[0050] The present invention provides a vacuum cleaner system 1000. Specifically, please refer to Figures 1 to 3In this embodiment, the vacuum cleaner system 1000 includes a dust collecting station 200 and a vacuum cleaner device 100, and the dust collecting station 200 is provided with a sewage discharge channel 12; the vacuum cleaner device 100 includes a suction device 104, a dust cup assembly 103, and an air duct switching structure 102, and the dust cup assembly 103 is provided with a sewage discharge port 1032 that is connected to the sewage discharge channel 12; when the vacuum cleaner device 100 is connected to the dust collecting station 200 or after being connected, the air duct switching structure 102 is in a first working state that connects the suction device 104 and the dust collecting station 200, so that a negative pressure is formed in the dust collecting station 200 at least in the sewage discharge channel 12; wherein, the vacuum cleaner device 100 is placed on the dust collecting station 200 along a first direction, and the sewage discharge port 1032 is arranged outward along the first direction. Here, outward refers to a direction relative to the vacuum cleaner device 100 itself, that is, a direction toward the outside of the vacuum cleaner device 100 , and the sewage outlet 1032 may be exposed to facilitate sewage discharge.

[0051] In this embodiment, when the vacuum cleaner device 100 works alone, the suction device 104 can provide suction power to suck external dirt into the dust cup assembly 103 to achieve cleaning. When the vacuum cleaner device 100 has finished working, the vacuum cleaner device 100 can be connected to the dust collection station 200, and the air duct switching structure 102 on the vacuum cleaner device 100 can be used to connect the suction device 104 to the dust collection station 200, so that negative pressure is formed in the dust collection station 200, and at least in the sewage discharge channel 12 of the dust collection station 200, so that the dust cup is sucked into the dust cup assembly 103 through the sewage discharge channel 12. The dirt stored in the component 103 is sucked out to achieve self-cleaning of the dust cup component 103; moreover, when the vacuum cleaner device 100 is connected to the dust collecting station 200, it can be placed on the dust collecting station 200 along the first direction, and the sewage outlet 1032 on the dust cup component 103 is also set outward along the first direction, that is, the sewage outlet 1032 can be better oriented towards the sewage channel 12. When discharging sewage, the wind resistance in the passage between the sewage channel 12 and the sewage outlet 1032 is smaller, so that the sewage discharge efficiency is better, and the self-cleaning of the dust cup component 103 can be achieved faster and more efficiently.

[0052] It is understood that the first direction can be an up-down direction, a horizontal direction, or a curved direction, so that when the vacuum cleaner device 100 is placed on the dust collection station 200, the dust cup assembly 103 is easily placed, and the vacuum cleaner device 100 is placed more stably on the dust collection station 200.

[0053] Preferably, a accommodating chamber 11 is formed in the dust collection station 200. At least a portion of the dust cup assembly 103 can be accommodated within the accommodating chamber 11, so that the drain outlet 1032 is located within the accommodating chamber 11. This allows waste to fall more easily into the accommodating chamber 11 during discharge, preventing leakage. The accommodating chamber 11 has an upward-facing opening, with the first direction being from top to bottom. The drain outlet 1032 is located at the bottom of the dust cup assembly 103. When the drain outlet 1032 of the dust cup assembly 103 is opened, some waste can fall into the dust collection station 200 under its own gravity, making waste discharge more convenient.

[0054] Further, if Figure 4 As shown in the figure, the dust collection station 200 also includes a dirt storage chamber 2, and the sewage discharge channel 12 connects the sewage discharge channel 12 and the dirt storage chamber 2. The dirt in the dust cup assembly 103 is introduced into the dirt storage chamber 2 through the sewage discharge channel 12 to achieve the cleaning of the dust cup assembly 103.

[0055] Of course, in another embodiment, there is no need to set up the sewage storage chamber 2 on the dust collecting station 200, and the sewage discharge channel 12 is directly connected to the sewer, so that the sewage can be discharged directly into the sewer without the need to clean the sewage storage chamber 2 in the sewage collection chamber. This is more convenient, and the size of the dust collecting station 200 can be smaller.

[0056] The accommodating chamber 11 may be formed on the main body of the dust collecting station 200, or the accommodating chamber 11 may be a separate component to facilitate maintenance. Figure 4 As shown in , the dust collecting station 200 includes a sewage guide barrel 1, which includes a first barrel section and a second barrel section that are connected to each other. The inner cavity of the first barrel section forms a receiving chamber 11, and the inner cavity of the second barrel section forms a sewage discharge channel 12. The sewage storage chamber 2 is provided with a sewage inlet 21, and the second barrel section is connected to the sewage inlet 21. The receiving chamber 11 and the sewage discharge channel 12 are arranged as one body, and there is no connecting gap between the receiving chamber 11 and the sewage discharge channel 12. Dirt is not easily retained in the receiving chamber 11 or the sewage discharge channel 12, and it is not easy to retain dirt. Moreover, the sewage guide barrel 1 is a separate component, so that the sewage guide barrel 1 can be easily disassembled and maintained, and the sewage guide barrel 1 is also easier to clean.

[0057] When the vacuum cleaner device 100 is placed on the dust collection station 200, the sewage outlet 1032 is located at the transition between the first barrel section and the second barrel section. After the sewage outlet 1032 is opened, the dirt can fall directly into the second barrel section and be directly introduced into the sewage storage chamber 2 through the second barrel section, which has a higher sewage guiding efficiency.

[0058] Moreover, combined Figure 4 and Figure 5As shown, the dust collection station 200 further includes a cover structure 3, which is movably mounted at the sewage inlet 21 and can open and close the sewage inlet 21. When the vacuum cleaner device 100 is placed on the dust collection station 200, the cover structure 3 can open the sewage inlet 21, and the dirt entering the second barrel section can fall into the sewage storage chamber 2 through the sewage inlet 21. When the vacuum cleaner device 100 is removed from the dust collection station 200, the sewage inlet 21 can be sealed by the cover structure 3 to prevent the dirt in the dust collection station 200 from emitting odor through the sewage inlet 21, thereby better protecting the user environment.

[0059] Preferably, if Figure 5 As shown in the figure, the cover structure 3 includes a mounting plate 31 and a cover plate 32. The mounting plate 31 is connected to the dirt storage chamber 2 and is located on the inner side of the dirt storage chamber 2. The mounting plate 31 is provided with a through hole connected to the dirt inlet 21; the cover plate 32 is movably provided at the through hole and can open and close the through hole; wherein, when negative pressure is formed in the dirt storage chamber 2, the cover plate 32 can move under the action of the negative pressure to open the through hole, and when the negative pressure in the dirt storage chamber 2 is removed, the cover plate 32 can automatically reset to close the through hole. Specifically, the cover plate 32 can be a unidirectional elastic rubber plate. The cover plate 32 is arranged to cover the sewage inlet 21. After the suction device 104 is connected to the sewage storage chamber 2, the suction device 104 creates a negative pressure in the sewage storage chamber 2. Under the action of the negative pressure, the cover plate 32 is turned downward toward the sewage storage chamber 2 to open the sewage inlet 21. The dirt in the dust cup assembly 103 can be sucked into the sewage storage chamber 2 under the action of the negative pressure, thereby achieving self-cleaning of the dust cup chamber 1031. After the dirt in the dust cup assembly 103 is cleaned, the suction device 104 can stop working, and the negative pressure is no longer formed in the sewage storage chamber 2. The cover plate 32 can then be reset under the action of its own elastic deformation force to re-seal the sewage inlet 21 and prevent the discharge of odor.

[0060] Since the cover structure 3 may fail to rotate after a long period of operation, or dirt may remain on the cover plate 32, in order to facilitate the maintenance and cleaning of the cover structure 3, specifically, one side of the dirt storage chamber 2 is opened, and the dust collection station 200 also includes a detachable dirt storage plate provided on the open side of the dirt storage chamber 2. By removing the dirt storage plate, the inner cavity of the dirt storage chamber 2 can be exposed, thereby facilitating the cleaning of the inner side of the dirt storage chamber 2. In addition, a limiting rib is provided on the inner side of the dirt storage chamber 2. The limiting rib and the inner wall of the dirt storage chamber 2 form a limiting groove. The limiting rib extends from the open side of the dirt storage chamber 2 into the dirt storage chamber 2. The mounting plate 31 can be inserted into the limiting groove from the open side of the dirt storage chamber 2 and abutted between the dirt storage plate and the inner side wall of the dirt storage chamber 2 opposite to the open side. The mounting plate 31 is limited in the vertical direction by the limiting ribs, and is limited in the horizontal direction by the two opposite inner walls of the dirt storage chamber 2, so that the mounting plate 31 is completely fixed and the disassembly and assembly of the mounting plate 31 is also convenient.

[0061] In addition, a flange protrudes from the side of the dirt storage chamber 2 facing the dust cup assembly 103, and the flange is arranged around the outer periphery of the dirt inlet 21. The dust collection station 200 also includes a sealing ring 33, which is mounted on the inner side of the flange and abuts the mounting plate 31. At least a portion of the second barrel section is inserted into the inner side of the sealing ring 33. The sealing ring 33 seals the second barrel section and the dirt inlet 21, preventing dust from leaking out of the accommodating chamber 11. Of course, the dirt storage chamber 2 is also provided with an air outlet 22, which is connected to the air duct switching structure 102 through the air outlet 22, so that the suction device 104 can communicate with the dirt storage chamber 2.

[0062] The vacuum cleaner device 100 further includes a device body 101 , and the device body 101 includes a shell, through which the suction device 104 and the air duct switching structure 102 can be covered for better protection.

[0063] For the dust cup assembly 103, Figure 2 and Figure 3 As shown, the dust cup assembly 103 includes a dust cup cavity 1031 and a dust cup cover 1033 provided on the dust cup cavity 1031. The dust cup cavity 1031 has a dust outlet. The dust cup cover 1033 is movably arranged to open and close the dust outlet. By opening the dust cup cover 1033, the dirt in the dust cup cavity 1031 can be poured out. When the vacuum cleaner device 100 is not connected to the dust collection station 200, the dirt can also be poured out through the dust outlet, and the dust cup cavity 1031 can be cleaned.

[0064] It can be understood that the dust outlet and the sewage outlet 1032 can be set as two different openings, so as to be used for cleaning different dust cup cavities 1031 of the vacuum cleaner device 100 respectively.

[0065] When the dust outlet and the sewage outlet 1032 are two different openings, the dust outlet and the sewage outlet 1032 can be located on different sides of the dust cup cavity 1031. For example, the sewage outlet 1032 is located at the bottom of the dust cup cavity 1031, and the dust outlet can be located on the side wall of the dust cup cavity 1031. Of course, the dust outlet and the sewage outlet 1032 can also be located on the same side of the dust cup cavity 1031 so that the discharge direction of the dirt is consistent.

[0066] Preferably, the dust outlet and the sewage outlet 1032 are integrally arranged, that is, the dust outlet and the sewage outlet 1032 are the same opening. After opening the dust cup cover 1033, the dirt can be discharged from the sewage outlet 1032, so that the dirt can be directly dumped through the vacuum cleaner device 100 or the dirt in the dust cup assembly 103 can be sucked out through the dust collection station 200, so that the structure of the vacuum cleaner device 100 can also be simpler.

[0067] Among them, such as Figure 3As shown in the figure, the dust cup assembly 103 also includes a first filtering structure 1034 and a second filtering structure 1035. The first filtering structure 1034 is cylindrical and is arranged on the inner side of the dust cup cavity 1031. The gap between the first filtering structure 1034 and the dust cup cavity 1031 forms a first dust collection channel; the second filtering structure 1035 is arranged on the inner side of the first filtering structure 1034, and a second dust collection channel is formed on the second filtering structure 1035; the first dust collection channel and the second dust collection channel are both connected to the dust outlet, and the dust cup cover 1033 can simultaneously close the first dust collection channel and the second dust collection channel. The dirt filtered out from the first filtering structure 1034 can flow to the dust outlet, and the dirt filtered out from the second filtering structure 1035 can also flow toward the dust outlet, so that the dirt filtered out by each level of filtering structure can be discharged from the dust outlet, thereby more thoroughly discharging the dirt. Moreover, the first dust collection channel and the second dust collection channel can be blocked by the dust cup cover 1033 at the same time. The number of dust cup covers 1033 is smaller and the structure is simpler. Therefore, when discharging sewage, only one dust cup cover 1033 needs to be opened to discharge all the dirt, and the sewage discharge effect is better.

[0068] Preferably, combined Figure 2 and Figure 3 As shown, the first filter structure 1034 and the second filter structure 1035 are both coaxially arranged with the dust cup chamber 1031. After the vacuum cleaner device 100 is placed on the dust collection station 200, the center of gravity is better aligned with the accommodating chamber 11, thereby providing a more stable placement. Furthermore, the axial direction of the first filter structure 1034 and the axial direction of the second filter structure 1035 are perpendicular to the axial direction of the air inlet end of the suction device 104. The suction device 104 may be provided with an axial flow fan, the rotating axis of the axial flow fan's impeller being arranged horizontally, the axial direction of the dust cup chamber 1031 being arranged vertically, and the suction device 104 being arranged above the dust cup chamber 1031. This allows the center of gravity of the entire vacuum cleaner device 100 to be more centered horizontally. Therefore, when the vacuum cleaner device 100 is placed on the dust collection station 200 from top to bottom, the vacuum cleaner device 100 is more stable on the dust collection station 200 and is less likely to tip over.

[0069] More preferably, Figure 4 As shown in FIG, the dust cup assembly 103, the sewage outlet 1032, and the sewage inlet 21 are all coaxially arranged. When the air duct switching structure 102 is in the first working state, the suction device 104 on the vacuum cleaner device 100 is connected to the sewage storage chamber 2. The airflow can better flow from the dust cup assembly 103 to the sewage outlet 1032 and the sewage inlet 21 to bring the dirt into the sewage storage chamber 2. The airflow encounters less wind resistance, thereby improving the sewage discharge efficiency.

[0070] As for the air duct switching structure 102, it is mainly used to switch the working state of the vacuum cleaner device 100, so that the suction device 104 can be better connected with the dust cup assembly 103 or better connected with the dust collection station 200200. Specifically, Figure 3 As shown in the figure, a first channel and a second channel are formed on the device body 101; the first channel connects the suction device 104 and the dust cup assembly 103, and the second channel is suitable for connecting the suction device 104 and the dust collection station 200200; the air duct switching structure 102 includes a first shielding part 1021 and a second shielding part 1022 which are movably arranged, the first shielding part 1021 is used to block and conduct the first channel, and the second shielding part 1022 is used to block and conduct the second channel, and the first shielding part 1021 and the second shielding part 1022 are movable to have a first working state of blocking the first channel and conducting the second channel, and a second working state of conducting the first channel and blocking the second channel.

[0071] The first channel has a first opening connected to the suction device 104, and the second channel has a second opening connected to the suction device 104; when in the first working state, the first blocking portion 1021 blocks the first opening, and the second blocking portion 1022 opens the second opening; when in the second working state, the first blocking portion 1021 opens the first opening, and the second blocking portion 1022 blocks the second opening.

[0072] Further, if Figure 3 As shown, the air duct switching structure 102 further includes a first transmission member 1023 movably disposed within the device body 101. The first transmission member 1023 connects the first shielding portion 1021 and the second shielding portion 1022. When the first transmission member 1023 is moved by an external force, it drives the first shielding portion 1021 and the second shielding portion 1022 to move together. The first transmission member 1023 can be moved manually, or by a driving device, or alternatively, by the dust collection station 200200, thereby switching the first shielding portion 1021 and the second shielding portion 1022 between the operating states and better ensuring the working performance of the vacuum cleaner device 100.

[0073] When the first transmission member 1023 reciprocates linearly and the first shielding portion 1021 and the second shielding portion 1022 are two separate components, the first shielding portion 1021 is used to block and open the first opening, and the second shielding portion 1022 is used to block and open the second opening. Specifically, the first transmission member 1023 includes a first transmission rod, the first shielding portion 1021 and the second shielding portion 1022 are arranged at intervals along the length of the first transmission rod, and the first transmission rod is movably mounted within the first opening and the second opening.
