Bubble lamp structure for qusai air bubble flow

Disclosed is a bubble lamp for quasi bubble flow. A buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken.

(a) TECHNICAL FIELD OF THE INVENTION

The present invention relates to a lamp structure, and more particularly to a bubble lamp structure, inside which quasi air bubble flow is generated by means of high temperature.

(b) DESCRIPTION OF THE PRIOR ART

A bubble lamp for quasi bubble flow is a lamp having a bulb on which a glass tube inside which quasi bubble flow is generated by means of high temperature is configured. The bubble lamp for quasi bubble flow, asFIG. 1shows, mainly includes a main body10, upper cover20, bulb30and glass tube40inside which fluid41with a low boiling point and several fine color particles42. An opening is configured on the top of the main body10, and a smaller circular hole the bottom thereof; the bulb30is placed on the main body10, and a screw base31on the bottom of the bulb30is passed through the circular hole to expose out of the main body10; an opening is configured on the bottom of the upper cover20, and a smaller circular hole the top thereof; the glass tube40is inserted in the upper cover20through the circular hole, and the upper half of the glass tube40is exposed out of the top of the upper cover20. Upon assembly, the upper cover20is covered on and fixed to the main body10, while the top of the bulb30is allowed to be contacted with and abutted against the bottom of the glass tube40. As arranged, the bulb30will generate high temperature heat energy after it is lighted; the heat energy can be not only radiated by air conduction but transmitted quickly to the glass tube40through the contact in such a way to allow the fluid41with a low boiling point to flow vertically inside the glass tube40due to the heat energy, and thus drive the fine color particles42also to flow vertically with it so as to form a quasi bubble flow pattern, thereby allowing the bubble lamp to have not only dazzle bright lighting but the contrast of quasi color bubble flow to promote the visual effect of the bubble lamp.

But, the bubble lamp structure mentioned above has the defects: the glass-made glass tube and bulb must be abutted against each other after assembly, and the best heat conduction effect can then be achieved. However, if the contact force between the glass tube and bulb is too large upon assembly, one of them is easy to be broken. Furthermore, the glass tube and bulb are expanded due to temperature change upon the direct contact and abutment thereof to cause them to push each other, probably resulting in the rupture thereof. Therefore, conventional bubble lamp structures are not ideal, necessary to be improved.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a bubble lamp structure for quasi bubble flow, preventing a glass tube or bulb from being damaged easily upon the assembly or use of the bubble lamp.

To achieve the object mentioned above, the solution is that a buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken. Furthermore, the heat generated from the bulb can be conducted effectively to the glass tube. In addition, the glass tube can be prevented from being broken due to collision, or the fragments of the glass tube can be maintained in the casing without scattering around to cut people close to the bubble lamp when the glass tube is subject to a larger external force and is thus compressed or struck to break because the casing is put around the glass tube.
