The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figure 1According to the floor cleaning device 100 of the embodiment of the utility model, it includes a body 10, a dirty liquid containing assembly 20, a handheld vacuum device 30, a clean water containing assembly 40 and a cleaner head assembly 50, and the cleaner head assembly 50 is connected to the body 10. The dirty liquid containing assembly 20 is connected to the cleaner head assembly 50, and the handheld vacuum device 30 is connected to the dirty liquid containing assembly 20, and the handheld vacuum device 30 is configured to be detachable from the body 10 and used separately. The floor cleaning device 100 in the utility model can meet the cleaning needs of multiple scenes without the need to purchase different machines separately.

[0027] In addition, the moving direction of the machine body 10 when pushed is the front of the machine body 10, wherein the dirty liquid containing assembly 20 is arranged at the rear side of the machine body 10, the handheld vacuum device 30 is arranged at the rear side of the machine body 10, and the clean water containing assembly 40 is arranged at the front side of the machine body 10. In the present utility model, the dirty liquid containing assembly 20 is arranged at the rear of the machine body 10, which is convenient for sewage discharge after docking with the base station; the clean water containing assembly 40 and the dirty liquid containing assembly 20 are arranged at two opposite sides of the machine body 10, and the weight of the floor cleaning device 100 is relatively uniform, which is convenient for operation.

[0028] In some embodiments, the floor cleaning device 100 has a first working mode and a second working mode.

[0029] like Figures 1 to 3 In the first working mode, the handheld vacuum cleaner 30 is connected to the body 10, and the handheld vacuum cleaner 30 is configured to drive the mixed fluid to flow from the suction port of the cleaner head assembly 50 through the cleaner head assembly 50, the dirty liquid containing assembly 20 and the handheld vacuum cleaner 30 in sequence, and the clean air after the mixed fluid is filtered is discharged from the exhaust port of the handheld vacuum cleaner 30. The first working mode can be a wet and dry dual-purpose upright vacuuming mode: the handheld vacuuming device 30 is connected to the body 10, and under the suction of the handheld vacuuming device 30, a mixed fluid 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 containing assembly 20 in sequence, and then enters the handheld vacuuming device 30 for primary separation and filtration to achieve separation of dust and / or liquid. The dust and / or liquid are stored in the dirty liquid containing assembly 20. The fluid after the first stage of separation passes from the upper part of the dirty liquid containing assembly 20 through the through hole on the body 10 and enters the dust cylinder assembly of the handheld vacuuming device 30 for second stage dust and gas separation. The separated clean air is discharged from the exhaust port of the handheld vacuuming device 30.

[0030] like Figure 5In the second working mode, the handheld vacuum cleaner 30 is separated from the body 10 and used alone. The handheld vacuum cleaner 30 is configured to drive the mixed fluid into the handheld vacuum cleaner 30 through the air inlet 33 of the handheld vacuum cleaner 30, and to discharge the clean air after filtering the mixed fluid from the exhaust port of the handheld vacuum cleaner 30. The second working mode is the handheld vacuum mode: the handheld vacuum cleaner 30 is unlocked and separated from the body 10 and used alone. Under the suction of the handheld vacuum cleaner 30, the fluid enters the dust cylinder assembly through the air inlet 33 of the handheld vacuum cleaner 30 for dust and gas separation, and the separated clean air is discharged from the exhaust port of the handheld vacuum cleaner 30. The separation in the dust cylinder includes two stages, the first stage is a porous filter, and the second stage is a plurality of multi-cone filters 311. In addition, Figure 4 It is a schematic diagram of the floor cleaning device after the handheld vacuum device 30 is removed.

[0031] In some embodiments, such as Figure 2 , the dirty liquid containing assembly 20 includes a first-stage filter assembly 21, and the first-stage filter assembly 21 is configured to filter the fluid flowing through the dirty liquid containing assembly 20. The dirty liquid containing assembly 20 can filter the mixed fluid when the floor cleaning device 100 is performing floor cleaning or other working conditions, so as to leave the dust, water, etc. in the mixed fluid in the dirty liquid containing assembly 20, and pass the clean airflow to the handheld vacuum device 30, thereby improving the filtering efficiency. In addition, it can prevent the water accumulated during the floor washing process from entering the handheld vacuum device 30, thereby affecting the use of the handheld vacuum device 30. Among them, a fluid inlet 201 is provided at the lower end of the dirty liquid containing assembly 20, and the fluid inlet 201 is connected to the cleaner head assembly. A hose can be provided between the cleaner head assembly and the fluid inlet 201, and the mixed fluid can enter the cleaner head assembly through the inlet of the cleaner head assembly, and then pass through the hose to the fluid inlet 201, so as to enter the dirty liquid containing assembly 20 for filtration.

[0032] Specifically, if Figure 2, a guide pipe 22 is provided in the dirty liquid holding component 20, and the first-stage filter component 21 may include a baffle 211, a first filter element 212 and other structures, wherein the inlet of the guide pipe 22 is connected to the fluid inlet 201, and the first filter element 212 is arranged around the outlet end of the guide pipe 22, and the baffle 211 is opposite to the outlet of the guide pipe 22, and guides the fluid toward 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, flows along the guide pipe 22, and is blocked by the baffle 211 after being discharged from the outlet of the guide pipe 22. The solid waste and liquid waste in the mixture will be blocked by the baffle 211, and then fall to the first filter element 212, wherein the solid waste will be retained in the first filter element 212, and the liquid waste will be filtered by the first filter element 212 and retained in the dirty liquid holding component 20. In addition, the gas in the mixed fluid will bypass the baffle 211 and flow to the outlet of the dirty liquid containing assembly 20. A second filter element 23 can be provided at the outlet of the dirty liquid containing assembly 20. The gas in the mixed fluid will be sent out of the dirty liquid containing assembly 20 after being filtered by the second filter element 23.

[0033] In addition, if Figure 6 The handheld vacuum cleaner 30 includes a second-stage filter component 31 and an airflow drive component, wherein the airflow drive component may include a motor, the second-stage filter component 31 is configured to filter the fluid flowing through the handheld vacuum cleaner 30, and the airflow drive component is configured to drive the fluid. In the aforementioned first state, the filtering effect on the mixed fluid can be optimized by the cooperation of the first-stage filter component 21 and the second-stage filter component 31, and the filtering pressure of the second-stage filter component 31 can be reduced by filtering the mixed fluid by the first-stage filter component 21, thereby improving the filtering effect. In addition, in the second state, the second-stage filter component 31 can be configured to independently filter the mixed fluid, that is, the handheld vacuum cleaner 30 is used alone, and the fluid is filtered through the second-stage filter component 31, which can be suitable for different scenarios. Of course, in other embodiments, the liquid will be collected by the dirty liquid holding component 20, and the airflow will enter the handheld vacuum device 30 for dust and gas separation. At this time, there is no liquid entering the handheld vacuum device 30. The handheld vacuum device 30 is mainly used for filtering dry airflow and does not deal with liquid dirt. This can simplify the design difficulty of the handheld vacuum device 30, reduce costs, and avoid the handheld vacuum device 30 filtering wet garbage to cause excessive dirt, which is not conducive to cleaning, thereby improving the user experience.

[0034] In some embodiments, such as Figure 6 The handheld vacuum cleaner 30 includes a first handle 36. The handheld vacuum cleaner 30 can be used conveniently. In addition, by providing the first handle 36, the handheld vacuum cleaner 30 can be used conveniently, and the problem of not being able to find the handle when the handheld vacuum cleaner 30 is needed can be avoided.

[0035] Alternatively, if Figure 6 The handheld vacuum cleaner 30 includes an air inlet 33, a motor 34, a battery 35 and a first handle 36 which are sequentially distributed along the axial direction. The handheld vacuum cleaner 30 has a rechargeable battery 35 and a motor 34. The motor 34 of the handheld vacuum cleaner 30 is used to provide negative pressure, and the battery 35 of the handheld vacuum cleaner 30 is used to provide electrical energy. There is no need to provide an additional motor 34 and battery 35, which saves costs, optimizes the structural layout, and indirectly makes the product miniaturized. The air inlet 33, the filter, the motor 34, the battery 35, and the first handle 36 are sequentially arranged along the axis of the handheld vacuum cleaner 30. The parts layout structure is compact, and the one-line machine is more convenient to use. The handheld vacuum cleaner 30 can be used alone and is suitable for more application scenarios. In addition, a multi-cone filter 311, a motor pre-filter 312, etc. are provided between the air inlet 33 and the motor 34. In addition, the handheld vacuum cleaner 30 includes a housing, a second-stage filter assembly 31 and an airflow drive assembly are arranged in the housing, an air inlet 33 is arranged at one end of the housing, and a first handle is arranged 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.

[0036] Optionally, the handheld vacuum cleaner 30 is disposed above the dirty liquid containing assembly 20. The body 10 is provided with a docking port 101 for matching the air inlet end of the handheld vacuum cleaner 30, and the air inlet end of the handheld vacuum cleaner 30 is inserted into the docking port 101 to communicate with the dirty liquid containing assembly 20.

[0037] In some embodiments, such as 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, the upper end of the body 11 is connected to the second handle 12, the dirty liquid containing assembly 20 and the handheld vacuum device 30 are arranged on the rear side of the body 11, and the clean water containing assembly 40 is arranged on the front side of the body 11.

[0038] The utility model provides some three-in-one multifunctional vacuum cleaners with floor vacuuming, floor cleaning and handheld vacuuming, including a body 11, a second handle 12, a handheld vacuum device 30, a dirty liquid containing component 20 and a clean water containing component 40, and a cleaner head component 50. The rear of the body 11 can be designed with a convex mounting seat; the handheld vacuum device 30 is arranged above the mounting seat and can be detached or mounted on the body 11 alone; the dirty liquid containing component 20 is arranged below the mounting seat and can be detached or mounted on the body 11 alone. A through hole is provided in the mounting seat for allowing the fluid to enter the handheld vacuum device 30 through the dirty liquid containing component 20, and the handheld vacuum device 30 and the dirty liquid containing component 20 can be detachably sealed at the top and bottom of the through hole, respectively. Improving the installation stability of the vacuum device is beneficial to ensuring the sealing of the fluid joint of the vacuum device, and facilitating the user to handle the garbage in the dirty liquid containing component 20, thereby improving the user experience.

[0039] When the vacuum cleaner is in operation, a handheld vacuum cleaner 30 and a dirty liquid container assembly 20 need to be installed. The handheld vacuum cleaner 30 is used to provide suction for sucking up dirt, and the dirty liquid container assembly 20 is used to at least partially store the sucked dirt. The handheld vacuum cleaner 30 can be any wireless handheld vacuum cleaner 30 in the prior art (such as a handheld vacuum cleaner), which includes a dust cylinder assembly and a power assembly; when the handheld vacuum cleaner 30 is removed separately, it can be used in scenarios where the floor cleaning device 100 is not suitable (such as a small space for use, the surface to be cleaned is easily contaminated, etc.). The dirty liquid container assembly 20 can be removed separately, which makes it easier to handle dirt. There is no need to remove additional components when cleaning dirt, which ensures convenience during use.

[0040] The fluid in the utility model can be a clean airflow or an airflow entrained with pollutants; the pollutants are at least one of dust, solid pollutants (such as cigarette butts, paper scraps, rice grains, etc.), and dirty liquid (such as orange juice, dirty water, egg liquid, etc.).

[0041] It can be understood that in the wet and dry upright vacuum cleaner mode, the dirty liquid storage assembly 20 constitutes a first separation structure; when the airflow containing dirt passes through the dirty liquid storage assembly 20, the dirty liquid, solid dirt and dust contained therein can be intercepted and stored in the dirty liquid storage assembly 20. Since dust and gas-liquid (gaseous liquid droplets) have the characteristics of small volume and light weight, they will inevitably be guided to the dust cylinder assembly together with the airflow; in this way, the dust cylinder assembly constitutes a second separation structure. If there is dirt in the airflow entering the dust cylinder assembly, the dust cylinder assembly can separate the dust and gas, intercept and store the dirt in the dust cylinder assembly, and guide the airflow to the power assembly for discharge.

[0042] In addition, the cleaner head assembly 50 and the dirty liquid containing assembly 20 are fluidically connected through a connecting channel, and the connecting channel can be arranged in the body 11, so that the fluid inlet 201 of the dirty liquid containing assembly 20 is not limited to being arranged at the bottom. Of course, in some embodiments, a connecting channel is arranged between the bottom of the dirty liquid containing assembly 20 and the cleaner head assembly 50, and the connecting channel is used for the mixed fluid to pass from the cleaner head assembly 50 into the dirty liquid containing assembly 20.

[0043] In addition, the dirty liquid containing assembly 20 includes a sewage inlet channel, and the inlet of the sewage inlet channel is arranged at the bottom, side or upper part of the dirty liquid containing assembly 20. When using a vacuum cleaner for cleaning, the fluid enters the dirty liquid containing assembly 20 to perform the first-level separation of gas, dust and / or liquid.

[0044] Optionally, a cyclone separator is provided in the dirty liquid containing assembly 20, so that after the mixed fluid enters the dirty liquid containing assembly 20, the gas, dust and / or liquid are centrifugally separated, the dust and / or liquid are stored at the bottom of the dirty liquid containing assembly 20, and the separated gas flows out from the middle upward. The cyclone separator can be any separator capable of centrifugal separation in the prior art, and is not limited in the present invention.

[0045] Furthermore, the body 11 is rod-shaped as a whole, having a lower end and an upper end; the lower end is configured as a floor brush connection end for being pivotally connected to the cleaner head assembly 50, and the upper end is configured as a handle connection portion for detachably inserting the second handle 12.

[0046] This solution minimizes the requirement for the supporting area of ​​the fuselage 11. The fuselage 11 can be constructed as a slender rod, which reduces the overall weight of the fuselage 11. Compared with the prior art, the overall weight of the fuselage 11 can be reduced by more than 70%, and the appearance of the entire machine is more simple and elegant.

[0047] In order to improve the use stability of the upright floor cleaning device 100 , a support base is provided at the lower part of the body 10 , and the dirty liquid containing assembly 20 is supported on the body 10 through the support base.

[0048] In the present invention, 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 dirty liquid containing assembly 20. In the wet and dry dual-use mode, the handheld vacuum cleaner 30 can be fixed on the mounting seat and the body 11 by the first locking structure, and the dirty liquid containing assembly 20 can be fixed on the mounting seat, the dirty liquid containing assembly 20 support seat and the body 11 by the second locking structure. Thus, the handheld vacuum cleaner 30 and the dirty liquid containing assembly 20 can be independently detachable and independently fixed; wherein, the first locking structure and the second locking structure can adopt a locking structure, a snap-on structure, etc. well known to ordinary technicians in the field, and are not further limited in the present invention.

[0049] In the utility model, the support seat of the dirty liquid container assembly 20 can pivot relative to the fuselage 11; when the second locking structure is unlocked, the support seat of the dirty liquid container assembly 20 can automatically rotate relative to the fuselage 11, thereby driving the dirty liquid container assembly 20 to a state that is convenient to take. Specifically, the support seat of the dirty liquid container assembly 20 is constructed as a swing structure, and the dirty liquid container assembly 20 is automatically swung out relative to the fuselage 11 through the swing structure; the swing structure includes an interface member and a connector member, the interface member is arranged on one of the dirty liquid container assembly 20 and the fuselage 11, and the connector member is arranged on the other; the swing structure also includes an elastic member, when the interface member is arranged on the fuselage 11, the elastic member applies force between the interface member and the fuselage 11, and is used to bounce one end of the interface member away from the fuselage 11; when the connector member is arranged on the fuselage 11, the elastic member applies force between the connector member and the fuselage 11, and is used to bounce one end of the connector member away from the fuselage 11; further, the dirty liquid container assembly 20 can be linked to swing out.

[0050] The three-in-one wet and dry multifunctional floor cleaning device 100 in the utility model also includes a connecting piece and a brush head piece, which is used to connect with the handheld vacuum cleaner 30 when the handheld vacuum cleaner is used alone; wherein the connecting piece includes a hose, a long connecting piece, etc., and the brush head piece includes a mite removal brush, a flat brush, a hair brush, a pet brush, etc.

[0051] It is understandable that when the handheld vacuum cleaner 30 is used alone, it can be used directly, or it can be connected to accessories such as a mite removal brush, a flat brush, a hair brush, a pet brush, etc. It is also possible to transfer hoses, long pipes and other accessories between the handheld vacuum cleaner 30 and the accessories, thereby achieving whole-house cleaning in a variety of scenarios.

[0052] In the present invention, the second handle 12 can be used as a long connecting pipe in combination with the handheld vacuum cleaner 30 , which can reduce the space occupied by accessories and reduce the cost of accessories.
