Detailed Description of the Embodiments

The present disclosure will be explained below in conjunction with the accompanying drawings1to5.

The present disclosure provides a bubble lamp for decoration, including a bubble tube1and a heating bulb2which are used cooperatively. In order to ensure the safety of the bubble tube1, the bubble tube1is made of glass and is sealed. A small space is reserved at a top of the bubble tube1. Low-boiling-point liquid11is injected into the bubble tube1; the heating bulb2includes a lamp holder21, a bulb shell22, and a heating light source23; the bulb shell22is fixedly connected to the lamp holder21; and the heating light source23is electrically connected to the lamp holder21. When the lamp holder21is connected to an external power supply to light up the heating light source23, light of the heating light source23directly irradiates the bubble tube1, and the light echoes with the liquid inside the bubble tube1to create a more beautiful lighting effect. Secondly, heat generated by the heating light source23through the electricity will also reach the low-boiling-point liquid11inside the bubble tube1through the bubble tube, so that the liquid is boiled to continuously generate bubbles inside the bubble tube1. This transforms a static decorative lamp into a dynamic and vivid decorative lamp and adds fun to the lamp. Decorative objects such as glitters can also be added to the bubble tube1, and the decorative objects can float up and down under the action of a bubble flow to improve the decoration effect of the lamp. In addition, to accelerate the generation of the bubbles, a fixed catalysis layer12is arranged at one end of the bubble tube1facing the heating light source23.

As an embodiment, the low-boiling-point liquid11may use dichloromethane. The dichloromethane is a low-boiling-point organic compound with a boiling point of only 39.8° C., which meets the use requirements of this technical solution. Secondly, the dichloromethane has low toxicity, is inflammable at a room temperature, has high safety, and is suitable for industrial batch production.

In this technical solution, the catalyst layer12is a mixture of sodium silicate and glass splinters. The glass splinter is an irregular solid substance. Under the action of the sodium silicate, the glass splinters are fixed at an inner bottom of the bubble tube1and cause gaps of different sizes. When the dichloromethane at the bottom of the bubble tube1begins to be boiled when heated, the bubbles are separated through the irregular gaps to form more small bubbles, so that the bubble tube1can produce more and more obvious bubble flows.

Since it takes time that the heat generated by the heating bulb2makes the dichloromethane reach the boiling point, to shorten the reaction time, the bubble tube1is internally vacuumized, which can further reduce the boiling point of the dichloromethane, with a vacuum degree between −5 kPa and −10 kPa. This can achieve that the bubble tube1can quickly generate the bubbles once the bulb is lit up.

In this technical solution, the lamp further includes an outer decorative lampshade3; a bottom end of the outer decorative lampshade3is provided with a bayonet31; a top end of the outer decorative lampshade3is provided with a first insertion hole32configured to assemble the bubble tube1; the heating bulb2is assembled inside the outer decorative lampshade3; and the lamp holder21extends out of the bayonet31to facilitate electrical connection to an external device. The outer decorative lampshade3can be configured to assemble the heating bulb2and the bubble tube1and hide a joint between the bubble tube1and the heating bulb2, which improves the aesthetic degree of the lamp.

Preferably, a circumferential side of the first insertion hole32extends towards an outer end to form several elastic parts321; the several elastic parts321are spaced apart from one another and distributed in a surrounding manner to form an annular limiting part324to limit the bubble tube1and ensure the stable assembling of the bubble tube1; and the elastic parts321are all provided with ribs322. Due to the thermal expansion and cold contraction properties of the glass bubble tube1, it is difficult to control the size during molding, and the bubble tube1may easily have a large size or a small size. In this case, the elastic parts321and the ribs322can be used to adapt to the size of the bubble tube1, so as to enlarge the application range of the outer decorative lampshade3.

As an embodiment, the bayonet31is provided with a notch311. When the lamp holder21is welded to a conductive wire of the heating light source23, a solder point with a large volume will appear and protrudes out of one side of the lamp holder21. In this case, the notch311exactly accommodates the solder point.

Preferably, for convenience of assembling and disassembling of the outer decorative lampshade (3), the outer decorative lampshade3includes a housing33and an end cover34connected to the housing33; the end cover34is provided with at least one group of connecting protruding points341; and the housing33is provided with connecting recesses331corresponding to the connecting protruding points341. The housing33and the end cover34are detachably connected through the connecting protruding points341with a simple structure and the connecting recesses331with a simple structure.

When the heating light source23is a tungsten filament, the heating bulb2is a tungsten filament bulb, and the bulb shell22is a glass bulb shell22. The tungsten filament bulb has high heating efficiency and a higher heating temperature. The bubble tube1only needs to resist against a surface of the glass bulb shell22to make the dichloromethane boiled and generate bubbles.

When the tungsten filament bulb is used, as the bulb shell22and the bubble tube1are both made of a glass material, to prevent glass from colliding each other to be damaged during transportation or use, a bottom end of the first insertion hole32extends downwards and is provided with an isolation frame323to isolate the glass bulb shell22from the bubble tube1. Furthermore, the isolation frame323is formed by a plastic material with a good heat conductivity coefficient, so that the isolation frame323will not affect the transferring of the heat. On the other hand, the isolation frame323has a positioning function. In a lamp forming process, a depth of the isolation frame323can be set in advance, so as to position an assembling depth of the bubble tube1.

As another embodiment, when the heating bulb2is an LED bulb, as shown inFIG.4, the heating light source23includes a power board231and an LED232mounted on a surface of the power board231. Due to the fact that the heating efficiency of the LED232is higher than that of the tungsten filament bulb, the bulb shell22can be formed by plastic. In this case, a second insertion hole221can be formed in a top end of the bulb shell22. The bubble tube1is inserted into the second insertion hole221and resists against the LED232to limit the bubble tube1and cause the heat of the LED232to be quickly transferred to the bubble tube1. In this embodiment, a circle of glue can be directly applied to a circumferential side of the second insertion hole221to connect and form the bubble tube1and the heating bulb2. The outer decorative lampshade3can be added outside or the lamp can be directly used without the outer decorative lampshade3, so that the use and manufacturing costs are lower.

As another embodiment, a surface of the outer decorative lampshade3is provided with several through holes4to embellish the outer decorative lampshade3and also to dissipate heat inside the lampshade.

The content of this specification should not be understood as a limitation on the present disclosure.
