Description

Technical Field

[0001] This invention relates to the field of thin film bubble equipment technology, and more specifically, to a three-medium continuous output device for thin film bubbles and a method for generating thin film bubbles. Background Technology

[0002] Existing bubble machine patents have the following common structures.

[0003] Firstly, the innovative method utilizes the air pressure of smoke to blow up a bubble film, and uses a blowing fan to provide peeling and blowing force to the film from the outside, thereby forming a thin film bubble with three media characteristics: the dense smoke inside the film, the bubble liquid in the film itself, and the relatively pure air medium in the flow channel outside the film, which has a strong visual effect. However, in the existing solution, the bubble head does not have a stable liquid supply and maintenance scheme, and can only generate smoke bubbles for a short time (5~15 seconds) by dipping in liquid. Secondly, by adding a liquid supply pump and a liquid replenishment scraper to the bubble head to maintain and continuously replenish the bubble liquid film, it has a strong visual effect and stability, but the structure is relatively complex and prone to failure, the equipment is large in size, and the cost is high.

[0004] Thirdly, by adding smoke to a traditional continuous bubble machine, it is possible to output thin film bubbles with smoke. In this solution, the smoke is mixed with the blown air in advance, so the blown air will dilute the smoke in advance, making the smoke filling the bubble very light. At the same time, a large amount of smoke is inevitably mixed into the blown air, resulting in both the smoke bubble and the blown air being covered with smoke. The smoke bubble lacks contrast and the visual effect is not good. Summary of the Invention

[0005] To address the shortcomings of existing methods, this invention proposes a three-medium thin-film bubble continuous output device and a thin-film bubble generation method, which solves the technical problems of short operating time of thin-film bubbles and complex device structure that is prone to failure in the prior art.

[0006] In one aspect, embodiments of the present invention provide a three-medium thin-film bubble continuous output device, including a body, a driving medium module, a filling medium module, and a filling medium channel; The device body is provided with a film-forming medium tank, and the device body is provided with a first film-forming port and a second film-forming port that are respectively connected to the film-forming medium tank. The first film-forming port is connected to the filling medium module through the filling medium channel; The driving medium module is positioned relative to the second film-forming port so that the second film-forming port is located within the coverage area of ​​the driving range of the driving medium module; The second film-forming port is higher than the first film-forming port.

[0007] Optionally, the film-forming medium tank includes an upper cavity arranged vertically and a lower liquid cavity for holding the film-forming medium; The first film-forming port is connected to the lower liquid cavity, and the second film-forming port is connected to the upper cavity.

[0008] Optionally, the film-forming medium in the film-forming medium tank is a film-forming medium with a surface activity of less than 72.8 mN / m and a viscosity of more than 1 mPa·s at 20°C.

[0009] Optionally, it also includes a filling medium channel, one end of which is connected to the first film-forming port and the other end of which is connected to the filling medium module.

[0010] Optionally, it also includes an outlet tube, which is disposed at the top of the upper cavity and has one end connected to the upper cavity, and the other end is configured as the second film-forming port; The second film-forming port is configured to be higher than the top of the upper cavity.

[0011] Optionally, the outlet tube is provided with a bend section and an extension section, the bend section being connected to the upper cavity, and the second film-forming port being formed at the end of the extension section.

[0012] Optionally, the protruding section extends outward from the side of the device body away from the drive medium module.

[0013] Optionally, the bottom of the film-forming medium tank is inclined toward the first film-forming port so that the liquid in the film-forming medium tank can be collected toward the first film-forming port under the action of gravity.

[0014] Optionally, the first film-forming port is a laterally expanded slot structure.

[0015] Optionally, the filling medium module includes an air pump and an air inlet, wherein the air pump is connected to the filling medium channel through the air inlet.

[0016] Optionally, the filling medium module further includes a vaporization chamber, a heating wire, and oil-guiding cotton; One end of the vaporization chamber is a mist inlet, and the other end is a mist outlet. One end of the air inlet is connected to the mist inlet, and the other end is connected to the air pump. The oil-guiding cotton is disposed in the vaporization chamber and aligned with the air inlet. The heating wire is disposed on the oil-guiding cotton. The mist outlet is connected to the first film-forming port through a filling medium channel.

[0017] Optionally, the filling medium module includes a compressed gas tank with an internal pressure higher than the external ambient air pressure of the second film-forming port, and the compressed gas tank is connected to the first film-forming port.

[0018] Optionally, the filling medium module includes a heater, a liquid supply pump, and a heating tube; The heating tube is disposed in the heater, with one end connected to the liquid supply pump and the other end connected to the first film-forming port.

[0019] Secondly, embodiments of the present invention provide a method for generating thin-film bubbles, employing a three-medium thin-film bubble continuous output device, comprising: S1. Inject the film-forming medium into the film-forming medium tank, ensuring that the film-forming medium is higher than the first film-forming port and lower than the second film-forming port; S2, First film formation: The filling medium module is started to generate the filling medium. Under its own air pressure, the filling medium is transported to the film forming medium tank through the first film forming port. The filling medium enters the film forming medium in the film forming medium tank through the first film forming port. After contacting the film forming medium, it forms a thin film bubble that encapsulates the filling medium, thus realizing the first film formation. S3. Thin film bubble rises: Under the action of its own buoyancy, the thin film bubble moves upward and rises out of the film-forming medium surface. At this time, the liquid film rises above the liquid surface and completely covers and constrains the filling medium. S4. Thin film bubble lifting: As the filling medium is continuously input into the first film-forming port, the processes of steps S2 and S3 are continuously repeated. Thin film bubbles continuously float to the surface of the liquid and are continuously lifted towards the second film-forming port under the impetus of the gas pressure and surface tension inside the thin film bubbles. During the movement, a small amount of film-forming medium is carried on the surface of the thin film bubbles. The spherical liquid film on the surface of the thin film bubbles and the filling medium inside the thin film bubbles continuously deliver thin film bubbles to the second film-forming port to maintain the liquid film formation conditions at the second film-forming port. S5. Second film formation: When the thin film bubble is delivered to the second film formation port, under the combined action of the continuous lifting of the thin film bubble behind and the external force of the driving medium module, the thin film bubble is stretched and deformed. When the surface tension of the liquid film can no longer support it, the thin film bubble splits and flies out with the driving medium module, realizing the second film formation. During this process, the continuous lifting of the thin film bubble keeps the liquid film continuously moist and has the necessary thickness. Even if it breaks due to insufficient thickness, the subsequent liquid film will quickly fill the gap and continue to maintain the liquid film at the second film formation port, and the second film formation process is repeated continuously.

[0020] Optionally, the flow rate and concentration of the filling medium output by the filling medium module in step S2 can be adjusted to control the generation and falling speed of the thin film bubbles.

[0021] Optionally, adjusting the airflow volume and / or airflow direction of the driving medium module in step S4 controls the ejection speed of the thin film bubbles, the size and number of the thin film bubbles, and the output direction.

[0022] The so-called three-medium thin-film bubble includes a film-forming medium that constitutes the liquid film of the thin-film bubble body, a filling medium that is covered by the thin-film bubble, and an external driving medium that is isolated by the thin-film bubble. The three-medium thin-film bubble described in this patent has two completely different media, namely the filling medium and the driving medium. This is different from common thin-film bubbles, such as toy bubbles, where the inner and outer media of the thin-film bubble are the same medium, which is the wind when blowing bubbles, and there is no essential difference. Therefore, it is a two-medium thin-film bubble under the definition of this patent. The so-called three-medium thin film bubble in this patent refers to a thin film bubble whose interior and exterior are two completely different and independent media, in addition to the film-forming medium that forms the film itself. The two media can be designed and set separately. The beneficial technical effects brought about by the technical solutions provided in the embodiments of the present invention include: First, the three-medium thin-film bubble continuous output device utilizes the inherent air pressure of the filling medium as power. Through ingenious structural design, all filling media are first input into the film-forming medium through the first film-forming port, forming thin-film bubbles within the medium. Under the buoyancy of these bubbles, they rise to the liquid surface. This process continues, with newly generated thin-film bubbles constantly lifting previously generated bubbles and moving towards the second film-forming port. During this process, the thin-film bubbles generated at the first film-forming port continuously transport small amounts of film-forming and filling media to the second film-forming port, maintaining the liquid film there. Some thin-film bubbles may break, merge, or decompose during this process, but continuous replenishment ensures the second film-forming port always maintains a liquid film. Then, under the pressure of the filling medium itself, it surges into the liquid film, gradually increasing its bulge and expanding the air-receiving area. When this exceeds the surface tension of the liquid film, the thin-film bubbles split, and the resulting bubbles are further blown out by the fan. As the filling medium is continuously introduced into the film-forming medium, thin-film bubbles are continuously generated, ensuring continuous output.

[0023] Secondly, the first film formation directly provides the necessary elements for the subsequent second film formation port to generate thin film bubbles: the film-forming medium and the film-forming medium liquid film do not require separate film-forming medium replenishment and film-forming medium liquid film generation mechanisms, and the second film formation relies on the gas pressure of the filling medium itself and the driving medium. Apart from the driving medium module, no additional electrical control or liquid pump drive is required. This simplifies the structural setup, reduces the number of components, and solves the technical problem of complex structure and easy failure in the three-medium thin film bubble continuous output device.

[0024] During the research and development process, it was also discovered that if an electric drive approach were used to solve the problems of liquid replenishment and maintaining the liquid film during the continuous bubble generation process, the lifespan of electronic components such as circuits, batteries, and motors would inevitably be affected by liquid immersion. The resulting cost and waterproofing issues would severely limit the commercialization of the product. In addition, the colloidal components contained in the film-forming medium would inevitably remain on the product structure during long-term use, posing an unavoidable risk of failure to the motor and transmission components. This invention utilizes the properties of the filling medium, the film-forming medium, and the thin film bubbles themselves, and comprehensively utilizes physical principles such as gravity, buoyancy, fluid mechanics, and surface tension to achieve the continuous generation and output of thin film bubbles using an innovative method. This allows the entire device to achieve its functional purpose with a purely physical structure without electric drive, completely avoiding the risks of immersion, mechanical adhesion, and pipeline blockage caused by liquid immersion and residual contamination of the film-forming medium. At the same time, it allows for immersion washing and cleaning, and can be manufactured at a cost far lower than that of electric drive solutions, presenting significant advantages.

[0031] The present invention provides a three-medium thin-film bubble continuous output device, which aims to solve the above-mentioned technical problems of the prior art.

[0032] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0033] This invention provides a three-medium thin-film bubble continuous output device, the structural schematic of which is shown below. Figure 1 As shown, it includes: The device includes a body 10, a driving medium module 20, and a filling medium module 30. The body 10 is provided with a film-forming medium tank 101, and the body 10 is provided with a first film-forming port 10101 and a second film-forming port 10102 that are respectively connected to the film-forming medium tank 101. The first film-forming port 10101 is configured to be connected to the filling medium module 30, and the driving medium module 20 is configured such that the second film-forming port 10102 is located within the coverage area of ​​the driving range of the driving medium module 20.

[0034] Preferably, to prevent the film-forming medium from overflowing from the second film-forming port 10102, with the bottom surface of the device body 10 as a reference, the height of the second film-forming port 10102 is higher than that of the first film-forming port 10101.

[0035] As can be seen from the above, the film-forming medium tank 101 is used to inject the film-forming medium.

[0036] In this embodiment, the inherent air pressure of the filling medium is used as a driving force. All the filling medium is first input into the film-forming medium through the first film-forming port 10101, forming thin film bubbles in the film-forming medium. Under the buoyancy of the bubbles, they rise to the surface of the film-forming medium. During this continuous cycle, newly generated thin film bubbles are constantly produced, continuously lifting the previously generated thin film bubbles and moving them towards the second film-forming port 10102. In this process, the thin film bubbles generated at the first film-forming port 10101 continuously transport small amounts of film-forming medium and filling medium to the second film-forming port 10102, and can maintain the liquid film at the second film-forming port 10102. During this process, some thin film bubbles will rupture, merge, and decompose, but they can be continuously replenished to ensure that the second film-forming port 10102 always maintains a liquid film state. Furthermore, under the pressure of the filling medium itself, after the thin film bubbles reach the second film-forming port 10102, the pressure generated by the input of the filling medium and transmitted through the continuously generated thin film bubbles, combined with the wind pressure of the driving medium module 20, will peel off the thin film bubbles from the liquid film stretched at the second film-forming port 10102. More specifically, during the stretching process of the second film-forming port 10102, the filling medium rushes into the liquid film to make it bulge, thereby completing the blowing out of the driving medium module 20.

[0037] As described above, this embodiment directly introduces the filling medium into the film-forming medium. Utilizing the immiscibility of the film-forming medium and the filling medium, thin film bubbles are formed inside the film-forming medium. By utilizing the surface tension and viscosity characteristics of the film-forming medium itself, the bubbles are maintained and move towards the area covered by the driving medium under pressure and the constraint of the bubble liquid tank until they reach the area covered by the driving medium, where they split and are blown out, thus completing the generation of three-medium bubbles. The difference between this and existing structures is that it does not require frequent dipping of the film-forming medium, does not require setting up two separate channels for independent transportation of the film-forming medium and the filling medium, and does not require a mechanical structure to convert the film-forming medium into a liquid film. This ensures the continuous generation of thin film bubbles and simplifies the overall structure of the three-medium thin film bubble continuous output device. In addition, the filling medium is completely covered by the liquid film and eventually forms thin film bubbles, so the filling medium will not overflow from the second film-forming port 10102.

[0038] More specifically, the driving medium module 20 is used to provide airflow, and the outlet direction of the driving medium module 20 is set to be consistent with the outlet direction of the thin film bubbles from the second film forming port 10102.

[0039] Alternatively, the drive medium module 20 can be a fan.

[0040] Optionally, the film-forming medium tank 101 includes an upper cavity 1012 arranged vertically and a lower liquid cavity 1011 for holding the film-forming medium; the first film-forming port 10101 is connected to the lower liquid cavity 1011, and the second film-forming port 10102 is connected to the upper cavity 1012.

[0041] The second film-forming port 10102 can be connected to the side wall or top surface of the upper cavity 1012. Preferably, the second film-forming port 10102 is connected to the top surface of the upper cavity 1012.

[0042] In this embodiment, the upper cavity 1012 and the lower liquid cavity 1011 of the film-forming medium tank 101 are distributed vertically. Specifically, the lower liquid cavity 1011 is used to hold the injected film-forming medium. Thus, the second film-forming port 10102 is always higher than the upper liquid surface of the film-forming medium surface. In conjunction with the above, the thin film bubbles formed in the lower liquid cavity 1011 rise to the upper cavity 1012 and are then output to the second film-forming port 10102. The upper cavity 1012 can serve as an accumulation space for the thin film bubbles and the filling medium, thereby ensuring that there are enough thin film bubbles to replenish the second film-forming port 10102. This achieves the aforementioned goal of continuously delivering a small amount of film-forming medium and filling medium to the second film-forming port 10102 and maintaining the liquid film at the second film-forming port 10102, ensuring that the second film-forming port 10102 always maintains a liquid film state.

[0043] In order to make full use of the capacity of the film-forming medium tank 101 and to extend the working time after each liquid addition, the first film-forming port 10101 is preferably located at the bottom of the side wall of the lower liquid chamber 1011. The liquid level gradually decreases until the liquid level can no longer cover the first film-forming port 10101, so that the conditions required for the first film formation cannot be met.

[0044] Other points to note are that the upper cavity 1012 and lower liquid cavity 1011 in the film-forming medium tank 101 are virtual representations for ease of understanding of the structure and function. In reality, there is no specific structure or interface to distinguish them. Specifically, it can be understood that in the normal working posture and state of the structure, the area where the film-forming medium is located is the lower liquid cavity 1011, and the remaining space is the upper cavity 1012, with the film-forming medium surface as the boundary. It is particularly important to note that the above concepts are used for distinction because the film-forming medium level is dynamically changing. For example, as the device is used, the film-forming medium is continuously consumed, and the liquid level will gradually decrease; also, the liquid level will change with changes in posture. Under the above conditions, there may be a scenario where the first film-forming port leaks liquid and fails to meet the working conditions. Therefore, the so-called upper cavity 1012 and lower liquid cavity 1011 should be accurately defined as follows: when the device is in at least one posture and a certain volume of film-forming medium is added, the film-forming medium level can simultaneously completely cover the first film-forming port 10101 without contacting the second film-forming port 10102. In this state, the upper region of the film-forming medium surface is the upper cavity 1012 and the lower liquid region is the lower liquid cavity 1011.

[0045] Any structure that meets the above definition is within the scope of protection. Regardless of whether the liquid level completely covers the first film-forming port 10101 in a specific posture or state, as long as it can completely cover the first film-forming port 10101 at a certain liquid level and at a certain posture angle without contacting the second film-forming port, the upper region of the film-forming medium surface in this state is the upper cavity 1012 and the lower liquid region is the lower liquid cavity 1011, all of which are within the scope of protection of this patent.

[0046] Optionally, the film-forming medium in the film-forming medium tank 101 is a film-forming medium with a surface activity of less than 72.8 mN / m and a viscosity of more than 1 mPa·s at 20°C.

[0047] The film-forming medium is a liquid with low surface activity and a certain viscosity. For example, the film-forming medium can be a bubble liquid, a foaming agent, egg white, or a fire extinguishing agent.

[0048] Optionally, such as Figure 1 and Figure 2As shown, it also includes a filling medium channel 40, one end of which is connected to the first film-forming port 10101, and the other end is used to connect to the filling medium module 30.

[0049] The filling medium channel 40 can be exemplified as an inlet tube used to connect the filling medium module 30 and the first film-forming port 10101. In summary, the filling medium channel 40 is preferably disposed close to the outer wall of the device body 10 where the first film-forming port 10101 is opened, thus achieving a tight assembly between the filling medium channel 40 and the film-forming medium tank 101, thereby realizing the miniaturization of the three-medium thin film bubble continuous output device.

[0050] More specifically, the filling medium channel 40 is arranged along the height direction of the film-forming medium tank 101. The lower end of the filling medium channel 40 is connected to the first film-forming port 10101, and the upper end is at least equal to or higher than the upper top surface of the lower liquid chamber 1011. In this way, when the film-forming medium in the lower liquid chamber 1011 is not working, the filling medium will not overflow outward through the upper end of the filling medium channel 40.

[0051] Optionally, it also includes an outlet tube 50, which is disposed at the top of the upper cavity 1012 and has one end connected to the upper cavity, and the other end is configured as a second film-forming port 10102; the second film-forming port 10102 is configured to be higher than the top of the upper cavity 1012.

[0052] The outlet tube 50 is disposed at the top of the upper cavity 1012, and the top end of the outlet tube 50 forms a second film-forming port 10102. For example, the second film-forming port 10102 is ultimately set to be oblique or horizontal. At the same time, the orientation of the second film-forming port 10102 can be set as needed, and will not be limited here.

[0053] Optionally, the outlet tube 50 is provided with a bend section 51 and an extension section 52, the bend section 51 is connected to the upper cavity 1012, and the second film-forming port 10102 is formed at the end of the extension section 52.

[0054] For example, the driving medium module 20 is located on one side of the body 10, the turning section 51 is arranged perpendicular to the top of the upper cavity 1012, and the protruding section 52 extends in a direction away from the driving medium module 20. Specifically, the second film-forming port 10102 is located at the end of the protruding section 52 away from the turning section 51.

[0055] The angle between the axes of the extended turning section 51 and the extending section 52 is between 30° and 135°, preferably 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130° or 135°.

[0056] Optionally, the extension 52 extends outward on the side of the body 10 away from the drive medium module 20.

[0057] It is understandable that when the blown film bubbles are not powerful enough, a small number of droplets, foam or smoke bubbles may drip and stick at the port of the extension section 52, which will prevent the film bubbles from flying out and cause them to accumulate. At this time, the port of the extension section 52 is far away from the outer wall of the film forming medium tank 101. Before the bubbles fall and drip and stick, they fly out under the action of the wind generated by the driving medium module, which can prevent the droplets from dripping directly onto the outer wall of the film forming medium tank 101.

[0058] More preferably, the protruding section 52 extends outward in the direction away from the driving medium module 20 of the device body 10 to a position outside the outer wall of the film-forming medium tank 101. At this time, the port of the protruding section 52 extends outside the outer wall of the film-forming medium tank 101, and the droplets will not drip onto the outer wall of the film-forming medium tank 101, thus avoiding adhesion to the outer wall of the film-forming medium tank 101.

[0059] Optionally, the bottom of the film-forming medium tank 101 is inclined toward the first film-forming port 10101 so that the liquid in the film-forming medium tank 101 can be collected toward the first film-forming port 10101 under the action of gravity.

[0060] In this embodiment, the bottom of the film-forming medium tank 101 is inclined toward the first film-forming port 10101. As a result, the film-forming medium in the film-forming medium tank 101 concentrates toward the first film-forming port 10101 under the action of gravity. As the film-forming medium is continuously consumed, the remaining film-forming medium can continue to concentrate toward the first film-forming port 10101 to fill the first film-forming port 10101, ensuring full contact between the filling medium and the film-forming medium.

[0061] The inclined arrangement of the bottom of the film-forming medium tank 101 toward the first film-forming port 10101 can take two forms: First, the film-forming medium tank 101 is horizontal, but its entire structure is inclined toward the first film-forming port 10101, thus demonstrating the inclination of the bottom of the film-forming medium tank 101 toward the first film-forming port 10101. Second, the bottom of the film-forming medium tank 101 is set as an inclined surface toward the first film-forming port 10101, and the inclined surface automatically gathers the film-forming medium in the film-forming medium tank 101 toward the first film-forming port 10101.

[0062] Optionally, the first film-forming port 10101 is a laterally unfolded slot structure.

[0063] As can be seen from the foregoing, the first film-forming port 10101 is preferably located at the bottom of the side of the lower liquid chamber 1011. At this time, the first film-forming port 10101 needs to be completely immersed in the film-forming medium in order to perform a stable function. When the liquid level is too low to completely immerse the first film-forming port 10101, the generation of thin film bubbles will become unstable. The horizontally expanded slot structure is conducive to improving the utilization efficiency of the film-forming medium, reducing the minimum working liquid level of the bubble generation device, and thus improving the working endurance and stability.

[0064] Other slot structures are generally rectangular or inverted trapezoidal openings with right angles, chamfers, or rounded corners.

[0068] In this embodiment, the filling medium module 30 is mainly used as a handheld smoke machine. The oil-guiding cotton 36 introduces e-liquid from the outside. The heating wire 35 is equipped with a battery to generate heat. The heating wire 35 heats the e-liquid on the oil-guiding cotton 36.

The liquid flows through the heating tube 33 and passes through the heater 31 to form heating and pressurization. After the high temperature and high pressure atomized liquid is sprayed out of the atmosphere, it is rapidly depressurized, expanded, and cooled, and atomized to form smoke. The smoke finally passes through the first film-forming port 10101.

[0075] To facilitate understanding of the thin-film bubble formation process, based on the same inventive concept, this invention provides a method for generating thin-film bubbles using the aforementioned three-medium thin-film bubble continuous output device, comprising: S1. Inject film-forming medium into film-forming medium tank 101, and ensure that the film-forming medium is higher than the first film-forming port 10101 and lower than the second film-forming port 10102. S2, First film formation: The filling medium module 30 is started to generate the filling medium. Under its own air pressure, the filling medium is transported to the film forming medium tank 101 through the first film forming port 10101. The filling medium enters the film forming medium in the film forming medium tank 101 through the first film forming port 10101. After contacting the film forming medium, it forms a thin film bubble that encapsulates the filling medium, thus realizing the first film formation. S3. Thin film bubble rises: Under the action of its own buoyancy, the thin film bubble moves upward and rises out of the film-forming medium surface. At this time, the liquid film rises above the liquid surface and completely covers and constrains the filling medium. S4. Thin film bubble lifting: As the filling medium is continuously input into the first film-forming port 10101, the processes of steps S2 and S3 are continuously repeated. Thin film bubbles continuously float to the surface of the liquid and are continuously lifted towards the second film-forming port 10102 by the gas pressure and surface tension inside the thin film bubbles. During the movement, a small amount of film-forming medium is carried on the surface of the thin film bubbles. The spherical liquid film on the surface of the thin film bubbles and the filling medium inside the thin film bubbles continuously deliver thin film bubbles to the second film-forming port 10102 to maintain the liquid film formation conditions at the second film-forming port 10102. S5. Second film formation: When the thin film bubble is delivered to the second film formation port 10102, under the combined action of the continuous lifting of the thin film bubble behind and the external force of the driving medium module 20, the thin film bubble is stretched and deformed. When the surface tension of the liquid film can no longer support it, the thin film bubble splits and flies out with the driving medium module 20, realizing the second film formation. During this process, the continuous lifting of the thin film bubble keeps the liquid film continuously moist and has the necessary thickness. Even if it breaks due to insufficient thickness, the subsequent liquid film will quickly fill the gap and continue to maintain the liquid film at the second film formation port 10102, and the second film formation process is repeated continuously.

[0076] This method describes the actual working process of the aforementioned three-medium thin film bubble continuous output device. The film-forming medium tank 101 is filled with film-forming medium, and the filling medium module 30 introduces filling medium into the film-forming medium tank 101 through the first film-forming port 10101.

[0077] Specifically, the film-forming medium tank 101 includes an upper cavity 1012 arranged vertically and a lower liquid cavity 1011 for holding the film-forming medium. It is clear that the first film-forming port 10101 is lower than the second film-forming port 10102 in the height direction of the film-forming medium tank 101. Further, if a filling medium channel 40 and an outlet pipe 50 are provided, the filling medium module 30 introduces the filling medium into the first film-forming port 10101 through the filling medium channel 40, and thin film bubbles are formed and discharged from the second film-forming port 10102 of the outlet pipe 50 under the action of the driving medium module 20.

[0078] The key point to note is that the first film formation in step S2 can be understood as follows: the filling medium module 30 is activated to generate the filling medium. Under its own air pressure, the filling medium is transported through the filling medium channel 40 to the lower liquid tank area (i.e., the lower liquid cavity 1011) of the film forming medium tank 101. The film forming medium tank 101 is filled with the film forming medium. The area where the film forming medium is located is the lower liquid tank area, and the upper cavity 1012 area above the surface of the film forming medium is the upper liquid tank area.

[0079] The filling medium enters the film-forming medium in the lower zone of the liquid tank through the first film-forming port 10101 at the outlet of the filling medium channel 40. After the filling medium comes into contact with the film-forming medium, it forms a thin film bubble that encapsulates the filling medium, thus completing the first film formation. The core of the first film formation is to utilize the encapsulation effect of the film-forming medium on the filling medium to form a stable thin film bubble structure, providing the filling medium and film-forming medium carrier for the second film formation.

[0080] In addition, in step S3, the thin film bubble moves upward under its own buoyancy, rising from the lower region of the liquid tank to the upper region of the liquid tank. During the movement, the surface of the thin film bubble carries a small amount of film-forming medium, continuously supplying film-forming medium and filling medium to the second film-forming port 10102 opening on the upper wall of the upper region of the liquid tank, maintaining the liquid film formation conditions at the second film-forming port.

[0081] Thin film bubbles are formed only after the above-mentioned important steps. All steps are completed in the main flow path with the film-forming medium tank 101 as the main flow path. There are no branches. The filling medium and the film-forming medium path are kept in contact. There are no external pumps to reinforce the connection, which reflects the aforementioned simple structure and continuous bubble generation effect.

[0082] Optionally, the flow rate and concentration of the filling medium output by the filling medium module 30 in step S2 can be adjusted to control the generation and falling speed of the thin film bubbles.

[0083] Generally, the faster the flow rate of the filling medium, the faster the rate of thin film bubble formation at the second film-forming port 10102 per unit time, the higher the concentration of the filling medium, and the greater the weight of the filling medium introduced into the thin film bubble per unit volume, thus resulting in a faster falling speed; Optionally, adjusting the airflow volume and / or airflow direction of the driving medium module 20 in step S4 controls the flight speed of the thin film bubbles, the size and number of the thin film bubbles, and the output direction.

[0084] It can be understood that the airflow angle of the driving medium module 20 can change the outflow direction of the thin film bubbles, which will not be elaborated here.

[0085] To illustrate the definition of a medium, the following are some examples of media: Firstly, the filling medium module 30 can be a vaporization chamber 34, a heating wire 35, an oil-guiding cotton 36, and an air pump 38; or the filling medium module 30 can be a heater 31, a liquid supply pump 32, and a heating tube 33. The driving medium module 20 is a fan, and the film-forming medium is bubble solution. In this case, the filling medium generated by the filling medium module 30 is aerosol smoke, and the corresponding thin film bubbles are smoke bubbles. This application is for the aforementioned handheld smoke machine smoke source / stage smoke machine smoke.

[0086] Secondly, the filling medium module 30 is a compressed gas tank, the driving medium module 20 is a fan, and the film-forming medium is bubble solution. In this case, the filling medium generated by the filling medium module 30 is a pure gas; specifically, gases such as hydrogen and helium can generate floating air bubbles. Combustible gases such as hydrogen and butane can form flame bubbles. Interestingly, unlike the aforementioned gases, the faster the flow rate of these lightweight gases, the higher the concentration of the filling medium, and the greater the weight of the filling medium introduced into the thin-film bubble per unit volume. However, due to the characteristics of lightweight gases, the greater the buoyancy of the thin-film bubble, the slower its falling speed.

[0087] Thirdly: the filling medium module 30 is a compressed gas tank, the driving medium module 20 is compressed air, the film-forming medium is the extinguishing agent, and the compressed gas tank outputs air to form extinguishing foam. This application can be applied to split-type fire extinguishers.

[0088] Fourthly: the filling medium module 30 is a compressed air tank, the driving medium module 20 is a fan, the film-forming medium is a foaming agent, and the compressed air tank outputs air to form thin spherical bubbles.
