[0071] See also Figures 1 to 7 The present invention provides a cleaning device, which can specifically be a vacuum cleaner. The vacuum cleaner can drive gas flow to remove dirt in the area to be cleaned, thereby achieving the purpose of cleaning the area to be cleaned.

[0072] More specifically, the cleaning device provided by the present invention is a handheld vacuum cleaner, that is, a vacuum cleaner product that can be handheld by the user. It can be understood that a handheld vacuum cleaner has multiple states during use, such as a placement state when it is stationary on a carrying surface, a handheld state when it is used for transfer or vacuuming, etc. A handheld vacuum cleaner may have different orientations and postures when it is in different states. Therefore, for ease of understanding, in the following embodiments, the orientation and posture of the cleaning device when it is in a placement state are used as an example for explanation. In this state, the cleaning device has an up and down direction that is roughly perpendicular to the carrying surface, and a lateral direction that is located on the carrying surface or roughly parallel to the carrying surface, and the lateral direction is roughly perpendicular to the up and down direction. The cleaning device and its various components also have an upstream and downstream direction corresponding to the airflow direction when it is started.

[0073] In view of the above, please combine Figures 1 to 4 , the following will first explain the basic components of cleaning equipment:

[0074] The cleaning device at least includes an air inlet portion 100 , a dust collecting portion 200 , a gripping portion 300 , a driving device 400 and a power supply device 500 .

[0075] The air inlet 100 is the component of the cleaning device that receives external air. In one embodiment, the air inlet 100 is generally cylindrical and defines an air inlet duct that roughly matches its shape. The upstream opening of the air inlet duct defines the air inlet 110 of the cleaning device, while the downstream opening of the air inlet duct communicates with the upstream opening of the dust collection unit 200.

[0076] The air inlet portion 100 has an air inlet axis S1. When the air inlet portion 100 is substantially cylindrical as described above, the air inlet axis S1 corresponds to the central axis of the cylinder. The specific extension direction of the air inlet axis S1 is not limited. For example Figures 1 to 7 In the embodiment shown, the air inlet axis S1 may extend along the aforementioned transverse direction. Alternatively, in other embodiments, the air inlet axis S1 may extend along the aforementioned up-down direction, or along other directions intersecting the up-down direction or the transverse direction.

[0077] When the air received by the air inlet 100 enters the dust collecting section 200, the dust collecting section 200 can intercept dust, hair, and other impurities carried in the air, thereby collecting dust. When the dust collecting section 200 primarily extends in the vertical direction, the air inlet 100 can be provided protruding from one lateral side of the dust collecting section 200. The air inlet 100 and the dust collecting section 200 can be integrally formed, or they can be separately formed and then connected in a detachable or non-detachable manner.

[0078] At least a space for storing trapped dirt is formed inside the dust collecting portion 200. Therefore, in one embodiment, the dust collecting portion 200 includes a cup body 210. The cup body 210 is generally cylindrical, and the central axis of the cup body 210 can extend in the vertical direction. The radial direction of the cup body 210 generally corresponds to the horizontal direction.

[0079] The downstream opening of the cup body 210 can be used for relatively clean gas to be discharged outward. In one embodiment, the downstream opening of the cup body 210 can be reused to discharge the dirt stored in the cup body 210 outward, for example, by dumping the cup body 210, negative pressure suction, etc. Or in another embodiment, in addition to its own upstream opening and downstream opening, the cup body 210 is also provided with another opening, which can be opened at any suitable position, such as at the lower end of the cup body 210. Based on this, the dust collecting part 200 also includes a cover body 220, which is movably connected to the cup body 210 and can open or close the opening during its movement. There is no restriction on the movement of the cover body 220 relative to the cup body 210, and it can be a translation movement or a flip movement in the direction of approaching and moving away from the opening.

[0080] In view of the above, in order to better achieve the dust collection purpose of the dust collecting section 200, the cleaning device may further include a separation device, which is disposed within the dust collecting section 200 and is capable of intercepting dirt in the gas in a suitable separation manner. The above separation method may be, but is not limited to, physical filtration, centrifugal separation, or gravity sedimentation. Taking physical filtration as an example, the separation device may include at least one filter. The filter may be, for example, a filter mesh, a filter sponge, filter paper, a multi-cone filter, or the like.

[0081] When at least two filters are arranged in the dust collecting section 200 at intervals along the airflow direction, at least two-stage filtration of the gas can be achieved. In this case, each filter can be capable of producing the same filtering effect or different filtering effects. Different filtering effects can include, but are not limited to, the ability to filter waste of different outer diameters, different shapes, different amounts of waste, and waste from different areas.

[0082] Specific as Figures 3 and 4As shown, in one embodiment, the dust collecting section 200 includes the aforementioned cylindrical cup body 210 and discrete components, the discrete components including a first filter 821 and a second filter 822. The first filter 821 is a cylindrical filter coaxially disposed with the cup body 210, and the second filter 822 is a multi-cone filter coaxially disposed with the cup body 210. The first filter 821 surrounds the periphery of the second filter 822. The downstream outlet of the air inlet section 100 and the upstream opening of the dust collecting section 200 face at least a portion of the mesh surface of the first filter 821, while the downstream opening of the dust collecting section 200 faces the axial end of the second filter 822.

[0083] In view of the above, the driving device 400 can drive the gas from the air inlet 100 into the dust collecting part 200. The driving device 400 includes but is not limited to a fan, and any suitable air-purging device that can meet the air-purging requirements of the cleaning equipment can be used. The fan can be but is not limited to a centrifugal fan, an axial flow fan, a cross-flow fan, etc. The fan has an air suction side and an air exhaust side. Among them, the air suction side is connected to the downstream opening of the dust collecting part 200, and the air exhaust side can be connected to the air outlet 610 of the cleaning equipment.

[0084] To achieve high-reliability operation of the drive unit 400, in a further embodiment, the cleaning apparatus further includes a pre-filter 810. The pre-filter 810 is disposed between the downstream opening of the dust collecting section 200 and the upstream side of the drive unit 400 (e.g., the suction side of the blower). Similarly to the above, the pre-filter 810 can be any suitable filter that effectively filters the gas upstream of the drive unit 400, preventing contaminants from entering, for example, the blower interior and causing performance failures.

[0085] like Figure 4 As shown, in one embodiment, the pre-filter 810 is roughly cylindrical, and one axial end is connected to the downstream opening of the dust collecting part 200, and its radial side is connected to the upstream of the driving device 400 (for example, the suction side of the fan).

[0086] Furthermore, in one embodiment, the cleaning device also includes an air guide portion 900, which is formed with an air guide duct, and the air guide duct is connected between the downstream of the pre-filter 810 and the upstream of the driving device 400, so as to be able to adapt to the relative positions of the pre-filter 810 and the driving device 400, and better guide the gas discharged from the downstream of the pre-filter 810 to the upstream of the driving device 400.

[0087] The air guide portion 900 can be configured to be connected to the dust collecting portion 200, and when connected in place, the pre-filter 810 can be fixed and limited between the two. At this time, in order to make the appearance beautiful, the air guide portion 900 can be configured to basically adapt to the shape and size of the dust collecting portion 200. For example, when the dust collecting portion 200 includes a cylindrical cup body 210 as described above, the air guide portion 900 can be connected to one axial end of the cup body 210, and can also be roughly configured to be cylindrical. The connection between the air guide portion 900 and the dust collecting portion 200 can be achieved by an integral molding method, or it can be achieved by a detachable or non-detachable connection operation after the two are separately molded. Among them, the detachable connection can better facilitate the disassembly and assembly of the pre-filter 810, and the detachable connection fixation can be, but is not limited to, one or more of the following methods: screw fixation, snap fixation, magnetic fixation, plug fixation, etc.

[0088] In the above description, the shape of the air guide duct is adapted to the specific positioning of the pre-filter 810 and the drive device 400. For example, if the pre-filter 810 is a cylindrical filter as described above, and the drive device 400 is disposed radially to one side of the pre-filter 810, the air guide duct of the air guide portion 900 may partially surround the periphery of the pre-filter 810 in an arc shape, or may completely surround the periphery of the pre-filter 810 in a ring shape.

[0089] In view of the above, the power supply device 500 is at least electrically connected to the driving device 400 to provide the required power to the driving device 400. Depending on actual needs, the power supply device 500 may be a wired power supply device, such as a cable or adapter connected to the mains power. Of course, the power supply device 500 may also be a wireless power supply device, such as a disposable battery device or a rechargeable battery device.

[0090] The driving device 400 and the power supply device 500 can be directly externally mounted on the dust collecting portion 200 / air guide portion 900, or in one embodiment, the cleaning device further includes a mounting portion 600 connected to the dust collecting portion 200 / air guide portion 900. The mounting portion 600 defines an interior mounting cavity, and the driving device 400 and / or the power supply device 500 are housed within the mounting portion 600.

[0091] When the dust collecting part 200 is cylindrical as described above, in order to make the appearance uniform, the mounting part 600 can also be set to be cylindrical, which helps to avoid the formation of sharp structures on the outer wall of the entire machine, thereby helping to reduce interference between the cleaning equipment and the surrounding environment.

[0092] Specifically, when the driving device 400 is accommodated in the installation cavity, the outer wall of the installation portion 600 can be provided with an air outlet 610 connected to the installation cavity. The air outlet 610 can be specifically arranged corresponding to the downstream of the driving device 400 (for example, the exhaust side of the fan), thereby realizing gas circulation between the inside of the cleaning equipment and the external environment.

[0093] The air outlet 610 may be provided as one or more air outlets. The shape of a single air outlet 610 or the arrangement of the multiple air outlets 610 may be different to suit the type of the drive device 400. For example, when the drive device 400 includes a fan as described above, and the exhaust side of the fan is annular along its axis, the air outlets 610 may be arranged continuously or intermittently along the circumference of the mounting portion 600.

[0094] In view of the above, the grip portion 300 mainly refers to the portion of the entire device for the user to hold. The grip portion 300 is generally spaced apart on one lateral side of the dust collecting portion 200, and can be specifically arranged on the opposite side of the air inlet portion 100. The shape, size, material, etc. of the grip portion 300 are not limited, for example, it can be a longitudinal, arc-shaped or annular rod, etc. Figures 1 to 2 In the illustrated structure, the grip portion 300 is substantially in the shape of a longitudinal rod and has a grip axis S2 . The grip axis S2 may extend in the vertical direction or extend in a direction that forms a certain inclination angle relative to the vertical direction.

[0095] Since the main purpose of the present invention is to make the center of gravity of the cleaning device as reasonably distributed as possible in, for example, the placement state and / or the handheld state, therefore, in combination with one or more of the above embodiments, the present invention mainly provides the following designs:

[0096] First see Figures 1 to 4 In the first design provided by the present invention, the driving device 400 and the power supply device 500 are both arranged at the same end of the gripping portion 300, and the driving device 400 and the power supply device 500 are both arranged above the air inlet axis S1.

[0097] In this way, the weight of the driving device 400 and the power supply device 500 is relatively large. By concentrating the driving device 400 and the power supply device 500 at the same end of the gripping portion 300 and above the air inlet axis S1, on the one hand, the center of gravity of the driving device 400 and the power supply device 500 is sufficiently close to the gripping portion 300, so that it is more labor-saving when the user operates the entire machine through the gripping portion 300; on the other hand, the weight of the driving device 400, the power supply device 500 and the gripping portion 300 are more concentrated, which helps to place the entire machine stably on the load-bearing surface; in addition, it also helps to arrange the driving device 400, the power supply device 500, the gripping portion 300 and the air inlet portion 100 reasonably around the dust collecting portion 200 in terms of appearance, which helps to make the structure of the entire machine compact and the appearance beautiful.

[0098] Based on this design, since the grip portion 300 and the air inlet portion 100 are not restricted in their upward and downward directions, in actual application, the driving device 400 and the power supply device 500 can be jointly arranged at the upper end of the grip portion 300 or at the lower end of the grip portion 300. Figures 1 to 2 In the illustrated structure, the horizontal projection of the air inlet portion 100 is sufficiently close to the grip portion 300 or falls within the area where the grip portion 300 is located. Therefore, in order to achieve the purpose of arranging the drive device 400 and the power supply device 500 above the air inlet axis S1, the drive device 400 and the power supply device 500 can be specifically arranged at the upper end of the grip portion 300. The relatively large mass of the drive device 400 and the power supply device 500 has a more concentrated center of gravity above the grip portion 300, which helps to save effort when holding the device. Moreover, the relatively large size of the drive device 400 and the power supply device 500 is closer to each other, making the drive device 400 closer to the downstream of the dust collection portion 200 (or downstream of the air guide portion 900), which helps to make the structure of the entire device more compact.

[0099] The driving device 400 and the power supply device 500 can be arranged in the vertical direction, or along the circumference of the dust collecting part 200, or along the air inlet axis S1 (i.e., horizontally). And wherein, the driving device 400 and the power supply device 500 can be arranged along the air inlet axis S1 so that the driving device 400 is closer to the dust collecting part 200 relative to the power supply device 500, or the power supply device 500 is closer to the dust collecting part 200 relative to the driving device 400. Figure 4 In the structure shown, the driving device 400 is arranged on the air inlet axis S1, and is closer to the dust collecting section 200 relative to the power supply device 500, so that it is more conducive to the upstream of the driving device 400 (for example, the suction side of the fan) being adjacent to or directly connected to the downstream of the dust collecting section 200, so as to better achieve the purpose of connecting the external air to the air inlet 100, flowing through the dust collecting section 200, and finally being discharged from the downstream of the dust collecting section 200.

[0100] In combination with the above-mentioned embodiment of the mounting portion 600, further, the mounting portion 600 and the air inlet portion 100 can be respectively protruded and arranged on both sides of the dust collecting portion 200, and the mounting portion 600 is located above the air inlet portion 100, the driving device 400 and the power supply device 500 are both accommodated in the mounting portion 600, and the gripping portion 300 is connected to the bottom of the mounting portion 600. The shape of the mounting portion 600 can also be adapted to the arrangement direction of the driving device 400 and the power supply device 500 and be arranged to extend in a cylindrical shape along the air inlet axis S1. In this way, on the one hand, the mounting cavity provided by the mounting portion 600 is more adapted to the shape of the driving device 400 and the power supply device 500, which helps to securely install the driving device 400 and the power supply device 500 in the mounting cavity; on the other hand, it also makes the appearance of the entire machine more beautiful and the material used more economical.

[0101] When the holding portion 300 is elongated and has a holding axis S2 as described above, specifically, the holding axis S2 can be inclined and extended from top to bottom in a direction gradually away from the dust collecting portion 200. On the one hand, it helps to form a variable distance between the holding portion 300 and the dust collecting portion 200 to adapt to the different handheld size requirements of different users; on the other hand, it helps to form a roughly triangular shape between the holding portion 300, the dust collecting portion 200 and the bearing surface when in the placed state, which helps to place it stably and is particularly suitable for stably bearing the gravity applied by the drive device 400 and the power supply device 500 connected to its upper end.

[0102] In a further embodiment, the cleaning device may further include a support portion 710. The support portion 710 and the mounting portion 600 are protruding from the same side of the dust collecting portion 200 and are spaced apart from each other from bottom to top. The grip portion 300 is connected between the support portion 710 and the mounting portion 600 to increase the connection strength of the grip portion 300 relative to the dust collecting portion 200. When the support portion 710 is provided at the lower end of the grip portion 300, compared to a solution in which only the grip portion 300 is provided, the support portion 710 can provide a larger bottom surface for contact with the receiving surface, thereby facilitating the uniform distribution of the gravity exerted by the driving device 400 and the power supply device 500, effectively preventing stress concentration, and making the entire device more stable when placed on the receiving surface.

[0103] Furthermore, in one embodiment, the cleaning device may further include a reinforcement portion 720, which is located between the mounting portion 600, the support portion 710, the dust collecting portion 200, and the grip portion 300. The upper and lower ends of the reinforcement portion 720 are respectively connected to the mounting portion 600 and the support portion 710, and one side of the reinforcement portion 720 is connected to the dust collecting portion 200. The reinforcement portion 720 can be extended and arranged to adapt to the shape of the sidewall of the dust collecting portion 200 at its location, thereby expanding the connection area between the reinforcement portion 720 and the dust collecting portion 200. The provision of the reinforcement portion 720 helps to strengthen the connection strength between the mounting portion 600 and the grip portion 300, between the grip portion 300 and the support portion 710, between the support portion 710 and the dust collecting portion 200, and between the mounting portion 600 and the dust collecting portion 200.

[0104] It should be noted that at least two of the above-mentioned mounting portion 600, dust collecting portion 200 (and / or air guide portion 900), gripping portion 300, supporting portion 710 and reinforcing portion 720 may be integrally formed, or may be obtained by detachable or non-detachable connection after separate molding.

[0105] Also, see Figures 1 to 4 、 Figures 6 and 7 In the second design provided by the present invention, the driving device 400 and the power supply device 500 are both arranged at the same end of the gripping portion 300, and the pre-filter 810, the driving device 400 and the power supply device 500 are arranged in sequence along the air inlet axis S1.

[0106] In this way, the weight of the driving device 400 and the power supply device 500 is relatively large. By concentrating the driving device 400 and the power supply device 500 at the same end of the grip 300, on the one hand, the center of gravity of the driving device 400 and the power supply device 500 is sufficiently close to the grip 300, so that it is more labor-saving when the user operates the entire machine through the grip 300; on the other hand, the weight of the driving device 400, the power supply device 500 and the grip 300 are more concentrated on the side where the entire machine is located, which helps to place the entire machine stably on the load surface; and by arranging the pre-filter 810, the driving device 400 and the power supply device 500 in sequence along the air inlet axis S1, the pre-filter 810, the driving device 400 and the power supply device 500 are closer, which helps the pre-filter 810 to better filter the driving device 400, and also helps to have a simpler electrical connection structure between the driving device 400 and the power supply device 500, and also helps to make the structure of the entire machine compact and the appearance beautiful.

[0107] Based on this design, combined with the above-mentioned embodiment of the mounting portion 600, specifically, the mounting portion 600 and the air inlet portion 100 are respectively protruded on both sides of the dust collecting portion 200, and the driving device 400 and the power supply device 500 are both accommodated in the mounting portion 600; and when the driving device 400 and the power supply device 500 are both arranged at the upper end of the holding portion 300 as described above, the pre-filter 810 can be specifically arranged at the upper end of the dust collecting portion 200, and the holding portion 300 is connected to the bottom of the mounting portion 600.

[0108] Continuing with the above-mentioned embodiment in which the second filter 822 is a multi-cone filter and the pre-filter 810 is a cylindrical filter, specifically, the second filter 822 and the pre-filter 810 can be coaxially arranged. The outer diameter of the second filter 822 can be set to be larger than the periphery of the pre-filter 810 to increase the gas flow and enhance the filtering effect of the second filter 822. At this time, when the cleaning equipment also includes the air guide part 900 as described above, the air guide part 900 surrounds the periphery of the pre-filter 810, and the outer diameter and shape of the air guide part 900 are respectively adapted to the outer diameter and shape of the dust collecting part 200, so that the overall appearance of the dust collecting part 200, the air guide part 900 and the pre-filter 810 is unified and the center of gravity is on the same axis.

[0109] Also, see Figures 1 to 4 In the third design provided by the present invention, the driving device 400 and the power supply device 500 are both arranged at the same end of the gripping portion 300, and are arranged in sequence on both sides of the gripping axis S2 along the air inlet axis S1, and the gripping axis S2 does not pass through the driving device 400.

[0110] In this way, the weight of the driving device 400 and the power supply device 500 is relatively large. By concentrating the driving device 400 and the power supply device 500 at the same end of the grip 300, on the one hand, the center of gravity of the driving device 400 and the power supply device 500 is sufficiently close to the grip 300, so that it is more labor-saving when the user operates the entire machine through the grip 300; on the other hand, the weight of the driving device 400, the power supply device 500 and the grip 300 are more concentrated on the side, which helps to place the entire machine stably on the load surface; and by arranging the driving device 400 and the power supply device 500 on both sides of the grip axis S2, and the grip axis S2 does not pass through the driving device 400, the gravity exerted by the driving device 400 and the power supply device 500 on the grip 300 is more balanced on the air inlet axis S1, and it also helps to reduce the interference of the driving device 400 on the grip 300 in the running state to a certain extent, thereby ultimately helping to improve the user experience.

[0111] Based on this design, the holding axis S2 can be optionally set not to pass through the power supply device 500; or it can be optionally set to pass through at least part of the power supply device 500, which can be specifically set according to the actual specifications of the power supply device 500.

[0112] When the gripping axis S2 is configured as described above to extend obliquely from top to bottom in a direction gradually departing from the dust collecting portion 200, in order to prevent the gripping axis S2 from passing through the drive device 400 or the power supply device 500, the distance between the drive device 400 and the power supply device 500 may be appropriately widened during installation. When it is necessary to minimize the distance between the drive device 400 and the power supply device 500, the side surface of the drive device 400 close to the gripping portion 300 along the air inlet axis S1 and / or the side surface of the power supply device 500 close to the gripping portion 300 along the air inlet axis S1 may be configured to be inclined in the direction in which the gripping portion 300 extends. The above-mentioned tilting may be achieved by specially designing the structures of the drive device 400 and the power supply device 500, changing the shapes of the corresponding side surfaces of the drive device 400 and / or the power supply device 500, or by appropriately tilting the drive device 400 and / or the power supply device 500 during installation.

[0113] Also, see Figures 5 and 6 In the fourth design provided by the present utility model, the driving device 400 and the power supply device 500 are both arranged at the same end of the gripping portion 300, the bottom surface of the dust collecting portion 200 is the first bottom surface 221, and the cleaning device also has a second bottom surface 711 located on the bottom side of the gripping portion 300. The first bottom surface 221 and the second bottom surface 711 are not arranged coplanar, and the height difference H between the two is not less than 5 mm.

[0114] In this way, the weight of the driving device 400 and the power supply device 500 is relatively large. By concentrating the driving device 400 and the power supply device 500 at the same end of the gripping portion 300, on the one hand, the center of gravity of the driving device 400 and the power supply device 500 is made sufficiently close to the gripping portion 300, thereby saving effort when the user operates the entire machine through the gripping portion 300; on the other hand, the weight of the driving device 400, the power supply device 500 and the gripping portion 300 are more concentrated on the side where the entire machine is located, which helps to place the entire machine stably on the supporting surface; and by forming a height difference between the first bottom surface 221 and the second bottom surface 711, in the placed state, only the first bottom surface 221 or the second bottom surface 711 is supported on the supporting surface, which helps to reduce the constraints on the size of the supporting surface, so that even if the area provided by the supporting surface is limited, the entire cleaning device can be placed stably.

[0115] Regarding the first bottom surface 221: When the dust collecting part 200 includes the cup body 210 and the separation device provided in the cup body 210 as described above, if the bottom end of the cup body 210 is closed, the bottom surface of the cup body 210 can directly constitute the first bottom surface 221; if the bottom end of the cup body 210 is open, and the dust collecting part 200 also includes the cover body 220 as described above, the bottom surface of the cover body 220 constitutes the first bottom surface 221.

[0116] It should be noted that, when the bottom surface of the dust collecting portion 200 is a flat plane, the first bottom surface 221 may refer to the entire bottom surface of the dust collecting portion 200. However, when the bottom surface of the dust collecting portion 200 is at least partially concave-convex, the first bottom surface 221 mainly refers to the convex surface at the most downwardly convex structure among the concave-convex surfaces.

[0117] Regarding the second bottom surface 711 : When the cleaning device only includes the grip 300 , the bottom surface of the grip 300 directly constitutes the second bottom surface 711 . If the cleaning device also includes the aforementioned support 710 in addition to the grip 300 , the bottom surface of the support 710 constitutes the second bottom surface 711 .

[0118] Similarly, when the bottom surface of the grip portion 300 / support portion 710 is a flat plane, the second bottom surface 711 may refer to the entire bottom surface of the grip portion 300 / support portion 710. However, when the bottom surface of the grip portion 300 / support portion 710 is at least partially concave-convex, the second bottom surface 711 primarily refers to the convex surface of the most downwardly convex structure in the concave-convex surface.

[0119] Due to the height difference between the first bottom surface 221 and the second bottom surface 711, when in the placement state, generally the first bottom surface 221 or the second bottom surface 711 is selected to be supported on the bearing surface:

[0120] In the first selection scheme, the lower one of the first bottom surface 221 and the second bottom surface 711 can be optionally in contact with the bearing surface, and the higher one of the first bottom surface 221 and the second bottom surface 711 can be suspended above the bearing surface, so as to achieve the purpose of reducing the occupation of the board surface of the bearing surface by the entire cleaning equipment as described above.

[0121] Based on this, in order to make the lower first bottom surface 221 or the second bottom surface 711 more stably placed on the supporting surface, in one embodiment, the downward projection of the center of gravity of the cleaning equipment can be optionally placed on or close to the lower one of the first bottom surface 221 and the second bottom surface 711.

[0122] Specifically Figure 6As an example, the second bottom surface 711 shown is arranged lower than the first bottom surface 221. The downward projection of the center of gravity of the cleaning device can be placed on or close to the second bottom surface 711. In this way, the gravity of the entire cleaning device is concentrated on the second bottom surface 711 in contact with the support surface, preventing excessive force on the first bottom surface 221 from causing the entire device to become unbalanced and tip over.

[0123] Of course, there are many ways to achieve the downward projection of the center of gravity of the cleaning device falling on or close to the second bottom surface 711. For example, the components with greater gravity in the cleaning device, such as the above-mentioned driving device 400 and power supply device 500, can be more concentrated on the side where the gripping part 300 is located. Or more other components in the cleaning device can be concentrated on the side where the gripping part 300 is located. It can also be achieved by adding a counterweight on the side where the gripping part 300 is located, or conversely, adding a structure that can apply an upward external force on the side where the dust collecting part 200 is located. Among them, the structure that can apply an upward external force is, for example, a structure that can be hung with a hook when a hook is provided on the peripheral side of the bearing surface; or a structure such as an airbag filled with a safety gas with a density less than that of air.

[0124] In the second selection scheme, if the supporting surface is defined by a structure such as a tabletop or platform with side edges, the higher one of the first bottom surface 221 and the second bottom surface 711 can be selected to contact the supporting surface, and the lower one of the first bottom surface 221 and the second bottom surface 711 can be suspended beside the side edge of the supporting surface. This not only reduces the occupation of the supporting surface by the cleaning equipment as a whole, but also because the first bottom surface 221 and the second bottom surface 711 have a height difference H, a step is formed between the two, and the step can abut against the side edge of the supporting surface, which helps to limit the displacement of the cleaning equipment relative to the supporting surface when in the installed state.

[0125] Based on this, in order to make the placement of the higher first bottom surface 221 or the second bottom surface 711 on the supporting surface more stable, in one embodiment, the downward projection of the center of gravity of the cleaning equipment can be optionally placed on or close to the higher one of the first bottom surface 221 and the second bottom surface 711.

[0126] It should be noted that, where feasible, each embodiment in the above-mentioned first design, each embodiment in the second design, each embodiment in the third design, and each embodiment in the fourth design can be combined at least two by two, and after the combination, their corresponding technical effects can also be superimposed.

[0127] It should be emphasized that the cleaning device in any of the above embodiments can be used alone or in conjunction with other mechanisms. Based on this, the utility model also provides a cleaning system, which includes a base station and the above cleaning device. The cleaning device is used in conjunction with the base station, and when docked, interactive operations can be completed between the cleaning device and the base station. The specific form of the interactive operation is not limited, for example, it can be to clean, charge, decontamination, etc. for the cleaning device through the base station.
