They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0030] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example: Figure 1-10 As shown, the utility model discloses a first embodiment of a dust removal device, which includes: a cup body 200 having a cup body cavity 220, a cup cover 240 arranged above the cup body 200, a flow channel member 260 covering the upper end of the cup body cavity 220 and at least partially covered by the cup cover 240, a dust removal component 300 located in the cup body cavity 220, a cup cover handle 250 located on the cup cover 240 and rotatable relative to it, and a pair of locks 500 for fixing the cup cover 240 to the cup body 200.

[0032] The cup body 200 is generally cylindrical and made of injection-molded material, preferably a transparent or translucent plastic material to provide visibility of the interior of the cup body 200. The cup body 200 includes a cup body hole 224, an outer cup body groove 226, and a pair of cup body fixing posts 228 located above the cup body hole 224 and securing corresponding locking buckles 500. The cup lid 240 is also injection-molded material, allowing the input end of the flow channel component 260 to be at least partially exposed. The locking buckle 500 is rotatable relative to the cup body fixing posts 224.

[0033] The flow channel member 260 includes an exposed flow channel air inlet 262, a flow channel air outlet 263 connected to the flow channel air inlet 262 and tangentially discharging air relative to the cup body cavity 220, a flow channel input port 264 located in the center, and a flow channel output port 265 located on the outside. The flow channel air inlet 262 and the flow channel air outlet 263 form the input section of the flow channel member 260, while the flow channel input port 264 and the flow channel output port 265 form the output section of the flow channel member 260. The input section of the flow channel member 260 has a channel that is at least arc-shaped, while the output section of the flow channel member 260 has a channel that changes the direction of the airflow, preferably changing the direction of the airflow by 90 degrees. The airflow direction of the cup body hole 224 is different from the airflow direction of the flow channel air inlet 262, and more preferably, the two are opposite to each other.

[0034] The dust removal assembly 300 includes a filter frame 320 with multiple openings on its surface and a truncated cone shape, but with a hollow interior; a filter screen 340 disposed around the outside of the filter frame 320; and a float 360 located within the filter frame 320. The filter frame 320 has a larger upper end and a smaller lower end, and is removably mounted to the bottom of the flow channel member 260. The float 360 blocks the flow channel input port 264, thereby preventing further air from entering the flow channel air inlet 262.

[0035] The present invention further includes a garbage bag located in the cup cavity 220 and adhered to the inner wall of the cup 200 by a weak airflow, wherein the weak airflow enters from the cup hole 224. The garbage bag is made of a water-impermeable material, preferably a plastic bag.

[0036] Based on the first embodiment, Figure 1-10 As shown, the present invention discloses a second embodiment of a cleaning device, which includes a device body 100 capable of accommodating a cup body 200, a vacuum motor 400 located in the device body 100 and capable of forming a vacuum in the cup body cavity 220, a device cover 130 located above the device body 100, an air duct member 150 located between the device cover 130 and the vacuum motor 400, an air guide tube 144 having one end connected to the interior of the air duct member 150, and a device handle 160 located on the device cover 130 and rotatable relative to the device. The device body 100 is provided with a locking protrusion 114 on a side close to the cup body 200, which can be inserted into the cup body groove 226, and a main body hole 116 arranged adjacent to the locking protrusion 114 and correspondingly connected to the cup body hole 224, wherein the main body hole 116 is connected to the other end of the air guide tube 144.

[0037] The device body 100 is made of plastic material and is integrally injection-molded. It can be placed on a horizontal plane and includes a base 110 on one side and a step portion 120 on the other side. The locking protrusion 114 and the main body hole 116 are both located on the side of the base 110 close to the cup body 200. The vertical height of the base 110 is close to the vertical height of the cup body 200, while the vertical height of the step portion 120 is much smaller than the vertical height of the base 110. The step portion 120 is provided with a step receiving groove 122 for accommodating the bottom of the cup body 200. A motor chamber 140 for accommodating the vacuum motor 400 is formed in the base 110.

[0038] The air duct member 150 includes an air duct body 151, a hollow air guide tube 152 integrally formed on the air duct body 151, an air guide inlet 154 located at one end of the air guide tube 152, an air guide outlet 156 located at the other end of the air guide tube 152, and an inlet 158 ​​having one end connected to the interior of the air guide tube 152 and the other end connected to the air guide tube 144.

[0039] The vacuum motor 400 is preferably a brushless motor. This embodiment further includes an auxiliary filter located upstream of the vacuum motor 400 and downstream of the filter 340 , a control board electrically connected to the vacuum motor 400 , and a power unit for providing power to the vacuum motor 400 .

[0040] During operation, a stream of contaminated liquid enters the cup cavity 220 through the flow channel air inlet 262, where it undergoes a primary cyclone. Centrifugal force forces the liquid and large solid particles onto the inner wall of the cup 200. When the liquid level in the cup cavity 220 exceeds a certain level, the float 360 blocks the flow channel inlet 264, preventing the entry of contaminated liquid. The fine dust-laden air continues through the filter 340 and is further filtered by the auxiliary filter element upstream of the vacuum motor 400. The air then enters the vacuum motor 4000, where it rotates through the high-speed impeller. The clean air is ultimately discharged into the atmosphere through the air outlet of the base 110.

[0041] The utility model has the advantages that the cup body is provided with a cup body hole allowing air flow to pass through, so that the garbage bag is convenient to fix and the garbage bag can also be used as a garbage bin, thereby realizing the multifunctional use of the cleaning tool.

[0042] 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.
