DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Referring to FIGS. 1 to 3, a resistance water lamp, in a preferred embodiment, mainly includes a main body 1 and accommodation tank 2, where the main body 1 is made of plastic material by means of injection or blow molding, and is a transparent hollow three-dimensional shape. The main body 1 includes a shell 11 and bottom cover 12, where the bottom of the shell 11 has an opening 111 facing downward, and the bottom cover 12 is configured on the bottom of the shell 11 and adapted to seal the opening 111; the inside of the shell 11 is filled with low boiling point liquid, which is a mixed solution of water and calcium nitrate in an appropriate proportion. In the embodiment, the shell 11 is exemplified as a Christmas tree body to describe, but the present invention is not so limited, it can be a sphere, a square, a polyhedron or other natural objects. In addition, glitter powder and/or sequins can be added to the liquid, so that the flow of the liquid can bring different visual changes to consumers.

[0011] The accommodation tank 2 is configured with an opening 21, and fixed to one side of the main body 1 with the opening 21; the inside of the accommodation tank 2 is configured with an electric control unit 3 including a circuit board 31, at least one electric heater 3, at least one light-emitting element 31 and power source 34, where the electric heater 32, light-emitting element 33 and power source 34 are respectively electrically connected with the circuit board 31, which can control the flicker frequency and light color change of the light-emitting element 33 through a circuit design. However, the circuit design can be changed in many ways and is not the focus of the present invention, so the detail thereof is omitted here.

[0012] The power source 34 is adapted to provide the electric heater 32 and light-emitting element 33 with power, and the present invention does not limit the type of the power source 34; it can be mains or battery. Furthermore, the present invention also does not limit the number of the electric heaters 32 and the one of the light-emitting elements 33, and they can be increased depending on the structural design. In the embodiment, a plurality of electric heaters 32 and a plurality of light-emitting elements 33 are shown in the figures, but the present invention is not so limited. In addition, the electric heater 32 may be an electric heating wire, electric heating piece, cement resistor or incandescent bulb.

[0013] As mentioned above, in order to directly conduct the thermal energy of the electric heater 32 and the light-emitting element 33 to the side of the main body 1, the electric heater 32 and light-emitting element 33 are preferably formed a close contact with the side of the main body 1. In addition, the electric control unit 3 further includes a switch 35, through which the power source (mains or battery) can be conducted and closed. Furthermore, each of the electric heaters 32 is allowed to be energized to generate heat energy, and the circuit board control the time sequence of the light color changes of each of the light-emitting elements 33.

[0014] Referring to FIG. 3, each of the electric heaters 32 will produce the thermistor effect and generate heat energy to drive the liquid inside the main body 1 to create dynamic effects of bubble flow when the power source 34 is energized. In addition, the flowing liquid is then irradiated by each of the light-emitting elements 33 to form a water lamp structure with dynamic light and shadow changes. It is worth mentioning that, the present invention uses an appropriate ratio of calcium nitrate and water, capable of reducing harm to health and influence to the environment, and the main body 1 is made of plastic material, having the advantages of reducing collision damage during handling and being convenient for storage compared to the prior art glass products.

[0015] Next, referring to FIG. 4, the main body 1, in another preferred embodiment, is a star body, inside which low boiling point liquid is filled, where the liquid is mixed solution of an appropriate ration of water and calcium nitrate; the accommodation tank 2 is a Christmas tree-shaped body, fixed to one side of the main body 1, where the wall of the accommodation tank 2 adjacent to the opening 21 is provided with a shoulder 22, and the circuit board 31 of the electric control unit 3 is mounted on the shoulder 22 to make the electric heater 32 and light-emitting element 33 attach to the side of the main body 1, thereby allowing them to drive the liquid inside the main body 1 to generate the dynamic effects of flowing bubbles with the heat energy produced by them.

[0016] As mentioned above, the shoulder 22, in the embodiment, is adapted to mount and fix the electric control unit 3, allowing the electric heater 32 to be close to the bottom of the main body 1. Therefore, any structure that can be used to fix the electronic control unit 3 or make the electric heater 32 close to the bottom of the water lamp body 1 falls in the scope of this present invention.
