Embodiment Construction
[0040] The present invention will be described in detail below with reference to the drawings and examples.
[0041] The components in the present invention that are the same as those in the prior art use the same symbols.
[0042] Such as Figure 2-Figure 7 As shown, the dust collecting barrel of the vacuum cleaner with the cyclone structure includes the barrel body 2 and the upper cover 1 with the air outlet 4 formed thereon and the bottom cover 3 connected by the hinge 19 below; Filter 5 upper mouth and the separating barrel 9a of filter periphery. The screwing rib 13 of the separating barrel 9a is connected to the outer ring spiral groove 14 on the bottom surface of the upper cover 1; One side of the barrel body 2 is provided with a handle 7 on which the barrel body fixing button 22 is installed, and an obliquely connected barrel air inlet pipe opening 8 is formed on the upper part of the side wall, and a bottom cover opening button 6 is provided at the bottom; a cylindr...

The invention discloses a dust collecting barrel of a vacuum cleaner with a whirlwind structure, pertaining to the cyclone of the vacuum cleaner or a device with a centrifugal effect; the dust collecting barrel comprises a barrel provided with an air inlet pipe opening, an upper cover provided with an air outlet and a bottom cover connected by hinges at the lower part thereof; wherein the bottom surface of the upper cover is rotatably connected with a filter communicated with the air outlet and a separating barrel arranged at the periphery of the filter respectively, the upper part of the separating barrel is provided with an internal air inlet pipe opening with the same direction of that of the air inlet pipe opening of the barrel at the position corresponding to the air inlet pipe opening of the barrel, an air rotating area without meshes is formed at the position of a tapering filter which is uniformly distributed with meshes corresponding to the internal air inlet pipe opening, and a spiral dust output structure is formed at the lower part of the separating barrel; therefore, the separated dust is not needed to be accumulated to a great amount to drop on the bottom cover, on the contrary, the separated dust constantly drops on the bottom cover along the spiral dust output structure formed at the lower part of the separating barrel and with the rotating air so as to be cleaned, thus improving the service performance of the vacuum cleaner.
Description
technical field [0001] The invention relates to a cyclone of a vacuum cleaner, or a device with a centrifugal effect, in particular to a dust collecting bucket of a vacuum cleaner with a cyclone structure which can better separate dust from air, prevent filters from being blocked, and improve the performance of the vacuum cleaner. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. According to the shape of the vacuum cleaner, it can be divided into vertical vacuum cleaners, horizontal (tank) vacuum cleaners and portable vacuum cleaners. [0003] When the vacuum cleaner is running, the motor drives the fan to rotate at high speed to expel the air inside the vacuum cleaner, forming an instantaneous vacuum inside the vacuum cleaner, and forming a relatively high negative pressure difference with the outside atmosphere.
