Description

Outdoor ashtray

Technical Field

The invention relates to the field of articles for daily use, in particular to an outdoor ashtray.

Background

The ashtray is a common living article; the existing ashtray has no other purposes basically when being used for containing cigarette ash. In fact, smokers often lose or forget the lighter when smoking, and sometimes cannot find the lighter half a day when smoking is needed.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide an outdoor ashtray, which can not only hold cigarette ash, but also light cigarette, and has a simple structure and a low cost.

The technical scheme adopted by the invention for solving the technical problems is as follows: the outdoor ashtray comprises an ashtray body, wherein a lower concave cavity is formed in the upper portion of the ashtray body, the lower concave cavity is a parabolic mirror surface, and parallel light projected vertically downwards can be converged above the lower concave cavity after being reflected.

Preferably, a concave lining is further lined in the lower cavity, the concave lining can be placed into and taken out of the lower cavity, and cigarette ash is contained in the concave lining during smoking; not only can prevent the cigarette ash from shielding the parabolic mirror surface of the lower concave cavity, but also is convenient for cleaning the ashtray.

Preferably, 3-4 clamping grooves for holding cigarettes are uniformly distributed on the upper edge of the cylinder body in the circumferential direction, and the focus of the parabolic mirror is located at the intersection of the axes of the clamping grooves; therefore, the cigarette is horizontally placed in the clamping groove, and when the cigarette end is positioned at the center of the upper end opening of the ashtray body, the cigarette end can be ignited.

Preferably, the center of the bottom of the lower concave cavity is provided with a small hole, and the bottom of the cylinder body is formed by a horizontal bottom plate; the connecting line of the small hole and the center of the horizontal bottom plate is vertical to the horizontal bottom plate; the center of the horizontal bottom plate is provided with a mark; the side wall of the cylinder body is composed of transparent walls, so that a user can observe the upper surface of the horizontal bottom plate through the side wall of the cylinder body; thus, when the sun is obliquely emitted, the user can incline the cylinder body, so that the solar light spot passing through the small hole is superposed with the center of the horizontal bottom plate, and the sunlight is parallel to the axis of the parabolic mirror surface of the lower concave cavity; at the moment, the reflected light converging point of the parabolic mirror can be ensured to fall on the axis of the parabolic mirror, so that the cigarette end lighting position can be conveniently positioned.

Preferably, the cylinder body is also provided with a color-changing cover plate which can horizontally cover the lower concave cavity; the color-changing cover plate is composed of photochromic glass sheets; therefore, when the sun shines obliquely, the lower concave cavity is covered by the color-changing cover plate, the area, near the connecting line of the light convergence point and the center of the lower concave cavity, of the color-changing cover plate is extremely concentrated due to irradiated sunlight radiation, so that the color is obviously darker than other areas, and a local dark color area is formed, therefore, after the user opens the color-changing cover plate, the cigarette lighting position is searched on the connecting line of the center of the local dark color area and the center of the lower concave cavity (namely, the cigarette lighting position is enough at the obliquely upper position of the local dark color area and the temperature near the light convergence point, so the cigarette lighting position is not necessarily very accurate.)

The invention has the beneficial effects that: when the outdoor ashtray is used, outdoor sunlight is reflected by the lower concave cavity and converged above the lower concave cavity, so that a cigarette end can be ignited by only placing the cigarette end above the lower concave cavity; it is worth mentioning that even if the ashtray is not provided with a cover, when the common combustible is arranged above the ashtray, the common combustible can not be burnt because the sunlight is shielded by the combustible, and the ashtray is very safe.

Detailed Description

The first embodiment is as follows:

in the first embodiment shown in fig. 1, the outdoor ashtray comprises an ashtray body 1, wherein a lower concave cavity 10 is formed in the upper part of the ashtray body 1, and the lower concave cavity 10 is a parabolic mirror surface and can reflect parallel light projected vertically downwards and then converge above the lower concave cavity 10.

In addition, a concave lining (not shown) is lined in the lower cavity 10, and the concave lining can be put into and taken out of the lower cavity 10, and cigarette ash is contained in the concave lining during smoking; not only can the cigarette ash be prevented from shielding the parabolic mirror surface of the lower concave cavity 10, but also the ashtray can be cleaned conveniently.

3-4 clamping grooves 11 for placing cigarettes are uniformly distributed on the upper edge of the cylinder body 1 in the circumferential direction, and the focus of the parabolic mirror is located at the intersection of the axes of the clamping grooves 11, namely the center of the upper port of the cylinder body 1; therefore, the cigarette is horizontally placed in the clamping groove 11, and when the cigarette end is positioned at the center of the upper end opening of the ashtray body, the cigarette end can be ignited.

In the first embodiment, a small hole 100 is formed in the center of the bottom of the lower cavity 10, and the bottom of the cylinder body 1 is formed by a horizontal bottom plate 12; the line between the small hole 100 and the center of the horizontal bottom plate 12 is perpendicular to the horizontal bottom plate 12; the center of the horizontal bottom plate 12 is provided with a mark, such as a cross-shaped marked line; the side wall of the cylinder body 1 is formed by a transparent wall, so that a user can see the upper surface of the horizontal bottom plate 12 through the side wall of the cylinder body; thus, when the sun is obliquely projected, the user can tilt the cylinder 1 so that the solar spot passing through the small hole 100 coincides with the center of the horizontal bottom plate 12, and the sunlight is parallel to the axis of the parabolic mirror surface of the lower cavity 10; the reflected light converging point of the parabolic mirror can be ensured to fall on the axis of the parabolic mirror, so that the cigarette end lighting position can be conveniently positioned; in the first embodiment, when the ashtray body 1 is inclined, the cigarette can be kept clamped in the clamping groove 11, and when the solar facula is overlapped with the center of the horizontal bottom plate 12, the light converging point naturally falls on the cigarette end.

When the outdoor ashtray is used, outdoor sunlight is reflected by the lower concave cavity 10 and converged above the lower concave cavity 10, so that a cigarette end can be ignited as long as the cigarette end is placed above the lower concave cavity 10 by a user; it is worth mentioning that even if the ashtray is not provided with a cover, when the common combustible is arranged above the ashtray, the common combustible can not be burnt because the sunlight is shielded by the combustible, and the ashtray is very safe.

Example two:

for the second embodiment shown in fig. 2, the center of the concave cavity 10 of the cylinder 1 is not provided with a small hole; the cylinder body is also provided with a color-changing cover plate 2 which can horizontally cover the lower concave cavity 10; the color-changing cover plate 2 is composed of photochromic glass sheets; therefore, when the sun is obliquely projected, the color-changing cover plate 2 covers the lower concave cavity 10, the area of the color-changing cover plate 2 near the connecting line of the light convergence point and the center of the lower concave cavity 10 is extremely concentrated due to irradiated sunlight radiation, so that the color is obviously darker than other areas, and a local dark color area is formed, therefore, after the user opens the color-changing cover plate 2, the cigarette lighting position is searched on the connecting line of the center of the local dark color area and the center of the lower concave cavity 10 (namely, the cigarette lighting position is enough at the obliquely upper position of the local dark color area and the temperature near the light convergence point, so the cigarette lighting position is not required to be very accurate.)

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
