[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The dust cup assembly 10 according to the first embodiment of the present invention is described below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 7 As shown, the dust cup assembly 10 according to the embodiment of the present invention includes: a cup body 100, a bottom cover 200, a cyclone separator 300, a guide member 400, a dust collecting cylinder 500 and a plurality of mesh covers 600. Here, a plurality includes two and more than two.

[0033] Specifically, the cup body 100 has a cleaning port 101. The bottom cover 200 is disposed on the cup body 100, and the bottom cover 200 can open and close the cleaning port 101. For example, the opening of the cleaning port 101 is downward, and the bottom cover 200 is rotatably disposed at the bottom of the cup body 100. The cyclone separator 300 is disposed in the cup body 100, and the guide member 400 is installed on the cyclone separator 300. For example, the guide member 400 can be a bolt structure and installed on the bottom wall of the cyclone separator 300, and the guide member 400 can be a metal member or a plastic member. The dust barrel 500 is movably mounted on the guide member 400 between a first position and a second position, and the cyclone separator 300 is connected to the dust barrel 500. For example, the dust barrel 500 is movable in the up and down directions. A plurality of mesh covers 600 are disposed in the cup body 100, and the plurality of mesh covers 600 are arranged around the cyclone separator 300, so that the plurality of mesh covers 600 can achieve coarse ash separation. For example, the mesh cover 600 is in an arc shape protruding outwards, and a stainless steel mesh or a nylon piece may be provided on the mesh cover 600 .

[0034] When the bottom cover 200 closes the cleaning port 101, the dust collecting barrel 500 is located in the first position, the dust collecting barrel 500 is supported by the bottom cover 200, and the multiple mesh covers 600 are supported by the dust collecting barrel 500. In this way, during operation, the dust gas passes through the coarse ash separation of the multiple mesh covers 600, and then enters the cyclone separator 300 for further dust gas separation, and the separated dust is collected in the dust collecting barrel 500 and the cup body 100. When the bottom cover 200 opens the cleaning port 101, the dust collecting barrel 500 is located in the second position, the dust collecting barrel 500 extends out of the cleaning port 101, the dust collecting barrel 500 is separated from the multiple mesh covers 600, and the bottom ends of the multiple mesh covers 600 are close to each other, so that the entangled objects on the outer surface of the mesh covers 600 and the dust in the cup body 100 and the dust collecting barrel 500 can be cleaned.

[0035] That is to say, the bottom cover 200 acts as a switch for the movement of the dust collecting bin 500. When the bottom cover 200 closes the cleaning port 101, it limits the position of the dust collecting bin 500. When the bottom cover 200 opens the cleaning port 101, it allows the dust collecting bin 500 to move downward, and the driving force for the dust collecting bin 500 to move downward is provided by multiple mesh covers 600.

[0036] According to the dust cup assembly 10 of the embodiment of the present invention, when cleaning is needed, the bottom cover 200 can be opened, and the bottom ends of the multiple mesh covers 600 can be retracted. At this time, the flocs such as hair wrapped on the mesh covers 600 will naturally fall off, and the multiple mesh covers 600 can push the dust collecting barrel 500 downward while moving toward each other, so that it can slide a certain distance (for example, it can extend downward 20 mm) to facilitate cleaning; when cleaning is completed, the dust collecting barrel 500 can be pushed up and the bottom cover 200 can be closed.

[0037] According to some embodiments of the present invention, Figure 1 , Figure 3 and Figure 6 As shown, the mesh cover 600 is rotatably arranged on the cyclone separator 300, so that the mesh covers 600 can be folded together by turning the mesh covers 600 inwards, and the structure is relatively simple. For example, the mesh cover 600 can be turned inwards by 5° to reduce the damage to the appearance of the mesh cover 600. It can be understood that the "inside" side refers to the side facing the inside of the cyclone separator 300.

[0038] According to some embodiments of the present invention, Figure 1 As shown, two adjacent mesh covers 600 are rotatably connected, and an elastic member 11 is provided between the two adjacent mesh covers 600 for making the bottom ends of the two adjacent mesh covers 600 move toward each other, so that the movement and reset of multiple mesh covers 600 can be achieved with a simple structure. For example, a rotating shaft 601 is provided on one of the two adjacent mesh covers 600 and an axial hole 602 is provided on the other, a rotating groove 301 is provided on the cyclone separator 300, and the rotating shaft 601 passes through the axial hole 602 and fits in the rotating groove 301; the elastic member 11 can be a torsion spring, which is sleeved on the rotating shaft 601. When the bottom cover 200 opens the cleaning port 101, the multiple mesh covers 600 move toward each other under the action of the torsion spring, pushing the dust collecting cylinder 500 to move downward.

[0039] According to some embodiments of the present invention, Figure 7 As shown, a stop flange 401 is provided at the lower end of the guide member 400 , and the dust collecting barrel 500 stops on the stop flange 401 when in the second position, thereby limiting the position of the dust collecting barrel 500 .

[0040] According to some embodiments of the present invention, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the bottom end of the dust collecting barrel 500 is open, and the bottom end of the dust collecting barrel 500 is blocked when the bottom cover 200 closes the cleaning port 101, and the bottom end of the dust collecting barrel 500 is opened when the bottom cover 200 opens the cleaning port 101. In other words, when the bottom cover 200 closes the cleaning port 101, a dust accommodating space is defined between the bottom cover 200 and the dust collecting barrel 500, and when the bottom cover 200 opens the cleaning port 101, the accommodating space is opened.

[0041] According to some embodiments of the present invention, Figure 1 and Figure 3 As shown, the dust collecting cylinder 500 has a receiving chamber with an open upper portion, and the cyclone separator 300 is fitted in the receiving chamber, thereby facilitating dust and gas separation effects, and the structure is compact and easy to assemble.

[0042] According to some embodiments of the present invention, Figure 1 and Figure 4As shown, the outer peripheral wall of the dust collecting barrel 500 is provided with a supporting edge 501 extending along the circumference of the dust collecting barrel 500. When the bottom cover 200 closes the cleaning port 101, multiple mesh covers 600 are supported on the supporting edge 501, thereby ensuring structural reliability and sealing.

[0043] According to some embodiments of the present invention, Figure 1 As shown, the dust collecting barrel 500 is provided with a plurality of filter petals 502, and the filter petals 502 are provided with a plurality of filter holes. The plurality of filter petals 502 and the plurality of mesh covers 600 are alternately arranged along the circumference of the cyclone separator 300, that is, a filter petal 502 is provided between two adjacent mesh covers 600, and a mesh cover 600 is provided between two adjacent filter petals 502, thereby ensuring coarse ash separation over the entire circumference of the cyclone separator 300.

[0044] According to some embodiments of the present invention, Figure 1 and Figure 3 As shown, the dust cup assembly 10 also includes: a filter element 700, the filter element 700 is installed on the cup body 100, and the cyclone separator 300 is connected to the filter element 700, so that the gas coming out of the cyclone separator 300 can be further filtered and purified by the filter element 700 before being discharged, and the dust and gas separation effect is better.

[0045] The following describes the assembly process and cleaning process of the dust cup assembly 10 according to a specific embodiment of the present invention.

[0046] In this embodiment, after the two mesh covers 600 are fixed through the shaft hole 602 and the rotating shaft 601, the torsion spring is installed, and then the filter element 700 is put on the corresponding position of the cyclone separator 300 from top to bottom, and then the filter element 700 is put on from top to bottom, and the filter element 700 and the cyclone separator 300 are fixed by two screws, so that the filter element 700, the two mesh covers 600, the two torsion springs, and the cyclone separator 300 are fixed together; further, the dust collecting cylinder 500 is fixed on the cyclone separator 300 by the guide member 400. At this time, it is assumed that flocculents such as hair have been entangled on the outer surface of the mesh cover 600.

[0047] When the bottom cover 200 is opened, the two mesh covers 600 flip inward by 5° under the action of the torsion spring. At the same time, the dust collecting tube 500 moves downward by 20 mm along the guide member 400 under the action of the mesh covers 600. At this time, hair and other flocs are naturally separated from the outer surfaces of the two mesh covers 600 and float in the air, and naturally fall out of the cup body 100 under the action of gravity.
