Description

A soap bubble play device to prevent backflow {BUBBLE PLAY APPARATUS TO PREVENT BACKFLOW}

The present invention relates to a soap bubble play device for preventing backflow, and more particularly, to a soap bubble play device for preventing backflow that prevents a user from inhaling a bubble solution when making soap bubbles.

In general, a device for making soap bubbles includes a handle held by a person and a circular ring provided at one end of the handle. At this time, if the circular ring is immersed in a solution having the same properties as soapy water and air is blown into the center of the ring, the solution becomes droplets and is discharged from the circular ring.

Conventionally, after injecting a solution capable of generating soap bubbles into the play equipment itself for making soap bubbles, a soap bubble play device that automatically generates soap bubbles from the play equipment using a separate blower has been developed.

However, the conventional soap bubble play device has the inconvenience of having to be careful not to let water or a solution come into contact with the blowing device in order to prevent malfunction of the bubble play device or electric shock to the user when the separate blowing device is electric.

In addition, even if the separate blowing device of the conventional soap bubble play device is a manual type, the weight increases compared to the case where the blowing device is not provided, which puts a burden on the wrist or arm when the user is young. There is a problem that it can.

On the other hand, a soap bubble play device in which a user blows air directly to generate soap bubbles without a separate blowing device has a problem in that a solution for making soap bubbles can be sucked when the user is young.

With respect to the solution used to make soap bubbles, harmful components such as chloromethylisothiazolinone (CMIT) and methylisothiazolinone (MIT), which are components of a humidifier disinfectant, have recently been detected in some soap bubble toys. Exposure to these hazardous ingredients can cause skin reactions, respiratory and eye irritation.

The drop generating unit 200 includes a discharge nozzle 210 , and the discharge nozzle 210 is formed to communicate with the air supply pipe 110 .

After bringing the bubble solution into contact with the discharge nozzle 210 , when air is supplied to the bubble generating unit 200 through the air supply pipe 110 , the bubble solution forms soap bubbles on the discharge nozzle 210 by the air. can do.

At this time, when more air is supplied, the formed soap bubbles may be discharged through the discharge nozzle 210 .

A plurality of discharge nozzles 210 may be formed in the drop generating unit 200 at predetermined intervals.

The solution storage unit 300 forms a space in which the bubble solution is stored, and has an open upper surface, and the space may be connected to the drop generating unit 200 .

For example, the inner surface of the space of the solution storage unit 300 may correspond to the outer surface of the drop generating unit 200 so that the drop generating unit 200 may be detachably coupled to the solution storage unit 300 .

The solution storage unit 300 includes a fitting protrusion 310 , and is disposed at a predetermined interval on the side of the space in which the bubble solution is stored in the solution storage unit 300 .

When the drop generating unit 200 is coupled to the space of the solution storage unit 300, the fitting protrusion 310 engages the drop generating unit 200 to improve the binding force. This will be described with reference to the embodiment of FIG. 8 .

7 is a perspective view illustrating another embodiment of FIG. 1 .

Referring to FIG. 7 , the drop generating unit 200 may be fitted into the space of the solution storage unit 300 as described above. In this case, the user does not need to carry the solution storage unit 300, the bubble generation unit 200 and the body unit 100 separately in both hands, and the present inventor possesses the soap bubble play device 10 for preventing backflow with one hand. and may be movable.

Meanwhile, referring back to FIG. 1 , the solution storage unit 300 has a coupling hole 320 on one side not included in the space.

The coupling hole 320 is formed so that the inner surface corresponds to the outer surface of the other end of the body portion (100). For this reason, the other end of the body part 100 may be detachably coupled to the coupling hole 320 .

In this regard, the coupling hole 320 includes a coupling fitting portion 321, the coupling fitting portion 321 is formed to protrude at a predetermined interval on the inner surface of the coupling hole 320, the other of the body portion 100 When the end is fitted to the coupling hole 320, the coupling force is increased.

FIG. 8 is a perspective view showing another embodiment of FIG. 1 , and is an embodiment of the above-described body part 100 and the coupling hole 320 being fitted.

Referring to FIG. 8 , even in this case, there is an effect that the user can carry and move all the components of the present invention with one hand without the need to separately carry the solution storage unit 300 .

FIG. 2 is a partial cross-sectional view of the main body 100 of FIG. 1 .

Referring to FIG. 2 , the body part 100 may be formed by bending inwardly so that the other end faces one side.

As another example related thereto, the breathing apparatus 120 is formed to extend to the inside of the body part 100 by a predetermined length, and the diameter of the cross-section perpendicular to the longitudinal direction of the breathing apparatus 120 is the inside of the body part 100 It may decrease the further you go.

Due to the above structure, an empty space is formed between the outer surface of the breathing apparatus 120 and the inner surface of the main body 100 .

The user blows air through the breathing apparatus 120 to make soap bubbles using the soap bubble play device 10 for preventing backflow of the present invention, and the user breathes air through the breathing apparatus 120. In this case, the bubble solution buried in the drop generating unit 200 moves to the other end of the body unit 100 along the air supply pipe 110 .

At this time, due to the empty space between the inner surface of the main body 100 and the outer surface of the breathing apparatus 120 , the bubble solution cannot flow out through the breathing apparatus 120 to the outside. That is, even when the user breathes in, the bubble solution does not reach the breathing port 120 through the air supply pipe 110, so it is possible to prevent the user from accidentally inhaling the bubble solution.

3 is a perspective view showing the exterior of the main body 100 and the bubble generating unit 200 of the soap bubble play apparatus 10 for preventing backflow according to the present invention of FIG. 1 .

Referring to FIG. 3 , the drop generating unit 200 includes a discharge groove 211 concavely formed on the surface of the drop generating unit 200 to correspond to the position where the discharge nozzle 210 is formed.

The discharge groove 211 is configured such that the discharge nozzle 210 is disposed therein, and a plurality of discharge nozzles 210 may be disposed on the surface of the drop generating unit 200 at predetermined intervals.

At this time, the discharge groove 211 may be formed in a tapered shape so that the diameter of the cross section perpendicular to the height direction becomes narrower toward the inside.

Also, as another example, the discharge groove 211 may be formed in a hemispherical shape with a concave inner shape.

When the discharge groove 211 is provided, when the soap bubbles pass through the discharge nozzle 210 by the air injected by the user, the contact area between the soap bubbles and the discharge groove 210 increases, so that the soap bubbles do not burst and are discharged stably. can

FIG. 4 is a view showing another embodiment of FIG. 3 , and FIG. 5 is a view showing an embodiment in which the protrusion 212 is added to the drop generating unit 200 of FIG. 4 .

4 and 5, the plurality of discharge nozzles 210 formed on the surface of the drop generating unit 200 is an imaginary line (not shown) passing along the virtual diameter of the surface of the drop generating unit 200 is It may be disposed in the remaining positions except for the

A plurality of protrusions 212 may be formed in the discharge nozzle 210 disposed on the remaining portion except for the virtual line on the surface of the drop generating unit 200 .

The protrusion 212 is formed to penetrate in the height direction and is configured to be connected to the discharge nozzle 210 . At this time, the diameter of the through hole of the protrusion 212 is preferably smaller than the diameter of the discharge nozzle 210, but it is not necessarily small.

When the user uses the bubble play apparatus 10 for preventing backflow corresponding to another embodiment shown in FIG. 5 , the user puts air into the breathing apparatus 120 in a state in which the bubble solution is buried in the protrusion 212 . When blown in, air is delivered to the protrusion 212 through the discharge nozzle 210, so that the bubble solution can be changed into soap bubbles.

In the above case, even if the user inhales air through the breathing apparatus 120 through the breathing apparatus, in order for the bubble solution to reach the breathing apparatus 120, it must pass through the air supply pipe 110 through the through hole of the protrusion 212. Therefore, since the path of the bubble solution to the breathing apparatus 120 is longer than when there is no protrusion 212, considering that the average age of the user is low, in this case, the bubble solution up to the breathing apparatus 120 The probability of reaching by this user's inhalation can be lowered.

6 is a view showing another embodiment of FIG. 5 .

Referring to FIG. 6 , the protrusion 212 disposed on the surface of the drop generating unit 200 so as to be through-connected with the discharge nozzle 210 of the drop generating unit 200 has a central axis in the height direction of the protrusion 212 and It is configured so that the angle formed by the cross section of the surface of the drop generating unit 200 is not vertical.

Specifically, with reference to the imaginary line of the surface of the drop generating unit 200 mentioned with reference to FIGS. 4 and 5 , the central axis in the height direction of the protrusion 212 is symmetrically formed in a direction away from each other. desirable.

When a user uses the embodiment of FIG. 6 , the soap bubbles discharged through the through hole of the protrusion 212 may be formed to move away from each other in both directions based on the virtual line.

In the embodiment of FIG. 6 , it is difficult for the bubble solution to reach the breathing apparatus 120 by the user's inhalation. Since it is the same principle as described above with reference to FIGS. 4 and 5 , a description thereof will be omitted.

Meanwhile, each of the protrusions 212 and the discharge nozzles 210 corresponding to the protrusions 212 may be coupled through a spherical hinge (not shown).

The spherical hinge (not shown) is formed through in the height direction so that air can pass, and the angle in the height direction of the protrusion 212 connected to the discharge nozzle 210 can be changed.

Therefore, since the user can individually adjust the angle of each protrusion 212 by using the spherical hinge, it is possible to diversify the discharge angle of the soap bubble when forming and discharging the soap bubble through the present invention.

FIG. 9a is a view showing before coupling of another embodiment of FIG. 1 , FIG. 9b is a view showing after coupling of FIG. 9a , and FIG. 9c is a view showing a rotational state after coupling of FIG. 9a .

9A, 9B and 9C , the drop generating unit 200 further includes a concave fastening groove 220 disposed at a predetermined interval on the outer surface, and the solution storage unit 300 is a drain hole 330 ) is further included.

In the illustrated embodiment, the fastening groove 220 is configured such that the width of the fastening groove 220 corresponds to the width of the fitting protrusion 310 of the solution storage unit 300 . At this time, it is preferable that the height of the fitting protrusions 310 arranged at predetermined intervals on the inner surface of the solution storage unit 300 is shorter than the height of the inner surface.

Specifically, referring to FIG. 9B , when the drop generating unit 200 is coupled to the solution storage unit 300 , the fastening groove 220 is located below the fitting protrusion 310 .

And referring to FIG. 9c , after the fastening groove 220 of the drop generating unit 200 is coupled to the fitting protrusion 310 of the solution storing unit 300 and passing, the surface of the drop generating unit 200 and the solution storing unit When the body part 100 and the drop generating unit 200 are rotated along the central axis in the longitudinal direction in a state in which the inner lower surface of the 300 is in contact, the fitting protrusion 310 can prevent the drop generating unit 200 from leaving. there will be

Therefore, even if the user holds only a part of the body part 100 in his hand, the drop generating unit 200 and the solution storage unit 300 located at one end of the body unit 100 are coupled to each other and do not come off, so the present invention The whole can be moved easily.

On the other hand, referring again to FIG. 9A , since the drain port 330 is blocked with a drain stopper (not shown), the bubble solution can be stored in the solution storage unit 300 when the user uses the illustrated embodiment.

Even if the drop generating unit 200 connected to the body unit 100 is kept coupled to the solution storage unit 300 after the user uses the illustrated embodiment, the drain blocking the drain port 330 of the solution storage unit 300 is stored. A stopper (not shown) is opened so that the stored bubble solution can be easily discharged through the drain 330 .

For this reason, since the solution remaining in the solution storage unit 300 can be easily dried, it is possible to prevent mold and the like from occurring.

On the other hand, the main body 100, the drop generating unit 200, and the solution storage unit 300 may be formed of an eco-friendly resin (PLA: Poly Lactic Acid) material extracted from corn raw materials.

PLA is made from raw materials extracted from corn starch, and it has the characteristic of being safe because harmful substances such as environmental hormones and heavy metals are not detected. In addition, while in use, it has the same characteristics as general plastics, but when discarded, it is biodegradable by microorganisms, making it an eco-friendly material.

However, the material of the body part 100, the drop generating part 200, and the solution storage part 300 is not limited to the eco-friendly resin (PLA), and may be formed of general plastic or the like according to the user's selection.

In addition, it is preferable that the bubble solution, which is buried in the bubble generating unit 200 of the present invention to form soap bubbles, contains a natural cellulose component.

Therefore, if the user inhales the bubble solution by mouth while using the present invention, it may be possible to prevent a fatal risk to the human body.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains within the scope not departing from the technical spirit and scope of the present invention described in the claims to be described later. It will be understood that various modifications and variations of the present invention are possible.
