[0002] A vacuum cleaner is a tool used to suck up dust from the surface of an object and clean it. Conventional vacuum cleaners are large in size and not convenient to use with one hand. Existing small vacuum cleaners need to be disassembled as a whole for cleaning the inside, and both hands are required to empty the dust, which makes emptying the dust inconvenient. Some small vacuum cleaners connect the dust cup and the barrel with a snap, which is easy to fall off, reducing the safety performance of the vacuum cleaner.

[0003] A Chinese patent document CN108209701A discloses a vacuum cleaner, the lower part of which includes a dust cup, the upper cover of the upper part contains a battery assembly and a motor assembly, and the dust cup is detachably connected to the upper cover. The air duct structure includes: an air inlet pipe, which is located at the bottom end of the lower part; an air inlet, which is located at the upper part of the side wall of the dust cup; an air guide pipe, which extends upward from the air inlet pipe along the outer wall of the dust cup to the air inlet; a filter assembly, which is detachably coaxially arranged in the dust cup, and the filter assembly is coaxially arranged below the suction motor; when the vacuum cleaner is cleaning, the dust cup needs to be detached from the body, which affects the user experience and time. Therefore, we provide a small columnar vacuum cleaner that is easy to empty, the upper cover can be flipped open, and the entire dust cup is detachable, which is convenient and lightweight, and improves the user's efficiency.
