Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning equipment auxiliary device and a cleaning system. Background Technology

[0002] With the increasing popularity of handheld cleaning devices, users are demanding greater ease of use. Besides cleaning floors, crevices, and soft surfaces, these products typically include a base station for parking, accessory storage, charging, and dust cup emptying. Especially for handheld cleaning devices with dust cups, existing technologies include base stations that can centrally collect dust from the cup after docking with the device, reducing the need for frequent manual emptying.

[0003] However, in the existing technology, after the handheld cleaning device is docked with the base station, there is a lack of reasonable matching between the mass distribution of the handheld cleaning device and the placement of the heavier components inside the base station. This can easily lead to an unsatisfactory overall center of gravity distribution in the docked state. If the layout is unreasonable, the stability of the handheld cleaning device after docking may be poor, and there is a risk of it tilting forward, tilting to the side, or falling off the docking position after being disturbed by external forces. This will affect the reliability of the automatic dust collection process and the overall user experience.

[0004] For vacuum cleaners, especially when the dust cup's central axis is perpendicular to the base station's central axis, placing the handheld cleaning device in front of or behind the base station can cause the cleaning system's center of gravity to shift beyond the preset range. Furthermore, when the cleaning system is placed behind the base station, its center of gravity is usually located at the edge of the base station's housing. When there is external shaking or the self-collecting motor starts, its charging interface is prone to disconnection or poor contact, and it is also prone to tipping over due to instability. This also greatly increases noise. For example, in the case of announcement number CN223958754U, when the handheld vacuum cleaner is docked with the base station, the central axis of its dust cup is basically perpendicular to the central axis of the base station. However, on the one hand, the dust cup is too high in its height direction, and the docking surface between the dust cup and the base station docking cavity is too small; on the other hand, the handheld vacuum cleaner is relatively large in the height direction along the central axis of the dust cup. As a result, when docked, the center of gravity of the cleaning system deviates from the vertical projection plane of the dust collection motor and is closer to the edge of the base station shell, which poses a risk of tipping over. In addition, the base station is prone to shaking when charging and in self-dust collection mode, which is not good for reliability and overall user experience. Utility Model Content

[0005] The purpose of this application is to provide a cleaning equipment auxiliary device and a cleaning system, so as to at least solve the problems of poor stability and low reliability of automatic dust collection after the cleaning equipment and the cleaning equipment auxiliary device are connected in the prior art.

[0006] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application.

[0007] According to one aspect of this application, a cleaning equipment auxiliary device is provided, the cleaning equipment auxiliary device comprising:

[0008] The device body has a receiving cavity and a cleaning equipment docking cavity. The receiving cavity includes a dust collection cavity for storing dust from the cleaning equipment and a storage cavity for storing cleaning parts. The dust collection cavity and the storage cavity are spaced apart along the height direction of the device body.

[0009] The dust collection motor is located inside the main body of the device;

[0010] The cleaning equipment auxiliary device has a docking state. In the docking state, at least a portion of the cleaning equipment is located in the docking cavity of the cleaning equipment, so that the dust cup of the cleaning equipment is in fluid communication with the receiving cavity through the docking cavity. The dust collection motor is activated to generate negative pressure inside the receiving cavity, thereby drawing dust from the dust cup of the cleaning equipment into the receiving cavity. The orthogonal projection of the center of gravity of the cleaning equipment on a plane perpendicular to the height direction is located within the orthogonal projection range of the dust collection motor on that plane.

[0011] By incorporating a receiving cavity, a cleaning equipment docking cavity, and a dust collection motor within the device body, and ensuring that the orthographic projection of the cleaning equipment's center of gravity in the docked state onto a plane perpendicular to its height falls within the orthographic projection range of the dust collection motor on that plane, automatic dust collection can be achieved while simultaneously concentrating the main weight area of ​​the cleaning equipment with the heavier components inside the auxiliary devices. This improves the stability of the cleaning equipment after docking, thereby reducing the risk of shaking, tilting, or detachment caused by excessive center of gravity shift during automatic dust collection, and ultimately enhancing the reliability of automatic dust collection.

[0012] In some example embodiments of this application, based on the foregoing scheme, the orthogonal projection of the dust collection motor toward the dust collection chamber is located within the orthogonal projection range of the dust collection chamber itself;

[0013] And / or, the orthographic projection of the dust collection motor toward the storage cavity is located within the orthographic projection range of the storage cavity itself.

[0014] By positioning the orthographic projection of the dust collection motor toward the dust collection chamber and / or the storage chamber within the orthographic projection range of the corresponding chamber, the dust collection motor and the functional chamber can be arranged in a more concentrated manner in space, thereby improving the utilization rate of the internal space of the device and helping to improve the overall center of gravity distribution.

[0015] In some example embodiments of this application, based on the foregoing scheme, along the height direction, the storage cavity is located above the dust collection cavity, and the orthographic projection of the storage cavity on the plane is at least partially located within the orthographic projection range of the dust collection cavity on the plane;

[0016] Alternatively, along the height direction, the dust collection chamber is located above the storage chamber, and the orthographic projection of the dust collection chamber onto the plane is within the orthographic projection range of the storage chamber onto the plane.

[0017] By arranging the storage chamber and the dust collection chamber at intervals in the height direction, and ensuring that the orthographic projection of one chamber falls at least partially within the orthographic projection range of the other chamber, the two functional chambers can form a compact layout of vertical stacking. Secondly, the overlap of the chambers in the plane helps to reduce lateral occupancy and improve the overall structural stability.

[0018] In some example embodiments of this application, based on the foregoing scheme, the orthographic projection of the dust collection motor on the plane is at least partially located within the orthographic projection range of the storage cavity on the plane, and at least partially located within the orthographic projection range of the dust collection cavity on the plane.

[0019] By ensuring that the orthographic projection of the dust collection motor on the plane is at least partially within the orthographic projection range of the receiving cavity and the dust collection cavity, the dust collection motor can be positioned in a relatively concentrated position between the two functional areas, thereby reducing the adverse effects of off-center loading and helping to improve the force balance of the auxiliary devices of the cleaning equipment during operation.

[0020] In some example embodiments of this application, based on the foregoing scheme, along the height direction, the cleaning equipment docking cavity is located between the top and bottom ends of the device body, close to the top end, and the orthographic projection of the cleaning equipment docking cavity toward the receiving cavity does not fall within the orthographic projection range of the receiving cavity.

[0021] By positioning the cleaning equipment docking cavity close to the top of the device body, and ensuring that its orthographic projection toward the receiving cavity does not fall within the orthographic projection range of the receiving cavity, the docking area can be spatially separated from the dust collection and storage area, thereby reducing mutual interference and providing a more complete structural space for the arrangement of components inside the receiving cavity.

[0022] In some example embodiments of this application, based on the aforementioned scheme, the device body is provided with a motor exhaust port, and along the height direction, the motor exhaust port is located below the receiving cavity; and the dust collection motor is arranged close to the motor exhaust port.

[0023] By setting the motor exhaust port below the housing cavity and placing the dust collection motor close to the motor exhaust port, the exhaust path can be shortened and the exhaust resistance reduced, thereby improving the smoothness of exhaust; at the same time, it is beneficial to dissipate the heat generated by the dust collection motor in a timely manner, thereby improving the operational stability.

[0024] In some example embodiments of this application, based on the foregoing scheme, the dust collection chamber includes a dust collection chamber cover, which can pivot along the pivot axis L1 of the device body to open or close the dust collection chamber;

[0025] And / or, the storage cavity includes a storage cavity cover, which is pivotable along the pivot axis L2 of the device body to open or close the storage cavity;

[0026] Wherein, the pivot axis L1 and the pivot axis L2 are collinear along the height direction;

[0027] Alternatively, when the dust collection chamber cover is closed, the dust collection chamber cover has a cover fit line M1;

[0028] When the storage cavity cover is closed, the storage cavity cover has a cover line M2;

[0029] Wherein, the cover line M1 and the cover line M2 are collinear along the height direction.

[0030] By making the pivot axes of the dust collection chamber cover and the storage chamber cover collinear, and / or making their closing lines collinear, the two opening and closing structures can form a unified arrangement on the device body, thereby simplifying assembly positioning and appearance treatment; secondly, it is also beneficial to improve the consistency of opening and / or closing actions.

[0031] In some example embodiments of this application, based on the foregoing solution, the device body is further provided with a fixed bracket, which supports and fixes the dust collection motor so that the orthographic projection of the dust collection motor toward the dust collection chamber is within the orthographic projection range of the dust collection chamber itself; and / or, so that the orthographic projection of the dust collection motor toward the storage chamber is within the orthographic projection range of the storage chamber itself.

[0032] By setting up fixed brackets to support and fix the dust collection motor and keeping it within the predetermined orthogonal projection range, the stability and accuracy of the dust collection motor's installation position can be improved, thereby reducing the impact of factors such as vibration and assembly deviation on the center of gravity layout and operational reliability.

[0033] In some example embodiments of this application, based on the foregoing scheme, the storage cavity is provided with at least one storage part, and the cleaning component is detachably connected to the storage part; wherein, the storage part includes at least two storage positions, and the at least two storage positions are used to limit and / or detachably fix the ends of at least two of the cleaning components.

[0034] By setting at least one storage section in the storage cavity and using at least two storage positions to limit and / or detachably fix multiple cleaning parts, the cleaning parts can be classified and stored in an orderly manner, thereby reducing the situation of cleaning parts scattering and colliding in the storage cavity and improving the convenience of users to pick up and put away.

[0035] In some example embodiments of this application, based on the foregoing scheme, the dust collection motor has a motor rotation axis. In the docking state, the distance between the orthographic projection of the center of gravity of the cleaning device on a plane perpendicular to the height direction and the orthographic projection of the motor rotation axis on the plane is less than a first preset distance.

[0036] By limiting the distance between the orthographic projection of the center of gravity of the cleaning equipment and the orthographic projection of the motor rotation axis to be less than a first preset distance under the docking state, the relative positional relationship between the center of gravity and the central area of ​​the dust collection motor can be quantitatively constrained, thereby reducing the flipping tendency caused by the eccentric arrangement and further improving the docking stability.

[0037] In some example embodiments of this application, based on the foregoing scheme, the cleaning device includes a cleaning component;

[0038] When the cleaning component is located in the storage cavity, the extension line of the center of gravity of the cleaning device has a second preset distance from the rotation axis of the motor, and the second preset distance is less than or equal to the first preset distance.

[0039] By limiting the second preset distance between the extended line of the cleaning device's center of gravity and the motor's rotation axis to be less than or equal to the first preset distance when the cleaning component is located in the storage cavity, a better center of gravity relationship can be maintained even when the accessory is stored, thereby reducing the adverse impact of accessory storage on overall stability.

[0040] In some example embodiments of this application, based on the foregoing scheme, the dust cup docking cavity includes a docking surface, and in the docking state, the outer wall surface of the dust cup abuts against the docking surface; in the height direction, the horizontal distance between the docking surface and the central axis of the dust cup is a third preset distance, and the third preset distance is less than or equal to 60mm.

[0041] By aligning the outer wall of the dust cup with the mating surface and limiting the horizontal distance between the mating surface and the central axis of the dust cup to less than or equal to 60mm, the mating support position can be made closer to the central axis area of ​​the dust cup, thereby reducing the overturning torque caused by excessive deviation of the support position and improving the reliability of dust cup alignment.

[0042] According to a second aspect of this application, a cleaning system is provided, comprising:

[0043] A cleaning device includes a dust cup and a battery, the battery being connected to a power receiving interface, and the dust cup including a dust cup cover;

[0044] Auxiliary devices for cleaning equipment include the device body, dust collection motor, charging interface, and dust collection port;

[0045] The device body has a receiving cavity and a cleaning equipment docking cavity. The receiving cavity includes a dust collection cavity for storing dust from the cleaning equipment and a storage cavity for storing cleaning parts. The cleaning equipment docking cavity includes a battery docking cavity and a dust cup docking cavity.

[0046] The dust collection motor is installed inside the device body;

[0047] The charging interface is located inside the battery docking cavity;

[0048] The dust collection port is located in the dust cup docking cavity;

[0049] Along the height direction of the device body, the dust collection chamber and the storage chamber are spaced apart;

[0050] The cleaning equipment auxiliary device has a docking state. In the docking state, the battery is at least partially located in the battery docking cavity, the charging interface is electrically connected to the power receiving interface, the dust cup is at least partially located in the dust cup docking cavity, and the dust cup cover is aligned with the dust collection port.

[0051] The relative positions of the battery docking chamber and the dust cup docking chamber are configured such that, in the docking state, the orthographic projection of the center of gravity of the cleaning device on a plane perpendicular to the height direction is within the orthographic projection range of the dust collection motor on that plane.

[0052] By setting up a battery docking chamber, a dust cup docking chamber, a charging interface, and a dust collection port in the cleaning system, and limiting the relative positions of the two, the cleaning equipment can simultaneously achieve charging and automatic dust collection when docked; thus, it can improve the overall user experience while ensuring the stability of the center of gravity on the basis of multi-functional integration.

[0053] In some example embodiments of this application, based on the foregoing solution, the dust cup includes a dust cup body, and the dust cup cover is rotatably disposed on the dust cup body;

[0054] The cleaning equipment auxiliary device includes an unlocking component, which is located at the dust collection port;

[0055] The unlocking component is configured as follows:

[0056] When the cleaning device moves to the preset unlocking position, the dust cup cover is triggered to unlock, and the dust cup cover is switched from the locked state to the openable state.

[0057] And / or, when the cleaning device is removed from the unlocked position, the trigger for unlocking the dust cup cover is released, causing the dust cup cover to switch from the openable state to the locked state.

[0058] By setting an unlocking mechanism, and triggering the dust cup cover to unlock when the cleaning equipment moves to a preset unlocking position and deactivating the trigger when it leaves the unlocking position, the dust cup cover can be automatically unlocked during docking and automatically re-locked during exiting, thereby reducing manual operation and lowering the risk of accidental opening.

[0059] In some example embodiments of this application, based on the foregoing scheme, in the docking state, the dust collection motor is started to form a negative pressure airflow between the docking chamber of the cleaning equipment and the receiving chamber, and the negative pressure airflow is used to drive the dust cup cover in the waiting-to-open state to switch to the open state;

[0060] The cleaning device includes a reset component, which connects the dust cup cover and the dust cup body.

[0061] The reset component is configured to drive the dust cup cover from the open state to the ready-to-open state after the dust collection motor stops running.

[0062] By using negative pressure airflow to drive the dust cup cover in the ready-to-open state to open automatically, and by using a reset component to drive the dust cup cover back to the ready-to-open state after the dust collection motor stops running, the opening and resetting of the dust cup cover can be automatically linked with the self-dust collection process, thereby improving the continuity of action and structural reliability.

[0063] In some example embodiments of this application, based on the foregoing scheme, the dust cup has a central axis;

[0064] The dust collection motor has a motor rotation axis;

[0065] In the docking state, the central axis of the dust cup is substantially perpendicular to the rotation axis of the motor;

[0066] Alternatively, the cleaning device includes a suction pipe connected to the dust cup, the suction pipe having a central axis; the central axis of the dust cup and the central axis of the suction pipe together define a first plane; the rotation axis of the motor is parallel to the first plane.

[0067] By making the central axis of the dust cup substantially perpendicular to the axis of rotation of the motor, and / or by making the first plane jointly defined by the central axis of the dust cup and the central axis of the suction pipe parallel to the axis of rotation of the motor, the geometric layout relationship between the dust cup, the suction pipe and the dust collection motor can be optimized, thereby facilitating the formation of a more reasonable airflow path and weight distribution.

[0068] In some example embodiments of this application, based on the foregoing scheme, the cleaning device includes a main motor, which is located at the end of the dust cup away from the dust cup cover;

[0069] In the docked state, the battery is positioned above the dust cup; the weight of the main motor is greater than the weight of the battery, so that the center of gravity of the cleaning device in the docked state is biased towards the dust collection motor.

[0070] By positioning the main motor at the end of the dust cup furthest from the dust cup cover, placing the battery above the dust cup, and ensuring the main motor's weight is greater than the battery's weight, the greater weight of the main motor can shift the cleaning equipment's center of gravity towards the dust collection motor side. This reduces the adverse effects of the high-positioned battery on the upward shift of the center of gravity and improves docking stability.

[0071] According to a third aspect of this application, a cleaning system is provided, comprising:

[0072] Cleaning equipment;

[0073] A cleaning equipment auxiliary device includes a device body, the device body having a receiving cavity and a cleaning equipment docking cavity, the receiving cavity being used to store dust from the cleaning equipment and / or to store cleaning parts of the cleaning equipment;

[0074] The cleaning system has a docking state, in which the cleaning equipment is located in the docking cavity of the cleaning equipment, and the center of gravity of the cleaning system is located in the receiving cavity.

[0075] By limiting the center of gravity of the cleaning system to be located within the receiving cavity in the docking state, the center of gravity of the cleaning system formed by the cleaning equipment and the cleaning equipment auxiliary device can fall within the main body range of the cleaning equipment auxiliary device, thereby reducing the risk of tipping caused by the outward shift of the system's center of gravity and improving the overall docking stability.

[0076] In some example embodiments of this application, based on the foregoing scheme, the receiving cavity includes:

[0077] A storage cavity for storing the cleaning components;

[0078] The dust collection chamber is used to store dust from the cleaning equipment;

[0079] In this configuration, the storage cavity and the dust collection cavity are spaced apart along the height direction of the device body, and the storage cavity is located above the dust collection cavity. In the docking state, the center of gravity of the cleaning system is located inside the dust collection cavity.

[0080] By positioning the storage chamber above the dust collection chamber, and ensuring that the center of gravity of the cleaning system is located within the dust collection chamber when docked, the main weight area of ​​the cleaning system can be lowered to a lower position, thereby reducing the overall center of gravity height; thus improving the anti-tilting ability of the cleaning system after docking.

[0081] In some example embodiments of this application, based on the foregoing scheme, the receiving cavity includes:

[0082] A storage cavity for storing the cleaning components;

[0083] The dust collection chamber is used to store dust from the cleaning equipment;

[0084] Wherein, along the height direction of the device body, the storage cavity is located above the dust collection cavity; the cleaning system has a non-connected state, in which the cleaning equipment is separated from the cleaning equipment auxiliary device, and the center of gravity of the cleaning equipment auxiliary device is located in the dust collection cavity.

[0085] By positioning the storage chamber above the dust collection chamber, and ensuring that the center of gravity of the cleaning equipment auxiliary device is located within the dust collection chamber when not docked, the cleaning equipment auxiliary device can maintain a low and concentrated center of gravity distribution when placed alone, thereby improving the independent placement stability of the cleaning equipment auxiliary device itself.

[0086] In some example embodiments of this application, based on the foregoing scheme, the change in position of the center of gravity of the cleaning system in the docked state compared to the change in position of the center of gravity of the cleaning system in the non-docked state along the height direction is less than a first preset value, and the change in position of the orthographic projection on the plane perpendicular to the height direction is less than a second preset value.

[0087] By limiting the change in the height of the cleaning system's center of gravity in the docked state to less than a first preset value, and the change in the orthographic projection position on the plane perpendicular to the height direction to less than a second preset value, the magnitude of the change in the center of gravity of the cleaning system before and after docking can be controlled, thereby reducing the sudden change in the center of gravity caused by the docking action and improving the stability during and after docking.

[0088] In some example embodiments of this application, based on the foregoing scheme, the first preset value is less than or equal to 30 mm; and / or

[0089] The second preset value is less than or equal to 160mm.

[0090] By limiting the first preset value to less than or equal to 30 mm, and / or limiting the second preset value to less than or equal to 160 mm, the allowable range of center of gravity change of the cleaning system before and after docking can be further clarified, thereby giving stability control a clearer quantitative boundary and further improving the reliability of the automatic dust collection process.

[0091] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0108] Although this application uses relative terms such as "up" and "down" to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as the orientation of the example shown in the accompanying drawings. It is understood that if the icon's arrangement is flipped so that it is upside down, the component described as "up" will become the component described as "down". Other relative terms, such as "high", "low", "top", "bottom", "front", "back", "left", and "right", also have similar meanings. When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0109] In this application, the terms “a,” “an,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “comprising,” “including,” and “having” are used to indicate an open-ended inclusion meaning and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0110] According to one aspect of this application, a cleaning equipment auxiliary device 200 is provided. The cleaning equipment auxiliary device 200 can be a base station, storage station, or dust collection station for docking with a handheld cleaning device 110, used for parking and supporting the cleaning device 110, transferring dust, and storing the cleaning components 114 after the cleaning device 110 is returned. The cleaning device 110 can be a vacuum cleaner, a mite remover, a handheld cleaning machine, or other cleaning equipment 110 with a dust cup 111 structure. The cleaning device 110 typically includes a dust cup 111 for collecting dust and impurities sucked in during the cleaning process; in some optional embodiments, the cleaning device 110 may also include components such as a main unit, a battery 112, an extension tube, a brush head, a crevice nozzle, and a bristle brush head.

[0111] In some implementations, reference Figure 1 and Figure 2 As shown, the cleaning equipment auxiliary device 200 includes a device body 210, on which a receiving cavity 211 and a cleaning equipment docking cavity 212 are formed. The receiving cavity 211 is used to receive and contain dust from the cleaning equipment 110 and to store the cleaning parts 114. The receiving cavity 211 can simultaneously receive and contain dust and store the cleaning parts 114. It may also include a dust collection cavity 2112 and a storage cavity 2111. The dust collection cavity 2112 is used to store dust from the cleaning equipment 110, and the storage cavity 2111 is used to store the cleaning parts 114. Along the height direction of the device body 210, the dust collection cavity 2112 and the storage cavity 2111 are arranged at intervals. Here, the interval arrangement can be understood as the two being arranged separately from each other in the height direction. It can be that the dust collection cavity 2112 is located below the storage cavity 2111 and the storage cavity 2111 is located above the dust collection cavity 2112. It can also be arranged in other upper and lower layers according to the overall shape of the machine and the internal flow channel requirements. By stratifying the dust collection chamber 2112 and the storage chamber 2111 along the height direction, it is beneficial to functionally divide the dust storage area and the cleaning component 114 storage area, making the internal structure of the device body 210 clearer and facilitating the spatial arrangement of different functional areas.

[0112] refer to Figure 3As shown, a dust collection motor 213 is also provided inside the device body 210. The dust collection motor 213 is used to generate negative pressure during operation to drive the dust self-cleaning device 110 to transfer to the dust collection chamber 2112. The dust collection motor 213 can be a centrifugal fan assembly, an axial fan assembly, or other motor assembly capable of generating suction negative pressure. In some embodiments, the dust collection motor 213 can be located in the lower middle region of the device body 210 to take into account the overall mass distribution of the device body 210 and the length of the dust collection path; in other embodiments, the dust collection motor 213 can also be located on the side close to the receiving chamber 211 and connected to the receiving chamber 211 through a flow guiding structure. The dust collection motor 213 is provided inside the device body 210, which allows the negative pressure source and the receiving chamber 211 to form a relatively integrated structural relationship, thereby facilitating the realization of automatic dust collection function within a limited external dimension.

[0113] refer to Figure 4 As shown, the cleaning equipment auxiliary device 200 is in a docking state. In the docking state, at least a portion of the cleaning equipment 110 is located in the cleaning equipment docking cavity 212, so that the dust cup 111 of the cleaning equipment 110 is in fluid communication with the receiving cavity 211 via the cleaning equipment docking cavity 212. Here, "at least a portion" can be understood as the dust cup 111 of the cleaning equipment 110, a part of the main housing, a part of the connecting part, or a partial structure connected to the dust cup 111 entering the cleaning equipment docking cavity 212 to establish a corresponding docking relationship.

[0114] When the dust collection motor 213 starts, a negative pressure is created inside the receiving cavity 211, thereby drawing dust from the dust cup 111 of the cleaning device 110 into the receiving cavity 211. That is, in this embodiment, the cleaning device docking cavity 212 can be understood as a transition space establishing a dust collection path between the cleaning device 110 and the device body 210. This transition space serves two purposes: firstly, to accommodate the insertion or hanging of the cleaning device 110, and secondly, to establish a connection between the dust cup 111 and the receiving cavity 211. Therefore, after the cleaning device 110 returns, it does not require separate disassembly and cleaning; dust transfer can be completed in the docked state, thus improving convenience during use and consistency of the dust collection process.

[0115] Further, refer to Figure 1As shown, the orthographic projection of the center of gravity of the cleaning device 110 onto a plane perpendicular to its height lies within the orthographic projection range of the dust collection motor 213 onto that plane. This can be understood as follows: when the cleaning device 110 docks with the auxiliary cleaning device 200, the main mass center area of ​​the cleaning device 110 in the horizontal direction corresponds to the area where the dust collection motor 213 is located. Since the dust collection motor 213 is typically one of the heavier components inside the device body 210, placing the orthographic projection of the cleaning device 110's center of gravity onto that plane within the orthographic projection range of the dust collection motor 213 on that plane helps to concentrate the overall force between the cleaning device 110 and the auxiliary cleaning device 200 during docking, reducing the tendency of the cleaning device 110 to be overloaded relative to the device body 210. Thus, when the cleaning device 110 is placed on the auxiliary cleaning device 200 and performs automatic dust collection, it not only avoids significant forward tilting, lateral deviation, or excessive localized force after docking, but also helps to improve stability during docking, thereby enhancing the reliability of the automatic dust collection process.

[0116] In one feasible solution, the cleaning equipment docking cavity 212 can be configured as an insertable cavity with an opening at the front of the device body 210, allowing the cleaning equipment 110 to be inserted and docked in the front-to-back direction; or it can be configured as a downward insertion cavity with an opening at the top of the device body 210, allowing the cleaning equipment 110 to enter the docking state in the vertical direction. The receiving cavity 211 can be composed of independent chambers, or it can be a single cavity divided by a partition to form a dust collection cavity 2112 and a storage cavity 2111. The dust collection cavity 2112 can adopt a detachable dust bag structure, a flip-up dust collection box structure, or a fixed dust receiving structure; the storage cavity 2111 can be used to place cleaning parts 114 such as crevice nozzles, brush heads, and extension connectors. The dust collection motor 213 can be connected to the receiving cavity 211 through a short straight air duct or through a bent guide channel. The cleaning equipment 110 and the cleaning equipment docking cavity 212 can be docked using methods such as plugging, hooking, snapping, or magnetic assisted positioning.

[0117] In some example embodiments of this application, the orthographic projection of the dust collection motor 213 toward the dust collection chamber 2112 is within the orthographic projection range of the dust collection chamber 2112 itself; and / or, the orthographic projection of the dust collection motor 213 toward the receiving chamber 2111 is within the orthographic projection range of the receiving chamber 2111 itself.

[0118] Here, the orthographic projection toward the dust collection chamber 2112 or the orthographic projection toward the storage chamber 2111 can be understood as: when viewed along the height direction of the device body 210, the orthographic projection of the dust collection motor 213 in the height direction; correspondingly, the orthographic projection range of the dust collection chamber 2112 itself and the orthographic projection range of the storage chamber 2111 itself can be understood as the orthographic projection range of the outline of the dust collection chamber 2112 and the storage chamber 2111 in the height direction when viewed along the height direction.

[0119] In some embodiments, the orthographic projection of the dust collection motor 213 can fall within the orthographic projection range of the dust collection chamber 2112, so that the dust collection motor 213 and the dust collection chamber 2112 are arranged correspondingly in height. In other embodiments, the orthographic projection of the dust collection motor 213 can also fall within the orthographic projection range of the housing chamber 2111, so that the dust collection motor 213 and the housing chamber 2111 are arranged correspondingly in planar position. Of course, in some embodiments, the dust collection motor 213 can also satisfy both of the above-mentioned orthographic projection relationships at the same time.

[0120] Therefore, the dust collection motor 213 and the dust collection chamber 2112 and / or the storage chamber 2111 can form a relatively concentrated spatial arrangement within the device body 210, which is conducive to improving the utilization rate of the internal space of the device body 210. Secondly, it is also conducive to bringing the weight area corresponding to the dust collection motor 213 and the corresponding area of ​​the storage chamber 211 closer to each other, which is conducive to improving the overall stability of the cleaning equipment auxiliary device 200 in the docking state.

[0121] To further balance the integration of internal space and optimization of mass distribution within the receiving cavity 211, according to an exemplary embodiment of this application, the receiving cavity 2111 is located above the dust collection cavity 2112 along the height direction, and the orthographic projection of the receiving cavity 2111 onto the plane is at least partially within the orthographic projection range of the dust collection cavity 2112 onto the plane; or, refer to Figure 7 As shown, along the height direction, the dust collection chamber 2112 is located above the storage chamber 2111, and the orthographic projection of the dust collection chamber 2112 on the plane is within the orthographic projection range of the storage chamber 2111 on the plane.

[0122] Here, "plane" can be understood as a plane perpendicular to the height direction, that is... Figure 1 The horizontal plane a in the middle; the orthographic projection of the receiving cavity 2111 on the plane is at least partially within the orthographic projection range of the dust collection cavity 2112 on the plane, which can be understood as the orthographic projection of the outline of the receiving cavity 2111 and the orthographic projection of the outline of the dust collection cavity 2112 at least partially overlap from the top view; correspondingly, the orthographic projection of the dust collection cavity 2112 on the plane is within the orthographic projection range of the receiving cavity 2111 on the plane, which can be understood as the orthographic projection of the outline of the dust collection cavity 2112 falling within the orthographic projection range of the outline of the receiving cavity 2111 from the top view.

[0123] The receiving cavity 2111 can be arranged above the dust collection cavity 2112 and partially correspond to the dust collection cavity 2112 in planar position, so as to form a layered cavity structure without significantly increasing the lateral dimension of the device body 210. In other embodiments, the dust collection cavity 2112 can also be arranged above the receiving cavity 2111, and the receiving cavity 2111 forms an enclosing correspondence with the dust collection cavity 2112 in planar position. This application does not impose specific restrictions on the specific overlap ratio between the receiving cavity 2111 and the dust collection cavity 2112, as long as the above-mentioned orthographic projection relationship is satisfied. Thus, the dust collection cavity 2112 and the receiving cavity 2111 can form a relatively compact vertically corresponding arrangement within the device body 210, which is beneficial to improving the space utilization of the receiving cavity 211; secondly, it is also beneficial to make the weight area inside the device body 210 more concentrated in the planar direction, which is beneficial to improving the stability of the cleaning equipment auxiliary device 200 in the docking state.

[0124] To ensure that the dust collection motor 213 is installed in a way that accommodates both the dust collection chamber 2112 and the receiving chamber 2111, and to further optimize the spatial layout and mass concentration within the device body 210, according to an exemplary embodiment of this application, the orthographic projection of the dust collection motor 213 on the plane is at least partially located within the orthographic projection range of the receiving chamber 2111 on the plane, and at least partially located within the orthographic projection range of the dust collection chamber 2112 on the plane. In other words, when viewed along the height direction, the planar position corresponding to the dust collection motor 213 corresponds simultaneously to both the receiving chamber 2111 and the dust collection chamber 2112.

[0125] To reduce the interference of the docking structure of the cleaning equipment 110 on the internal arrangement of the receiving cavity 211, and to take into account the mass distribution in the docking state, according to an exemplary embodiment of this application, the cleaning equipment docking cavity 212 is located between the top and bottom ends of the device body 210 along the height direction, and is disposed close to the top end. Furthermore, the orthographic projection of the cleaning equipment docking cavity 212 toward the receiving cavity 211 does not fall within the orthographic projection range of the receiving cavity 211. That is, the cleaning equipment docking cavity 212 is offset from the receiving cavity 211 in planar position, rather than directly overlapping it vertically.

[0126] In some embodiments, the cleaning equipment docking cavity 212 can be located on the upper front or upper rear side of the device body 210; in other embodiments, the cleaning equipment docking cavity 212 can also be located on the upper side of the device body 210, as long as it does not directly correspond to the receiving cavity 211 on the plane. This application does not impose specific limitations on the specific misalignment distance between the cleaning equipment docking cavity 212 and the receiving cavity 211.

[0127] Therefore, it can not only avoid the docking structure occupying too much space inside the receiving cavity 211, but also facilitate the reasonable arrangement of the dust collection cavity 2112, the storage cavity 2111 and the dust collection motor 213; secondly, it can also help optimize the overall mass distribution between the device body 210 and the cleaning equipment 110 in the docking state, thereby improving the docking stability.

[0128] In one possible implementation, the cleaning equipment docking cavity 212 may be disposed adjacent to the upper front side of the device body 210; or, the cleaning equipment docking cavity 212 and the receiving cavity 211 may be separated by a partition; or, a gap may be left between the orthographic projection of the cleaning equipment docking cavity 212 on the plane and the orthographic projection of the receiving cavity 211.

[0129] In some example embodiments of this application, reference is made to Figure 4 As shown, the device body 210 has a motor exhaust port 219, which is located below the receiving cavity 211 along the height direction; and the dust collection motor 213 is located close to the motor exhaust port 219. This can be understood as the exhaust path formed by the dust collection motor 213 during operation being discharged towards the lower position of the device body 210, and the distance between the dust collection motor 213 and the motor exhaust port 219 being relatively close.

[0130] The above configuration shortens the exhaust path between the dust collection motor 213 and the motor exhaust port 219, thereby reducing resistance loss during exhaust flow and improving exhaust smoothness. Furthermore, the motor exhaust port 219 being located below the receiving cavity 211 allows for a clearer upper and lower partitioning of the exhaust area from the dust collection cavity 2112 and the storage cavity 2111, thus helping to reduce the impact of exhaust on the contents and dust collection area within the receiving cavity 211.

[0131] In one possible implementation, the motor exhaust port 219 may be located on the front, rear or bottom side of the lower part of the device body 210; or, the dust collection motor 213 may be directly connected to the motor exhaust port 219 through an air duct.

[0132] To optimize the exhaust path of the dust collection motor 213 and to balance the utilization of internal space and the uniformity of exhaust, according to one exemplary embodiment of this application, the motor exhaust ports 219 can be designed in multiple sets. These multiple sets of motor exhaust ports 219 can be arranged at circumferential intervals around the device body 210, either at equal or unequal intervals, to adapt to the structural layout requirements of different areas of the device body 210.

[0133] Based on this, each group of motor exhaust ports 219 can be one or more; when there are multiple motor exhaust ports 219, they can be spaced apart along the height direction. Alternatively, there can be multiple motor exhaust ports 219, spaced apart along the height direction; similarly, the spacing can be equal or unequal. The position and number of motor exhaust ports 219 can be adjusted according to the distribution of internal components of the device body 210, and this application does not impose specific limitations. Thus, a dispersed exhaust area can be formed on the device body 210, thereby improving the ventilation of the dust collection motor 213.

[0134] In addition, this application does not specifically limit the shape and arrangement of the motor exhaust port 219. For example, the motor exhaust port 219 can be configured as a strip hole array, a round hole array or an oblong hole array.

[0135] To facilitate the separate opening of the dust collection chamber 2112 and the storage chamber 2111, while also ensuring the neatness of the appearance and the consistency of the structural layout of the device body 210, according to an exemplary embodiment of this application, refer to... Figure 5 As shown, the dust collection chamber 2112 includes a dust collection chamber cover 220, which is pivotable along the pivot axis L1 of the device body 210 to open or close the dust collection chamber 2112; and / or, the storage chamber 2111 includes a storage chamber cover 221, which is pivotable along the pivot axis L2 of the device body 210 to open or close the storage chamber 2111, wherein the pivot axis L1 and the pivot axis L2 are collinear in the height direction.

[0136] In another example embodiment, when the dust collection chamber cover 220 closes the dust collection chamber 2112, the dust collection chamber cover 220 has a cover line M1; when the storage chamber cover 221 closes the storage chamber 2111, the storage chamber cover 221 has a cover line M2, wherein the cover line M1 and the cover line M2 are collinear along the height direction.

[0137] In some embodiments, the dust collection chamber cover 220 and the storage chamber cover 221 can be separate flip-tops, each capable of rotating around an independent axis, but the two axes are aligned in the height direction. In other embodiments, the dust collection chamber cover 220 and the storage chamber cover 221 can also be located on the front or side wall of the device body 210, as long as their pivot axes are collinear in the height direction. Furthermore, the opening directions of the dust collection chamber cover 220 and the storage chamber cover 221 can be the same or opposite; the cover-fitting lines M1 and M2 can be straight lines or spliced ​​lines composed of multiple line segments, and this application does not impose specific limitations on this.

[0138] This application does not specifically limit the rotation method of the dust collection chamber cover 220 and the storage chamber cover 221. For example, in some embodiments, the dust collection chamber cover 220 and the dust collection chamber 2112 can be connected by hinges, and the storage chamber cover 221 and the storage chamber 2111 can be connected by hinges. The dust collection chamber cover 220 and the storage chamber cover 221 can adopt a shared hinge or independent hinges distributed along the same straight line.

[0139] This facilitates the formation of a vertical correspondence between the dust collection chamber 2112 and the storage chamber 2111 in terms of their opening and closing structures, thereby enabling a unified design of the overall appearance and structural components of the device body 210. Secondly, it also helps improve the user's ability to identify the opening positions of different chambers.

[0140] To facilitate stable support of the dust collection motor 213 and maintain a predetermined orthographic projection correspondence, in some example embodiments of this application, a fixing bracket (not shown) is also provided within the device body 210. This fixing bracket can be a structural component used to support, limit, and install the dust collection motor 213. Its function is not only to install the dust collection motor 213 but also to position the dust collection motor 213 to a target position corresponding to the dust collection chamber 2112 and / or the receiving chamber 2111. The fixing bracket can be a plate-shaped bracket, a frame-type bracket, or a ribbed bracket; the fixing bracket can be integrally formed with the device body 210 or can be a separate mounting component. The fixing bracket can be connected to the device body 210 by screwing, snap-fitting, welding, or embedding. The fixed bracket supports and fixes the dust collection motor 213 so that the orthographic projection of the dust collection motor 213 toward the dust collection chamber 2112 is within the orthographic projection range of the dust collection chamber 2112 itself; and / or, so that the orthographic projection of the dust collection motor 213 toward the receiving chamber 2111 is within the orthographic projection range of the receiving chamber 2111 itself.

[0141] By setting up a fixed bracket, the accuracy and stability of the installation position of the dust collection motor 213 can be improved, which helps to ensure the feasibility of the aforementioned orthographic projection relationship in actual assembly. Secondly, after the fixed bracket positions the dust collection motor 213 in the predetermined area, it can further stabilize the position of the larger mass components inside the device body 210, thereby helping to ensure the consistency of the overall center of gravity distribution in the docking state.

[0142] To facilitate the categorization, storage, and stable positioning of the cleaning components 114, in some example embodiments of this application, the storage cavity 2111 is provided with at least one storage section, and the cleaning components 114 are detachably connected to the storage section. The storage section includes at least two storage positions, which are used to limit and / or detachably fix the ends of at least two cleaning components 114. That is, the storage cavity 2111 is not merely used as an empty cavity, but is further provided with specific structures inside for receiving and positioning the cleaning components 114 to accommodate the placement of multiple cleaning components 114. The storage section can be a connector, a clip, a hanger, a clamp, or a magnetic fixing structure; the storage positions can be slots, buckles, hooks, elastic clamps, or magnetic positioning parts; or, different storage positions can correspond to different types of cleaning components 114.

[0143] At least two storage positions can be arranged along the height direction, or along the width direction or the front-to-back direction. This arrangement allows different cleaning components 114 to have relatively clear storage locations within the storage cavity 2111, thereby improving the orderliness of storage and ease of retrieval. Furthermore, the at least two storage positions respectively limit and / or detachably fix the ends of at least two cleaning components 114, which can also reduce the possibility of shaking, collision, or misalignment of the cleaning components 114 during device movement or docking, thus helping to maintain the stability of the storage cavity 2111.

[0144] In some example embodiments of this application, reference is made to Figure 3 and Figure 6As shown, the dust collection chamber 2112 includes a dust inlet connecting to the dust cup docking chamber 2122. The dust cup docking chamber 2122 has a dust collection port 215. The device body 210 also has a dust collection pipe 218, which connects the dust inlet and the dust collection port 215. That is, when the cleaning device 110 is in the docking state, the dust collection port 215 on one side of the dust cup docking chamber 2122 corresponds to the dust outlet path of the dust cup 111 of the cleaning device 110, while the dust inlet on one side of the dust collection chamber 2112 is used to guide dust into the dust collection chamber 2112. The two form a relatively clear dust guiding path through the dust collection pipe 218. The dust collection pipe 218 can be a straight pipe, a bent pipe, or a segmented connecting pipe; the cross-section of the dust collection pipe 218 can be circular, elliptical, rectangular, or other shapes suitable for flow guidance; alternatively, the inner wall of the dust collection pipe 218 can be set as a smooth flow guiding surface; furthermore, the dust collection port 215 and the dust inlet can be connected to the dust collection pipe 218 respectively through a sealed connection structure. This arrangement allows dust from the dust cup 111 of the cleaning equipment 110 to enter the dust collection chamber 2112 along a predetermined path, thereby reducing the possibility of disorderly diffusion of dust inside the device body 210. Furthermore, after the dust collection port 215, the dust collection pipe 218, and the dust inlet form relatively independent flow paths, the flow guidance stability during the automatic dust collection process can be improved, thus contributing to the improvement of the reliability of automatic dust collection.

[0145] To further define the positional relationship between the cleaning device 110 and the dust collection motor 213 in the docking state, and to balance docking stability and automatic dust collection reliability, in some example embodiments of this application, reference is made to... Figure 5 As shown, the dust collection motor 213 has a motor rotation axis L3. In the docked state, the distance between the orthographic projection of the center of gravity of the cleaning device 110 on a plane perpendicular to the height direction and the orthographic projection of the motor rotation axis L3 on the plane is less than a first preset distance d1. The first preset distance d1 can be determined by the outer diameter of the dust collection motor 213, the width of the device body 210, or the overall dimensions of the cleaning device 110; or, the first preset distance d1 can be set to no more than half of the maximum outer dimension of the dust collection motor 213.

[0146] In some example implementations, the first preset distance d1 is less than or equal to 30mm, for example, it can be 30mm, 25mm, 22mm, 20mm, 18mm, 15mm, 10mm, etc.; or, it can be selected within the range of 0-30mm depending on the different models of cleaning equipment 110.

[0147] With the above settings, the center of gravity of the cleaning device 110 and the center of the dust collection motor 213 can be closer on the plane, which helps to concentrate the main mass distribution in the same area during docking. Secondly, after the distance between the orthographic projection of the center of gravity and the orthographic projection of the motor rotation axis L3 is constrained, the off-center load caused by excessive offset can also be reduced, which in turn helps to improve the stability of docking and parking.

[0148] In order to further consider the impact of auxiliary components on the overall mass distribution when the cleaning component 114 is housed in the storage cavity 2111, in some example embodiments of this application, reference is made to... Figure 6 As shown, the cleaning system 100 includes a cleaning component 114; when the cleaning component 114 is located in the storage cavity 2111, the extension line of the center of gravity of the cleaning device 110 has a second preset distance d2 with the rotation axis L3 of the motor, and the second preset distance d2 is less than or equal to the first preset distance d1.

[0149] This can be understood as follows: when the cleaning component 114 is stored together, the extension line of the center of gravity of the cleaning device 110 still maintains a small deviation from the corresponding position of the center of the dust collection motor 213. In some embodiments, the second preset distance d2 can be equal to or less than the first preset distance d1; the second preset distance d2 can be determined in combination with the number, mass, and storage position of the cleaning component 114. This helps to reduce the adverse effects of storing the cleaning component 114 on the overall center of gravity relationship, thereby enabling the cleaning system 100 to maintain a relatively close mass distribution characteristic under different usage states; secondly, it also helps to maintain the stability of the docking state. Furthermore, the fact that the second preset distance d2 is less than or equal to the first preset distance d1 also indicates that the mass change after storing the cleaning component 114 is still controlled within a predetermined range, which helps to maintain the stability of the center of gravity of the cleaning equipment auxiliary device 200 under different usage states.

[0150] In some example embodiments of this application, the dust cup docking cavity 2122 includes a docking surface, which may be a flat surface, an arc surface, or a support surface with a buffer layer; alternatively, the docking surface may be provided with positioning protrusions, elastic pads, or a low-friction layer. (See reference) Figure 5As shown, in the docking state, the outer wall surface of the dust cup 111 abuts against the docking surface. In the height direction, the horizontal distance between the docking surface and the central axis L4 of the dust cup 111 is a third preset distance d3, which is less than or equal to 60mm. For example, it can be 60mm, 55mm, 50mm, 40mm, 30mm, 20mm, etc., or any number between 0 and 60. Thus, the dust cup 111 is not suspended during docking, but rather its outer wall surface forms a support or limiting relationship with the docking surface, and the position of the docking surface relative to the central axis L4 of the dust cup 111 is limited within a certain range. This makes the positioning of the dust cup 111 within the dust cup docking cavity 2122 more precise, thereby helping to reduce the shaking of the dust cup 111 in the docking state.

[0151] Furthermore, a third preset distance d3 less than or equal to 60mm allows the supporting position of the mating surface on the dust cup 111 to remain closer to the central axis L4 of the dust cup 111, thereby helping to reduce the additional overturning moment caused by eccentric support and improve stability in the mating state. It is understood that the third preset distance d3 can be interpreted as the radius of the dust cup 111, and those skilled in the art can adjust the third preset distance d3 according to the radius of the dust cup 111; this application does not impose specific limitations on this adjustment.

[0152] In some embodiments, the volume of the dust cup 111 can be 0.54L. Compared to a larger volume dust cup 111, such as a 0.76L dust cup 111, a 0.54L dust cup 111, while meeting usage requirements, can form a relatively shorter structural dimension in the axial direction of the dust cup 111, that is, the height of the dust cup 111 is shorter. Due to the reduced dimension of the dust cup 111 in the height direction, the arrangement of the dust cup docking cavity 2122 in the device body 210 has a higher degree of freedom, the docking surface can be set closer to the central axis region of the device body 210, and the lateral distance of the dust cup central axis L4 relative to the central axis of the device body 210 can also be reduced accordingly.

[0153] Furthermore, in the docked state, the dust cup 111, as one of the main structural components during docking, has a significant impact on the overall center of gravity of the machine. When the dust cup 111 is shortened axially and recessed towards the central axis of the device body 210, it avoids excessive lateral offset of the cleaning device 110 relative to the central axis of the device body in the docked state due to the excessive size of the dust cup 111. Consequently, the center of gravity of the cleaning device 110 is more likely to move towards the area where the dust collection motor 213 is located, which is more conducive to ensuring that the orthographic projection of the center of gravity of the cleaning device 110 on the plane perpendicular to the height direction is within the orthographic projection range of the dust collection motor 213 on that plane, thereby improving the stability of docking and parking and enhancing the reliability of the automatic dust collection process.

[0154] According to the second aspect of this application, reference is made to Figures 4 to 7 As shown, a cleaning system 100 is provided. The cleaning system 100 may include a cleaning device 110 and a cleaning device auxiliary device 200.

[0155] The cleaning device 110 can be a handheld vacuum cleaner, a handheld unit of an upright vacuum cleaner, a mite remover unit, or other cleaning devices 110 with a dust cup 111 and a battery 112; the cleaning device 110 includes a dust cup 111 and a battery 112, the battery 112 is connected to a power receiving interface, and the dust cup 111 includes a dust cup cover 1112.

[0156] The cleaning equipment auxiliary device 200 can be a base station, a floor-standing storage base, a dust collection and charging base, or an auxiliary device with automatic dust collection function. The cleaning equipment auxiliary device 200 includes a device body 210 and a dust collection motor 213. The device body 210 has a receiving cavity 211 and a cleaning equipment docking cavity 212. The receiving cavity 211 includes a dust collection cavity 2112 and a storage cavity 2111. The dust collection cavity 2112 is used to store dust from the cleaning equipment 110, and the storage cavity 2111 is used to store the cleaning component 114.

[0157] Here, the cleaning component 114 can be a crevice tool, brush, crevice tool, extension rod, hose, or other detachable accessories. The cleaning equipment docking chamber 212 includes a battery docking chamber 2121 and a dust cup docking chamber 2122. The dust collection motor 213 is located inside the device body 210, the charging interface 214 is located inside the battery docking chamber 2121, and the dust collection port 215 is located in the dust cup docking chamber 2122. Along the height direction of the device body 210, the dust collection chamber 2112 and the storage chamber 2111 are spaced apart to form relatively independent dust collection areas and accessory storage areas inside the device body 210.

[0158] In some embodiments, the battery docking cavity 2121 and the dust cup docking cavity 2122 can be arranged vertically along the height direction, for example, the battery docking cavity 2121 is located above the dust cup docking cavity 2122; they can also be arranged obliquely or staggered front and back, as long as the battery 112 part enters the battery docking cavity 2121 and the dust cup 111 part enters the dust cup docking cavity 2122 when the cleaning device 110 enters the docking state. The charging interface 214 can be a pin type, spring type, terminal type or magnetic conductive structure, and the power receiving interface can be set on the battery 112 shell, handle part or main body shell, corresponding to and cooperating with the charging interface 214. The dust collection port 215 can be set to correspond to the opening position of the dust cup cover 1112, or it can be set to correspond to the dust falling passage of the dust cup 111, so that the dust cup 111 and the dust collection port 215 form a dust collection communication relationship in the docking state.

[0159] The cleaning equipment auxiliary device 200 is in a docked state. In the docked state, the battery 112 is at least partially located in the battery docking cavity 2121, the charging interface 214 is electrically connected to the power receiving interface, the dust cup 111 is at least partially located in the dust cup docking cavity 2122, and the dust cup cover 1112 is aligned with the dust collection port 215. "Alignment" here can be understood as the dust cup cover 1112 being in a position that establishes a dust collection correspondence with the dust collection port 215. For example, the opening area of ​​the dust cup cover 1112 faces the dust collection port 215, or the dust path formed by the dust cup cover 1112 after opening is connected to the dust collection port 215. Furthermore, the relative positions of the battery docking cavity 2121 and the dust cup docking cavity 2122 are configured such that, in the docked state, the orthographic projection of the center of gravity of the cleaning equipment 110 on a plane perpendicular to the height direction falls within the orthographic projection range of the dust collection motor 213 on that plane. In other words, after docking, the main weight area of ​​the cleaning equipment 110 is guided to a position close to the dust collection motor 213, thereby making the mass distribution of the cleaning equipment 110 and the cleaning equipment auxiliary device 200 more concentrated in the docked state.

[0160] The dust collection motor 213 can be located between the dust collection chamber 2112 and the storage chamber 2111, or it can be located closer to the dust collection chamber 2112. The battery docking chamber 2121 can be located near the upper part of the device body 210, and the dust cup docking chamber 2122 can be located near the middle of the device body 210, so that the docked cleaning equipment 110 can form a stable support relationship with a top-light and bottom-heavy or front-light and rear-heavy orientation. Furthermore, a base or support foot can be provided at the bottom of the device body 210, and the relative positions of the dust collection motor 213, the dust collection chamber 2112, and the cleaning equipment docking chamber 212 in the horizontal direction can be arranged in conjunction with the support range of the base, which is not limited in this application.

[0161] With the above structure, the cleaning system 100 can not only achieve the functions of charging and automatic dust collection after the cleaning equipment 110 is repositioned, but also help reduce the docking off-center load problem caused by the unreasonable distribution of the battery 112 and dust cup 111, thereby improving the parking stability of the cleaning equipment 110 on the cleaning equipment auxiliary device 200; secondly, the orthographic projection of the center of gravity of the cleaning equipment 110 is located within the orthographic projection range of the dust collection motor 213, which also helps to maintain a relatively stable docking posture during the automatic dust collection process, thereby improving the reliability of automatic dust collection.

[0162] To enable the cleaning device 110 to prepare for controlled opening of the dust cup cover 1112 during docking with the cleaning device auxiliary device 200, and to restore it to a closed and safe state upon disengagement, according to an example embodiment of this application, referencing... Figure 6As shown, the cleaning system 100 can further incorporate a dust cup cover 1112 unlocking structure based on the aforementioned design. Specifically, the dust cup 111 includes a dust cup body 1111 and a dust cup cover 1112, with the dust cup cover 1112 rotatably mounted on the dust cup body 1111. Here, "rotatably mounted" can be understood as the dust cup cover 1112 being installed on the dust cup body 1111 via a pivot, hinge, pivot structure, or elastic connection structure, allowing it to rotate between a closed position and an open position relative to the dust cup body 1111. When in the closed position, the dust cup cover 1112 can seal the dust discharge opening of the dust cup 111; when in the open position, it can release the dust inside the dust cup 111.

[0163] Accordingly, refer to Figure 8 As shown, the cleaning equipment auxiliary device 200 includes an unlocking member 216, which is disposed at the dust collection port 215. Being disposed at the dust collection port 215 can be understood as the unlocking member 216 being located in the area adjacent to the dust collection port 215, in the installation area connected to the dust collection port 215, or in a position where it can interact with the unlocking part of the dust cup cover 1112 when the cleaning equipment 110 enters the docking state. It is sufficient that the unlocking action of the dust cup cover 1112 can be triggered during the movement of the cleaning equipment 110.

[0164] In some embodiments, the unlocking element 216 can be a mechanical actuating element, a pressing element, a push rod, a paddle, a protruding structure, a roller element, or a slider element; it can also be an electromagnetic drive element, a telescopic element, or a controlled actuator. The preset unlocking position can be the position when the cleaning device 110 moves to a specific travel position along the docking path, or it can be the position when the unlocking part on the dust cup cover 1112 contacts, engages with, or corresponds to the unlocking element 216. In other words, when the cleaning device 110 moves to the preset unlocking position towards the cleaning device auxiliary device 200, the unlocking element 216 triggers the dust cup cover 1112 to unlock, causing the dust cup cover 1112 to switch from a locked state to a ready-to-open state. The locked state can refer to the state in which the dust cup cover 1112 is held in a closed position by a latch, hook, lock tongue, magnetic attraction element, or other limiting structure; the ready-to-open state can refer to the state in which the dust cup cover 1112 has been unlocked, but has not yet been opened under the action of gravity, negative pressure, elastic restoring force, or external traction force. Therefore, the dust cup cover 1112 can be unlocked and prepared without any additional manual operation after docking, thus providing a foundation for subsequent dust collection.

[0165] In some embodiments, the unlocking element 216 can also be configured to release the trigger for unlocking the dust cup cover 1112 when the cleaning device 110 is disengaged from the unlocked position, causing the dust cup cover 1112 to switch from an openable state to a locked state. Disengaging from the unlocked position can be understood as the cleaning device 110 moving away in the opposite direction to the docking direction, causing the unlocking part of the dust cup cover 1112 to disengage from the unlocking element 216, or to be no longer within the unlocking trigger range. Accordingly, the dust cup cover 1112 can return to the locked state under the action of a return spring, torsion spring, gravity counterweight, magnetic component, or the restoring force of the locking mechanism. This configuration helps to prevent the dust cup cover 1112 from accidentally being in an openable state when the cleaning device 110 is not docked, thereby reducing the possibility of dust scattering during handling, handling, or daily use.

[0166] In one possible implementation, the dust cup cover 1112 may be provided with an unlocking protrusion, an unlocking lever, or a locking trigger, with the unlocking member 216 corresponding to each of these parts; alternatively, the unlocking member 216 may be located at the edge of the dust collection port 215, and the locking mechanism of the dust cup cover 1112 may be activated by the relative displacement of the dust cup body 1111 during the insertion of the cleaning device 110. Further, the unlocking member 216 may be a fixed structure, achieving mechanical triggering through a docking stroke; or it may be a movable structure, actively extending after detecting the approach of the cleaning device 110 and retracting after the cleaning device 110 leaves. A guide surface, a buffer surface, or an elastic clearance structure may also be provided to reduce the impact between the unlocking member 216 and the dust cup cover 1112, improving the smoothness of operation and durability.

[0167] In order to enable the opening and closing of the dust cup cover 1112 to cooperate with the automatic dust collection process, according to an example embodiment of this application, a negative pressure drive opening and closing structure of the reset component 117 can be further provided on the basis of the aforementioned dust cup cover 1112 unlocking scheme.

[0168] Specifically, in the docking state, the dust collection motor 213 starts to create a negative pressure airflow between the docking chamber 212 and the receiving chamber 211 of the cleaning equipment. This negative pressure airflow drives the dust cup cover 1112, which is in a waiting-to-open state, to switch to the open state. In other words, when the dust cup cover 1112 has been unlocked but not fully opened, the airflow pressure difference generated by the dust collection motor 213 can be used to directly apply an opening force to the dust cup cover 1112, thereby automatically opening the dust cup cover 1112. The negative pressure airflow can be understood as a directional flow of airflow formed by the suction of the dust collection motor 213 between the docking chamber 212, the dust collection port 215, the dust collection pipe, and the receiving chamber 211 of the cleaning equipment. The driving force can be either directly suctioning and pulling the dust cup cover 1112, or acting on the pressure difference structure near the dust release channel inside the dust cup 111, thereby indirectly driving the dust cup cover 1112 to rotate and open.

[0169] In some embodiments, when the dust cup cover 1112 is in the openable state, it may have already disengaged from the locking constraint and retain a certain degree of freedom to open. At this time, as long as the negative pressure airflow generated after the dust collection motor 213 starts reaches the preset operating conditions, the dust cup cover 1112 can switch from the openable state to the open state under the action of pressure difference. In this way, the opening action of the dust cup cover 1112 does not need to rely on an additional independent driving component, but can be realized in conjunction with the starting action of the dust collection motor 213. Furthermore, the position of the negative pressure airflow can be located in the area adjacent to the dust cup cover 1112, at the dust discharge opening of the dust cup 111, or on the side of the dust cup cover 1112 away from the pivot axis, so as to form a torque more conducive to opening. Correspondingly, the size, rotational damping, and counterweight structure of the dust cup cover 1112 can also be designed to match the negative pressure opening requirements, and this application does not impose specific limitations on this.

[0170] Further, refer to Figure 6 As shown, the cleaning device 110 includes a reset member 117, which connects the dust cup cover 1112 and the dust cup body 1111. This connection can be direct or formed through a connecting seat, mounting lug, rotating shaft, or transition piece. The reset member 117 can be a torsion spring, tension spring, compression spring, elastic sheet, elastic arm, or other structural component capable of providing restoring force. The reset member 117 is configured to drive the dust cup cover 1112 from the open state to the ready-to-open state after the dust collection motor 213 stops operating. That is, when the dust collection motor 213 stops working and the negative pressure airflow weakens or disappears, the reset member 117 outputs a restoring force, causing the dust cup cover 1112 to rotate from the open position to the ready-to-open position, instead of directly returning to the locked state. This design, on the one hand, avoids the dust cup cover 1112 repeatedly swinging due to airflow fluctuations during dust collection, and on the other hand, provides a transitional action for re-entering the locked state when subsequently released from the unlocked position.

[0171] In one possible implementation, the reset member 117 can be located at the pivot axis of the dust cup cover 1112, providing rotational restoring force in the form of a torsion spring; alternatively, it can be located on the side between the dust cup cover 1112 and the dust cup body 1111, pulling the dust cup cover 1112 back to its original position in the form of a tension spring or a leaf spring. Further, the restoring force of the reset member 117 can be less than the opening force of the negative pressure airflow on the dust cup cover 1112 but greater than the component of the dust cup cover 1112's own weight in the opening direction, so that the dust cup cover 1112 can reliably open when the dust collection motor 213 is running, and automatically return to the ready-to-open state after the dust collection motor 213 stops running. A buffer structure, a limiting structure, or a damping structure can also be provided to limit the maximum opening angle of the dust cup cover 1112, reduce return impact, and improve structural life and operational stability.

[0172] According to an exemplary embodiment of this application, reference is made to... Figure 5 As shown, the cleaning device 110 also includes a suction pipe 115, which connects to the dust cup 111. The suction pipe 115 has a central axis L5. Based on this, the positional relationship between the central axis L4 of the dust cup 111, the central axis L5 of the suction pipe, and the motor rotation axis L3 is defined. Specifically, the dust cup 111 has a central axis L4, and the dust collection motor 213 has a motor rotation axis L3. The central axis L4 of the dust cup 111 is the axis along the length, volume extension direction, or the center extension direction of the main body contour of the dust cup body 1111; the motor rotation axis L3 is the rotation center line of the rotor or impeller inside the dust collection motor 213. In the docked state, the central axis L4 of the dust cup 111 and the motor rotation axis L3 are basically perpendicular. Here, "basically perpendicular" can be understood as the angle between them being close to 90°. For example, certain assembly errors, structural avoidance errors, or flow angle adjustments can be allowed, as long as the overall arrangement forms a horizontally intersecting relationship.

[0173] In other embodiments, the central axis L4 of the dust cup 111 and the central axis L5 of the suction pipe jointly define a first plane, and the motor rotation axis L3 is parallel to the first plane. The first plane that jointly defines the first plane means that the central axis L4 of the dust cup 111 and the central axis L5 of the suction pipe are in the same geometric plane, or a reference plane that can characterize the overall extension trend of the dust cup 111 and the suction pipe 115 in an engineering sense; the motor rotation axis L3 being parallel to the first plane can be understood as the motor rotation axis L3 maintaining a parallel relationship with the plane, or although there may be a small range of assembly deviations, it does not deviate from the overall intention of parallel arrangement of the plane.

[0174] In one possible implementation, the dust cup 111 can be a horizontally arranged cylindrical dust cup 111, in which case the central axis L4 of the dust cup 111 extends in the left-right direction, and the dust collection motor 213 can be located on the rear or lower side of the device body 210, so that the motor rotation axis L3 extends in the front-back direction or the left-right direction, thereby forming a basically perpendicular relationship with the central axis L4 of the dust cup 111. Alternatively, the suction pipe 115 extends longitudinally along the cleaning device 110 and connects to the dust cup 111, with the central axis L4 of the dust cup 111 and the central axis L5 of the suction pipe forming a side view plane or a top view plane, and the dust collection motor 213 is arranged with its rotation axis close to this plane.

[0175] Furthermore, the vertical distance between the motor rotation axis L3 and the first plane is less than or equal to 10mm, for example, it can be 0mm, 2mm, 5mm, 8mm or 10mm, and can also be adjusted according to the internal structure of the device body 210, the direction of the dust collection air duct and the thickness of the support structure. This application does not impose specific restrictions on this.

[0176] With the above settings, when the central axis L4 of the dust cup 111 is basically perpendicular to the rotation axis L3 of the motor, it is beneficial to form a more compact cross arrangement in the docking state, thereby providing a more flexible layout basis for the docking area of ​​the cleaning equipment 110, the installation area of ​​the dust collection motor 213, and the internal space of the receiving cavity 211. Secondly, when the rotation axis L3 of the motor is parallel to the first plane and the vertical distance between it and the first plane is less than or equal to 10mm, the axial position of the dust collection motor 213 can be closer to the main structural distribution represented by the dust cup 111 and the suction pipe 115 in the cleaning equipment 110, thereby helping to optimize the mass distribution of the cleaning equipment 110 in the docking state and improve the coordination stability during the automatic dust collection process.

[0177] To further optimize the center of gravity position in the docking state by utilizing the weight distribution of the cleaning equipment 110's own components, according to an example embodiment of this application, referencing... Figure 4 and Figure 6 As shown, the cleaning device 110 may include a main motor 116, which is located at the end of the dust cup 111 away from the dust cup cover 1112. This can be understood as the end with the dust cup cover 1112 being the dust discharge or opening end, and the main motor 116 being arranged on the side of the dust cup 111 opposite to this opening end, thus placing the main motor 116 in a relatively rearward region within the main body of the cleaning device 110. The main motor 116 can be a fan motor driving the suction airflow or the main suction motor of the cleaning device 110, and its weight is typically greater than that of general functional components. Meanwhile, in the docked state, the battery 112 is located above the dust cup 111, meaning the battery 112 is at a higher position relative to the dust cup 111, while the main motor 116 is at the other end relative to the dust cup 111. Through the spatial arrangement of the main motor 116 and the battery 112, a predetermined mass distribution relationship can be achieved after the cleaning device 110 is inserted into the cleaning device auxiliary device 200.

[0178] Furthermore, the weight of the main motor 116 is greater than the weight of the battery 112, so that the center of gravity of the cleaning device 110 in the docked state is biased towards the dust collection motor 213. Here, biased towards the dust collection motor 213 can be understood as the center of gravity of the cleaning device 110 being relatively closer to the area where the dust collection motor 213 is located on the plane, rather than being on the side away from the dust collection motor 213. In other words, by arranging the heavier main motor 116 at the end of the dust cup 111 away from the dust cup cover 1112, and making its weight greater than the weight of the battery 112 located above the dust cup 111, the cleaning device 110 can form a center of gravity distribution concentrated towards the dust collection motor 213 after docking. In this way, not only can the center of gravity be adjusted using the existing main components inside the cleaning device 110, but the need for additional counterweight structures can also be reduced.

[0179] In some embodiments, the weight relationship between the main motor 116 and the battery 112 can be achieved through component selection, housing material, mounting bracket structure, or configuration of partial accessories. For example, the main motor 116 can adopt a relatively large motor assembly, fan assembly, or integrated structure with a mounting base, while the battery 112 can adopt a single battery pack, a split battery module, or a lightweight battery pack, so that the weight of the main motor 116 is greater than the weight of the battery 112. Furthermore, the battery 112 may be completely above the dust cup 111 or at least partially above it; the end of the main motor 116 located on the dust cup 111 away from the dust cup cover 1112 may be directly adjacent to it or spaced apart by a transition air duct, connecting housing, or mounting cavity, as long as the overall relative positional relationship is satisfied, this application does not impose specific limitations in this regard.

[0180] With the above configuration, the main motor 116 is located at the end of the dust cup 111 away from the dust cup cover 1112, and the weight of the main motor 116 is greater than the weight of the battery 112 located above the dust cup 111. This helps to offset the center of gravity of the cleaning device 110 towards the dust collection motor 213 when docked, thereby improving the stability of the cleaning device 110 when docked and parked with the cleaning device auxiliary device 200. Secondly, this center of gravity distribution relationship also helps to reduce the attitude change caused by the off-center load during automatic dust collection, thereby improving the reliability of automatic dust collection.

[0181] According to a third aspect of this application, a cleaning system 100 is provided. For details regarding the specific structure, connection method, and feasible form of the cleaning device 110, the cleaning device auxiliary device 200, the device body 210, the receiving cavity 211, and the cleaning device docking cavity 212, please refer to the foregoing embodiments, and they will not be repeated here.

[0182] In this embodiment, when the cleaning system 100 is in the docked state, the cleaning device 110 is located within the cleaning device docking cavity 212. This can be understood as the entire cleaning device 110 entering the cleaning device docking cavity 212, or at least the main load-bearing portion or functional docking portion of the cleaning device 110 entering the cleaning device docking cavity 212, as long as a stable parking and / or functional cooperation relationship can be formed with the cleaning device auxiliary device 200. Further, in the docked state, the center of gravity of the cleaning system 100 is located within the receiving cavity 211. Here, the center of gravity of the cleaning system 100 refers to the overall center of gravity formed by the cleaning device 110 and the cleaning device auxiliary device 200 in the docked state. Being located within the receiving cavity 211 can be understood as the overall center of gravity falling within the spatial range corresponding to the receiving cavity 211, or its orthographic projection on a plane perpendicular to the height direction falling within the orthographic projection range of the receiving cavity 211. It can also be understood as the overall center of gravity corresponding to the main area where the receiving cavity 211 is located.

[0183] In some embodiments, the receiving cavity 211 may be located in the lower middle or lower region of the device body 210, so that the overall center of gravity of the cleaning system 100 is relatively low after docking. Alternatively, the center of gravity of the cleaning system 100 can be located within the receiving cavity 211 by adjusting the relative positional relationship between the cleaning device docking cavity 212 and the receiving cavity 211, as well as the insertion depth, support position, and tilting posture of the cleaning device 110 within the cleaning device docking cavity 212. The receiving cavity 211 can be a single receiving space or a combined receiving space composed of multiple independent or interconnected sub-cavities, as long as it can define the area where the center of gravity of the cleaning system 100 is located.

[0184] In some possible implementations, the center of gravity of the cleaning system 100 may be located in the middle region, lower region, or near the center of the receiving cavity 211; alternatively, the center of gravity of the cleaning system 100 may fall within the range of the receiving cavity 211 in the height direction, and its orthographic projection on the horizontal plane may also fall within the orthographic projection range of the receiving cavity 211. The overall center of gravity position can also be adapted and adjusted by considering the arrangement of the dust cup 111, battery 112, main motor 116 of the cleaning device 110, and the dust collection and storage components inside the cleaning device auxiliary device 200; this application does not impose specific limitations on this.

[0185] With the above configuration, the center of gravity of the cleaning equipment 110 and the auxiliary device 200 in the docked state is located within the receiving cavity 211. This helps to concentrate the overall mass distribution of the cleaning system 100 in the main bearing area of ​​the device body 210, thereby improving the stability of the cleaning system 100 in the docked and parked state. Secondly, the receiving cavity 211 itself undertakes the functions of dust storage and / or cleaning parts 114 storage. Controlling the center of gravity of the cleaning system 100 within this area also helps to balance the overall weight distribution while achieving functional integration, thereby improving the reliability of the cleaning system 100 during use.

[0186] Based on this, in order to further clarify the internal functional division of the receiving cavity 211 and the center of gravity positioning area of ​​the cleaning system 100 in the docking state, according to an example embodiment of this application, the receiving cavity 211 includes a storage cavity 2111 and a dust collection cavity 2112. The specific functional settings of the storage cavity 2111 and the dust collection cavity 2112 can be referred to the foregoing embodiments, and will not be repeated here.

[0187] Based on this, this application further specifies that along the height direction of the device body 210, the receiving cavity 2111 is located above the dust collection cavity 2112, and in the docked state, the center of gravity of the cleaning system 100 is located within the dust collection cavity 2112. In other words, compared to the solution that only specifies the overall center of gravity as being located within the receiving cavity 211, this embodiment further concentrates the overall center of gravity within the dust collection cavity 2112 in the receiving cavity 211. Here, being located within the dust collection cavity 2112 can be understood as the overall center of gravity of the cleaning system 100 falling within the area corresponding to the dust collection cavity 2112 in spatial position, or falling within the orthographic projection range of the dust collection cavity 2112 in planar orthographic projection relationship. Since the dust collection cavity 2112 is located at a relatively low position, this limitation actually further clarifies that the overall center of gravity of the cleaning system 100 in the docked state is closer to the lower region of the device body 210.

[0188] Therefore, the receiving cavity 211 is divided into an upper storage cavity 2111 and a lower dust collection cavity 2112, which is conducive to the partitioned arrangement of the cleaning component 114 storage function and the dust storage function within the device body 210. Secondly, in the docking state, the center of gravity of the cleaning system 100 is limited to the dust collection cavity 2112, which makes the overall mass distribution more concentrated at the lower position of the device body 210, thereby improving the stability of the cleaning system 100 when docked and parked, and enhancing the reliability of the cooperation during the automatic dust collection process.

[0189] According to one example embodiment of this application, the cleaning system 100 has a non-dating state. In the non-dating state, the cleaning device 110 is separated from the cleaning device auxiliary device 200, that is, the cleaning device 110 is detached from the cleaning device docking cavity 212, and the two no longer form a repositioning engagement relationship. At this time, the cleaning device auxiliary device 200 is in a placement state or a standby state.

[0190] In this embodiment, the center of gravity of the cleaning equipment auxiliary device 200 is further defined as follows: in the non-docked state, the center of gravity of the cleaning equipment auxiliary device 200 is located within the dust collection chamber 2112. Here, the center of gravity of the cleaning equipment auxiliary device 200 refers to the overall center of gravity formed solely by the cleaning equipment auxiliary device 200 itself after the cleaning equipment 110 is separated from the cleaning equipment auxiliary device 200; being located within the dust collection chamber 2112 can be understood as the center of gravity falling within the corresponding area of ​​the dust collection chamber 2112 in space, or its orthographic projection on the plane falling within the orthographic projection area of ​​the dust collection chamber 2112. In other words, even without the cleaning equipment 110 participating in the counterweight, the main mass distribution of the cleaning equipment auxiliary device 200 itself is still controlled in the lower position of the dust collection chamber 2112 area. This allows the cleaning equipment auxiliary device 200 to maintain a relatively stable self-supporting state when placed independently.

[0191] In some embodiments, to ensure that the center of gravity of the cleaning equipment auxiliary device 200 is located within the dust collection chamber 2112, the dust collection bin, dust collection bag, dust collection motor 213, support frame, counterweight, or other heavier components can be arranged close to the dust collection chamber 2112; the storage chamber 2111 can be mainly used to accommodate the relatively lightweight cleaning components 114. Furthermore, by adding bottom mounting components, lower frames, or local reinforcements, the greater mass can be concentrated in the area where the dust collection chamber 2112 is located. This application does not impose specific limitations in this regard.

[0192] Therefore, based on the fact that the storage cavity 2111 is located above the dust collection cavity 2112, this application further confines the center of gravity of the cleaning equipment auxiliary device 200 in the non-connected state to the dust collection cavity 2112. This is beneficial for the cleaning equipment auxiliary device 200 to maintain a low and concentrated mass distribution after the cleaning equipment 110 is separated, thereby improving the stability of the cleaning equipment auxiliary device 200 when placed independently. Secondly, this center of gravity arrangement is also beneficial for reducing the posture disturbance caused by external force collisions or when picking up and putting down the cleaning parts 114, thereby improving the reliability of the cleaning equipment auxiliary device 200 in daily use.

[0193] To further control the magnitude of the center of gravity change of the cleaning system 100 between different usage states, according to an example embodiment of this application, refer to... Figure 5 As shown, compared with the center of gravity o0 of the cleaning system 100 in the non-docked state, the change in position Δ1 of the center of gravity o of the cleaning system 100 in the docked state is less than a first preset value, and the change in position Δ2 of the orthographic projection on the plane perpendicular to the height direction is less than a second preset value. For the specific meanings of the docked state, non-docked state, center of gravity of the cleaning system 100, and height direction, please refer to the aforementioned embodiments, which will not be repeated here.

[0194] The change in position along the height direction can be understood as the vertical displacement of the overall center of gravity when the cleaning system 100 switches from a non-docked state to a docked state, or vice versa. The change in position of the orthographic projection on a plane perpendicular to the height direction can be understood as the horizontal offset of the overall center of gravity in the aforementioned two states. In other words, this embodiment does not limit the center of gravity to a specific area in a certain state, but further limits the change in the center of gravity between the two states to a small range. In this way, the overall mass distribution of the cleaning system 100 can remain relatively continuous and stable during the repositioning or removal of the cleaning device 110.

[0195] Furthermore, the first preset value is less than or equal to 30mm; and / or, the second preset value is less than or equal to 160mm. In other words, when the cleaning system 100 switches between docking and non-docking states, the change in the overall center of gravity in the height direction is limited to within 30mm, for example, it can be 10mm, 15mm, 20mm, 25mm, or 30mm; and / or, its offset in the horizontal plane is limited to within 160mm, for example, it can be 80mm, 100mm, 120mm, 140mm, or 160mm. Here, "and / or" can be understood as both parameters can be limited simultaneously, or only one parameter can be limited. In addition, the first and second preset values ​​can also be adapted and adjusted according to products with different size specifications, different overall weights, and different base contours, and this application does not impose specific restrictions on this. By constraining the specific numerical range, the center of gravity control requirements of the cleaning system 100 can be made clearer, which facilitates structural design, installation layout, and overall machine verification.

[0196] It should be understood that this application is not limited to the detailed structure and arrangement of the components proposed in this application. This application can have other embodiments and can be implemented and executed in various ways. The foregoing variations and modifications fall within the scope of this application.
