Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning, in particular to a dust cup and a wet and dry dual-purpose vacuum cleaner. Background Art

[0002] Vacuum cleaners typically come in two types: dry and wet. Dry vacuum cleaners collect dust, while wet vacuum cleaners collect water from the floor. These cleaners also have complex internal structures. To address the problem of traditional dry vacuum cleaners being unable to handle waterlogged floors, the industry has developed wet-dry vacuum cleaners. These separate the motor compartment from the dust collection chamber, preventing water from entering the motor compartment and causing a motor short circuit. However, existing wet-dry vacuum cleaners are prone to dirt accumulation once water accumulates in the dust cup. Over time, this dirt becomes increasingly difficult to clean, and the wastewater easily becomes smelly, causing significant discomfort to users. This requires improvement. Utility Model Content

[0026] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example: Figure 1-3 As shown, the present invention discloses a first embodiment of a dust cup, which includes: a dust cup body 100 having a dust cup cavity 120 and a dust cup through hole 124, and a cup cover 400 arranged above the cup body 100 and having a float bar 440.

[0028] The dust cup body 100 is in the shape of a hollow cylinder and is made of transparent plastic material so that the dust collection status of the dust cup cavity 120 can be understood. The dust cup through hole 124 is located on one side of the dust cup cavity 120.

[0029] The cup lid 400 includes an annular cup lid sidewall 401, a cup lid air inlet 403 located on the inner side of the cup lid sidewall 401, a cup lid air outlet 404 located in the center and surrounded by the cup lid sidewall 401, a float fence 440 connected to the cup lid air outlet 404, and a float 420 located within the float fence 440 and capable of shielding the cup lid air outlet 404. The cup lid air inlet 403 is tangentially oriented relative to the cup lid air outlet 404. The float fence 440 includes a plurality of circumferentially spaced fences and a filter screen having a plurality of meshes surrounding the outer sides of the fences, wherein the float 420 is located on the inner side of the filter screen, and a portion of the fences extends in the axial direction. The cross-sectional area of ​​the dust cup through hole 124 is smaller than the cross-sectional area of ​​the cup lid air inlet 403. The cup lid air inlet 403 is located between the cup lid sidewall 401 and the cup lid air outlet 404.

[0030] This embodiment further includes a flexible collecting member 500 located within the dust cup cavity 120 and having one end open for collecting solids or liquids, wherein the flexible collecting member 500 is at least partially unfolded by the airflow entering the dust cup through hole 124 and positioned on the inner wall of the dust cup body 100. The flexible collecting member 500 is a disposable, impermeable garbage bag, preferably a plastic bag.

[0031] Based on the first embodiment, Figure 4-7 As shown, the present invention discloses a second embodiment of a wet and dry vacuum cleaner, which includes: a dust cup, a vacuum cleaner shell 200 that at least partially accommodates the dust cup and has a shell cavity 220, and a vacuum motor 300 located in the shell cavity 220, wherein the dust cup is the dust cup in the first embodiment.

[0032] The vacuum cleaner shell 200 is roughly rectangular and can be placed on a horizontal plane. It includes a dust cup accommodating chamber 210 for at least partially accommodating a dust cup, an air outlet chamber 205 located above the cup cover 400, a handle 230 arranged adjacent to the air outlet chamber 205 and located at the top, an air inlet channel at least partially located in the air outlet chamber 205 and connected to the air inlet 202 at one end, a tangential air inlet 203 located at the other end of the air inlet channel, a through hole 206 connected to the cup cover air outlet 404 and connected to the air outlet chamber 205, an air outlet 209 located between the air outlet chamber 205 and the air duct conversion part 600 and downstream of the cup cover air outlet 404, an air inlet 202 connected to the dust cup chamber 120, an air flow hole 204 connected to the dust cup through hole 124, and an air duct conversion part 600 located in the shell cavity 220 and whose input is connected to the cup cover air outlet 404. The extending direction of the handle 230 is the same as the width direction of the cleaner housing 200 .

[0033] The vacuum motor 300 is a brushless DC motor, a brushed DC motor, or an AC series motor. The motor axis of the vacuum motor 300 is perpendicular to the horizontal plane, and the head of the vacuum motor 300 is located above the tail.

[0034] The air duct conversion unit 600 includes a conversion air inlet 602 at the input end, a conversion air outlet duct 207 selectively connected to the conversion air inlet 602, and a conversion air outlet 208 at the output end of the conversion air outlet duct 207. The other end of the conversion air inlet 602 can selectively connect to the head of the vacuum motor 300, thereby achieving air duct conversion, realizing the conversion between the dust collection duct and the blowing duct.

[0035] The flexible collecting member 500 is a disposable and impermeable garbage bag, preferably a plastic bag.

[0036] Before working, the vacuum motor 300 operates at a power lower than normal, and a vacuum is generated through the air flow holes 204, the dust cup through holes 124 and in the dust cup cavity 120, thereby unfolding the flexible collecting piece 500 and positioning it on the inner wall of the dust cup body 100, that is, opening the upper end of the garbage bag and making the surrounding side of the garbage bag contact the inner wall of the dust cup body 100 as much as possible, thereby preparing for the installation of the garbage bag; during operation, an air flow containing dirty liquid and solid enters from the air inlet 202, cyclones in the dust cup cavity 120, and the liquid and large particles of solid are thrown to the inner wall of the dust cup body 100 under the action of centrifugal force, and the air flow containing fine dust passes through the filter, then enters the cup cover air outlet 404, enters through the conversion air inlet 602, and then enters the vacuum motor 300, and is finally discharged to the outside. When the blowing function is needed, the air duct conversion part 600 is converted, and the user connects the blowing tube to the conversion outlet 208. The airflow discharged by the vacuum motor 300 is transferred into the air duct conversion part 600 and flows out of the conversion outlet 208 through the conversion outlet duct 207. When the work is finished, the dust cup is removed from the housing 200, and the cup cover 400 is unlocked from the dust cup body 100. The flexible collecting member 500 can be discarded by lifting the upper end of the flexible collecting member 500, thereby reducing the accumulation of water and dirt in the dust cup cavity 120 and reducing the generation of odor.

[0037] The utility model has the advantages of collecting sewage and garbage through a disposable flexible collecting piece, discarding it at a regular time, facilitating the cleaning of the interior of the dust cup and being reusable, reducing the residue of sewage and dirt, and reducing the generation of sewage odor.

[0038] The above are only preferred implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
