Abstract
The present disclosure provides a grass collection mechanism, a grass collection device, and a lawn mower. The grass collection mechanism includes a grass collection frame and a conductive detection sensor. The conductive detection sensor is configured to detect whether the grass collection frame is full and includes at least one detection unit and a processing unit. The at least one detection unit is arranged on top of the grass collection frame and configured to be electrically connected to cut grass. The processing unit is electrically connected to the detection unit and configured to determine whether the detection unit is electrically conductive with the cut grass.
Claims18
A grass collection mechanism, comprising:
- a grass collection frame;
- and
- a conductive detection sensor configured to detect whether the grass collection frame is full and comprising at least one detection unit and a processing unit,
- wherein:
- the at least one detection unit is arranged on top of the grass collection frame and configured to be electrically connected to cut grass, the at least one detection unit being in a form of a conductive pillar comprising carbon fiber or metal;
- and
- the processing unit is electrically connected to the at least one detection unit and configured to determine whether the at least one detection unit is electrically connected with the cut grass.
A grass collection device, comprising:
- a grass collection frame comprising a front frame body configured to be detachably connected to a lawn mower body and a rear frame body configured to be rotatably connected to the front frame body;
- and
- a grass collection bag comprising a front bag portion and a rear bag portion,
- wherein:
- the front bag portion is adapted to the front frame body, the rear bag portion is adapted to the rear frame body, and the front bag portion and the rear bag portion are configured to be connected to each other in an openable manner;
- a grass-full detection unit is arranged within the front frame body, and a plurality of connecting columns corresponding to the grass-full detection unit are arranged within the rear frame body;
- and
- the connecting columns are staggered within the rear frame body, and the grass-full detection unit is configured to detect whether the connecting columns are covered by cut grass.
A grass collection device, comprising:
- a grass collection frame and a drive mechanism, wherein:
- a front side of the grass collection frame is configured to connect to a lawn mower body;
- the grass collection frame comprises a front frame body, a left frame body, and a right frame body, the front frame body being connected to the lawn mower body, the left frame body and the right frame body being respectively arranged on left and right sides of a rear portion of the front frame body;
- and
- the drive mechanism is connected to the grass collection frame to drive a first portion of the left frame body and a first portion of the right frame body to separate from each other to create a grass discharge opening of the grass collection device facing downward.
