Summary of the Invention

[0021] Optionally, the filter has a notch at the bottom, the notch being located on the side of the filter away from the exhaust port.

[0023] Optionally, in the projection of the main body of the cleaning device along the first direction, the minimum distance between the inner wall of the exhaust duct away from the exhaust port and the outer wall of the filter away from the exhaust port is greater than or equal to 1 mm and less than or equal to 20 mm.

[0024] Optionally, in the projection of the main body of the cleaning device along the first direction, the minimum distance between the inner wall of the exhaust duct away from the exhaust port and the outer wall of the filter away from the exhaust port is greater than or equal to 8 mm and less than or equal to 10 mm.

[0025] Optionally, in the projection of the main body of the cleaning device along the first direction, the minimum distance between the exhaust port and the outer wall of the filter near the exhaust port is greater than or equal to 8 mm.

[0033] Optionally, the exhaust fan further includes:

[0034] The exhaust vent is through which the exhaust fan is connected to the filter.

[0035] Another aspect of this disclosure provides a cleaning device, comprising:

[0036] Cleaning Department;

[0037] The main body of the cleaning equipment is any one of the cleaning equipment main bodies described above, and the cleaning equipment main body is connected to the cleaning unit.

[0038] Another aspect of this disclosure provides a cleaning system, comprising:

[0039] Base station;

[0040] The cleaning equipment is the cleaning equipment described above, and the cleaning equipment is capable of interfacing with the base station.

[0041] The technical solution provided in this disclosure can achieve the following beneficial effects:

[0042] The cleaning equipment provided in this disclosure includes a main body comprising: an exhaust fan, an exhaust duct, and a filter. The exhaust fan may have an exhaust port, which may communicate with a receiving cavity of the exhaust duct, and the filter is disposed within the receiving cavity. The centerline of the filter extending in a first direction is farther from the exhaust port than the centerline of the exhaust duct extending in the first direction; and / or, in a second direction, the centerline of the filter extending in the first direction is separated from the centerline of the exhaust duct extending in the first direction; the first direction is the extension direction of the side plate, and the second direction is perpendicular to both the first and third directions, where the third direction is the direction from the exhaust port to the filter.

[0043] With this configuration, when the center line of the filter extending in the first direction is far from the exhaust port relative to the center line of the exhaust duct extending in the first direction, the filter can be moved forward along a third direction relative to the prior art. When the length of the connecting part between the exhaust fan and the filter remains unchanged, the entire exhaust fan can be moved forward along a third direction, reducing the size of the main body of the cleaning equipment in the third direction.

[0044] Alternatively, when the centerline of the filter extending in the first direction separates from the centerline of the exhaust duct extending in the first direction in the second direction, the filter can be positioned closer to the edge of the exhaust duct near the exhaust fan. This allows for the use of shorter connecting parts to connect the exhaust fan and the filter, and also allows the entire exhaust fan to move forward in the third direction, reducing the size of the cleaning equipment body in the third direction. Simultaneously, the shorter connecting parts reduce manufacturing costs for the cleaning equipment body.

[0045] Alternatively, when the centerline of the filter extending in the first direction is farther from the exhaust port than the centerline of the exhaust duct extending in the first direction, and in the second direction, the centerline of the filter extending in the first direction separates from the centerline of the exhaust duct extending in the first direction, the filter can be moved forward along a third direction. Simultaneously, a shorter connecting component can be used to connect the exhaust fan and the filter, further allowing the entire exhaust fan to move forward along a third direction, further reducing the size of the cleaning equipment body in the third direction. At the same time, the shorter connecting component also saves on the manufacturing cost of the cleaning equipment body.

[0046] Therefore, all three methods mentioned above can reduce the size of the main body of the cleaning equipment in the third direction, which enables the main body of the cleaning equipment to be miniaturized, and thus enables the cleaning equipment equipped with the main body of the cleaning equipment to be miniaturized.

[0047] Furthermore, since this disclosure achieves the miniaturization of the cleaning equipment by miniaturizing the main body of the cleaning equipment, it does not require reducing the volume of the cleaning part compared to the prior art, and therefore does not affect the cleaning effect of the cleaning equipment.

[0048] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0061] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0062] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." 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.

[0063] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0064] As shown in Figures 1 to 7, this disclosure first provides a cleaning equipment body 221. The cleaning equipment body 221 can be a vacuum cleaner body, a floor scrubber body, a sweeper body, etc. The cleaning equipment body 221 may include: an exhaust fan 1, an exhaust duct 2, and a filter 3.

[0065] As shown in Figures 3 to 5, the exhaust fan 1 may have an exhaust port 12 and an exhaust port 11. The exhaust fan 1 can communicate with the filter 3 through the exhaust port 12 to extract air from the filter 3. The exhaust duct 2 may include a side plate 21 and a receiving cavity 22. The side plate 21 can form the receiving cavity 22, and the exhaust port 11 can communicate with the receiving cavity 22. The air extracted by the exhaust fan 1 can be discharged into the receiving cavity 22 through the exhaust port 11 and then discharged into the external environment through the exhaust duct 2. The filter 3 can be set in the receiving cavity 22 to filter impurities, preventing impurities from being extracted by the exhaust fan 1 and damaging the exhaust fan 1, and also preventing impurities from being discharged into the external environment and reducing the cleaning effect.

[0066] The side wall can also be provided with an air outlet 26, which can be connected to the exhaust port 12 of the exhaust fan 1. The air in the filter 3 can enter the exhaust fan 1 through the air outlet 26 and then through the exhaust port 12.

[0067] Optionally, referring to Figure 1, the center line S2 of the filter 3 extending along the first direction X can be moved away from the exhaust port 11 relative to the center line S1 of the exhaust duct 2 extending along the first direction X. Here, the first direction X can be the extension direction of the side plate 21. With this configuration, when the center line S2 of the filter 3 extending along the first direction X is moved away from the exhaust port 11 relative to the center line S1 of the exhaust duct 2 extending along the first direction X, the filter 3 can be moved forward along the third direction Z relative to the prior art. When the length of the connecting component between the exhaust fan 1 and the filter 3 remains unchanged, the entire exhaust fan 1 can be moved forward along the third direction Z, reducing the size of the cleaning equipment body in the third direction Z.

[0068] Alternatively, referring to Figure 2, in the second direction Y, the centerline S2 of the filter 3 extending along the first direction X can be separated from the centerline S1 of the exhaust duct 2 extending along the first direction X. The second direction Y can be perpendicular to both the first direction X and the third direction Z, where the third direction Z can be the direction in which the exhaust port 11 points towards the filter 3. This arrangement allows the filter 3 to be closer to the edge of the exhaust duct 2 near the exhaust fan 1, enabling the use of shorter connecting parts to connect the exhaust fan 1 and the filter 3. This also allows the entire exhaust fan 1 to move forward along the third direction Z, reducing the size of the cleaning equipment body in the third direction Z. Simultaneously, the shorter connecting parts reduce the manufacturing cost of the cleaning equipment body.

[0069] Alternatively, referring to Figure 2, the centerline S2 of the filter 3 extending along the first direction X can be moved away from the exhaust port 11 relative to the centerline S1 of the exhaust duct 2 extending along the first direction X, and in the second direction Y, the centerline S2 of the filter 3 extending along the first direction X can be separated from the centerline S1 of the exhaust duct 2 extending along the first direction X. This arrangement allows the filter 3 to move forward along the third direction Z, and simultaneously allows for the use of shorter connecting parts to connect the exhaust fan 1 and the filter 3, thereby further allowing the entire exhaust fan 1 to move forward along the third direction Z, further reducing the size of the cleaning equipment body in the third direction Z. At the same time, the shorter connecting parts also save on the manufacturing cost of the cleaning equipment body.

[0070] As can be seen from the above, all of the above-mentioned optional solutions can reduce the size of the main body of the cleaning equipment in the third direction Z, which can make the main body of the cleaning equipment miniaturized, and thus make the cleaning equipment equipped with the main body of the cleaning equipment miniaturized.

[0071] Furthermore, since this disclosure achieves the miniaturization of the cleaning equipment by miniaturizing the main body of the cleaning equipment, it does not require reducing the volume of the cleaning part 8 compared to the prior art, and thus does not affect the cleaning effect of the cleaning equipment.

[0072] Optionally, as shown in Figure 5, in the projection of the main body of the cleaning equipment along the first direction X, the minimum distance L1 between the inner wall of the exhaust duct 2 away from the exhaust port 11 and the outer wall of the filter 3 away from the exhaust port 11 can be greater than or equal to 1 mm and less than or equal to 20 mm. For example, the minimum distance L1 between the inner wall of the exhaust duct 2 away from the exhaust port 11 and the outer wall of the filter 3 away from the exhaust port 11 can be: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, etc.

[0073] This design ensures sufficient airflow space between the inner wall of the exhaust duct 2 and the outer wall of the filter 3, preventing excessive air resistance caused by insufficient airflow space. This guarantees the effective exhaust of the fan 1 and consequently, the cleaning performance of the cleaning equipment. Furthermore, this design also prevents an excessively large distance between the inner wall of the exhaust duct 2 and the outer wall of the filter 3, which could negatively impact the miniaturization of the cleaning equipment.

[0074] Optionally, in the projection of the main body of the cleaning equipment along the first direction X, the minimum distance L1 between the inner wall of the exhaust duct 2 away from the exhaust port 11 and the outer wall of the filter 3 away from the exhaust port 11 can be greater than or equal to 8 mm and less than or equal to 10 mm. For example, the minimum distance L1 between the inner wall of the exhaust duct 2 away from the exhaust port 11 and the outer wall of the filter 3 away from the exhaust port 11 can be 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0075] This design ensures sufficient airflow between the inner wall of the exhaust duct 2 and the outer wall of the filter 3, preventing excessive air resistance due to insufficient airflow between them. This enhances the suction effect of the exhaust fan 1 and consequently, the cleaning performance of the cleaning equipment. Furthermore, this design also prevents excessive distance between the inner wall of the exhaust duct 2 and the outer wall of the filter 3 from negatively impacting the miniaturization of the cleaning equipment.

[0076] Optionally, as shown in Figure 5, in the projection of the main body of the cleaning equipment along the first direction X, the minimum distance L2 between the exhaust port 11 and the outer wall of the filter 3 near the exhaust port 11 can be greater than or equal to 8mm, for example: 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc. This setting can avoid the distance between the exhaust port 11 and the filter 3 being too close, thus avoiding excessive wind resistance between the exhaust port 11 and the filter 3, thereby ensuring that the airflow can flow smoothly between the exhaust port 11 and the filter 3, and thus ensuring the exhaust effect of the exhaust fan 1, and therefore ensuring the cleaning effect of the cleaning equipment.

[0077] Optionally, as shown in Figure 1, the distance L3 between the center line of the filter 3 extending along the first direction X and the center line of the exhaust duct 2 extending along the first direction X can be 2mm to 6mm, for example: 2mm, 3mm, 4mm, 5mm, 6mm, etc. This setting allows the filter 3 to move forward a sufficient distance along the third direction Z, and the entire exhaust fan 1 to move forward a sufficient distance along the third direction Z, ensuring the miniaturization of the main body of the cleaning equipment. Furthermore, this setting also avoids the distance between the filter 3 and the inner wall of the exhaust duct 2 becoming too small due to excessive forward movement of the filter 3, thus further ensuring that airflow can flow smoothly between the exhaust port 11 and the filter 3, thereby further ensuring the exhaust effect of the exhaust fan 1.

[0078] Optionally, as shown in Figures 4 and 5, the exhaust duct 2 may further include an air inlet 23. The air inlet 23 may be disposed on the side plate 21, and the air inlet 23 may be located between the filter 3 and the exhaust port 11. The exhaust port 11 may be connected to the air inlet 23. That is, the exhaust fan 1 can exhaust the extracted air from the exhaust port 11 through the air inlet 23 into the receiving cavity 22.

[0079] Optionally, in the projection of the main body of the cleaning equipment along the first direction X, the minimum distance L4 between the air inlet 23 and the outer wall of the filter 3 near the air inlet 23 can be greater than or equal to 8mm, for example: 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc. This setting ensures that the air inlet 23 and the filter 3 have sufficient distance, which reduces the air resistance between the air inlet 23 and the filter 3, thereby improving the airflow efficiency within the receiving cavity 22, thus improving the exhaust effect of the exhaust duct 2, and consequently improving the cleaning effect of the cleaning equipment.

[0080] Optionally, the center line S6 of the exhaust fan 1 extending in the third direction Z can be perpendicular to the center line S2 of the filter 3 extending in the first direction X. This arrangement can improve the exhaust efficiency of the exhaust fan 1, thereby enhancing the cleaning effect of the cleaning equipment.

[0081] Optionally, as shown in Figure 5, at least a portion of the exhaust fan 1 can be located within the exhaust duct 2. Within the exhaust duct 2, the portion of the side plate 21 located between the filter 3 and the exhaust port 11 can have a recess 24, within which at least a portion of the exhaust fan 1 can be located. This arrangement provides a space for the exhaust fan 1 to be installed and accommodated using the recess 24.

[0082] Furthermore, because the filter 3 is moved forward, when the exhaust fan 1 is located inside the recess 24, the distance between the exhaust fan 1 and the filter 3 can remain unchanged, so as not to affect the exhaust effect of the exhaust fan 1, and thus not to affect the cleaning effect of the cleaning equipment.

[0083] Meanwhile, this design avoids the problem of the exhaust fan 1 needing to extend into the receiving cavity 22 to maintain a constant distance between the exhaust fan 1 and the filter 3. Therefore, it eliminates the need for a through hole on the side plate 21 large enough for the exhaust fan 1 to extend into the receiving cavity 22, thus preserving the integrity of the side plate 21 as much as possible. This ensures that the airflow can form a cyclone within the receiving cavity 22, thereby guaranteeing the exhaust effect of the exhaust fan 1. Furthermore, this design improves the structural strength of the side plate 21, thereby extending the service life of the exhaust duct 2 and the entire cleaning equipment body.

[0084] Optionally, the air inlet 23 can be located in the recess 24 so that the exhaust port 11 located in the recess 24 can communicate with the receiving cavity 22 through the air inlet 23.

[0085] Optionally, in the third direction Z, the depth H1 of the recess 24 can be greater than or equal to 1 mm and less than or equal to 20 mm. For example, the depth H1 of the recess 24 can be: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, etc. This setting corresponds to the forward movement of the filter 3, ensuring that the distance between the exhaust port 11 and the filter 3 remains constant, and that the length of the component connecting the exhaust fan 1 and the filter 3 remains constant. Furthermore, it provides sufficient redundant setting space for the exhaust fan 1, allowing the operator to freely adjust the distance between the exhaust port 11 and the filter 3 within this redundant setting space as needed.

[0086] Optionally, in the third direction Z, the depth H1 of the recess 24 can be greater than or equal to 8 mm and less than or equal to 10 mm. For example, the depth H1 of the recess 24 can be 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc. This setting corresponds to the forward movement distance of the filter 3, ensuring that the distance between the exhaust port 11 and the filter 3 remains constant, and that the length of the component connecting the exhaust fan 1 and the filter 3 remains constant. Furthermore, this setting provides sufficient redundant setting space for the exhaust fan 1, allowing operators to freely adjust the distance between the exhaust port 11 and the filter 3 within this redundant setting space as needed.

[0087] Optionally, as shown in Figures 1 and 5, the main body 221 of the cleaning equipment may further include a dust bin 4. The dust bin 4 may be located on one side of the exhaust duct 2 in the first direction X, and the dust bin 4 may be connected to the exhaust duct 2. The dust bin 4 may be used to collect dirt and impurities sucked out by the cleaning unit 8.

[0088] Optionally, the centerline S2 of the filter 3 extending along the first direction X can be located away from the exhaust port 11 relative to the centerline S3 of the dust bin 4 extending along the first direction X; and / or, in the second direction Y, the centerline S2 of the filter 3 extending along the first direction X can be separated from the centerline S3 of the dust bin 4 extending along the first direction X. This arrangement allows for a further reduction in the size of the cleaning equipment body in the third direction Z, thereby further improving the miniaturization of the cleaning equipment body.

[0089] The main body 221 of the cleaning equipment may also include a cyclone separator 5. The cyclone separator 5 may be installed inside the dust bin 4 and connected to the filter 3 to sieve the dirty air drawn in by the main body of the cleaning equipment, so that the dirt enters the dust bin 4 and the sieved air enters the filter 3.

[0090] The center line S2 of filter 3 extending in the first direction X is far away from the exhaust port 11 relative to the center line S4 of cyclone separator 5 extending in the first direction X; and / or, in the second direction Y, the center line S2 of filter 3 extending in the first direction X can be separated from the center line S4 of cyclone separator 5 extending in the first direction X.

[0091] Optionally, the center line S3 of the dust bin 4 extending along the first direction X can coincide with the center line S4 of the cyclone separator 5 extending along the first direction X. This arrangement ensures that the distance between the cyclone separator 5 and the inner wall of the dust bin 4 is equal everywhere, ensuring the airflow of the cyclone separator 5, making the cyclone formed more stable, and ensuring its effect in screening dirt.

[0092] Optionally, the center line S1 of the exhaust duct 2 extending along the first direction X can coincide with the center line S4 of the cyclone separator 5 extending along the first direction X. This arrangement facilitates the installation of the cyclone separator 5.

[0093] Optionally, the orthographic projection of the dustbin 4 in the first direction X can coincide with the orthographic projection of the exhaust duct 2 in the first direction X. This arrangement facilitates the connection between the dustbin 4 and the exhaust duct 2, and also facilitates the installation of other components in the main body of the cleaning equipment.

[0094] As shown in Figures 1, 2, and 5, a filter cover 25 can be installed on the side of the exhaust duct 2 away from the dust bin 4, allowing air in the receiving cavity 22 to enter the external environment through the filter cover 25. By installing the filter cover 25, impurities from the external environment can be prevented from entering the receiving cavity 22 and causing air duct blockage, or impurities from the external environment can be prevented from entering the receiving cavity 22 and causing damage to the exhaust fan 1.

[0095] The center line S2 of filter 3 extending in the first direction X is away from the exhaust port 11 relative to the center line S5 of filter cover 25 extending in the first direction X; and / or, in the second direction Y, the center line S2 of filter 3 extending in the first direction X is separated from the center line S5 of filter cover 25 extending in the first direction X.

[0096] Furthermore, the center line S2 of the filter cover 25 extending along the first direction X can coincide with the center line S1 of the exhaust duct 2 along the first direction X. This arrangement facilitates the installation of the filter cover 25.

[0097] Optionally, the filter 3 can be installed at the end of the exhaust duct 2 away from the dust bin 4. This arrangement facilitates the removal and installation of the filter 3 and avoids positional interference between the filter 3 and the dust bin 4 during installation.

[0098] As shown in Figure 6, the bottom of the filter 3 may have a notch 33. It can be understood that the notch 33 may be located at the end of the filter 3 near the dust bin 4. The notch 33 is located on the side of the filter 3 away from the exhaust port 11, which makes the notch 33 located on the opposite side of the exhaust port 12 of the exhaust fan 1. The distance between the notch 33 and the exhaust port 12 is large, which can reduce its impact on the wind resistance of the air entering the exhaust fan 1 and ensure the exhaust effect of the exhaust fan 1.

[0099] Furthermore, the center line S2 of the filter 3 extending along the first direction X can coincide with the center line of the annular limiting groove 71 extending along the first direction X, so as to improve the limiting ability of the annular limiting groove 71 on the filter 3.

[0100] As shown in Figure 5, the filter 3 may include a support portion 31 and a filter screen 32. The support portion 31 may be installed at the end of the exhaust duct 2 away from the dust bin 4, and the filter screen 32 may be installed on the support portion 31 to filter dirt and impurities.

[0101] Optionally, as shown in Figures 1, 2, and 5 to 7, the main body 221 of the cleaning equipment may include a support frame 7 and a power source 6. The exhaust duct 2 and dust bin 4 can be mounted on the support frame 7, and the power source 6 can be detachably mounted on the support frame 7. The power source 6 may include the aforementioned exhaust fan 1. This configuration facilitates the installation and removal of the exhaust fan 1, allowing operators to replace it with exhaust fans of different power or type as needed.

[0102] Optionally, as shown in Figure 7, an annular limiting groove 71 is provided on the side of the support frame 7 near the filter 3. The bottom wall of the filter 3 can be fitted into the annular limiting groove 71 to limit its movement. The center line of the annular limiting groove 71 extending along the first direction X is farther away from the exhaust port 11 relative to the center line S3 of the dust bin 4 extending along the first direction X; and / or, in the second direction Y, the center line of the annular limiting groove 71 extending along the first direction X is separated from the center line S3 of the dust bin 4 extending along the first direction X.

[0103] Optionally, the power source 6 may further include a battery 61. With this configuration, the main body of the cleaning equipment provided by this disclosure can directly provide power to the exhaust fan 1 via the battery 61, thus eliminating the need for additional wiring to connect to an external power source. Therefore, the main body of the cleaning equipment provided by this disclosure is no longer constrained by the length of the wiring and the location of the external power source during use, thereby improving the ease of use of the cleaning equipment.

[0104] Optionally, since the power source 6 includes the aforementioned exhaust fan 1, when the exhaust fan 1 moves forward along the third direction Z, the entire power source 6 can move forward along the third direction Z, thereby effectively reducing the size of the main body of the cleaning equipment in the third direction Z, which allows the main body of the cleaning equipment to be further miniaturized, and thus the cleaning equipment equipped with the main body of the cleaning equipment to be further miniaturized.

[0105] This disclosure also provides a cleaning device. This cleaning device can be a vacuum cleaner, floor scrubber, sweeper, etc.

[0106] As shown in Figures 1 to 7, the cleaning device 220 may include a cleaning unit 8 and a cleaning device body 221. The cleaning unit 8 is used to contact the surface to be cleaned, and cleans dirt from the surface under the drive of the cleaning device body. For example, when the cleaning device is a vacuum cleaner, the cleaning unit 8 may be the vacuum cleaner head or a connecting rod linking the head to the cleaning device body.

[0107] The main body of the cleaning equipment can be the cleaning equipment body described above, and the cleaning equipment body can be connected to the cleaning unit 8.

[0108] It should be noted that the specific structure and beneficial effects of the main body of the cleaning equipment have been described in detail in the above optional solutions, so the specific structure and beneficial effects of the main body of the cleaning equipment will not be repeated here. You can refer to the specific description of the above optional solutions, which are all within the protection scope of this disclosure.

[0109] The cleaning device 220 provided in this disclosure includes the cleaning device body 221 described above. The cleaning device body 221 includes: an exhaust fan 1, an exhaust duct 2, and a filter 3. The exhaust fan 1 may have an exhaust port 11, which may communicate with the filter 3. The filter 3 is disposed within a receiving cavity 22. The centerline S2 of the filter 3 extending along a first direction X is farther from the exhaust port 11 than the centerline S1 of the exhaust duct 2 extending along the first direction X; and / or, in a second direction Y, the centerline S2 of the filter 3 extending along the first direction X is separated from the centerline S1 of the exhaust duct 2 extending along the first direction X. The first direction X is the extension direction of the side plate 21, and the second direction Y is perpendicular to the first direction X and a third direction Z, where the third direction Z is the direction from the exhaust port 11 to the filter 3.

[0110] With this configuration, when the center line S2 of the filter 3 extending along the first direction X is far away from the exhaust port 11 relative to the center line S1 of the exhaust duct 2 extending along the first direction X, the filter 3 can be moved forward along the third direction Z relative to the prior art. When the length of the connecting part between the exhaust fan 1 and the filter 3 remains unchanged, the entire exhaust fan 1 can be moved forward along the third direction Z, reducing the size of the main body of the cleaning equipment in the third direction Z.

[0111] Alternatively, when the centerline S2 of filter 3 extending along the first direction X is separated from the centerline S1 of exhaust duct 2 extending along the first direction X in the second direction Y, filter 3 can be moved closer to the edge of exhaust duct 2 near the exhaust fan 1. This allows for the use of a shorter connecting component to connect the exhaust fan 1 and filter 3, and also allows the entire exhaust fan 1 to move forward in the third direction Z, reducing the size of the cleaning equipment body in the third direction Z. Simultaneously, the shorter connecting component reduces the manufacturing cost of the cleaning equipment body.

[0112] Alternatively, when the center line S2 of filter 3 extending along the first direction X is far from the exhaust port 11 relative to the center line S1 of exhaust duct 2 extending along the first direction X, and in the second direction Y, the center line S2 of filter 3 extending along the first direction X is separated from the center line S1 of exhaust duct 2 extending along the first direction X, filter 3 can be moved forward along the third direction Z. At the same time, a shorter connecting part can be used to connect exhaust fan 1 and filter 3, thereby further moving the entire exhaust fan 1 forward along the third direction Z, further reducing the size of the cleaning equipment body in the third direction Z. Simultaneously, due to the shorter connecting part, the manufacturing cost of the cleaning equipment body can also be saved.

[0113] Therefore, all three methods mentioned above can reduce the size of the main body of the cleaning equipment in the third direction Z, which enables the main body of the cleaning equipment to be miniaturized, and thus enables the miniaturization of the cleaning equipment.

[0114] Furthermore, since this disclosure achieves the miniaturization of the cleaning equipment by miniaturizing the main body of the cleaning equipment, it does not require reducing the volume of the cleaning section 8 compared to the prior art, and thus does not affect the cleaning effect of the cleaning equipment.

[0115] As shown in Figure 8, this disclosure also provides a cleaning system 1000. The cleaning system 1000 may include a base station 110 and a cleaning device 220. The cleaning device may be the cleaning device described above, and the cleaning device is capable of interfacing with the base station.

[0116] It should be noted that the specific structure and beneficial effects of the main body of the cleaning equipment have been described in detail in the above optional solutions, so the specific structure and beneficial effects of the main body of the cleaning equipment will not be repeated here. You can refer to the specific description of the above optional solutions, which are all within the protection scope of this disclosure.

[0117] The cleaning system provided in this disclosure includes the cleaning equipment described above, as shown in Figures 1 to 3. The cleaning equipment 220 includes the cleaning equipment body 221 described above, which includes an exhaust fan 1, an exhaust duct 2, and a filter 3. The exhaust fan 1 may have an exhaust port 11, which may communicate with the filter 3, which is disposed within a receiving cavity 22. In the first direction X, the center line S2 of the filter 3 extending along the second direction Y is farther from the exhaust port 11 relative to the center line S1 of the exhaust duct 2 extending along the second direction Y.

[0118] Wherein, the center line S2 of the filter 3 extending along the first direction X is farther away from the exhaust port 11 relative to the center line S1 of the exhaust duct 2 extending along the first direction X; and / or, in the second direction Y, the center line S2 of the filter 3 extending along the first direction X is separated from the center line S1 of the exhaust duct 2 extending along the first direction X; the first direction X is the extension direction of the side plate 21, the second direction Y is perpendicular to the first direction X and the third direction Z, and the third direction Z is the direction in which the exhaust port 11 points to the filter 3.

[0119] With this configuration, when the center line S2 of the filter 3 extending along the first direction X is far away from the exhaust port 11 relative to the center line S1 of the exhaust duct 2 extending along the first direction X, the filter 3 can be moved forward along the third direction Z relative to the prior art. When the length of the connecting part between the exhaust fan 1 and the filter 3 remains unchanged, the entire exhaust fan 1 can be moved forward along the third direction Z, reducing the size of the main body of the cleaning equipment in the third direction Z.

[0120] Alternatively, when the centerline S2 of filter 3 extending along the first direction X is separated from the centerline S1 of exhaust duct 2 extending along the first direction X in the second direction Y, filter 3 can be moved closer to the edge of exhaust duct 2 near the exhaust fan 1. This allows for the use of a shorter connecting component to connect the exhaust fan 1 and filter 3, and also allows the entire exhaust fan 1 to move forward in the third direction Z, reducing the size of the cleaning equipment body in the third direction Z. Simultaneously, the shorter connecting component reduces the manufacturing cost of the cleaning equipment body.

[0121] Alternatively, when the center line S2 of filter 3 extending along the first direction X is far from the exhaust port 11 relative to the center line S1 of exhaust duct 2 extending along the first direction X, and in the second direction Y, the center line S2 of filter 3 extending along the first direction X is separated from the center line S1 of exhaust duct 2 extending along the first direction X, filter 3 can be moved forward along the third direction Z. At the same time, a shorter connecting part can be used to connect exhaust fan 1 and filter 3, thereby further moving the entire exhaust fan 1 forward along the third direction Z, further reducing the size of the cleaning equipment body in the third direction Z. Simultaneously, due to the shorter connecting part, the manufacturing cost of the cleaning equipment body can also be saved.

[0122] Therefore, all three methods mentioned above can reduce the size of the main body of the cleaning equipment in the third direction Z, which enables the main body of the cleaning equipment to be miniaturized, and thus enables the cleaning equipment equipped with the main body of the cleaning equipment to be miniaturized.

[0123] Furthermore, since this disclosure achieves the miniaturization of the cleaning equipment by miniaturizing the main body of the cleaning equipment, it does not require reducing the volume of the cleaning section 8 compared to the prior art, and thus does not affect the cleaning effect of the cleaning system.

[0124] Optionally, when the cleaning equipment is connected to the base station, the base station can charge the cleaning equipment, and / or, when the cleaning equipment is connected to the base station, the base station can suck out the dirt stored in the cleaning equipment and clean the cleaning equipment.

This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
