[0054] The present disclosure provides a dust collector system 1000, specifically, referring to FIGS. 1-3, in the embodiment, the dust collector system 1000 comprises a dust collecting station 200 and a dust collector device 100, the dust collecting station 200 is provided with a dirt discharging channel 12; the dust collector device 100 comprises a suction device 104, a dust cup assembly 103, and an air duct switching structure 102, the dust cup assembly 103 is provided with a dirt discharging opening 1032 communicated with the dirt discharging channel 12; when or after the dust collector device 100 is connected with the dust collecting station 200, the air duct switching structure 102 is in a first working state of communicating 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 dirt discharging channel 12; wherein the dust collector device 100 is placed on the dust collecting station 200 along a first direction, and the dirt discharging opening 1032 is outwardly arranged along the first direction. Here, outwardly is relative to the dust collector device 100 itself, and is a direction towards the outside of the dust collector device 100, the dirt discharging opening 1032 can be exposed, so as to facilitate dirt discharging.

[0055] In the embodiment, when the dust collector device 100 works alone, the suction device 104 can provide suction power to suck external dirt into the dust cup assembly 103, so as to realize cleaning work; when the dust collector device 100 works, the dust collector device 100 can be connected with the dust collecting station 200, and the air duct switching structure 102 on the dust collector device 100 can make the suction device 104 communicated with the dust collecting station 200, so that a negative pressure is formed in the dust collecting station 200 at least in the dirt discharging channel 12 of the dust collecting station 200, thereby the dirt stored in the dust cup assembly 103 is sucked out through the dirt discharging channel 12, so as to realize self-cleaning of the dust cup assembly 103; moreover, when the dust collector device 100 is connected with the dust collecting station 200, the dust collector device 100 can be placed on the dust collecting station 200 along the first direction, and the dirt discharging opening 1032 on the dust cup assembly 103 is also outwardly arranged along the first direction, i.e. the dirt discharging opening 1032 can be better directed to the dirt discharging channel 12, and the air resistance in the passage between the dirt discharging channel 12 and the dirt discharging opening 1032 is smaller, so that the dirt discharging efficiency is better, and the self-cleaning of the dust cup assembly 103 can be realized more quickly and efficiently.

[0056] It can be understood that the first direction can be an up-down direction, or a horizontal direction, or a curved direction, so that the dust collector device 100 is placed on the dust collecting station 200, and the dust cup assembly 103 is placed more stably.

[0057] Preferably, the dust collecting station 200 is provided with a receiving cavity 11, at least part of the dust cup assembly 103 is received in the receiving cavity 11, so that the dirt outlet 1032 is arranged in the receiving cavity 11, so that the dirt can fall into the receiving cavity 11 better without leakage when discharging. The receiving cavity 11 has a cavity opening arranged upward, the first direction is a downward direction, and the dirt outlet 1032 is arranged at the bottom of the dust cup assembly 103. When the dirt outlet 1032 of the dust cup assembly 103 is opened, a part of the dirt can fall into the dust collecting station 200 under the action of gravity, and the dirt discharge is more convenient.

[0058] Further, as shown in FIG. 4, the dust collecting station 200 further includes a dirt storage cavity 2, and the dirt discharge channel 12 is communicated with the dirt storage cavity 2. The dirt in the dust cup assembly 103 is guided into the dirt storage cavity 2 through the dirt discharge channel 12, so as to realize the cleaning of the dust cup assembly 103.

[0059] Of course, in another embodiment, the dirt storage cavity 2 can not be arranged on the dust collecting station 200, and the dirt discharge channel 12 is directly communicated with the sewer, so that the dirt can be directly discharged into the sewer without cleaning the dirt storage cavity 2 in the dirt collecting cavity, which is more convenient, and the volume of the dust collecting station 200 can be smaller.

[0060] The receiving cavity 11 can be formed on the main body of the dust collecting station 200, or the receiving cavity 11 can be a separate component for easy maintenance. Specifically, as shown in FIG. 4, the dust collecting station 200 includes a dirt guiding cylinder 1, the dirt guiding cylinder 1 includes a first cylinder segment and a second cylinder segment communicated with each other, the inner cavity of the first cylinder segment forms the receiving cavity 11, the inner cavity of the second cylinder segment forms the dirt discharge channel 12, the dirt storage cavity 2 is provided with a dirt inlet 21, and the second cylinder segment is communicated with the dirt inlet 21. The receiving cavity 11 and the dirt discharge channel 12 are arranged integrally, and there is no connection gap between the receiving cavity 11 and the dirt discharge channel 12, so that the dirt is not easy to stay in the receiving cavity 11 or the dirt discharge channel 12, and the dirt is not easy to stay. Moreover, the dirt guiding cylinder 1 is a separate component, so that the dirt guiding cylinder 1 can be easily disassembled and maintained, and the dirt guiding cylinder 1 is also easy to clean.

[0061] When the dust collector device 100 is placed on the dust collecting station 200, the dirt outlet 1032 is located at the transition of the first cylinder segment and the second cylinder segment. After the dirt outlet 1032 is opened, the dirt can directly fall into the second cylinder segment, and the dirt can be directly guided into the dirt storage cavity 2 through the second cylinder segment, so that the dirt guiding efficiency is higher.

[0062] Moreover, as shown in FIG. 4 and FIG. 5, the dust collecting station 200 further comprises a cover structure 3 movably arranged at the dirt inlet 21 and capable of opening and closing the dirt inlet 21. When the dust collector 100 is placed on the dust collecting station 200, the cover structure 3 can open the dirt inlet 21, and the dirt in the second cylinder section can fall into the dirt storage cavity 2 through the dirt inlet 21. When the dust collector 100 is removed from the dust collecting station 200, the cover structure 3 can close the dirt inlet 21, so as to avoid the odor of the dirt in the dust collecting station 200 from being emitted through the dirt inlet 21, and better protect the use environment.

[0063] Preferably, as shown in FIG. 5, the cover structure 3 comprises a mounting plate 31 and a cover plate 32. The mounting plate 31 is connected with the dirt storage cavity 2 and located at the inner side of the dirt storage cavity 2. The mounting plate 31 is provided with a through hole in communication with the dirt inlet 21. The cover plate 32 is movably arranged at the through hole and capable of opening and closing the through hole. When the negative pressure is formed in the dirt storage cavity 2, the cover plate 32 can be moved under the action of the negative pressure to open the through hole. When the negative pressure in the dirt storage cavity 2 is removed, the cover plate 32 can be automatically reset to close the through hole. Specifically, the cover plate 32 can be a one-way elastic rubber plate. The cover plate 32 is arranged at the dirt inlet 21. After the suction device 104 is connected with the dirt storage cavity 2, the negative pressure is formed in the dirt storage cavity 2 through the suction device 104. Then, under the action of the negative pressure, the cover plate 32 is rotated downward toward the dirt storage cavity 2 to open the dirt inlet 21. The dirt in the dust cup assembly 103 can be sucked into the dirt storage cavity 2 under the action of the negative pressure, so as to realize the self-cleaning of the dust cup cavity 1031. After the dirt in the dust cup assembly 103 is cleaned, the suction device 104 can stop working, the negative pressure is not formed in the dirt storage cavity 2, and the cover plate 32 can be reset under the action of the elastic deformation force of the cover plate 32 to reseal the dirt inlet 21, so as to avoid the odor from being emitted.

[0064] Since the cover structure 3 can be rotated invalidly after a long time of work, or the dirt can be left on the cover plate 32, the maintenance and cleaning of the cover structure 3 are facilitated. Specifically, one side of the dirt storage cavity 2 is arranged in an open manner. The dust collecting station 200 further comprises a detachable dirt storage plate arranged at the open side of the dirt storage cavity 2. The inner cavity of the dirt storage cavity 2 can be exposed by detaching the dirt storage plate, so as to facilitate the cleaning of the inner side of the dirt storage cavity 2. Moreover, a limiting protrusion is arranged at the inner side of the dirt storage cavity 2. The limiting protrusion and the inner wall of the dirt storage cavity 2 form a limiting groove. The limiting protrusion is arranged to extend from the open side of the dirt storage cavity 2 toward the inner side of the dirt storage cavity 2. The mounting plate 31 can be inserted into the limiting groove from the open side of the dirt storage cavity 2 and abut between the dirt storage plate and the inner side wall of the dirt storage cavity 2 opposite to the open side. The limiting protrusion limits the mounting plate 31 in the up-down direction, and the two opposite inner walls of the dirt storage cavity 2 limit the mounting plate 31 in the horizontal direction, so as to completely fix the mounting plate 31, and the mounting plate 31 is convenient to detach and assemble.

[0065] In addition, a flange is arranged on the side of the dirt storage cavity 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 further comprises a sealing ring 33, which is arranged on the inner side of the flange and abuts against the mounting plate 31, and at least part of the second cylinder segment is inserted into the inner side of the sealing ring 33. The sealing ring 33 can seal between the second cylinder segment and the dirt inlet 21, so as to prevent dust from leaking out from the side of the dirt storage cavity 11. Of course, the dirt storage cavity 2 is also provided with an air outlet 22, which is in communication with the air duct switching structure 102, so that the suction device 104 can be in communication with the dirt storage cavity 2.

[0066] The dust collector device 100 further comprises a device main body 101, which comprises a shell, and the suction device 104 and the air duct switching structure 102 are covered in the shell, thereby being better protected.

[0067] For the dust cup assembly 103, as shown in FIGS. 2 and 3, the dust cup assembly 103 comprises a dust cup cavity 1031 and a dust cup cover 1033 arranged on the dust cup cavity 1031, the dust cup cavity 1031 has a dust outlet, and the dust cup cover 1033 is arranged to be movable 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, and when the dust collector 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.

[0068] It can be understood that the dust outlet and the dirt outlet 1032 can be arranged as two different openings for different cleaning modes of the dust cup cavity 1031 of the dust collector device 100.

[0069] When the dust outlet and the dirt outlet 1032 are two different openings, the dust outlet and the dirt outlet 1032 can be located on different sides of the dust cup cavity 1031, for example, the dirt 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 dirt outlet 1032 can also be located on the same side of the dust cup cavity 1031, so that the dirt is discharged in the same direction.

[0070] Preferably, the dust outlet and the dirt outlet 1032 are integrally arranged, that is, the dust outlet and the dirt outlet 1032 are the same opening. After the dust cup cover 1033 is opened, the dirt can be discharged from the dirt outlet 1032, so as to directly pour the dirt through the dust collector device 100 or to suck the dirt in the dust cup assembly 103 through the dust collection station 200, so that the structure of the dust collector device 100 can also be simpler.

[0071] As shown in FIG. 3, the dust cup assembly 103 further comprises a first filtering structure 1034 and a second filtering structure 1035. The first filtering structure 1034 is cylindrically arranged and is arranged inside the dust cup cavity 1031. The space between the first filtering structure 1034 and the dust cup cavity 1031 forms a first dust falling channel. The second filtering structure 1035 is arranged inside the first filtering structure 1034. The second filtering structure 1035 is provided with a second dust falling channel. The first dust falling channel and the second dust falling channel are both connected to the dust outlet. The dust cup cover 1033 can simultaneously seal the first dust falling channel and the second dust falling channel. The dirt filtered by the first filtering structure 1034 can flow to the dust outlet. The dirt filtered by the second filtering structure 1035 can also flow towards the dust outlet. Thus, the dirt filtered by each filtering structure can be discharged from the dust outlet, so that the dirt discharge is more thorough. Moreover, the first dust falling channel and the second dust falling channel can be simultaneously sealed by the dust cup cover 1033. The number of dust cup covers 1033 is smaller, and the structure is simpler. Therefore, when discharging dirt, only one dust cup cover 1033 needs to be opened to discharge all the dirt, and the dirt discharge effect is better.

[0072] Preferably, as shown in FIGS. 2 and 3, the first filtering structure 1034 and the second filtering structure 1035 are coaxially arranged with the dust cup cavity 1031. After the dust collector device 100 is placed on the dust collecting station 200, the center of gravity is better matched with the accommodating cavity 11, so that the dust collector device 100 is placed more stably. Moreover, the axial direction of the first filtering structure 1034 and the axial direction of the second filtering structure 1035 are perpendicular to the axial direction of the air inlet end of the suction device 104. The suction device 104 can be provided with an axial flow fan. The rotation shaft of the impeller of the axial flow fan is arranged in the horizontal direction. The axial direction of the dust cup cavity 1031 is arranged in the up-down direction. The suction device 104 is arranged above the dust cup cavity 1031. The center of gravity of the entire dust collector device 100 is more centered in the horizontal direction. Thus, when the dust collector device 100 is placed on the dust collecting station 200 in the up-down direction, the dust collector device 100 is more stable on the dust collecting station 200 and is not easy to be tilted.

[0073] Further preferably, as shown in FIG. 4, the dust cup assembly 103, the dirt discharge port 1032 and the dirt inlet port 21 are coaxially arranged. When the air duct switching structure 102 is in the first working state, the suction device 104 on the dust collector device 100 is connected to the dirt storage cavity 2. The airflow can better flow from the dust cup assembly 103 to the direction of the dirt discharge port 1032 and the dirt inlet port 21, so as to bring the dirt into the dirt storage cavity 2. The airflow is subjected to less air resistance, so that the dirt discharge efficiency is higher.

[0074] The air duct switching structure 102 is mainly used for switching the working state of the dust collector device 100, so that the suction device 104 can be better communicated with the dust cup assembly 103 or better communicated with the dust collecting station 200. Specifically, as shown in FIG. 3, a first channel and a second channel are formed on the device body 101; the first channel is communicated with the suction device 104 and the dust cup assembly 103, and the second channel is adapted to be communicated with the suction device 104 and the dust collecting station 200; 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 for blocking and communicating the first channel, and the second shielding part 1022 is used for blocking and communicating the second channel; 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 communicating the second channel, and a second working state of communicating the first channel and blocking the second channel.
