Device for preventing dust in sweeper dust collection box from falling

Abstract

The embodiment of the invention discloses a device for preventing dust in a swepper dust collection box from falling off. The device comprises a storage box chamber arranged in a sweeper body, and a dust collection box is connected in the box storage chamber; an air rolling cylinder which is connected with the sweeper body and is used for rolling dust into the storage box chamber is arranged on the right side of the storage box chamber; an air suction opening is formed in the position, corresponding to the air rolling cylinder, of the side wall of the box storage chamber; a dust blocking structure is mounted in the air suction opening; the device can seal and block the air suction opening through an overhead door arranged at the position of the air suction opening to prevent dust at the dust collection box from falling off for the second time; during specific implementation, torsional springs on the two sides of the overhead door can push the overhead door all the time, so that it is guaranteed that the overhead door has enough force to enable a dust suction opening to be closed tightly, and even if the sweeper vibrates greatly, dust in the sweeper cannot leak out of the dust suction opening easily due to blocking of the overhead door.

Description

technical field [0001] The embodiment of the present invention relates to the field of sweeping machines, in particular to a device for preventing dust from falling from a dust suction box of the sweeping machine. Background technique [0002] Sweeping robot, also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning. Generally speaking, robots that complete cleaning, vacuuming, and mopping the floor are also collectively classified as sweeping robots. There are many structures in sweeping robots, and one of the more important structures is the dust collection box. [0003] At present, the dust collection box of the sweeper...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a device for preventing the dust from falling from the dust collection box of the sweeper to solve the problem in the prior art that some sweeping robots do not have any cover at the dust suction port, while some are inside the dust collection box. Add a barrier piece, when the user pulls out the dust box, the suction port can be closed by the gravity of the barrier piece, so that the dust will not easily fall from the dust collection box. It cannot completely close the dust suction port. If the sweeper produces some vibrations, the dust in the dust suction box is prone to secondary falling.
