Description
TECHNICAL FIELD

The present application belongs to the technical field of a cleaning device, and particularly relates to a cleaning device and a cleaning system.


BACKGROUND

The dust cup is a holding structure with a holding space for holding rubbish. The dust cup is configured to be used in a cleaning device, and a fan is used to generate a negative pressure adsorption force in the holding space of the dust cup, so that the rubbish outside the cleaning device is sucked into the holding space of the dust cup. The dust cup is equipped with a dust extraction structure, which is provided with a dust extraction opening. When the cleaning device is parked at the base station, the dust collection opening of the base station and the dust extraction opening are docked and communicated, and the rubbish in the holding space enters the dust collection opening from the dust extraction opening, so as to be collected by the base station.


In the related art, the dust extraction structure is provided at the bottom of the dust cup. The dust extraction structure must have the following two functions: one is to keep the dust extraction opening closed during the dust suction of the cleaning device, and the other is to keep the dust extraction opening open during the dust extraction of the base station. Therefore, the dust extraction structure is complex, and a sufficient space must be provided for the dust extraction structure and for allowing the dust extraction opening of the dust extraction structure to switch between the opened state and the closed state.


However, the space at the bottom of the dust cup is limited, and the dust extraction structure is provided at the bottom of the dust cup, so under the limited space, it is more complex to configure the dust extraction structure, and the convenience of switching the dust extraction opening between the opened state and the closed state is reduced, which results in a low efficiency of the dust extraction.


SUMMARY

The dust collection assembly 10, the cleaning device 100 and the cleaning system 1000 provided by embodiments of the present application are described.


Referring to FIGS. 1 to 4, the dust collection assembly 10 provided in this embodiment of the present application is provided with a dust inlet 101, a dust extraction opening 102, and a dust collection cavity 103 in communication with the dust inlet 101 and the dust extraction opening 102. The dust collection assembly 10 includes a bottom wall 11 and a sidewall 12, the sidewall 12 is extended along a circumferential direction of the bottom wall 11, the sidewall 12 is connected to the bottom wall 11 to form the dust collection cavity 103, and the dust extraction opening 102 is provided on the sidewall 12.


The bottom wall 11 refers to a structural wall that forms a portion of the dust collection cavity 103 and is located below the sidewall 12. Generally, the bottom wall 11 substantially likes a plate, and a plate structure has a certain thickness and a certain extension area, and a ratio of the extension area to the thickness is large. The bottom wall 11 may be any plate structure, such as a circle, an oval, a polygon, etc., and the general shape of the bottom wall 11 may be a regular shape or an irregular shape.


The circumferential direction of the bottom wall 11 refers to a circumferential direction extending along the edge of the bottom wall 11, and also refers to the circumferential direction a in FIGS. 3 and 4. An axis direction b in FIGS. 3 and 4 is perpendicular to the circumferential direction. When the bottom wall 11 is of a regular plate structure, the bottom wall 11 has a central axis, i.e. the dust collection assembly 10 is allowed to have a central axis, and the axis direction b refers to the extension direction of the central axis.


The sidewall 12 refers to a structural wall that forms a portion of the dust collection cavity 103 and is located above the bottom wall 11. The sidewall 12 is extended along the circumferential direction a as described above, and wraps around along the circumferential direction a to form a ring. A lower peripheral edge of the sidewall 12 is connected to the bottom wall 11 to form the dust collection cavity 103. The sidewall 12 is extended for a certain distance away from the bottom wall 11 to ensure that the sidewall 12 has a certain extension area in the axis direction b as described above, in addition to having a certain extension area along the circumferential direction a.


Compared with the related art, the dust collection assembly 10 provided by the present application has a sidewall 12 extending along a circumferential direction of the bottom wall 11. The sidewall 12 is connected to the bottom wall 11 to form a dust collection cavity 103, the sidewall 12 has sufficient utilizable space compared to the bottom wall 11. The dust extraction opening 102 is provided on the sidewall 12. The design that the dust extraction opening 102 and its ancillary structures are provided on the bottom wall 11 is canceled, and the bottom region near the bottom wall 11 is utilized as the volume of the dust collection cavity 103, which improves the utilization of the dust collection space. The sidewall 12 has sufficient utilizable space, so that the design of the dust extraction opening 102 need not be limited to the structural complexity and the number of the dust extraction openings 102, allowing for a diversity of choices and settings of the structure and the number of the dust extraction openings 102 according to the actual needs. The sufficient utilizable space is conducive to improving the convenience of switching the dust extraction opening 102 between the opened state and the closed state, and improving the efficiency of the cleaning base station 10001 sucking dust from the dust extraction opening 102.


As shown in FIG. 3, in some embodiments, a portion of the sidewall 12 is protruded relative to another portion of the sidewall 12 in a direction pointing from an inside of the sidewall 12 to an outside of the sidewall 12, and the dust extraction opening 102 is provided on a protrusion portion 121 of the sidewall 12. The protrusion portion 121 is protruded towards the outside of the dust collection cavity 103 without occupying the inner space of the dust collection cavity 103, thereby ensuring a normal use volume inside the dust collection cavity 103. Alternatively, the inside of the protrusion portion 121 can be provided with an additional portion of the cavity as an expansion of the internal normal use space of the dust collection cavity 103, thereby improving the utilization of the internal space of the dust collection cavity 103 and increasing the maximum dust collection volume of the dust collection cavity 103. In addition, since the protrusion portion 121 does not occupy the internal space of the dust collection cavity 103, that is, there will be no blind angle, inaccessible to a wind path of the dust extraction, formed between the protrusion portion 121 and the inner wall of the dust collection cavity 103, thereby preventing obstruction in the process that the to-be-collected dust material is extracted out from the dust collection cavity 103, and ensuring that the extraction of the dust is completed.


In this embodiment, the protrusion portion 121 is formed by the sidewall 12 as a whole protruding outward, and the sidewall 12 constituting the dust collection cavity 103 is an integrated structure for simplifying the structure of the dust collection cavity 103, and thus simplifying the structure of the dust collection assembly 10. The dust collection assembly 10 is applied to the cleaning device 100 and the cleaning system 1000 for simplification of the structures of the cleaning device 100 and the cleaning system 1000.


In some embodiments, the sidewall 12 is provided with a plurality of protrusion portions 121, each of which is provided with a dust extraction opening 102. The plurality of dust extraction openings 102 increase an area for dust extraction, which is conducive to reducing the time that the cleaning base station 10001 sucks dust from the dust extraction openings 102, thereby improving the efficiency of dust suction, and also reducing the loss of use of the cleaning base station 10001.


In this embodiment, the plurality of protrusion portions 121 are arranged sequentially at intervals. The plurality of protrusion portions 121 are arranged in a direction consistent with the circumferential direction a as described above. Alternatively, the plurality of protrusion portions 121 are arranged in a direction consistent with the axis direction b as described above, i.e., perpendicular to the circumferential direction a. Alternatively, a portion of the plurality of protrusion portions 121 are arranged in a direction consistent with the circumferential direction a as described above, and another portion of the plurality of protrusion portions 121 are arranged in a direction consistent with the axis direction b as described above. Alternatively, the plurality of protrusion portions 121 may be flexibly selected and arranged along a direction angled with the circumferential direction a or the axis direction b according to actual needs. Alternatively, the plurality of protrusion portions 121 may be randomly arranged. In this embodiment, at least one dust extraction opening 102 is provided on one of the protrusion portions 121. The arrangement of all the dust extraction openings 102 on the sidewall 12 depends on the arrangement of the protrusion portions 121, which will not be repeated herein.


In some embodiments, the protrusion portion 121 is provided with a plurality of dust extraction openings 102. The plurality of dust extraction openings 102 increase the area for dust extraction, which is conducive to reducing the time that the cleaning base station 10001 sucks dust from the dust extraction openings 102, thereby improving the efficiency of dust extraction, and also reducing the loss of use of the cleaning base station 10001.


In this embodiment, if the extension direction of the protrusion portion 121 is consistent with the circumferential direction a as described above, the plurality of dust extraction openings 102 are preferably arranged in a direction consistent with the circumferential direction a as described above. Alternatively, the extension direction of the protrusion portion 121 is consistent with the axis direction b as described above, i.e., perpendicular to the circumferential direction a, then the plurality of dust extraction openings 102 are preferably arranged in a direction consistent with the axis direction b as described above. Alternatively, if the extension direction of a portion of the protrusion portion 121 is consistent with the circumferential direction a as described above, and the extension direction of another portion of the protrusion portion 121 is consistent with the axis direction b as described above, a portion of the plurality of dust extraction openings 102 are arranged in a direction consistent with the circumferential direction a as described above, and another portion of the plurality of dust extraction openings 102 are arranged in a direction consistent with the axis direction b as described above. Alternatively, the protrusion portion 121 may be extended in a direction angled with the circumferential direction a or the axis direction b according to actual needs, then the plurality of dust extraction openings 102 are arranged according to the extension direction of the protrusion portion 121. Alternatively, the plurality of dust extraction openings 102 may be randomly arranged on the protrusion portion 121.


As shown in FIG. 4, in some embodiments, the sidewall 12 includes a sidewall body 122 and a dust extraction structure 123, the sidewall body 122 is connected to the bottom wall 11 to form the dust collection cavity 103. The sidewall body 122 is provided with a mounting opening 122a, the dust extraction structure 123 is provided with a dust extraction opening 102, and the dust extraction structure 123 is mounted in the mounting opening 122a.


In contrast to the integrated sidewall 12 provided in the previous embodiment, the sidewall 12 provided in the present embodiment includes a sidewall body 122 and a dust extraction structure 123. The dust collection cavity 103 is defined by the sidewall body 122 and the bottom wall 11. The dust extraction structure 123 can be detached from the sidewall body 122 from the mounting opening 122a, or can be mounted to the sidewall body 122 via the mounting opening 122a, for example, the dust extraction structure 123 can be mounted on the mounting opening 122a by a high strength buckle 1242. Of course, the dust extraction structure 123 may also be mounted to the mounting opening 122a by glue.


The dust extraction structure 123 provides a variety of choices for the dust extraction opening 102 for replacing the dust extraction structure 123 to replace the dust extraction opening 102, and also facilitates the selection of the dust extraction structure 123 by different users according to the amount of dust extraction to be performed in different scenarios. And the outside of the dust extraction opening 102 is accompanied by other ancillary structures, such as a rotation cover 131 for closing or opening the dust extraction opening 102. The dust extraction structure 123 can be fitted with the rotation cover 131. The rotation cover 131 is required to open the dust extraction opening 102 under the action of a large suction force, and is driven by the rotation shaft 132 to close the dust extraction opening 102. Along with the increase of the number of use of the rotation cover 131, its failure frequency or damage probability will also increase, and the ancillary structure of the dust extraction opening 102 may be repaired by disassembling the dust extraction structure 123, or the ancillary structure of the dust extraction opening 102 may be replaced by replacing the dust extraction structure 123.


In some embodiments, a portion of the dust extraction structure 123 is fit with the mounting opening 122a, and another portion of the dust extraction structure 123 is provided on an outside of the mounting opening 122a, and the dust extraction opening 102 is provided on the portion of the dust extraction structure 123 provided on the outside of the mounting opening 122a. Preferably, the portion of the dust extraction structure 123 fit with the mounting opening 122a has an inside that is flush with the inside of the mounting opening 122a and does not extend into the space where the dust collection cavity 103 is located. Since the inside of the dust extraction structure 123 is flush with the inside of the mounting opening 122a, it does not occupy the inner space of the dust collection cavity 103, that is, there is no blind angle, inaccessible to the wind path of the dust extraction, formed between the dust extraction structure 123 and the inner wall of the dust collection cavity 103, thereby preventing obstruction in the process that the to-be-collected dust material is extracted out from the dust collection cavity 103, and ensuring that the dust extraction is completed.


The dust extraction opening 102 is provided on the portion of the dust extraction structure 123 that is located outside the mounting opening 122a, so as not to occupy the internal space of the dust collection cavity 103 and to ensure the internal normal use volume of the dust collection cavity 103. Alternatively, the portion of the dust extraction structure 123 fit with the mounting opening 122a may be provided with an additional portion of the cavity as an expansion of the internal normal use space of the dust collection cavity 103, thereby improving the utilization of the internal space of the dust collection cavity 103, and increasing the maximum dust collection volume of the dust collection cavity 103.


In some embodiments, the sidewall 12 includes a plurality of dust extraction structures 123, each of which is provided with a dust extraction opening 102. The plurality of dust extraction openings 102 increase the area for dust extraction, which is conducive to reducing the time that the cleaning base station 10001 sucks dust from the dust extraction openings 102, thereby improving the efficiency of dust suction, and also reducing the loss of use of the cleaning base station 10001.


In this embodiment, the plurality of dust extraction structures 123 are arranged sequentially at intervals. The plurality of dust extraction structures 123 are arranged in a direction consistent with the circumferential direction a as described above. Alternatively, the plurality of dust extraction structures 123 are arranged in a direction consistent with the axis direction b as described above, i.e., perpendicular to the circumferential direction a. Alternatively, a portion of the plurality of dust extraction structures 123 is arranged in a direction consistent with the circumferential direction a as described above, and another portion of the plurality of dust extraction structures 123 is arranged in a direction consistent with the axis direction b as described above. Alternatively, the plurality of dust extraction structures 123 may be flexibly selected and arranged in a direction angled with the circumferential direction a or the axis direction b according to actual needs. Alternatively, the plurality of dust extraction structures 123 may be randomly arranged. In this embodiment, the dust extraction structure 123 is provided with at least one dust extraction opening 102, and the arrangement of all dust extraction openings 102 on the sidewall 12 depends on the arrangement of the dust extraction structures 123, which will not be discussed herein.


In some embodiments, the dust extraction structure 123 is provided with a plurality of dust extraction openings 102. The plurality of dust extraction openings 102 increase the area for dust extraction, which is conducive to reducing the time that the cleaning base station 10001 sucks dust from the dust extraction openings 102, thereby improving the efficiency of dust suction, and also reducing the loss of use of the cleaning base station 10001.


In this embodiment, if the extension direction of the dust extraction structure 123 is consistent with the circumferential direction a as described above, then the plurality of dust extraction openings 102 are preferably arranged in a direction consistent with the circumferential direction a as described above. Alternatively, the extension direction of the dust extraction structure 123 is consistent with the axis direction b as described above, i.e., perpendicular to the circumferential direction a, then the plurality of dust extraction openings 102 are preferably arranged in a direction consistent with the axis direction b as described above. Alternatively, if the extension direction of a portion of the dust extraction structure 123 is consistent with the circumferential direction a as described above, the extension direction of another portion of the dust extraction structure 123 is consistent with the axis direction b as described above, a portion of the plurality of dust extraction openings 102 is arranged in a direction consistent with the circumferential direction a as described above, and another portion of the plurality of dust extraction openings 102 is arranged in a direction consistent with the axis direction b as described above. Alternatively, the dust extraction structure 123 may be extended in a direction angled with the circumferential direction a or the axis direction b according to actual needs, then the plurality of dust extraction openings 102 are arranged in the extension direction of the protrusion portion 121. Alternatively, the plurality of dust extraction openings 102 may be randomly arranged on the dust extraction structure 123.


As shown in FIGS. 9 and 11, in some embodiments, the dust collection cavity 103 includes a first dust collection cavity 103a and a second dust collection cavity 103b in communication with the first dust collection cavity 103a. A portion of the sidewall 12 and the bottom wall 11 form the first dust collection cavity 103a, and another portion of the sidewall 12 and the bottom wall 11 form the second dust collection cavity 103b. A circumference where the portion of the sidewall 12 is located is located on an inside of a circumference where the another portion of the sidewall 12 is located, and the dust extraction opening 102 is provided on the another portion of the sidewall 12.


In this embodiment, the compositional structure of the sidewall 12 may be arbitrary, and the sidewall 12 may be an integrated structure, and the sidewall 12 may be formed by connecting two or more sub-walls. In this embodiment, there is no specific limitation on the form of composition of the sidewall 12, and the sidewall 12 formed in any compositional manner is within the scope of the embodiments of the present application.


In this embodiment, preferably, the volume of the first dust collection cavity 103a is much larger than the volume of the second dust collection cavity 103b, and the extension area of a portion of the sidewall 12 is much larger than the extension area of another portion of the sidewall 12, and the dust extraction opening 102 is provided in another portion of the sidewall 12. Of course, under certain conditions or scenarios, the volume of the first dust collection cavity 103a may be equal to or even less than the volume of the second dust collection cavity 103b, i.e., the extension area of a portion of the sidewall 12 may be equal to or less than the extension area of another portion of the sidewall 12.


If the circumference where a portion of the sidewall 12 is located is located on the inside of the circumference where another portion of the sidewall 12 is located, another portion of the sidewall 12 is protruded outwardly relative to the first dust collection cavity 103a without occupying the internal space of the first dust collection cavity 103a, thereby ensuring the internal normal use volume of the first dust collection cavity 103a. Moreover, since a second dust collection cavity 103b is also provided in another portion of the sidewall 12, the second dust collection cavity 103b serves as an expansion of the internal normal use space of the first dust collection cavity 103a, which improves the utilization rate of the internal space of the first dust collection cavity 103a, and increases the maximum dust collection volume of the dust collection assembly 10.


Based on the above embodiment, the dust collection assembly 10 includes a rotation cover 131 and at least one dust extraction opening 102, that is, the sidewall 12 is provided with one dust extraction opening 102 or a plurality of dust extraction openings 102, the rotation cover 131 is connected to the sidewall 12 and configured to be rotatable relative to the sidewall 12, the rotation cover 131 is provided for closing or opening the at least one dust extraction opening 102, that is, the rotation cover 131 is provided for closing or opening one dust extraction opening 102, or a plurality of dust extraction openings 102 simultaneously.


The rotation cover 131 can switch the dust extraction opening 102 from a closed state to an opened state under the suction force of the dust collection suction generation device, so as to allow the matters in the dust collection cavity 103 to enter the dust collection opening 10002 by the dust extraction opening 102. The rotation cover 131 opens a plurality of dust extraction openings 102 simultaneously, which can allow a plurality of the dust extraction openings 102 to extract dust simultaneously, thereby increasing the efficiency of the dust extraction. Moreover, compared to the embodiment in which one dust extraction opening 102 is fit with one rotation cover 131, one rotation cover 131 is fit with a plurality of dust extraction openings 102, which can ensure the synchronization of dust suction through the plurality of dust extraction openings 102, and can also reduce the number of rotation covers 131 used, and can reduce the adsorption power of the dust collection suction generation device, and thus reduce the energy loss of the dust collection suction generation device.


Of course, in other embodiments, when the sidewall 12 is provided with a plurality of dust extraction openings 102, a portion of the plurality of dust extraction openings 102 may be fit with one rotation cover 131, and another portion of the plurality of dust extraction openings 102 may be fit with another rotation cover 131. That is, the number of rotation covers 131 is reduced because the number of rotation covers 131 is less than the number of dust extraction openings 102.


As shown in FIGS. 3 and 4, in some embodiments, the dust collection assembly 10 further includes a rotation assembly 13 provided outside the sidewall 12. Since the rotation assembly 13 is provided outside the sidewall 12, thus the rotation assembly 13 does not occupy the internal space of the dust collection cavity 103, thereby ensuring the normal use space of the dust collection cavity 103. In addition, the rotation assembly 13 is provided on the outside of the sidewall 12, the functional requirement of keeping the dust extraction opening 102 closed by the rotation assembly 13 during the dust suction of the cleaning device 100 can be satisfied, and the functional requirement of keeping the dust extraction opening 102 open by the rotation assembly 13 during the dust suction of the base station is also satisfied.


As shown in FIGS. 3 and 4, and FIG. 6, the rotation assembly 13 includes a rotation cover 131, a rotation shaft 132, and a first biasing member 133. Based on the rotation assembly 13 provided in the present embodiment, the assembly of the rotation cover 131 and the scheme of realizing the rotation as mentioned in the previous embodiment are described in detail.
