of separator capable of centrifugal separation in the prior art, and is not limited in this application.

[0048] Furthermore, the body 11 is rod-shaped, having a lower end and an upper end; the lower end is configured as a floor brush connection end for pivotally connecting to the cleaner head assembly 50, and the upper end is configured as a handle connection part for detachably inserting the second handle 12.

[0049] This solution minimizes the support area requirement for the body 11. The body 11 can be constructed as a slender rod, reducing the overall weight of the body 11. Compared with existing technologies, the overall weight of the body 11 can be reduced by more than 70%, and the overall appearance of the machine is more concise and elegant.

[0050] To improve the stability of the vertical floor cleaning equipment 100, a support base is provided at the bottom of the body 10, and the sewage container 20 is supported on the body 10 by the support base.

[0051] In this application, the body 10 is provided with a first locking structure for independently locking / unlocking the handheld vacuum cleaner 30; and / or, the body 10 is provided with a second locking structure for independently locking / unlocking the waste liquid containing assembly 20. In wet and dry mode, the handheld vacuum cleaner 30 can be fixed to the mounting base and the body 11 by the first locking structure, and the waste liquid containing assembly 20 can be fixed to the mounting base, the waste liquid containing assembly 20 support base, and the body 11 by the second locking structure. This achieves that both the handheld vacuum cleaner 30 and the waste liquid containing assembly 20 can be detached and fixed independently; wherein, the first locking structure and the second locking structure can adopt locking structures, snap-fit ​​structures, etc., which are well known to those skilled in the art, and are not further limited in this application.

[0052] In this application, the support base of the waste liquid containing assembly 20 is pivotable relative to the body 11; when the second locking structure is unlocked, the support base of the waste liquid containing assembly 20 can automatically rotate relative to the body 11, thereby driving the waste liquid containing assembly 20 to a conveniently accessible state. Specifically, the support base of the waste liquid containing assembly 20 is constructed as a swing structure, through which the waste liquid containing assembly 20 automatically swings out relative to the body 11; the swing structure includes an interface component and a connector component, the interface component is disposed on one of the waste liquid containing assembly 20 and the body 11, and the connector component is disposed on the other; the swing structure also includes an elastic component, when the interface component is disposed on the body 11, the elastic component applies force between the interface component and the body 11 to bounce one end of the interface component away from the body 11; when the connector component is disposed on the body 11, the elastic component applies force between the connector component and the body 11 to bounce one end of the connector component away from the body 11; furthermore, it can be linked to swing out the waste liquid containing assembly 20.

[0053] The three-in-one wet and dry multi-functional floor cleaning device 100 in this application also includes a connecting pipe and a brush head, which are used to connect with the handheld vacuum cleaner 30 when the handheld vacuum cleaner is used alone; wherein, the connecting pipe includes a hose, a long connecting pipe, etc., and the brush head includes a mite removal brush, a flat brush, a bristle brush, a pet brush, etc.

[0054] Understandably, when the handheld vacuum cleaner 30 is used alone, it can be used directly or connected to accessories such as mite removal brushes, flat brushes, bristle brushes, and pet brushes. It can also be connected to accessories such as hoses and long extension tubes, thus enabling whole-house cleaning in various scenarios.

[0055] In this application, the second handle 12 can be used as a long extension tube in combination with the handheld vacuum cleaner 30, which can reduce the space occupied by the accessories and reduce the cost of the accessories.
