Technical realization elements:

The purpose is to provide a bubble tube lamp for decoration, which has a reasonable structure and can effectively prevent the bulb body from being broken due to thermal expansion of the decoration tube under working conditions.

A bubble tube lamp for decoration, comprising a bulb, an upper lamp cover, a lower lamp cover, and a decorative tube; the bulb includes a bulb body and a conductive copper column, the conductive copper column is provided with an external screw; the bulb body is arranged under the conductive copper column , And located in the upper lamp cover; the lower lamp cover is set under the upper lamp cover, and the lower lamp cover is closed to the upper lamp cover; the decorative tube is set under the lower lamp cover; a through hole is opened in the middle of the lower lamp cover; the through hole is far away A number of fixing pieces are arranged on one side of the upper lamp cover, and the fixing pieces are arranged equidistantly around the periphery of the through hole; a limit mechanism is arranged above the side of the through hole near the upper lamp cover; one end of the decorative tube extends from the inside of the lower lamp cover Outside the cover, the other end passes through the through hole and is clamped and fixed by the limit mechanism.

The utility model relates to a decorative bubble tube lamp. By providing a limit mechanism on the lower lamp cover, the decorative tube can be effectively prevented from expanding due to heat, thereby causing the bulb body to break.

Preferably, the limiting mechanism on the lower lamp cover is a limiting piece; one end of the limiting piece is fixedly connected to the periphery of the through hole, and the other end is bent toward the center of the through hole; in the working state, the decorative tube and the bending in the limiting piece The collision of the folded parts can effectively isolate the decorative tube and the bulb body, thereby preventing the bulb body from breaking.

Further, a limiting piece in the limiting mechanism is provided, and one limiting piece is arranged above the side of the through hole close to the upper lamp cover. There are multiple limiting pieces in the limiting mechanism, and the multiple limiting pieces are equidistantly arranged on the upper side of the through hole close to the upper lamp cover. There are four limit plates in the limit mechanism, and the four limit plates are equidistantly arranged on the upper side of the through hole close to the upper lamp cover.

In order to accelerate the efficiency of the liquid boiling in the decorative tube to generate bubbles, the decorative tube is filled with low-boiling compounds, such as methylene chloride.

In order to prevent the temperature of the bulb body in the upper lamp cover from being too high, the upper lamp cover is provided with first heat dissipation holes for heat dissipation; there are a plurality of first heat dissipation holes, and the plurality of first heat dissipation holes are equidistantly arranged on the upper lamp Cover.

In order to prevent the internal temperature of the lower lamp cover from being too high, the lower lamp cover is provided with second heat dissipation holes for heat dissipation; there are a plurality of second heat dissipation holes, and the plurality of second heat dissipation holes are equidistantly arranged on the lower lamp cover.

The technical effect of a decorative bubble tube lamp is:

By providing a limit mechanism on the lower lamp cover, the decorative tube and the bulb body are separated, which can effectively prevent the decorative tube from being thermally expanded under working conditions, thereby touching the bulb body and causing the bulb body to break.
