[0043] The following further non - restrictive detailed description of the technical solution of the utility model is made in conjunction with the preferred embodiments and their accompanying drawings. In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0044] As Figures 1 - 5As shown in the figure, a dust collection assembly according to an embodiment of the present utility model includes a dust cup 1, a filter assembly 3, and a body 6. The dust cup 1 is disposed on the body 6, and the bottom of the dust cup 1 is openable to facilitate dust cleaning. The filter assembly 3 is disposed inside the dust cup 1. The dust cup 1 has an air inlet 10. A motor (not shown in the figure) is disposed inside the body 6. The motor is used to provide a suction force. The suction force drives the mixed gas on the surface to be cleaned to enter the interior of the dust cup 1 through the air inlet 10. The filter assembly 3 is used to separate solid dust and clean air. The filter assembly 3 is usually a cyclone separation or has a breathable hole structure.

[0045] As Figure 3 shown, a first cavity portion 100 and at least one second cavity portion 101 that communicate with each other are formed inside the dust cup 1. The first cavity portion 100 and the second cavity portion 101 are arranged along the transverse direction of the dust cup 1. In this embodiment, one first cavity portion 100 and one second cavity portion 101 that communicate with each other are formed inside the dust cup 1. The filter assembly 3 is located in the first cavity portion 100 to perform the separation process of the mixed gas. The second cavity portion 101 is used to separately store the solid dust separated from the mixed gas. Separately providing one second cavity portion 101 for storing ash has a larger ash storage volume compared to the traditional dust cup with an up-and-down structure. Since the first cavity portion 100 and the second cavity portion 101 are designed as a left-right distribution structure, during use, it is possible to prevent the dust at the bottom of the second cavity portion 101 from being re-entrained into the filter assembly 3, affecting the separation efficiency.

[0046] Specifically, the dust collection assembly further includes a communication hole 4. The communication hole 4 is used to communicate the first cavity portion 100 and the second cavity portion 101.

[0047] Specifically, a partition 2 is disposed inside the dust cup 1. The partition 2 divides the interior of the dust cup 1 into the first cavity portion 100 and at least one second cavity portion 101. In this embodiment, the communication hole 4 is formed at the top of the partition 2. The solid dust separated by the filter assembly 3 enters the second cavity portion 101 through the communication hole 4.

[0048] As Figure 4 shown, the filter assembly 3 includes a cyclone acceleration portion 30 and a filter net 31. Both the cyclone acceleration portion 30 and the filter net 31 are disposed in the first cavity portion 100. Among them, the air inlet 10 is correspondingly disposed in the height direction of the cyclone acceleration portion 30 to prevent the mixed gas entering from the air inlet 10 from directly entering the mesh holes (not shown in the figure) of the filter net 31. The cyclone acceleration portion 30 has no ventilation holes. Therefore, the mixed gas will rotate along its surface. Without the cyclone acceleration portion 30, the particles in the mixed gas entering from the air inlet 10 will directly block the mesh holes of the filter net 31 at the corresponding opening.

[0049] Further, a guiding portion 300 is integrally formed on the outer side of the cyclone acceleration portion 30. The guiding portion 300 is spiral, and one end of the guiding portion 300 is located at the position of the air inlet 10, and the other end abuts against the partition plate 2. The guiding portion 300 can further guide the mixed gas, so that the mixed gas spirally rises along the surface of the guiding portion 300, and guides the mixed gas to the surface of the filter net 31 for separation. The separated solid dust enters the second cavity portion 101 from the communication hole 4 at the top under the drag of the air flow.

[0050] In addition, the communication hole 4 is located above the filter net 31 in the height direction. Since the mixed gas reaches the surface of the filter net 31 in a spiral shape, setting the through hole 4 above the filter net 31 can avoid the communication hole 4 from destroying the spiral structure of the mixed gas, and further avoid interfering with the separation efficiency of the filter net 31 for the mixed gas.

[0051] The filter assembly 3 further includes a mounting portion 32. The mounting portion 32 is arranged on the side of the filter net 31 away from the cyclone acceleration portion 30, and a sealing ring 33 is sleeved outside the mounting portion 32. The sealing ring 33 is made of soft rubber and abuts against the inner wall of the dust cup 1 to achieve internal sealing of the cyclone cavity.

[0052] As Figures 5 - 7 shown, the dust cup 1 includes a cup body 11 and a bottom cover 12. One side of the bottom cover 12 is hinged to the cup body 11 through a bottom cover rotating shaft 16, and the other side is buckled to the cup body 11. The filter assembly 3 is received in the cup body 11. When the bottom cover 12 is buckled to the cup body 11, the bottom cover 12 abuts against the cyclone acceleration portion 30.

[0053] A notch 121 is provided on the other side of the bottom cover 12, and limiting blocks 130 are provided at both ends of the notch 121. In the Figure 6 shown front-back direction, the bottom cover rotating shaft 16 is located between the two limiting blocks 130, which can make the bottom cover 12 better sealed.

[0054] As Figure 2 shown, the dust collection assembly further includes at least one manual buckle assembly 5. The other side of the bottom cover 12 is buckled to the cup body 11 through the manual buckle assembly 5. By adding a one-key ash dumping function, it is convenient for the user to directly open the bottom cover 12 of the dust cup 1 to remove the dust in the dust cup 1. In this embodiment, a pair of manual buckle assemblies 5 are provided, and the pair of manual buckle assemblies 5 are symmetrically arranged on both sides of the air inlet 10, and the distance d between the pair of manual buckle assemblies 5 is 60 - 80 mm.

[0055] As Figures 8 - 9 shown, an upstream air inlet channel 14 is provided at the end of the machine body 6. The upstream air inlet channel 14 is docked with the air inlet 10, and a pair of manual buckle assemblies 5 are arranged on both sides of the upstream air inlet channel 14.

[0056] As Figure 9As shown, a baffle 15 is provided at the air inlet 10 of the dust cup 1. When the motor works, the baffle 15 moves clockwise to open the air inlet 10.

[0057] As Figure 2 shown, the manual lock assembly 5 is provided at the joint of the body 6 and the dust cup 1, and both the body 6 and the dust cup 1 are located outside the manual lock assembly 5, which can effectively prevent the user from accidentally triggering the manual lock assembly 5 when placing the dust collection assembly on the table.

[0058] As Figure 5 shown, the manual lock assembly 5 includes a button 50 and an elastic member 51. The button 50 is rotatably connected to the dust cup 1 through a rotating shaft 52. One end of the elastic member 51 abuts against one end of the button 50, and the other end abuts against the dust cup 1. The other end of the button 50 can be buckled with the bottom cover 12.

[0059] The button 50 includes a pressing portion 500 and a buckling portion 501. The pressing portion 500 and the buckling portion 501 are located on both sides of the rotating shaft 52. One end of the elastic member 51 abuts against the pressing portion 500, and the buckling portion 501 is buckled with a fastener 120 on the bottom cover 12.

[0060] The dust cup 1 has a groove portion 13. At least part of the button 50 is received in the groove portion 13, and a limiting block 130 is provided in the groove portion 13 for limiting the buckling portion 501.

[0061] As Figure 1 shown, a cleaning device includes the above-mentioned dust collection assembly, a connecting portion 7, a sewage tank assembly 8 and a floor brush assembly 9. One end of the sewage tank assembly 8 is connected to the floor brush assembly 9, and the other end is connected to the dust collection assembly through the connecting portion 7.

[0062] The connecting portion 7 is in an elongated shape, which is convenient for the user to hold with one hand and move the cleaning device.

[0063] A baffle 70 is formed at the position of the connecting portion 7 corresponding to the manual lock assembly 5 to prevent the user from accidentally opening the bottom cover 12 of the dust cup 1 when using the cleaning device, resulting in dust spilling on the ground.

[0064] As Figure 6 shown, the shape of the notch 121 on the dust cup 1 matches the outer surface of the end of the body 6, so that the structure of the cleaning device is more compact.

[0065] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
