[0145] A dust storage chamber 212a is formed within the dust storage section 212. The downstream portion of the air inlet duct can be connected to the upstream portion of the dust storage chamber 212a. The dust storage section 212 can be configured as a columnar structure extending in the vertical direction. In this case, the air inlet section 211 can be generally arranged on one side of the dust storage section 212 in the horizontal direction, and the air inlet section 211 and the air inlet duct formed therein can be generally arranged to extend in the horizontal direction.

[0146] An air outlet duct 213a is generally formed inside the air outlet portion 213, and the upstream of the air outlet duct 213a is connected to the downstream of the dust storage chamber 212a. The downstream of the air outlet portion 213 can generally directly constitute the air outlet of the entire machine, so that after the dust storage portion 212 intercepts the dirt in the gas carrying dirt in the dust storage chamber 212a, the air outlet portion 213 can discharge the relatively clean gas to the outside through the air outlet.

[0147] The grip portion is the portion that the user holds to drive the entire device. There is no restriction on its specific structure, and it can be, but is not limited to, a rod or a ring.

[0148] like Figures 1 to 3 As shown, in order to make the structure of the whole machine compact, the dust storage part 212 and the air outlet part 213 can be configured to extend in a columnar shape along the vertical 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 in the horizontal direction, and the grip part is arranged on the other side of the dust storage part 212 in the horizontal direction.

[0149] In view of the above, the vacuum cleaner device 200 can at least be used for dust collection. In order to achieve the purpose of gas entering the air inlet duct from the air inlet, passing through the dust storage part 212 and the air outlet part 213, and finally being discharged outward from the air outlet, in a specific application, the vacuum cleaner device 200 also includes an air purging device 220. The air purging 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 component (such as a fan) alone, or a combination of at least two single components (such as a fan and an air guide structure). The air purging device 220 can, for example, include a fan, which can be but is not limited to an axial flow fan, a cross-flow fan, a centrifugal fan, etc. The air purging device 220 generally has a suction side 221221 and an exhaust side 222222 under normal operating conditions. When started, the suction side 221221 of the degassing device 220 forms a negative pressure, which can draw the external air flow into the degassing device 220; the exhaust side 222222 forms a positive pressure, which can discharge the air flow inside the degassing device 220 to the outside.

[0150] In actual application, the exhaust side 222222 of the air purging device 220 can be connected to the air inlet to blow gas into the air inlet duct, so as to achieve the purpose of driving the gas from the air inlet into the air inlet duct, passing through the dust storage chamber 212a and the air outlet duct 213a, and finally being discharged outward from the air outlet. However, in order to reduce the adverse effect of the setting of the air purging device 220 on the air flow of the air inlet part 211, in the following example, Figures 1 to 19 In the illustrated embodiments, the suction side 221221 of the air purging device 220 is connected to the downstream of the air outlet duct 213a, and the exhaust side 222222 of the air purging device 220 constitutes the air outlet of the whole machine. In addition, in order to achieve the purpose of retaining the dirt carried in the external air connected to the air inlet 211 in the dust storage chamber 212a, in a specific application, the vacuum cleaner device 200 may also include at least one filter element, which is at least arranged in the dust storage chamber 212a and may also be arranged in the air outlet duct 213a. There is no limitation on the number of filters, the specific type, etc., for example Figure 3 As shown, the filter element may be, but is not limited to, one or more of a first filter element 241, a second filter element 242, and a pre-filter 243. The first filter element 241 may be a porous filter arranged in a cylindrical shape, the second filter element 242 may be a multi-cone filter, and both the first filter element 241 and the second filter element 242 are arranged in the upstream section of the dust storage chamber 212a. The pre-filter 243 is arranged in a roughly cylindrical shape in the downstream section of the dust storage chamber 212a, for example, specifically at the connection point between the dust storage chamber 212a and the air outlet duct 213a, or directly at the air outlet duct 213a. Generally, the structure formed by the dust storage portion 212 and at least one filter element is what is commonly referred to as a dust cup assembly.

[0151] In addition, in order to realize the orderly operation of each component in the vacuum cleaner system, the vacuum cleaner system may further include a power supply device 800 and a control device. The power supply device 800 may include but is not limited to a one-time charge and discharge power supply device, such as a disposable battery; or the power supply device 800 may also include a repeatedly charge and discharge power supply device, such as a 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 purging device 220 facing away from the air outlet 213 / dust storage section 212. The control device can at least be electrically connected to the power supply device 800 and the air purging device 220, so as to be able to control the charging and discharging of the power supply device 800, and control the air purging device 220 to start, stop, and adjust the preset operating power and other operations according to actual needs, such as according to a preset program or in response to a user's trigger instruction. The control device can be built into the vacuum cleaner device 200, or can be externally located at, for example, the dust collection station 100 or other locations according to actual needs, and can communicate with the exhaust device 220 on the vacuum cleaner device 200 through, for example, a wireless connection. Figure 3 As shown, the power supply device 800 can be arranged on a side of the air purging device 220 away from the air inlet portion 211 and opposite to the air inlet portion 211 .

[0152] In addition, the vacuum cleaner device 200 and / or the dust collection station 100 may also be provided with a display module and / or an input device. The display module includes a display panel, which may display digitally or graphically as needed. The input device may be, but is not limited to, physical or virtual buttons, a voice recognition module, a gesture recognition module, etc., allowing the user to manually enter relevant trigger commands.

[0153] Of course, depending on actual needs, the vacuum cleaner device 200 and / or the dust collection station 100 may also be equipped with one or more sensor devices. The sensor device is electrically connected to the control device so that the control device can intelligently control the operation of the corresponding functional components based on the sensing data of the sensor device. The sensor device can, for example, be located at the interface between the vacuum cleaner device 200 and the dust collection station 100, and be triggered and generate a sensor signal when the vacuum cleaner device 200 and the dust collection station 100 are docked.

[0154] In view of any one or more of the above embodiments of the vacuum cleaner device 200, the dust collection station 100 is generally a product used in conjunction with the vacuum cleaner device 200. The vacuum cleaner device 200 has a first operating state in which it operates independently from the dust collection station 100, and a second operating state in which it is docked with the dust collection station 100. When in the second operating state, the dust collection station 100 can perform various preset operations on the vacuum cleaner device 200 under the drive of a preset program or in response to a user trigger command. The preset operations may include, but are not limited to, charging, cleaning, vacuuming, and other operations.

[0155] In view of one or several embodiments of the vacuum cleaner system described above, in order to overcome the disadvantages of the prior art that a dust collection station 100 motor needs to be specially set up, resulting in a complex structure of the entire system and high maintenance costs, several specific implementation methods will be provided below in conjunction with the accompanying drawings for illustration. Specific implementation 1:

[0157] See also Figures 1 to 19 The present invention provides a vacuum cleaner system, which may be but is not limited to the vacuum cleaner system in one or more of the above embodiments.

[0158] Specifically, the vacuum cleaner system includes a dust collecting station 100 and a vacuum cleaner device 200, the vacuum cleaner device 200 includes a gripping portion and an air expelling device 220; after the vacuum cleaner device 200 is docked with the dust collecting station 100, the air expelling device 220 acts inside the dust collecting station 100 to generate negative pressure in at least a partial area inside the dust collecting station 100.

[0159] In this design, after the vacuum cleaner device 200 is docked with the dust collecting station 100, the dust collecting station 100 can reasonably utilize the air expelling device 220 fixed on the vacuum cleaner device 200 to generate negative pressure in at least part of the area within the dust collecting station 100, thereby facilitating the dust collecting station 100 to utilize the negative pressure generated in this area to perform operations such as dust extraction, dirt compression, and dust discharge. The dust collecting station 100 does not need to be additionally equipped with structures such as fans, so that the overall structure of the dust collecting station 100 can be simpler and lighter, and the overall maintenance cost of the dust collecting station 100 is lower.

[0160] It should be noted that, in the following embodiments:

[0161] The purge device 220 is generally pre-integrated in the housing of the vacuum cleaner device 200, which contributes to the compactness of the structure. However, it can be understood that the above does not constitute a limitation on the application of the purge device 220 when the vacuum cleaner device 200 is in the first working state. According to actual needs, when the vacuum cleaner device 200 is in the first working state, the purge device 220 can be in a stopped state on the vacuum cleaner device 200, that is, it is not applied to any area in the vacuum cleaner device 200. Alternatively, a second area is defined in the vacuum cleaner device 200, and when the vacuum cleaner device 200 is in the first working state, the purge device 220 acts on the second area, and can form positive pressure or negative pressure in the second area.

[0162] Based on this, the specific form of expression of the second area is not limited. For example, when, as described above, the air purging device 220 is used to drive the gas into the air inlet duct through the air inlet, and flows through the dust storage chamber 212a and the air outlet duct 213a, and is finally discharged outward from the air outlet, the second area can specifically refer to the air inlet duct, the dust storage chamber 212a and the air outlet duct 213a as a whole. For example, when the air purging device 220 is used to compress the dirt already in the dust storage chamber 212a, the second area can refer to the dust storage chamber 212a. For example, when the air purging device 220 is used to clean the dirt remaining on each filter element, the second area can refer to the chamber in the vacuum cleaner device 200 that accommodates each filter element. No further details will be given.

[0163] After the vacuum cleaner device 200 and the dust collection station 100 are docked, the purge device 220 acts on at least a partial area within the dust collection station 100. Specifically, a first area is defined within the dust collection station 100, and after the vacuum cleaner device 200 and the dust collection station 100 are docked, the purge device 220 acts on at least the first area and forms a negative pressure within the first area.

[0164] Among them, after the vacuum cleaner device 200 and the dust collecting station 100 are docked, it refers to after the vacuum cleaner device 200 and the dust collecting station 100 start the docking action. Therefore, the timing of the air purging device 220 acting in the first area is not limited, and can be associated with the docking action of the vacuum cleaner device 200 and the dust collecting station 100. The time point of its triggering is at the same time when the vacuum cleaner device 200 and the dust collecting station 100 start the docking action, or at the same time when the two complete the docking action, or within a certain period of time after the two complete the docking action, etc. The triggering method of the air purging device 220 acting in the first area is also not limited. It can be directly triggered by the docking action of the vacuum cleaner device 200 and the dust collecting station 100, or triggered by manual operation of the user, or automatically triggered by preset program control (the control device executes independently, or the control device and the sensor device cooperate to execute), etc.

[0165] After the vacuum cleaner device 200 and the dust collecting station 100 are docked, the air purging device 220 can selectively connect or isolate the suction side 221 from the first area. It can be understood that after the vacuum cleaner device 200 and the dust collecting station 100 are docked, the suction side 221 of the air purging device 220 can be structurally connected to the first area directly or indirectly through the air duct structure, but whether the connection between the two is in a conductive state or in a disconnected state can be manually selected by the user or automatically by the program. When the user manually or the program automatically controls the suction side 221 of the air purging device 220 to connect with the first area, the suction side 221 of the air purging device 220 directly acts on the first area and forms a negative pressure in the first area; when the user manually or the program automatically controls the suction side 221 of the air purging device 220 to isolate the first area, the suction side 221 of the air purging device 220 may not currently act on the first area. There are many ways to switch between the on state and the off state, which will be explained below in conjunction with specific embodiments and will not be described in detail here.

[0166] Furthermore, when a first region and a second region are provided:

[0167] In one application, the first area can be isolated from the second area. At this time, the first area uses the negative pressure generated by the purge device 220 to perform its own required operations. Its operations are, for example, compressing the materials in the first area, transferring the materials in the first area, or transferring the materials in other areas except the second area to the first area, etc. However, it should be noted that at this time, it is not limited whether the purge device 220 acts on the second area at the same time. According to actual needs, the purge device 220 may not act on the second area, or may act on the second area at the same time and form positive pressure or negative pressure in the second area.

[0168] Of course, in another application, the first region may also be electrically connected to the second region. The purge device 220 generates negative pressure at least in the first region. It should be noted that the purge device 220 is not necessarily required to act on the second region. However, since the first and second regions are electrically connected, the negative pressure in the first region may have a greater or lesser impact on the air pressure in the second region. This air pressure effect can be used, as in the following embodiments, to transfer material from the second region to the first region, or it may not involve material transfer.

[0169] In view of the above, it is important to emphasize that, at least after the vacuum cleaner device 200 and the dust collection station 100 are docked, the first and second areas may remain in a blocked state and cannot be switched to a conductive state; or the first and second areas may remain in a conductive state and cannot be switched to a blocked state; or the first and second areas may switch between a blocked state and a conductive state at will. Similarly, the switching between the blocked state and the conductive state may be manually triggered by the user or electronically triggered by a program or other means.

[0170] Similarly, when the first area and the second area are provided as described above, and the purge device 220 has a suction side 221 and an exhaust side 222, in order to achieve the purpose of forming a negative pressure in the first area after the vacuum cleaner device 200 is docked with the dust collection station 100:

[0171] In one application, if the first area and the second area remain in a partitioned state or are switched to a partitioned state, the purpose of forming a negative pressure in the first area can be achieved by connecting the suction side 221 of the air venting device 220 to the first area (and at this time the two are in a conductive state, which will not be described in detail below).

[0172] Or in one application, if the first area and the second area remain in a conductive state or are switched to a conductive state, the purpose of forming a negative pressure in the first area can also be achieved by connecting the suction side 221 of the air expelling device 220 to the first area, or by connecting the exhaust side 222 of the air expelling device 220 to the second area.

[0173] In view of the above, it can be seen that the negative pressure formed by the purge device 220 in the first area and the second area can achieve different operational requirements according to actual needs, such as realizing material transfer between the first area and the second area. Specifically, when a dust collecting chamber is provided in the dust collection station 100 and a dust storage chamber 212a is provided in the dust collector device 200, the dust collecting chamber constitutes the first area, and the dust storage chamber 212a defines the second area. At this time, when the purge device 220 acts on the dust storage chamber 212a and generates a negative pressure in the dust storage chamber 212a, it can be set so that the negative pressure can suck the dirt in the external environment of the vacuum cleaner device 200 and store it in the dust storage chamber 212a, completing the dust collection operation. When the purge device 220 acts on the dust collecting chamber and generates a negative pressure in the dust collecting chamber, if the dust collecting chamber and the dust storage chamber 212a remain in a conductive state or switch to a conductive state, it can be set so that the negative pressure can collect the dirt in the dust storage chamber 212a into the dust collecting chamber, completing the dust collection operation. In this way, it is only necessary to set up the air purge device 220 on the vacuum cleaner device 200, and there is no need to set up other air purge devices in the dust collecting station 100. After the vacuum cleaner device 200 and the dust collecting station 100 are docked, the air purge device 220 can be reused to achieve the purpose of dust extraction operation by transferring the dirt in the dust storage chamber 212a to the dust collecting chamber. It has the characteristics of simplified overall structure, simple operation and low maintenance cost. Specific implementation 2:

[0175] See also Figures 1 to 19 The present invention provides a vacuum cleaner system, which may be but is not limited to the vacuum cleaner system described in one or more of the above embodiments.

[0176] Specifically, the vacuum cleaner system includes a dust collecting station 100 and a vacuum cleaner device 200, the vacuum cleaner device 200 includes a gripping portion and an air expelling device 220; the vacuum cleaner system has a dust extraction state in which the dust collecting station 100 and the vacuum cleaner device 200 are docked and at least a local area is conductive. In the dust extraction state, the air expelling device 220 acts inside the dust collecting station 100 to generate negative pressure at least in the conductive area inside the dust collecting station 100.

[0177] In this design, after the dust collecting station 100 is docked with the vacuum cleaner device 200, the vacuum cleaner system and the local area of ​​the dust collecting station 100 (such as the first area and the second area in the above embodiment) are connected (can be kept in the conductive state or switched to the conductive state) and are in the dust extraction state. The dust extraction state is also the state in which the dust collecting station 100 collects the dirt in the vacuum cleaner device 200 in a centralized manner, so that the dirt in the vacuum cleaner device 200 does not need to be dumped or cleaned separately, and is centrally processed by the dust collecting station 100, which can reduce the number of times the user takes out the trash. The vacuum cleaner system associates the dust extraction state with the purging device 220 by pre-programming or manually triggering it by the user, so that when it is in the dust extraction state, the purging device 220 can generate negative pressure at least in the conductive area (such as the first area in the above embodiment) in the dust collecting station 100.

[0178] It is understood that in the dust extraction state, the conductive area (e.g., the first area) within the dust collection station 100 and the conductive area (e.g., the second area) within the vacuum cleaner device 200 are connected to each other, thereby enabling the transfer of materials. However, this does not constitute a limitation on the material transfer path. Depending on actual needs, materials in the first area can be transferred to the second area or to other areas on the conductive path between the first and second areas. Materials in the second area can also be transferred to the first area or to other areas on the conductive path between the second and first areas. Materials in other areas can also be transferred to the first area and / or the second area, etc.

[0179] In a further embodiment, when a dust collecting chamber for collecting dust is defined in the dust collecting station 100, and the air purging device 220 has a suction side 221 and an exhaust side 222, in the dust extraction state, the suction side 221 is connected to the dust collecting chamber to provide negative pressure to the dust collecting chamber. At this time, the dust collecting chamber also constitutes the conductive area of ​​the dust collecting station 100 described above, and the dust collecting chamber can directly transfer dirt in the conductive area (such as the second area) in the vacuum cleaner device 200 to the dust collecting chamber, or transfer dirt in other areas (such as the external environment or other areas in the dust collecting station 100) to the dust collecting chamber, thereby achieving the purpose of collecting dirt in the dust collecting chamber.

[0180] Furthermore, in one embodiment, when a dust storage chamber 212a for storing dust is provided in the vacuum cleaner device 200, in the dust extraction state, the dust collection chamber is connected to the dust storage chamber 212a, so that the dust-laden airflow in the dust storage chamber 212a enters the dust collection chamber under the negative pressure of the air purging device 220. In this way, the purpose of transferring the dirt in the dust storage chamber 212a to the dust collection chamber is achieved, so that the dirt in the dust storage chamber 212a can be discharged in a timely manner, freeing up space in the dust storage chamber 212a, and facilitating the vacuum cleaner device 200 to continue the vacuuming operation; the dirt is also concentrated in the dust collection chamber, especially when sufficient space is reserved in the dust collection chamber. This helps to store dirt transferred from the dust storage chamber 212a once or multiple times, facilitating subsequent centralized processing, reducing the number of centralized processing times, and improving the user experience.

[0181] At this time, the dust collecting chamber and the dust storage chamber 212a can be directly connected, or can be indirectly connected through, for example, an air duct structure.

[0182] In the dust extraction state, the air purging device 220 drives the gas from the dust storage chamber 212a into the dust collecting chamber to form a dust extraction airflow path: optionally, the dust storage chamber 212a is set between the exhaust side 222 of the air purging device 220 and the dust collecting chamber, that is, the exhaust side 222 is located upstream of the dust storage chamber 212a on the dust extraction airflow path, and the dust collecting chamber is located downstream of the dust storage chamber 212a on the dust extraction airflow path, which helps to make the gas discharged outward through the exhaust side 222 first enter the dust storage chamber 212a and push the dirt in the dust storage chamber 212a into the dust collecting chamber. Or optionally, the dust collecting chamber is located between the dust storage chamber 212a and the suction side 221, that is, the suction side 221 is located downstream of the dust collecting chamber on the dust extraction airflow path, and the dust storage chamber 212a is located upstream of the dust collecting chamber on the dust extraction airflow path. This helps to allow external air to enter the dust storage chamber 212a under the suction action of the suction side 221, and to suck the dirt in the dust storage chamber 212a into the dust collecting chamber.

[0183] It should be noted that, in the process of the purge device 220 driving the gas from the dust storage chamber 212a into the dust collecting chamber to form the dust extraction airflow path, the source of the gas driven by the purge device 220 can be directly from the air inlet duct of the air inlet portion 211. At this time, after the vacuum cleaner device 200 is docked with the dust collecting station 100, the air inlet duct of the air inlet portion 211, the dust storage chamber 212a of the dust storage portion 212, and the dust collecting chamber of the dust collecting station 100 remain connected. Driven by the purge device 220, the dust extraction airflow path is directly formed by the flow of air sucked from the external environment by the air inlet portion 211.

[0184] Alternatively, the source of the gas driven by the air purging device 220 may be directly from other structures other than the air inlet duct of the air inlet portion 211. In one embodiment, the vacuum cleaner device 200 is provided with one or more auxiliary air inlets at any one position or several positions on the air flow path between the dust storage chamber 212a and the suction side 221 of the air purging device 220. The auxiliary air inlet may be connected to the external environment of the vacuum cleaner device 200. And the auxiliary air inlet is configured to have a different structure from the air inlet duct of the air inlet portion 211. At this time, after the vacuum cleaner device 200 is docked with the dust collecting station 100, under the drive of the air purging device 220, the dust extraction air flow path is directly formed by the flow of air sucked from the external environment by the auxiliary air inlet.

[0185] Specifically, when multiple filters are provided as described above, at least one auxiliary air inlet can be provided upstream of each filter. Thus, during vacuuming, air drawn into the vacuum cleaner 200 via the auxiliary air inlet passes through each filter in sequence, blowing off dust and other contaminants remaining on each filter, thereby cleaning each filter.

[0186] And / or, when multiple filter elements are provided as described above, at least one auxiliary air inlet may be provided downstream of each filter element. In this way, during dust extraction, the airflow will also blow away dust and other impurities remaining on each filter element, thereby cleaning each filter element.

[0187] In view of the above, when the purge device 220 and the local area in the dust collection station 100 are switched to a conductive state, the switching can be achieved by operating the switching device 230 preset in the vacuum cleaner system.

[0188] The switching device 230 has a first switching state that connects the dust collection station 100 and the purge device 220. It is understood that in the first switching state, the purge device 220 is connected to the local area in the dust collection station 100, but at this time, the purge device 220 and the local area in the vacuum cleaner device 200 can be connected or isolated.

[0189] Specifically, when a dust collecting chamber is provided in the dust collecting station 100 and a dust storage chamber 212a is provided in the vacuum cleaner device 200, the switching device 230 can be set in the first switching state to connect the air purging device 220 and the dust collecting chamber, and to separate the air purging device 220 and the dust storage chamber 212a, so as to realize the above-mentioned dust extraction operation.

[0190] Similarly, the switching device 230 also has a second switching state for connecting the vacuum cleaner device 200 and the purging device 220. It is understood that in the second switching state, the purging device 220 and the local area within the vacuum cleaner device 200 are connected, but at this time, the purging device 220 and the local area within the dust collection station 100 can be connected or isolated.

[0191] Specifically, when a dust collecting chamber is provided in the dust collecting station 100 and a dust storage chamber 212a is provided in the vacuum cleaner device 200, the switching device 230 can be set in the second switching state to connect the air purging device 220 and the dust storage chamber 212a, and to separate the air purging device 220 and the dust collecting chamber, so as to realize the above-mentioned dust collection operation.

[0192] There are various solutions for the switching device 230 to achieve the above purpose:

[0193] In one application, the switching device 230 may be a component that directly acts on the purge device 220:

[0194] For example, when the purge device 220 is a mechanism capable of interchanging its suction side 221 and exhaust side 222, the switching device 230 is configured as a component capable of controlling the purge device 220 to perform the interchanging operation. In this case, when the switching device 230 adjusts the suction side 221 of the purge device 220 to be in communication with the dust storage chamber 212a, the switching device 230 is in the second switching state; conversely, when the switching device 230 adjusts the suction side 221 of the purge device 220 to be in communication with the dust collection chamber, the switching device 230 is in the first switching state.

[0195] Alternatively, for example, when the purge device 220 is a mechanism that is movably disposed relative to the dust storage chamber 212a and the dust collection chamber, the switching device 230 is configured as a component that can drive the purge device 220 to perform translational or rotational movement. In this case, the switching device 230 can be in the second switching state when the suction side 221 of the purge device 220 is driven to be in communication with the dust storage chamber 212a; and can be in the first switching state when the suction side 221 of the purge device 220 is driven to be in communication with the dust collection chamber.

[0196] In another application, the switching device 230 can also be an opening and closing structure that acts on the air duct section between the air purging device 220 and the dust collecting chamber (for ease of understanding, this air duct section is defined as the suction duct 110), and / or acts on the air duct section between the air purging device 220 and the dust storage chamber 212a (that is, the above-mentioned air outlet duct 213a). The opening and closing structure can be movably arranged to be able to flexibly switch between the first switching state and the second switching device 230.

[0197] Corresponding to the above, the opening and closing structure can be used alone to conduct the outlet air duct 213a and block the suction air duct 110 (that is, the switching device 230 alone has the second switching state); it can also be used alone to conduct the suction air duct 110 and block the outlet air duct 213a (that is, the switching device 230 alone has the first switching state); or it can switch between the above-mentioned first switching state and the second switching state (that is, the switching device 230 has both the first switching state and the second switching state).

[0198] Take the example of an opening and closing structure that can switch between a first switching state and a second switching state:

[0199] In one application, the opening and closing structure can be configured to include an opening and closing member. In this case, the suction duct 110 and the outlet duct 213a are both arranged on the movable path of the opening and closing member, so that when the opening and closing member moves closer to the suction duct 110 and away from the outlet duct 213a, it can block the suction duct 110 and connect the outlet duct 213a (at this time, the switching device 230 is in the second switching state), and when it moves closer to the outlet duct 213a and away from the suction duct 110, it can block the outlet duct 213a and connect the suction duct 110 (at this time, the switching device 230 is in the first switching state). This helps to simplify the opening and closing structure, but it imposes certain restrictions on the structural design of the outlet duct 213a and the suction duct 110.

[0200] Or in another application, the opening and closing structure can be configured to include at least two opening and closing members, the two opening and closing members being a first opening and closing member 231 and a second opening and closing member 232. The first opening and closing member 231 can be movably arranged between the degassing device 220 and the dust storage chamber 212a (i.e., movably arranged at the air outlet duct 213a) to have a first open position and a first closed position; the second opening and closing member 232 can be movably arranged between the degassing device 220 and the dust collection station 100 (i.e., movably arranged at the air suction duct 110) to have a second open position and a second closed position; When the opening and closing member 232 moves to the second open position, the first opening and closing member 231 blocks the outlet air duct 213a and the second opening and closing member 232 connects to the suction air 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 open position and the second opening and closing member 232 moves to the second closed position, the first opening and closing member 231 connects to the outlet air duct 213a and the second opening and closing member 232 blocks the suction air duct 110, and the switching device 230 is in the second switching state. This helps reduce the constraints on the structural design of the outlet air duct 213a and the suction air duct 110, allowing the structures of the first opening and closing member 231 and the second opening and closing member 232 to remain relatively independent.

[0201] See also Figures 1 to 8 Specifically, take the first opening and closing member 231 and the second opening and closing member 232 as an example:

[0202] It can be understood that the first opening and closing member 231 and the second opening and closing member 232 each independently form their own movement mode. For example, the first opening and closing member 231 can be selectively set to perform translational movement and / or rotational movement, and the second opening and closing member 232 can also be selectively set to perform translational movement and / or rotational movement.

[0203] At this time, the first opening and closing member 231 and the second opening and closing member 232 can move independently of each other, that is, the movement timing, movement path, movement direction, driving method, etc. of the first opening and closing member 231 are not affected by the second opening and closing member 232; vice versa, the movement timing, movement path, driving method, 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 each be equipped with a driving source, which can be manually operated by the user or driven by different mechanical mechanisms.

[0204] Alternatively, the first opening and closing member 231 and the second opening and closing member 232 may move in a coordinated manner, that is, the first opening and closing member 231 and the second opening and closing member 232 may mutually influence each other in at least one of their movement timing, movement path, movement direction, and driving method. The first opening and closing member 231 and the second opening and closing member 232 may be equipped with the same driving source, which helps simplify the structure and operation of the entire device.

[0205] It should be noted that the above-mentioned activity timing includes whether the first opening and closing member 231 and the second opening and closing member 232 are started at the same time or one after another; it also includes whether the first opening and closing member 231 and the second opening and closing member 232 are moved at the same speed or at a differential speed.

[0206] When the first opening and closing member 231 and the second opening and closing member 232 are moved in a coordinated manner as described above, in a specific application, the switching device 230 further includes a linkage mechanism that links the first opening and closing member 231 and the second opening and closing member 232. In this case, the driving source can be connected to one or more of the linkage mechanism, the first opening and closing member 231, and the second opening and closing member 232.

[0207] In a further embodiment, the linkage mechanism is configured to drive the first opening and closing member 231 and the second opening and closing member 232 to move in the same direction during the process of conducting the air outlet duct 213a or the air intake duct 110. That is, when the first opening and closing member 231 moves to the first open position, the linkage mechanism drives the second opening and closing member 232 to move in the same direction to the second closed position; when the first opening and closing member 231 moves to the first closed position, the linkage structure drives the second opening and closing member 232 to move in the same direction to the second open position. The setting of the same-direction movement helps to simplify the structural and spatial complexity of the movement of the first opening and closing member 231 and the second opening and closing member 232, and enables the first opening and closing member 231 and the second opening and closing member 232 to maintain a certain distance as much as possible during their respective movement strokes without interfering with each other.

[0208] In view of the above, the driving source can be directly connected to the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232 for driving. Or in one embodiment, the switching device 230 further includes a trigger member 234, which is connected to the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232 for driving, and the trigger member 234 is used to withstand the action of an external force (i.e., the driving source) so as to have a trigger stroke that drives the first opening and closing member 231 and the second opening and closing member 232 to move in the same direction under the drive of the external force. The trigger stroke can refer to a stroke that can realize the first opening and closing member 231 to move to the first open position and the second opening and closing member 232 to move to the second closed position, or it can refer to a stroke that can realize the first opening and closing member 231 to move to the first closed position and the second opening and closing member 232 to move 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 constraints on the structural design of the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 can be reduced, and the structural design freedom of the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 can be increased, thereby achieving good adaptation between the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 and the driving source.

[0209] In view of the above, the specific scheme of the driving source is not limited. It can be derived from the docking action of the vacuum cleaner device 200 and the dust collection station 100, from the manual triggering of the user, or from the automatic triggering of electronic control devices such as preset programs.

[0210] Taking the docking action in which the driving source comes from the vacuum cleaner device 200 and the dust collecting station 100 as an example, the trigger member 234 can be set at the docking point of the vacuum cleaner device 200 and the dust collecting station 100. After the vacuum cleaner device 200 and the dust collecting station 100 are docked, the trigger member 234 is driven to perform the above-mentioned trigger stroke. At this time, the trigger stroke generally refers to the stroke that can realize the first opening and closing member 231 to move to the first closed position and the second opening and closing member 232 to move to the second open position. In this way, there is no need to specially set up an electric control period, and there is no need for manual operation by the user. The linkage of the first opening and closing member 231 and the second opening and closing member 232 can be automatically realized after the vacuum cleaner device 200 and the dust collecting station 100 are docked. Specifically, when the vacuum cleaner device 200 and the dust collecting station 100 are docked, the first opening and closing member 231 is moved to the first closed position and the second opening and closing member 232 is moved to the second open position. At this time, the trigger member 234 is set at the joint of the vacuum cleaner device 200 and the dust collection station 100, while the setting orientation of the linkage mechanism, the first opening and closing member 231 and the second opening and closing member 232 is relatively free and can be set according to the actual installation environment.

[0211] In further solutions, please combine Figures 7 and 8 , the first opening and closing member 231 and the second opening and closing member 232 each have a mounting end. The first opening and closing member 231 can be adapted to the cross-sectional shape of the air outlet duct 213a at its location and set to a plate or column, etc.; similarly, the second opening and closing member 232 can be adapted to the cross-sectional shape of the air suction duct 110 at its location and set to a plate or column, etc. The linkage mechanism includes a first rotating shaft 233a, which is rotatably mounted on the vacuum cleaner device 200. The mounting ends of the first opening and closing member 231 and the second opening and closing member 232 are both fixedly mounted on the first rotating shaft 233a, so that when the first rotating shaft 233a rotates, the first opening and closing member 231 and the second opening and closing member 232 are respectively driven to rotate in the same direction. The first opening and closing member 231 can reach a first open position and a first closed position during its rotation; the second opening and closing member 232 can reach a second open position and a second closed position during its rotation. The triggering member 234 is connected to the first rotating shaft 233 a , the first opening and closing member 231 and / or the second opening and closing member 232 .

[0212] The implementation method of the first opening and closing member 231 and the second opening and closing member 232 being fixed on the first rotating shaft 233a is not limited. Taking the first opening and closing member 231 and the first rotating shaft 233a as an example, the first opening and closing member 231 and the first rotating shaft 233a can be integrally formed, or they can be separately formed and then fixedly connected detachably or non-detachably. Figures 7 and 8For example, the detachable fixed connection is such that 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 the two is set to a non-circular shape, or one of the sleeve joints is provided with a stop protrusion, and the other is provided with a stop concave portion that is adapted to the stop protrusion.

[0213] When both the first opening and closing member 231 and the second opening and closing member 232 are non-rotatably sleeved on the outside of the first rotating shaft 233a, the mounting end of the first opening and closing member 231, except for the portion that is sleeved on the first rotating shaft 233a, is configured to slide against the outer peripheral sidewall of the first rotating shaft 233a at the corresponding position, or against the mounting end of the second opening and closing member 232 at the corresponding position. The second opening and closing member 232 is configured similarly. This ensures that there is no significant gap between the first opening and closing member 231 and the first rotating shaft 233a, or between the second opening and closing member 232 and the first rotating shaft 233a, thereby achieving a certain degree of dust and water resistance.

[0214] Furthermore, the linkage mechanism also includes a second rotating shaft 233b, a first swing arm 233c, a second swing arm 233d, and a connecting rod 233e. The second rotating shaft 233b is rotatably mounted on the vacuum cleaner device 200 and extends in the same direction as the first rotating shaft 233a and is spaced apart therefrom. One end of the first swing arm 233c is fixedly connected to the first rotating shaft 233a. One end of the second swing arm 233d is fixedly connected to the second rotating shaft 233b. The ends of the connecting rod 233e are respectively rotatably connected to the other ends of the first swing arm 233c and the other ends of the second swing arm 233d. The trigger member 234 is connected to the first swing arm 233c, the second swing arm 233d, and / or the connecting rod 233e. The first rotating shaft 233a, the second rotating shaft 233b, the first swing arm 233c, the second swing arm 233d, and the connecting rod 233e constitute the connecting rod 233e mechanism. Similar to the above, the first swing arm 233c and the first rotating shaft 233a, and the second swing arm 233d and the second rotating shaft 233b can be integrally formed, or they can be separately formed and then removably or non-removably connected. The first swing arm 233c and the connecting rod 233e, and the second swing arm 233d and the connecting rod 233e are each movably hinged, that is, rotationally connected. When the trigger member 234 is triggered by an external force to perform the trigger stroke, it can drive the first swing arm 233c, the second swing arm 233d, and / or the connecting rod 233e, thereby causing the connecting rod 233e mechanism to operate in conjunction, ultimately achieving the purpose of driving the first opening and closing member 231 and the second opening and closing member 232 in conjunction.

[0215] Specifically Figures 7 and 8For example, the trigger member 234 is connected to the second rotating shaft 233b for rotation. When the trigger member 234 is triggered by an external force, it drives the second rotating shaft 233b to rotate, the second rocker arm 233d to swing, the connecting rod 233e to move, the first rocker arm 233c to swing, and the first rotating shaft 233a to rotate, and finally drives the first opening and closing member 231 and the second opening and closing member 232 to rotate in the same direction.

[0216] In view of the above, further, the linkage mechanism further includes an elastic return member 233f, one end of the elastic return member 233f is connected to the vacuum cleaner device 200, and the other end is connected to at least one of the first opening and closing member 231, the second opening and closing member 232, the first rotating shaft 233a, the second rotating shaft 233b, the first swing rod 233c, the second swing rod 233d and the connecting rod 233e; under the drive of external force, the trigger member 234 performs a trigger stroke and drives the first opening and closing member 231 to block the air outlet duct 213a (also That is, it moves to the first closed position) and the second opening and closing member 232 connects the air outlet duct 213a (that is, it moves to the second open position). At this time, the switching device 230 is in the first switching state; when the external force is removed, the elastic reset member 233f drives the first opening and closing member 231 to reset to connect the air outlet duct 213a (that is, it moves to the first open position) and the second opening and closing member 232 blocks the air suction duct 110 (that is, it moves to the second closed position). At this time, the switching device 230 is in the second switching state.

[0217] Furthermore, in one embodiment, a first stop protrusion is provided on the air duct section on the air outlet duct 213a that movably cooperates with the first opening and closing member 231, and the first opening and closing member 231 is movably arranged on the side of the first stop protrusion facing away from the air expelling device 220; in this way, when the switching device 230 is in the first switching state, that is, the first opening and closing member 231 blocks the air outlet duct 213a and the second opening and closing member 232 connects the air suction duct 110, the first opening and closing member 231 can be driven by the suction force of the suction side 221 of the air expelling device 220 to fit tightly with the first stop protrusion, thereby increasing the blocking effect of the first opening and closing member 231 on the air outlet duct 213a.

[0218] Similarly, a second stop protrusion is provided on the air duct section on the suction duct 110 that movably cooperates with the second opening and closing member 232, and the second opening and closing member 232 is movably arranged on the side of the second stop protrusion facing away from the air expelling device 220; in this way, when the switching device 230 is in the second switching state, that is, the first opening and closing member 231 connects the air outlet duct 213a and the second opening and closing member 232 blocks the air suction duct 110, the second opening and closing member 232 can be driven by the suction force of the suction side 221 of the air expelling device 220 to fit tightly with the second stop protrusion, thereby increasing the blocking effect of the second opening and closing member 232 on the air outlet duct 213a.

[0219] In addition, please combine Figures 9 to 19The present invention also provides another embodiment of the switching device 230:

[0220] Specifically, see Figures 9 to 19 The switching device includes an air guide portion 300 and an opening and closing portion 400. The air guide portion 300 defines an air guide channel 310, which is provided with two connection ports for communicating with an external channel. The opening and closing portion 400 is movably disposed within the air guide channel 310, capable of moving to a switching state in which it closes one connection port and opens the other. In the switching state, the opening and closing portion 400 defines at least two flow channels communicating with the opened connection port.

[0221] In the technical solution provided by the present invention, the air guide channel 310 formed by the air guide portion 300 can be adapted to connect at least two external channels and, in conjunction with the movable cooperation of the opening and closing portion 400, guide the airflow of the two external channels to the desired channel sections. The opening and closing portion 400 is movable within the air guide channel 310, and can utilize the internal space of the air guide channel 310, so that the installation and movement of the opening and closing portion 400 does not occupy additional space, thereby ensuring that the overall structure of the switching device and the carrier product on which the switching device is installed is more compact. When in the switching state, the opening and closing portion 400 defines at least two flow channels that are connected to the open connection port. Each flow channel can perform targeted operations such as diversion, reversing, and flow regulation on the gas flowing into or out of the external channel connected to the open connection port. This allows the switching device to have a more comprehensive guiding function in addition to the switching function, ultimately helping to better match the switching device with the carrier product it references, and making the switching device more versatile and reliable.

[0222] It should be noted that, in the above and following embodiments, although the channel structure is not limited to a channel with a circular transverse cross-section, the channel structure is generally uniformly defined as having axial, radial and circumferential directions for ease of understanding.

[0223] The opening and closing portion 400 is movably disposed within the air guide channel 310. During its movement, the opening and closing portion 400 can be moved to a switching state of opening one connection port and closing the other connection port. When the two connection ports are the first connection port 321 and the second connection port 331, as described above:

[0224] The opening and closing portion 400 has a second switching state in which it is movable to open the first connection port 321 and cover the second connection port 331. In the second switching state, the passage between the dust storage chamber 212a and the air purging device 220 is connected, and the passage between the dust collection chamber and the air purging device 220 is blocked. The vacuum cleaner device 200 can independently perform a dust collection operation based on the passage between the dust storage chamber 212a and the air purging device 220.

[0225] The opening and closing portion 400 also has a first switching state in which it moves to cover the first connection port 321 and open the second connection port 331. In the first switching state, the passage between the dust storage chamber 212a and the purge device 220 is blocked, and the passage between the dust collection chamber and the purge device 220 is opened. The dust collection station 100 can perform dust extraction operations based on the passage between the dust collection chamber and the purge device 220. The first switching state is generally achieved simultaneously with or after the vacuum cleaner device 200 and the dust collection station 100 are docked.

[0226] In actual application, the switching device can be selectively provided with either a second switching state or a first switching state. Taking the selective provision of the second switching state as an example, when the opening and closing portion 400 moves to the second switching state, the first connection port 321 is opened and the second connection port 331 is covered. However, when the opening and closing portion 400 moves to a state other than the second switching state, depending on actual needs, the first connection port 321 and the second connection port 331 can be both opened or covered.

[0227] Of course, the switching device can also have both a second switching state and a first switching state. In this case, the second switching state and the first switching state can be switched back and forth during the movable stroke of the opening and closing portion 400. For ease of understanding, the following description will take this setting of the switching device as an example.

[0228] It can be understood that the movement of the opening and closing portion 400 can realize the mutual movement and switching between the second switching state and the first switching state, and can also form at least two flow channels that are mutually conductive with the opened connection port. Figure 10 The opened connection port is the first connection port 321 as an example for auxiliary explanation:

[0229] When the first connection port 321 is opened, the dust chamber 212a and the air guide channel 310 of the vacuum cleaner device 200, for example, are connected. Each flow channel is generally arranged to be located downstream of the first connection port 321. In this case, each flow channel forms at least multiple independent flow paths. Gas from the same source (e.g., the dust chamber 212a) passing through the first connection port 321 can flow selectively or simultaneously through each flow channel. When the flow conditions of each flow channel, such as flow direction and flow rate, are the same, each flow channel can act as a diversion channel; and each flow channel can serve as an alternative to any other flow channel. This ensures that if any flow channel is blocked or an abnormality occurs, at least one remaining flow channel is available, and the flow function downstream of the first connection port 321 is disabled. Alternatively, when the flow conditions of each flow channel, such as flow direction and flow rate, differ at least in part, the gas can be directed to different flow channels according to actual needs, making the gas flow more purposeful and diverse.

[0230] In a further embodiment, a mounting hole 340 is provided on the side wall of the air guide channel 310 at a predetermined channel section, and the mounting hole 340 is used to communicate with the air purging device 220, and the mounting hole 340 is specifically communicated with the suction side of the air purging device 220. In this way, no matter whether the first connection port 321 or the second connection port 331 is opened, the corresponding channel between the dust storage chamber 212a and the air purging device 220 or the channel between the dust collecting chamber and the air purging device 220 can be driven by the same air purging device 220 to achieve directional movement of the airflow, which helps to simplify the number of air purging devices 220 and the installation structure, making the overall vacuum cleaner system more compact and reducing manufacturing and maintenance costs.

[0231] Based on one or more of the above embodiments, further details on the specific configuration of the opening and closing portion 400 are as follows:

[0232] It is understandable that the specific structure, movable form, movable direction, etc. of the opening and closing portion 400 can be specifically adjusted according to the specific configuration of the first connection port 321 and the second connection port 331 .

[0233] 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 at intervals along the axial direction of the air guide channel 310: in one embodiment, the opening and closing portion 400 can be set to be movably movable along the axial direction of the air guide channel 310, so that it can be translated to be close to the first connection port 321 and away from the second connection port 331, and translated to be away from the first connection port 321 and close to the second connection port 331, to realize active switching between the second switching state and the first switching state. Alternatively, in one embodiment, the opening and closing portion 400 may be configured to be rotatably connected to a channel wall between the first connection port 321 and the second connection port 331, roughly in the shape of a lever, so that when one section of the opening and closing portion 400 rotates toward the first connection port 321, the other section of the opening and closing portion 400 is driven to rotate away from the second connection port 331; and when one section of the opening and closing portion 400 rotates toward the second connection port 331, the other section of the opening and closing portion 400 is driven to rotate away from the first connection port 321, thereby similarly realizing active switching between the second switching state and the first switching state.

[0234] Alternatively, for example, when the first connection port 321 and the second connection port 331 are disposed on two radially opposite walls of the air guide channel 310 and spaced apart along the radial direction of the air guide channel 310, the opening and closing portion 400 is reciprocally movable between the two connection ports. In the switching state, the opening and closing portion 400 abuts against the side wall of the covered connection port and is spaced apart from the side wall of the opened connection port, thereby defining at least two flow channels with opposite flow directions at the spaced apart locations. For example, the air guide channel 310 has a first channel side wall 320 and a second channel side wall 330 disposed opposite to each other in the radial direction, and the first connection port 321 is disposed on the first channel side wall 320 and the second connection port 331 is disposed on the second channel side wall 330. That is, in the second switching state, the opening and closing portion 400 separates from the first channel side wall 320 to open the first connection port 321, and abuts against the second channel side wall 330 to cover the second connection port 331. At this point, the gap between the opening and closing portion 400 and the first channel sidewall 320 effectively connects the air guide channel 310 at that location, forming at least two flow paths. Conversely, in the first switching state, the opening and closing portion 400 separates from the second channel sidewall 330 to open the second connection port 331, and the opening and closing portion 400 abuts against the first channel sidewall 320 to cover the first connection port 321. At this point, the gap between the opening and closing portion 400 and the second channel sidewall 330 effectively connects the air guide channel 310 at that location, forming at least two flow paths.

[0235] When the first connection port 321 is connected to the dust storage chamber 212a in the vacuum cleaner device 200, and the second connection port 331 is connected to the dust collection chamber in the dust collection station 100 after the vacuum cleaner device 200 is docked with the dust collection station 100, as an example: when the vacuum cleaner device 200 is not docked with the dust collection station 100, that is, when the vacuum cleaner device 200 is operating independently, the opening and closing portion 400 is maintained in the second switching state, that is, the opening and closing portion 400 covers the second connection port 331 and opens the first connection port 321, at this time, the passage between the dust storage chamber 212a and the air purging device 220 remains conductive. After the vacuum cleaner device 200 is docked with the dust collection station 100, the opening and closing portion 400 can be switched to the first switching state under the mechanical triggering of the trigger structure or under the automatic control of a preset program, that is, the opening and closing portion 400 covers the first connection port 321 and opens the second connection port 331, so that the passage between the dust collection chamber and the air purging device 220 is conductive.

[0236] In the above description, the trigger structure can be disposed at the interface between the vacuum cleaner device 200 and the dust collection station 100, with the docking action of the vacuum cleaner device 200 and the dust collection station 100 applying force to the trigger structure, thereby triggering the trigger structure. Alternatively, the trigger structure can be electrically connected to, for example, a sensor device or a control device, and the control device then controls the trigger structure to actuate the opening and closing portion 400 upon receiving a sensing signal from the sensor device.

[0237] Then, the switching activities of the opening and closing part 400 between the second switching state and the first switching state can be directly realized by the trigger structure or the preset program control. Or in one embodiment, the trigger structure or the preset program controls the opening and closing part 400 to switch from the second switching state to the first switching state, and the opening and closing part 400 can be reset from the first switching state to the second switching state by, for example, an elastic component 500. Based on this, in one embodiment, the switching device also includes an elastic component 500, which is connected between the opening and closing part 400 and the air guide part 300; under the drive of an external force, the opening and closing part 400 is driven by the external force to move from one connection port to another connection port; when the external force is removed, the opening and closing part 400 is reset by the elastic component 500. The elastic component 500 is, for example, a spring part, a metal spring, a rubber or silicone part.

[0238] The specific structure of the opening and closing portion 400 is not limited, and can be, but not limited to, a plate, block, column, etc. Figure 13 and Figure 19In one embodiment, the opening and closing portion 400 includes an opening and closing body 410 and an annular step 420 protruding laterally from the outer wall of the opening and closing body 410. The annular step 420 divides the opening and closing body 410 into two main sections. In the switching state, one main section is inserted into a connection port, and the corresponding side step surface of the annular step 420 abuts the peripheral surface of the connection port to cover the connection port. The opening and closing body 410 extends generally along the line connecting the first connection port 321 and the second connection port 331, that is, the first radial direction mentioned above. For ease of understanding, the two main sections of the opening and closing body 410 divided by the annular step 420 are defined as the first main section 411 facing the first connection port 321 and the second main section 412 facing the second connection port 331. The step surface of the annular 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.

[0239] At this time, take the second switching state as an example:

[0240] The opening and closing portion 400 covers the second connection port 331 in the following manner: the second main body section 412 is inserted into the second connection port 331 to achieve a primary sealing cover of the second connection port 331 by the opening and closing portion 400; and the second step surface 422 abuts against the second channel side wall 330 to achieve a secondary sealing cover of the second connection port 331 by the opening and closing portion 400.

[0241] The opening and closing portion 400 may open the first connection port 321 in the following manner:

[0242] In one embodiment, in the switching state, a main body section is detached from a connection port, and the corresponding side step surface of the annular step 420 separates from the peripheral surface of the connection port, thereby opening the connection port. That is, in the second switching state, the first main body section 411 can be completely detached from the first connection port 321 and located within the air guide channel 310. Similarly, the first step surface 421 of the annular step 420 is also completely separated from the first channel sidewall 320. At this point, the first connection port 321 is unobstructed and open.

[0243] Alternatively, in one embodiment, in the switching state, a main body segment is inserted into a connection port, and a gap is formed at the insertion connection between the two. The gap connects the connection port and the air guide channel 310, and the corresponding side step surface of the annular step 420 is separated from the peripheral surface of the connection port, thereby jointly opening the connection port. Specifically, in the second switching state, the first main body segment 411 is fully or partially inserted into the first connection port 321. However, because the outer diameter of the first main body segment 411 is smaller than the aperture of the first connection port 321, a gap is formed between the outer wall of the first main body segment 411 and the aperture wall of the first connection port 321. The first step surface 421 is separated and spaced from the first channel sidewall 320. In this way, for example, gas in the dust storage chamber 212a of the vacuum cleaner device 200 can flow into the air guide channel 310 through this gap after entering the first connection port 321, thereby achieving communication between the first connection port 321 and the air guide channel 310.

[0244] Alternatively, in one embodiment, in the switching state, a main body segment is inserted into a connection port, and the switching device is provided with a connection channel 430 that connects the connection port and the air guide channel 310. The corresponding side step surface of the annular step 420 is separated from the peripheral surface of the connection port to jointly open the connection port. That is, in the second switching state, the first main body segment 411 is fully or partially inserted into the first connection port 321. The outer diameter of the first main body segment 411 can be smaller than the aperture of the first connection port 321, or the outer diameter of the first main body segment 411 can be equal to the aperture of the first connection port 321 at least at the first connection port 321. In this case, the switching device is provided with a connection channel 430 throughout, extending at least from the first connection port 321 into the air guide channel 310, thereby achieving communication between the first connection port 321 and the air guide channel 310.

[0245] Furthermore, taking the above-mentioned connecting channel 430 as an example:

[0246] Please combine Figure 13, the connection channel 430 can be formed inside the switching device, and its side is generally closed, with a first channel opening 431 that penetrates to the first main body section 411, and a second channel opening 432 that penetrates to the outer wall of the switching device. In the switching state, the first channel opening 431 is located in the air guide channel 310, and in the direction away from the opened connection port, the switching device is at least provided with a portion with a gradually decreasing outer diameter at the portion where the first channel opening 431 is provided. 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 at the portion where the first channel opening 431 is provided, that is, at the first main body section 411, is gradually increased 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 main body section 411 can be adapted to different apertures of the first connection port 321 by gradually increasing the outer diameter to achieve targeted insertion and blocking; on the other hand, the first channel opening 431 can be opened on the inclined outer peripheral side wall, with a larger opening area.

[0247] Please combine Figure 19 The connecting channel 430 can also be provided on the outer peripheral side wall of the switching device. The connecting channel 430 penetrates the side wall of the switching device and is open, generally in the form of a slot. In this case, the connecting channel 430 can conduct the first connection port 321 and the air guide channel 310 through the opening.

[0248] It should be noted that the opening and closing body 410 and the annular step 420 described above can be integrally formed, or can be formed separately and then connected in a detachable or non-detachable manner. Furthermore, to achieve flexible contact between the opening and closing portion 400 and the air guide portion 300, at least the outer wall of the main body and / or the annular step 420 can be made of an elastic material, or an elastic layer can be directly installed.

[0249] Based on any of the above embodiments, in a further solution, the switching device further includes an adapting portion 600 for adapting and installing the air guide portion 300 in the area to be installed on the carrier product, the adapting portion 600 is formed with an installation channel 610, the installation channel 610 is connected to a connection port and extends in the same direction; the switching device further includes a mounting portion 700, the mounting portion 700 is connected to the end of the main section away from the annular step 420, and is accommodated in the installation channel 610. Figures 10 to 12 As shown, the installation channel 610 can be connected to the first connection port 321 to extend the length of the first connection port 321 and form enough space for the installation portion 700 to be movably installed.

[0250] The mounting portion 700 and the opening and closing portion 400 can be integrally formed, or they can be separately formed and then connected in a detachable or non-detachable manner. Regardless of whether the opening and closing portion 400 is in the second switching state or the first switching state, the mounting portion 700 is always received in the mounting channel 610, thereby facilitating a more stable installation and smoother movement of the opening and closing portion 400.

[0251] In a further embodiment, a stop protrusion 611 is provided on one of the inner wall of the mounting channel 610 and the outer wall of the mounting portion 700, and a mating protrusion 710 is provided on the other. The stop protrusion 611 abuts against the mating protrusion 710 to prevent the mounting portion 700 from slipping out of the mounting channel 610. Similarly to the above, 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 an elastic material, or an elastic layer can be directly installed.

[0252] In addition, in one embodiment, the adapter portion 600 further defines an extension channel 620 on the sidewall 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 configured to mate with the external channel of the carrier product to which the switching device is mounted. The adapter portion 600 can structurally adapt to the installation between the air guide portion 300 and the carrier product (e.g., the vacuum cleaner device 200); while the extension channel 620 can, for example, adapt to the communication between the dust storage chamber 212a and / or the pre-filter 243 of the vacuum cleaner device 200 and the first connection port 321.

[0253] 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 in a detachable or non-detachable manner. It should be noted that the above does not constitute a limitation on the number of structures of the air guide portion 300 and / or the adapter portion 600, for example Figure 12 As shown, in order to better install the opening and closing part 400, the air guide part 300 can be formed separately from the adapter part 600, and the air guide part 300 itself can be obtained by detachably connecting two shell structures, and when the two are connected, they jointly enclose and define the guide air duct. Figure 18 As shown, the air guide portion 300 and the adapter portion 600 are at least partially integrally formed, and similarly to the above, in order to better install the opening and closing portion 400, the air guide portion 300 and the adapter portion 600 as a whole can be obtained by detachably connecting two shell structures, and when the two are connected, they jointly enclose and define a guide air duct.

[0254] When the connecting channel 430 is provided as described above, the connecting channel 430 may be provided only at the first main body section 411 or may be provided extending between the first main body section 411 and the mounting portion 700 according to actual needs. Figures 10 and 11 In the switching device, a connecting channel 430 is provided between the mounting portion 700 and the adjacent main body section. When the connection port communicating with the mounting channel 610 is opened, the connecting channel 430 communicates with the air guide channel 310 and the mounting channel 610 .

[0255] In view of the above, the air guide channel 310 is arranged in an annular shape. When in a switching state (e.g., the second switching state), the opening and closing portion 400 maintains the air guide channel 310 at least at the open connection port (e.g., the first connection port 321) along its own circumference, thereby defining at least two flow channels that are connected to the open connection port at the connection point. At this time, the airflow entering the air guide channel 310 through the first connection port 321 can flow along one side of the circumference of the air guide channel 310 at that location, forming one flow channel; or it can flow along the other side of the circumference of the air guide channel 310 at that location, forming another flow channel.

[0256] Since the downstream ends of the flow channels are not limited to converging, that is, the length of the flow channels within the air guiding channel 310 is not limited, the flow channels can be formed within a partial channel section of the air guiding channel 310, in which case the opening and closing portion 400 maintains circumferential conductivity within the partial channel section. Alternatively, the flow channels can be formed within the entire air guiding channel 310, in which case the opening and closing portion 400 maintains circumferential conductivity throughout the entire air guiding channel 310.

[0257] When, as described above, the air guide channel 310 is provided with a mounting hole 340 at the channel section radially opposite to the opened connection port, and the mounting hole 340 is used to communicate with the air expulsion device 220, in a further scheme, two connection ports can be opened at two radially opposite side walls of the same channel section of the air guide channel 310, and the connection port and the mounting hole 340 are separately arranged at two radially opposite channel sections of the air guide channel 310. In this way, the first connection port 321, the second connection port 331 and the mounting hole 340 are roughly spaced apart in sequence along the same radial direction of the annular air guide channel 310. On the one hand, it helps to balance the opening and closing part 400 and the air expelling device 220 on both sides of the radial direction of the air guide part 300 and to place them beautifully; on the other hand, it can make the flow conditions of the two flow channels directly formed by the two first channel sections 311 roughly the same, ensuring that the flow parameters of the gas in the two flow channels are roughly the same, especially when the switching device is applied to the vacuum cleaner system, and the center of the annular air guide channel 310 is located on the central axis of the vacuum cleaner device 200, the disturbance caused by the flow of gas in each flow channel to a certain extent can be more balanced or directly offset each other, avoiding the vacuum cleaner device 200 from having greater disturbance on one side, greater noise, etc., which reduces the user experience.

[0258] In addition to the purge device 220 as described above, the vacuum cleaner device 200 may further include a pre-filter 243. The pre-filter 243 is generally annularly arranged at the downstream end of the dust storage chamber 212a. Gas continuing to flow through the dust storage chamber 212a enters the axis of the pre-filter 243 and is ultimately dispersed and discharged radially outward from the pre-filter 243. As a result, the solid residue carried in the gas is trapped in the dust storage chamber 212a by the pre-filter 243.

[0259] When the air guide channel 310 is arranged in a ring shape as described above, and the carrier product installed by the switching device is a vacuum cleaner device 200, the air guide channel 310 can be optionally arranged around the outer periphery of the pre-filter 243 so that the gas discharged to the outside through the pre-filter 243 can enter the air guide channel 310 through, for example, the first connection port 321.

[0260] Specifically, when the adapter portion 600 is included as described above, the adapter portion 600 can achieve adaptive installation between the air guide portion 300 and the pre-filter 243 of the vacuum cleaner device 200. The installation channel 610 of the adapter portion 600 is adapted to extend in the direction of, for example, the first connection port 321 provided on the air guide portion 300, and the extension channel 620 is adapted to extend in the air outlet direction of the downstream side of the pre-filter 243 of the vacuum cleaner device 200.

[0261] Please combine the specific Figures 10 to 12In one embodiment, the air guide channel 310 extends in an annular shape; the pre-filter 243 is cylindrically disposed on one radial side of the air guide channel 310 and located within the annular region of the air guide channel 310. In other words, the orthographic projections of the air guide channel 310 and the pre-filter 243 in the horizontal direction at least partially overlap, which helps to reduce the vertical space occupied by the air guide channel 310 and the pre-filter 243.

[0262] At this time, the pre-filter 243 occupies the inner ring area of ​​the air guide channel 310. Since the adapter part 600 is set as described above, and the adapter part 600 forms an installation channel 610, the installation channel 610 also needs to occupy the inner ring area of ​​the air guide channel 310 to a certain extent. Therefore, in a further scheme, the transverse cross-section of the pre-filter 243 is oblate and eccentrically arranged in the inner ring area of ​​the air guide channel 310 to make room for the connection port and / or the installation channel 610 that is connected to the extension channel 620 to be extended.

[0263] Or specifically combined Figures 14 to 17 In one embodiment, the air guide channel 310 extends in an annular shape; the prefilter 243 is cylindrically arranged on one axial side of the air guide channel 310, and the orthographic projection of the prefilter 243 in the axial direction of the air guide channel 310 falls within the annular region of the air guide channel 310. That is, the orthographic projections of the air guide channel 310 and the prefilter 243 in the lateral direction are offset vertically. The prefilter 243 can be arranged above or below the air guide channel 310. In this way, the orthographic projection of the prefilter 243 in the vertical direction still falls within the annular region of the air guide channel 310, or at least partially overlaps with the air guide channel 310, but does not occupy the annular region of the air guide channel 310. Therefore, the specifications of the prefilter 243 are not limited and can be conventional. The extension channel 620 extends radially from the prefilter 243, then bends upward or downward to extend radially or axially connect to the mounting channel 610. Specific implementation 3:

[0265] See also Figures 1 to 19 The present invention provides a vacuum cleaner system, which may be but is not limited to the vacuum cleaner system described in one or more of the above embodiments.

[0266] The vacuum cleaner system includes a vacuum cleaner device 200, a dust collection station 100, and a switching device 230. The vacuum cleaner device 200 includes a grip and an air purging device 220. The dust collection station 100 is used to dock with the vacuum cleaner device 200, and the dust collection station 100 includes a dust collection chamber for collecting dust. After the vacuum cleaner device 200 and the dust collection station 100 are docked, the switching device 230 selectively connects the air purging device 220 with the dust collection chamber. In this design, the switching device 230 is used to selectively connect or disconnect the air purging device 220 from the dust collection chamber.

[0267] Furthermore, in one embodiment, an independently working dust collection duct is formed in the vacuum cleaner device 200; after the vacuum cleaner device 200 is docked with the dust collection station 100, the vacuum cleaner system is further formed with a dust extraction duct, and a dust collection chamber is provided on the dust extraction duct. The dust extraction duct is used to transfer the dirt collected by the vacuum cleaner device 200 to the dust collection chamber, and the switching device 230 is used to selectively connect the dust collection duct or the dust extraction duct. When the switching device 230 connects the dust collection duct, the dust collection duct can perform an independent dust collection operation under the action of the air purging device 220 or regardless of the action of the air purging device 220. When the switching device 230 connects the dust extraction duct, the switching device 230 can connect the air purging device 220 and the dust collection chamber, and can transfer the dirt collected by the vacuum cleaner device 200 to the dust collection chamber. It should be noted that the dirt collected by the vacuum cleaner device 200 is not limited to being stored in the dust collection duct, but can also be stored in other areas except the dust collection duct.

[0268] Further, when the switching device 230 has a first switching state and a second switching state, it can be specifically defined that in the first switching state, the dust suction duct is opened; and / or in the second switching state, the dust extraction duct is opened.

[0269] Specifically, in one embodiment, the vacuum cleaner device 200 includes an air inlet 211 and a dust storage section 212. The dust storage section 212 has a dust storage chamber 212a for storing dirt. The air inlet 211 and the dust storage section 212 can be the structures of the above-mentioned embodiment, or can be other structural designs. The dust collection duct sequentially connects the air inlet 211, the dust storage chamber 212a, and the air purging device 220. In this way, when the dust collection duct is turned on by the switching device 230, the flow path between the air inlet duct, the dust storage chamber 212a, and the air purging device 220 is connected, and external dirt can be brought into the air inlet duct by the gas and trapped in the dust storage chamber 212a. The relatively clean gas is discharged to the outside through the exhaust side 222 of the air purging device 220. Among them, when the air outlet portion 213 is also included as described above, external dirt can be brought into the air inlet duct by the gas and trapped in the dust storage chamber 212a. The relatively clean gas flows through the air outlet duct 213a and is finally discharged outward through the exhaust side 222 of the air purging device 220, completing the dust collection operation. And / or, the dust extraction duct is connected to the dust storage chamber 212a, the dust collecting chamber and the air purging device 220 in sequence. In this way, when the dust extraction duct is turned on by the switching device 230, the flow path between the dust storage chamber 212a, the dust collecting chamber and the air purging device 220 is connected, and the dirt in the dust storage chamber 212a can enter the dust collecting chamber under the drive of the air purging device 220, completing the dust extraction operation.

[0270] In addition, in one embodiment, the vacuum cleaner device 200 further includes a pre-filter 243 located downstream of the dust storage chamber 212a and upstream of the air purging device 220. The dust suction air duct passes through the pre-filter 243, that is, the gas entering the suction side 221 of the air purging device 220 through the dust suction air duct will be filtered by the pre-filter 243 before entering the air purging device 220, which helps to ensure that the gas entering the air purging device 220 is relatively clean, and prevents some of the dirt in the dust storage chamber 212a from being driven into the air purging device 220, causing blockage of, for example, the suction side 221 or the exhaust side 222 of the air purging device 220. The dust extraction air duct does not pass through the pre-filter 243. That is, the pre-filter 243 will not be set between the dust collecting chamber and the suction side 221 of the air purging device 220, so as to prevent the pre-filter 243 from affecting the dust extraction effect.

[0271] In one embodiment, the dust extraction duct has an air duct outlet 215c connecting the vacuum cleaner device 200 and the dust collection station 100. The air duct outlet 215c is close to the pre-filter 243, which helps to make the structure of the whole machine compact.

[0272] In addition, in one embodiment, the dust extraction duct includes a connecting duct 214 connecting the pre-filter 243 and the air purging device 220, and at least part of the connecting duct 214 is arranged on 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 purging device 220 is the outlet duct 213a. When the pre-filter 243 is sufficiently close to the downstream of the dust storage chamber 212a, the connecting duct 214 is basically the outlet duct 213a. When there is a distance between the pre-filter 243 and the downstream of the dust storage chamber 212a, the pre-filter 243 divides the outlet duct 213a into two duct sections, wherein the duct section located between the pre-filter 243 and the air purging device 220 constitutes the connecting duct 214. At least part of the connecting duct 214 is arranged around the periphery of the pre-filter 243, wrapping the pre-filter 243 in the ring, which helps to make the structure of the whole machine compact.

[0273] Furthermore, the connecting air duct 214 may be arranged to surround the outer circumference of the pre-filter 243 in a spiral shape. The spiral shape may specifically refer to a single-circle ring shape or a multi-circle ring shape. The single-circle ring shape may surround the entire circumference or may be a partial ring shape consisting of arc segments.

[0274] In addition, the following are specific embodiments of the switching device 230:

[0275] The vacuum cleaner device 200 is provided with a dust storage chamber 212a for storing dirt and an air outlet duct 213a connecting the dust storage chamber 212a and the air expelling device 220. The vacuum cleaner system is provided with a suction duct 110 connecting the air expelling device 220 and the dust collecting chamber. The switching device 230 includes an opening and closing structure, which selectively connects the outlet duct 213a and blocks the suction duct 110, or connects the suction duct 110 and blocks the outlet duct 213a.

[0276] The vacuum cleaner device 200 is provided with a dust storage chamber 212a for storing dirt and an air outlet duct 213a connecting the dust storage chamber 212a and the air expelling device 220. The switching device 230 includes a first opening and closing member 231, which is movably installed on the air outlet duct 213a so as to be able to movably open and close the air outlet duct 213a.

[0277] The vacuum cleaner system includes a suction duct 110 connecting the air expelling device 220 and the dust collecting station 100. The switching device 230 includes a second opening and closing member 232, which is movably installed in the suction duct 110 to be able to movably open and close the suction duct 110.

[0278] The vacuum cleaner device 200 is provided with a dust storage chamber 212a for storing dirt and an air outlet duct 213a connecting the dust storage chamber 212a with the air expelling device 220. The vacuum cleaner system is provided with a suction duct 110 connecting the air expelling device 220 and the dust collecting chamber. The switching device 230 includes 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 be able to movably connect and block the air outlet duct 213a; the second opening and closing member 232 is movably installed in the suction duct 110 so as to be able to movably connect and block the suction duct 110; wherein, when the first opening and closing member 231 connects the air outlet duct 213a, the second opening and closing member 232 blocks the suction duct 110, and when the first opening and closing member 231 blocks the air outlet duct 213a, the second opening and closing member 232 connects the suction duct 110.

[0279] The first opening and closing member 231 and the second opening and closing member 232 are independently movable; or,

[0280] The first opening and closing member 231 and the second opening and closing member 232 are linked together.

[0281] The switching device 230 also includes a linkage mechanism, which links the first opening and closing member 231 and the second opening and closing member 232, so that the first opening and closing member 231 and the second opening and closing member 232 move in the same direction during the process of opening the air outlet duct 213a or the air intake duct 110.

[0282] The switching device 230 further includes a trigger member 234 connected to the linkage mechanism, the first opening and closing member 231 and / or the second opening and closing member 232 to have a trigger stroke that drives the first opening and closing member 231 and the second opening and closing member 232 to move in the same direction under external force.

[0283] The trigger member 234 is disposed at the docking position between the vacuum cleaner device 200 and the dust collecting station 100 . After the vacuum cleaner device 200 is docked with the dust collecting station 100 , the trigger member 234 is driven to perform a triggering stroke.

[0287] It should be noted that, for other applications of the switching device in this embodiment, reference may be made to the relevant descriptions in Specific Implementation 2, and no further description is given here. Specific implementation 4:

[0289] See also Figures 1 to 19 The present invention provides a vacuum cleaner system, which may be but is not limited to the vacuum cleaner system described in one or more of the above embodiments.

[0290] Specifically, the vacuum cleaner system includes a dust collecting station 100 and a vacuum cleaner device 200. The dust collecting station 100 is provided with a dust collecting chamber. The vacuum cleaner device 200 includes an air expelling device 220. A dust storage chamber 212a is provided in the vacuum cleaner device 200. After the vacuum cleaner device 200 is docked with the dust collecting station 100, the vacuum cleaner system has an air duct connecting the dust collecting chamber and the dust storage chamber 212a. The air expelling device 220 generates negative pressure in the dust collecting chamber to suck the dirt in the dust storage chamber 212a into the dust collecting chamber through the air duct.

[0291] It can be understood that the air duct is connected at least after the vacuum cleaner device 200 and the dust collecting station 100 are docked. Before the vacuum cleaner device 200 and the dust collecting station 100 are docked, the air duct may not be formed, or the air duct has been formed but is not connected, and is in a partitioned state. The air duct can be set to one or at least two according to actual needs. When it is set to at least two, each air duct can be connected at both ends to connect the dust storage chamber 212a and the dust collecting chamber to form a plurality of air ducts arranged in parallel; or each air duct can be formed between the dust storage chamber 212a and the dust collecting chamber to be connected end to end in sequence to form a plurality of air ducts arranged in series.

[0292] In order to enable the air displacing device 220 to form a negative pressure in the dust collecting chamber after the vacuum cleaner equipment 200 and the dust collecting station 100 are docked, specifically, when an air duct is formed between the dust collecting chamber and the dust storage chamber 212a, the suction side 221 is connected to the dust collecting chamber, and the driving gas is sucked into the dust collecting chamber from the dust storage chamber 212a carrying the dirt; and / or when an air duct is formed between the dust collecting chamber and the dust storage chamber 212a, the exhaust side 222 is connected to the dust storage chamber 212a, and the driving gas is blown into the dust collecting chamber from the dust storage chamber 212a carrying the dirt.

[0293] When the air duct is defined by a specific shell:

[0294] In one embodiment, the housing can be a fixed structure within the vacuum cleaner device 200, for example, defined by the housing, or defined by other components disposed within the housing. The air duct is connected to the dust storage chamber 212a, and the connection between the two can be switched between a conducting state and a blocking state.

[0295] And / or in one embodiment, the housing may be a structure fixed within the dust collection station 100, for example, defined by the outer shell of the dust collection station 100, or defined by other components disposed within the outer shell of the dust collection station 100. The air duct and the dust collection chamber are connected, and the connection between the two can be switched between a conducting state and a blocking state.

[0296] Of course, the housing can also be a structure that is independent of the vacuum cleaner device 200 and the dust collection station 100, for example, it can be external to the vacuum cleaner device 200 and the dust collection station 100. When the vacuum cleaner device 200 and the dust collection station 100 are docked, the air duct is connected to the dust storage chamber 212a and the dust collection chamber in a switchable manner. Specific implementation 5:

[0298] See also Figures 1 to 12 The present invention provides a vacuum cleaner system, which may be but is not limited to the vacuum cleaner system described in one or more of the above embodiments.

[0299] The vacuum cleaner system includes a dust collection station 100 and a vacuum cleaner device 200. The dust collection station 100 is provided with a dust collection chamber. The vacuum cleaner device 200 includes a grip, an air purging device 220, and a switching device 230. The vacuum cleaner device 200 is provided with a dust suction duct, which defines a dust storage chamber 212a. The air purging device 220 has a suction side 221, which is connected to the dust suction duct. After the vacuum cleaner device 200 and the dust collection station 100 are docked, the switching device 230 forms a dust extraction duct between the suction side 221, the dust storage chamber 212a, and the dust collection chamber. The switching device 230 can selectively connect the dust suction duct and the dust extraction duct. When the dust extraction duct is connected, the air purging device 220 generates a negative pressure in the dust collection chamber.

[0300] In this design, when the switching device 230 opens the dust suction duct, the purge device 220 can act within the dust suction duct, sucking in dirt and directly trapping it within the dust storage chamber 212a, completing the dust suction operation. When the vacuum cleaner device 200 is docked with the dust collection station 100, the suction side 221, the dust storage chamber 212a, and the dust collection chamber are connected and can be switched on by the switching device 230, so that dirt in the dust storage chamber 212a can be transferred to the dust collection chamber, completing the dust suction operation.

[0301] Furthermore, in one embodiment, after the vacuum cleaner device 200 is docked with the dust collection station 100, the switching device 230 can selectively connect or disconnect the air duct section between the dust storage chamber 212a and the dust collection chamber in the dust extraction air duct. Thus, the user can, based on actual needs, operate the switching device 230 to enable dust extraction when the dust storage chamber 212a and the dust collection chamber are connected; conversely, when the dust storage chamber 212a and the dust collection chamber are disconnected, dust extraction is not enabled. However, by creating a negative pressure within the dust collection chamber, operations such as compressing dirt within the dust collection chamber or transferring dirt from other areas into the dust collection chamber can be accomplished.

[0302] In one embodiment, after the vacuum cleaner 200 is docked with the dust collection station 100, the switching device 230 can selectively open or close the air duct section between the suction side 221 and the dust collection chamber. This allows the user to select whether to create a negative pressure in the dust collection chamber via the suction side 221 by operating the switching device 230, based on actual needs. This helps prevent the suction side 221 from disturbing the environment in the dust collection chamber, especially in applications where negative pressure is not required.

[0303] Related to the description in the above-mentioned specific embodiment 2, the air expelling device 220 can be movably arranged, and the switching device 230 can directly act on the air expelling device 220 to drive the air expelling device 220 to move, so that the suction side 221 can be moved to connect with the dust storage chamber 212a and to connect with the dust collecting chamber.

[0304] Or in one embodiment, the partial air duct sections of the dust suction duct and the dust extraction duct are shared to form a common air duct section 215a, and the suction side 221 is arranged at the common air duct section 215a; the air duct section of the dust extraction duct other than the common air duct section 215a is the remaining dust extraction section 111a, and the air duct section of the dust suction duct other than the common air duct section 215a is the remaining dust suction section 215b, and the switching device 230 is movably arranged at the remaining dust suction section 215b and the remaining dust extraction section 111a.

[0305] It can be understood that, referring to the description in the above-mentioned specific embodiments 2-3, the air duct section located between the downstream of the dust storage chamber 212a and the suction side 221 in the dust collection duct is the outlet duct 213a, and the air duct section located between the downstream of the pre-filter 243 and the suction side 221 is the connecting duct 214. Taking the connecting duct 214 as an example, in this case, the remaining dust extraction section 111a can be connected to the side wall of the connecting duct 214, and the connection between the two constitutes the air duct outlet 215c. The air duct outlet 215c directly divides the connecting duct 214 into a common air duct section 215a connected to the suction side 221 and a remaining dust collection section 215b connected downstream of the pre-filter 243. The common air duct section 215a and the remaining dust extraction section 111a together constitute the entire dust collection duct or a portion thereof. The switching device 230 is movably arranged in the remaining dust suction section 215b and the remaining dust extraction section 111a, which can not only realize the opening and closing control of the remaining dust suction section 215b and the remaining dust extraction section 111a separately and independently, but also reduce the interference to the suction side 221.

[0306] Next, in one embodiment, the vacuum cleaner device 200 further includes at least one filter element, each of which is sequentially arranged within the dust collection duct; wherein a common duct section 215a is formed on the outlet side of at least one filter element. This allows the air flowing through the dust collection duct to the common duct section 215a to pass through the at least one filter element, resulting in a relatively cleaner flow, and prevents large solid residue from clogging the common duct section 215a, which could prevent the dust extraction duct and the dust collection duct from being switched on by the switching device 230.

[0307] Furthermore, in one embodiment, the vacuum cleaner device 200 further includes at least one filter element, each of which is sequentially arranged within the dust collection duct; wherein a common duct section 215a is formed on the outlet side of all the filter elements. This allows air flowing through the dust collection duct to the common duct section 215a to pass through all the filter elements, further preventing large solid residue from clogging the common duct section 215a, which could prevent the dust extraction duct and the dust collection duct from being switched on by the switching device 230.

[0308] Furthermore, when the filter element closest to the air intake side 221 is the pre-filter 243, as described above, the pre-filter 243 is cylindrically configured, and the dust collection duct section located on the outlet side of the pre-filter 243 (i.e., the connecting duct 214) is arranged in a spiral shape along the periphery of the pre-filter 243. The shared duct section 215a is formed downstream of the connecting duct 214. The spiral configuration can be referred to above, which helps to make the overall structure more compact.
