Abstract

A device for automatically detruding a cigarette butt includes a cigarette clamp, a cigarette fixer, a support ring, a cigarette butt detruding sliding ring, an air outlet end housing, a metal gasket, and a spring. After the cigarette is burnt and smoked, the cigarette butts can be detruded without the necessity of contacting the cigarette butts by hands in a low-resistance state.

Claims

1. A device for automatically detruding a cigarette butt, comprising:

a cigarette clamp, wherein an overall structure of the cigarette clamp is cylindrical in shape with two open ends;

a plurality of positioning protrusion blocks are provided on a cylinder wall of the cigarette clamp;

at least two cigarette clamping sheet bases are provided on the cylinder wall of the cigarette clamp;

each of the cigarette clamping sheet bases is an inter-slot cylinder wall formed by opening two U-shaped slots in an axial direction from an end portion of the cylinder wall;

a cigarette clamping sheet extending in an inward radial direction is provided on an end portion of each of the cigarette clamping sheet bases;

an elastic sheet extending in the axial direction is provided on the cigarette clamping sheet;

a space is disposed in the inward radial direction on the elastic sheet to expose the end portion of the cylinder wall on the cigarette clamping sheet bases;

a cigarette fixer, wherein an overall structure of the cigarette fixer is cup-shaped;

an inner diameter of the cigarette fixer gradually increases from a bottom of the cigarette fixer to a top of the cigarette fixer;

a circular connection hole and an arc-shaped airflow channel are provided on the bottom of the cigarette fixer, wherein a plurality of positioning arc-shaped convex points are arranged on an inner peripheral wall of the circular connection hole;

at least two first sliding grooves penetrating through a wall of the cigarette fixer are provided in the wall of the cigarette fixer;

a trapezoid platform with a sloped surface extending towards the bottom of the cigarette fixer is provided on an opening end of each first sliding groove;

a support ring, wherein an overall structure of the support ring is cylindrical in shape having two open ends;

a groove is provided on an inner wall of a first end of the support ring;

a flange is provided on an outer wall of a second end of the support ring;

at least two second sliding grooves penetrating through a cylinder wall of the support ring are provided in the cylinder wall of the support ring;

a cigarette butt detruding sliding ring, wherein an overall structure of the cigarette butt detruding sliding ring is cylindrical in shape having two open ends, and an annular groove and a positioning groove are provided on an inner wall of first end of the cigarette butt detruding sliding ring;

a shape of the positioning groove is matched with a shape of each positioning protrusion block on the cigarette clamp;

an air outlet end housing, wherein an overall structure of the air outlet end housing is in a hollow duckbill-shaped cylinder-like shape;

a first boss is provided on an end surface of one end of the air outlet end housing;

an arc-shaped airflow through hole and a second boss are provided on an end surface of the first boss;

a plurality of positioning arc-shaped concave points are provided on a peripheral wall of the second boss;

a number and a shape of the positioning arc-shaped concave points are matched with a number and a shape of the positioning arc-shaped convex points on the cigarette fixer

a metal gasket, wherein an overall structure of the metal gasket is a notched annular elastic member; and

a spring;

wherein,

the circular connection hole in the bottom of the cigarette fixer is sleeved on the second boss of the air outlet end housing, the circular connection hole and the second boss are connected to each other through a cooperation of the positioning arc-shaped convex point with the positioning arc-shaped concave point, the arc-shaped airflow channel and the arc-shaped airflow through hole butt each other after realizing a connection between the circular connection hole and the second boss;

the support ring is sleeved on an outer periphery of the cigarette fixer, the second sliding groove coincides with the first sliding groove, the groove of the support ring is sleeved on an outer periphery of the first boss of the air outlet end housing;

the cigarette clamp is sleeved on an outer periphery of the support ring, the cigarette clamping sheet base, the cigarette clamping sheet and the elastic sheet are located inside the second sliding groove and the first sliding groove, the elastic sheet and the trapezoid platform with the sloped surface of the cigarette fixer are in a straight direction;

the cigarette butt detruding sliding ring is sleeved on an outer periphery of the metal gasket and an outer periphery the flange of the support ring, the annular groove of a first end of the cigarette butt detruding sliding ring is connected to the metal gasket through clamping and sleeving the annular groove of the inner wall of the first end of the cigarette butt detruding sliding ring on the outer periphery of the metal gasket in a pre-stressed state, the cigarette butt detruding sliding ring is connected to the flange of the support ring through sleeving an inner wall of a second end of the cigarette butt detruding sliding ring on the outer periphery of the flange of the support ring, the positioning groove is matched with each positioning protrusion block; and

the spring is sleeved on an outer periphery of a cylindrical section of the support ring, ene a first end of the spring abuts against the end portion of the cylinder wall of the cigarette clamp and is sleeved on an outer periphery of the elastic sheet, a second end of the spring abuts against the flange of the support ring.

2. The device for automatically detruding the cigarette butt according to claim 1, wherein the metal gasket contacts the end portion on the cylinder wall of the cigarette clamp away from the elastic sheet in the axial direction.

3. The device for automatically detruding the cigarette butt according to claim 1, wherein an outer diameter of the cigarette fixer is constant, while a wall thickness of the cigarette fixer gradually decreases from a bottom end of the cigarette fixer to a top end of the cigarette fixer, thereby achieving an increase of the inner diameter of the cigarette fixer from the bottom end of the cigarette fixer to the top end of the cigarette fixer.

4. The device for automatically detruding the cigarette butt according to claim 1, wherein a side facet of the cigarette clamping sheet on the cigarette clamp is in contact with a side facet of the first sliding grooves on the cigarette fixer and a side facet of the second sliding grooves on the support ring when rotated, so as to transmit torque.

5. The device for automatically detruding the cigarette butt according to claim 1, wherein the cigarette clamp, the cigarette fixer and the support ring are made of an elastic material.
