DESCRIPTION OF THE EMBODIMENTS

Preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, so that the advantages and features of the present disclosure can be more readily understood by those skilled in the art, and the scope of protection of the present disclosure can be more clearly defined.

The present disclosure provides a vacuum cleaner base station 100. The vacuum cleaner base station 100 is adapted to be connected to a handheld vacuum cleaner 200. After the handheld vacuum cleaner 200 is connected to the vacuum cleaner base station 100, dust removal, recharging, etc. can be performed on the handheld vacuum cleaner 200.

With reference to FIG. 2, the handheld vacuum cleaner 200 generally includes a vacuum cleaner main machine 201, a floor brush 202, and a hard tube 203 connecting the vacuum cleaner main machine 201 to the floor brush 202. Two ends of the hard tube 203 are detachably connected to the vacuum cleaner main machine 201 and the floor brush 202 respectively. To be specific, the handheld vacuum cleaner 200 may be disassembled into three parts, and the hard tube 203 is a stretchable tube. The assembled handheld vacuum cleaner 200 may be integrally supported on the vacuum cleaner base station 100. In this case, the vacuum cleaner base station 100 may recharge a vacuum cleaner and remove dust from the vacuum cleaner after sensing the handheld vacuum cleaner 200 in addition to supporting the handheld vacuum cleaner 200.

With reference to FIG. 1 and FIG. 3, the vacuum cleaner base station 100 includes a housing 1, where the housing 1 is substantially shaped in square, the housing 1 may be directly supported on the ground, a butt joint portion 2 is arranged on the housing 1, and the butt joint portion 2 may be combined with the handheld vacuum cleaner 200. The butt joint portion 2 is of a rod-shaped structure detachably connected to the housing 1. A butt joint recess 1111 allowing partial insertion of the butt joint portion 2 is formed in an upper plate 111 of an upper portion of the housing 1. The butt joint portion 2 is inserted into the butt joint recess 1111 to be fixed to the housing 1, and is removable from the butt joint recess 1111. The butt joint portion 2 is provided with a wire and a butt joint probe. When the handheld vacuum cleaner 200 is placed on the butt joint portion 2, the butt joint probe is in butt joint with a recharging head of the handheld vacuum cleaner 200 to recharge the handheld vacuum cleaner 200, and the vacuum cleaner base station 100 is in an operation state in this case.

With reference to FIG. 5, the housing 1 includes a first chamber 1a and a second chamber 1b, where a dust collection motor 3 is arranged in the second chamber 1b, and the dust collection motor 3 is configured to suck gas from the first chamber 1a to generate a suction force for sucking dust from a dust bucket of the handheld vacuum cleaner main machine 201. A dust bag (not shown in the figure) is detachably connected in the first chamber 1a. The dust bag is provided with a dust containing space for collecting the dust sucked from the dust bucket by the dust collection motor 3. When the dust bag is not expanded, the first chamber 1a may also store the butt joint portion 2 and the disassembled handheld vacuum cleaner 200. To be specific, the butt joint portion 2, the detached hard tube 203, the vacuum cleaner main machine 201, and the floor brush 202 may be placed in the housing 1.

With reference to FIG. 4, in a case where an entire butt joint portion 2 and an entire handheld vacuum cleaner 200 are placed in the first chamber 1a, there are no more components outside the housing 1, the vacuum cleaner is shaped in cuboid in whole, and thus is convenient to package and transport, and the vacuum cleaner base station 100 is in an accommodated state. Compared with the vacuum cleaner base station 100 that only has the functions of recharging and collecting dust in the prior art, according to the present disclosure, the vacuum cleaner base station 100 takes the transportation demand of the vacuum cleaner into account, and rationally utilizes the first chamber 1a for placing the dust bag. Thus, a space of the first chamber 1a is expanded, a larger dust bag can be employed, more dust can be stored, and the frequency of replacing the dust bag can be reduced. Moreover, during transportation and accommodation, the butt joint portion 2 and the disassembled handheld vacuum cleaner 200 can be stored in the first chamber 1a, and thus the vacuum cleaner base station 100 also has the function of storage. In this case, during package of the vacuum cleaner, it is not required to use a plurality of boxes, and the entire vacuum cleaner is packaged through the vacuum cleaner base station 100, so that cost saving is achieved.

In consideration of the transportation cost, the housing 1 has a length in an up-down direction less than 440 mm, a width in a left-right direction less than 330 mm, and a thickness in a front-rear direction less than 190 mm. Illustratively, in the present disclosure, the length, the width, and the thickness of the housing 1 are 433 mm, 319 mm, and 180 mm respectively. In this case, the interior of the housing 1 can satisfy the storage demand. Moreover, the housing conforms to the transportation size requirements, and thus the transportation cost is reduced.

Certainly, in other embodiments, the appearance of the housing 1 may alternatively be in other shapes, such as a polygon and a cylinder, which will not be described in sequence herein.

The first chamber 1a may also accommodate some accessories. To be specific, some complimentary parts matching the vacuum cleaner, such as a dust bag in a folded state and a cleaning head may also be accommodated in the first chamber 1a. To be specific, after the entire vacuum cleaner is packaged, only one housing 1 is presented finally. In this case, the housing 1, as a package box, accommodates all the parts.

With reference to FIG. 4 and FIG. 5, the housing 1 includes a casing 11 and a front cover plate 12 detachably connected to the casing 11. A first opening communicating with the first chamber 1a is formed in a front side of the casing 11, and various components of the handheld vacuum cleaner 200, the butt joint portion 2, and the dust bag enter and exit the first chamber 1a through the first opening. The front cover plate 12 covers the first opening. After the front cover plate 12 is removed, various components of the handheld vacuum cleaner 200, the butt joint portion 2, and the dust bag are manually taken or placed.

A sealing ring is further arranged between the casing 11 and the front cover plate 12, and the sealing ring is arranged around the first opening. In a case where the front cover plate 12 is fixed to the casing 11, the sealing ring is pressed to take a role of sealing. Particularly, when the dust collection motor 3 sucks gas from the first chamber 1a, negative pressure is rapidly generated in the first chamber 1a by the sealing ring. Illustratively, the casing 11 is provided with a recess surrounding the first opening, and the sealing ring is partially embedded in the recess.

To rapidly assemble or disassemble the casing 11 to or from the front cover plate 12, with reference to FIG. 6, an insertion protrusion is arranged on one edge of the front cover plate 12, a slot 1121 corresponding to the insertion protrusion is formed in the casing 11, and at least one magnetic attraction assembly is arranged between the front cover plate 12 and the casing 11. Through the cooperation between the insertion protrusion and the slot 1121, the position of the front cover plate 12 relative to the casing 11 can be preliminarily determined, so that the front cover plate 12 is positioned at the position corresponding to the first opening. The front cover plate 12 is fixed to the casing 11 through the magnetic attraction assembly, and thus assembly and disassembly are convenient, and the operation is facilitated.

The magnetic attraction assemblies may include magnets magnetically attracted to each other for cooperation, or a ferromagnetic material and a magnet magnetically attracted to each other for cooperation, which is not specifically limited. Illustratively, the magnetic attraction assemblies include an iron sheet fixed to the casing 11 and a magnet fixed to a corresponding position of the front cover plate 12.

In an embodiment, the insertion protrusion is positioned at a bottom of the front cover plate 12, the slot 1121 is formed in a lower plate 112, and the magnetic attraction assembly is positioned at a top of the front cover plate 12. In this case, the front cover plate 12 is manually turned up and down to be disassembled, which better conforms to the operating habits of ordinary operators.

The casing 11 includes an upper plate 111, the lower plate 112, two side plates 113, and a rear plate 114. The slot 1121 is formed in the lower plate 112. The casing 11 defines and forms a cuboid cavity, where a partition assembly 13 is arranged in the cavity to partition the cavity into the first chamber 1a and the second chamber 1b.

With reference to FIG. 6, the second chamber 1b is smaller than the first chamber 1a, and the second chamber 1b is positioned at a bottom corner of the cavity. In this case, the first chamber 1a is roughly L-shaped, and a region, positioned exactly above the second chamber 1b, of the first chamber 1a has a smaller length in the up-down direction, so as to place the floor brush 202 and the butt joint portion 2 that are smaller in length. A region, positioned on one side of the second chamber 1b, of the first chamber 1a has a greater length in the up-down direction, so as to place the vacuum cleaner main machine 201 and the hard tube 203 that are greater in length. In the embodiment, the space required by the handheld vacuum cleaner 200 and the butt joint portion 2 is fully considered, and the position of the second chamber 1b is rationally arranged, so that the first chamber 1a other than the second chamber 1b in the cavity is more rational to satisfy the storage demand.

The partition assembly 13 includes a surrounding plate 131 fixedly connected to the lower plate 112, one side plate 113, and the rear plate 114. A top plate 132 is fixed to a top of the surrounding plate 131. A second opening communicating with the second chamber 1b is formed in the lower plate 112. One second chamber 1b with the opening in the lower portion is delimited by the surrounding plate 131, the top plate 132, the one side plate 113, and the rear plate 114. The dust collection motor 3 enters and exits the second chamber 1b through the second opening. In this case, the dust collection motor 3 is inspected through the second opening without opening the front cover plate 12.

A first through hole 1321 enabling communication between the first chamber 1a and the second chamber 1b is formed in the top plate 132, and an air inlet of the dust collection motor 3 is aligned with the first through hole 1321. A second through hole 1131 enabling communication between the second chamber 1b and an external space of the housing 1 is formed in the one side plate 113 or the rear plate 114, and an air outlet of the dust collection motor 3 is aligned with the second through hole 1131. When the dust collection motor 3 operates, gas in the first chamber 1a is sucked out through the first through hole 1321, and discharged to the external space through the second through hole 1131. Illustratively, the second through hole 1131 is formed in the one side plate 113. Generally, the front cover plate 12 is placed against a wall, and the second through hole 1131 is not blocked in this case.

In an embodiment, to prevent dust in the first chamber 1a from entering the second chamber 1b, filter cotton fixedly connected to the top plate 132 is arranged at the first through hole 1321. Gas can pass through the filter cotton, but dust cannot pass through the filter cotton. The filter cotton is detachably connected to the top plate 132 to facilitate replacement of the filter cotton. Illustratively, a location recess is formed in the top plate 132, and the filter cotton is inserted into the location recess.

A connecting wire is fixed to the first circuit board 4, a plug 41 is fixed to an end portion of the connection wire, and the connection wire may extend out of the housing 1 to be connected to a socket, so as to supply power to a dust collection base. A power supply portion is arranged at a bottom of the butt joint recess 1111, and connected to the first circuit board 4 through a cable fixed to the housing 1. When the butt joint portion 2 is inserted into the butt joint recess 1111, the power supply portion is connected to a lead in the butt joint portion 2, so as to supply power to the handheld vacuum cleaner 200 through the butt joint portion 2.

For ease of package, the connection wire and the plug 41 may also be accommodated in the second chamber 1b, and the housing 1 has a smooth appearance without any components protruding outside the housing 1.

In an embodiment, a fixed plate 5 extending in a horizontal direction is fixed in the second chamber 1b, the fixed plate 5 partitions the second chamber 1b into an upper chamber 11b and a lower chamber 12b, the first circuit board 4 and the dust collection motor 3 are positioned in the upper chamber 11b, and the connection wire may be accommodated in the lower chamber 12b, and connected to the first circuit board 4 through a connector passing through the fixed plate 5. The connector is L-shaped to ensure horizontal penetration of the connection wire, so as to protect the connection wire. In the embodiment, the second chamber 1b is partitioned to further facilitate operations. When in use, the connection wire is directly pulled from the lower chamber 12b without interfering with the first circuit board 4 and the dust collection motor 3.

A containing recess 51 configured to contain the plug 41 is formed upwards from a lower surface of the fixed plate 5, and the plug 41 is inserted into the containing recess 51, and can only be removed with an external force without falling off under the gravity. The wire is coiled in the lower chamber 12b to satisfy the package and transportation demand. When in use, the plug 41 is directly taken out from the containing recess 51, and then the wire is pulled.

In an embodiment, with reference to FIG. 7, an avoidance notch 1132 penetrating the side plate in a thickness direction is formed upwards from the lower surface of the side plate 113, and the wire may pass through the side plate 113 through the notch 1132. The notch 1132 is arranged to ensure that the wire is protected without being pressed by the housing 1 during use.
