Dust falling prevention mechanism for dust collection box of sweeper

Abstract

The embodiment of the invention discloses a dust falling prevention mechanism for a dust collection box of a sweeper. The mechanism comprises a dust box movably connected into a sweeper body and an air rolling cylinder installed in the sweeper body. A dust inlet is formed in one end, close to the air rolling cylinder, of the dust box; a blocking mechanism used for sealing the dust inlet is installed at the position, corresponding to the dust inlet, of the inner wall of the dust box. The air rolling cylidner is provided with a gear box. The cross section of the gearbox box is of a right trapezoid structure, and the gearbox box is used for pushing away the blocking mechanism and being inserted into the dust inlet to guide dust into the dust box; according to the invention, the blocking mechanism with an automatic closing effect is additionally arranged in the dust box; therefore, the problem of secondary falling of dust caused by untight sealing when the dust collection box is pulled outis solved, that is, when the dust collection box is not used in daily life or the sweeper is pulled out, the upper and lower blocking pieces can be pushed by the spring to block the dust collection port, and the upper and lower blocking pieces are not easily influenced even if the dust collection box is vibrated or shaken, so that dust in the box falls out.

Description

technical field [0001] The embodiment of the present invention relates to the field of sweeping machines, in particular to a mechanism for preventing dust from falling out of a dust collection box of the sweeping machine. Background technique [0002] The sweeper refers to the sweeping robot. In the near future, like white goods, it will become an indispensable cleaning helper for every family. Products will also develop from primary intelligence to a higher degree of intelligence, gradually replacing manual cleaning. It has many structures, one of the more important structures is the dust collection box. [0003] There are two forms of the suction port of the dust collection box today, one without any cover, and two, a barrier sheet is added inside the dust box, and the suction port is closed by the gravity of the barrier sheet when the dust box is pulled out. [0004] However, the common dust collection box is generally faced with a relatively simple structure. When the...

Problems solved by technology

[0004] However, the common dust collection box is generally faced with a relatively simple structure. When the dust collection box is pulled out, because the blocking structure at the suction port is such as a barrier plate that seals the suction port by gravity, its weight is relatively light. Large vibration or shaking of the dust box can make the barrier move up and down. At this time, once the dust collection box is pulled out, the dust or waste accumulated at the suction port will easily fall off, thus causing secondary pollution.
