[0006] 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 out the 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.

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.

[0153] 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.

[0154] The air inlet part 211 is a structural component through which external gas 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.

[0155] 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. The air inlet part 211 and the air inlet duct formed inside can extend and be arranged along the horizontal direction.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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). 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.

[0160] 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.

[0161] 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 collecting 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.

[0162] In addition, the dust collector device 200 and / or the dust collecting 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.

[0163] Of course, according to actual needs, the dust collector device 200 and / or the dust collecting 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 work 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 collecting station 100, and is triggered and forms a sensing signal when the dust collector device 200 and the dust collecting station 100 are docked.

[0164] Further, in view of any one or more embodiments of the dust collector device 200 described above, the dust collecting 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 collecting station 100, and a second working state after being docked with the dust collecting station 100. When in the second working state, the dust collecting station 100 can perform a plurality of preset operations on the dust collector device 200 under the driving of the preset program, or in response to the trigger instruction of the user. The preset operations can be but not limited to charging, cleaning, dust extraction, etc.

[0165] In view of the above one or more embodiments of the dust collector system, in order to overcome the drawbacks in 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.

[0166] Specific embodiment 1:

[0167] 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 in one or more of the above embodiments.

[0168] Specifically, the dust collector system includes a dust collection station 100 and a dust collector device 200, the dust collector device 200 includes a gas driving device 220; after the dust collector device 200 is docked with the dust collection station 100, the gas driving device 220 acts on the dust collection station 100 to generate negative pressure in at least part of the area in the dust collection station 100.

[0169] In the design, after the dust collector device 200 is docked with the dust collection station 100, the dust collection station 100 can reasonably utilize the gas driving device 220 fixed on the dust collector device 200 to generate negative pressure in at least part of the area in the dust collection station 100, thereby facilitating the dust collection station 100 to perform operations such as dust extraction, compression of dirt, dust discharge, etc. by utilizing the negative pressure generated in the area, and the dust collection station 100 does not need to additionally arrange structures such as a fan, etc., so that the structure of the dust collection station 100 as a whole can be more simplified and light, and the maintenance cost of the dust collection station 100 as a whole is lower.

[0170] It should be noted that in the following embodiments:

[0171] The gas driving device 220 is generally pre-integrated in the casing of the dust collector device 200, which helps to compact the structure. However, it can be understood that the above does not constitute a limitation on the application of the gas driving device 220 in the dust collector device 200 in the first working state. According to actual needs, the gas driving device 220 can be in a state of stopping running on the dust collector device 200 when the dust collector device 200 is in the first working state, i.e. not applied at any area in the dust collector device 200. Or a second area is defined in the dust collector device 200, and the gas driving device 220 acts on the second area when the dust collector device 200 is in the first working state, which can form positive pressure or negative pressure at the second area.

[0172] Therefore, the specific form of the second region is not limited, for example, when the air driving device 220 is used to drive the air to enter the air inlet, pass through the dust storage cavity 212a and the air outlet duct 213a, and finally be discharged outwardly through the air outlet, the second region can specifically refer to the air inlet duct, the dust storage cavity 212a and the air outlet duct 213a as a whole. For example, when the air driving device 220 is used to compress the dirt in the dust storage cavity 212a, the second region can refer to the dust storage cavity 212a. For example, when the air driving device 220 is used to clean the dirt remaining on each filter element, the second region can refer to the chamber in which each filter element is accommodated in the cleaner device 200. No further elaboration is made.

[0173] When the cleaner device 200 and the dust collecting station 100 are docked, the air driving device 220 acts on at least a partial region in the dust collecting station 100. The dust collecting station 100 is specifically defined to have a first region, and after the cleaner device 200 and the dust collecting station 100 are docked, the air driving device 220 at least acts in the first region and forms a negative pressure in the first region.

[0174] In the above embodiment, the cleaner device 200 and the dust collecting station 100 are docked, which means that the cleaner device 200 and the dust collecting station 100 start the docking action. Therefore, the timing of the air driving device 220 acting in the first region is not limited, which can be associated with the docking action of the cleaner device 200 and the dust collecting station 100, and the time point of triggering can be at the same time when the cleaner device 200 and the dust collecting station 100 start the docking action, or at the same time when the docking action is completed, or within a certain time period after the docking action is completed. The triggering mode of the air driving device 220 acting in the first region is also not limited, which can be directly triggered by the docking action of the cleaner device 200 and the dust collecting station 100, or manually triggered by the user, or automatically triggered by the preset program control (independently executed by the control device or cooperatively executed by the control device and the sensor).

[0175] After the dust collector device 200 and the dust collecting station 100 are docked, the air driving device 220 can selectively open or block the air suction side 221 and the first area. It can be understood that when the dust collector device 200 and the dust collecting station 100 are docked, the air suction side 221 of the air driving device 220 can be directly or indirectly connected to the first area through a duct structure. However, whether the connection between the two is in an open state or a blocked state can be manually or automatically selected by the user. When the user manually or automatically controls the air suction side 221 of the air driving device 220 to be open to the first area, the air suction side 221 of the air driving device 220 directly acts on the first area and forms a negative pressure in the first area. When the user manually or automatically controls the air suction side 221 of the air driving device 220 to be blocked from the first area, the air suction side 221 of the air driving device 220 can not currently act on the first area. There are many ways to switch between the open state and the blocked state, which will be described in detail below and will not be repeated here.

[0176] In addition, when the first area and the second area are provided:

[0177] In an application, the first area and the second area can be blocked from each other. At this time, the first area performs the operation required by itself using the negative pressure generated by the air driving device 220. The operation is, for example, to compress the material in the first area, to transfer the material in the first area, or to transfer the material in the area other than the second area to the first area. However, it should be noted that at this time, it is not limited whether the air driving device 220 also acts on the second area. According to actual needs, the air driving device 220 can not act on the second area, or can act on the second area and form a positive pressure or a negative pressure in the second area.

[0178] Of course, in another application, the first area and the second area can be open to each other. The air driving device 220 generates a negative pressure at least in the first area. It should be noted that at this time, it is not limited whether the air driving device 220 necessarily acts on the second area. However, since the first area and the second area are open to each other, the negative pressure in the first area can or can not affect the air pressure in the second area. The air pressure effect can be generally used to transfer the material in the second area to the first area as described in the following embodiments, or can not transfer the material.

[0179] In view of the above, it is emphasized that, at least after the cleaner device 200 is docked with the dust collection station 100, the first region and the second region can be kept in the isolation state and cannot be switched to the conduction state; or the first region and the second region can be kept in the conduction state and cannot be switched to the isolation state; or the first region and the second region can be switched between the isolation state and the conduction state at will. Similarly, the switching between the isolation state and the conduction state can be manually triggered by the user or automatically triggered by the program.

[0180] Similarly, when the first region and the second region are provided as described above, and the air driving device 220 has the air suction side 221 and the air exhaust side 222, in order to achieve the purpose of forming a negative pressure in the first region after the cleaner device 200 is docked with the dust collection station 100:

[0181] In an application, when the first region and the second region are kept in the isolation state or switched to the isolation state, the air suction side 221 of the air driving device 220 can be connected in communication with the first region (and at this time, the two are in the conduction state, which will not be described one by one below) to achieve the purpose of forming a negative pressure in the first region.

[0182] Or in an application, when the first region and the second region are kept in the conduction state or switched to the conduction state, the air suction side 221 of the air driving device 220 can also be connected in communication with the first region, or the air exhaust side 222 of the air driving device 220 can also be connected in communication with the second region to achieve the purpose of forming a negative pressure in the first region.

[0183] As known from the above, the negative pressure formed by the air driving device 220 in the first region and the second region can realize different operation requirements according to actual needs, for example, realizing the transfer of materials between the first region and the second region. Specifically, when the dust collection cavity is arranged in the dust collection station 100, and the dust storage cavity 212a is arranged in the dust collector device 200, the dust collection cavity constitutes the first region, and the dust storage cavity 212a defines the second region. At this time, when the air driving device 220 acts in the dust storage cavity 212a and generates a negative pressure in the dust storage cavity 212a, the negative pressure can be set to be able to suck and store the dirt in the external environment of the dust collector device 200 in the dust storage cavity 212a, and complete the dust collection operation. When the air driving device 220 acts in the dust collection cavity and generates a negative pressure in the dust collection cavity, if the dust collection cavity and the dust storage cavity 212a remain in a conductive state or switch to a conductive state, the negative pressure can be set to be able to collect the dirt in the dust storage cavity 212a into the dust collection cavity, and complete the dust extraction operation. In this way, only the air driving device 220 needs to be arranged on the dust collector device 200, and no other air driving device needs to be additionally arranged in the dust collection station 100. After the dust collector device 200 and the dust collection station 100 are docked, the air driving device 220 can be reused to realize the purpose of the dust extraction operation of transferring the dirt in the dust storage cavity 212a to the dust collection cavity, and has the characteristics of simplified overall structure, simple operation, and low maintenance cost.

[0184] DETAILED DESCRIPTION

[0185] 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 described in one or more of the above embodiments.

[0186] Specifically, the dust collector system includes a dust collection station 100 and a dust collector device 200, the dust collector device 200 including an air driving device 220; the dust collector system has a dust extraction state in which the dust collection station 100 and the dust collector device 200 are docked and at least partially conductive, and in the dust extraction state, the air driving device 220 acts in the dust collection station 100 to generate a negative pressure at least in the conductive region of the dust collection station 100.

[0187] In the design, when the dust collection station 100 is docked with the vacuum cleaner device 200, the partial areas (e.g. the first area and the second area in the above embodiment) of the vacuum cleaner system and the dust collection station 100 are in conduction (may be kept in conduction or switched to conduction), in the dust extraction state. The dust extraction state is a state in which the dust collection station 100 collects the dirt in the vacuum cleaner device 200, so that the dirt in the vacuum cleaner device 200 does not need to be separately emptied or cleaned, and the dust collection station 100 can uniformly collect and process the dirt, which can reduce the frequency of the user emptying the garbage. The vacuum cleaner system associates the dust extraction state with the air driving device 220 by pre-programming or manually triggering by the user, so that when in the dust extraction state, the air driving device 220 can generate negative pressure in at least the conduction area (e.g. the first area in the above embodiment) of the dust collection station 100.

[0188] It can be understood that in the dust extraction state, the conduction area (e.g. the first area) in the dust collection station 100 and the conduction area (e.g. the second area) in the vacuum cleaner device 200 are in conduction with each other, and the transfer of the material can be achieved. However, this does not constitute a limitation on the material transfer path, and according to actual needs, the material in the first area can be transferred to the second area or to other areas on the conduction path between the first area and the second area, or the material in the second area can be transferred to the first area or to other areas on the conduction path between the second area and the first area, or the material in other areas can be transferred to the first area and / or the second area, etc.

[0189] In a further scheme, when the dust collection cavity for dust collection is defined in the dust collection station 100, and the air driving device 220 has a suction side 221 and an exhaust side 222, in the dust extraction state, the suction side 221 is in communication with the dust collection cavity to provide negative pressure to the dust collection cavity. At this time, the dust collection cavity constitutes the conduction area of the dust collection station 100, and the dust collection cavity can directly transfer the dirt in the conduction area (e.g. the second area) of the vacuum cleaner device 200 to the dust collection cavity, or transfer the dirt in other areas (e.g. the external environment or other areas in the dust collection station 100) to the dust collection cavity, to achieve the purpose of collecting the dirt into the dust collection cavity.

[0190] Further, in an embodiment, when the dust storage cavity 212a is provided in the dust cleaner device 200, in the dust extraction state, the dust storage cavity 212a is communicated with the dust collection cavity, so that the dust-containing airflow in the dust storage cavity 212a enters the dust collection cavity under the negative pressure of the air driving device 220. In this way, the dirt in the dust storage cavity 212a can be transferred to the dust collection cavity, so that the dirt in the dust storage cavity 212a can be discharged in time, the space in the dust storage cavity 212a is released, and the dust cleaner device 200 can continue to perform the dust cleaning operation; and the dirt is concentrated in the dust collection cavity, which is especially helpful for storing the dirt transferred from the dust storage cavity 212a once or multiple times and facilitating subsequent concentrated treatment, reducing the number of concentrated treatments, and increasing the user experience.

[0191] At this time, the dust collection cavity and the dust storage cavity 212a can be directly communicated or indirectly communicated through, for example, a duct structure.

[0192] In the dust extraction state, the air driving device 220 drives the gas from the dust storage cavity 212a into the dust collection cavity to form a dust extraction airflow path. Optionally, the dust storage cavity 212a is arranged between the air exhaust side 222 of the air driving device 220 and the dust collection cavity, that is, the air exhaust side 222 is located upstream of the dust storage cavity 212a in the dust extraction airflow path, and the dust collection cavity is located downstream of the dust storage cavity 212a in the dust extraction airflow path, which is helpful for making the gas exhausted outward through the air exhaust side 222 first enter the dust storage cavity 212a and push the dirt in the dust storage cavity 212a into the dust collection cavity. Alternatively, the dust collection cavity is arranged between the dust storage cavity 212a and the air suction side 221, that is, the air suction side 221 is located downstream of the dust collection cavity in the dust extraction airflow path, and the dust storage cavity 212a is located upstream of the dust collection cavity in the dust extraction airflow path. This is helpful for making the external gas enter the dust storage cavity 212a under the suction of the air suction side 221 and suction the dirt in the dust storage cavity 212a into the dust collection cavity.

[0193] It should be noted that in the process of driving the gas from the dust storage cavity 212a into the dust collection cavity by the air driving device 220 to form the dust extraction airflow path, the source of the gas driven by the air driving device 220 can be directly the air inlet duct of the air inlet part 211. At this time, after the dust cleaner device 200 is docked with 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 kept in communication. Under the driving of the air driving device 220, the dust extraction airflow path is directly formed by the airflow sucked from the external environment by the air inlet part 211.

[0194] Alternatively, the source of the gas driven by the gas driving device 220 can be directly from a structure other than the air inlet duct of the air inlet portion 211. In an embodiment, the suction cleaner device 200 is provided with one or more auxiliary air inlets at any one or more positions on the air flow path between the dust storage chamber 212a and the air suction side 221 of the gas driving device 220. The auxiliary air inlets can be in communication with the external environment of the suction cleaner device 200. The auxiliary air inlets are provided as structures different from the air inlet duct of the air inlet portion 211. At this time, after the suction cleaner device 200 is docked with the dust collection station 100, under the driving of the gas 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 inlets.

[0195] Specifically, when a plurality of filter members are provided as described above, at least one auxiliary air inlet can be provided upstream of each filter member. In this way, in the dust extraction state, the air flow sucked into the suction cleaner device 200 via the auxiliary air inlets will sequentially pass through each filter member, thereby blowing off the dust and other contaminants remaining on each filter member, achieving cleaning of each filter member.

[0196] And / or, when a plurality of filter members are provided as described above, at least one auxiliary air inlet can be provided downstream of each filter member. In this way, in the dust extraction state, the air flow will also sequentially blow off the dust and other contaminants remaining on each filter member, achieving cleaning of each filter member.

[0197] In view of the above, when the gas driving device 220 and the local area in the dust collection station 100 are switched to the open state, the switching can be achieved by a preset switching device 230 in the suction cleaner system.

[0198] The switching device 230 has a first switching state in which the dust collection station 100 and the gas driving device 220 are open. It can be understood that in the first switching state, the gas driving device 220 and the local area in the dust collection station 100 are open, but at this time the gas driving device 220 and the local area in the suction cleaner device 200 can be open or isolated.

[0199] Specifically, when the dust collection station 100 is provided with a dust collection chamber, and the suction cleaner device 200 is provided with a dust storage chamber 212a, in the first switching state of the switching device 230, the gas driving device 220 and the dust collection chamber can be open, and the gas driving device 220 and the dust storage chamber 212a can be isolated, achieving the dust extraction operation described above.

[0200] Similarly, the switching device 230 also has a second switching state in which the dust collector device 200 and the air driving device 220 are connected. It can be understood that in the second switching state, the air driving device 220 and the local area in the dust collector device 200 are connected, but at this time the air driving device 220 and the local area in the dust collecting station 100 can be connected or isolated.

[0201] Specifically, when the dust collecting station 100 is provided with a dust collecting cavity, and the dust collector device 200 is provided with a dust storage cavity 212a, the switching device 230 in the second switching state can be configured to connect the air driving device 220 and the dust storage cavity 212a, and isolate the air driving device 220 and the dust collecting cavity, thereby realizing the above-mentioned dust collection operation.

[0202] There are many schemes for the switching device 230 to achieve the above-mentioned purpose:

[0203] In an application, the switching device 230 can be a component that directly acts on the air driving device 220:

[0204] For example, when the air driving device 220 is a mechanism that can interchange the air suction side 221 and the air exhaust side 222, the switching device 230 is configured 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 air suction side 221 of the air driving device 220 to be connected to the dust storage cavity 212a, the switching device 230 is in the second switching state; on the contrary, when the switching device 230 adjusts the air suction side 221 of the air driving device 220 to be connected to the dust collecting cavity, the switching device 230 is in the first switching state.

[0205] Alternatively, for example, the air driving device 220 is a mechanism that can be movably arranged relative to the dust storage cavity 212a and the dust collecting cavity, and the switching device 230 is configured 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 the air suction side 221 of the air driving device 220 is driven to be connected to the dust storage cavity 212a, and in the first switching state when the air suction side 221 of the air driving device 220 is driven to be connected to the dust collecting cavity.

[0206] In another application, the switching device 230 can also be an opening and closing structure that acts on a duct section (defined as the air suction duct 110 for ease of understanding) between the air driving device 220 and the dust collecting cavity, and / or acts on a duct section (i.e. the above-mentioned air exhaust duct 213a) between the air driving device 220 and the dust storage cavity 212a, and the opening and closing structure can be movably arranged to be able to move between the first switching state and the second switching device 230.

[0207] Correspondingly, the opening and closing structure can be used to guide the air outlet duct 213a and cut off the air inlet duct 110 (i.e. the switching device 230 has the second switching state alone); can be used to guide the air inlet duct 110 and cut off 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).

[0208] For example, the opening and closing structure can be switched between the first switching state and the second switching state:

[0209] In an application, the opening and closing structure can be provided with one opening and closing member. At this time, the air inlet duct 110 and the air outlet duct 213a are both arranged on the moving path of the opening and closing member, so that the opening and closing member can cut off the air inlet duct 110 and guide the air outlet duct 213a when moving close to the air inlet 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 cut off the air outlet duct 213a and guide the air inlet duct 110 when moving close to the air outlet duct 213a and moving away from the air inlet 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 inlet duct 110.

[0210] Or in another application, the opening and closing structure can be provided with at least two opening and closing members, which are the first opening and closing member 231 and the second opening and closing member 232. Among them, 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 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 duct 110), so as to have a second opening position and a second closing position; wherein when the first opening and closing member 231 moves to the first closing position and the second opening and closing member 232 moves to the second opening position, the first opening and closing member 231 cuts off the air outlet duct 213a and the second opening and closing member 232 guides the air inlet duct 110, and the switching device 230 is in the first switching state; when the first opening and closing member 231 moves to the first opening position and the second opening and closing member 232 moves to the second closing position, the first opening and closing member 231 guides the air outlet duct 213a and the second opening and closing member 232 cuts off the air inlet 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 duct 213a and the air inlet duct 110, so that the structure of the first opening and closing member 231 and the second opening and closing member 232 remains relatively independent.

[0211] Please refer to FIG. 1 to FIG. 8, and take the first opening and closing member 231 and the second opening and closing member 232 in the above description as examples:

[0212] 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.

[0213] 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 user manual operation, or respectively come from different mechanical mechanism driving implementation.

[0214] Or the movements of 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 movement time, movement path, movement direction, 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 is helpful to simplify the structure and operation of the whole machine.

[0215] It should be noted that the movement time described above 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 move at the same speed or at different speeds.

[0216] When the movements 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, and the linkage mechanism is connected to 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 to the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232.

[0217] In a further aspect, the linkage mechanism is configured to drive the first and second open-close members to move in the same direction during the process of opening the air outlet duct 213a or the air inlet duct 110. That is, when the first open-close member 231 moves to the first open position, the linkage mechanism drives the second open-close member 232 to move in the same direction to the second closed position; when the first open-close member 231 moves to the first closed position, the linkage mechanism drives the second open-close member 232 to move in the same direction to the second open position. The configuration of moving in the same direction helps to simplify the structural and spatial complexity of the movement of the first and second open-close members 231 and 232, and makes the first and second open-close members 231 and 232 keep a certain interval in the respective movement stroke as much as possible, and do not interfere with each other.

[0218] In view of the above, the driving source can be directly connected with one or more of the linkage mechanism, the first open-close member 231 and the second open-close member 232. Alternatively, in an embodiment, the switching device 230 further comprises a trigger member 234 connected with one or more of the linkage mechanism, the first open-close member 231 and the second open-close member 232, and the trigger member 234 is used to bear an external force (i.e. the driving source) to have a trigger stroke to drive the first and second open-close members 231 and 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 open-close member 231 to the first open position and the movement of the second open-close member 232 to the second closed position, or the stroke that can realize the movement of the first open-close member 231 to the first closed position and the movement of the second open-close member 232 to the second open 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 structural design constraints of the linkage mechanism, the first open-close member 231 and / or the second open-close member 232 can be reduced, the structural design freedom of the linkage mechanism, the first open-close member 231 and / or the second open-close member 232 can be increased, and good adaptation between the linkage mechanism, the first open-close member 231 and / or the second open-close member 232 and the driving source can be realized.

[0219] In view of 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 collection station 100, derived from the manual trigger of the user, or derived from the automatic trigger of the preset program and the like electric control devices.

[0220] For example, the trigger 234 can be arranged at the docking position of the cleaner 200 and the dust collecting station 100, and the trigger 234 can be actuated after the cleaner 200 and the dust collecting station 100 are docked. In this case, the actuation of the trigger 234 generally refers to the actuation of the first opening and closing member 231 to the first closed position and the second opening and closing member 232 to the second open position. In this way, the linkage of the first opening and closing member 231 and the second opening and closing member 232 can be automatically achieved after the cleaner 200 and the dust collecting station 100 are docked without the need of a dedicated electric control device or manual operation. Specifically, the first opening and closing member 231 can be actuated to the first closed position and the second opening and closing member 232 can be actuated to the second open position after the cleaner 200 and the dust collecting station 100 are docked. In this case, the trigger 234 can be arranged at the docking position of the cleaner 200 and the dust collecting station 100, and the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232 can be arranged in any orientation according to the actual installation environment.

[0221] In a further aspect, as shown in FIGS. 7 and 8, the first opening and closing member 231 and the second opening and closing member 232 can each have an installation end. The first opening and closing member 231 can be adapted to the cross-sectional shape of the air outlet duct 213a at the installation position and can be arranged in a plate shape or a column shape, etc. Similarly, the second opening and closing member 232 can be adapted to the cross-sectional shape of the air inlet duct 110 at the installation position and can be arranged in a plate shape or a column shape, etc. The linkage mechanism can include a first rotating shaft 233a rotatably arranged on the cleaner 200, and the installation ends of the first opening and closing member 231 and the second opening and closing member 232 can be non-rotatably arranged on the first rotating shaft 233a, so that the first opening and closing member 231 and the second opening and closing member 232 can be rotated in the same direction when the first rotating shaft 233a is rotated. The first opening and closing member 231 can reach the first open position and the first closed position during the rotation, and the second opening and closing member 232 can reach the second open position and the second closed position during the rotation. The trigger 234 can be connected to the first rotating shaft 233a, the first opening and closing member 231 and / or the second opening and closing member 232.

[0222] The mounting end of the first opening and closing member 231 and the mounting end of the second opening and closing member 232 are both rotationally mounted on the first rotating shaft 233a. For example, the first opening and closing member 231 and the first rotating shaft 233a can be integrally formed, or they can be fixedly connected after being separately formed. For example, as shown in FIGS. 7 and 8, the mounting end of the first opening and closing member 231 is sleeved on the outside of the first rotating shaft 233a, and the sleeve joint between them is non-circular, or one of the sleeve joints is provided with a rotation limiting protrusion, and the other is provided with a rotation limiting recess that matches the rotation limiting protrusion.

[0223] When the first opening and closing member 231 and the second opening and closing member 232 are both rotationally sleeved on the outside of the first rotating shaft 233a, the mounting end of the first opening and closing member 231 is provided with a sliding abutment with the outer circumferential wall of the first rotating shaft 233a or the mounting end of the second opening and closing member 232 at other positions except the sleeve joint on the first rotating shaft 233a. The second opening and closing member 232 is provided in the same way. In this way, there is no large gap between the first opening and closing member 231 and the first rotating shaft 233a, and between the second opening and closing member 232 and the first rotating shaft 233a, which achieves a certain dust and water prevention effect.

[0224] Further, the linkage mechanism further includes a second rotating shaft 233b, a first swing rod 233c, a second swing rod 233d, and a connecting rod 233e. The second rotating shaft 233b is rotationally mounted on the dust collector device 200 and extends in the same direction as the first rotating shaft 233a. One end of the first swing rod 233c is rotationally connected to the first rotating shaft 233a. One end of the second swing rod 233d is rotationally connected to the second rotating shaft 233b. The two ends of the connecting rod 233e are respectively rotationally connected to the other end of the first swing rod 233c and the other end of the second swing rod 233d. The trigger member 234 is connected to the first swing rod 233c, the second swing rod 233d, and / or the connecting rod 233e. 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 constitute a linkage mechanism. The first swing rod 233c and the first rotating shaft 233a, and the second swing rod 233d and the second rotating shaft 233b can be integrally formed or fixedly connected after being separately formed. The first swing rod 233c and the connecting rod 233e, and the second swing rod 233d and the connecting rod 233e are respectively hingedly connected, i.e., rotationally connected. When the trigger member 234 is triggered by an external force to perform a triggering stroke, it can drive the first swing rod 233c, the second swing rod 233d, and / or the connecting rod 233e, and then make the linkage mechanism operate, and finally achieve the purpose of driving the first opening and closing member 231 and the second opening and closing member 232 to operate.

[0225] Specifically, as shown in FIGS. 7-8, 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, finally driving the first opening and closing member 231 and the second opening and closing member 232 to rotate in the same direction.

[0226] 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 lever 233c, the second swing lever 233d, and the connecting rod 233e. Under the driving of the external force, the trigger 234 performs a triggering stroke, and drives the first opening and closing member 231 to block the air outlet air duct 213a (i.e., to move to the first closed position) and the second opening and closing member 232 to conduct the air outlet air duct 213a (i.e., to move 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 conduct the air outlet air duct 213a (i.e., to move to the first open position) and the second opening and closing member 232 to block the air inlet air duct 110 (i.e., to move to the second closed position), at this time, the switching device 230 is in the second switching state.

[0227] 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 protrudes 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 suction side 221 of the air driving 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 conducts the air inlet air duct 110, the first opening and closing member 231 can be tightly fitted with the first stop protrusion under the suction force of the air suction side 221 of the air driving device 220, thereby increasing the blocking effect of the first opening and closing member 231 on the air outlet air duct 213a.

[0228] 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 protrudes 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 driving 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 conducts 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 suction force of the air suction side 221 of the air driving device 220, thereby increasing the blocking effect of the second opening and closing member 232 on the air outlet air duct 213a.

[0229] In addition, in combination with FIGS. 9-19, the disclosure further provides another embodiment of the switching device 230:

[0230] Specifically, referring to FIGS. 9-19, the switching device includes a wind guide part 300 and an opening and closing part 400. The wind guide part 300 forms a wind guide channel 310 provided with two connection ports for communicating with external channels. The opening and closing part 400 is movably arranged in the wind guide channel 310 to have a switching state of moving to cover one connection port and open the other connection port. In the switching state, the opening and closing part 400 defines at least two flow passages communicated with the open connection port.

[0231] In the technical solution provided by the disclosure, the wind guide channel 310 formed by the wind guide part 300 can be adapted to communicate with at least two external channels, and under the movement 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 is movable in the wind guide channel 310, which can utilize the internal space of the wind guide channel 310, so that the installation and movement of the opening and closing part 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 part 400 defines at least two flow passages communicated with the open connection port in the switching state, the air flowing into or out of the external channel connected by the open connection port can be subjected to targeted operations such as flow splitting, flow reversing, flow adjusting, etc., thereby making the switching device have 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 to be more versatile and reliable.

[0232] It should be noted that in the above and below embodiments, although the channel structure is not necessarily limited to a channel structure with a circular cross-sectional shape in the transverse direction, the channel structure is generally defined to have an axial direction, a radial direction and a circumferential direction for ease of understanding.

[0233] The opening and closing part 400 is movably arranged in the wind guide channel 310, and in the movement stroke of the opening and closing part 400, it has a switching state of moving to open one connection port and cover the other connection port. Then when the two connection ports are the first connection port 321 and the second connection port 331 as described above:

[0234] The opening and closing part 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 channel between the dust storage cavity 212a and the air driving device 220 is communicated and the channel between the dust collection cavity and the air driving device 220 is blocked, and the dust collector device 200 can independently perform the dust collection operation based on the channel between the dust storage cavity 212a and the air driving device 220.

[0235] 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 connecting port 321 and open the second connecting port 331. In the first switching state, the passage between the dust storage cavity 212a and the air driving device 220 is blocked and the passage between the dust collection cavity and the air driving device 220 is opened, so that the dust collection station 100 can perform dust extraction based on the passage between the dust collection cavity 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.

[0236] In actual application, the switching device can be provided with the second switching state or the first switching state. 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 covered; 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 covered.

[0237] Of course, the switching device can also have both the second switching state and the first switching state, in which case, in the movement of the opening and closing part 400, the switching device can be switched between the second switching state and the first switching state. For ease of understanding, the following will be described with reference to the switching device being provided with both the second switching state and the first switching state.

[0238] It can be understood that the movement of the opening and closing part 400 can switch between the second switching state and the first switching state, and can 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.

[0239] When the first connection port 321 is opened, the dust storage cavity 212a and the air guide passage 310 of the cleaner device 200 are communicated. The flow channels are generally arranged at the downstream side of the first connection port 321. At this time, the flow channels form at least independent multiple flow paths. The gas from the same source (e.g. the dust storage cavity 212a) passing through the first connection port 321 can flow in the flow channels alternatively or synchronously. When the flow conditions (e.g. flow direction, flow rate, etc.) of the flow channels are the same, the flow channels can play the role of shunting; and each flow channel can be an alternative of any flow channel, so that when any flow channel is blocked or abnormal, at least the remaining flow channels can be selected, and the downstream side flow communication function of the first connection port 321 fails. Or when the flow conditions (e.g. flow direction, flow rate, etc.) of the flow channels 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.

[0240] In a further aspect, the air guide passage 310 is provided with a mounting hole 340 in the side wall at the preset passage section, the mounting hole 340 is communicated with the air driving device 220, and the mounting hole 340 is specifically communicated with the air suction side of the air driving device 220. In this way, whether the first connection port 321 is opened or the second connection 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 cleaner system is more compact in structure, and the manufacturing and maintenance costs are reduced.

[0241] Based on one or more of the above embodiments, further, regarding the specific arrangement of the opening and closing part 400:

[0242] It can be understood that the specific structure, activity form, activity direction, etc. of the opening and closing part 400 can be adjusted according to the specific arrangement of the first connection port 321 and the second connection port 331.

[0243] For example, when the first connection port 321 and the second connection port 331 are both arranged on the same channel side wall of the air guide channel 310 and are arranged in axial direction of the air guide channel 310, in an embodiment, the opening and closing part 400 can be arranged to be movable in the axial direction of the air guide channel 310, so as to be able to move to be close to the first connection port 321 and away from the second connection port 331, and to be away from the first connection port 321 and close to the second connection port 331, so as to realize the active switching between the second switching state and the first switching state. Alternatively, in an embodiment, the opening and closing part 400 can be arranged to be rotatably connected to the channel wall between the first connection port 321 and the second connection port 331, and is substantially in the shape of a lever, so that when a segment of the opening and closing part 400 rotates towards the first connection port 321, another segment of the opening and closing part 400 is driven to rotate away from the second connection port 331; when a segment of the opening and closing part 400 rotates towards the second connection port 331, another segment of the opening and closing part 400 is driven to rotate away from the first connection port 321, so as to also realize the active switching between the second switching state and the first switching state.

[0244] Alternatively, for example, when the first connection port 321 and the second connection port 331 are arranged on the two side walls in the radial direction of the air guide channel 310 and are arranged in the radial direction of the air guide channel 310, the opening and closing part 400 can be arranged to be reciprocally movable between the two connection ports, and in the switching state, the opening and closing part 400 abuts against the side wall where the connection port to be closed is located, and is spaced apart from the side wall where the connection port to be opened is located, so as to define at least two flow channels at the spacing respectively. For example, when 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 of the air guide channel 310, 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 being open at the location, 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 being open at the location, and constitutes at least two flow channels.

[0245] When the first connecting port 321 is connected with the dust storage cavity 212a in the cleaner device 200, and the second connecting port 331 is connected with the dust collecting cavity in the dust collecting station 100 after the cleaner device 200 and the dust collecting station 100 are docked, for example, when the cleaner device 200 is not docked with the dust collecting station 100, i.e. the cleaner device 200 is independently operated, the opening and closing part 400 is maintained in the second switching state, i.e. the opening and closing part 400 covers the second connecting port 331 and opens the first connecting 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 cleaner device 200 and the dust collecting 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, i.e. the opening and closing part 400 covers the first connecting port 321 and opens the second connecting port 331, so that the channel between the dust collecting cavity and the air driving device 220 is open.

[0246] In the above, the triggering structure can be arranged at the docking position of the cleaner device 200 and the dust collecting station 100, and the triggering structure is triggered by the docking action of the cleaner device 200 and the dust collecting station 100. Or the triggering structure can be electrically connected with the sensor device and the control device, and then the control device controls the triggering structure to drive the opening and closing part 400 to move after receiving the sensing signal of the sensor device.

[0247] Then, the switching movement of the opening and closing part 400 between the second switching state and the first switching state can be directly realized by the triggering structure or the preset program. Or in an embodiment, the triggering 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 can be driven to reset from the first switching state to the second switching state by, for example, an elastic component 500. Based on this, in an embodiment, the switching device further comprises an elastic component 500 connected between the opening and closing part 400 and the air guiding part 300; under the driving of external force, the opening and closing part 400 is driven by the external force to move from one connecting port to another connecting port; when the external force is removed, the opening and closing part 400 is driven to reset by the elastic component 500. The elastic component 500 is, for example, a spring piece, a metal spring piece, a rubber or silicone piece, etc.

[0248] The specific structure of the opening and closing part 400 is not limited, which can be but is not limited to a plate, a block, a column, etc. Please combine FIG. 13 and FIG. 19. In an embodiment, the opening and closing part 400 includes 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 along the direction of the connection line between the first connection port 321 and the second connection port 331, that is, the first radial extension described above. The two body segments divided by the ring-shaped step 420 of the opening and closing body 410 are defined as the first body segment 411 facing the first connection port 321 and the second body segment 412 facing the second connection port 331 for easy understanding; the step surface of the ring-shaped step 420 facing the first connection port 321 is defined as the first step surface 421, and the step surface facing the second connection port 331 is defined as the second step surface 422.

[0249] At this time, taking the second switching state as an example:

[0250] The way in which the opening and closing part 400 covers the second connection port 331 can be that the second body segment 412 is inserted at the second connection port 331 to realize one-time sealing and covering of the second connection port 331 by the opening and closing part 400; and the second step surface 422 abuts against the second channel side wall 330 to realize two-time sealing and covering of the second connection port 331 by the opening and closing part 400.

[0251] And the way in which the opening and closing part 400 opens the first connection port 321 can be:

[0252] In an embodiment, in the switching state, one body segment is separated from being arranged outside one connection port, and the corresponding side step surface of the ring-shaped 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 body segment 411 can be completely separated from outside the first connection port 321 and be in the air guide channel 310. Similarly, the first step surface 421 of the ring-shaped step 420 is also completely separated from the first channel side wall 320, and at this time, the first connection port 321 is not shielded and is in an open state.

[0253] Or in an embodiment, in the switching state, a main body section is inserted into a connecting port, and the inserted connection of both is formed with a gap, the gap is communicated between 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, but because the outer diameter of the first main body section 411 is smaller than the hole diameter of the first connecting port 321, a gap is formed between the outer wall of the first main body section 411 and the hole wall of the first connecting 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 200 can flow into the air guide channel 310 through the gap after entering the first connecting port 321, realizing the conduction of the first connecting port 321 and the air guide channel 310.

[0254] 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 that conducts 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 and the hole diameter of the first connecting port 321 are at least equivalent at the first connecting port 321. At this time, the switching device is integrally provided with the connecting channel 430, and the connecting channel 430 at least extends from the first connecting port 321 to the air guide channel 310, realizing the conduction of the first connecting port 321 and the air guide channel 310.

[0255] Further, taking the connecting channel 430 provided above as an example:

[0256] Please refer to Fig. 13, the connection channel 430 can be formed in the inside of the switching device, and its lateral side is substantially closed, having a first channel opening 431 penetrating to the first 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 connection port, the switching device is arranged with gradually decreasing outer diameter at least in 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 connection port 321. The outer diameter of the switching device at least in the part where the first channel opening 431 is opened, that is, the first body section 411, is arranged with gradually increasing outer diameter in the direction close to the first connection port 321, forming an inclined outer peripheral side wall. In this way, on the one hand, the first body section 411 can be adapted to the different hole diameters of the first connection port 321 by the gradually increasing outer diameter to achieve targeted plugging; on the other hand, the first channel opening 431 can be opened on the inclined outer peripheral side wall, having a larger opening area.

[0257] Please refer to Fig. 19, the connection channel 430 can also be opened on the outer peripheral side wall of the switching device, and the connection channel 430 is arranged with an open mouth penetrating the side wall of the switching device, being substantially in the form of a slot. At this time, the connection channel 430 can guide the first connection port 321 and the air guide channel 310 through the open mouth.

[0258] 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 in a detachable or non-detachable manner after being formed in a separate body. 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 body section and / or the annular step 420 can be made of elastic material, or directly mounted with an elastic layer.

[0259] 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, and the adapting part 600 is formed with a mounting channel 610 in communication with a connection port and extending in the same direction; the switching device further comprises a mounting part 700 connected to one end of the body section away from the annular step 420 and accommodated in the mounting channel 610. As shown in Figs. 10 to 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 movably.

[0260] The mounting portion 700 and the opening and closing portion 400 can be integrally formed, or can be connected after being separately formed, and the connection can be detachable or non-detachable. Regardless of whether the opening and closing portion 400 is in the second switching state or in the first switching state, the mounting portion 700 is always accommodated in the mounting channel 610, and thus, it is helpful to assist the opening and closing portion 400 to be more stably mounted and more smoothly moved.

[0261] In a further aspect, one of the inner wall of the mounting channel 610 and the outer wall of the mounting portion 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 portion 700 from being pulled out of the mounting channel 610. Similarly, in order to achieve flexible abutment between the inner wall of the mounting channel 610 and the outer wall of the mounting portion 700, the inner wall of the mounting channel 610 and / or the outer wall of the mounting portion 700 can be made of elastic material or directly mounted with an elastic layer.

[0262] In addition, in an embodiment, the adapter portion 600 is further provided with an extension channel 620 in the side wall of the mounting channel 610, the extension channel 620 extends at least to one radial side or one axial side of the mounting channel 610, and is used to adaptively connect with the external channel of the carrier product on which the switching device is mounted. The adapter portion 600 can adaptively mount between the air guide portion 300 and the carrier product (such as the dust collector 200) as a whole; and the extension channel 620 can adaptively connect the dust storage cavity 212a and / or the pre-filter 243 of the dust collector 200 with the first connection port 321.

[0263] In the above embodiment, the adapter portion 600 and the air guide portion 300 are integrally formed, or the adapter portion 600 and the air guide portion 300 are separately formed and then connected, and the connection can be detachable or non-detachable. It should be noted that the above does not limit the number of structures of the air guide portion 300 and / or the adapter portion 600. For example, as shown in FIG. 12, in order to better mount the opening and closing portion 400, the air guide portion 300 can be separately formed with the adapter portion 600, and the air guide portion 300 itself can be detachably connected by two shell structures, and when the two are connected, the air guide portion 300 and the adapter portion 600 together define the guide air duct. Alternatively, as shown in FIG. 18, the air guide portion 300 and the adapter portion 600 are at least partially integrally formed, and similarly, in order to better mount the opening and closing portion 400, the air guide portion 300 and the adapter portion 600 as a whole can be detachably connected by two shell structures, and when the two are connected, the air guide portion 300 and the adapter portion 600 together define the guide air duct.

[0264] When the connecting passage 430 is provided as described above, the connecting passage 430 can be opened only at the first body section 411 or extended and opened between the first 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 connecting passage 430 extending between the mounting portion 700 and the adjacent body section, and the connecting passage 430 is in communication with the air guiding passage 310 and the mounting passage 610 when the connecting port in communication with the mounting passage 610 is opened.

[0265] In view of the above, the air guiding passage 310 is provided in a ring shape. When in the switching state (for example, the second switching state), the opening and closing portion 400 maintains the air guiding passage 310 in communication along the circumferential direction thereof at least at the opened connecting port (for example, the first connecting port 321), so as to define at least two flow channels in communication with the opened connecting port. At this time, the air flow entering the air guiding passage 310 through the first connecting port 321 can flow along one side of the air guiding passage 310 at the location, forming one flow channel, or flow along the other side of the air guiding passage 310 at the location, forming another flow channel.

[0266] Since the downstream end of the flow channel is not limited to converge together, that is, the extension length of the flow channel in the air guiding passage 310 is not limited, the flow channel can be formed in a partial passage section of the air guiding passage 310, and at this time, the opening and closing portion 400 maintains the partial passage section in communication along the circumferential direction thereof. Or the flow channel can be formed in the entire air guiding passage 310, and at this time, the opening and closing portion 400 maintains the entire air guiding passage 310 in communication along the circumferential direction thereof.

[0267] 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, when the air guide passage 310 is in communication with the air driving device 220, in a further solution, 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, and on the other hand makes 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 center axis of the dust collector device 200, the disturbance caused by the flow of the gas in each flow channel is more balanced or directly counteracted, avoiding the situation that the dust collector device 200 has greater disturbance and noise on one side, and reducing the user experience.

[0268] In addition to the air driving device 220 as described above, the dust collector device 200 further comprises 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.

[0269] 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 is 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.

[0270] 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.

[0271] 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 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.

[0272] 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 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 to make room for the connection port and / or the mounting passage 610 extending through the extending passage 620.

[0273] 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 cylinder 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 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 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.

[0274] Specific implementation 3:

[0275] 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 described in one or more of the above embodiments.

[0276] The dust collector system comprises a dust collector device 200, a dust collecting station 100 and a switching device 230. The dust collector device 200 comprises a holding portion and an air driving device 220; the dust collecting station 100 is used to dock the dust collector device 200, and the dust collecting station 100 is internally provided with a dust collecting cavity for dust collection; after the dust collector device 200 is docked with the dust collecting station 100, the switching device 230 can selectively conduct the air driving device 220 and the dust collecting cavity. In the design, the switching device 230 is used to selectively conduct or cut off the air driving device 220 and the dust collecting cavity.

[0277] Further, in an embodiment, a dust collecting air duct independently working is formed in the dust collector device 200; after the dust collector device 200 is docked with the dust collecting station 100, the dust collector system further forms a dust extracting air duct, the dust extracting air duct is provided with the dust collecting cavity, the dust extracting air duct is used to transfer the dirt collected by the dust collector device 200 into the dust collecting cavity, and the switching device 230 is used to selectively conduct the dust collecting air duct or the dust extracting air duct. When the switching device 230 conducts the dust collecting air duct, the dust collecting air duct can independently perform dust collection under the action of the air driving device 220 or without the action of the air driving device 220. When the switching device 230 conducts the dust extracting air duct, the switching device 230 can conduct the air driving device 220 and the dust collecting cavity, and can transfer the dirt collected by the dust collector device 200 into the dust collecting cavity. It should be noted that the dirt collected by the dust collector device 200 is not limited to be stored in the dust collecting air duct, but can also be stored in other areas except the dust collecting air duct.

[0278] Further, when the switching device 230 has a first switching state and a second switching state, the first switching state can be specifically defined as that the dust collecting air duct is conducted; and / or the second switching state can be specifically defined as that the dust extracting air duct is conducted.

[0279] Specifically, in an embodiment, the dust collector 200 comprises an air inlet part 211 and a dust storage part 212, and a dust storage cavity 212a for storing dirt is formed in the dust storage part 212; the air inlet part 211 and the dust storage part 212 can be of the structure in the above embodiment or other structure design. The dust suction air duct is in sequence communicated with the air inlet part 211, the dust storage cavity 212a and the air driving device 220, so that when the dust suction air duct is conducted by the switching device 230, the flow path between the air inlet duct, the dust storage cavity 212a and the air driving device 220 is conducted, the external dirt can be brought into the air inlet duct by the gas and trapped in the dust storage cavity 212a, and the relatively clean gas is discharged outwardly through the exhaust side 222 of the air driving device 220. Wherein, when the air outlet part 213 is also included as described above, the external dirt can be brought into the air inlet duct by the gas and trapped in the dust storage cavity 212a, the relatively clean gas flows through the air outlet duct 213a, and finally is discharged outwardly through the exhaust side 222 of the air driving device 220, completing the dust suction operation. And / or, the dust extraction air duct is in sequence communicated with the dust storage cavity 212a, the dust collection cavity and the air driving device 220, so that when the dust extraction air duct is conducted by the switching device 230, the flow path between the dust storage cavity 212a, the dust collection cavity and the air driving device 220 is conducted, the dirt in the dust storage cavity 212a can enter the dust collection cavity under the driving of the air driving device 220, completing the dust extraction operation.

[0280] In addition, in an embodiment, the dust collector 200 further comprises a pre-filter 243 located downstream of the dust storage cavity 212a and upstream of the air driving device 220, and the dust suction air duct passes through the pre-filter 243, that is, the gas entering the suction side 221 of the air driving device 220 through the dust suction air duct will pass through the pre-filter 243 again before entering the air driving device 220, which helps to ensure that the gas entering the air driving device 220 is relatively clean, avoiding that part of the dirt in the dust storage cavity 212a is brought into the air driving device 220, causing the suction side 221 or the exhaust side 222 of the air driving device 220 to be blocked. The dust extraction air duct does not pass through the pre-filter 243. That is, the pre-filter 243 is not arranged between the dust collection cavity and the suction side 221 of the air driving device 220, avoiding that the pre-filter 243 affects the dust extraction effect.

[0281] In an embodiment, the dust extraction air duct has an air duct outlet 215c communicated with the dust collector 200 and the dust collection station 100, and the air duct outlet 215c is close to the pre-filter 243, which helps to make the structure of the whole machine compact.

[0282] In addition, in an embodiment, the dust extraction air duct includes a connecting air duct 214 connecting the pre-filter 243 and the air driving device 220, and at least part of the connecting air duct 214 is arranged at the periphery of the pre-filter 243. It can be understood that the air duct between the downstream of the dust storage chamber 212a and the upstream of the air driving device 220 is an air outlet air duct 213a. When the pre-filter 243 is close to the downstream of the dust storage chamber 212a, the connecting air duct 214 is substantially the air outlet air duct 213a. When the pre-filter 243 is spaced apart from the downstream of the dust storage chamber 212a, the pre-filter 243 divides the air outlet air 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 at 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.

[0283] Further, the connecting air duct 214 can be arranged to be snail-shaped along the periphery of the pre-filter 243. The snail-shaped can specifically refer to a single-ring annular shape, or can refer to a multi-ring annular shape. Among them, 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.

[0284] In addition, the following is a specific embodiment of the switching device 230:

[0285] The dust collector device 200 is provided with a dust storage chamber 212a for storing dirt and an air outlet air duct 213a connecting the dust storage chamber 212a and the air driving device 220, and the dust collector system is provided with a suction air duct 110 connecting the air driving device 220 and the dust collection station 100, and the switching device 230 includes an opening and closing structure, which selectively opens the air outlet air duct 213a and blocks the suction air duct 110, or opens the suction air duct 110 and blocks the air outlet air duct 213a.

[0286] The dust collector device 200 is provided with a dust storage chamber 212a for storing dirt and an air outlet air duct 213a connecting the dust storage chamber 212a and the air driving device 220, and the switching device 230 includes a first opening and closing member 231, which is movably mounted in the air outlet air duct 213a to movably open and block the air outlet air duct 213a.

[0288] The dust cleaner device 200 is provided with a dirt storage cavity 212a for storing dirt, and an air outlet duct 213a connecting the dirt storage cavity 212a and the air driving device 220. The dust cleaner system is provided with an air suction duct 110 connecting the air driving device 220 and the dust collecting station 100. The switching device 230 comprises a first opening and closing member 231 and a second opening and closing member 232. The first opening and closing member 231 is movably installed at the air outlet duct 213a, so as to movably open and close the air outlet duct 213a. The second opening and closing member 232 is movably installed in the air suction duct 110, so as to movably open and close the air suction duct 110. When the first opening and closing member 231 opens the air outlet duct 213a, the second opening and closing member 232 closes the air suction duct 110. When the first opening and closing member 231 closes the air outlet duct 213a, the second opening and closing member 232 opens the air suction duct 110.

[0289] The first opening and closing member 231 and the second opening and closing member 232 are movably arranged independently of each other.

[0290] The first opening and closing member 231 and the second opening and closing member 232 are movably arranged independently of each other.

[0291] The first opening and closing member 231 and the second opening and closing member 232 are movably arranged independently of each other.

[0298] Specific Implementation 4:

[0299] 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.

[0300] The dust collector system comprises a dust collection station 100 and a dust collector device 200. The dust collection station 100 is provided with a dust collection chamber. The dust collector device 200 comprises a housing, a gas driving device 220, and a switching device 230. The housing is provided with a dust suction duct, and a dust storage chamber 212a is defined in the dust suction duct. The gas driving device 220 is arranged in the housing and has an air suction side 221 in communication with the dust suction duct. The switching device 230 forms a dust extraction duct between the air suction side 221, the dust storage chamber 212a, and the dust collection chamber after the dust collector device 200 is docked with the dust collection station 100. The switching device 230 can selectively conduct the dust suction duct and the dust extraction duct, and when the dust extraction duct is conducted, the gas driving device 220 generates a negative pressure in the dust collection chamber.

[0301] In the present design, when the switching device 230 is switched on, the air suction channel is in operation, and the air driving device 220 can be used to suck the dirt and directly trap the dirt in the dust storage chamber 212a, thus completing the air suction operation. When the dust collector device 200 is connected to the dust collection station 100, the air suction side 221, the dust storage chamber 212a and the dust collection chamber are connected and switched on by the switching device 230, so that the dirt in the dust storage chamber 212a can be transferred to the dust collection chamber, thus completing the dust extraction operation.

[0302] Further, in an embodiment, after the dust collector device 200 is connected to the dust collection station 100, the switching device 230 can selectively switch on or cut off the air channel section between the dust storage chamber 212a and the dust collection chamber in the dust extraction air channel. In this way, the user can operate the switching device 230 to switch on the dust storage chamber 212a and the dust collection chamber to enable the dust extraction operation, or switch off the dust storage chamber 212a and the dust collection chamber to disable the dust extraction operation, but can still form a negative pressure in the dust collection chamber to perform operations such as compressing the dirt in the dust collection chamber, transferring dirt from other areas to the dust collection chamber, and the like.

[0303] In an embodiment, after the dust collector device 200 is connected to the dust collection station 100, the switching device 230 can selectively switch on or cut off the air channel section between the air suction side 221 and the dust collection chamber in the dust extraction air channel. In this way, the user can operate the switching device 230 to selectively form a negative pressure in the dust collection chamber through the air suction side 221, which is particularly helpful in preventing the air suction side 221 from interfering with the environment in the dust collection chamber in application scenarios where a negative pressure is not needed in the dust collection chamber.

[0304] In relation to the description in the above embodiment 2, the air driving device 220 can be movably arranged, and the switching device 230 can directly act on the air driving device 220 to drive the air driving device 220 to move, so that the air suction side 221 can be moved to be in communication with the dust storage chamber 212a and the dust collection chamber, respectively.

[0305] Alternatively, in an embodiment, the dust suction air channel and the dust extraction air channel share a partial air channel section to form a shared air channel section 215a, and the air suction side 221 is arranged at the shared air channel section 215a; the dust extraction air channel has a remaining dust extraction section 111a except the shared air channel section 215a, and the dust suction air channel has a remaining dust suction section 215b except the shared air channel section 215a, and the switching device 230 is movably arranged at the remaining dust suction section 215b and the remaining dust extraction section 111a.

[0306] It can be understood that, referring to the description in the above embodiment 2-3, the section of the dust suction air duct between the dust storage cavity 212a and the air suction side 221 is the air outlet duct 213a, and the section of the dust suction air duct between the pre-filter 243 and the air suction side 221 is the connecting air duct 214. Taking the connecting air duct 214 as an example, the remaining dust suction section 111a can be connected to the side wall of the connecting air duct 214, and the connection between the two constitutes the air duct outlet 215c, which directly divides the connecting air duct 214 into the common air duct section 215a connected to the air suction side 221 and the remaining dust suction section 215b connected to the downstream of the pre-filter 243. The common air duct section 215a and the remaining dust suction section 111a jointly constitute the whole or part of the dust suction air duct. The switching device 230 is movably arranged in the remaining dust suction section 215b and the remaining dust suction section 111a, which can respectively and independently realize the opening and closing control of the remaining dust suction section 215b and the remaining dust suction section 111a, and can reduce the interference to the air suction side 221.

[0307] Next, in an embodiment, the dust collector device 200 further comprises at least one filter, each filter being arranged in the dust suction air duct in sequence; wherein the common air duct section 215a is formed on the air outlet side of the at least one filter. In this way, the gas flowing through the dust suction air duct to the common air duct section 215a can pass through the at least one filter, which is relatively cleaner, and can avoid the occurrence of large solid residues that block the common air duct section 215a, resulting in the dust suction air duct and the dust suction air duct being unable to be switched on by the switching device 230.

[0308] Further, in an embodiment, the dust collector device 200 further comprises at least one filter, each filter being arranged in the dust suction air duct in sequence; wherein the common air duct section 215a is formed on the air outlet side of all the filters. In this way, the gas flowing through the dust suction air duct to the common air duct section 215a can pass through all the filters, which can more effectively avoid the occurrence of large solid residues that block the common air duct section 215a, resulting in the dust suction air duct and the dust suction air duct being unable to be switched on by the switching device 230.

[0309] Further, when the filter closest to the air suction side 221 among the filters is the pre-filter 243 as described above, the pre-filter 243 is arranged in a cylindrical shape, and the section of the dust suction air duct on the air outlet side of the pre-filter 243 (i.e., the connecting air duct 214) is arranged in a snail shape along the outer periphery of the pre-filter 243. The common air duct section 215a is formed on the downstream section of the connecting air duct 214.

When the first opening and closing member 231 opens the remaining suction section 215b, the second opening and closing member 232 closes the remaining dust extraction section 111a. When the first opening and closing member 231 closes the remaining suction section 215b, the second opening and closing member 232 opens the remaining dust extraction section 111a.

[0316] The trigger member 234 is arranged at the interface between the dust collector device 200 and the dust collection station 100. The dust collector device 200 drives the trigger member 234 to perform the trigger stroke after being connected with the dust collection station 100.

[0317] The first opening and closing member 231 and the second opening and closing member 232 each have a mounting end. The linkage mechanism comprises a first rotating shaft 233a which is rotatably installed in the casing.

Under the action of an external force, the trigger 234 performs a triggering stroke and drives the first opening and closing member 231 to block the remaining dust suction section 215b and the second opening and closing member 232 to open the remaining dust suction section 111a. When the external force is removed, the elastic reset member 233f drives the first opening and closing member 231 to return to open the remaining dust suction section 215b and the second opening and closing member 232 to block the remaining dust suction section 111a.

[0331] DETAILED DESCRIPTION 6

[0332] Referring to FIGS. 1-12, 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.

[0333] The dust collector system includes a dust collection station 100 and a dust collector device 200. The dust collection station 100 is provided with a dust collection cavity. The dust collector device 200 includes a holding portion, an air driving device 220, and a switching device 230. The dust collector device 200 is provided with a dust suction air duct, and a dust storage cavity 212a is defined in the dust suction air duct. The air driving device 220 has a suction side 221 in communication with the dust suction air duct. After the dust collector device 200 and the dust collection station 100 are docked, the switching device 230 forms a dust extraction air duct between the suction side 221, the dust storage cavity 212a, and the dust collection cavity. The switching device 230 can selectively open and close the dust suction air duct and the dust extraction air duct, and when the dust extraction air duct is opened, the air driving device 220 generates a negative pressure in the dust collection cavity.

[0334] In the present design, when the switching device 230 opens the dust suction air duct, the air driving device 220 can act on the dust suction air duct to suck and directly trap dirt in the dust storage cavity 212a, thereby completing the dust suction operation. When the dust collector device 200 and the dust collection station 100 are docked, the suction side 221, the dust storage cavity 212a, and the dust collection cavity are connected in communication, and can be switched by the switching device 230 to be opened, so that the dirt in the dust storage cavity 212a can be transferred to the dust collection cavity, thereby completing the dust extraction operation.

[0335] Further, in an embodiment, after the dust collector device 200 and the dust collection station 100 are docked, the switching device 230 can selectively open or block the air duct section between the dust storage cavity 212a and the dust collection cavity in the dust extraction air duct. In this way, the user can operate the switching device 230 to enable the dust extraction operation when the dust storage cavity 212a and the dust collection cavity are opened, and vice versa, to disable the dust extraction operation, but can complete operations such as compression of dirt in the dust collection cavity, transfer of dirt from other areas to the dust collection cavity, and the like by forming a negative pressure in the dust collection cavity.

[0336] In an embodiment, after the dust cleaner device 200 is docked with the dust collecting station 100, the switching device 230 can selectively open or close the air duct section between the air suction side 221 and the dust collecting cavity in the dust extraction air duct section. In this way, the user can selectively form a negative pressure in the dust collecting cavity through the air suction side 221 by operating the switching device 230 according to actual needs, which is especially helpful in preventing the air suction side 221 from interfering with the environment in the dust collecting cavity in application scenarios where it is not necessary to form a negative pressure in the dust collecting cavity.

Taking the connecting air duct 214 as an example, at this time, specifically, the remaining dust extraction section 111a can be connected to the side wall of the connecting air duct 214, and the connection between them constitutes an air duct outlet 215c, which directly divides the connecting air duct 214 into the shared air duct section 215a connected to the air suction side 221 and the remaining dust suction section 215b connected to the downstream of the pre-filter 243. The shared air duct section 215a and the remaining dust extraction section 111a together constitute the entire or partial dust extraction air duct. The switching device 230 is movably arranged at the remaining dust suction section 215b and the remaining dust extraction section 111a, which can respectively and independently achieve the opening and closing control of the remaining dust suction section 215b and the remaining dust extraction section 111a, and can reduce the interference with the air suction side 221.

In this way, the gas flowing through the dust suction air duct to the common air duct section 215a can pass through the at least one filter, and the relatively cleaner gas can avoid causing the common air duct section 215a to be blocked by large solid residues, so that the dust suction air duct and the dust extraction air duct cannot be switched on by the switching device 230.
