Description

Technical Field

[0001] The utility model relates to the technical field of stage special effect equipment, in particular to a device capable of generating bubbles containing smoke. Background Art

[0002] There are many different types of bubble machines, one of which is that the bubble liquid forms a liquid film across a ring, and guides air through the opening in the ring to form bubbles. For example, a bubble ring with at least one circular or oval opening is provided, and the bubble ring is inserted into an open container containing bubble liquid. After the bubble ring contains the bubble liquid and forms a liquid film, a fan blows air toward the bubble ring, so that the liquid film forms bubbles and leaves the bubble ring. However, since the container of the bubble liquid is open, the bubble liquid is easily scattered on the stage due to the movement or shaking of the equipment, and then there is a danger of causing the actors to slip; and the bubble liquid in the open container will evaporate after being placed for a period of time, causing the bubble liquid to fail.

[0003] The existing smoke machine and bubble machine are basically independent of each other. Bubbles are mixed into the smoke so that the smoke and bubbles are mixed together to form a stage effect of smoke and bubbles coexisting, but smoke cannot be poured into the bubbles to form a better stage effect. In addition, the oil mist formed by heating and vaporizing the smoke oil has a high temperature after being sprayed from the nozzle of the heating element. It is easy to cause the bubble to burst when filled in the bubble, and the stability and durability of the bubble are reduced. Utility Model Content

[0033] A smoke bubble machine according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0034] See also Figures 1 to 5 According to an embodiment of the utility model, a smoke bubble machine includes a smoke generating system, a smoke chamber 1, and a bubble forming system.

[0035] The smoke generating system is used to generate smoke, and includes a heating device 2 and a smoke oil transfer device. After the smoke oil transfer device transfers the smoke oil from the smoke oil supply source 6 to the heating device 2, the heating device 2 heats the smoke oil to vaporize it into smoke.

[0036] The heating device 2 may include a heating channel, a heating element, and a smoke nozzle 3. When the heating element is working, the temperature of the heating channel can be increased. When the smoke oil flows through the heating channel, it absorbs the heat of the heating channel, and after reaching the vaporization temperature, it vaporizes into smoke and is finally ejected from the smoke nozzle 3. The heating element may be an electric heating wire or electric heating tube wound around the heating channel, or other heating elements that can directly or indirectly increase the temperature of the smoke oil flowing through the heating channel to the vaporization temperature. The specific structure of the heating element is not limited in this embodiment.

[0037] The smoke oil transfer device may include a smoke oil pipeline 4 and a delivery pump 5 . When the delivery pump 5 is in operation, the smoke oil in the smoke oil supply source 6 is transferred to the heating device 2 through the smoke oil pipeline 4 .

[0038] The smoke oil transfer device may further include a smoke oil supply source 6, such as a barrel storing smoke oil. The smoke oil pipeline 4 may extend into the smoke oil supply source 6, and the smoke oil may be pumped out by a delivery pump 5. The delivery pump 5 may be an electromagnetic pump, and the smoke bubble machine may further include a control circuit 7 for controlling the operation of the smoke bubble machine, and the control circuit 7 is electrically connected to the delivery pump 5, the heating device 2, etc. It should be understood that the smoke oil transfer device may also adopt other suitable structures, which are not listed here one by one.

[0039] The smoke chamber 1 is a space for receiving and cooling the smoke generated by the smoke generating system. The smoke enters the smoke chamber 1 after being ejected from the smoke nozzle 3. Specifically, the smoke chamber 1 is formed with an air inlet 8, and the smoke nozzle 3 of the heating device 2 extends into the cooling chamber through the air inlet 8, or extends into the cooling chamber through a mounting hole adjacent to the air inlet 8. After the smoke is ejected from the smoke nozzle 3, the airflow formed by it can drive the air outside the smoke chamber 1 to enter the smoke chamber 1 through the air inlet 8. After the air enters from the air inlet 8, the smoke can be cooled in time to avoid or reduce the condensation of the smoke due to contact with the inner wall of the smoke chamber 1. The smoke chamber 1 can be made of a material with good thermal conductivity, such as a steel plate, an aluminum plate, etc. During the smoke's stay in the smoke chamber 1, the temperature of the smoke can be further reduced by heat exchange with the inner wall of the smoke chamber 1.

[0040] The bubble forming system includes a bubble generating device 9 and a bubble liquid transfer device. The number of the bubble generating devices 9 is N, and N is greater than or equal to 2. For example, the number of the bubble generating devices 9 can be 4, arranged side by side in the horizontal direction, and each bubble generating device 9 can generate one bubble at the same time. It should be understood that the specific number of the bubble generating devices 9 can be set according to the number of bubbles to be ejected simultaneously required in a specific application scenario.

[0041] See now Figures 6 to 8 Each of the bubble generating devices 9 includes a first fan 10, an air duct 11, a film former 12, and a brush rod assembly 13. The film former 12 is arranged at the outlet of the air duct 11, and the outer peripheral wall of the film former 12 is formed with a plurality of ridges protruding outwards distributed along the circumferential direction. The bubble liquid transferred from the bubble liquid supply source 23 to the film former 12 by the bubble liquid transfer device moves from the rear end of the film former 12 along the ridge to the front end of the film former 12. Under the action of the brush rod assembly 13, the bubble liquid forms a liquid film at the edge of the front opening of the film former 12.

[0042] The brush rod assembly 13 includes a bracket 14 and a brush rod 15 fixed to the bracket 14. The bracket 14 can be rotatably mounted on the outside of the air duct 11 and swing back and forth under the action of external force. During the swinging process of the bracket 14, the brush rod 15 slides along the front end opening edge of the corresponding film former 12, causing the bubble liquid to form a liquid film at the front end opening edge of the film former 12. When the first fan 10 is working, it causes the mixed smoke composed of smoke and air in the smoke chamber 1 to be blown toward the film former 12 through the air duct 11, and causes the liquid film to form bubbles that wrap the mixed smoke.

[0043] Specifically, each of the brackets 14 can be connected by the same connecting frame 16, and the same driving mechanism 17 can drive each bracket 14 to swing synchronously. The synchronous swinging of each bracket 14 can make each brush rod 15 slide synchronously along the front end opening edge of the corresponding film former 12, and then synchronously form a liquid film at the front end opening edge of each film former 12. Under the premise that each first fan 10 works synchronously and the flow rate of the mixed smoke blown to the film former 12 through the air duct 11 is the same, bubbles wrapping the mixed smoke will be formed at the same time and blown out. The connecting frame 16 can be a rigid structure rigidly connected to the same part of each bracket 14. The driving mechanism 17 can directly drive one of the brackets 14 to swing, and transmit power to the remaining brackets 14 through the connecting frame 16, driving the remaining brackets 14 to swing.

[0044] Now back to Figures 4 to 5 The first fans 10 and the driving mechanism 17 can be electrically connected to the control circuit 7, and their operation is controlled by the control circuit 7. Each of the first fans 10 is arranged in the smoke chamber 1 and fixed to the inner bottom surface of the smoke chamber 1 through the pressing plate 18. When the first fans 10 are working, the air outside the smoke chamber 1 can also be driven to enter the smoke chamber 1 through the air inlet 8.

[0045] In this embodiment, the bubble liquid transfer device includes a main pipeline 19, N branch pipelines 20, and N pumps 21. Each pump 21 is used to drive the bubble liquid from the bubble liquid supply source 23 to be transferred to the corresponding film forming device 12 through the main pipeline 19 and the corresponding branch pipeline 20 in sequence. The pump 21 can be a peristaltic pump, and each pump 21 can be electrically connected to the control circuit 7, and its operation is controlled by the control circuit 7.

[0046] Return now Figure 2 A recovery tank 22 may be arranged below the film former 12 to receive the bubble liquid dripping from the film former 12 and the brush rod 15. The bubble forming system may also include a bubble liquid supply source 23, which may be a barrel storing bubble liquid. A liquid collecting hole 24 is provided at the bottom of the recovery tank 22, and the liquid collecting hole 24 is connected to a recovery pipe 25, so that the bubble liquid in the recovery tank 22 can flow back to the bubble liquid supply source 23 through the liquid collecting hole 24 and the recovery pipe 25 in sequence.

[0047] See now Figure 1 , Figure 2 and Figure 4 , the smoke bubble machine may further include a bubble booster. The bubble booster includes a second fan 26, and an air guide plate 27 arranged at the air outlet of the second fan 26. The air guide plate 27 is used to adjust the flow direction of the airflow generated by the second fan 26, so that the airflow drives the bubbles to move in a set direction. The second fan 26 may be electrically connected to the control circuit 7, and its operation is controlled by a control motor. The number of the second fans 26 may be set according to specific circumstances, for example, according to the distance that the bubbles need to move, the air volume of the second fan 26, the number and position of the bubble generating device 9, and so on. For example, in the present embodiment, the number of the second fans 26 is three, which are arranged side by side in the horizontal direction.

[0048] In this embodiment, the air guide plate 27 includes a guide plate 28 and two side plates 29. The two side plates 29 are symmetrically arranged and are respectively fixedly connected to the two side edges of the guide plate 28. Each side plate is rotatably connected to the corresponding fan side plate at the air outlet of the second fan 26, and rotating the air guide plate 27 can adjust the flow direction of the airflow generated by the second fan 26.

[0049] At least one of the side plates 29 is formed with an arc-shaped guide groove 30 and a plurality of positioning holes 31. The positioning holes 31 of the same side plate 29 are located on the same virtual circle. A guide column 32 and a positioning bead 33 are fixed to the fan side plate rotatably connected to the side plate 29. The guide column 32 extends into the arc-shaped guide groove 30 and cooperates with the arc-shaped guide groove 30 to limit the angular range of rotation of the air guide plate 27. During the rotation of the air guide plate 27, the ball of the positioning bead 33 can be sequentially extended into each positioning hole 31. The cooperation between the positioning bead 33 and the positioning hole 31 can make the air guide plate 28 stay at the corresponding angle, thereby making the airflow generated by the second fan 26 flow in the corresponding direction.

[0050] See now Figure 1 In this embodiment, the smoke bubble machine further includes a shell 34. The smoke generating system, the smoke chamber 1, the bubble forming system, and the second fan 26 are all installed inside the shell 34. The shell 34 is formed with an air outlet, and the air guide plate 27 can close the air outlet when it is in the folded state. The upper edge of the guide plate 28 protrudes outward to form an opening portion 35, and the air guide plate 27 can be easily converted from the folded state to the expanded state through the opening portion 35. The shell 34 also forms N smoke bubble ports 36 opposite to each film former 12, and the bubbles leave the shell 34 through the smoke bubble ports 36.

[0051] In this embodiment, the air outlet is located below the smoke bubble port 36. When the air guide plate 27 is in the unfolded state, the air guide plate 28 extends out of the shell 34 and can make the airflow generated by the second fan 26 flow upward obliquely.

[0052] The smoke bubble machine of this embodiment uses air to cool the smoke in time, avoiding or reducing the condensation of the smoke due to contact with the inner wall of the smoke chamber. After the cooled smoke is filled into the bubble, the stability and durability of the bubble are less affected, and the bubble is not easy to break. The smoke bubble machine of this embodiment can generate N (N is greater than or equal to 2) bubbles at the same time, and the bubble quantity is large.
