Description

Technical Field

[0001] This invention relates to the field of entertainment performance equipment technology, and in particular to a device and method for generating fire-breathing bubbles that can produce a variety of visual effects of interactive flame and bubble interaction and has four jet modes. Background Technology

[0002] Bubble effects are widely popular in stage performances, theme parks, and large-scale entertainment events due to their dreamlike and fun visual appeal. Traditional bubble machines can only produce ordinary bubbles, lacking dynamic changes and thrilling elements. In recent years, some devices have emerged that can produce smoke bubbles, but their visual effects remain relatively simple. Combining flame jet effects with bubbles to create "fire-breathing bubbles" would greatly enhance the impact and visual appeal of the performance. However, no publicly available technology can safely and controllably generate a combustible gas mixture that can be sprayed in multiple directions and allows for flame transfer between bubbles. Therefore, developing a fire-breathing bubble device capable of producing various combined flame and bubble effects has significant market application value. Summary of the Invention

The invention will be further described in detail below with reference to the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the invention.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0016] Example 1: Specific Structure of the Device See Figures 1 to 7This embodiment provides a device for generating flame bubbles. The base (11) is a square steel plate box, which houses a liquid storage tank (21), a liquid pump (22), a fan (28), a smoke generating module (29), and a gas storage tank (210). The vertical hollow tube (12) is a square steel tube, with its lower end hinged to the base (11) via an adjustable hinge (14), and its upper end hinged to the horizontal hollow tube (13) via another adjustable hinge (14). A flame nozzle (16) is welded to the end of the horizontal hollow tube (13), which is trumpet-shaped and has its axis perpendicular to the horizontal hollow tube (13). A first adsorption ring (151) is fixed to the lower surface of the middle part of the horizontal hollow tube (13), and a second adsorption ring (152) is fixed to the upper surface. A first bubble outlet (171) is provided on the lower wall of the horizontal hollow tube (13), and a second bubble outlet (172) is provided on the upper wall. A transparent annular component (283) connects the first adsorption ring (151) and the second adsorption ring (152) to the nozzle (16). The transparent annular component (283) is annular and made of acrylic material, providing a continuous annular adsorption surface for the bubbles. Through holes are provided on the transparent annular component (283) at positions corresponding to the first bubble outlet (171) and the second bubble outlet (172) to ensure that the bubble outlets are not blocked, allowing the bubbles to be blown out smoothly from the bubble outlets and grow along the surface of the annular component. Its surface is smooth, making it easy for the bubbles to slide along the annular surface. When using it for the first time, the surface of the transparent annular component (283) needs to be wetted with bubble solution to enhance the adsorption force and sliding properties of the bubbles, ensuring that the bubbles can grow stably along the annular component and cover the nozzle (16).

[0017] The liquid guide tube (23) is a silicone tube with 0.3mm micropores at the adsorption ring and the nozzle. The absorbent material (24) is a high-temperature resistant sponge (not shown in the figure). Two geared motors (271, 272) are installed on the upper surface of the transverse hollow tube (13), with the output shaft extending into the tube and fixedly connected to the transverse rotating rod. The other end of the transverse rotating rod is connected to the connecting rod on the scraper valve through a bearing. The scraper valve is a rectangular metal plate wrapped with sponge, which can slide back and forth in the groove. When the geared motor rotates forward and backward, it drives the scraper valve to move forward to close the bubble outlet and move backward to open the bubble outlet through the transverse rotating rod and the connecting rod. The first heater (31) is a nickel-chromium heating wire, fixed on the lower surface of the nozzle (16); the second heater (32) is a nickel-chromium heating wire, fixed on the upper surface of the nozzle (16); the bidirectional fan (33) is a small axial flow fan, installed in the center inside the nozzle (16), and the gas flow rate can be controlled by adjusting the rotation speed, thereby controlling the size of the flame. The gas storage tank (210) is filled with butane. The control module (41) uses a microcontroller, and the power supply (42) is a 12V battery. In addition, a first temperature measuring module (35) and a second temperature measuring module (36) are installed near the heater; the nozzle (16) is made of heat-insulating material, which forms a thermal isolation between the heater and the gas guide tube and the bubble film, ensuring that the low-temperature film breaking process is not affected by heat radiation, and ensuring the accuracy of temperature control and safety of use.

[0018] Example 2: Specific control procedures for various flame-throwing modes See Figures 7 to 10 The specific control procedures for the four flamethrower modes are as follows: (a) Mode 1: Bubbles are sprayed upwards from the first adsorption ring (151). The steps include: wetting the absorbent material → forming a bubble film with the first scraping valve → blowing bubbles and mixing smoke and combustible gas with the fan → turning off the fan after the bubbles reach the preset size → the first heater breaks the film at low temperature, the bidirectional fan exhausts air upwards, and the second heater ignites at high temperature after a preset delay to form an upward-spraying flame.

[0019] (ii) Mode 2: Symmetrical to Mode 1, bubbles are formed at the second bubble outlet by the second scraping valve, the second heater breaks the membrane, the bidirectional fan exhausts the air downwards, and the first heater ignites to form a downward-spraying flame.

[0020] (III) Mode 3: First, blow out the lower bubble. When the lower bubble reaches 70% of the preset size, stop supplying smoke and combustible gas to the lower bubble and open the scraper valve of the upper bubble at the same time. Blow out the upper and lower bubbles together. When the upper bubble reaches 30% of the preset size and the lower bubble reaches 100% of the preset size, turn off the blower and close the first and second bubble outlets at the same time. Then, the first heater breaks the membrane at low temperature, the bidirectional blower exhausts air upward, and the second heater ignites at high temperature after a preset delay, so that the flame enters the upper bubble and burns.

[0021] (iv) Mode 4: Symmetrical to Mode 3, first blow out the upper bubble. When the upper bubble reaches 70% of the preset size, stop supplying smoke and combustible gas to the upper bubble, and at the same time open the scraper valve of the lower bubble, and blow the upper and lower bubbles together. When the lower bubble reaches 30% of the preset size and the upper bubble reaches 100% of the preset size, turn off the blower and at the same time close the first and second bubble outlets. Then the second heater breaks the membrane at low temperature, the bidirectional blower exhausts the gas downward, and after a preset delay, the first heater ignites at high temperature, so that the flame enters the lower bubble and burns.

[0022] Each mode can be set to trigger once or continuously in a loop.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a first and second adsorption ring on the horizontal hollow tube, and cooperating with the independently controlled first and second scraping valves, bubbles can be formed on the upper and lower sides respectively. Combined with a bidirectional fan and a first and second heater located on both sides of the flame nozzle, four modes of flame-bubble interaction are realized, including unidirectional directional spray and flame transfer between bubbles. The visual impact is strong and the performance effect is rich.

[0025] The bidirectional fan can selectively exhaust air in either the first or the opposite second direction. Combined with the independent control of the upper and lower heaters, the direction of flame jet can be flexibly switched. The flame is confined inside the bubble or jetted in a designated direction, avoiding disorderly flame spread and improving the safety of the performance.

[0026] The operating temperature of the heater is monitored in real time by the first temperature measuring module (35) and the second temperature measuring module (36), and closed-loop control is performed by the control system to ensure that the temperature of the low-temperature membrane breaking and high-temperature ignition process is controllable. At the same time, the nozzle is made of heat insulation material to thermally isolate the heater from the combustible gas channel, prevent excessive heat accumulation, further eliminate the hidden dangers of accidental ignition and deflagration, and ensure the safe and reliable operation of the device.

[0027] The device is connected to the base, vertical hollow tube and horizontal hollow tube by adjustable hinges, which allows it to be easily switched between unfolded and folded storage states. The compact structure makes it easy to transport and store, and it is suitable for mobile performance scenarios such as stage performances and theme parks.

[0028] By placing a transparent annular component between the adsorption ring and the flame nozzle, a continuous annular adsorption surface is provided for the bubbles, allowing the audience to easily observe the formation of the bubbles and the combustion process of the flame. Simultaneously, wetting the surface of the annular component helps the bubbles adhere stably and slide, enhancing the visual effect of the performance and the reliability of the device.

Control the first heater (31) to start, generate a temperature lower than the ignition point of the combustible gas to destroy the bubble film within the range of the nozzle (16); control the bidirectional fan (33) to exhaust upward, so that the mixed gas and smoke in the lower bubble are sprayed upward from the nozzle (16); and after a preset delay, control the second heater (32) to start, generate a temperature higher than the ignition point of the combustible gas to ignite the sprayed combustible gas, so that the flame enters the upper bubble and burns.

13. A method for generating flame bubbles based on the generating device according to any one of claims 1 to 7, characterized in that, Includes the following steps: V1, control the start of the liquid pump (22) to wet the surface of each absorbent material and the transparent ring part (283); V2. Control the second scraping valve (252) to form a bubble film at the second bubble outlet (172), control the fan (28) to start and mix air, smoke and combustible gas and blow it into the second bubble outlet (172) to blow out the upper bubbles; when the upper bubbles reach 70% of the preset size, control the solenoid valve (211) of the smoke generating module (29) and the gas storage tank (210) to close; V3. Control the first scraping valve (251) to open, and blow out the lower bubble to 30% of the preset size with the assistance of the blower (28). Then turn off the blower (28) and simultaneously close the first bubble outlet (171) and the second bubble outlet (172). V4. Control the second heater (32) to start, generate a temperature lower than the ignition point of the combustible gas to destroy the bubble film within the range of the nozzle (16); control the bidirectional fan (33) to exhaust downward, so that the mixed gas and smoke in the upper bubble are sprayed downward from the nozzle (16); and after a preset delay, control the first heater (31) to start, generate a temperature higher than the ignition point of the combustible gas to ignite the sprayed combustible gas, so that the flame enters the lower bubble to burn.

14. The method according to any one of claims 10, 12, or 13, characterized in that, The flame nozzle (16) works in conjunction with the rotational speed of the bidirectional fan (33) to control the size of the flame by adjusting the amount of airflow.
