[0002] At present, the vacuum cleaner system usually includes a vacuum cleaner device (such as a vacuum cleaner) and a dust collection station. The vacuum cleaner can be used for dust extraction through the dust collection station, without the need for the user to manually empty the dust. The dust collection station is provided with a docking port, a dust bag for collecting dust, and a dust collection station motor that provides negative pressure for dust extraction. When the vacuum cleaner is docked with the docking port of the dust collection station, negative pressure is generated by the action of the dust collection station motor, which can extract the dust in the dust cup of the vacuum cleaner. In this way, the user does not need to empty the dust after each cleaning, and the user can empty the dust once a month or even longer. However, the dust in the dust bag in the vacuum cleaner device may adhere to the inner wall, resulting in residue and reducing the dust removal effect. Utility Model Content

On the one hand, the positive pressure can assist The negative pressure in the dust collecting chamber helps to transfer the dirt in the dust storage chamber to the dust collecting chamber more quickly and efficiently. On the other hand, since the positive pressure is opposite to the negative pressure formed when the vacuum cleaner device performs the vacuuming operation normally, that is, it is basically opposite to the direction of the vacuuming air path of the vacuum cleaner device, it helps to blow off the dirt attached to the dust storage chamber during the vacuuming operation, such as the inner cavity wall and the outer wall of the built-in component, which helps to clean the built-in components and discharge the dirt in the dust storage chamber more thoroughly, thereby ultimately helping to optimize the dust removal effect of the vacuum cleaner device.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] The present invention provides a vacuum cleaner system, which includes a dust collection station and a vacuum cleaner device 200. The specific form of the vacuum cleaner device 200 is not limited, and in actual application, the use orientation of the vacuum cleaner device 200 may be different. However, for ease of understanding, in the following embodiments, Figures 1 to 13 The handheld vacuum cleaner device 200 is taken as an example for description. At this time, the vacuum cleaner device 200 has a substantially vertical up-down direction and a horizontal direction.

[0055] In view of this, the vacuum cleaner device 200 can generally be divided into multiple components according to its functions, such as but not limited to the air inlet part 250 and the dust cup, and according to actual needs, it can also include the air outlet part 260.

[0056] The air inlet 250 is the structural component that allows external air to enter the dust cup. The air inlet 250 generally forms an air inlet duct, and the upstream air duct opening of the air inlet duct generally directly constitutes the air inlet of the entire machine. Depending on actual needs, the air inlet 250 can also be equipped with various accessory brush heads for cleaning in different scenarios, such as pet brushes, crevice brushes, and mite removal brushes.

[0057] A dust storage chamber 221 is formed inside the dust cup. Specifically, the dust cup includes a cup body 220 and a cup cover 230. The cup body 220 is formed with a dust storage chamber 221, and the cup body 220 is provided with an inlet 222, an outlet 223 and a dust exhaust port 225 connected to the dust storage chamber 221; the cup cover 230 is movably mounted on the cup body 220, and can open and close the dust exhaust port 225. The inlet 222 of the dust storage chamber 221 is connected to the downstream air duct port of the air inlet channel. The cup body 220 can be configured as a columnar structure extending in the up and down directions. In this case, the air inlet portion 250 can be roughly arranged on one side of the dust cup in the horizontal direction, and the air inlet portion 250 and the air inlet duct formed therein can be roughly arranged to extend in the horizontal direction.

[0058] An air outlet duct is generally formed inside the air outlet portion 260, and the upstream air outlet of the air outlet duct is connected to the outlet 223 of the dust storage chamber 221. The downstream air outlet of the air outlet portion 260 can generally directly constitute the air outlet of the entire machine, so that after the dust cup intercepts the dirt in the gas carrying dirt in the dust storage chamber 221, the air outlet portion 260 can discharge the relatively clean gas to the outside through the air outlet.

[0059] like Figures 1 to 3 As shown, in order to make the structure of the whole machine compact, the dust cup and the air outlet 260 can be arranged to extend in a columnar shape along the vertical direction, and the air outlet 260 is arranged above the dust cup. The air inlet 250 is arranged on one side of the dust cup along the horizontal direction.

[0060] In view of the above, the vacuum cleaner device 200 can at least be used for vacuuming. In order to achieve the purpose of gas entering the air inlet duct from the air inlet, passing through the dust cup and the air outlet 260, and finally being discharged outward from the air outlet, in a specific application, the vacuum cleaner device 200 also includes an air expelling device 210. The air expelling device 210 refers to any device that can achieve the purpose of driving the directional flow of gas, which can be composed of a single component (such as a fan) alone, or composed of at least two single components (such as a fan and an air guide structure). The air expelling device 210 can include a fan, which can be but not limited to an axial flow fan, a cross-flow fan, a centrifugal fan, etc. The air expelling device 210 generally has a suction side 211 and an exhaust side 212 under normal operating conditions. When started, the suction side 211 of the air expelling device 210 forms a negative pressure, which can suck the external air flow into the interior of the air expelling device 210; the exhaust side 212 forms a positive pressure, which can discharge the air flow inside the air expelling device 210 outward.

[0061] In actual application, the exhaust side 212 of the air purging device 210 can be connected to the air inlet to blow gas into the air inlet duct, so as to achieve the purpose of driving the gas from the air inlet into the air inlet duct, passing through the dust storage chamber 221 and the air outlet duct, and finally being discharged outward from the air outlet. However, in order to reduce the adverse effect of the setting of the air purging device 210 on the air flow of the air inlet part 250, in the following example, Figures 1 to 13 In the illustrated embodiments, the structure in which the suction side 211 of the purge device 210 is connected to the downstream air duct opening of the air outlet duct, and the exhaust side 212 of the purge device 210 constitutes the air outlet of the entire machine is used as an example for illustration.

[0062] In addition, in order to achieve the purpose of trapping the dirt carried in the external air connected to the air inlet 250 in the dust storage chamber 221, in a specific application, the vacuum cleaner device 200 may also include at least one filter 240, which is at least arranged in the dust storage chamber 221 and located between the inlet 222 and the outlet 223. Of course, the filter 240 can also be arranged in the air outlet duct. There is no limitation on the number and specific type of the filter 240, for example Figures 2 to 3 As shown, the filter element 240 can be, but is not limited to, one or more of a porous filter, a multi-cone filter, and a pre-filter. For example, the porous filter and the multi-cone filter are both arranged in the upstream section of the dust storage chamber 221. The pre-filter is roughly cylindrical and arranged in the downstream section of the dust storage chamber 221, for example, specifically arranged at the connection point between the dust storage chamber 221 and the air outlet duct, or directly arranged at the air outlet duct. Generally, the structure composed of the dust cup and at least one filter element 240 is also commonly referred to as a dust cup assembly.

[0063] In addition, in order to realize the orderly operation of each component in the vacuum cleaner system, the vacuum cleaner system may also include a power supply device and a control device. Among them, the power supply device may include but is not limited to a one-time charge and discharge power supply device, such as a disposable battery; or the power supply device may also include a repeatedly charge and discharge power supply device, such as a product such as a battery that can be electrically connected to the mains. The power supply device can be arranged in the housing of the vacuum cleaner device 200, for example, on the side of the air purging device 210 facing away from the air outlet 260 / dust cup. The control device can at least be electrically connected to the power supply device and the air purging device 210, so as to be able to control the charging and discharging of the power supply device, and control the air purging device 210 to start and stop running, and adjust the preset operating power according to actual needs, such as according to a preset program or in response to a user's trigger instruction. The control device can be built into the vacuum cleaner device 200, or it can be externally placed at, for example, a dust collection station or other location according to actual needs, and realize communication with the air purging device 210 on the vacuum cleaner device 200, for example, by means of a wireless connection. As Figures 2 to 3 As shown, the power supply device can be arranged on a side of the air purging device 210 away from the air inlet portion 250 and opposite to the air inlet portion 250 .

[0064] In addition, the vacuum cleaner device 200 and / or the dust collection station may also be provided with a display module and / or an input device. The display module includes a display panel, which may display digitally or graphically as needed. The input device may be, but is not limited to, physical or virtual buttons, a voice recognition module, a gesture recognition module, etc., allowing the user to manually enter relevant trigger commands.

[0065] Of course, depending on actual needs, the vacuum cleaner device 200 and / or the dust collection station may also be equipped with one or more sensor devices. The sensor devices are electrically connected to the control device so that the control device can intelligently control the operation of the corresponding functional components based on the sensing data of the sensor devices. For example, the sensor device can be located at the interface between the vacuum cleaner device 200 and the dust collection station, and is triggered when the vacuum cleaner device 200 and the dust collection station are docked, generating a sensor signal.

[0066] In view of any one or more of the above embodiments of the vacuum cleaner device 200, further, the dust collection station is generally a product used in conjunction with the vacuum cleaner device 200. The vacuum cleaner device 200 has a first operating state in which it operates independently from the dust collection station, and a second operating state in which it is docked with the dust collection station. When in the second operating state, the dust collection station can perform various preset operations on the vacuum cleaner device 200 under the drive of a preset program or in response to a user trigger command. The preset operations may include, but are not limited to, charging, cleaning, vacuuming, and other operations.

[0067] In view of the above, please combine Figures 1 to 13 In the vacuum cleaner system provided by the present invention, the vacuum cleaner system includes a dust collecting station and a vacuum cleaner device 200. The dust collecting station is provided with a dust collecting chamber, the vacuum cleaner device 200 is provided with a dust storage chamber 221, and the vacuum cleaner device 200 includes an air expelling device 210. After the vacuum cleaner device 200 is docked with the dust collecting station, the vacuum cleaner system has a dust extraction mode for connecting the dust collecting chamber and the dust storage chamber 221. In the dust extraction mode, the air expelling device 210 generates negative pressure in the dust collecting chamber and generates positive pressure in the dust storage chamber 221 to transfer the dirt in the dust storage chamber 221 to the dust collecting chamber.

[0068] In the technical solution provided by the present invention, after the dust collector device 200 is docked with the dust collecting station, the dust collecting station can reasonably use the air expelling device 210 on the dust collector device 200 to generate negative pressure in the dust collecting chamber, thereby facilitating the dust collecting station to use the negative pressure to transfer the dirt in the dust storage chamber 221 to the dust collecting chamber. The dust collecting station does not need to be additionally provided with structures such as a fan, so that the overall structure of the dust collecting station can be simpler and lighter, and the overall maintenance cost of the dust collecting station is lower; and at the same time, the air expelling device 210 will also generate positive pressure in the dust storage chamber 221. On the one hand, the positive pressure can assist The negative pressure of the dust collecting chamber helps to transfer the dirt in the dust storage chamber 221 to the dust collecting chamber more quickly and efficiently; on the other hand, since the positive pressure is opposite to the negative pressure formed when the vacuum cleaner device 200 performs the normal vacuuming operation, that is, it is basically opposite to the direction of the vacuuming air path of the vacuum cleaner device 200, it helps to blow off the dirt attached to the dust storage chamber 221 during the vacuuming operation, such as the inner cavity wall and the outer wall of the built-in component, which helps to clean the built-in components and more thoroughly discharge the dirt in the dust storage chamber 221, thereby ultimately helping to optimize the dust discharge effect of the vacuum cleaner device 200.

[0069] Of course, the manner in which the purge device 210 generates negative pressure in the dust collecting chamber and positive pressure in the dust storage chamber 221 is not limited. For example, when the purge device 210 is a fan and has a suction side 211 and an exhaust side 212, in the dust extraction mode, the suction side 211 is connected to the dust collecting chamber to provide negative pressure to the dust collecting chamber, and the exhaust side 212 is connected to the dust storage chamber 221 to provide positive pressure to the dust storage chamber 221. In this way, the purge device 210 on the vacuum cleaner device 200 can be fully utilized without the need to provide other additional purge devices.

[0070] When the dust cup includes a cup body 220 and a cup cover 230 as described above, and the vacuum cleaner device 200 further includes at least one filter element 240, the vacuum cleaner device 200 has a dust collection mode. In the dust collection mode, the air inlet 250 is connected to the inlet 222, and the suction side 211 is connected to the outlet 223, so that external dirt is sucked into the dust storage chamber 221 through the air inlet 250. In the dust collection mode, the cup cover 230 first covers the dust discharge port 225. The air purging device 210 provides negative pressure in the dust storage chamber 221. Under the action of this negative pressure, external air carrying dirt enters the dust storage chamber 221 through the air inlet duct and the inlet 222. Under the action of the at least one filter element 240, the dirt is intercepted and stored in the dust storage chamber 221. The remaining relatively clean air flow circulates through the outlet 223, the suction side 211, and the exhaust side 212 in sequence. At this time, the exhaust side 212 of the air purging device 210 can be configured to communicate with the above-mentioned air outlet duct, so that the air flow eventually passes through the air purging device 210 and is discharged outward through the air outlet of the entire machine.

[0071] In the dust extraction mode, the cup cover 230 is movable to open the dust discharge port 225, and the dust collecting chamber is connected to the dust storage chamber 221 through the dust discharge port 225. There is no need to open other openings in other parts of the cup body 220, so that the dirt stored in the dust storage chamber 221 can directly enter the dust collecting chamber through the dust discharge port 225.

[0072] Furthermore, in the dust extraction mode, the exhaust side 212 is connected to the outlet 223, so that clean air can be blown back into the dust storage chamber 221 through the outlet 223. In particular, when a filter 240 is provided in the dust storage chamber 221, the reverse blown air can directly blow off dirt attached to the filter 240, or cause the filter 240 to vibrate slightly, thereby shaking off dirt attached to the filter 240, thereby helping to clean the filter 240.

[0073] In view of the above, it can be seen that in the dust collection mode, the suction side 211 of the air purging device 210 is connected to the outlet 223 of the dust storage chamber 221, and the exhaust side 212 is connected to the air outlet of the entire machine; while in the dust extraction mode, the suction side 211 of the same air purging device 210 is connected to the dust collection chamber, and the exhaust side 212 is connected to the outlet 223 of the dust storage chamber 221. There are many ways to achieve the above two state switching:

[0074] In one embodiment, the position of the air purging device 210 is movable and adjustable, so that during its movement, the suction side 211 or the exhaust side 212 can be adjusted to be connected to the outlet 223, and the suction side 211 can be adjusted to be connected to the dust collecting chamber. It is understood that the positions of the dust storage chamber 221 and the dust collecting chamber are generally fixed, and by driving the air purging device 210 to perform translational movement between the dust storage chamber 221 and the dust collecting chamber, the suction side 211 can be switched between being connected to the dust storage chamber 221 and being connected to the dust collecting chamber; by driving the air purging device 210 to perform, for example, rotational movement, adjusting the suction side 211 and the exhaust side 212 to face the outlet 223 of the dust storage chamber 221 respectively, the suction side 211 can be switched between being connected to the dust storage chamber 221, or the exhaust side 212 can be switched between being connected to the dust storage chamber 221 and being connected to the dust collecting chamber.

[0075] In another embodiment, the position of the air purging device 210 is relatively fixed; the vacuum cleaner system also includes an air duct structure, and the air duct structure has a first air duct, a second air duct and a third air duct. Among them, the first air duct connects the suction side 211 and the outlet 223; the second air duct connects the exhaust side 212 and the outlet 223; the third air duct connects the suction side 211 and the dust collecting chamber; the first air duct, the second air duct and / or the third air duct can be selectively turned on and off. In actual application, the air duct structure can be two different structures that are independent of the above-mentioned air outlet 260, or the air duct structure is entirely or partially composed of the above-mentioned air outlet 260. The arrangement of the first air duct, the second air duct and the third air duct makes it possible to meet the circulation requirements respectively by reasonably designing the extension direction, flow cross-sectional area and other structural parameters of the first air duct, the second air duct and the third air duct regardless of the positional relationship among the air purging device 210, the dust collecting chamber and the dust storage chamber 221. The first air duct, the second air duct and / or the third air duct can be selectively opened and closed, so that the conduction relationship among the air purging device 210, the dust collecting chamber and the dust storage chamber 221 can be flexibly switched according to actual needs.

[0076] Among them, when the dust storage chamber 221 is provided with only one outlet 223, the first air duct and the second air duct can be connected to the same outlet 223. At this time, the first air duct and the second air duct can be set to be shared by a local air duct section. When the dust storage chamber 221 is provided with at least two outlets 223, the first air duct and the second air duct can be separately connected to different outlets 223. For example, when the dust storage chamber 221 is provided with two outlets 223, which are the first outlet and the second outlet respectively, the first air duct is connected to the suction side 211 and the first outlet; the second air duct is connected to the exhaust side 212 and the second outlet. In this way, the structural design of the first air duct and the structural design of the second air duct can be independent of each other and do not affect each other.

[0077] As described above, when the dust storage chamber 221 is provided with at least two outlets 223, since the first outlet is used for conduction during normal dust collection operation of the vacuum cleaner device 200, multiple filters 240 may be provided in sequence between the inlet 222 and the first outlet. The second outlet can be provided on the side of at least one filter element 240 facing away from the inlet 222, as required. In this way, the airflow entering the dust storage chamber 221 from the exhaust side 212 through the second outlet can be cleaned by the required filter element 240 as required.

[0078] Of course, the ventilation cross-sectional areas of the first outlet and the second outlet can be set to be the same, or they can be set to be different according to actual needs. For example, in one embodiment, the ventilation cross-sectional area of ​​the second outlet is not greater than the ventilation cross-sectional area of ​​the first outlet. In this way, it is ensured that in the dust collection mode, the air purging device 210 forms a suction airflow of sufficient strength to suck out external dirt; and when in the dust extraction mode, the air purging device 210 forms a suction airflow of sufficient strength to suck out dirt in the dust storage chamber 221, but the strength of the blowing airflow can be appropriately reduced to avoid airflow turbulence in the dust storage chamber 221 or to achieve the best dust extraction effect.

[0079] In dust extraction mode, the exhaust side can be fully routed to the second outlet. That is, the exhaust side 212 is completely connected to the second outlet. Alternatively, the exhaust side can be partially routed to the second outlet, with the remaining gas being discharged, for example, through the air outlet of the entire unit. That is, a portion of the exhaust side 212 is connected to the second outlet, while the remaining portion is connected to the air outlet.

[0080] In view of the above, it can be seen that the first air duct, the second air duct, and / or the third air duct can be selectively turned on and off. For example, the vacuum cleaner system further includes a switching device; in the vacuuming mode, the switching device turns on the first air duct and respectively blocks the second and third air ducts. In the dust extraction mode, the switching device blocks the first air duct and turns on the third air duct; or in the dust extraction mode, the switching device blocks the first air duct and turns on the second and third air ducts.

[0081] The switching device may include a first switching unit, a second switching unit, and a driving unit. Driven by the driving unit, the first switching unit can be moved to open the first air duct and block the third air duct, and can also be moved to open the third air duct and block the first air duct. The second switching unit can be moved independently to open and block the second air duct, and when the third air duct is open, it can open or block the second air duct as needed.

[0082] Alternatively, the switching device may include a first switching unit, a second switching unit, a third switching unit, and a driving unit. Driven by the driving unit, the first switching unit can be activated to open the first air duct, while the third switching unit can be activated to block the third air duct; the third switching unit can be activated to open the third air duct while the first switching unit can be activated to block the first air duct. The second switching unit can be activated to open and block the second air duct independently, and when the third air duct is opened, it can open or block the second air duct as needed.

[0083] Furthermore, in view of the above, when in dust extraction mode, the inlet 222 can be selectively opened or closed. When the inlet 222 is opened, the dust storage chamber 221 is connected to the air inlet duct, and gas can be discharged to the outside. Conversely, when the inlet 222 is closed, the dust storage chamber 221 blocks the air inlet duct, and the gas in the dust storage chamber 221 can only be discharged to the outside through the dust outlet 225.

[0084] In one embodiment, Figures 4 to 7 As shown, the vacuum cleaner device 200 further includes an airflow reversing structure 180, which can be disposed in the housing of the air outlet portion and adjacent to the purge device 210. Preferably, the airflow reversing structure 180 is mounted below the purge device 210 to change the airflow direction of the purge device 210, so that the vacuum cleaner device 200 has a dust collection mode and a dust extraction mode.

[0085] Specifically, the airflow reversing structure 180 has a first conduction state and a second conduction state. Figure 5 As shown, in the first conduction state, the vacuum cleaner device 200 enters the dust collection mode, and the airflow reversing mechanism 180 has an airflow inlet and an airflow outlet, so that the airflow in the dust storage chamber 221 enters the airflow reversing structure 180 through the airflow inlet, and then enters the suction side 211 of the air expelling device 210, and finally is discharged to the external atmosphere from the exhaust side 212 of the air expelling device 210. A negative pressure is present in the dust storage chamber 221, and external dirt is sucked into the dust storage chamber 221.

[0086] In the second conduction state, if Figure 4 and Figure 6As shown, the vacuum cleaner device 200 enters the dust extraction mode, and the airflow reversing structure 180 has an airflow inlet and an airflow outlet. The airflow inlet is connected to the dust collecting chamber, and the air in the dust collecting chamber enters the airflow reversing structure 180 through the airflow inlet, and then enters the suction side 211 of the air purging device 210, and is discharged from the exhaust side 212 of the air purging device 210 to the airflow reversing structure 180, achieving a negative pressure in the dust collecting chamber. The air is turned in the airflow reversing structure 180, and finally discharged from the airflow outlet of the airflow reversing structure 180 and enters the dust storage chamber 221, thereby pressurizing the dust storage chamber 221 and causing the dirty water in the dust storage chamber 221 to be discharged to the outside through the dust outlet 225.

[0087] Specifically, if Figures 7 to 13 As shown, the airflow reversing structure 180 includes a reversing shell, which is provided with a first air inlet 1831, a second air inlet 1832, a first air outlet 1811 and a second air outlet 1833.

[0088] A first air flow path can be formed between the first air inlet 1831 and the first air outlet 1811. The first air inlet 1831 is connected to the dust storage chamber 221, and the first air outlet 1811 is connected to the external air. When the first air inlet 1831 and the first air outlet 1811 are connected, the air flow reversing structure 180 presents a first conduction state. Under the action of the air expelling device 210, the air in the dust storage chamber 221 can enter the first air flow path through the first air inlet 1831, and flow out from the first air outlet 1811 to the external air, causing negative pressure in the dust storage chamber 221.

[0089] A second air flow path can be formed between the second air inlet 1832 and the second air outlet 1833. The second air inlet 1832 is connected to the outside air, and the second air outlet 1833 is connected to the dust storage chamber 221. When the second air inlet 1832 and the second air outlet 1833 are connected, the air flow reversing structure 180 presents a second conduction state. Under the action of the air expelling device 210, the outside air enters the second air flow path through the second air inlet 1832, flows out from the second air outlet 1833, and then enters the dust storage chamber 221, thereby increasing the pressure in the dust storage chamber 221.

[0090] Optionally, the first air inlet 1831 and the second air inlet 1832 are disposed adjacent to the suction side 211 of the purge device 210. This shortens the airflow path of the airflow entering the purge device 210, reduces airflow loss, and improves the efficiency of suction and discharge of pollutants. Accordingly, the first air outlet 1811 and the second air outlet 1833 may also be disposed adjacent to the exhaust side 212 of the purge device 210.

[0091] Optionally, through holes are opened on the shell of the air outlet part at positions corresponding to the first air outlet 1811 and the second air inlet 1832 to facilitate external air to enter the second air inlet 1832 through the through holes, and to facilitate the air flow in the vacuum cleaner device 200 to flow to the outside through the through holes corresponding to the first air outlet 1811.

[0092] Optionally, the first air inlet 1831 and the second air outlet 1833 may be the same port or different ports; the second air inlet 1832 and the first air outlet 1811 may be the same port or different ports.

[0093] In this embodiment, an airflow reversing structure 180 is provided on the vacuum cleaner device 200. Based on the air expelling device 210 in the vacuum cleaner device 200, both the dust suction mode and the dust extraction mode can be realized, thereby making the structure of the cleaning system simpler, the cost lower, and the assembly and maintenance more convenient.

[0094] In one embodiment, Figure 4 、 Figure 7 and Figures 8-11 As shown, the reversing shell includes: a first reversing shell 181 and a second reversing shell 183. The first reversing shell 181 and the second reversing shell 183 can be set separately or as a whole. In the vertical direction, the second reversing shell 183 is located below the first reversing shell 181. The first reversing shell 181 has a hollow frame that accommodates the purge device 210, and the first air outlet 1811 is set on the first reversing shell 181. Figure 8 As shown, there may be a plurality of first air outlets 1811 , and the plurality of first air outlets 1811 are arranged at intervals on the side wall of the first reversing housing 181 .

[0095] like Figures 9 to 11 As shown, the first air inlet 1831, the second air inlet 1832 and the second air outlet 1833 are provided on the second reversing shell 183. Specifically, the second reversing shell 183 includes a concave cavity 1836 and a reversing shell 1837 surrounding the concave cavity, wherein the concave cavity 1836 and the reversing shell 1837 are spaced apart, and a first accommodating space is formed at the interval. Preferably, the concave cavity 1836 is opposite to the suction side 211 of the degassing device 210. The first air inlet 1831 is provided at the bottom of the concave cavity 1836, so that the airflow entering from the first air inlet 1831 can enter the degassing device 210 in a straight path, thereby reducing the loss of airflow. As shown Figure 11 As shown, there can be multiple first air inlets 1831 , which are spaced apart. Preferably, the multiple first air inlets 1831 are spaced apart around the same center in a fan shape, which can be the center of the bottom of the cavity 1836 .

[0096] The second air inlet 1832 is provided on the reversing housing 1837 of the second reversing housing 183, and a through hole is also provided on the side wall of the concave cavity 1836 at a position corresponding to the second air inlet 1832, so that external air can enter the concave cavity 1836 through the second air inlet 1832 and the through hole on the side wall of the concave cavity 1836, and then enter the air suction side 211 of the air purging device 210. Figure 9 As shown, there can be multiple second air inlets 1832 , which are spaced apart. Accordingly, the sidewall of the cavity 1836 is also provided with openings corresponding to the second air inlets 1832 .

[0097] The second air outlet 1833 is located on the upper surface of the second reversing housing 183 and extends downward along the axial direction of the second reversing housing 183 to the bottom of the second reversing housing 183, forming an axial air flow channel on the second reversing housing 183. Figures 9-11 As shown, the number of the second air outlets 1833 can be multiple, and the multiple second air outlets 1833 revolve around the same center of a circle and penetrate the upper and lower surfaces of the second reversing shell 183 in an arc shape, that is, the reversing shell 1837 of the second reversing shell 183 has multiple axially penetrating air flow channels.

[0098] In one embodiment, the airflow reversing structure 180 further includes a movable member that cooperates with the reversing housing of the airflow reversing structure 180 and includes a first conductive structure and a second conductive structure. When one of the first conductive structure and the second conductive structure is in a conductive state, the other is in a blocked state.

[0099] Specifically, the first conducting structure cooperates with the first air inlet 1831 and the first air outlet 1811. When the airflow reversing structure 180 is in the first conducting state, the first conducting structure can conduct the first air inlet 1831 and the first air outlet 1811, so that the first air inlet 1831 and the first air outlet 1811 are in flow, and the airflow enters the air discharging device 210 from the dust storage chamber 221. At the same time, the second conducting structure cannot conduct the second air inlet 1832 and the second air outlet 1833.

[0100] When the airflow reversing structure 180 is in the second conducting state, the second conducting structure can conduct the second air inlet 1832 and the second air outlet 1833, allowing the second air inlet 1832 and the second air outlet 1833 to circulate, and the external air enters the air purging device 210 and then enters the dust storage chamber 221. At the same time, the first conducting structure cannot conduct the first air inlet and the first air outlet.

[0101] Optionally, the first conducting structure and / or the second conducting structure can be implemented based on a solenoid valve, a connecting rod, a reciprocating mechanical structure, etc.

[0102] In this embodiment, a movable part is provided in the airflow reversing structure, and two airflow paths can be realized through the airflow reversing structure alone, thereby greatly simplifying the structure of the vacuum cleaner device.

[0103] In one embodiment, Figure 7 、 Figures 12 and 13 As shown, the first conductive structure includes a first docking port 1841 and a second docking port 1821, and the second conductive structure includes a third docking port 1842 and a fourth docking port 1843. The first docking port 1841 is used to dock with the first air inlet 1831, the second docking port 1821 is used to dock with the first air outlet 1811, the third docking port 1842 is used to dock with the second air inlet 1832, and the fourth docking port 1843 is used to dock with the second air outlet 1833.

[0104] Specifically, when the airflow reversing structure 180 is in the first conduction state, the first docking interface 1841 and the first air inlet 1831 are connected and docked, and the second docking interface 1821 and the first air outlet 1811 are connected and docked. At the same time, the third docking interface 1842 and the second air inlet 1832 cannot be connected and docked, and the fourth docking interface 1843 and the second air outlet 1833 cannot be connected and docked, so that the airflow flows out from the dust storage chamber 221 to the air expelling device 210 through the first air inlet 1831, but cannot enter the dust storage chamber 221 from the air expelling device 210 through the second air inlet 1832.

[0105] Correspondingly, when the airflow reversing structure 180 is in the second conduction state, the first docking interface 1841 and the first air inlet 1831 cannot be connected and docked, and the second docking interface 1821 and the first air outlet 1811 cannot be connected and docked. At the same time, the third docking interface 1842 and the second air inlet 1832 are connected and docked, and the fourth docking interface 1843 and the second air outlet 1833 are connected and docked, so that external air enters the air expelling device 210 through the second air inlet 1832, and then flows out to the dust storage chamber 221 through the second air outlet 1833.

[0106] In one embodiment, referring to Figure 7 、 Figures 12 and 13 The movable member includes a first movable member 182 and a second movable member 184. The first movable member 182 is configured to cooperate with the first reversing housing 181, sleeved on the outside of the first reversing housing 181, and can cover the first air outlet 1811. The second docking port 1821 is provided on the first movable member 182. If the first reversing housing 181 is provided with multiple first air outlets 1811, the first movable member 182 is also provided with multiple second docking ports 1821 accordingly.

[0107] Second movable member 184 is cooperable with second reversing housing 183. Second movable member 184 is open at the top and bottom, with its outer wall divided by a partition 1847 into a first portion and a second portion (not shown). The first portion is positioned above the second portion. The first portion and partition 1847 form a second accommodating space. Concave cavity 1836 of second reversing housing 183 is accommodated in the second accommodating space, with partition 1847 facing the bottom of cavity 1836.

[0108] The first docking port 1841 is provided on the partition 1847, and its shape and size can be adapted to the first air inlet 1831. For example, if the first air inlet 1831 is square, the first docking port 1841 also adopts a square shape of the same size, so that the airflow can be transmitted to the purge device 210 as much as possible, reducing airflow loss. Of course, in the case where there are multiple first air inlets 1831, there are also multiple first docking ports 1841, and the multiple first docking ports 1841 correspond one-to-one to the multiple first air inlets 1831.

[0109] The outer wall of the first portion of the second movable member 184 is adapted to be accommodated in the first accommodation space formed between the reversing housing 1837 and the concave cavity 1836 of the second reversing housing 183 , that is, the second movable member 184 and the second reversing housing 183 can be assembled in a plug-in manner.

[0110] The third docking port 1842 is arranged on the outer wall of the first part to dock with the second air inlet 1832 on the second reversing shell 183. Its shape and size can be adapted to the second air inlet 1832. For example, the second air inlet 1832 is set to a square, and the third docking port 1842 also adopts a square of the same size, thereby reducing airflow loss.

[0111] Fourth docking port 1843 is disposed on the outer wall of the second portion to mate with second air outlet 1833 of second reversing housing 183. In this embodiment, the airflow channel extending axially from second air outlet 1833 comprises an outer wall and an inner wall, wherein the inner wall is shorter than the outer wall, i.e., the inner wall does not reach the bottom of fourth docking port 1843. Consequently, after second movable member 184 and second reversing housing 183 are assembled, fourth docking port 1843 is not covered by the inner wall, thereby preventing airflow from being blocked.

[0112] In one embodiment, Figure 7As shown, the first reversing shell 181, the second reversing shell 183, the first movable part 182 and the second movable part 184 are coaxial. A shock-absorbing pad, a sound-absorbing cotton and other structures are provided between the first reversing shell 181 and the air purging device 210, so as to reduce the vibration and noise caused by the operation of the air purging device 210. A first sealing structure 186 can be provided between the first reversing shell 181 and the first movable part 182 to seal the gap between the first reversing shell 181 and the first movable part 182, and the first sealing structure 186 can be an integrated structure. A second sealing structure 187 can be provided between the second reversing shell 183 and the second movable part 184 for sealing. The gap between the second reversing shell 183 and the second movable part 184, the second sealing structure 187 can be an integrated structure.

[0113] In one embodiment, the airflow reversing structure 180 includes a reversing drive assembly, which may include a reversing drive member 185 and a reversing transmission member drivingly connected to the reversing drive member 185. The reversing transmission member is in driving connection with the movable member, and under the action of the reversing drive member 185, the movable member is driven to move, causing the airflow reversing structure 170 to assume a first conductive state or a second conductive state. The reversing drive member 185 may be a motor.

[0114] Specifically, if Figure 4 、 Figure 7 、 Figure 8 、 Figure 12 and Figure 13 As shown, the reversing transmission member includes a first transmission member 1822 and a second transmission member 1823. The first transmission member 1822 and the second transmission member 1823 are arranged on the first movable member 182. The first transmission member 1822 is used to drive the first movable member 182 to rotate, and the second transmission member 1823 is used to drive the second movable member 184 to rotate.

[0115] The first transmission member 1822 can be a gear, a transmission belt, etc. Taking a gear as an example, the output end of the reversing drive member 185 is provided with a gear structure adapted to the first transmission member 1822. When the reversing drive member 185 is working, the gear structure can drive the first movable member 182 to rotate.

[0116] The second transmission member 1823 is in transmission connection with the second movable member 184. The second transmission member 1823 can be a rib extending to the second movable member 184, and the rib is provided with a first mating portion (not shown in the figure). The second movable member 184 is provided with a second mating portion 1846 that locks with the first mating portion. When the reversing drive member 185 drives the first movable member 182 to rotate, the second transmission member 1823 rotates accordingly, and the second movable member 184, driven by the first mating portion and the second mating portion 1846, also rotates accordingly, thereby causing the airflow reversing structure 180 to present the first conductive state or the second conductive state.

[0117] Alternatively, as Figure 7 and Figure 8 As shown, the first reversing housing 181 is provided with an outer protrusion 1812 , which has an accommodating groove suitable for accommodating the reversing driving member 185 .

[0118] By adopting the above-mentioned driving reversing assembly, two movable parts can be driven to rotate synchronously under the drive of a reversing driving part, which saves costs and has a simple structure.

[0119] In one embodiment, Figure 10 As shown, the airflow reversing structure 180 further includes a limiting structure 1834 disposed on the second reversing housing 183. A second mating portion 1846 can extend from the limiting structure 1834 to limit the maximum rotation angle of the reversing drive member 185, the first movable member 182, and the second movable member 184 through the engagement of the second mating portion 1846 with the limiting structure 1834, thereby preventing malfunction of the airflow reversing structure 180 due to, for example, a malfunction of the reversing drive member 185.

[0120] In one embodiment, Figure 12 and 13 As shown, first movable member 182 is provided with a second blocking structure 1824, which is used to block first air outlet 1811. Second blocking structure 1824 can be disposed adjacent to second docking port 1821. If there are multiple first air outlets 1811 and multiple second docking ports 1821, there can also be multiple second blocking structures 1824, with multiple second blocking structures 1824 formed between adjacent first docking ports 1821.

[0121] The second movable member 184 is provided with a first blocking structure 1844, a third blocking structure 1845 and a fourth blocking structure 1848.

[0122] The first blocking structure 1844 is disposed adjacent to the first docking port 1841 to block the first air inlet 1831. If there are multiple first air inlet 1831 and multiple first docking ports 1841, there are also multiple first blocking structures 1844, each formed between two adjacent first docking ports 1841.

[0123] The third blocking structure 1845 is disposed adjacent to the third docking port 1842 and is configured to block the second air inlet 1832. If there are multiple second air inlet 1832 and multiple third docking ports 1842, there are also multiple third blocking structures 1845, with the multiple third blocking structures 1845 formed between two adjacent third docking ports 1842.

[0124] The fourth blocking structure 1848 is disposed adjacent to the fourth docking port 1843 and is configured to block the second air outlet 1833. If there are multiple second air outlets 1833 and multiple fourth docking ports 1843, there are also multiple fourth blocking structures 1848, with the multiple fourth blocking structures 1848 formed between two adjacent fourth docking ports 1843.

[0125] Specifically, the airflow reversing structure 180 further includes a position sensor (not shown in the figure), which can be implemented using a micro switch, a Hall sensor, etc. When the vacuum cleaner device 200 enters the vacuuming mode, if the control device on the vacuum cleaner device 200 determines that the airflow reversing structure 180 is not currently in the first conduction state based on the position detection signal of the position sensor, it controls the reversing drive member 185 to rotate by a preset angle in the first direction to drive the first movable member 182 and the second movable member 184 to rotate synchronously, so that the airflow reversing structure 180 enters the first conduction state. At this time, the third blocking structure 1845 on the second movable member 184 blocks the second air inlet 1832, and the fourth blocking structure 1848 blocks the second air outlet 1833, thereby preventing external air from entering the vacuum cleaner device 200. At the same time, the second docking port 1821 on the first movable part 182 docks with the first air outlet 1811 on the first reversing shell 181, and the first docking port 1841 on the second movable part 184 docks with the first air inlet 1831 at the bottom of the second reversing shell 183, so that the air in the dust storage chamber 221 can enter the air expelling device 210 from the first air inlet 1831, and be discharged to the external environment from the first air outlet 1811 on the side wall of the first reversing shell 181.

[0126] Correspondingly, when the vacuum cleaner device 200 enters the dust extraction mode, if the control device determines that the airflow reversing structure 180 is not currently in the second conduction state based on the position detection signal of the position sensor, the reversing drive member 185 is controlled to rotate a preset angle in the second direction, driving the first movable member 182 and the second movable member 184 to rotate synchronously, so that the airflow reversing structure 180 presents the second conduction state. At this time, the second blocking structure 1824 on the first movable member 182 is docked with the first air outlet 1811 on the first reversing shell 181; the first blocking structure 1844 on the second movable member 184 is docked with the first air inlet 1831 at the bottom of the second reversing shell 183 to block the airflow outflow path of the dust storage chamber 221. At the same time, the third docking port 1842 on the second movable part 184 docks with the second air inlet 1832 on the second reversing shell 183, and the fourth docking port 1843 on the second movable part 184 docks with the second air outlet 1833 on the second reversing shell 183, so that external air flows from the second air inlet 1832 to the air flow reversing structure 180, and passes through the air venting device 210 to reach the dust storage chamber 221, thereby prompting the sewage in the dust storage chamber 221 to be discharged.

[0127] The first direction and the second direction are opposite directions. For example, the first direction is counterclockwise, and the second direction is clockwise.

[0128] In this embodiment, by providing a position sensor and a blocking structure, the airflow reversing structure can be fully automatically controlled based on the circuit system of the position sensor, the control device and the drive motor, thereby improving the intelligence level of the vacuum cleaner equipment.

[0129] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
