Description

Technical Field

[0001] The present invention relates to the field of cleaning, and particularly to a vacuum cleaning system and method with air duct switching. Background Art

[0002] Vacuum cleaners are becoming more and more popular in domestic households. To facilitate the storage and charging of vacuum cleaners, some manufacturers configure a base station to empty the dust of the vacuum cleaner. However, this base station usually requires a base station motor to achieve this, which not only increases the cost of the base station but also results in a relatively large space for the base station, making it not conducive to miniaturization. Such technologies can be referred to in Chinese invention patent CN112438650A. Therefore, it is necessary to make improvements. Summary of the Invention

[0003] The purpose of the present invention is to provide a vacuum cleaning system and method with air duct switching that can effectively solve the above technical problems. By using the same suction motor to achieve the cyclone cleaning mode and the dust discharging mode of the storage main body, the cost of the base station is reduced and the miniaturization of the base station is facilitated.

[0004] To achieve the purpose of the present invention, the following first technical solution is adopted: A vacuum cleaning system with air duct switching, which includes a vacuum cleaner and a storage main body for storing the vacuum cleaner and capable of being placed on a horizontal plane. The vacuum cleaner includes a suction housing, a suction dust cup cooperating with the suction housing, a suction motor located in the suction housing, and an air duct switching device cooperating with the suction motor and switching air ducts. The storage main body includes a docking part selectively communicating with the suction dust cup. The air duct switching device includes an air duct base at least partially accommodating one end of the suction motor, an air duct cover at least partially accommodating the other end of the suction motor and connected to the air duct base, and an air duct switching part triggered by the docking part. The air duct cover has at least two air flow channels, and the air duct switching part is selectively communicated with one of the air flow channels.

[0005] On the basis of the above technical solution, the following subsidiary technical solutions are further included:

[0006] The air duct cover includes a first channel opening communicating with the first air flow channel and a second channel opening communicating with the second air flow channel. The first channel opening and the second channel opening have a height difference in the vertical plane direction and are spaced apart in the circumferential direction to achieve air duct switching when the vacuum cleaner is placed in the storage main body.

[0007] The first air flow channel is a bypass channel between the outer peripheral side of the air duct cover and the central air inlet side of the suction motor, and the second air flow channel is an inner channel between the outer peripheral side of the air duct cover and the inner side of the air duct cover cavity, to ensure the central air inlet of the suction motor and to make the motor head of the suction motor located above the motor tail.

[0008] The air duct base includes a base transition cavity communicating with one end of the dust suction cup, a base accommodation cavity for accommodating the dust suction motor, a base passage communicating with the base transition cavity, and a base through-hole located between the base transition cavity and the base passage, so as to isolate the base transition cavity and the base accommodation cavity from each other, and conduct air flow through the base passage.

[0009] The air duct switching member includes a main air duct that can reciprocate in the base passage, a branch air duct communicating with the main air duct, a first branch air duct opening located on one side of the branch air duct, and a second branch air duct opening located on the other side of the branch air duct. The first branch air duct opening is selectively communicated with the first passage opening, and the second branch air duct opening is selectively communicated with the second passage opening to achieve air duct switching.

[0010] It further includes a cover portion that accommodates the dust suction motor and the air duct switching device and is open at one end, and a partition member that at least partially shields the open end of the cover portion. The partition member includes a partition hole communicating with the base transition cavity, and the cover portion includes a plurality of cover portion holes located on one side and capable of communicating with the first passage opening. A distance is always maintained between the bottom of the main air duct and the partition member to ensure the entry of air flow. In different modes, the air flow passes through the partition hole, simplifying the air duct structure.

[0011] The dust suction motor includes a motor head and a motor tail. The motor tail is located between the motor head and the partition member. The central extension direction of the partition hole passes through the motor head. The base transition cavity and the base accommodation cavity are isolated from each other, and the base accommodation cavity is located above the base transition cavity in the direction perpendicular to the horizontal plane, ensuring the air intake direction of the motor head and simplifying the internal air duct structure.

[0012] The second technical solution of the present invention: A method, which includes:

[0013] Step S100: First, provide a vacuum cleaning system, which includes a vacuum cleaner and a storage main body for storing the vacuum cleaner and capable of being placed on a horizontal plane. The vacuum cleaner includes a dust suction housing, a dust suction cup cooperating with the dust suction housing, a filter assembly located in the dust suction cup, a dust suction motor located in the dust suction housing, and an air duct switching device cooperating with the dust suction motor and switching the air duct. The storage main body includes a docking portion selectively communicating with the dust suction cup. The vacuum cleaner has a cleaning mode and a storage main body dust discharging mode. If the cyclone cleaning mode is selected, step S200 is entered, and if the storage main body dust discharging mode is selected, step S300 is entered.

[0014] Step S200: When the vacuum cleaner is in the cyclone cleaning mode, the vacuum motor is started first, and the airflow enters from the air inlet end of the dust cup and generates a cyclone in the dust cup to separate dust and gas, and then enters the air duct switching device through the outer surface of the filter assembly, thereby entering the vacuum motor, and then flows out through the air duct switching device to be discharged to the outside until the end;

[0015] Step S300: When the vacuum cleaner is in the storage body dust discharge mode, the docking part triggers the air duct switching device to switch the air duct, and then starts the vacuum motor. The airflow enters an air duct of the air duct switching device from the outside, and then flows out from the vacuum motor, and then passes through another air duct of the air duct switching device, and continues to pass through the inner surface of the filter assembly to empty the garbage in the dust cup to the docking part until the end.

[0016] On the basis of the second technical solution, the present invention provides the following subsidiary technical solutions:

[0017] In step S200, the vacuum cleaner has a cyclone cleaning air duct, wherein the cyclone cleaning air duct at least includes a cyclone separation section located in the dust cup, a filtering cleaning section located in the filter assembly and moving from the outer surface to the inner surface, a motor cleaning front air flow section located in the air duct switching device, and a motor cleaning rear air outlet section located in the dust housing, so as to perform cyclone cleaning.

[0018] In step S300, the vacuum cleaner has a dust removal air duct for the storage body, wherein the dust removal air duct for the storage body at least includes an external air induction section located in the dust collection shell, a motor front air induction section located in the air duct switching device, a motor rear air guide section located in the dust collection shell, an air blowing filter section located in the filter assembly and moving from the inner surface to the outer surface, and an air blowing dust removal section located in the dust cup, so as to carry out dust removal of the storage body. The movement direction of the filter cleaning section in the cyclone cleaning air duct is opposite to the movement direction of the air blowing filter section in the dust removal air duct for the storage body, so as to reduce dust accumulation in the filter assembly and improve the filtering performance.

[0019] The third technical solution of the present invention: a duct switching device for a vacuum cleaner, wherein the vacuum cleaner includes a dust cup and a dust motor, wherein the duct switching device includes a duct base that at least partially accommodates one end of the dust motor, a duct cover that at least partially accommodates the other end of the dust motor and is connected to the duct base, and an duct switching component that is triggered and moves to allow airflow to flow; wherein the duct cover has at least two airflow channels connected to the dust motor, and the duct switching component is selectively connected to one of the airflow channels.

[0020] Compared with the prior art, the present invention has the following beneficial effects: a cyclone cleaning mode and a storage body dust removal mode are realized by using the same dust suction motor, which reduces the cost of the base station and facilitates the miniaturization of the base station.

[0040] As Figures 1 to 11 shown, the present invention provides a first embodiment of a vacuum cleaning system with air duct switching, which includes a vacuum cleaner cooperating with a storage main body. The storage main body may include a base station, a storage rack, a trash can, etc. The vacuum cleaner includes a vacuum housing, a vacuum dust cup 1200 cooperating with the vacuum housing, a filter assembly located in the vacuum dust cup 1200, a vacuum motor 1400 located in the vacuum housing, a connecting pipe 1500 with one end connected to the vacuum housing, a vacuum floor brush 1700 connected to the other end of the connecting pipe 1500, a cover part 1600 that houses the vacuum motor 1400 and an air duct switching device and has one end open, a partition member 1620 that at least partially shields the open end of the cover part 1600, and an air duct switching device that cooperates with the vacuum motor 1400 to switch air ducts.

The power supply housing 1060 is for a user to hold. The central extension direction of the air inlet pipe 1100 passes through the power supply housing 1060.

[0042] The dust collection cup 1200 is cylindrical and hollow inside, with a bottom that can be selectively opened or closed by an end cap, and the end cap rotates around an axis to empty the dust inside the dust collection cup 1200.

[0043] The filter assembly includes a mesh cover 1300 having a plurality of mesh holes and a secondary filter element 1340 at least partially surrounded by the mesh cover 1300. When the vacuum cleaner is in the cleaning mode, the secondary filter element 1340 is located downstream of the air flow of the mesh cover 1300.

[0044] The dust collection motor 1400 includes a motor head and a motor tail, and the motor tail is located between the motor head and a partition member 1620.

[0045] The interior of the cover portion 1600 is hollow and includes a cover portion cavity 1604 located therein and open at one end, a plurality of cover portion holes 1640 located outside the cover portion cavity 1604, and a cover portion slide rail 1644 located outside the cover portion cavity 1604 and circumferentially spaced from the cover portion holes 1640. The partition member 1620 is used to close the open end of the cover portion cavity 1604 and is generally plate-shaped, including a partition hole 1622 adjacent to the secondary filter element 1340 and centrally disposed.

[0046] The air duct switching device includes an air duct base 1610 that at least partially houses one end of the dust suction motor 1400, an air duct cover 1630 that at least partially houses the other end of the dust suction motor 1400 and is connected to the air duct base 1610, an air duct switching member 1650 that is touched by the docking portion 2200, and an elastic member 1609 that provides a resilience force for the air duct switching member 1650. The air duct cover 1630 has at least two air flow channels, and the air duct switching member 1650 is selectively communicated with one of the air flow channels. The air duct cover 1630 includes an air duct cover cavity 1632 located therein and at least partially housing the motor head, a first channel port 1634 located on one side of the air duct cover cavity 1632 and communicated with the first air flow channel, a bypass channel 1636 located between the first channel port 1634 and the air inlet side of the motor head, and a second channel port 1638 communicated with the second air flow channel and communicated with the air duct cover cavity 1632. The first channel port 1634 and the second channel port 1638 have a height difference in the direction perpendicular to the horizontal plane and are spaced apart in the circumferential direction. The first air flow channel is the bypass channel 1636 located between the outer peripheral side of the air duct cover 1630 and the central air inlet side of the dust suction motor 1400, and the second air flow channel is the inner channel located between the outer peripheral side of the air duct cover 1630 and the inner side of the air duct cover cavity 1632. The air duct base 1610 includes a base transition cavity 1611 communicated with one end of the dust suction cup 1200, a base housing cavity 1612 housing the dust suction motor 1400, a base channel 1614 communicated with the base transition cavity 1611, and a base through hole 1616 located between the base transition cavity 1611 and the base channel 1614. The base through hole 1616 is located on one side of the base transition cavity 1611, is perpendicular to the air inlet direction of the partition hole 1622, and does not interfere with the moving main air duct 1652 in different modes and does not affect the ventilation area of the base through hole 1616. The air duct switching member 1650 includes a main air duct 1652 that can reciprocate in the base channel 1614, a branch air duct 1653 communicated with the main air duct 1652, a first branch air duct port 1654 located on one side of the branch air duct 1653, a second branch air duct port 1656 located on the other side of the branch air duct 1653, a sliding piece 1658 connected to the main air duct 1652 or the branch air duct 1653 and reciprocatingly moving in the cover rail 1644, and a mounting post 1659 located at one end of the branch air duct 1653 and mounting the elastic member 1609. The first branch air duct port 1654 is selectively communicated with the first channel port 1634, and the second branch air duct port 1656 is selectively communicated with the second channel port 1638. The base transition cavity 1611 and the base housing cavity 1612 are isolated from each other, and the base housing cavity 1612 is located above the base transition cavity 1611 in the direction perpendicular to the horizontal plane. The central extension direction of the partition hole 1622 sequentially passes through the base transition cavity 1611, the base housing cavity 1612, the motor tail, and the motor head.The sliding vane 1658 is exposed on the outside and is located outside the base channel 1614, while the main air duct 1652 is located inside the base channel 1614, and the branch air duct 1653 is located on the top side of the base channel 1614.

[0047] In this embodiment, since the vacuum cleaner selects the cyclone cleaning mode, the cyclone cleaning air duct starts from sucking the dirty air flow on the horizontal plane by the dust suction floor brush 1700, and successively passes through the connecting pipe 1500 and the air inlet pipe 1100, and then enters the dust suction dust cup 1200 for cyclone separation. The separated air flow then successively passes through the outer surface of the mesh cover 1300 and the secondary filter element 1340, that is, moves from the outer surface to the inner surface to achieve double filtration, and then enters the base transition cavity 1611 through the partition hole 1622, and continues to enter the main air duct 1652 along the base through hole 1616 located on the side. At this time, since one end of the first branch air duct opening 1654 is communicated with one end of the first channel opening 1634, and the other end of the first channel opening 1634 is communicated with the bypass channel 1636, the central air intake of the dust suction motor 1400 is completed, and then it flows out from one side of the air duct cover cavity 1632, that is, the second channel opening 1638, and then passes through the first motor rear air outlet channel 1680, and finally is discharged to the outside through the cover hole 1640 located at the end of the first motor rear air outlet channel 1680.

[0048] As Figures 12 - 16 shown, the second embodiment of the present invention provides a vacuum cleaning system with air duct switching, which includes a vacuum cleaner 1000 and a storage main body 2000 for storing the vacuum cleaner 1000 and capable of being placed on a horizontal plane. The vacuum cleaner 1000 is the vacuum cleaner of the first embodiment, and this embodiment is the embodiment in the dust discharging mode of the storage main body, and the vacuum cleaner 1000 selects the dust discharging mode of the storage main body. The storage main body 2000 is preferably a base station in this embodiment, and can also be a storage rack, a trash can, etc. The storage main body 2000 includes a docking part 2200 located above, and the docking part 2200 includes a top rod 2240 located at the upper end and abutted against the sliding vane 1658. A dust bag 2400 can be arranged inside the docking part 2200 for collecting the dust inside the dust suction dust cup 1200. The docking part 2200 is also provided with a trigger structure for opening the end cover of the dust suction dust cup 1200, and the end cover rotates to open so that the dust on the end cover falls into the dust bag under the action of gravity. When the vacuum cleaner is placed in the storage main body 2000, the top rod 2240 pushes the sliding vane 1658 upward, and the sliding vane 1658 moves upward along the cover rail 1644, thereby compressing the elastic member 1609. At this time, the main air duct 1652 moves upward along the base channel 1614. There is a DC power supply 1080 in the power supply housing 1060 to supply power to the dust suction motor 1400. The dust suction dust cup 1200 includes a dust cup cavity 1220 capable of generating a cyclone and an end cover 1240 for opening or closing the bottom of the dust cup cavity 1220.

[0049] In this embodiment, since the dust collector 1000 selects the dust discharging mode of the storage main body, starting from the intake of external air through the dust discharging air duct of the storage main body from the cover hole 1640, at this time, one end of the first channel opening 1634 is in communication with the cover hole 1640, and the external air flow then enters the bypass channel 1636, thereby completing the central air intake of the dust collection motor 1400, and then flowing out from one side of the air duct cover cavity 1632, that is, the second channel opening 1638. At this time, since the second channel opening 1638 is in communication with the second branch air duct opening 1656, and then passes through the air outlet channel 1690 after the second motor, the external air flow thus enters the main air duct 1652 downward, and then enters the base transition cavity 1611 through the base through hole 1616 located on the side, and then passes through the partition hole 1622 downward and sequentially passes through the inner surfaces of the mesh cover 1300 and the secondary filter element 1340, that is, moves from the inner surface to the outer surface, so as to perform a blowing action on the dust remaining on the filter assembly, prevent the accumulation of dust, and improve the filtering performance; the air flow passing through the filter assembly further moves downward. Since the end cover is rotated and opened at this time, combined with the action of gravity when the air flow moves downward, the dust in the dust collection cup 1200 enters the dust bag of the docking part 2200, so as to complete the dust discharging of the storage main body.

[0050] Based on the above embodiments, the present invention further provides a third embodiment of a method, which includes:

[0051] Step S100: First, provide a vacuum cleaning system, which includes a dust collector, and a storage main body 2000 for storing the dust collector and capable of being placed on a horizontal plane. The dust collector includes a dust collection housing, a dust collection cup 1200 cooperating with the dust collection housing, a filter assembly located in the dust collection cup 1200, a dust collection motor 1400 located in the dust collection housing, and an air duct switching device cooperating with the dust collection motor 1400 to switch the air duct; the storage main body 2000 includes a docking part 2200 selectively communicating with the dust collection cup 1200; the dust collector has a cyclone cleaning mode and a dust discharging mode of the storage main body. Selecting the cleaning mode enters step S200, and selecting the dust discharging mode of the storage main body enters step S300;

[0052] Step S200: When the vacuum cleaner is in the cyclone cleaning mode, first start the dust suction motor 1400. Then, the air flow enters from the air inlet end of the dust suction dust cup 1200 and generates a cyclone inside the dust suction dust cup 1200 to separate dust from the air. Then, it enters the air duct switching device through the outer surface of the filter assembly, thus entering the dust suction motor 1400, and then flows out through the air duct switching device and is discharged to the outside to end. In the step S200, the vacuum cleaner has a cyclone cleaning air duct, and the cyclone cleaning air duct at least includes a cyclone separation section located inside the dust suction dust cup 1200, a filter cleaning section located inside the filter assembly and moving from the outer surface to the inner surface, a motor cleaning forward air inlet section located inside the air duct switching device, and a motor cleaning rear air outlet section located inside the dust suction housing.

[0053] Step S300: When the vacuum cleaner is in the storage main body ash discharging mode, the docking part 2200 touches the air duct switching device to switch the air duct. Then, start the dust suction motor 1400. The air flow enters from the outside into one air duct of the air duct switching device, then flows out from the dust suction motor 1400, then passes through the other air duct of the air duct switching device, and continues to pass through the inner surface of the filter assembly to empty the garbage in the dust suction dust cup 1200 to the docking part 2200 to end. In the step S300, the vacuum cleaner has a storage main body ash discharging air duct, and the storage main body ash discharging air duct at least includes an external air guiding section located inside the dust suction housing, a motor front air guiding section located inside the air duct switching device, a motor rear air guiding section located inside the dust suction housing, a blowing and filtering section located inside the filter assembly and moving from the inner surface to the outer surface, and a blowing and ash discharging section located inside the dust suction dust cup 1200.

[0054] Based on the above embodiments, the present invention further provides a fourth embodiment of an air duct switching device for a vacuum cleaner. The vacuum cleaner includes a dust suction dust cup 1200 and a dust suction motor 1400. The air duct switching device includes an air duct base 1610 that at least partially houses one end of the dust suction motor 1400, an air duct cover 1630 that at least partially houses the other end of the dust suction motor 1400 and is connected to the air duct base 1610, and an air duct switching member 1650 that is triggered to move and allows air flow. The air duct cover 1630 has at least two air flow channels communicating with the dust suction motor 1400, and the air duct switching member 1650 is selectively communicated with one of the air flow channels. In this embodiment, the user can directly trigger the air duct switching member 1650 to move by pressing a button. The bottom of the dust suction dust cup 1200 is opened to discharge ash, and the internal dust can be poured into a trash can or a garbage bag.

[0055] Advantages of the present invention: The cyclone cleaning mode and the storage main body ash discharging mode are realized by the same dust suction motor, reducing the cost of the storage main body and facilitating the miniaturization of the storage main body.
