Abstract

A lawn mower is provided. The lawn mower includes a gripping portion provided with a toothed structure having multiple tooth units. A first extension direction of each of the tooth units forms an included angle of 75° to 105° with a length direction of the gripping portion and is not perpendicular to a traveling direction; the tooth units are spaced apart along the length direction of the gripping portion, and projections of any two adjacent tooth units on a plane perpendicular to the length direction of the gripping portion at least partially overlap. There is a first spacing between any two adjacent tooth units along the gripping portion. A minimum gap between orthographic projections of any two adjacent tooth units on a plane perpendicular to the traveling direction forms a second spacing. A ratio of the first spacing to the second spacing is greater than 1 and less than 5.

Dependent claims

A lawn mower, capable of traveling along a traveling direction on a traveling surface and comprising a body, wherein

the body comprises a front-side portion and a rear-side portion along the traveling direction and is provided with a through-hole arranged at the rear-side portion of the body, and a gripping portion is formed between the through-hole and an edge of the rear-side portion of the body;
the gripping portion is a strip-shaped member, and a toothed structure comprising a plurality of tooth units is arranged on a side of the gripping portion facing towards the traveling surface;
a projection of each of the tooth units on the traveling surface is strip-shaped with a first extension direction, an included angle between the first extension direction and a length direction of the gripping portion is greater than or equal to 75° and less than or equal to 105°, and an included angle between the first extension direction and the traveling direction is unequal to 90°;
and the plurality of tooth units are spaced apart along the length direction of the gripping portion, and projections of any two adjacent ones of the tooth units on a plane perpendicular to the length direction of the gripping portion at least partially overlap;
and
there is a first spacing D1 between the any two adjacent ones of the tooth units along the length direction of the gripping portion, and a minimum gap between orthographic projections of the any two adjacent ones of the tooth units on a plane perpendicular to the traveling direction forms a second spacing D2, wherein a ratio of the first spacing D1 to the second spacing D2 is greater than 1 and less than 5.
