[0020] In this field, vacuum cleaners and various cleaning devices with dust collection capabilities typically include a fan to power the dust collection operation and a dust collection bucket for collecting debris.

[0021] In some related technologies, during the use of a vacuum cleaner, the vacuuming unit is usually removed from the dust collection bucket to clean the debris in the bucket. When cleaning the debris in the dust collection bucket, the cyclone drum barrel and / or filter assembly are usually removed from the dust collection bucket to easily clean the debris in the dust collection bucket. After cleaning is complete, the user may forget to reattach the cyclone drum barrel and / or filter assembly and instead attach the vacuuming unit directly to the dust collection bucket, which can result in product malfunction and affect product performance and lifespan.

[0022] This disclosure provides a vacuum cleaner comprising: a dust collection body configured to provide power for a dust collection operation; a dust collection bucket detachably attached to the dust collection body and configured to collect dust under the operation of the dust collection body; and a misassembly prevention assembly provided in the dust collection bucket and configured to be switchable between a normal working position and an abnormal working position, wherein the dust collection body can be assembled into the dust collection bucket when the misassembly prevention assembly is in the normal working position, and the dust collection body cannot be assembled into the dust collection bucket when the misassembly prevention assembly is in the abnormal working position.

[0023] An embodiment of the present disclosure provides a misassembly prevention assembly in the dust collection bucket of a vacuum cleaner, which works in cooperation with a cyclone drum barrel and / or filter assembly attached to the dust collection bucket so that the dust collection body can be assembled into the dust collection bucket only when the cyclone drum and / or filter assembly is correctly attached to the dust collection bucket, thereby preventing the user from forgetting to attach the cyclone drum and / or filter assembly and causing a malfunction of the vacuum cleaner. By providing a mechanical misassembly prevention assembly in the dust collection bucket, the present disclosure offers a simple structure, eliminates the need for a control circuit, reduces costs, and improves reliability.

[0024] Selective embodiments of this disclosure will be described in detail below with reference to the attached drawings.

[0025] Figure 1 is a schematic diagram of the structure of a vacuum cleaner provided by some embodiments of the present disclosure. Referring to Figure 1, some embodiments of the present disclosure provide a vacuum cleaner 10, the vacuum cleaner 10 comprising a dust collection bucket 100, a dust collection body 200, and an anti-misassembly assembly. Here, the dust collection bucket 100 is detachably attached to the dust collection body 200, the dust collection body 200 is used to provide power for the dust collection operation, and the dust collection bucket 100 is used to collect dust under the power provided by the dust collection body 200. An anti-misassembly assembly is provided on the dust collection bucket 100 and is configured to be switchable between a normal working position and an abnormal working position, so that when the anti-misassembly assembly is in the normal working position the dust collection body can be assembled into the dust collection bucket, and when the anti-misassembly assembly is in the abnormal working position the dust collection body cannot be assembled into the dust collection bucket. Therefore, it is possible to prevent users from forgetting to install assemblies in the dust collection bucket, such as the cyclone drum and / or filter assembly, which could cause malfunctions in the vacuum cleaner. The mis-assembly prevention assembly includes the first mis-assembly prevention assembly and the second mis-assembly prevention assembly described below.

[0026] Figure 2 is a schematic diagram of the structure of a dust collection bucket provided by some embodiments of the present disclosure, in which a cyclone drum is provided inside the dust collection bucket and a filter assembly is not assembled, as shown in the figure. Referring to Figure 2, the dust collection bucket 100 further includes a dust collection bucket body 110, a cyclone drum 120, and a first misassembly prevention member 130. Here, the cyclone drum 120 is detachably attached to the dust collection bucket body 110, and the outer diameter of the cyclone drum 120 is slightly smaller than the inner diameter of the dust collection bucket body 110, so that the cyclone drum 120 can be fitted inside the dust collection bucket body 110.

[0027] Figure 3 is a schematic diagram of the structure of a dust collection bucket when the first misassembly prevention member provided in some embodiments of the present disclosure is in a first working position. Figure 4 is a schematic diagram of the structure of a dust collection bucket when the first misassembly prevention member provided in some embodiments of the present disclosure is in a second working position. Figure 5 is a schematic diagram of the structure of a cyclone drum provided in some embodiments of the present disclosure. Referring to Figures 2 to 5, in some embodiments, the first misassembly prevention member 130 is provided on the inner wall of the dust collection bucket 100, specifically on the inner wall of the dust collection bucket 100 facing the dust collection body 200.

[0028] The first misassembly prevention member 130 is used to ensure the assembly of the dust collection bucket 100 and the dust collection body 200, and to prevent an incorrect assembly state caused by the failure to install the cyclone drum 120 inside the dust collection bucket 100. Specifically, the first misassembly prevention member 130 is switched between a first working position and a second working position, the first working position being the normal working position and the second working position being the abnormal working position. When the first misassembly prevention member 130 is in the first working position, the dust collection body 200 can be assembled into the dust collection bucket body 110, but when the first misassembly prevention member 130 is in the second working position, the dust collection body 200 cannot be assembled into the dust collection bucket body 110.

[0029] In some embodiments, the first misassembly prevention member 130 works in cooperation with the cyclone drum 120 so that when the cyclone drum 120 is attached to the dust collection bucket body 110, the first misassembly prevention member 130 is switched from a second working position to a first working position, at which time the dust collection body 200 is assembled to the dust collection bucket body 110. When the cyclone drum 120 is removed from the dust collection bucket body 110, the first misassembly prevention member 130 is switched from a first working position to a second working position, at which time the dust collection body 200 cannot be assembled to the dust collection bucket body 110.

[0030] Through the cooperation of the first misassembly prevention member 130 and the cyclone drum 120, the dust collection body 200 can only be assembled to the dust collection bucket body 110 if the cyclone drum 120 is correctly attached to the dust collection bucket body 110, thereby preventing the user from forgetting to attach the cyclone drum 120 and causing malfunctions in the operation of the vacuum cleaner 10.

[0031] In some embodiments, the cooperation between the first misassembly prevention member 130 and the cyclone drum 120 is achieved by spring compression.

[0032] Specifically, a first elastic member 140 is provided on the inner wall of the dust collection bucket body 110, and the first elastic member 140 biases the first mis-assembly prevention member 130 toward the second working position. That is, under the action of the elastic force of the first elastic member 140, the first mis-assembly prevention member 130 tends to move toward the second working position, and when the first mis-assembly prevention member 130 is subjected only to the elastic force of the first elastic member 140 without being subjected to any other external force, the first mis-assembly prevention member 130 is in the second working position. In some embodiments, the first elastic member 140 is a torsion spring.

[0033] In some embodiments, the first misassembly prevention member 130 further includes a first arm 131, a second arm 132, and a first pivot shaft 133. The first misassembly prevention member 130 pivots along the first pivot shaft 133 in a plane parallel to the axis A of the dust collection bucket 100 and is switched between a first working position and a second position. The first arm 131 and the second arm 132 are formed at a predetermined narrow angle, the narrow angle range being, for example, 15° to 175°.

[0034] The cyclone drum 120 includes a contact portion 121 and a notch 122 adjacent to the contact portion 121. During the process of attaching the cyclone drum 120 to the dust collection bucket body 110, the contact portion 121 presses against the first arm 131, the contact point between the contact portion 121 and the first arm 131 moves from the free end 1311 of the first arm 131 toward the second arm 132, the second arm 132 is housed in the notch 122, and the first mis-assembly prevention member 130 is switched from the second working position to the first working position.

[0035] Figure 6 is a schematic diagram of the structure of a filter assembly provided by some embodiments of the present disclosure. Figure 7 is a schematic diagram of the structure of a dust collection bucket to which a filter assembly provided by some embodiments of the present disclosure is attached. Figure 8 is a localized enlarged schematic diagram of Figure 2. Figure 9 is a schematic diagram of the structure of a dust collection body provided by some embodiments of the present disclosure.

[0036] Referring to Figures 6 to 9, in some embodiments, the vacuum cleaner 10 further includes a filter assembly 300, which is detachably attached to the cyclone drum 120. In some embodiments, the cyclone drum 120 has a mounting groove for housing the filter assembly 300. Specifically, the mounting groove forms a housing space for housing the filter assembly 300, and the filter assembly 300 is fitted into the housing space of the mounting groove.

[0037] In some embodiments, the dust collection bucket 100 further includes a second misassembly prevention member 150. For example, the second misassembly prevention member 150 is provided on the inner wall of the cyclone drum 120, specifically on the inner wall of the cyclone drum 120 facing the dust collection body 200.

[0038] The second misassembly prevention member 150 is used to ensure the assembly of the dust collection bucket 100 and the dust collection body 200, and to prevent an incorrect assembly state caused by the failure to install the filter assembly 300 inside the dust collection bucket 100. Specifically, referring to Figure 8, the second misassembly prevention member 150 is switched between a third working position and a fourth working position, with the third working position being the normal working position and the fourth working position being the abnormal working position. When the second misassembly prevention member 150 is in the third working position, the dust collection body 200 can be assembled into the dust collection bucket body 110 to which the cyclone drum 120 is attached, but when the second misassembly prevention member 150 is in the fourth working position, the dust collection body 200 cannot be assembled into the dust collection bucket body 110 to which the cyclone drum 120 is not attached.

[0039] In some embodiments, the second misassembly prevention member 150 works in cooperation with the filter assembly 300 so that when the filter assembly 300 is attached to the cyclone drum 120, the second misassembly prevention member 150 is switched from a fourth working position to a third working position, at which point the dust collection body 200 can be assembled to the dust collection bucket body 110. When the filter assembly 300 is removed from the cyclone drum 120, the second misassembly prevention member 150 is switched from a third working position to a fourth working position, at which point the dust collection body 200 cannot be assembled to the dust collection bucket body 110.

[0040] Through the cooperation of the second misassembly prevention member 150 and the filter assembly 300, the dust collection body 200 can only be assembled to the dust collection bucket body 110 if the filter assembly 300 is correctly attached to the cyclone drum 120, thereby preventing the user from forgetting to attach the filter assembly 300 and causing malfunctions in the vacuum cleaner 10.

[0041] In some embodiments, the cooperation between the second misassembly prevention member 150 and the filter assembly 300 can be achieved by spring compression.

[0042] Specifically, a second elastic member is provided on the inner wall of the cyclone drum 120, and the second elastic member biases the second misassembly prevention member 150 toward the fourth working position. That is, under the action of the elastic force of the second elastic member, the second misassembly prevention member 150 tends to move toward the fourth working position, and the second misassembly prevention member 150 is in the fourth working position when it is subjected only to the elastic force of the second elastic member and not to any other external forces. In some embodiments, the second elastic member is a torsion spring.

[0043] Referring to Figure 6, the filter assembly 300 includes a pressing member 310, which works in cooperation with the second misassembly prevention member 150 to ensure the assembly of the dust collection body 200. When the filter assembly 300 is attached to the cyclone drum 120, the pressing member 310 presses against the second misassembly prevention member 150, causing the second misassembly prevention member 150 to switch from a fourth working position to a third working position. Specifically, after the filter assembly 300 is attached to the cyclone drum 120, the pressing member 310 generates a pressing force against the second misassembly prevention member 150, which at least partially counteracts the elastic force generated by the second elastic member in the second misassembly prevention member 150, preventing the second misassembly prevention member 150 from moving to the fourth working position.

[0044] When the filter assembly 300 is removed from the cyclone drum 120, the second misassembly prevention member 150 is switched from the third working position to the fourth working position. Specifically, after the filter assembly 300 is removed from the cyclone drum 120, the pressing member 310 ceases to generate pressing force against the second misassembly prevention member 150, and the second misassembly prevention member 150 moves to the fourth working position.

[0045] Referring to Figure 5, in some embodiments, a groove 123 is provided at the end of the inner wall of the cyclone drum 120 near the top surface of the cyclone drum 120, and the groove 123 is used to accommodate the second misassembly prevention member 150. The second misassembly prevention member includes a column 151 that extends in the axial direction B of the cyclone drum 120, and the top surface of the column 151 is further away from the bottom of the groove 123 than the top surface of the cyclone drum 120.

[0046] Referring to Figure 9, in some embodiments, an engagement groove 210 is provided on the top surface of the dust collection body 200 facing the dust collection bucket 100, the second misassembly prevention member 150 is in a third working position, and when the dust collection body 200 is assembled to the dust collection bucket body 110, the column 151 is flush with the engagement groove 210, and at least a portion of the column 151 is inserted into the engagement groove 210. In some embodiments, the second misassembly prevention member 150 is in a fourth working position, the column 151 is not flush with the engagement groove 210, and the dust collection body 200 cannot be accurately assembled to the dust collection bucket body 110.

[0047] Referring to Figures 5 and 8, the second misassembly prevention member 150 pivots along the second rotation axis 152 in a plane perpendicular to the axis B of the cyclone drum 120. When the second misassembly prevention member 150 is in the third working position, the free end 153 of the second misassembly prevention member 150 is housed in the groove 123 in a plane perpendicular to the axis B of the cyclone drum 120. When the second misassembly prevention member 150 is in the fourth working position, the free end 153 of the second misassembly prevention member 150 moves away from the groove 123 in a plane perpendicular to the axis B of the cyclone drum 120.

[0048] In the embodiments of this disclosure, the cyclone drum is provided with a second misassembly prevention member, a filter assembly that cooperates with the second misassembly prevention member, and an engagement groove on the dust collection body. As a result, the dust collection body is assembled into the dust collection bucket only when the filter assembly is correctly attached to the dust collection bucket to which the cyclone drum is attached. This prevents dust and other particles from entering the dust collection body if the user forgets to attach the filter assembly, thus avoiding any malfunction of the vacuum cleaner. In this disclosure, by providing a mechanical misassembly prevention member on the dust collection bucket, a control circuit is not required, reducing costs and improving reliability.

[0049] Finally, note that each embodiment in this specification is described incrementally, each embodiment focuses on the differences from other embodiments, and identical or similar parts between embodiments may be referenced to one another. Systems or apparatus disclosed in embodiments are described briefly because they correspond to the methods disclosed in embodiments, but relevant parts should be referred to in the description of the methods section.
