DETAILED DESCRIPTION

[0024] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0025] The utility model discloses a dust collecting device for a vacuum cleaner. Figure 1 and Figure 2 As shown, it includes a barrel body 100 and a cyclone separation mechanism 200 installed in the barrel body 100, wherein an air inlet chamber A is formed between the inner wall of the barrel body 100 and the outer wall of the cyclone separation mechanism 200, and an air inlet 111 connected to the air inlet chamber A is opened on the barrel body 100; the cyclone separation mechanism 200 includes an upper mechanism portion 210, a lower mechanism portion 220, and a connecting portion 230 connected between the upper mechanism portion 210 and the lower mechanism portion 220; the upper mechanism portion 210 has an outer edge surface 211 for sealingly cooperating with the inner wall of the barrel body 100 so that an air outlet chamber B is formed between the upper mechanism portion 210 and the upper part of the barrel body 100, and an air outlet 121 connected to the air outlet chamber B is arranged on the barrel body 100; a dust collecting chamber C is formed between the lower mechanism portion 220 and the lower part of the barrel body 100, and the dust collecting chamber C has a function of being connected to the air inlet chamber A and being able to effectively block foreign matter. The connecting portion 230 includes a plurality of cyclone cones 231 structures whose calibers gradually decrease from top to bottom and which connect the air outlet chamber B and the dust collecting chamber C. At least one cyclone cone 231 is provided with an air inlet channel 232 connected to the air inlet chamber A. There is at least one air inlet channel 232 on the cyclone cone 231. Preferably, a blocking structure for blocking the dust carried in the airflow flowing in from the air inlet channel 232 from entering the air outlet chamber B is provided at the upper port where the air outlet chamber B is connected to the cyclone cone 231. In this way, the airflow carrying foreign matter such as dust, hair, etc. enters the air inlet chamber A from the air inlet port 111, and then enters the cyclone cone 231 from the air inlet channel 232. Under the action of the cyclone cone 231, the dust is separated from the ordinary airflow, and the dust enters the dust collecting chamber C under the action of the cyclone cone 231. The ordinary airflow enters the air outlet chamber and is discharged from the air outlet 121, thereby effectively realizing the separation and collection of dust.

[0026] In the above solution, the cyclone separation mechanism 200 further includes a filter ring 240 arranged outside the connecting portion 230, and the filter ring 240 is used to preliminarily filter the airflow entering the cyclone cone 231 to filter out larger foreign objects such as hair and paper scraps.

[0027] In the above scheme, the extension axis of the air inlet channel 232 is arranged horizontally or inclined downward and is eccentrically arranged with respect to the central axis of the cyclone cone 231, so that the airflow entering the cyclone cone 231 through the air inlet channel 232 can better form a downward-flowing vortex; further preferably, the outer side wall of the air inlet channel 232 is arranged tangent to the cone wall of the cyclone cone 231.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, the barrel body 100 includes a barrel main body 110 with open ends, a top cover 120 arranged at the upper end of the barrel main body 110, and a bottom cover 130 arranged at the lower end of the barrel main body 110; wherein a plurality of screw-on blocks are circumferentially spaced on the outer wall of the upper end of the barrel main body 110, and a screw-on groove is correspondingly arranged on the inner wall of the top cover 120, and the top cover 120 cooperates with the screw-on blocks through the screw-on groove to be detachably rotatably connected to the upper end of the barrel main body 110; one side of the bottom cover 130 is hingedly connected to the lower end of the barrel main body 110 and at least one buckle connection structure is further arranged between the bottom cover 130 and the barrel main body 110, so that the bottom cover 130 can be flipped open and installed on the lower end of the barrel main body 110.

[0029] In the above scheme, if Figure 2As shown, the upper end of the upper part 210 of the mechanism has a resting ring for resting on the upper end of the barrel body 110, and the lower side structure corresponding to the resting ring is formed with an outer edge surface 211 that is sealed and connected to the inner wall of the barrel body 110. Preferably, a sealing ring is embedded on the outer edge surface 211, so that the upper part 210 of the mechanism and the top cover 120 cooperate to form an air outlet cavity B, and the top cover 120 is provided with an air outlet 121 that is connected to the air outlet cavity B; preferably, the air outlet cavity B is also provided with a filter component such as filter cotton to filter the dust entering the air outlet cavity B; further preferably, the inner wall of the top cover 120 is provided with a filter that is connected to the barrel body 110 when it is snap-connected. The upper end portion of 10 cooperates with the limiting ring structure that clamps and fixes the rest ring of the upper portion 210 of the mechanism; the lower portion 220 of the mechanism has a dust collecting barrel 223, and the dust collecting barrel preferably has a collecting structure with a gradually decreasing inner diameter. The end face of the lower port of the dust collecting barrel 223 is arranged in a gap with the upper surface of the bottom cover 130 in the covered state, so that the dust collecting barrel 223 and the bottom cover 130 cooperate to form a dust collecting chamber C, and at the same time, a raised retaining ring 131 is arranged around the outer periphery of the lower port of the dust collecting barrel 223 on the upper surface of the bottom cover 130 corresponding to the lower port of the dust collecting barrel 223, and the upper end face of the retaining ring 131 extends to above the end face of the lower port of the dust collecting barrel 223, so as to form an outlet gap that can effectively prevent foreign matter from escaping.

The air inlet cylinder 212 is a conical structure with a larger upper part and a smaller lower part, and the lower end of the air inlet cylinder 212 extends to the bottom of the air inlet channel 232. Such a setting can effectively limit the foreign matter that enters the cyclone cone 231 through the air inlet channel 232 from entering the air inlet chamber A through the air inlet cylinder 212, thereby further ensuring the separation effect of the airflow and foreign matter of the cyclone cone 231.

[0031] In this embodiment, a corresponding structure is provided on the top wall of the lower part 220 of the mechanism with a concave cavity 221 for inserting and engaging the lower port of the cyclone cone 231, and a through hole 222 connected to the lower port of the cyclone cone 231 is provided on the concave cavity 221, thereby effectively improving the coordination effect between the lower part 220 of the mechanism and the connecting part 230.
