BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a lava lamp holder structure improvement, particularly to a lamp holder structure combining a lava lamp and lighting functions.
2. Description of the Related Art
Since the sixties of the last century, lava lamps have become a common device in the worldwide university student dormitories and teenage children bedrooms. Lava lamps have been deeply implanted into the popular culture of the United States and many other countries.
With reference to FIG. 1, U.S. Pat. No. 3,570,156 discloses a lava lamp display device 40 comprising: a glass vessel 41 having a bottom 42 arranged in a hollow conical metallic seating 43 and located on an electric light bulb 44. Moreover, the glass vessel 41 has two immiscible components such as liquid 45 and a paraffin 46 which has a higher density than the liquid 45 at room temperature and a lower density than the liquid 45 after heating. After the electric light bulb 44 is turned on, the paraffin 46 in the bottom 42 of the glass vessel 41 is heated and flows in the liquid 45. At the same time, the electric light bulb 44 projects the light in the glass vessel 41, forming a lighting effect and becoming decorations at home and office.
The principle of the lava lamp is to provide a heat from a bulb for the two kinds of immiscible liquid with different specific gravity within the container to produce convection and the floating objects within the liquid moves up and down. Under the illumination of the projection light, the floating objects float and sink, producing brilliant and vivid visuals.
However, lava lamps have been only for decoration function. Under the long-time use of the lava lamp, the bulb with high temperature is easy to cause a serious burn for those who touch the bulb. Moreover, the transparent container without stable installation structure is easily overturned and broken, which allows the internal liquid to harm human body. Therefore, the present invention is provided for increasing the lava lamp using function, isolating the heat of long-term use of the lava lamp, and enhancing the safety and convenience of the lava lamp.

On the other hand, the external sleeve 22 has air vents 222 at circumference thereof so that the external sleeve 22 is not too high to burn human body.
With the reference to FIGS. 6 and 6A, a transparent bottle 30 has a filler 33 with two immiscible liquid therein. The filler 33 of the transparent bottle 30 may include liquid, paraffin having a higher density than the liquid, or mineral oil which is a prior art and thus will not be described in details here. In the preferred embodiment, the transparent bottle 30 may further include a plurality of paillettes 34. With the reference to FIGS. 6 and 6A, the transparent bottle has an inserted section 31 at a lower end thereof and the inserted section 31 of the transparent bottle 30 has an external diameter slightly smaller than an external diameter of the transparent bottle 30. Moreover, the transparent bottle 30 is arranged between the second mounted seat 13 and the joint sleeve 20 and has a moderate distant d between a bottom 311 thereof and the projection lamp 123.
When installing the transparent bottle 30, the first step as shown in FIG. 3 is to penetrate an upper end 32 of the transparent bottle 30 into the second containing room 131 of the second mounted seat 13 for having a gap of a height h1 between the lower end of the inserted section 31 of the transparent bottle 30 and the upper end of the first mounted seat 12, which is taller than a height h2 of the joint sleeve 20. The second step as shown in FIG. 4 is to penetrate the hollow containing room 211 of the joint sleeve 20 into the inserted section 31 of the transparent bottle 30 so that the bottom of the joint sleeve 20 to the first mounted seat form a space S for installing the projection lamp 123. The third step as shown in FIG. 5 is to move the transparent bottle 30 and the projection lamp 123 downward for the inserted section 212 of the joint sleeve 20 to be penetrated into the first containing room 121. Due to the upper end 32 of the transparent bottle 30 is coated by the second containing room 131 of the second mounted seat 13 and the inserted section 31 is coated by the lip 221 of the joint sleeve 20, the transparent bottle 30 as shown in FIG. 6 in a vertical position is securely installed between the second containing room 131 and the hollow containing room 211. Comparing to the conventional lava lamp 40 as shown in FIG. 1, the present invention with two positioning points on the top and bottom ends of the holder 10 provides safety. A user can follow the first step to the third step in the reverse order to remove the transparent bottle 30.
Whereby the required lighting is available through the lighting lamp 133; the transparent bottle 30 is turned into lava lamp visual effects through an illumination of the projection lamp 123; the heat generated by the projection lamp 123 is isolated by the heat insulation space 23 and the height between the second containing room 131 of the second mounted seat 13 and the hollow containing room 211 of the joint sleeve 20 is slightly higher than the height of the transparent bottle 30 such that the transparent bottle 30 is easy to be installed and removed.
Based on the features disclosed, the present invention provides the lava lamp holder structure to combine heat insulation and heat dissipation functions and a lamp holder structure with a lava lamp transparent bottle which is easy to be installed and removed for increasing the convenience and security effects.
