[0004] The present disclosure relates to the technical field of dust collector system, in particular to a dust collector system. BACKGROUND

[0005] At present, a dust collector system usually comprises a dust collector device (such as a dust collector) and a dust collection station. The dust collector can be subjected to dust extraction treatment by the dust collection station, without the need for the user to manually pour dust. The dust collection station is provided with a docking interface, a dust bag for collecting dust, and a dust collection station motor for providing a dust extraction negative pressure. When the dust collector is docked with the docking interface of the dust collection station, a negative pressure is generated by the action of the dust collection station motor, so as to extract the dust in the dust cup of the dust collector. In this way, the user does not need to pour dust after each cleaning, and the user can pour dust once a month or even longer. However, the special dust collection station motor provided on the dust collection station leads to a relatively complex structure of the entire system, high cost, and is not conducive to installation and maintenance.

[0078] The present disclosure provides a dust collector system, which includes a dust collecting station 100 and a dust collector device 200. The specific form of the dust collector device 200 is not limited, and the use direction of the dust collector device 200 may differ in actual application. However, for the convenience of understanding, in the following embodiments, the handheld dust collector device 200 shown in FIGS. 1 to 19 is taken as an example for description, and at this time, the dust collector device 200 is in a stationary state, having a substantially vertical up-down direction and a horizontal direction.

[0079] Therefore, the dust collector device 200 generally includes a casing, which can be divided into multiple components according to its functions, and can be but is not limited to an air inlet part 211 and a dust storage part 212. According to actual needs, it can also include an air outlet part 213.

[0080] The air inlet part 211 is a structural component through which external air can enter the casing. The air inlet part 211 generally forms an air inlet duct, and the upstream of the air inlet duct can directly constitute the air inlet of the entire machine. According to actual needs, the air inlet part 211 can also be connected with some accessory brush heads for cleaning in different scenes, such as pet brush heads, gap brush heads, acarid removal brush heads, and the like.

[0081] The dust storage part 212 has a dust storage cavity 212a formed inside. The downstream of the air inlet duct can be connected with the upstream of the dust storage cavity 212a. The dust storage part 212 can be arranged to extend in a columnar shape along the up-down direction, and at this time, the air inlet part 211 can be arranged on one side of the dust storage part 212 in the horizontal direction, and the air inlet part 211 and the air inlet duct formed inside can extend and be arranged along the horizontal direction.

[0082] The inside of the air outlet part 213 is generally formed with an air outlet air duct 213a, the upstream of which is connected in communication with the downstream of the dust storage cavity 212a, and the downstream of the air outlet part 213 can generally directly constitute the air outlet of the whole machine, so that after the dust in the gas carrying the dust is intercepted in the dust storage cavity 212a, the air outlet part 213 can discharge the relatively clean gas to the outside through the air outlet.

[0083] The holding part is also the part that can be held by the user to drive the whole machine to move, and its specific structure is not limited, which can be but is not limited to a rod shape or a ring shape.

[0084] As shown in FIGS. 1-3, in order to make the structure of the whole machine compact, the dust storage part 212 and the air outlet part 213 can both be arranged to extend in a column shape along the up-down direction, and the air outlet part 213 is arranged above the dust storage part 212. The air inlet part 211 is arranged on one side of the dust storage part 212 along the horizontal direction, and the holding part is arranged on the other side of the dust storage part 212 along the horizontal direction.

[0085] In view of the above, the dust collector device 200 can be used at least for dust collection. In order to achieve the purpose that the gas enters the air inlet air duct from the air inlet, passes through the dust storage part 212 and the air outlet part 213, and is finally discharged to the outside by the air outlet, in a specific application, the dust collector device 200 further comprises a gas driving device 220. The gas driving device 220 refers to any device that can achieve the purpose of driving the directional flow of gas, which can be composed of a single device (such as a fan) alone, or composed of at least two single devices (such as a fan and a wind guide structure) in combination. The gas driving device 220 can include a fan, which can be but is not limited to an axial fan, a cross-flow fan, a centrifugal fan, etc. The gas driving device 220 generally has a suction side 221 and a discharge side 222 in a normal operating state. When started, the suction side 221 of the gas driving device 220 forms a negative pressure, which can suck the external airflow into the inside of the gas driving device 220; the discharge side 222 forms a positive pressure, which can discharge the airflow in the inside of the gas driving device 220 to the outside.

[0086] In actual application, the exhaust side 222 of the driving gas device 220 can be connected to the air inlet to blow gas into the air inlet duct, so that the driving gas enters the air inlet duct, passes through the dust storage cavity 212a and the air outlet duct 213a, and is finally discharged outward from the air outlet. However, in order to reduce the adverse effect of the driving gas device 220 on the air flow of the air inlet part 211, in the embodiments shown in FIGS. 1-19, the suction side 221 of the driving gas device 220 is connected to the downstream of the air outlet duct 213a, and the exhaust side 222 of the driving gas device 220 constitutes the air outlet of the whole machine. In addition, in order to achieve the purpose of trapping the dirt carried by the external gas connected to the air inlet part 211 in the dust storage cavity 212a, the dust collector device 200 can further include at least one filter, which is arranged at least in the dust storage cavity 212a and can also be arranged in the air outlet duct 213a. The number and specific type of the filter are not limited, for example, as shown in FIG. 3, the filter can be but is not limited to one or more of a first filter 241, a second filter 242, and a pre-filter 243. The first filter 241 can be a porous filter arranged in a cylindrical shape, the second filter 242 can be a multi-cone filter, and the first filter 241 and the second filter 242 are arranged at the upstream section of the dust storage cavity 212a. The pre-filter 243 is arranged in a cylindrical shape at the downstream section of the dust storage cavity 212a, for example, at the communication between the dust storage cavity 212a and the air outlet duct 213a, or directly at the air outlet duct 213a. Generally, the structure composed of the dust storage part 212 and at least one filter, i.e., the dust cup assembly.

[0087] In addition, in order to realize the orderly operation of each component in the dust collector system, the dust collector system can further comprise a power supply device 800 and a control device. The power supply device 800 can include but is not limited to a disposable charging and discharging power supply device, such as a disposable battery; or the power supply device 800 can also include a rechargeable power supply device, such as a storage battery that can be electrically connected to the mains. The power supply device 800 can be arranged in the housing, for example, on the side of the air driving device 220 opposite to the air outlet part 213 / dust storage part 212. The control device can be electrically connected with the power supply device 800 and the air driving device 220, so as to control the charging and discharging of the power supply device 800, and control the air driving device 220 to start operation, stop operation, and adjust the preset operation power, according to the actual needs, such as according to the preset program, or in response to the trigger instruction of the user. The control device can be built-in on the dust collector device 200, or can be externally arranged at the dust collection station 100 or other positions according to actual needs, and can realize communication and exchange with the air driving device 220 on the dust collector device 200 through wireless connection. As shown in FIG. 3, the power supply device 800 can be arranged on the side of the air driving device 220 away from the air inlet part 211, and opposite to the air inlet part 211.

[0088] In addition, the dust collector device 200 and / or the dust collection station 100 can further be provided with a display module and / or an input device. The display module includes a display panel which can display numbers or graphics according to actual needs. The input device can be but not limited to physical buttons or virtual buttons, sound recognition module, posture recognition module, etc., which can be manually entered by the user to input related trigger instructions.

[0089] Of course, according to actual needs, the dust collector device 200 and / or the dust collection station 100 can also be provided with one or more sensor devices. The sensor device is electrically connected with the control device, so that the control device can intelligently control the operation of the corresponding functional components according to the sensing data of the sensor device. The sensor device can be arranged at the docking position of the dust collector device 200 and the dust collection station 100, and is triggered and forms a sensing signal when the dust collector device 200 and the dust collection station 100 are docked.

[0090] Further, in view of any one or more embodiments of the dust collector device 200 described above, the dust collection station 100 is generally a product used in conjunction with the dust collector device 200. The dust collector device 200 has a first working state of operating independently from the dust collection station 100, and a second working state after being docked with the dust collection station 100. When in the second working state, the dust collection station 100 can perform a plurality of preset operations on the dust collector device 200 under the driving of a preset program, or in response to a trigger instruction of the user. The preset operations can be but not limited to charging, cleaning, dust extraction, etc.

[0091] In view of the above one or more embodiments of the dust collector system, in order to overcome the drawbacks of the prior art that the motor of the dust collection station 100 needs to be specially arranged, resulting in complex structure of the whole system and high maintenance cost, the following will be specifically combined with the drawings to provide several specific embodiments for description.

[0092] Specific embodiment 1:

[0093] Referring to FIGS. 1-19, the present disclosure provides a dust collector system, which can be but is not limited to the dust collector system in one or more of the above embodiments.

[0094] Specifically, the dust collector system provided by the present disclosure includes a dust collection station 100 and a dust collector device 200, the dust collector device 200 includes a gas driving device 220, the dust collector system has a first air duct and a second air duct, and the gas driving device 220 can selectively act on the first air duct or the second air duct; wherein when acting on the first air duct, the dust collector device 200 independently operates under the gas flow of the first air duct; when acting on the second air duct, the dust collector device 200 is docked with the dust collection station 100, and at least the dust collection station 100 independently operates under the gas flow of the second air duct.

[0095] In the technical solution provided by the present disclosure, the same gas driving device 220 can support the independent operation of the dust collector device 200 when acting on the first air duct, and at least support the independent operation of the dust collection station 100 when acting on the second air duct. Compared with the prior art of arranging a fan on the dust collection station 100 and the dust collector device 200 respectively, the present disclosure can obviously reduce the number of gas driving devices 220, thereby helping to at least simplify the structure of the dust collection station 100, and the single gas driving device 220 is easier to maintain, which ultimately helps to improve the use quality of the whole machine.

[0096] In the present design, the gas driving device 220 has an air suction side and an air exhaust side as described above, so that the gas driving device 220 can form positive pressure or negative pressure in the first air duct and / or the second air duct when acting on the first air duct and / or the second air duct. The following will be specifically described in combination with specific embodiments.

[0097] In addition, since the dust collector device 200 generally needs a gas driving device 220 when independently operating, the gas driving device 220 can be pre-integrated in the housing of the dust collector device 200, which helps to compact the structure. Of course, according to actual needs, the gas driving device 220 can also be external to the dust collector device 200.

[0098] It should be noted that the dust collector device 200 operates independently under the gas flow of the first air duct, which means that the dust collector device 200 operates independently compared to the dust collecting station 100, that is, the dust collector device 200 does not depend on the dust collecting station 100 at present, but is not limited to only the operation of the dust collector device 200 itself. Therefore, in the present design, according to the needs of the independent operation of the dust collector device 200, the first air duct can be independently arranged on the dust collector device 200, so that when the air driving device 220 acts on the first air duct, the dust collector device 200 operates independently; or the first air duct can also be commonly arranged between the dust collector device 200 and other external devices other than the dust collecting station 100, so that when the air driving device 220 acts on the first air duct, the dust collector device 200 and other external devices can selectively operate together.

[0099] When the dust collector device 200 independently constitutes the first air duct, specifically, when the dust collector device 200 includes the air inlet part 211 and the dust storage part 212 as described above, the first air duct can be commonly constituted by the air inlet duct and the dust storage cavity 212a; when the dust collector device 200 includes the air inlet part 211, the dust storage part 212 and the dust outlet part as described above, the first air duct can be commonly constituted by the air inlet duct, the dust storage cavity 212a and the air outlet duct 213a. The above can realize the dust collection operation under the negative pressure action of the air driving device 220. The dust collection operation means that the dirt in the external environment, for example, at the cleaning area, is brought into the dust storage cavity 212a through the air inlet duct under the action of the gas, and the dirt is intercepted in the dust storage cavity 212a.

[0100] When the dust collector device 200 and other external devices commonly constitute the first air duct, taking the case that the first air duct in the air duct section of the dust collector device 200 at least includes the dust storage cavity 212a as an example, the other external devices can be devices for processing the dust storage cavity 212a, for example, can be a high-temperature steam generating device, which can input high-temperature steam into the dust storage cavity 212a under the negative pressure action of the air driving device 220, to realize high-temperature steam cleaning of the dust storage cavity 212a; can also be a disinfection device, which can input disinfection gas into the dust storage cavity 212a under the negative pressure action of the air driving device 220, to realize sterilization and disinfection of the dust storage cavity 212a; can also be a high-temperature gas generating device, which can input high-temperature hot gas into the dust storage cavity 212a under the negative pressure action of the air driving device 220, to realize high-temperature drying of the dust storage cavity 212a, etc.

[0101] Similarly, when the air driving device 220 acts on the second air duct:

[0102] If the dust collector 200 is not connected with the dust collecting station 100 at this time, according to the requirement of the independent operation of the dust collecting station 100, the second air duct can be independently arranged on the dust collecting station 100, so that the dust collecting station 100 independently operates by itself when the air driving device 220 acts on the second air duct; or the second air duct can also be commonly arranged between the dust collecting station 100 and other external devices except the dust collector 200, so that the dust collecting station 100 and other external devices can selectively operate together when the air driving device 220 acts on the second air duct.

[0103] If the dust collector 200 is connected with the dust collecting station 100 at this time, according to the requirement of the independent operation of the dust collecting station 100, similarly, the second air duct can be independently arranged on the dust collecting station 100, so that the dust collecting station 100 independently operates by itself when the air driving device 220 acts on the second air duct; or the second air duct can be commonly arranged between the dust collecting station 100 and the dust collector 200, so that the dust collecting station 100 and the dust collector 200 can selectively operate together when the air driving device 220 acts on the second air duct; or the second air duct can also be commonly arranged between the dust collecting station 100 and other external devices except the dust collector 200, so that the dust collecting station 100 and other external devices can selectively operate together when the air driving device 220 acts on the second air duct.

[0104] When the dust collecting station 100 independently constitutes the second air duct, specifically, the dust collecting station 100 can be provided with a dust collecting cavity, i.e. a cavity for collecting dirt. The second air duct can be constituted by the dust collecting cavity. When the air driving device 220 acts on the second air duct, a negative pressure can be generated in the dust collecting cavity, for example, to compress the dirt; or a positive pressure can be formed in the dust collecting cavity to discharge the dirt in the dust collecting cavity outward, so that the dust collecting station 100 does not need to be dumped or the like. Of course, other cavities can also be arranged in the dust collecting station 100, and the other cavities constitute the second air duct. The other cavities can be, but are not limited to, for example, heat dissipation flow channels of high-power electric control devices, and when the air driving device 220 acts on the second air duct, the high-power electric control devices can be cooled by driving the gas flow.

[0105] When the dust collecting station 100 and the dust collector 200 jointly define the second air duct:

[0106] Firstly, it needs to be explained that when the air driving device 220 acts on the second air duct, and after the dust cleaner device 200 is docked with the dust collecting station 100, the dust cleaner device 200 and the dust collecting station 100 can be cooperatively operated under the gas flow of the second air duct, but it is not limited that the dust cleaner device 200 and the dust collecting station 100 must start the cooperative operation mode. In actual application, the cooperative operation of the dust cleaner device 200 and the dust collecting station 100 can be selectively triggered, or the dust collecting station 100 can be independently operated, by means such as manual triggering by the user, automatic control by the program, etc.

[0107] Next, the second air duct formed by the dust collecting station 100 and the dust cleaner device 200 can be used to perform various suitable operations by using the flowing gas:

[0108] One of them is to directly use the gas flow to transfer the target object:

[0109] For example, in an embodiment, the second air duct is connected between the dust cleaner device 200 and the dust collecting station 100, and when the air driving device 220 acts on the second air duct, the dust cleaner device 200 and the dust collecting station 100 perform target object transfer under the gas flow of the second air duct. At this time, the target object is not limited and can be, but is not limited to, dirt, liquid, etc. The transfer path is not limited and can be to transfer the target object in the external environment to the dust cleaner device 200 and / or the dust collecting station 100 through the second air duct, or can be to transfer the target object in the dust cleaner device 200 to the dust collecting station 100 through the second air duct, or can also be to transfer the target object in the dust collecting station 100 to the dust cleaner device 200 through the second air duct.

[0110] More specifically, in an embodiment, the air driving device 220 has a suction side and an exhaust side; when acting on the second air duct at the suction side, a negative pressure is formed in the second air duct, generating a suction air flow, which drives the dirt to transfer from the dust cleaner device 200 to the dust collecting station 100, and performs a dust suction operation.

[0111] The dirt can be dirt generated or stored at any position of the dust cleaner device 200, such as dirt remaining on at least one filter in the dust cleaner device 200, or can be dirt trapped in the dust storage cavity 212a of the dust cleaner device 200 after the dust suction operation is performed. The dirt can be transferred to any position in the dust collecting station 100, such as a dust collecting cavity provided in the dust collecting station 100 to store the dirt in the dust collecting cavity, or a dirt collecting tank provided at an opening of the dust collecting station 100 to directly collect liquid dirt or solid-liquid mixed dirt in the dirt collecting tank for easy discharge.

[0112] More specifically, in an embodiment, the dust collector device 200 is provided with a dust storage cavity 212a, which constitutes at least part of the first air duct; the dust collection station 100 is provided with a dust collection cavity, and after the dust collector device 200 is docked with the dust collection station 100, the dust collection cavity and the dust storage cavity 212a are in communication, and together constitute at least part of the second air duct, so that when the suction side acts on the second air duct, the dirt in the dust storage cavity 212a is transferred to the dust collection station 100. In this way, when the gas driving device 220 acts on the first air duct, the dust collector device 200 can independently operate the dust collection operation, and the dust storage cavity 212a will trap and store dirt; when the gas driving device 220 acts on the second air duct and the dust collector device 200 is docked with the dust collection station 100, the dust collection cavity will collect the dirt stored in the dust storage cavity 212a, and operate the dust extraction operation. Since the dust collection station 100 has a larger space reserved for the dust collection cavity, and the dust collection station 100 has relatively less restrictions on mass, size, and other structural designs compared to the dust collector device 200, the dust collection cavity can generally store dirt brought by at least two dust extraction operations, facilitating subsequent centralized dumping or external disposal, reducing the cleaning frequency of the dust collector system, and helping to improve user experience.

[0113] Secondly, the force generated by the gas flow is utilized:

[0114] For example, in an embodiment, after the gas driving device 220 acts on the second air duct and the dust collector device 200 is docked with the dust collection station 100, the gas formed at the second air duct triggers the preset function of the dust collection station 100 to operate, so as to realize the independent operation of the dust collection station 100. The preset function is not limited, for example, the above-mentioned dust extraction function, but also cleaning function of the dust collector device 200, charging function of the dust collector device 200, etc.

[0115] There are many schemes for triggering the preset function of the dust collection station 100 by the gas formed at the second air duct: further, in an embodiment, the dust collector system is provided with a trigger 234, which is used to trigger the sensing signal associated with the preset function when pressed; the trigger 234 is arranged on the flow path of the gas at the second air duct, so that when the gas driving device 220 acts on the second air duct, the gas formed at the second air duct presses the trigger 234. The trigger 234 can be directly arranged in the second air duct, or arranged outside the second air duct but on the flow path of the gas at the second air duct, and the force brought by the gas flow can press the trigger 234 to trigger the sensing signal of the trigger 234. Or in an embodiment, the dust collector system is provided with a sensor, which is also arranged on the flow path of the gas at the second air duct, and can sense one or more of the parameters such as wind power, wind speed, wind direction, etc. When the gas flows and meets the preset condition, the sensing signal is triggered, and the preset function of the dust collection station 100 is triggered to operate.

[0116] When the dust collecting station 100 and other external devices jointly define the second air duct:

[0117] Similarly to the first air duct, for example, the air duct segment of the second air duct in the dust collecting station 100 at least includes the dust collecting cavity, the other external device can be a device for processing the dust collecting cavity, for example, it can be a high-temperature steam generating device, which can access high-temperature steam into the dust collecting cavity under the negative pressure action of the air driving device 220, to realize high-temperature steam cleaning of the dust collecting cavity; it can also be a disinfection device, which can access disinfection gas into the dust collecting cavity under the negative pressure action of the air driving device 220, to realize sterilization and disinfection of the dust collecting cavity; it can also be a high-temperature gas generating device, which can access high-temperature hot gas into the dust collecting cavity under the negative pressure action of the air driving device 220, to realize high-temperature drying of the dust collecting cavity, etc.

[0118] It should be noted that in the above and below embodiments, the docking of the dust collector device 200 and the dust collecting station 100 means that the dust collector device 200 and the dust collecting station 100 start the docking action, which can be at the same time as the dust collector device 200 and the dust collecting station 100 start the docking action, or at the same time as the two complete the docking action, or within a certain time after the two complete the docking action, etc.

[0119] The timing of the air driving device 220 acting on the second air duct, and the docking timing of the dust collector device 200 and the dust collecting station 100, do not have strict restrictions on the sequence. For example, when the second air duct is jointly constituted by the dust collecting station 100 and the dust collector device 200 as described above, the docking of the dust collector device 200 and the dust collecting station 100 can be performed first, and then the air driving device 220 is triggered to act on the second air duct at the same time or after a delay.

[0120] The triggering mode of the air driving device 220 acting in the second air duct is also not limited, which can be directly triggered by the docking action of the dust collector device 200 and the dust collecting station 100, or manually triggered by the user, or automatically triggered by the preset program control (independent execution of the control device, or cooperation of the control device and the sensor) and the like.

[0121] Based on any of the above embodiments, in a further scheme, the first air duct can be adjusted to be on or off, that is, the first air duct itself has a conduction state and a cutoff state. When the first air duct is in the cutoff state, even if the air driving device 220 acts in the first air duct, no path can be formed, and the dust collector device 200 is not currently started to run the corresponding function. The on-off adjustment of the first air duct can be manually switched by the user, automatically controlled by the preset program, or cooperatively controlled by the sensor and the control device.

[0122] And / or in a further aspect, the communication connection between the first air duct and the air driving device 220 is adjustable, i.e. the first air duct and the air driving device 220 can be connected or the first air duct and the air driving device 220 can be disconnected.

[0123] Similarly, in a further aspect, the second air duct is adjustable, i.e. the second air duct itself has a connected state and a disconnected state. When the second air duct is in the disconnected state, even if the air driving device 220 acts in the second air duct, no passage can be formed, and the dust collection station 100 is not currently activated to operate the corresponding function. The on-off adjustment of the second air duct can be manually switched by the user, automatically controlled by the preset program, cooperatively controlled by the sensor and the control device, etc.

[0124] And / or in a further aspect, the communication connection between the second air duct and the air driving device 220 is adjustable, i.e. the second air duct and the air driving device 220 can be connected or the second air duct and the air driving device 220 can be disconnected.

[0125] For the on-off setting of the second air duct, in a further aspect, the on-off switching of the second air duct can be achieved by the docking action of the dust collector device 200 and the dust collection station 100. For example, after the dust collector device 200 and the dust collection station 100 are docked, the second air duct is automatically connected. At this time, similarly, the docking action of the dust collector device 200 and the dust collection station 100 can be directly mechanically linked, for example, a pressing piece is arranged at the docking position of the dust collector device 200 and the dust collection station 100, and the pressing piece is pressed and triggered by the force when the dust collector device 200 and the dust collection station 100 are docked. Or it can be electrically linked by the docking action of the dust collector device 200 and the dust collection station 100, for example, a sensor is arranged at the docking position of the dust collector device 200 and the dust collection station 100, and the sensor triggers an induction signal when the dust collector device 200 and the dust collection station 100 are docked. The sensor can be, but is not limited to, a force sensor, a photoelectric sensor, etc.; for example, an electrical connection terminal and an electrical docking terminal are respectively arranged at the docking position of the dust collector device 200 and the dust collection station 100, and the electrical connection terminal and the electrical docking terminal are electrically connected to form a passage when the dust collector device 200 and the dust collection station 100 are docked, triggering an electrical signal. And so on.

[0126] In the above-mentioned aspect of electrical linkage, the dust collector system further comprises a switching device 230, which is electrically connected with the above-mentioned sensor, electrical connection terminal, electrical docking terminal and / or control device connected therewith, so that when receiving the induction signal or electrical signal, the switching device 230 connects the second air duct.

[0127] For the on-off setting between the second air duct and the air driving device 220, it can be realized by the docking action of the dust collector device 200 and the dust collecting station 100, and will not be repeated here.

[0128] When the dust collector device 200 and the dust collecting station 100 are docked and the second air duct is connected, the first air duct can also be in a connected state at this time; or in order to reduce the interference to the second air duct, and make the effect of the air driving device 220 more concentrated at the second air duct, the first air duct can be in an isolated state at this time, or the first air duct and the air driving device 220 are in an isolated state.

[0129] As described above, the first air duct and the second air duct can be two independent air duct structures that are completely independent and not connected to each other. Alternatively, the first air duct and the second air duct share at least a partial air duct section (for example, the dust storage cavity 212a is shared as described above, or other), based on which, in an embodiment, after the dust collector device 200 is docked with the dust collecting station 100, the first air duct and the second air duct share a partial air duct section (for example, the shared air duct section 215a in the following embodiment), and are connected to the air driving device 220, the remaining air duct section of the first air duct (for example, the remaining dust suction section 215b described below) and / or the remaining air duct section of the second air duct (for example, the remaining dust extraction section 111a described below) can be adjusted to be on or off. In this way, it is not necessary to repeatedly operate the on-off nature between the air driving device 220 and the first air duct, and / or between the air driving device 220 and the second air duct, and to maintain the air duct section shared by the air driving device 220, the first air duct and the second air duct to be connected, only the on-off of the remaining air duct section of the first air duct and the second air duct needs to be operated, and the overall structure is more compact.

[0130] In addition, in an embodiment, the air driving device 220 can be movably arranged to be movable to be connected to the first air duct and to be connected to the second air duct. In this way, by the movement adjustment of the air driving device 220, the air suction side of the air driving device 220 can be directed towards or away from the first air duct and / or the second air duct, when the air suction side is directed towards the first air duct, that is, acts on the first air duct, the air suction side and the first air duct are connected; on the contrary, when the air suction side is directed towards the second air duct, that is, acts on the second air duct, the air suction side and the second air duct are connected.

[0131] In the following specific embodiments, the switching device 230 will be described in detail with reference to specific embodiments.

[0132] Specific embodiment 2:

[0133] Please refer to FIGS. 1-19, the present disclosure provides a dust collector system, which can be but is not limited to the dust collector system described in one or more of the above embodiments.

[0134] The dust collector system comprises a dust collecting station 100 and a dust collector device 200, the dust collecting station 100 is provided with a dust collecting cavity; the dust collector device 200 comprises an air inlet part 211, a dust storage part 212, a pre-filter and a gas driving device 220, the dust storage part 212 is provided with a dust storage cavity 212a; the dust collector system has a first air duct and a second air duct, the first air duct is sequentially communicated with the air inlet part 211, the dust storage part 212, the pre-filter and the gas driving device 220, the second air duct is communicated with the dust storage cavity 212a, the dust collecting cavity and the gas driving device 220; the gas driving device 220 can selectively act on the first air duct and / or the second air duct, wherein when the gas driving device 220 acts on the first air duct, the gas flow is driven to flow from the air inlet part 211 into the dust storage part 212, then flow through the pre-filter and finally flow to the gas driving device 220; when the gas driving device 220 acts on the second air duct, the gas flow is driven to flow from the dust storage cavity 212a into the dust collecting cavity and finally flow to the gas driving device 220.

[0135] In the design, when the gas driving device 220 acts on the first air duct, the external gas flow enters the dust storage part 212 through the air inlet part 211, then passes through the pre-filter and finally flows to the gas driving device 220, and the dust collection operation is performed. Wherein, when the external gas flow enters the dust storage part 212, it is filtered by the first filter 241 and the second filter 242 arranged at the dust storage cavity 212a, for example, the dirt is retained in the dust storage cavity 212a, and the relatively clean gas passes through the pre-filter for further filtering and finally returns to the gas driving device 220.

[0136] Wherein, the pre-filter can be but not limited to the pre-filter 243. The pre-filter is arranged in one or at least two between the dust storage cavity 212a and the gas driving device 220. Wherein, when the pre-filter is arranged in multiple, at least one of each pre-filter can be arranged as the pre-filter 243.

[0137] When the gas driving device 220 acts on the second air duct, the gas flow enters the dust collecting cavity from the dust storage cavity 212a, carries the dirt in the dust storage cavity 212a into the dust collecting cavity, and performs the dust extraction operation. Finally, the gas still flows to the gas driving device 220.

[0138] No matter acting on the first air duct or the second air duct, the gas flow finally returns to the gas driving device 220, which makes the structure of the gas driving device 220, the first air duct and the second air duct more compact, and makes the structure of the whole machine more simplified and the layout more reasonable.

[0139] Similarly to the first air duct, in an embodiment, the dust collector system further comprises a second filter, which is arranged in the second air duct and between the dust collection chamber and the air driving device 220. The arrangement of the second filter can filter the gas before it returns to the air driving device 220 from the dust collection chamber, so as to avoid impurities from entering the air driving device 220 and causing the air driving device 220 to be blocked and lose function.

[0140] In view of the above, the air duct section of the first air duct between the dust storage chamber 212a and the air driving device 220 is the air outlet duct 213a, and the air duct section of the first air duct between the pre-filter and the air driving device 220 is the connecting air duct 214. Taking the pre-filter 243 as an example, when the pre-filter 243 is arranged close to the downstream of the dust storage chamber 212a, the connecting air duct 214 is substantially the air outlet duct 213a. When the pre-filter 243 is spaced apart from the downstream of the dust storage chamber 212a by a distance, the pre-filter 243 divides the air outlet duct 213a into two air duct sections, and the air duct section between the pre-filter 243 and the air driving device 220 constitutes the connecting air duct 214. At least part of the connecting air duct 214 is arranged around the periphery of the pre-filter 243, and the pre-filter 243 is wrapped in the ring, which is helpful to the compact structure of the whole machine.

[0141] The air suction duct 110 and the connecting air duct 214 can be in communication, and the air duct outlet 215c is formed at the communication position of the two air ducts. The air duct outlet 215c is close to the pre-filter 243, which is helpful to the compact structure of the whole machine.

[0142] Further, the connecting air duct 214 can be arranged to be in a snail shape around the periphery of the pre-filter 243. The snail shape can refer to a single-ring annular shape, or can refer to a multi-ring annular shape. The single-ring annular shape can be a whole-ring annular shape, or can be a partial-ring annular shape formed by an arc segment.

[0143] The air duct section of the second air duct between the dust collection chamber and the air driving device 220 is the air suction duct 110; the suction side of the air driving device 220 can selectively act on the connecting air duct 214 or the air suction duct 110, and the air suction duct 110 and the connecting air duct 214 are closer, which is more conducive to the compact and reasonable layout of the air driving device 220.

[0144] In addition, in an embodiment, the suction side of the air driving device 220 is in communication with the connecting air duct 214 and the air suction duct 110, respectively; and the dust collector system further comprises a switching device 230, which can adjust the first air duct and the second air duct in an on-off manner, respectively.

[0145] The switching device 230 has a first switching state in which the second air channel is open. It can be understood that in the first switching state, the air driving device 220 is open to the local area in the dust collecting station 100, but at this time the air driving device 220 can be open to or isolated from the local area in the dust cleaner 200.

[0146] Specifically, when the dust collecting cavity is provided in the dust collecting station 100 and the dust storage cavity 212a is provided in the dust cleaner 200, the switching device 230 in the first switching state can be set to open the air driving device 220 to the dust collecting cavity and isolate the air driving device 220 from the dust storage cavity 212a, thereby realizing the dust extraction operation as described above.

[0147] Similarly, the switching device 230 also has a second switching state in which the first air channel is open. It can be understood that in the second switching state, the air driving device 220 is open to the local area in the dust cleaner 200, but at this time the air driving device 220 can be open to or isolated from the local area in the dust collecting station 100.

[0148] Specifically, when the dust collecting cavity is provided in the dust collecting station 100 and the dust storage cavity 212a is provided in the dust cleaner 200, the switching device 230 in the second switching state can be set to open the air driving device 220 to the dust storage cavity 212a and isolate the air driving device 220 from the dust collecting cavity, thereby realizing the dust collection operation as described above.

[0149] There are many schemes for the switching device 230 to achieve the above purposes:

[0150] In an application, the switching device 230 can be a component that directly acts on the air driving device 220:

[0151] For example, when the air driving device 220 is a mechanism that can interchange the suction side and the exhaust side of itself, the switching device 230 is set as a component that can control the air driving device 220 to perform the interchanging operation. At this time, when the switching device 230 adjusts the suction side of the air driving device 220 to be open to the first air channel, the switching device 230 is in the second switching state; conversely, when the switching device 230 adjusts the suction side of the air driving device 220 to be open to the second air channel, the switching device 230 is in the first switching state.

[0152] Alternatively, for example, the air driving device 220 is a mechanism that can be movably arranged relative to the first air channel and the second air channel, and the switching device 230 is set as a component that can drive the air driving device 220 to perform translational movement or rotational movement. At this time, the switching device 230 can be in the second switching state when driving the suction side of the air driving device 220 to be open to the first air channel, and in the first switching state when driving the suction side of the air driving device 220 to be open to the second air channel.

[0153] In another application, the switching device 230 can also be an opening and closing structure acting on the air suction duct 110 and / or acting on the air outlet duct 213a (specifically, the connecting duct 214). The opening and closing structure is movably arranged to be able to move between the first switching state and the second switching state.

[0154] Correspondingly, the opening and closing structure can be used to open the air outlet duct 213a and close the air suction duct 110 (i.e., the switching device 230 has the second switching state alone); can be used to open the air suction duct 110 and close the air outlet duct 213a (i.e., the switching device 230 has the first switching state alone); or can be switched between the first switching state and the second switching state (i.e., the switching device 230 has both the first switching state and the second switching state).

[0155] Specifically, taking the opening and closing structure as an example, which can be switched between the first switching state and the second switching state:

[0156] In one application, the opening and closing structure can be arranged to include an opening and closing member. At this time, the air suction duct 110 and the air outlet duct 213a are arranged on the moving path of the opening and closing member, so that the opening and closing member can close the air suction duct 110 and open the air outlet duct 213a when moving close to the air suction duct 110 and moving away from the air outlet duct 213a (at this time, the switching device 230 is in the second switching state), and can close the air outlet duct 213a and open the air suction duct 110 when moving close to the air outlet duct 213a and moving away from the air suction duct 110 (at this time, the switching device 230 is in the first switching state). In this way, it is helpful to simplify the opening and closing structure, but it has certain restrictions on the structural design of the air outlet duct 213a and the air suction duct 110.

[0157] Or in another application, the opening and closing structure can be provided to include at least two opening and closing members, which are respectively the first opening and closing member 231 and the second opening and closing member 232. Wherein the first opening and closing member 231 is movably arranged between the air driving device 220 and the dust storage cavity 212a (i.e. movably arranged at the air outlet air duct 213a), so as to have a first opening position and a first closing position; the second opening and closing member 232 is movably arranged between the air driving device 220 and the dust collection station 100 (i.e. movably arranged at the air inlet air duct 110), so as to have a second opening position and a second closing position; wherein when the first opening and closing member 231 is moved to the first closing position and the second opening and closing member 232 is moved to the second opening position, the first opening and closing member 231 blocks the air outlet air duct 213a and the second opening and closing member 232 opens the air inlet air duct 110, and the switching device 230 is in the first switching state; when the first opening and closing member 231 is moved to the first opening position and the second opening and closing member 232 is moved to the second closing position, the first opening and closing member 231 opens the air outlet air duct 213a and the second opening and closing member 232 blocks the air inlet air duct 110, and the switching device 230 is in the second switching state. In this way, it is helpful to reduce the restriction on the structural design of the air outlet air duct 213a and the air inlet air duct 110, so that the structures of the first opening and closing member 231 and the second opening and closing member 232 remain relatively independent.

[0158] Please refer to FIGS. 1-8, and take the first opening and closing member 231 and the second opening and closing member 232 in the above example:

[0159] It can be understood that the first opening and closing member 231 and the second opening and closing member 232 are independently formed with their own movement modes, for example, the first opening and closing member 231 can be selectively provided to perform translational movement and / or rotational movement, and the second opening and closing member 232 can also be selectively provided to perform translational movement and / or rotational movement.

[0160] At this time, the movements of the first opening and closing member 231 and the second opening and closing member 232 can be independent of each other, that is, the movement time, movement path, movement direction, driving mode, etc. of the first opening and closing member 231 are not affected by the second opening and closing member 232; vice versa, the movement time, movement path, driving mode, etc. of the second opening and closing member 232 are not affected by the first opening and closing member 231. The first opening and closing member 231 and the second opening and closing member 232 can be respectively configured with a driving source, of course, the driving source can also come from manual operation of the user, and can also come from different mechanical mechanism driving respectively.

[0161] Or the activities of both the first opening and closing member 231 and the second opening and closing member 232 can be linked, that is, the first opening and closing member 231 and the second opening and closing member 232 have mutual influence in at least one of the activity time, the activity path, the activity direction, the driving mode, etc. The first opening and closing member 231 and the second opening and closing member 232 can be configured with the same driving source, which helps to simplify the structure and operation of the whole machine.

[0162] It should be noted that the above-mentioned activity time includes whether the first opening and closing member 231 and the second opening and closing member 232 are started simultaneously or sequentially; it also includes whether the first opening and closing member 231 and the second opening and closing member 232 are operated at the same speed or at different speeds.

[0163] When the activities of the first opening and closing member 231 and the second opening and closing member 232 are linked as described above, in a specific application, the switching device 230 further includes a linkage mechanism, which links the first opening and closing member 231 and the second opening and closing member 232. At this time, the driving source can be drivingly connected with one or several of the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232.

[0164] In further schemes, the linkage mechanism is arranged to drive the first opening and closing member 231 and the second opening and closing member 232 to move in the same direction during the process of turning on the air outlet air duct 213a or the air inlet air duct 110. That is, when the first opening and closing member 231 moves to the first opening position, the linkage mechanism drives the second opening and closing member 232 to move in the same direction to the second closing position; when the first opening and closing member 231 moves to the first closing position, the linkage mechanism drives the second opening and closing member 232 to move in the same direction to the second opening position. The arrangement of the same direction movement helps to simplify the complexity of the movement of the first opening and closing member 231 and the second opening and closing member 232 in structure and space, and makes the first opening and closing member 231 and the second opening and closing member 232 maintain a certain interval in their respective movement strokes as much as possible, without interfering with each other.

[0165] In view of the above, the driving source can be directly connected to one or several of the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232. Alternatively, in an embodiment, the switching device 230 further comprises a trigger member 234 connected to one or several of the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232, and the trigger member 234 is used to bear the external force (i.e. the driving source) to have a trigger stroke to drive the first opening and closing member 231 and the second opening and closing member 232 to move in the same direction under the driving of the external force. The trigger stroke can refer to the stroke that can realize the movement of the first opening and closing member 231 to the first opening position and the movement of the second opening and closing member 232 to the second closing position, or can refer to the stroke that can realize the movement of the first opening and closing member 231 to the first closing position and the movement of the second opening and closing member 232 to the second opening position. Since the trigger member 234 itself also has a certain trigger stroke, by reasonably setting the trigger stroke of the trigger member 234, the restriction on the structural design of the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 can be reduced, the structural design freedom of the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 is increased, and good adaptation between the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 and the driving source is realized.

[0166] As can be seen from the above, the specific scheme of the driving source is not limited, and can be derived from the docking action of the dust collector device 200 and the dust collecting station 100, derived from manual triggering of the user, or derived from automatic triggering of a pre-set program and the like electric control device.

[0167] Taking the case where the driving source is derived from the docking action of the dust collector device 200 and the dust collecting station 100 as an example, the trigger member 234 can be arranged at the docking position of the dust collector device 200 and the dust collecting station 100, and after the dust collector device 200 and the dust collecting station 100 are docked, the trigger member 234 is driven to perform the above-mentioned trigger stroke. At this time, the trigger stroke can be, but is not limited to, the stroke that can realize the movement of the first opening and closing member 231 to the first closing position and the movement of the second opening and closing member 232 to the second opening position. In this way, without the need for special electric control period or manual operation of the user, the linkage of the first opening and closing member 231 and the second opening and closing member 232 can be automatically realized after the dust collector device 200 and the dust collecting station 100 are docked. Specifically, when the dust collector device 200 and the dust collecting station 100 are docked, the first opening and closing member 231 is moved to the first closing position and the second opening and closing member 232 is moved to the second opening position. At this time, the trigger member 234 is arranged at the docking position of the dust collector device 200 and the dust collecting station 100, and the arrangement direction of the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232 is relatively free, and can be arranged according to the actual installation environment.

[0168] In a further solution, please refer to Figs. 7-8, the first and second open-close members 231, 232 are provided with mounting ends. The first open-close member 231 can be adapted to the cross-sectional shape of the air outlet duct 213a at the location and provided in a plate-like or column-like shape, etc.; similarly, the second open-close member 232 can be adapted to the cross-sectional shape of the air suction duct 110 at the location and provided in a plate-like or column-like shape, etc. The linkage mechanism includes a first rotating shaft 233a rotatably mounted to the dust collector 200, and the mounting ends of the first and second open-close members 231, 232 are non-rotatably mounted to the first rotating shaft 233a, so that when the first rotating shaft 233a rotates, the first and second open-close members 231, 232 are driven to rotate in the same direction. The first open-close member 231 can reach a first open position and a first closed position during rotation; the second open-close member 232 can reach a second open position and a second closed position during rotation. The trigger member 234 is connected to the first rotating shaft 233a, the first open-close member 231, and / or the second open-close member 232.

[0169] The mounting ends of the first and second open-close members 231, 232 are non-rotatably mounted to the first rotating shaft 233a, which is not limited in the implementation manner. For example, the first open-close member 231 and the first rotating shaft 233a can be integrally formed, or they can be fixedly connected in a detachable or non-detachable manner after being separately formed. For example, as shown in Figs. 7-8, the mounting end of the first open-close member 231 is sleeved on the outer side of the first rotating shaft 233a, and the sleeve joint between them is provided in a non-circular shape, or one of the sleeve joints is provided with a non-rotation protrusion, and the other is provided with a non-rotation recess matching the non-rotation protrusion.

[0170] When the first and second open-close members 231, 232 are non-rotatably sleeved on the outer side of the first rotating shaft 233a, the mounting end of the first open-close member 231, except for the part sleeved on the first rotating shaft 233a, is provided to slide against the outer peripheral wall of the first rotating shaft 233a at the corresponding position, or against the mounting end of the second open-close member 232 at the corresponding position; the second open-close member 232 is provided in the same way. In this way, there is no large gap between the first open-close member 231 and the first rotating shaft 233a, and between the second open-close member 232 and the first rotating shaft 233a, which achieves a certain dustproof and waterproof effect.

[0171] Further, the linkage mechanism further comprises a second rotating shaft 233b, a first swing lever 233c, a second swing lever 233d and a connecting rod 233e. The second rotating shaft 233b is rotatably installed on the dust collector 200 and extends in the same direction as the first rotating shaft 233a. One end of the first swing lever 233c is rotationally connected to the first rotating shaft 233a. One end of the second swing lever 233d is rotationally connected to the second rotating shaft 233b. Two ends of the connecting rod 233e are respectively rotatably connected to the other end of the first swing lever 233c and the other end of the second swing lever 233d. The trigger 234 is connected to the first swing lever 233c, the second swing lever 233d and / or the connecting rod 233e. The first rotating shaft 233a, the second rotating shaft 233b, the first swing lever 233c, the second swing lever 233d and the connecting rod 233e constitute a linkage mechanism. The first swing lever 233c and the first rotating shaft 233a, and the second swing lever 233d and the second rotating shaft 233b can be integrally formed or detachably or non-detachably connected after being separately formed. The first swing lever 233c and the connecting rod 233e, and the second swing lever 233d and the connecting rod 233e are respectively rotatably connected. When the trigger 234 is triggered by an external force to perform a triggering stroke, the first swing lever 233c, the second swing lever 233d and / or the connecting rod 233e are driven, and then the linkage mechanism is driven to operate, so as to finally drive the first opening and closing member 231 and the second opening and closing member 232 to operate.

[0172] Specifically, as shown in FIGS. 7 and 8, the trigger 234 is rotationally connected to the second rotating shaft 233b. When the trigger 234 is triggered by an external force, the second rotating shaft 233b is rotated, the second swing lever 233d is swung, the connecting rod 233e is moved, the first swing lever 233c is swung and the first rotating shaft 233a is rotated, so as to finally drive the first opening and closing member 231 and the second opening and closing member 232 to rotate in the same direction.

[0173] Further, the linkage mechanism further comprises an elastic reset member 233f, one end of the elastic reset member 233f is connected to the dust collector device 200, and the other end is connected to at least one of the first opening and closing member 231, the second opening and closing member 232, the first rotating shaft 233a, the second rotating shaft 233b, the first swing rod 233c, the second swing rod 233d, and the connecting rod 233e; under the driving of an external force, the trigger member 234 performs a triggering stroke, and drives the first opening and closing member 231 to block the air outlet air duct 213a (i.e., moves to the first closed position) and the second opening and closing member 232 to open the air outlet air duct 213a (i.e., moves to the second open position), at this time, the switching device 230 is in the first switching state; when the external force is removed, the elastic reset member 233f drives the first opening and closing member 231 to reset to open the air outlet air duct 213a (i.e., moves to the first open position) and the second opening and closing member 232 to block the air inlet air duct 110 (i.e., moves to the second closed position), at this time, the switching device 230 is in the second switching state.

[0174] Further, in an embodiment, the air duct section of the air outlet air duct 213a that is in movable cooperation with the first opening and closing member 231 is provided with a first stop protrusion, and the first opening and closing member 231 is movably arranged on the side of the first stop protrusion that is away from the air exhaust device 220; in this way, when the switching device 230 is in the first switching state, i.e., the first opening and closing member 231 blocks the air outlet air duct 213a and the second opening and closing member 232 opens the air inlet air duct 110, the first opening and closing member 231 can be tightly fitted with the first stop protrusion under the driving of the suction force of the air suction side of the air exhaust device 220, thereby increasing the blocking effect of the first opening and closing member 231 on the air outlet air duct 213a.

[0175] Similarly, the air duct section of the air inlet air duct 110 that is in movable cooperation with the second opening and closing member 232 is provided with a second stop protrusion, and the second opening and closing member 232 is movably arranged on the side of the second stop protrusion that is away from the air exhaust device 220; in this way, when the switching device 230 is in the second switching state, i.e., the first opening and closing member 231 opens the air outlet air duct 213a and the second opening and closing member 232 blocks the air inlet air duct 110, the second opening and closing member 232 can be tightly fitted with the second stop protrusion under the driving of the suction force of the air suction side of the air exhaust device 220, thereby increasing the blocking effect of the second opening and closing member 232 on the air outlet air duct 213a.

[0176] In addition, please refer to FIGS. 9-19, the disclosure further provides another embodiment of the switching device 230:

[0177] Specifically, referring to FIGS. 9-19, the switching device includes a wind guide portion 300 and an opening and closing portion 400. The wind guide portion 300 is formed with a wind guide passage 310 provided with two connection ports for communicating with external passages. The opening and closing portion 400 is movably arranged in the wind guide passage 310 to have a switching state of moving to cover one connection port and open the other connection port. In the switching state, the wind guide passage 310 constitutes a partial wind passage section of the first or second wind passage corresponding to the opened connection port, and the opening and closing portion 400 defines at least two flow passages communicated with the opened connection port.

[0178] In the technical solution provided by the present disclosure, the wind guide passage 310 formed by the wind guide portion 300 can be adapted to communicate with and connect at least two external passages, and under the movement of the opening and closing portion 400, the air flows of the two external passages can be guided to the required passage section, respectively. The opening and closing portion 400 is movable in the wind guide passage 310, and can use the internal space of the wind guide passage 310, so that the installation and movement of the opening and closing portion 400 do not occupy additional space, thereby ensuring that the overall structure of the switching device and the overall structure of the carrier product on which the switching device is installed are more compact. When the opening and closing portion 400 defines at least two flow passages communicated with the opened connection port in the switching state, each flow passage can perform targeted operations such as flow splitting, flow reversing, flow adjusting, etc. on the air flowing into or out of the external passage connected by the opened connection port, so that the switching device has more rich guiding functions in addition to the switching function, which ultimately helps the switching device to be more matched with the carrier product it refers to, and the switching device has more versatility and reliability.

[0179] It should be noted that in the above and below embodiments, although it is not limited that the passage structure must be a passage with a circular transverse cross-sectional shape, the passage structure is generally uniformly defined as having an axial direction, a radial direction, and a circumferential direction for ease of understanding.

[0180] The opening and closing portion 400 is movably arranged in the wind guide passage 310, and has a switching state of moving to open one connection port and cover the other connection port in the movement stroke of the opening and closing portion 400. Then, when the two connection ports are the first connection port 321 and the second connection port 331 as described above:

[0181] The opening and closing portion 400 has a second switching state of moving to open the first connection port 321 and cover the second connection port 331. In the second switching state, the passage between the dust storage cavity 212a and the air driving device 220 is communicated, and the passage between the dust collection cavity and the air driving device 220 is blocked, so that the dust cleaner 200 can independently perform the dust collection operation based on the passage between the dust storage cavity 212a and the air driving device 220.

[0182] The opening and closing part 400 also has a first switching state in which the first connecting port 321 is opened and the second connecting port 331 is closed. In the first switching state, the passage between the dust storage chamber 212a and the air driving device 220 is blocked and the passage between the dust collection chamber and the air driving device 220 is opened, so that the dust collection station 100 can perform the dust extraction operation based on the passage between the dust collection chamber and the air driving device 220. The first switching state is generally switched when the cleaner device 200 is docked with the dust collection station 100 or after the cleaner device 200 is docked with the dust collection station 100.

[0183] In actual application, the switching device can be provided with the second switching state or the first switching state alternatively. For example, when the opening and closing part 400 is moved to the second switching state, the first connecting port 321 is opened and the second connecting port 331 is closed; but when the opening and closing part 400 is moved to a state other than the second switching state, the first connecting port 321 and the second connecting port 331 can be both opened or both closed according to actual needs.

[0184] Of course, the switching device can also have both the second switching state and the first switching state, in which case, the opening and closing part 400 can be switched between the second switching state and the first switching state in the movement stroke. For the sake of understanding, the following will be described by taking this setting of the switching device as an example.

[0185] It can be understood that the movement of the opening and closing part 400 can not only switch between the second switching state and the first switching state, but also form at least two flow channels that are in communication with the opened connecting port. For example, the opened connecting port in FIG. 10 is the first connecting port 321.

[0186] When the first connecting port 321 is opened, the dust storage chamber 212a and the air guiding passage 310 of the cleaner device 200 are in communication. Each flow channel is generally arranged on the downstream side of the first connecting port 321. At this time, each flow channel forms at least a plurality of independent flow paths. The gas from the same source (for example, the dust storage chamber 212a) can flow in each flow channel alternatively or simultaneously. When the flow conditions such as flow direction and flow rate of each flow channel are the same, each flow channel can play a role of flow splitting; and each flow channel can be an alternative of any flow channel, so that at least one remaining flow channel can be selected when any flow channel is blocked or abnormal, and the downstream side flow communication function of the first connecting port 321 fails. Or when the flow conditions such as flow direction and flow rate of each flow channel are at least partially different, the gas can be guided to different flow channels according to actual needs, so that the gas flow is more purposeful and diverse.

[0187] In a further scheme, the side wall of the air guide passage 310 at the preset passage section is provided with a mounting hole 340, which is communicated with the air driving device 220, and specifically communicated with the air suction side of the air driving device 220. In this way, no matter whether the first connecting port 321 is opened or the second connecting port 331 is opened, the passage between the corresponding communicated dust storage cavity 212a and the air driving device 220 or the passage between the dust collection cavity and the air driving device 220 can be driven by the same air driving device 220 to realize the directional movement of the air flow, which helps to simplify the number and installation structure of the air driving device 220, so that the overall structure of the dust collector system is more compact, and the manufacturing and maintenance costs are reduced.

[0188] Based on one or more of the above embodiments, further, regarding the specific arrangement of the opening and closing part 400:

[0189] It can be understood that the specific structure, movement form, movement direction, etc. of the opening and closing part 400 can be adjusted according to the specific arrangement of the first connecting port 321 and the second connecting port 331.

[0190] For example, when the first connecting port 321 and the second connecting port 331 are both arranged on the same passage side wall of the air guide passage 310 and spaced apart along the axial direction of the air guide passage 310: in an embodiment, the opening and closing part 400 can be arranged to be translatable along the axial direction of the air guide passage 310, so as to be able to translate to be close to the first connecting port 321 and away from the second connecting port 331, and to be able to translate to be away from the first connecting port 321 and close to the second connecting port 331, to realize the movement switching between the second switching state and the first switching state. Or in an embodiment, the opening and closing part 400 can be arranged to be rotatably connected at the passage wall between the first connecting port 321 and the second connecting port 331, and substantially in the form of a lever, so that when a segment of the opening and closing part 400 rotates towards the first connecting port 321, another segment of the opening and closing part 400 is driven to rotate away from the second connecting port 331; when a segment of the opening and closing part 400 rotates towards the second connecting port 331, another segment of the opening and closing part 400 is driven to rotate away from the first connecting port 321, which can also realize the movement switching between the second switching state and the first switching state.

[0191] Or for example, when the first connection port 321 and the second connection port 331 are arranged on the two radial side walls of the air guide channel 310 and are arranged at a radial interval along the air guide channel 310, the opening and closing part 400 can be reciprocally arranged between the two connection ports. In the switching state, the opening and closing part 400 abuts against the side wall where the connection port is closed, and is spaced apart from the side wall where the connection port is opened, so as to define at least two flow channels at the spacing respectively. For example, the air guide channel 310 has a first channel side wall 320 and a second channel side wall 330 arranged oppositely in the radial direction thereof, and the first connection port 321 is arranged on the first channel side wall 320, and the second connection port 331 is arranged on the second channel side wall 330. That is, in the second switching state, the opening and closing part 400 is separated from the first channel side wall 320 to open the first connection port 321, and the opening and closing part 400 abuts against the second channel side wall 330 to close the second connection port 331. At this time, the spacing between the opening and closing part 400 and the first channel side wall 320 corresponds to the air guide channel 310 at the position being open, and constitutes at least two flow channels. Conversely, in the first switching state, the opening and closing part 400 is separated from the second channel side wall 330 to open the second connection port 331, and the opening and closing part 400 abuts against the first channel side wall 320 to close the first connection port 321. At this time, the spacing between the opening and closing part 400 and the second channel side wall 330 corresponds to the air guide channel 310 at the position being open, and constitutes at least two flow channels.

[0192] When the first connection port 321 is arranged in communication with the dust storage cavity 212a in the dust collector device 200, and the second connection port 331 is arranged in communication with the dust collection cavity in the dust collection station 100 after the dust collector device 200 and the dust collection station 100 are docked, for example: when the dust collector device 200 is not docked with the dust collection station 100, that is, the dust collector device 200 is operated independently, the opening and closing part 400 is maintained in the second switching state, that is, the opening and closing part 400 closes the second connection port 331 and opens the first connection port 321, and at this time the channel between the dust storage cavity 212a and the air driving device 220 is kept open. After the dust collector device 200 and the dust collection station 100 are docked, the opening and closing part 400 can be switched to the first switching state under the mechanical triggering of the triggering structure, or under the automatic control of the preset program, that is, the opening and closing part 400 closes the first connection port 321 and opens the second connection port 331, so that the channel between the dust collection cavity and the air driving device 220 is open.

[0193] In the above, the trigger structure can be arranged at the docking position of the dust collector device 200 and the dust collecting station 100, and be forced by the docking action of the dust collector device 200 and the dust collecting station 100 to be triggered. Alternatively, the trigger structure can be electrically connected with the sensor device and the control device, and the control device can control the trigger structure to drive the opening and closing part 400 to move after receiving the sensing signal of the sensor device.

[0194] Then, the switching of the opening and closing part 400 between the second switching state and the first switching state can be directly realized by the trigger structure or the preset program. Alternatively, in an embodiment, the trigger structure or the preset program controls the opening and closing part 400 to switch from the second switching state to the first switching state, and the opening and closing part 400 to reset from the first switching state to the second switching state can be realized by driving a resilient member 500. Based on this, in an embodiment, the switching device further comprises the resilient member 500, which is connected between the opening and closing part 400 and the air guide part 300. Under the driving of an external force, the opening and closing part 400 is driven by the external force to move from one connection port to another connection port. When the external force is removed, the opening and closing part 400 is reset by the resilient member 500. The resilient member 500 can be, for example, a spring member, a metal spring, a rubber or silicone member, etc.

[0195] The specific structure of the opening and closing part 400 is not limited, and can be, but is not limited to, designed in a plate shape, a block shape, a column shape, etc. Please refer to FIG. 13 and FIG. 19. In an embodiment, the opening and closing part 400 comprises an opening and closing body 410 and a ring-shaped step 420 protruding from the outer wall of the opening and closing body 410, and the ring-shaped step 420 divides the opening and closing body 410 into two body segments. In the switching state, one body segment is inserted into one connection port, and the corresponding side step surface of the ring-shaped step 420 abuts against the circumferential surface of the connection port to jointly cover the connection port. The opening and closing body 410 extends substantially along the line between the first connection port 321 and the second connection port 331, i.e., the first radial extension described above. The two body segments of the opening and closing body 410 divided by the ring-shaped step 420 are defined as a first body segment 411 facing the first connection port 321 and a second body segment 412 facing the second connection port 331 for ease of understanding. The step surface of the ring-shaped step 420 facing the first connection port 321 is defined as a first step surface 421, and the step surface facing the second connection port 331 is defined as a second step surface 422.

[0196] At this time, taking the second switching state as an example:

[0197] The second main body section 412 is inserted at the second connection port 331 to achieve the first sealing and covering of the second connection port 331 by the opening and closing part 400. The second step surface 422 abuts against the second channel side wall 330 to achieve the second sealing and covering of the second connection port 331 by the opening and closing part 400.

[0198] The opening and closing part 400 opens the first connection port 321 in the following manner:

[0199] In an embodiment, in the switching state, a main body section is separated from a connection port, and a corresponding side step surface of the annular step 420 is separated from the circumferential surface of the connection port to jointly open the connection port. That is, in the second switching state, the first main body section 411 is completely separated from the first connection port 321 and is located in the air guide channel 310. Similarly, the first step surface 421 of the annular step 420 is completely separated from the first channel side wall 320, and the first connection port 321 is in an open state without any obstruction.

[0200] Alternatively, in an embodiment, in the switching state, a main body section is inserted into a connection port, and a gap is formed at the inserted connection between the two, the gap being in communication between the connection port and the air guide channel 310, and a corresponding side step surface of the annular step 420 is separated from the circumferential surface of the connection port to jointly open the connection port. That is, in the second switching state, the first main body section 411 is completely inserted or partially inserted into the first connection port 321, but due to the outer diameter of the first main body section 411 being smaller than the hole diameter of the first connection port 321, a gap is formed between the outer wall of the first main body section 411 and the hole wall of the first connection port 321. The first step surface 421 is separated and spaced apart from the first channel side wall 320, so that, for example, the gas in the dust storage cavity 212a of the dust collector device 200 can flow into the air guide channel 310 through the gap after entering the first connection port 321, achieving the conduction of the first connection port 321 and the air guide channel 310.

[0201] Or in an embodiment, in the switching state, a main body section is inserted into a connecting port, and the switching device is provided with a connecting channel 430 which penetrates the connecting port and the air guide channel 310, and the corresponding side step surface of the annular step 420 is separated from the circumferential surface of the connecting port to jointly open the connecting port. That is, in the second switching state, the first main body section 411 is completely inserted or partially inserted into the first connecting port 321, and the outer diameter of the first main body section 411 can be smaller than the hole diameter of the first connecting port 321, or the outer diameter of the first main body section 411 can be at least equivalent to the hole diameter of the first connecting port 321 at the first connecting port 321. At this time, the switching device is integrally provided with the connecting channel 430 which extends at least from the first connecting port 321 to the air guide channel 310, realizing the connection of the first connecting port 321 and the air guide channel 310.

[0202] Further, taking the connecting channel 430 provided with the above as an example:

[0203] Please refer to FIG. 13, the connecting channel 430 can be formed in the inside of the switching device, and its lateral direction is substantially closed, having a first channel opening 431 penetrating to the first main body section 411, and a second channel opening 432 penetrating to the outer wall of the switching device. In the switching state, the first channel opening 431 is located in the air guide channel 310, and in the direction away from the opened connecting port, the switching device is provided with a gradually decreasing outer diameter at least at the part where the first channel opening 431 is opened. That is, in the second switching state, the first channel opening 431 is located in the air guide channel 310, and the second channel opening 432 is located in the first connecting port 321. The outer diameter of the switching device at least at the part where the first channel opening 431 is opened, that is, at the first main body section 411, is provided with a gradually increasing outer diameter in the direction close to the first connecting port 321, forming an inclined outer circumferential wall. In this way, on the one hand, the first main body section 411 can be adapted to different hole diameters of the first connecting port 321 to realize targeted insertion and sealing by the gradually increasing outer diameter; on the other hand, the first channel opening 431 can be opened on the inclined outer circumferential wall, having a larger opening area.

[0204] Please refer to FIG. 19, the connecting channel 430 can also be opened on the outer circumferential wall of the switching device, and the connecting channel 430 is provided with an opening in the lateral wall of the switching device, being substantially in the form of a slot. At this time, the connecting channel 430 can connect the first connecting port 321 and the air guide channel 310 through the opening.

[0205] It should be noted that the opening and closing body 410 and the annular step 420 in the above can be integrally formed, or can be connected after being separately formed. In addition, in order to realize the flexible abutment between the opening and closing part 400 and the air guide part 300, at least the outer wall of the main body section and / or the annular step 420 can be made of elastic material, or directly mounted with an elastic layer.

[0206] Based on any of the above embodiments, in a further scheme, the switching device further comprises an adapting part 600 for adapting the air guide part 300 to be mounted in the to-be-mounted area of the carrier product, the adapting part 600 is formed with a mounting channel 610, the mounting channel 610 is in communication with a connection port and extends in the same direction; the switching device further comprises a mounting part 700, the mounting part 700 is connected to one end of the main body section away from the annular step 420, and is accommodated in the mounting channel 610. As shown in FIGS. 10-12, the mounting channel 610 can be in communication with the first connection port 321, so as to extend the length of the first connection port 321, and form sufficient space for the mounting part 700 to be mounted.

[0207] The mounting part 700 and the opening and closing part 400 can be integrally formed, or can be connected after being separately formed. Whether the opening and closing part 400 is in the second switching state or in the first switching state, the mounting part 700 is always accommodated in the mounting channel 610, so as to assist the opening and closing part 400 to be mounted more stably and moved more smoothly.

[0208] In a further scheme, one of the inner wall of the mounting channel 610 and the outer wall of the mounting part 700 is provided with a stop protrusion 611, and the other is provided with a matching protrusion 710, the stop protrusion 611 and the matching protrusion 710 abut to limit the mounting part 700 from being pulled out of the mounting channel 610. As described above, in order to realize the flexible abutment between the inner wall of the mounting channel 610 and the outer wall of the mounting part 700, the inner wall of the mounting channel 610 and / or the outer wall of the mounting part 700 can be made of elastic material, or directly mounted with an elastic layer.

[0209] In addition, in an embodiment, the adapting part 600 is further provided with an extension channel 620 in the side wall of the mounting channel 610, the extension channel 620 extends to at least one of the radial side or the axial side of the mounting channel 610, and is adapted to be connected with the external channel of the carrier product on which the switching device is mounted. The adapting part 600 can adapt the mounting between the air guide part 300 and the carrier product (such as the dust collector 200) in the overall structure; and the extension channel 620 can adapt the communication connection between the dust storage cavity 212a and / or the front filter 243 of the dust collector 200 and the first connection port 321.

[0210] In the above embodiments, the adapter 600 is integrally formed with the air guide 300, or the adapter 600 is separately formed with the air guide 300 and then connected to the air guide 300 in a detachable or non-detachable manner. It should be noted that the above does not limit the number of structures of the air guide 300 and / or the adapter 600. For example, as shown in FIG. 12, the air guide 300 can be separately formed with the adapter 600, and the air guide 300 itself can be obtained by detachably connecting two shell structures, and the air guide 300 and the adapter 600 together define the air guide channel when connected. Alternatively, as shown in FIG. 18, the air guide 300 and the adapter 600 are at least partially integrally formed, and as described above, the air guide 300 and the adapter 600 as a whole can be obtained by detachably connecting two shell structures, and the air guide 300 and the adapter 600 together define the air guide channel when connected.

[0211] When the connection channel 430 is provided as described above, the connection channel 430 can be provided only at the first main body section 411 or can extend between the first main body section 411 and the mounting portion 700 according to actual needs. For example, as shown in FIGS. 10 and 11, the switching device is provided with the connection channel 430 extending between the mounting portion 700 and the adjacent main body section, and the connection channel 430 connects the air guide channel 310 and the mounting channel 610 when the connection port connected to the mounting channel 610 is opened.

[0212] As described above, the air guide channel 310 is provided in a ring shape. When the switching state is the second switching state, the opening and closing portion 400 maintains the air guide channel 310 to be open along the circumferential direction of the air guide channel 310 at least at the opened connection port (e.g., the first connection port 321), so as to define at least two flow channels connected to the opened connection port. At this time, the air flow entering the air guide channel 310 through the first connection port 321 can flow along one side of the air guide channel 310 at the position, forming one flow channel, or can flow along the other side of the air guide channel 310 at the position, forming another flow channel.

[0213] Since the downstream end of the flow channel is not limited to be converged together, that is, the extension length of the flow channel in the air guide channel 310 is not limited, the flow channel can be formed in a partial channel section of the air guide channel 310, and at this time, the opening and closing portion 400 maintains the air guide channel 310 to be open along the circumferential direction of the air guide channel 310. Alternatively, the flow channel can be formed in the entire air guide channel 310, and at this time, the opening and closing portion 400 maintains the air guide channel 310 to be open along the circumferential direction of the air guide channel 310.

[0214] When the air guide passage 310 is provided with the mounting hole 340 at the passage segment radially opposite to the opened connection port as described above, in a further scheme, the two connection ports can be provided at the two side walls of the same passage segment of the air guide passage 310 radially opposite to each other, and the connection ports and the mounting hole 340 are provided at the two passage segments of the air guide passage 310 radially opposite to each other. In this way, the first connection port 321, the second connection port 331 and the mounting hole 340 are arranged in sequence along the same radial direction of the annular air guide passage 310, which on the one hand helps to balance and arrange the switching device 400 and the air driving device 220 on both sides of the air guide passage 300 in an aesthetic manner, and on the other hand can make the flow conditions of the two flow channels directly formed by the two first passage segments 311 substantially the same, ensuring that the flow parameters of the gas in the two flow channels are substantially the same. Especially when the switching device is applied to a dust collector system, and the center of the annular air guide passage 310 is located on the central axis of the dust collector device 200, the disturbance caused by the flow of the gas in each flow channel can be more balanced or directly offset, avoiding the situation that the dust collector device 200 has greater disturbance and noise on one side, and reducing the user experience.

[0215] In addition to the air driving device 220 as described above, the dust collector device 200 can further include a pre-filter 243. The pre-filter 243 is generally annularly arranged at the downstream end of the dust storage chamber 212a, and the gas flowing through the dust storage chamber 212a enters the center of the pre-filter 243 and is finally dispersed and discharged outwardly along the radial direction of the pre-filter 243, so that the solid residues carried in the gas are trapped in the dust storage chamber 212a under the action of the pre-filter 243.

[0216] When the air guide passage 310 is annularly arranged as described above, and the carrier product on which the switching device is installed is the dust collector device 200, the air guide passage 310 can be optionally arranged around the outer periphery of the pre-filter 243, so that the gas discharged outwardly through the pre-filter 243 can enter the air guide passage 310 through, for example, the first connection port 321.

[0217] When the adapter 600 is further included as described above, the adapter 600 can realize the adaptive installation between the air guide passage 300 and the pre-filter 243 on the dust collector device 200. The installation passage 610 of the adapter 600 extends in the extension direction of, for example, the first connection port 321 provided on the air guide passage 300, and the extension passage 620 extends in the air outlet direction of the downstream side of the pre-filter 243 on the dust collector device 200.

[0218] Specifically, please refer to FIGS. 10-12. In an embodiment, the air guide passage 310 extends in a ring shape; the pre-filter 243 is arranged in a cylinder shape on a radial side of the air guide passage 310 and is located in an inner region of the ring of the air guide passage 310. That is, the air guide passage 310 and the pre-filter 243 at least partially overlap in a horizontal projection, which helps to shorten the space occupation of the air guide passage 310 and the pre-filter 243 in the vertical direction.

[0219] At this time, the pre-filter 243 occupies the inner region of the ring of the air guide passage 310. Since the adapter 600 is arranged as described above and the mounting passage 610 is formed in the adapter 600, the mounting passage 610 also needs to occupy the inner region of the ring of the air guide passage 310 to a certain extent. Therefore, in a further solution, the horizontal cross section of the pre-filter 243 is in a flat circular shape and is arranged eccentrically in the inner region of the ring of the air guide passage 310 to make room for the connection port and / or the mounting passage 610 extending through the extending passage 620.

[0220] Alternatively, specifically, please refer to FIGS. 14-17. In an embodiment, the air guide passage 310 extends in a ring shape; the pre-filter 243 is arranged in a cylinder shape on an axial side of the air guide passage 310 and the horizontal projection of the pre-filter 243 on the axial direction of the air guide passage 310 falls in the inner region of the ring of the air guide passage 310. That is, the horizontal projections of the air guide passage 310 and the pre-filter 243 are staggered in the vertical direction, and the pre-filter 243 can be arranged above or below the air guide passage 310. In this way, the horizontal projection of the pre-filter 243 still falls in the inner region of the ring of the air guide passage 310 or at least partially overlaps with the air guide passage 310, but does not occupy the inner region of the ring of the air guide passage 310. Therefore, the pre-filter 243 is not limited in size and can be in a conventional form. The extending passage 620 extends from the radial direction of the pre-filter 243, bends upward or downward, and then communicates with the radial direction or the axial direction of the mounting passage 610.

[0221] In addition, please refer to FIGS. 9-19. The disclosure also provides another embodiment of the switching device 230:

[0222] Specifically, please refer to FIGS. 9-19. The switching device includes an air guide part 300 and an opening and closing part 400. The air guide part 300 is formed with an air guide passage 310, which is provided with two connection ports for communicating with external passages. The opening and closing part 400 is movably arranged in the air guide passage 310 to have a switching state in which the opening and closing part 400 covers one connection port and opens the other connection port. In the switching state, the opening and closing part 400 defines at least two flow channels that communicate with the opened connection port.

[0223] The air guide part 300 forms an air guide channel 310 which can be connected to at least two external channels, and under the cooperation of the opening and closing part 400, the air flow of the two external channels can be guided to the required channel section respectively. The opening and closing part 400 can move in the air guide channel 310, and can use the internal space of the air guide channel 310, so that the installation and movement of the opening and closing part 400 does not occupy additional space, thereby ensuring that the overall structure of the switching device and the carrier product installed with the switching device is more compact. When the opening and closing part 400 defines at least two flow channels that are in communication with the opened connection port in the switching state, each flow channel can perform targeted operations such as flow splitting, flow reversing, flow adjusting, etc. on the gas flowing into or out of the external channel connected to the opened connection port, thereby making the switching device have more rich guiding functions in addition to the switching function, ultimately helping the switching device to be more matched with the carrier product it refers to, and the switching device to be more universal and reliable.

[0224] It should be noted that in the above and below embodiments, although it is not limited that the channel structure must be a channel with a circular transverse cross-sectional shape, the channel structure is generally uniformly defined as having an axial direction, a radial direction, and a circumferential direction for ease of understanding.

[0225] The opening and closing part 400 is movably arranged in the air guide channel 310, and in the movement stroke of the opening and closing part 400, there is a switching state in which the opening and closing part 400 is moved to open a connection port and cover another connection port. Then when the two connection ports are the first connection port 321 and the second connection port 331 as described above:

[0226] The opening and closing part 400 has a second switching state in which the opening and closing part 400 is moved to open the first connection port 321 and cover the second connection port 331. In the second switching state, the channel between the dust storage cavity 212a and the air driving device 220 is open and the channel between the dust collection cavity and the air driving device 220 is blocked, and the dust cleaner device 200 can independently perform a dust suction operation based on the channel between the dust storage cavity 212a and the air driving device 220.

[0227] The opening and closing part 400 also has a first switching state in which the opening and closing part 400 is moved to cover the first connection port 321 and open the second connection port 331. In the first switching state, the channel between the dust storage cavity 212a and the air driving device 220 is blocked and the channel between the dust collection cavity and the air driving device 220 is open, and the dust collection station 100 can perform a dust extraction operation based on the channel between the dust collection cavity and the air driving device 220. The first switching state is generally formed when the dust cleaner device 200 and the dust collection station 100 are docked, or after the dust cleaner device 200 and the dust collection station 100 are docked.

[0228] In actual application, the switching device can be provided with the second switching state or the first switching state alternatively. Taking the second switching state as an example, when the opening and closing part 400 is moved to the second switching state, the first connecting port 321 is opened and the second connecting port 331 is closed; but when the opening and closing part 400 is moved to a state other than the second switching state, according to actual needs, the first connecting port 321 and the second connecting port 331 can be both opened or both closed.

[0229] Of course, the switching device can also have both the second switching state and the first switching state, and in this case, the opening and closing part 400 can be switched between the second switching state and the first switching state in the moving stroke. For the sake of understanding, the following will take this setting of the switching device as an example for illustration.

[0230] It can be understood that the movement of the opening and closing part 400 can not only switch between the second switching state and the first switching state, but also form at least two flow channels that are in communication with the opened connecting port. Taking the opened connecting port in FIG. 10 as the first connecting port 321 for auxiliary explanation:

[0231] When the first connecting port 321 is opened, the dust storage cavity 212a and the air guide channel 310 of the dust collector device 200 are in communication. Each flow channel is generally arranged downstream of the first connecting port 321. At this time, each flow channel forms at least a plurality of independent flow paths. The gas from the same source (e.g. the dust storage cavity 212a) passing through the first connecting port 321 can flow in each flow channel alternatively or simultaneously. When the flow conditions such as flow direction, flow rate, etc. of each flow channel are the same, each flow channel can play a role of flow splitting; and each flow channel can be an alternative of any flow channel, so that when any flow channel is blocked or abnormal, at least one remaining flow channel can be selected to ensure that the downstream flow communication function of the first connecting port 321 fails. Or when the flow conditions such as flow direction, flow rate, etc. of each flow channel are at least partially different, the gas can be guided to different flow channels according to actual needs, so that the flow of the gas is more purposeful and diverse.

[0232] In a further scheme, the side wall of the air guide passage 310 at the preset passage section is provided with a mounting hole 340, which is communicated with the air driving device 220, and specifically communicated with the air suction side of the air driving device 220. In this way, no matter whether the first connecting port 321 is opened or the second connecting port 331 is opened, the passage between the corresponding communicated dust storage cavity 212a and the air driving device 220 or the passage between the dust collection cavity and the air driving device 220 can be driven by the same air driving device 220 to realize the directional movement of the air flow, which helps to simplify the number and installation structure of the air driving device 220, so that the overall structure of the dust collector system is more compact, and the manufacturing and maintenance costs are reduced.

[0233] Based on one or more of the above embodiments, further, regarding the specific arrangement of the opening and closing part 400:

[0234] It can be understood that the specific structure, movement form, movement direction, etc. of the opening and closing part 400 can be adjusted according to the specific arrangement of the first connecting port 321 and the second connecting port 331.

[0235] For example, when the first connecting port 321 and the second connecting port 331 are both arranged on the same passage side wall of the air guide passage 310 and spaced apart along the axial direction of the air guide passage 310: in an embodiment, the opening and closing part 400 can be arranged to be translatable along the axial direction of the air guide passage 310, so as to be able to translate to be close to the first connecting port 321 and away from the second connecting port 331, and to be able to translate to be away from the first connecting port 321 and close to the second connecting port 331, to realize the active switching between the second switching state and the first switching state. Or in an embodiment, the opening and closing part 400 can be arranged to be rotatably connected at the passage wall between the first connecting port 321 and the second connecting port 331, and substantially in the form of a lever, so that when a segment of the opening and closing part 400 rotates towards the first connecting port 321, another segment of the opening and closing part 400 is driven to rotate away from the second connecting port 331; when a segment of the opening and closing part 400 rotates towards the second connecting port 331, another segment of the opening and closing part 400 is driven to rotate away from the first connecting port 321, which can also realize the active switching between the second switching state and the first switching state.

[0236] Or for example, when the first connection port 321 and the second connection port 331 are arranged on the two radial side walls of the air guide channel 310 and are arranged at a radial interval along the air guide channel 310, the opening and closing part 400 can be reciprocally arranged between the two connection ports. In the switching state, the opening and closing part 400 abuts against the side wall where the connection port is closed, and is spaced apart from the side wall where the connection port is opened, so as to define at least two flow channels at the spacing respectively. For example, the air guide channel 310 has a first channel side wall 320 and a second channel side wall 330 arranged oppositely in the radial direction thereof, and the first connection port 321 is arranged on the first channel side wall 320, and the second connection port 331 is arranged on the second channel side wall 330. That is, in the second switching state, the opening and closing part 400 is separated from the first channel side wall 320 to open the first connection port 321, and the opening and closing part 400 abuts against the second channel side wall 330 to close the second connection port 331. At this time, the spacing between the opening and closing part 400 and the first channel side wall 320 corresponds to the air guide channel 310 at the position being open, and constitutes at least two flow channels. Conversely, in the first switching state, the opening and closing part 400 is separated from the second channel side wall 330 to open the second connection port 331, and the opening and closing part 400 abuts against the first channel side wall 320 to close the first connection port 321. At this time, the spacing between the opening and closing part 400 and the second channel side wall 330 corresponds to the air guide channel 310 at the position being open, and constitutes at least two flow channels.

[0237] When the first connection port 321 is arranged in communication with the dust storage cavity 212a in the dust collector device 200, and the second connection port 331 is arranged in communication with the dust collection cavity in the dust collection station 100 after the dust collector device 200 and the dust collection station 100 are docked, for example: when the dust collector device 200 is not docked with the dust collection station 100, that is, the dust collector device 200 is operated independently, the opening and closing part 400 is maintained in the second switching state, that is, the opening and closing part 400 closes the second connection port 331 and opens the first connection port 321, and at this time the channel between the dust storage cavity 212a and the air driving device 220 is kept open. After the dust collector device 200 and the dust collection station 100 are docked, the opening and closing part 400 can be switched to the first switching state under the mechanical triggering of the triggering structure, or under the automatic control of the preset program, that is, the opening and closing part 400 closes the first connection port 321 and opens the second connection port 331, so that the channel between the dust collection cavity and the air driving device 220 is open.

[0238] In the above, the trigger structure can be arranged at the docking position of the dust collector device 200 and the dust collecting station 100, and be forced by the docking action of the dust collector device 200 and the dust collecting station 100 to be triggered. Alternatively, the trigger structure can be electrically connected with the sensor device and the control device, and the control device can control the trigger structure to drive the opening and closing part 400 to move after receiving the sensing signal of the sensor device.

[0239] Then, the switching of the opening and closing part 400 between the second switching state and the first switching state can be directly realized by the trigger structure or the preset program. Alternatively, in an embodiment, the trigger structure or the preset program controls the opening and closing part 400 to switch from the second switching state to the first switching state, and the opening and closing part 400 to reset from the first switching state to the second switching state can be realized by driving a resilient member 500. Based on this, in an embodiment, the switching device further comprises the resilient member 500, which is connected between the opening and closing part 400 and the air guide part 300. Under the driving of an external force, the opening and closing part 400 is driven by the external force to move from one connection port to another connection port. When the external force is removed, the opening and closing part 400 is reset by the resilient member 500. The resilient member 500 can be, for example, a spring member, a metal spring, a rubber or silicone member, etc.

[0240] The specific structure of the opening and closing part 400 is not limited, and can be, but is not limited to, designed in a plate shape, a block shape, a column shape, etc. Please refer to FIG. 13 and FIG. 19. In an embodiment, the opening and closing part 400 comprises an opening and closing body 410 and a ring-shaped step 420 protruding from the outer wall of the opening and closing body 410, and the ring-shaped step 420 divides the opening and closing body 410 into two body segments. In the switching state, one body segment is inserted into one connection port, and the corresponding side step surface of the ring-shaped step 420 abuts against the circumferential surface of the connection port to jointly cover the connection port. The opening and closing body 410 extends substantially along the line between the first connection port 321 and the second connection port 331, i.e., the first radial extension described above. The two body segments of the opening and closing body 410 divided by the ring-shaped step 420 are defined as a first body segment 411 facing the first connection port 321 and a second body segment 412 facing the second connection port 331 for ease of understanding. The step surface of the ring-shaped step 420 facing the first connection port 321 is defined as a first step surface 421, and the step surface facing the second connection port 331 is defined as a second step surface 422.

[0241] At this time, taking the second switching state as an example:

[0242] The second main body section 412 is inserted at the second connection port 331 to achieve the first sealing and covering of the second connection port 331 by the opening and closing part 400. The second step surface 422 abuts against the second channel side wall 330 to achieve the second sealing and covering of the second connection port 331 by the opening and closing part 400.

[0243] The opening and closing part 400 opens the first connection port 321 in the following manner:

[0244] In an embodiment, in the switching state, a main body section is separated from being arranged outside a connection port, and a corresponding side step surface of the annular step 420 is separated from the peripheral side surface of the connection port to jointly open the connection port. That is, in the second switching state, the first main body section 411 can be completely separated from outside the first connection port 321 and arranged in the air guide channel 310. Similarly, the first step surface 421 of the annular step 420 is completely separated from the first channel side wall 320, and at this time, the first connection port 321 is not blocked and is in an open state.

[0245] In an embodiment, in the switching state, a main body section is separated from being arranged outside a connection port, and a corresponding side step surface of the annular step 420 is separated from the peripheral side surface of the connection port to jointly open the connection port. That is, in the second switching state, the first main body section 411 can be completely separated from outside the first connection port 321 and arranged in the air guide channel 310. Similarly, the first step surface 421 of the annular step 420 is completely separated from the first channel side wall 320, and at this time, the first connection port 321 is not blocked and is in an open state.

[0246] Or in an embodiment, in the switching state, a main body section is inserted into a connecting port, and the switching device is provided with a connecting channel 430 which penetrates the connecting port and the air guide channel 310, and the corresponding side step surface of the annular step 420 is separated from the circumferential surface of the connecting port to jointly open the connecting port. That is, in the second switching state, the first main body section 411 is completely inserted or partially inserted into the first connecting port 321, and the outer diameter of the first main body section 411 can be smaller than the hole diameter of the first connecting port 321, or the outer diameter of the first main body section 411 can be at least equivalent to the hole diameter of the first connecting port 321 at the first connecting port 321. At this time, the switching device is integrally provided with the connecting channel 430 which extends at least from the first connecting port 321 to the air guide channel 310, realizing the connection of the first connecting port 321 and the air guide channel 310.

[0247] Further, taking the connecting channel 430 provided with the above as an example:

[0248] Please refer to FIG. 13, the connecting channel 430 can be formed in the inside of the switching device, and its lateral direction is substantially closed, having a first channel opening 431 which penetrates to the first main body section 411, and a second channel opening 432 which penetrates to the outer wall of the switching device. In the switching state, the first channel opening 431 is located in the air guide channel 310, and in the direction away from the opened connecting port, the switching device is provided with a gradually decreasing outer diameter at least at the part where the first channel opening 431 is opened. That is, in the second switching state, the first channel opening 431 is located in the air guide channel 310, and the second channel opening 432 is located in the first connecting port 321. The outer diameter of the switching device at least at the part where the first channel opening 431 is opened, that is, the first main body section 411, is provided with a gradually increasing outer diameter in the direction close to the first connecting port 321, forming an inclined outer circumferential wall. In this way, on the one hand, the gradually increasing outer diameter of the first main body section 411 can be adapted to the different hole diameters of the first connecting port 321 to realize targeted insertion and sealing; on the other hand, the first channel opening 431 can be opened on the inclined outer circumferential wall, having a larger opening area.

[0249] Please refer to FIG. 19, the connecting channel 430 can also be opened on the outer circumferential wall of the switching device, and the connecting channel 430 is provided with an opening in the lateral wall of the switching device, being substantially in the form of a slot. At this time, the connecting channel 430 can connect the first connecting port 321 and the air guide channel 310 through the opening.

[0250] It should be noted that the opening and closing body 410 and the annular step 420 in the above can be integrally formed, or can be connected after being separately formed. In addition, in order to realize the flexible abutment between the opening and closing part 400 and the air guide part 300, at least the outer wall of the main body section and / or the annular step 420 can be made of elastic material, or directly mounted with an elastic layer.

[0251] Based on any of the above embodiments, in a further scheme, the switching device further comprises an adapting part 600 for adapting the air guide part 300 to be mounted in the to-be-mounted area of the carrier product, the adapting part 600 is formed with a mounting channel 610, the mounting channel 610 is in communication with a connection port and extends in the same direction; the switching device further comprises a mounting part 700, the mounting part 700 is connected to one end of the main body section away from the annular step 420, and is accommodated in the mounting channel 610. As shown in FIGS. 10-12, the mounting channel 610 can be in communication with the first connection port 321, so as to extend the length of the first connection port 321, and form sufficient space for the mounting part 700 to be mounted.

[0252] The mounting part 700 and the opening and closing part 400 can be integrally formed, or can be connected after being separately formed. Whether the opening and closing part 400 is in the second switching state or in the first switching state, the mounting part 700 is always accommodated in the mounting channel 610, so as to assist the opening and closing part 400 to be mounted more stably and moved more smoothly.

[0253] In a further scheme, one of the inner wall of the mounting channel 610 and the outer wall of the mounting part 700 is provided with a stop protrusion 611, and the other is provided with a matching protrusion 710, the stop protrusion 611 and the matching protrusion 710 abut to limit the mounting part 700 from being pulled out of the mounting channel 610. As described above, in order to realize the flexible abutment between the inner wall of the mounting channel 610 and the outer wall of the mounting part 700, the inner wall of the mounting channel 610 and / or the outer wall of the mounting part 700 can be made of elastic material, or directly mounted with an elastic layer.

[0254] In addition, in an embodiment, the adapting part 600 is further provided with an extension channel 620 in the side wall of the mounting channel 610, the extension channel 620 extends to at least one of the radial side or the axial side of the mounting channel 610, and is adapted to be connected with the external channel of the carrier product on which the switching device is mounted. The adapting part 600 can adapt the mounting between the air guide part 300 and the carrier product (such as the dust collector 200) in the overall structure; and the extension channel 620 can adapt the communication connection between the dust storage cavity 212a and / or the front filter 243 of the dust collector 200 and the first connection port 321.

[0255] In the above embodiments, the adapter 600 is integrally formed with the air guide 300, or the adapter 600 is separately formed with the air guide 300 and then connected to the air guide 300 in a detachable or non-detachable manner. It should be noted that the above does not limit the number of structures of the air guide 300 and / or the adapter 600. For example, as shown in FIG. 12, the air guide 300 can be separately formed with the adapter 600, and the air guide 300 itself can be obtained by detachably connecting two shell structures, and the air guide 300 and the adapter 600 together define the air guide channel when connected. Alternatively, as shown in FIG. 18, the air guide 300 and the adapter 600 are at least partially integrally formed, and as described above, the air guide 300 and the adapter 600 as a whole can be obtained by detachably connecting two shell structures, and the air guide 300 and the adapter 600 together define the air guide channel when connected.

[0256] When the connection channel 430 is provided as described above, the connection channel 430 can be provided only at the first main body section 411 or can extend between the first main body section 411 and the mounting portion 700 according to actual needs. For example, as shown in FIGS. 10 and 11, the switching device is provided with the connection channel 430 extending between the mounting portion 700 and the adjacent main body section, and the connection channel 430 connects the air guide channel 310 and the mounting channel 610 when the connection port connected to the mounting channel 610 is opened.

[0257] As described above, the air guide channel 310 is provided in a ring shape. When the switching state is the second switching state, the opening and closing portion 400 maintains the air guide channel 310 to be open along the circumferential direction of the air guide channel 310 at least at the opened connection port (e.g., the first connection port 321), so as to define at least two flow channels connected to the opened connection port. At this time, the air flow entering the air guide channel 310 through the first connection port 321 can flow along one side of the air guide channel 310 at the position, forming one flow channel, or can flow along the other side of the air guide channel 310 at the position, forming another flow channel.

[0258] Since the downstream end of the flow channel is not limited to be converged together, that is, the extension length of the flow channel in the air guide channel 310 is not limited, the flow channel can be formed in a partial channel section of the air guide channel 310, and at this time, the opening and closing portion 400 maintains the air guide channel 310 to be open along the circumferential direction of the air guide channel 310. Alternatively, the flow channel can be formed in the entire air guide channel 310, and at this time, the opening and closing portion 400 maintains the air guide channel 310 to be open along the circumferential direction of the air guide channel 310.

[0259] When the air guide passage 310 is provided with the mounting hole 340 at the passage segment radially opposite to the opened connection port as described above, in a further scheme, the two connection ports can be provided at the two side walls of the same passage segment of the air guide passage 310 radially opposite to each other, and the connection ports and the mounting hole 340 are provided at the two passage segments of the air guide passage 310 radially opposite to each other. In this way, the first connection port 321, the second connection port 331 and the mounting hole 340 are arranged in sequence along the same radial direction of the annular air guide passage 310, which on the one hand helps to balance and arrange the switching device 400 and the air driving device 220 on both sides of the air guide passage 300 in an aesthetic manner, and on the other hand can make the flow conditions of the two flow channels directly formed by the two first passage segments 311 substantially the same, so as to ensure that the flow parameters of the gas in the two flow channels are substantially the same. Especially when the switching device is applied to a dust collector system and the center of the annular air guide passage 310 is located on the central axis of the dust collector device 200, the disturbance caused by the flow of the gas in each flow channel can be more balanced or directly offset, avoiding the situation that the dust collector device 200 has greater disturbance and noise on one side, and reducing the user experience.

[0260] In addition to the air driving device 220 as described above, the dust collector device 200 can further include a pre-filter 243. The pre-filter 243 is generally annularly arranged at the downstream end of the dust storage chamber 212a, and the gas flowing through the dust storage chamber 212a enters the center of the pre-filter 243 and is finally dispersed and discharged outwardly along the radial direction of the pre-filter 243, so that the solid residues carried in the gas are trapped in the dust storage chamber 212a under the action of the pre-filter 243.

[0261] When the air guide passage 310 is annularly arranged as described above, and the carrier product on which the switching device is installed is the dust collector device 200, the air guide passage 310 can be optionally arranged around the outer periphery of the pre-filter 243, so that the gas discharged outwardly through the pre-filter 243 can enter the air guide passage 310 through, for example, the first connection port 321.

[0262] When the adapter 600 is further included as described above, the adapter 600 can realize the adaptive installation between the air guide passage 300 and the pre-filter 243 on the dust collector device 200. The installation passage 610 of the adapter 600 extends in the extension direction of, for example, the first connection port 321 provided on the air guide passage 300, and the extension passage 620 extends in the air outlet direction of the downstream side of the pre-filter 243 on the dust collector device 200.

[0263] Specifically, as shown in FIGS. 10-12, in an embodiment, the air guide passage 310 extends in a ring shape; the pre-filter 243 is arranged in a cylindrical shape on a radial side of the air guide passage 310 and is located in an inner region of the ring of the air guide passage 310. That is, the air guide passage 310 and the pre-filter 243 at least partially coincide in a horizontal projection, which helps to shorten the space occupation of the air guide passage 310 and the pre-filter 243 in a vertical direction.

[0264] At this time, the pre-filter 243 occupies the inner region of the ring of the air guide passage 310. Since the fitting portion 600 is arranged as described above and the mounting passage 610 is formed in the fitting portion 600, the mounting passage 610 also needs to occupy the inner region of the ring of the air guide passage 310 to a certain extent. Therefore, in a further solution, the pre-filter 243 is arranged in an eccentric manner in the inner region of the ring of the air guide passage 310 in a flattened circular shape, so as to provide space for the connection port and / or the mounting passage 610 extending through the extending passage 620.

[0265] Alternatively, as shown in FIGS. 14-17, in an embodiment, the air guide passage 310 extends in a ring shape; the pre-filter 243 is arranged in a cylindrical shape on an axial side of the air guide passage 310 and the horizontal projection of the pre-filter 243 falls in the inner region of the ring of the air guide passage 310. That is, the horizontal projection of the air guide passage 310 and the pre-filter 243 is staggered in a vertical direction, and the pre-filter 243 can be arranged above or below the air guide passage 310. In this way, the vertical projection of the pre-filter 243 still falls in the inner region of the ring of the air guide passage 310 or at least partially coincides with the air guide passage 310, but does not occupy the inner region of the ring of the air guide passage 310. Therefore, the pre-filter 243 is not limited in size and can be used in a conventional form. The extending passage 620 extends from the pre-filter 243 in a radial direction and then bends upward or downward to communicate with the mounting passage 610 in a radial direction or an axial direction.

[0266] In view of any of the above embodiments, in a further aspect, the connecting air duct 214 and the air suction duct 110 share at least a partial air duct section, forming a shared air duct section 215a, the connecting air duct 214 has a remaining air duct section other than the shared air duct section 215a, forming a remaining air suction section 215b, and the air suction duct 110 has a remaining air suction section 111a other than the shared air duct section 215a; the air suction side of the air driving device 220 is connected to the shared air duct section 215a, and the switching device 230 is movably arranged at the remaining air suction section 215b and the remaining air suction section 111a. In this way, the above-mentioned arrangement of the switching device 230 in the above embodiments can be specifically arranged at the remaining air suction section 215b and / or the remaining air suction section 111a. For example, when the switching device 230 includes the first opening and closing member 231 and the second opening and closing member 232, the first opening and closing member 231 can be arranged at the remaining air suction section 215b, and the second opening and closing member 232 can be arranged at the remaining air suction section 111a.

[0267] In addition, in view of the above embodiments, it should be noted that the air driving device 220 drives the air to enter the dust collection cavity from the dust storage cavity 212a to form the dust extraction air flow path. At this time, after the dust collector device 200 is connected to the dust collection station 100, the air inlet duct of the air inlet part 211, the dust storage cavity 212a of the dust storage part 212, and the dust collection cavity of the dust collection station 100 are in communication. Under the driving of the air driving device 220, the dust extraction air flow path is directly formed by the air flow sucked from the external environment by the air inlet part 211.

[0268] Alternatively, the source of the air driven by the air driving device 220 can be directly from other structures other than the air inlet duct of the air inlet part 211. In an embodiment, one or more auxiliary air inlets are arranged at one or more positions on the air flow path between the dust storage cavity 212a and the air suction side 221 of the air driving device 220. The auxiliary air inlet can be in communication with the external environment of the dust collector device 200. The auxiliary air inlet is arranged to be different from the air inlet duct of the air inlet part 211. At this time, after the dust collector device 200 is connected to the dust collection station 100, under the driving of the air driving device 220, the dust extraction air flow path is directly formed by the air flow sucked from the external environment by the auxiliary air inlet.

[0269] Specifically, when multiple filter members are arranged as described above, at least one auxiliary air inlet can be arranged upstream of each filter member. In this way, in the dust collection state, the air flow sucked into the dust collector device 200 through the auxiliary air inlet will pass through each filter member in turn, and the dust and other dirt remaining on each filter member will be blown off, achieving cleaning of each filter member.

[0270] And / or, when multiple filter pieces are provided as described above, at least one auxiliary air inlet can be provided downstream of each filter piece. In this way, in the dust extraction state, the airflow will also blow off the dust and other dirt remaining on each filter piece, achieving cleaning of each filter piece.

[0271] The above merely describes preferred embodiments of the present disclosure, and does not limit the patent scope of the present disclosure. Any equivalent structural transformation made by using the disclosure specification and the drawings, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present disclosure.
