Automatic cigarette extinguisher

Abstract

The invention relates to an automatic cigarette extinguisher. The automatic cigarette extinguisher comprises a rack; a first roller, a second roller and an ash removal assembly are arranged on the rack; and the first roller and the second roller can rotate oppositely. The outer wall face of the first roller and the outer wall face of the second roller are both concave-convex faces and each comprise annular grooves formed in the axial direction at intervals; an annular protrusion is formed between every two adjacent annular grooves; the annular grooves and the annular protrusions are staggeredso that the friction coefficient of the surfaces of the rollers can be increased, and the probability that a cigarette butt moves on the rollers in the axial direction and slides out of the space between the two rollers is reduced. The annular grooves in one roller correspond to the annular protrusions on the other roller in position so as to form a clamped and embedded structure, and it is guaranteed that the gap between any fitting faces of the two rollers can extinguish the cigarette butt. The ash removal assembly comprises a first scraper blade and a second scraper blade, cigarette ash canbe scraped off under the condition that much cigarette ash is accumulated on the two rollers, and the technical problems that the concave-convex faces on the surfaces of the rollers are filled and leveled up, and consequently the cigarette butts are easy to separate from the two rollers are solved.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to an automatic smoke extinguisher. Background technique [0002] Smoking affects people's health, especially second-hand smoke, which is extremely harmful to the human body.
