Controllable opening structure for bottom cover of dust collection barrel

Abstract

The invention discloses a controllable opening structure for a bottom cover of a dust collection barrel, which comprises a bottom cover linkage arranged between a handle and a bottom cover and controlled by an operating rod. The bottom cover linkage comprises an L-shaped connecting rod, the bottom end of the operating rod is connected with the top end of the L-shaped connecting rod rigidly, and the rigid joint and a hinge shaft fixed with the handle of the dust collection barrel form a fulcrum. The operating rod is a swing rod moving around the fulcrum, a first vertical rod is hinged to a middle inflection point of the L-shaped connecting rod, a toothed cam is arranged at the other end of the L-shaped connecting rod and meshes with a gear, and the gear is arranged at the top end of the second vertical rod. The bottom end of the first vertical rod is inserted into the clamp block arranged at the edge of the bottom cover, a tension spring is arranged between one end of a clamping slot and a second vertical rod, a lock rod is fixedly connected to the other end of the clamping slot, and the other end of the lock rod is jointed to the edge of the bottom cover of the dust collection barrel through a fastener structure. After the controllable opening structure is applied to the dust collection barrel, a user can open the bottom cover of the dust collection barrel by a single hand. Further, opening degree of the bottom cover can be controllable, and dust flying can be avoided.

Description

technical field [0001] The invention relates to a structure of a dust collecting barrel of a vacuum cleaner, in particular to a lower opening structure of the dust collecting barrel of a vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum ...
