Description

Dust collection box and cleaning robot with garbage leakage prevention design

Technical Field

The utility model relates to a cleaning equipment technical field especially relates to a dust collection box and cleaning machines people of rubbish leak protection design.

Background

Present intelligent machine of sweeping floor in market, its dust collection box inner structure often has the defect: when a user moves the sweeper after cleaning, the dust collection box can contain some dust, and the dust and other garbage can be scattered from the air suction opening due to the fact that the dust inlet of the side cover of the dust collection box is open; this not only causes repeated cleaning, reduces cleaning efficiency, but also greatly affects user experience; meanwhile, the defects are avoided by fixing the blocking piece of the partial dust collection box by screws in the market, but the manual work and the material are greatly wasted.

Chinese utility model patent 200710059909.4 discloses an inlet cover is equipped with before the air inlet, can prevent that the dust collection box from taking out the dust collection box that the in-process dust spills and falls, the inlet cover of dust collection box is connected with the guide arm, is equipped with the guide rail groove on the strengthening rib of the air inlet both sides of dust collection box, and the guide arm both ends insert the guide rail inslot respectively, and the guide arm both ends contact with the spacing muscle of dust catcher bottom shell both sides. When the dust collection box is placed into a bottom shell of the dust collector, two ends of the guide rod gradually descend along with the dust collection box and are jacked up along the guide rail groove by the limiting ribs on two sides of the bottom shell until the dust collection box falls into the bottom, the guide rod rises to the upper end of the guide rail groove, and the air inlet cover also rises to open the air inlet; on the contrary, when the dust collection box is taken out from the bottom shell of the dust collector, the air inlet cover can gradually generate relative descending displacement with the dust collection box along the guide rail groove under the action of gravity of the air inlet cover, so that when the two ends of the guide rod of the air inlet cover are separated from the limiting ribs of the bottom shell, the air inlet is sealed by the air inlet cover, and dust at the air inlet is prevented from scattering along with the vertical lifting of the dust collection box.

However, the dust-proof leakage-proof structure of the dust collection box disclosed in the chinese utility model 200710059909.4 can not automatically seal the air inlet of the dust collection box after the dust collection work is finished, but need control the guide arm upwards slide on the guide rail groove under the effect of human power, when the guide arm both ends of air inlet cover and the spacing muscle of drain pan break away from the contact, the air inlet can only be sealed to the air inlet cover, the sliding structure in this structure and the various spacing muscle of complex or the strengthening rib increase the structural complexity of dust collection box, and need to combine external force to act on the dust collection box and just can realize that rubbish is prevented spilling and leaking, and the air inlet can also inhale great granule rubbish thing, thereby block up the relevant passageway of the inside dust collecting chamber of dust collection box, influence clean effect, reduce user experience degree.

SUMMERY OF THE UTILITY MODEL

The utility model discloses optimize the prior art defect, designed one kind and established the dust collection box baffle on the peripheral tiny vertical bone position of dust inlet of dust collection box side cap to can inject the scope of dust collection box baffle luffing motion effectively by the horizontal bone position of dust collection box side cap, not only can guarantee that the dust catcher can freely inhale by the dust of normal during operation, guarantee when closing simultaneously that rubbish can not spill.

The technical scheme specifically comprises the following steps: a dust collection box with a garbage leakage-proof design comprises a dust collection box side cover and a box body, wherein the dust collection box side cover comprises a side shell, a top shell and a bottom shell, a dust collection chamber is arranged in the box body, the top shell, the bottom shell and the side shell are connected in a closed mode, the bottom shell of the dust collection box side cover is provided with a dust inlet communicated with the dust collection chamber, the inner surface of the top shell is provided with a group of horizontal bone positions crossing the front end and the rear end of the top shell, and the bottom shell is provided with a group of vertical bone positions which are adjacent to the horizontal bone positions and are vertical to; the dust collection box also comprises a dust collection box baffle plate which is inserted on the vertical bone position, and the surface of the dust collection box baffle plate is arranged below the horizontal bone position.
