DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-3, a light-emitting spa bubble massager 100 in accordance with a first embodiment of the present invention is shown comprising an air provider 10, a connection tube 20, an air-driven light source 30 and a bubble bath mat 40.
Referring to FIG. 1 again, the air provider 10 can be an air blower, or any device that uses electricity to produce an output flow of air.
Referring to FIG. 1 again, the connection tube 20 is a flexible tube, for example, hose.
Referring to FIGS. 1-3 again, the air-driven light source 30 comprises a housing 31, a lampshade 32, an electrical generator 33 and a light-emitting module 34. The housing 31 is a waterproof shell formed of two symmetrical halves, having an air inlet 312, and air outlet 313 and an air passage 311 in communication between the air inlet 312 and the air outlet 313. The lampshade 32 is prepared from a waterproof and light-transmissive material, and mounted in one side of the housing 31. The electrical generator 33 is mounted in the air passage 311 inside the housing 31, and adapted for converting kinetic energy into electricity. The light-emitting module 34 is mounted in the housing 31 adjacent to the lampshade 32 and electrically connected to the electrical generator 33 for receiving electricity from the electrical generator 33 and emitting a predetermined color or colors of light toward the lampshade 32.
Referring to FIG. 1 again, the bubble bath mat 40 is to be set in a bathtub under the water, having an air inlet 41 for air in and multiple jet nozzles 42 for output of inputted air to produce bubbles.
Under understanding of the structural details of the light-emitting spa bubble massager 100, the operation and advantages of the light-emitting spa bubble massager 100 will be described hereinafter.
At first, connect the two distal ends of the connection tube 20 to the air provider 10 and the air inlet 312 of the housing 31 of the air-driven light source 30, and then attach the air outlet 313 of the housing 31 of the air-driven light source 30 to the air inlet 41 of the bubble bath mat 40. When in use, put the air-driven light source 30 and the bubble bath mat 40 in the water in a bathtub (or water pool). When the air provider 10 starts to output a flow of air A, the flow of air A goes through the connection tube 20 into the air inlet 312 and air passage 311 of the air-driven light source 30 to move the electrical generator 33, driving the electrical generator 33 to generate electricity for the light-emitting module 34 (see FIG. 2), and therefore the light-emitting module 34 is driven to emit light when the flow of air A is going through the air-driven light source 30. At the same time, the flow of air A keeps going out of the air-driven light source 30 into the air inlet 41 of the bubble bath mat 40 toward the multiple jet nozzles 42, When the flow of air A goes out of the jet nozzles 42 into the water in the bathtub (or water pool), producing bubbles to massage the body of the user bathing in the bathtub (or water pool). Subject to the light emitted by the light-emitting module 34, a visual effect is produced when the user enjoys a bubble-massaging bath.
As the invention utilizes the kinetic energy of the flow of air A to drive the electrical generator 33, no extra power supply is consumed for driving the light-emitting module 34 to emit light, avoiding leakage of the use of an external power source and assuring a high level of safety.
Further, the electrical generator 33 can be a magnetic type or rotor coil type electrical generator.
Further, as shown in FIG. 2, the electrical generator 33 comprises a vane wheel 331, a shaft 332 and a commutator 333. The vane 331 and the shaft 332 are coaxially fastened together, enabling the shaft 332 to be rotated with the vane wheel 331. The commutator 333 is coaxially connected to the shaft 332. According to this embodiment, the vane wheel 331 of the electrical generator 33 is arranged in a parallel manner relative to the extending direction of the air inlet 312, air passage 311 and air outlet 313 of the housing 31. Therefore, when the flow of air goes out of the air provider 10 through the connection tube 20 into the air-driven light source 30, it flows in proper order through the air inlet 312, air passage 311 and air outlet 313 of the housing 31 to rotate the vane wheel 331 and shaft 332 of the electrical generator 33, causing the commutator 333 to induce electricity for driving the light-emitting module 34.
Further, the light-emitting module 34 comprises a control circuit board 341 electrically connected to the electrical generator 33, and a plurality of color LEDs (light emitting diodes) 342 installed in the control circuit board 341 and controlled by the control circuit board 341 to emit light subject to a predetermined operation mode.
Referring to FIG. 3 again, the air-driven light source 30 further comprises a control switch 35 installed in the housing 31 and electrically connected to the light-emitting module 34 for controlling the light emitting sequence and duration of the color LEDs 342 of the light-emitting module 34.
FIGS. 4 ̃7 illustrate a light-emitting spa bubble massager 100 in accordance with a second embodiment of the present invention. This second embodiment is substantially similar to the aforesaid first embodiment with the exception of the locations of the control switch 35 and lampshade 32 the air-driven light source 30 and the arrangement of the vane wheel 331 of the electrical generator 33. According to this second embodiment, the vane wheel 331 of the electrical generator 33 is arranged perpendicular to the extending direction of the air inlet 312, air passage 311 and air outlet 313 of the housing 31.
Thus, similar to the aforesaid first embodiment, when the flow of air goes out of the air provider 10 through the connection tube 20 into the air-driven light source 30 in accordance with the second embodiment of the present invention, the flow of air flows in proper order through the air inlet 312, air passage 311 and air outlet 313 of the housing 31 to rotate the vane wheel 331 and shaft 332 of the electrical generator 33, causing the commutator 333 to induce electricity for driving the light-emitting module 34.
FIGS. 8 and 9 illustrate an air-driven light source for light-emitting spa bubble massager in accordance with a third embodiment of the present invention. According to this third embodiment, the air-driven light source further comprises a waterproof shield 36 and a cover 335. The waterproof shield 36 is an oval shell fitting the lampshade 32 in size. The waterproof shield 36 is mounted inside the housing 31 and affixed to the inner side of the lampshade 32 to surround the light-emitting module 34 for watertight protection. The cover 335 is affixed to the waterproof shield 36 to hold the commutator 333 of the electrical generator 33 on the inside, having an axle hole 337 for the passing of the shaft 332. The vane wheel 331 is affixed to one end of the shaft 332 outside the cover 335. Further, a waterproof stuffing material may be filled in the cover 335 around the commutator 333.
Further, the waterproof shield 36 comprises a plate member 360 perpendicularly extended from its one side for supporting the cover 335 and the commutator 333 in the cover 335, and a substantially V-shaped bottom wall 361 that has two distal ends thereof connected to the bottom side of the plate member 360.
The vane wheel 331 of the electrical generator 33 is mounted in the air passage 311 in a parallel manner relative to the extending direction of the air inlet 312, air passage 311 and air outlet 313 of the housing 31 such that when the flow of air flows through the air inlet 312, air passage 311 and air outlet 313 of the housing 31, it rotates the vane wheel 331 and shaft 332 of the electrical generator 33, causing the commutator 333 to induce electricity for driving the light-emitting module 34. Further, the V-shaped bottom wall 361 of the waterproof shield 36 facilitates smooth and rapid flowing of the flow of air through the air passage 311 of the housing 31 toward the air outlet 313.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
