BUBBLE-FORMING NOZZLE PLATE FOR BUBBLE BLOWER TOY
A bubble-forming nozzle plate fastened to one end of a blower tube of a bubble blower toy is disclosed, having a front wall adapted for adhering a bubble fluid, a back wall facing the air passage defined in the blower tube and a plurality of jet nozzles cut through the front wall and the back wall in communication with the air passage defined in the blower tube. The jet nozzles have a minimum cross sectional area within the range of 0.07 mm2˜7.07 mm2.
1. Field of the Invention
The present invention relates to a bubble blower toy and more particularly, to a bubble-forming nozzle plate for bubble blower toy, which allows the bubbler blower toy to be blown repeatedly to produce bubbles several times after each application of a bubble fluid.
2. Description of the Related Art
When using a bubble blower toy, the user need to dip the blower tube of the bubble blower toy in a bubble fluid for enabling the bubble-forming nozzle head of the bubble blower toy to be covered with a layer of bubble fluid after removable of the bubble blower toy from the bubble fluid. Thereafter, the user can put the mouthpiece of the bubble blower toy in the mouth and blow air into the bubble blower toy to force the adhered bubble fluid out of the nozzle head, thereby forming bubbles in the air. After each blowing operation, the residual bubble fluid will not be gathered in the holes in the nozzle head for blowing by the user to produce bubbles again. Thus, the user must dip the nozzle head of the bubble blower toy into the bubble fluid again for a next bubble blowing play. It is inconvenient to frequently dip the nozzle head of the bubble blower toy into the bubble fluid when playing the bubble blowing game
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a bubble-forming nozzle plate for bubble blower toy, which allows the bubbler blower toy to be blown repeatedly to produce bubbles several times after each application of a bubble fluid.
To achieve this and other objects of the present invention, a bubble-forming nozzle plate is fastened to one end of a blower tube of a bubble blower toy, comprising opposing front wall and back wall and a plurality of jet nozzles cut through the front wall and the back wall in communication with the air passage defined in the blower tube. The front wall is adapted for adhering a bubble fluid. The back wall faces the air passage defined in the blower tube. The jet nozzles have a minimum cross sectional area within the range of 0.07 mm2˜7.07 mm2.
Referring to
The blower tube 1 comprises an air passage 11 longitudinally extending through the two distal ends thereof, and a mouthpiece 12 located on one end of the air passage 11.
The bubble-forming nozzle plate 2 is fastened to the blower tube 1 and located on the other end of the air passage 11 remote from the mouthpiece 12, having opposing front wall 21 and back wall 23, and a plurality of jet nozzles 22 cut through the front wall 21 and the back wall 23 in communication with the air passage 11. The front wall 21 is adapted for adhering a bubble fluid 4. The back wall 23 faces the air passage 11. The minimum cross sectional area of the jet nozzles 22 is within the range of 0.07 mm2˜7.07 mm2. According to the embodiment shown in
According to the embodiment shown in
Further, the jet nozzles 22 can be circular. However, circular shape is not a limitation, i.e., the jet nozzles 22 can be made having a non-circular cross section. According to the embodiment shown in
Referring to

Referring to
According to test, when the minimum cross sectional area of the jet nozzles 22 is smaller than 7.07 mm2, the chance in which the jet nozzles 22 is refilled by the bubble fluid 4 is relatively increased. However, if the minimum cross sectional area of the jet nozzles 22 is smaller than 0.07 mm2, the fabrication of the bubble-forming nozzle plate 2 will become difficult. Therefore, the minimum cross sectional area of the jet nozzles 22 is set within the range of 0.07 mm2˜7.07 mm2.
In conclusion, the bubble-forming nozzle plate 2 has a plurality of through holes 22 cut through the front wall 21 and back wall 23 thereof, and the minimum cross sectional area of the jet nozzles 22 is within the range of 0.07 mm2˜7.07 mm2. Thus, each time the front wall 21 of the nozzle plate 2 is covered with a layer of bubble fluid 4 and the bubble blower toy is blown to produce bubbles, the residual bubble fluid 4 will be gathered in the jet nozzles 22 subject to the intermolecular cohesive force among the molecules of the bubble fluid 4 for blowing by the user to produce bubbles again.
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.
