Description

[Technical Field]

[0001] The present invention relates to a toy that generates bubble rings (ring-shaped bubbles) that move in all directions 360 degrees in water. [Background technology]

[0002] Proposals for generating bubble rings without using power include the "Self-Priming underwater device for generating or shooting a vortex ring" (see Patent Document 1), the "Water Play Toy" (see Patent Document 2), and the "Bubble Ring Generating Toy" (see Patent Document 3), which are publicly known technologies.

[0003] Among these, it has been revealed that the "Bubble Ring Generating Toy" (see Patent Document 3) can generate bubble rings horizontally with a relatively simple structure. [Prior art documents] [Patent documents]

[0005] However, while it is possible to generate bubble rings horizontally underwater, if the device is held vertically upward, air will leak from the air container, making it impossible to generate bubble rings vertically upward.

[0006] Furthermore, when the main body is oriented vertically downward, the air inside the expansion tube is not drawn into the vortex formed near the nozzle tube, and a bubble ring cannot be generated vertically downward. [Means for solving the problem]

[0007] The toy that generates bubble rings according to claim 1 of the present invention has a structure that includes an outlet tube 1 at the front end, an expansion tube 2 connected to the outlet tube 1 and having an inner diameter larger than that of the outlet tube 1, a reduction tube 3 connected to the expansion tube 2 and having an inner diameter smaller than that of the expansion tube 2, and a mouthpiece tube 4 connected to the reduction tube 3 and having an inner diameter smaller than that of the reduction tube 3. By submerging the body in water, expelling all the air inside, holding the mouthpiece tube 4 in the mouth, and blowing air out instantly, water and air are sprayed out from the outlet tube 1, and the air is drawn into a vortex formed near the outlet tube 1, generating bubble rings that move in all directions 360 degrees. [Effects of the Invention]

[0008] The bubble ring generating toy of the present invention allows children to generate bubble rings in all directions 360 degrees when playing in a bathtub or pool, making it a fun experience.

[0009] Furthermore, the toy of the present invention that generates bubble rings that move in all directions 360 degrees has the advantage of being extremely simple in structure and inexpensive to manufacture. [Brief explanation of the drawings]

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a toy according to the present invention that generates bubble rings in all directions of 360 degrees will be described below in detail with reference to the accompanying drawings.

[0012] It should be noted that the examples shown below are merely illustrative, and the dimensions, shape, material, etc. of the toy that generates bubble rings that move in all directions 360 degrees according to the present invention may be changed within the scope that does not deviate from the spirit of the present invention. [Example]

[0013] The embodiment shown in Figure 1 is a toy A that generates bubble rings that move in all directions 360 degrees. The toy A that generates bubble rings in all directions 360 degrees includes a nozzle tube 1, an expansion tube 2, a contraction tube 3, and a mouth tube 4.

[0014] FIG. 2 is a schematic perspective view showing the entire toy that generates bubble rings that move in all directions 360 degrees. Toy A, which generates bubble rings in all directions 360 degrees, is made by inserting the rear end of circular tube B, which is made of, for example, general-purpose plastic and is made by connecting nozzle tube 5 and expansion tube 6, into the front end of circular tube C, which is made by connecting expansion tube 6 and reduction tube 7, and then inserting the front end of circular tube D, which is made by connecting reduction tube 7 and nozzle tube 8, into the rear end of circular tube C and fixing them in place.

[0015] Toy A, which generates bubble rings that move in all directions 360 degrees, is submerged in water when bathing in a bathtub or pool. After expelling all the air from inside the toy, the user holds nozzle tube 4 in their mouth and instantly blows out air. The compressed air passes through contracting tube 7 and is released from pressure inside expanding tube 6. The restoring force pushes out the water, and water and air are ejected from the tip of outlet tube 5. The difference in speed between the flowing water area at the tip of outlet tube 5 and the still water area near the outlet creates a vortex, and the air that flows out of outlet tube 5 is drawn into the vortex, generating bubble rings that move in all directions 360 degrees.

[0016] Next, the following provides examples of dimensional conditions for a toy that generates bubble rings moving in all directions 360 degrees according to the present invention. Figure 3 shows longitudinal cross-sectional views of a circular tube with various dimensional conditions. Experiments were conducted under the following conditions: the nozzle tube inner diameter E was fixed at φ18.75 mm, the expansion tube inner diameter F was fixed at φ31.25 mm, the reduction tube inner diameter G was fixed at φ12.5 mm, the nozzle tube length I was fixed at 12.5 mm, the expansion tube length J was fixed at 75 mm, and the nozzle tube length L was fixed at 12.5 mm. Three nozzle tube inner diameters H were used (φ3.1 mm, φ6.25 mm, and 9.4 mm), and three reduction tube lengths K were used (40 mm, 100 mm, and 160 mm). The nozzle tube, expansion tube, and reduction tube were 1.25 times larger than the conditions under which good bubble ring formation was achieved in an experiment using a "bubble ring generating toy" (see Patent Document 3). The dimensions before multiplying by 1.25 are: nozzle outlet pipe inner diameter E = 15 mm, expansion pipe inner diameter F = 25 mm, reduction pipe inner diameter G = 10 mm, nozzle outlet pipe length I = 10 mm, expansion pipe length J = 60 mm.

[0017] In the experiment, tests were conducted in vertically upward, horizontal, and vertically downward directions, and the shape of the bubble rings was visually confirmed. The ○ and × symbols in the table are visual evaluations based on visual confirmation, with ○ indicating that the bubble rings were good, and × indicating that they collapsed midway and were not satisfactory.

[0018] [Table 1]

[0019] Table 1 shows the inner diameter H of the nozzle pipe and the reduced pipe length. K The results show the formation of bubble rings when the inner diameter H of the nozzle tube is φ3.1 mm, and the reduced tube length is K It can be seen that no bubble rings are formed even when the reduced pipe length is changed. K When the nozzle length is 40 mm, bubble rings do not form even if the nozzle pipe inner diameter H is changed. K However, 100mm is better than 160mm, and the inner diameter H of the nozzle tube is better than φ9.4mm.

[0020] From the above experiment, the conditions for forming good bubble rings in the nine patterns of Example 1 were: inner diameter H of the nozzle tube of φ6.25 mm, reduced tube length K is 100mm. [Example]

[0021] Next, a second embodiment of the present invention will be described. In the toy that generates bubble rings that move in all directions 360 degrees, the inner diameter of the contracting tube is gradually narrowed and smoothly joined to the nozzle tube, making it possible to push out all the water remaining in the corners of the contracting tube. [Example]

[0022] Next, a third embodiment of the present invention will be described. In the toy that generates bubble rings that move in all directions 360 degrees, as described in claim 3, the shape of the nozzle tube is oval to fit the shape of the lips, making it easier to blow air instantly. [Industrial Applicability]

[0023] The toy of the present invention can be used as a plaything when bathing in a bathtub or a pool, and demand for it is expected. [Explanation of symbols]
