DETAILED DESCRIPTION

The embodiments of the present disclosure will be described in detail as follows. The examples of the embodiments are shown in the drawings. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.

Reference will be made to the drawings to describe the dust barrel assembly 1 for a vacuum cleaner according to the embodiments of the present invention.

As shown in FIGS. 1-4, the dust barrel assembly 1 for the vacuum cleaner according to the embodiments of the present invention includes a dust barrel 100, a mesh filter 200 and a cyclone cone 300.

The mesh filter 200 is installed in the dust barrel 100. One of the cyclone cone 300 and the mesh filter 200 is provided with a screw groove 210, and the other one is provided with a screw lug 310. The cyclone cone 300 is installed on the mesh filter 200 by the screw lug 310 screwed in the screw groove 210.

In the dust barrel assembly 1 for the vacuum cleaner according to the embodiments of the present invention, the screw lug 310 is disposed on one of the mesh filter 200 and the cyclone cone 300, and the screw lug 310 is disposed on the other one of the mesh filter 200 and the cyclone cone 300. Therefore, the cyclone cone 300 can be installed on the mesh filter 200 by the screw lug 310 screwed in the screw groove 210. Thus, the cyclone cone 300 can be installed on the mesh filter 200 only by screwing the screw lug 310 into the screw groove 210 during assembling. The procedure of installing bolts can be omitted, thereby leading to easy assembling, raising assembling efficiency and saving labor cost.

Furthermore, since no bolt is required for fixing the mesh filter 200 and the cyclone cone 300, the number of parts is reduced and the cost of the bolts is saved, which is beneficial for parts management and further reduces the cost of the dust barrel assembly 1 for the vacuum cleaner.

Therefore, the dust barrel assembly 1 for the vacuum cleaner shows advantages of easy assembling, low cost and so forth.

Reference will be made as follows to the drawings to describe the dust barrel assembly 1 for vacuum cleaner according to the embodiment of the present invention.

In some specific embodiments of the present invention, as shown in FIGS. 1-4, the dust barrel assembly 1 for the vacuum cleaner according to the embodiments of the present invention includes the dust barrel 100, the mesh filter 200 and the cyclone cone 300.

The screw groove 210 can be disposed on the outer peripheral surface of the mesh filter 200 and the screw lug 310 can be disposed on the inner peripheral surface of the cyclone cone 300. Thus, the screw lug 310 and the screw groove 210 are formed, and the screw lug 310 can be conveniently screwed into the screw groove 210.

Optionally, as shown in FIGS. 2-4, a plurality of screw grooves 210 may be arranged along in a circumferential direction of the mesh filter 200 at intervals. A plurality of screw lugs 310 may be arranged along in a circumferential direction of the cyclone cone 300 at intervals, and the plurality of screw lugs 310 may be screwed into the plurality of screw grooves 210 respectively. Thereby facilitating assembling of the cyclone cone 300 and the mesh filter 200, and improving the installing strength and the stability of the mesh filter 200 and the cyclone cone 300 by fitting between the plurality of screw grooves 210 and the plurality of screw lugs 310.

Advantageously, the plurality of screw lugs 310 can be arranged along in the circumferential direction of the cyclone cone 300 at equal intervals, and the plurality of screw grooves 210 can be arranged along in the circumferential direction of the mesh filter 200 at equal intervals. Thus more choices of a relative angel between the mesh filter 200 and the cyclone cone 300 during assembling is available, which further facilitates the assembling of the cyclone cone 300 and the mesh filter 200.

Specifically, as shown in FIG. 2 and FIG. 3, two screw grooves 210 may be provided opposite to each other in a radial direction of the mesh filter 200, and two screw lugs 310 may be provided opposite to each other in a radial direction of the cyclone cone 300. Thus, the manufacturing cost of the cyclone cone 300 and the mesh filter 200 is reduced on the premise that the assembling reliability is ensured.

The two screw lugs 310 may have cross sections with different diameters, the two screw grooves 210 may have different widths, and the widths of the two screw grooves 210 may match with the diameters of the cross section of the two screw lugs 310 respectively. Therefore, the cyclone cone 300 can be positioned to avoid dislocation when installed in the circumferential direction.

FIG. 4 shows the dust barrel assembly 1 for the vacuum cleaner according to a specific embodiment of the present invention. As shown in FIG. 4, each screw groove 210 may include an assembling section 211 and a limiting section 212. The assembling section 211 may extend along in a vertical direction and have an open lower end. The limiting section 212 may extend along in a horizontal direction and communicate with an upper end of the assembling section 211. The limiting sections 212 of the plurality of screw grooves 210 may extend from the assembling section 211 to the same direction along in the circumferential direction of the mesh filter 200. Thus the screw lug 310 can be easily screwed into the screw groove 210 and the screw lug 310 hardly separate from the screw groove 210, which improves the reliability of the dust barrel assembly 1 after assembling.

Advantageously, as shown in FIG. 4, the connection between the assembling section 211 and the limiting section 212 may have an arc transition and be provided with a stop protrusion 213 used for preventing each screw lug 310 from sliding into the assembling section 211 from the limiting section 212. Therefore, each screw lug 310 may easily slide into each screw groove 210, and the stop protrusion 213 can be used for limiting each screw lug 310 to prevent each screw lug 310 from sliding into the assembling section 211 from the limiting section 212, thereby further improving the reliability of the dust component 1 after assembling.

Alternatively, as shown in FIGS. 2 and 3, the connection between a bottom wall face and a side wall face of each screw groove 210 may have an arc transition. Each screw lug 310 may be in the shape of a cylinder, and an edge of an end surface of each screw lug 310 may have an arc transition. Thus, each screw lug 310 can more smoothly slide into each screw groove 210, which further facilitates the assembling of the dust barrel assembly 1.

Specifically, as shown in FIGS. 1, 2 and 4, the mesh filter 200 may be provided with an annular stop platform 220 to prevent the cyclone cone 300 from moving upward. Therefore, the cyclone cone 300 can be positioned by the annular stop platform 200, which makes it convenient to determine whether the cyclone cone 300 is installed in place during assembling, further facilitates the assembling of the dust barrel assembly 1, and improves the stability of the cyclone cone 300 after assembling.

A gap is provided between an outer peripheral surface of the cyclone cone 300 and an inner peripheral surface of the dust barrel 100. Thus, air can flow smoothly, which further facilitates assembling of the dust barrel assembly 1.
