Description

Technical Field

[0001] This invention belongs to the field of bubble toy technology, and more specifically, relates to a large, retractable, portable, electrically driven bubble rod capable of automatically forming a film without the need for bubble solution, and a method for forming the film therewith. Background Technology

[0002] In the entertainment and toy industries, bubbles serve as a unique entertainment element, possessing strong fun and visual appeal. Traditional bubble toys typically require immersing the entire film-forming ring in bubble solution. After the ring is removed from the solution and a bubble film has formed on it, it is swung to create bubbles. This operation is relatively convenient for small film-forming tools. However, when it is necessary to create giant bubbles, bubbles large enough to wrap around a person, or continuous bubble production, the traditional dipping method has the following problems.

[0003] Large bubble solution containers are required, taking up a lot of space and making them inconvenient to carry and move. These large containers are not only bulky but also require fixed storage locations, preventing them from being moved by the user and severely limiting the usability of bubble toys.

[0004] Each time a bubble film is formed and the bubble wand is swung, the bubble film breaks and cannot automatically regenerate, requiring repeated dipping and making continuous play impossible. In scenarios requiring continuous bubble production (such as stage performances or children's parties), users need to frequently immerse the film-forming ring in the bubble solution, which is cumbersome, inefficient, and severely impacts the entertainment experience.

[0005] Due to the location limitations of the bubble solution container, the bubble stick must be used near it, reducing its entertainment value and interactivity. Users cannot automatically generate bubble film while moving, thus failing to achieve the free experience of playing while walking.

[0006] While some electric bubble guns have emerged on the market that can continuously produce a large number of small bubbles, their film-forming ring diameter is usually small (generally less than 10 cm), making it impossible to produce giant bubbles large enough to encircle a person. Large-diameter bubble film-forming tools (such as giant bubble rings used in stage performances) can produce larger bubbles, but their film-forming method still relies on immersing the entire bubble ring in a specially designed large liquid pool, which is complex to operate, inconvenient to carry, and cannot form a film automatically.

[0007] Therefore, developing a bubble wand that is portable, can generate huge bubbles (even big enough to trap people), can automatically form a film, and can be played with while moving around has significant market value. Summary of the Invention

[0008] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a large-scale bubble rod with electrically driven film-forming mechanism and its film-forming method. By configuring a support rod, bubble ring assembly, liquid supply system, liquid guide tube, and film-forming system, and controlling the moving part to drive the film-forming component to move along the bubble ring assembly at least once, the film-forming component scrapes against the absorbent material surface of the liquid guide tube on the bubble ring assembly, thereby forming a closed bubble film within the annular structure. This invention solves the problems of large bubble rods being inconvenient to carry, unable to automatically form a film, and requiring repeated dipping in bubble solution in existing technologies. It achieves various retractable structures for the bubble ring assembly (segmented splicing, flexible winding, inflatable type), facilitating transportation and storage. Through wired or wireless drive and multiple working modes (single, continuous, individual liquid supply, alternating forward and reverse rotation), it achieves automated and continuous film formation, reducing operational difficulty and making it suitable for users of different ages.

[0009] To achieve the above objectives, one aspect of the present invention provides a large bubble bar for electrically driven film formation, comprising a support rod (1), a bubble ring assembly (2) connected to one end of the support rod (1), a liquid supply system (3), a liquid guide tube (4), a film formation system (5), and a control unit (6); wherein the bubble ring assembly (2) has a closed annular structure; the liquid supply system (3) is used to supply bubble liquid to the vicinity of the annular structure; the liquid guide tube (4) is detachably fixed to the bubble ring assembly (2) and arranged along the annular structure for conveying bubble liquid; the film formation system (5) includes: a moving part (51) movable along the annular structure, and a control unit (6) connected to the moving part (51). 1) The associated film-forming element (52) and the drive unit (53) that drives the moving part (51); the control unit (6) is electrically connected to the liquid supply system (3) and the drive unit (53) and is configured to: during the movement of the moving part (51) along the annular structure of the bubble ring assembly (2) for at least one revolution, cause the film-forming element (52) to scrape the surface of the absorbent material (43) on the annular structure of the bubble ring assembly (2) to generate a bubble film between the film-forming element (52) and a portion of the arc of the annular structure of the bubble ring assembly (2), and when the moving part (51) completes one revolution, form a closed bubble film in the annular structure of the bubble ring assembly (2).

[0010] Furthermore, the connection between the moving part (51) and the support rod (1) can be wired or wireless. When wired, the support rod (1) supplies power to the moving part (51) and transmits control signals through a wire, and the support rod (1) is provided with an automatic wire retraction module (54) for retracting the wire. When wireless, the moving part (51) has a built-in rechargeable battery, and the control unit (6) on the support rod (1) transmits control signals to the moving part (51) wirelessly.

[0011] Furthermore, the film-forming component (52) obtains bubble liquid by immersing itself in the absorbent material (544) within the automatic take-up module (54) as its main liquid supply source; and / or, the film-forming component (52) obtains bubble liquid by scraping the surface of the absorbent material (43) on the bubble ring assembly (2) as an auxiliary liquid supply and film-forming method.

[0012] Furthermore, the bubble ring assembly (2) is a detachable multi-arc segment splicing structure, an integrated flexible rollable structure, or an inflatable structure. When the bubble ring assembly (2) is a multi-arc segment splicing structure, each arc segment has a protruding plug (26) at one end and a recessed socket (27) at the other end. The multiple arc segments are connected in series by elastic ropes (21) and non-elastic ropes (22). The elastic ropes (21) are used to assist in assembly, and the non-elastic ropes (22) are used for tensioning and fixing.

[0013] Furthermore, the motion unit (51) moves along the annular structure by moving along the guide rail (28). The control unit (6) is configured to have one or more of the following operating modes: single film formation mode, continuous film formation mode, and individual liquid supply mode; and / or, the control unit (6) is configured to drive the motion unit (51) to rotate clockwise once and then counterclockwise once along the annular structure, alternating between the two.

[0014] Furthermore, the bubble ring assembly (2) and the support rod (1) are connected by a detachable connection structure, which includes one or more of a snap-fit ​​(11) structure, a threaded connection structure, or a pin structure. The liquid guide tube (4) and the bubble ring assembly (2) are connected by a detachable fixing structure; the detachable fixing structure is one or more of a magnetic structure, a Velcro structure, a slot structure, a strap structure, or a snap fastener structure. Preferably, the detachable fixing structure is a magnetic structure, including a first magnetic element (41) disposed on the bubble ring assembly (2) and a second magnetic element (42) disposed on the liquid guide tube (4), wherein the first magnetic element (41) and the second magnetic element (42) have opposite polarities and attract each other.

[0015] Furthermore, when storing the bubble ring, if the bubble ring is a multi-segment spliced ​​structure, remove the liquid guide tube (4) installed on the bubble ring assembly (2) and roll it up for storage. Loosen the adjusting bolt, disassemble and fold the bubble ring assembly (2), remove the moving part (51), and let the film-forming part (52) be completely stored in the automatic winding module (54). Disconnect the bubble ring assembly (2) from the support rod (1), and then disassemble the support rod (1). Disassemble the bubble ring into small parts and put them into boxes or bags with relatively small length, width, and height for easy carrying and transportation. If the bubble ring assembly (2) is a flexible structure, remove the moving part (51) from the bubble ring, disconnect the liquid guide tube (4) on the bubble ring assembly (2) from the liquid supply system (3), and store the flexible bubble ring and... The liquid guide tube is wound up and stored together. The connection between the flexible bubble ring assembly (2) and the support rod (1) is removed. The support rod (1) is then disassembled, and the bubble rod is disassembled into small parts. These parts are placed in boxes or bags with relatively small length, width, and height for easy carrying and transportation. When the bubble ring assembly (2) is an inflatable structure, the moving part (51) is removed from the bubble ring. The connection between the liquid guide tube (4) and the liquid supply system (3) on the bubble ring assembly (2) is removed. The bubble ring of the inflatable structure is vented. The vented bubble ring and the liquid guide tube are then wound up and stored together. The connection between the inflatable bubble ring assembly (2) and the support rod (1) is removed. The support rod (1) is then disassembled, and the bubble rod is disassembled into small parts. These parts are placed in boxes or bags with relatively small length, width, and height for easy carrying and transportation.

[0016] Another aspect of the present invention provides a film-forming method based on the above-mentioned bubble rod, comprising the following steps: placing the bubble ring assembly (2) in a working state; activating the liquid supply system (3) to keep the film-forming component (52) and the absorbent material (43) on the annular structure moist; driving the moving part (51) to move at least one revolution along the annular structure, during which the film-forming component (52) scrapes the surface of the absorbent material (43) on the annular structure to form a closed bubble film; and waving the support rod (1) to blow air onto the bubble film to generate bubbles.

[0017] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: (1) The present invention provides a large bubble rod for electric winding film formation and its film formation method. By setting up a liquid supply system and a film formation system, and under the control of the control unit, the moving part drives the film forming part to move along the annular structure of the bubble ring assembly for at least one revolution. The film forming part scrapes the surface of the absorbent material, thereby forming a closed bubble film in the annular structure. This realizes automation and one-click film formation, eliminating the need for users to repeatedly dip the bubble liquid, and significantly improving the convenience and entertainment of use.

[0018] (2) The present invention provides a large bubble rod for electric winding film formation and its film formation method. The bubble ring assembly can adopt a detachable segmented splicing, integrated flexible rollable or inflatable structure, which greatly reduces the volume after storage, making it easy to carry and transport, and solving the problem of the inconvenience of carrying large bubble rings. At the same time, the liquid guide tube and the bubble ring assembly adopt a detachable fixing structure (magnetic, Velcro, card slot, strap or snap), which facilitates quick installation and disassembly, further improving portability.

[0019] (3) The present invention provides a large bubble rod for electric winding film formation and its film formation method. The connection between the moving part and the support rod can be wired or wireless. When wired, an automatic wire winding module is set to avoid wire tangling. When wireless, a built-in rechargeable battery is provided to adapt to different usage scenarios. The control unit provides multiple working modes such as single film formation, continuous film formation, individual liquid supply and alternating forward and reverse rotation. Users can flexibly select according to their needs. It is suitable for single-person precise encasing operation and also suitable for continuous bubble performance in a fixed position.

[0020] (4) The present invention provides a large bubble rod for electric winding film formation and its film formation method. The main liquid supply source for the film forming component is the second liquid guide tube in the automatic winding module, which ensures that the film forming component remains moist during the movement. At the same time, the water-absorbing material on the bubble ring assembly provides auxiliary liquid supply and scrapes the film forming interface, thus ensuring the success rate and stability of film formation.

[0021] (5) The electric winding film forming large bubble rod and its film forming method of the present invention can adapt to various size requirements: from 30 cm handheld model to over 80 cm loop model, all can achieve stable film forming, and the bubble ring and support rod, and the liquid guide tube and bubble ring adopt standardized detachable connection structure, which reduces manufacturing cost and improves the product's versatility and market adaptability.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, when an element is referred to as "fixed to," "set on," or "provided on" another element, it can be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to or indirectly connected to the other element. The terms "mounted," "connected," "linked," and "provided with" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Example 1: Wired drive + scraping film formation + segmented splicing bubble ring (composite tensioning system) like Figure 1 and Figure 2 As shown, this embodiment provides a wired-driven large bubble bar, whose bubble ring assembly adopts a detachable segmented splicing structure and a composite tensioning system.

[0027] The bubble ring assembly (2) is composed of multiple arc-shaped segments connected end to end. Taking 11 segments as an example, each arc-shaped segment has a protruding plug (26) at one end and a recessed socket (27) at the other end, and adjacent arc-shaped segments are connected by plugging.

[0028] Composite tensioning structure: To balance assembly convenience and structural strength, this embodiment employs a composite tensioning system combining an elastic rope (21) and a non-elastic rope (22). Specifically: The first to tenth arc-shaped segments are connected in series by an elastic rope (21), such as a rubber band or elastic cord. This elastic rope (21) always maintains a contraction trend, applying inward pre-pressure to the first to tenth arc-shaped segments. Under this pre-pressure, the first to tenth segments can be pre-assembled into a single section and then connected to the two ends of the eleventh arc-shaped segment to achieve rapid pre-assembly. The first to tenth arc-shaped segments are also connected in series by a non-elastic rope (22), such as a nylon rope or steel wire rope. The two ends of the non-elastic rope (22) are provided with rope loops. The two ends of the eleventh arc-shaped segment are provided with tension adjustment bolts (23) and inner thread sleeves (24). The bolts (23) are provided with hooks (25) that do not rotate with the bolts.

[0029] Installation method: Insert the protruding plug (26) of the first arc segment of the pre-assembled arc into the recessed socket (27) of the eleventh arc segment, and insert the protruding plug (26) of the eleventh arc segment into the recessed socket (27) of the tenth arc segment of the pre-assembled arc. During this process, the elastic rope (21) automatically pulls the segments together to assist in positioning. Then, loop the loop of the non-elastic rope (22) extending from the protruding end of the first arc segment onto the hook (25) of the adjusting bolt at the protruding end of the eleventh arc segment, and loop the loop of the rope extending from the recessed end of the tenth arc segment onto the hook (25) of the adjusting bolt at the recessed end of the eleventh arc segment. Adjust the bolts (23) at both ends outward to increase the length of the adjusting bolt (23) extending from the inner thread sleeve (24), thereby tightening the non-elastic rope and firmly splicing all the arc segments into a complete ring. At this point, the non-elastic cord (22) provides the main tension, ensuring that the bubble ring does not deform or fall apart when swung; the elastic cord (21) provides auxiliary preload, but does not bear the main tension function.

[0030] Other tensioning methods: Those skilled in the art should understand that the above-described "non-elastic rope + adjusting bolt" is merely an example. Any structure capable of connecting the various arc segments in series and adjusting the tension is an equivalent substitution of this invention. For example, a metal chain with a ratchet tensioner can be used: after the first ten segments of the chain are connected in series, one end is fixed to one end of the eleventh segment, and the other end passes through the ratchet tensioner. The chain is tightened by turning the handle, and the pawl prevents reverse rotation. Alternatively, a fiber belt with a cam clamping mechanism can be used: after the first ten segments are connected in series, the fiber belt passes through the cam clamping block, and rotating the cam handle can tighten or loosen the chain. These alternative methods all fall within the protection scope of this invention.

[0031] Connection with the support rod: A connection interface (13) is provided on the outer side of the middle part of the eleventh arc segment, and a detachable connection structure that mates with the connection interface is provided at the top of the support rod (1). The detachable connection structure can be one or more of a snap-fit ​​(11), a thread (15), or a pin structure. After the bubble ring assembly is assembled, the connection interface (13) is connected to the corresponding structure at the top of the support rod (1) and locked, so that the bubble ring assembly can be detachably fixed to the support rod.

[0032] Liquid supply system: Located inside the support rod (1), it includes a liquid storage tank (31), a liquid transfer pump (32), a power supply (33), and a liquid guide pipe (4). Part of the liquid guide pipe is arranged along the annular frame of the bubble ring assembly. Multiple micropores are opened on its pipe wall, and its outer surface is covered with absorbent material. The liquid guide pipe (4) is connected to the liquid pump (32) in the liquid supply system. The bubble liquid seeps out through the micropores and wets the absorbent material.

[0033] Film-forming system: The guide rail (28) is set on the outer side of the front of the bubble ring assembly (2). When the arc segments are spliced ​​together, the guide rail segments on each segment together form a continuous ring track (28). The moving part (51) (e.g., a trolley) is mounted on the guide rail (28) and can move bidirectionally along the track.

[0034] Drive method of the moving part: In this embodiment, the moving part (51) is driven by a miniature DC motor. The output shaft of the motor is connected to a reduction gear set, which drives the wheel of the moving part, causing the moving part to move along the guide rail (28). The speed of the moving part can be achieved by adjusting the PWM duty cycle through the control unit. Those skilled in the art should understand that the above driving method is only an example, and the moving part can also be implemented by other methods such as stepper motor, servo motor or electromagnetic drive. As long as it can move along the ring structure, it is applicable to the present invention.

[0035] The moving part is equipped with a conductive slip ring (55). One end of the drive wire is connected to the motor (53) of the moving part through the conductive slip ring, and the other end is connected to the control unit (6) and the power supply (33). The drive wire passes through the automatic winding module (54), which is equipped with a spring winding mechanism (542) that can automatically release or retract the drive wire with the movement of the moving part to avoid the wire from getting tangled. The automatic winding module can also adopt a motor-driven active winding mechanism or a spring-loaded winding device, which are known alternatives in the prior art.

[0036] The automatic take-up module (54) also has a second liquid guide tube (541) with an independent circuit inside. The surface of the liquid guide tube has micropores. After being connected to the liquid supply system, the bubble liquid can penetrate into the absorbent material (544) inside the automatic take-up module (54) and wet the absorbent material on the surface of the drive wire (52) that passes through it. This is the main way for the drive wire (i.e., the film-forming element 52) ​​to obtain bubble liquid, ensuring that the drive wire remains wet during the movement.

[0037] Film-forming component: The film-forming component (52) is the drive wire itself, and its surface is covered with a flexible absorbent material. When the moving part (51) moves along the guide rail (28), the film-forming component (52) slides over the absorbent material (43) on the surface of the liquid guide tube (4) inside the bubble ring, forming a scraping. The linear film-forming component (52) slides over a portion of the absorbent material (43) on the surface of the liquid guide tube on the circular bubble ring assembly (2), and a bubble film is generated between the film-forming component (52) and a portion of the arc on the bubble ring assembly (2). When the film-forming component (52) slides completely over the bubble ring, a closed bubble film is formed inside the bubble ring assembly (2). The liquid guide tube (4) and its absorbent material (43) on the bubble ring play an auxiliary role in liquid supply and film formation during this process.

[0038] Control Logic: The control unit (6) is mounted on the support rod (1) and is connected to the power supply (33) via a power line (62), to the liquid transfer pump (32) via a control line (61), and to the motion motor (53) via a film-forming component (52). The control unit has operation buttons and a built-in programmable controller. The control unit includes the following operating modes: Individual Liquid Supply Mode: Press the individual liquid supply button to start the liquid delivery pump (32), which delivers the bubble solution to the liquid guide tube (4) on the bubble ring and the second liquid guide tube (541) in the automatic coil take-up module (54), ensuring that each absorbent material is fully wetted. Release the button to stop the pump. This mode is used to pre-wet the system after initial assembly or when it has not been used for a long time.

[0039] Single-shot film formation mode: Press the single-shot film formation start button. The control unit (6) first starts the liquid pump (32) for a preset time to keep the absorbent material (43) on the bubble ring (2) and the absorbent material on the film-forming part (52) moist. Then, the motion unit (51) is driven to start from the origin (preferably set at the midpoint of the eleventh guide rail), move along the guide rail for one revolution, return to the origin, and stop. The time for the motion unit to move one revolution can be adjusted according to the viscosity of the bubble solution, preferably 2 seconds. This mode is suitable for single-shot film formation. Continuous film-forming mode: Press the continuous film-forming start button once, and the control unit (6) will automatically cycle through: start the liquid pump (32) to work → drive the moving part (51) to circle once → start the liquid pump (32) to work again → drive the moving part (51) to circle once again... until the user presses the stop button again, and the liquid pump (32) and the moving part (51) stop working. This mode is suitable for players to continuously wave the bubble wand to continuously generate bubbles or to fix the bubble wand in a position with a gentle breeze so that the bubble wand automatically and continuously generates bubbles.

[0040] Alternating forward and reverse rotation mode: The control unit (6) drives the motion part (51) to rotate once in the forward direction and then once in the reverse direction, alternating between the two. In this mode, the film-forming element (52), i.e. the drive wire, will not generate unidirectional torsion accumulation, so the conductive slip ring (55) can be omitted, simplifying the structure.

[0041] Example 2: Wireless drive + scraping film formation + integrated flexible bubble ring like Figure 7 As shown, this embodiment provides an alternative solution that does not require external wires.

[0042] Bubble ring assembly: It adopts an integrated flexible rollable ring, made of elastic memory alloy or high elastic plastic. It can be twisted and folded when stored and automatically pops open to form a ring when used. A liquid guide tube (4) is fixed on the inner side of the ring structure, and the surface of the liquid guide tube is covered with water-absorbing material (43). A guide rail (28) is provided on the outer side of the ring structure, and the moving part (51) moves along the guide rail on the outer side of the ring structure.

[0043] Connection with the support rod: In this embodiment, the connection between the integrated flexible rollable ring and the support rod (1) can adopt the same detachable connection structure as in Embodiment 1 (such as buckle, thread or pin), which will not be described in detail here.

[0044] Movement section: It has a built-in rechargeable battery, motor and wireless control module, with no external wires. When the movement section moves along the ring structure, it is powered by its internal battery.

[0045] Film-forming component: The film-forming component (52) is a flexible absorbent thread, one end of which is fixed to the moving part (51), and the other end is connected to an automatic take-up module (54) (which is fixed to the top of the support rod), used to automatically take up and put down the flexible absorbent thread when the moving part moves. The absorbent thread is soaked in the absorbent material inside the automatic take-up device (miniature coil spring take-up device) to obtain bubble liquid (as the main source), and at the same time slides over the absorbent material on the surface of the liquid guide tube inside the bubble ring, and obtains bubble liquid and evenly coats it by scraping.

[0046] Working process: After the control unit (6) is started, the moving part (51) moves along the outer ring of the ring structure. The flexible absorbent line (52) remains moist during the movement and scrapes against the absorbent material (43) on the surface of the liquid guide tube (4). After one cycle of movement, a closed bubble film is formed. The user can generate bubbles by waving the support rod (1).

[0047] This embodiment does not include a "segmented assembly ring structure", but adopts a flexible and rollable ring structure, which provides another storage method, but still achieves the core function of electric winding film formation.

[0048] Example 3: Inflatable Bubble Ring Component like Figure 8 As shown, this embodiment provides an inflatable bubble ring assembly.

[0049] Bubble ring assembly: Made of flexible, airtight material (such as TPU-coated nylon fabric), with an internal inflation chamber. In use, it is inflated using a manual or electric air pump to form a rigid ring structure; to store, it is deflated and folded. This structure can replace segmented splicing or flexible winding solutions, offering advantages such as light weight and small storage volume.

[0050] Connection with the support rod: In this embodiment, after the inflatable bubble ring assembly is inflated and formed, its connection with the support rod (1) is the same as in the first embodiment. It can adopt a detachable connection structure such as a buckle, thread or pin, which will not be described in detail here.

[0051] Example 4: Detachable and quick-installation structure for liquid guide tube (multiple methods) like Figure 5 As shown, to facilitate the quick installation and removal of the liquid guide tube (4), this embodiment provides a variety of detachable fixing structures. The liquid guide tube (4) is connected to the bubble ring assembly (2) through a detachable fixing structure, which is configured to: fix the liquid guide tube (4) at a predetermined position on the inner side of the bubble ring assembly (2) in the installed state, and allow the liquid guide tube to be separated from the bubble ring assembly in the disassembled state.

[0052] The detachable fixing structure can be a combination of any one or more of the following methods: Method 1 (Magnetic Adsorption): A first magnetic element (41) is arranged along the annular direction on the inner side of the bubble ring assembly (2), and the magnetic poles of the first magnetic element are in the same direction (e.g., both are N poles). The liquid guide tube (4) is preferably flat, and a second magnetic element (42) is arranged along its length on the lower surface of the liquid guide tube, and the magnetic poles of the second magnetic element are opposite to those of the first magnetic element (e.g., both are S poles). When the liquid guide tube approaches the bubble ring assembly, the first magnetic element and the second magnetic element attract each other, automatically adsorbing and fixing the liquid guide tube (4) in a predetermined position. The first magnetic element can be an annular magnetic strip or multiple discretely distributed magnetic blocks embedded in the bubble ring assembly (2); the second magnetic element can be a flexible magnetic strip or a spirally wound magnetic wire embedded in the liquid guide tube. The magnetic elements are preferably neodymium magnets or rubber magnets.

[0053] Method 2 (Hook and Loop): The inner side of the bubble ring assembly is provided with a hook or loop surface along the circumferential direction, and the outer side of the liquid guide tube is provided with a corresponding loop or hook surface, so that it can be detachably fixed by hook and loop fastener.

[0054] Method 3 (slot type): The inner side of the bubble ring assembly is provided with a slot extending in the annular direction, and the liquid guide tube is provided with a locking strip that cooperates with the slot. The liquid guide tube is fixed by sliding the locking strip into the slot.

[0055] Method 4 (Binding type): The bubble ring assembly is provided with multiple binding points, and the liquid guide tube is fixed by elastic straps or ropes.

[0056] Method 5 (Snap-on type): The bubble ring assembly and the liquid guide tube are respectively provided with mating snaps, which are fixed by pressing.

[0057] Those skilled in the art should understand that the above methods are merely illustrative and not exhaustive. Any structure that enables detachable fixing between the liquid guide tube and the bubble ring assembly falls within the scope of protection of this invention. The upper surface of the liquid guide tube (4) has multiple micropores, and the upper surface is covered with absorbent material (43). Both ends are connected to the liquid supply port and the liquid return port of the liquid supply system, respectively. When the liquid guide tube (4) is installed on a flexible, rollable film-forming ring or an inflatable film-forming ring, it will not be excessively stretched and deformed due to folding during storage, and can be fixed on the bubble ring without being removed.

[0058] Example 5: Adaptability to Multiple Sizes The bubble ring component of this invention can be configured with different sizes according to different usage scenarios, all of which can achieve the technical effect of automatic film formation without the need for liquid application. For example, for a child-held version, the bubble ring diameter can be set to 20 cm to 50 cm, which can produce visually significant bubbles and is easy for children to wave; for an adult entertainment version, the diameter can be set to 50 cm to 80 cm, which can produce a larger bubble effect; for a stage performance or a person-looping experience version, the diameter can be set to 80 cm or more, which can allow a small portion of the human body to be encased in the bubbles. Regardless of the size used, the core electric winding film-forming mechanism is the same and falls within the protection scope of this invention.

[0059] Example 6: Storage of Bubble Sticks When storing the bubble rod, if the bubble ring is a multi-segment splicing structure, remove the liquid guide tube (4) installed on the bubble ring assembly (2) and roll it up for storage. Loosen the adjusting bolt, disassemble and fold the bubble ring assembly (2), remove the moving part (51), and let the film forming part (52) be completely put into the automatic winding module (54). Disconnect the connection between the bubble ring assembly (2) and the support rod (1), and then disassemble the support rod (1). Disassemble the bubble rod into small parts and put them into boxes or bags with relatively small length, width and height for easy carrying and transportation. When the bubble ring assembly (2) is a flexible structure, remove the moving part (51) from the bubble ring, disconnect the liquid guide tube (4) on the bubble ring assembly (2) from the liquid supply system (3), roll up and store the flexible bubble ring and the liquid guide tube together, disconnect the flexible bubble ring assembly (2) from the support rod (1), disassemble the support rod (1), disassemble the bubble rod into small parts, and put them into boxes or bags with relatively small length, width and height for easy carrying and transportation; When the bubble ring assembly (2) is an inflatable structure, remove the moving part (51) from the bubble ring, disconnect the connection between the liquid guide tube (4) and the liquid supply system (3) on the bubble ring assembly (2), disconnect the connection between the inflatable bubble ring assembly (2) and the support rod (1), disassemble the support rod (1), vent the bubble ring of the inflatable structure, and then roll up and store the vented bubble ring and the liquid guide tube together. Disassemble the bubble rod into small parts and put them into a box or bag with relatively small length, width and height for easy carrying and transportation.

[0060] This invention discloses a large bubble wand with an electrically driven, wound film-forming mechanism and its film-forming method, which offers significant advantages over existing technologies. Firstly, through a unique film-forming system design, the moving part drives the film-forming component to scrape along a ring structure, efficiently forming a closed bubble film within the large bubble ring. This solves the problem of traditional large bubble tools requiring repeated dipping and failing to automatically form a film. Secondly, the bubble ring assembly can be assembled in various ways, including segmented splicing, flexible winding, and inflation, greatly facilitating carrying, transportation, and storage. Furthermore, wired / wireless dual-mode power supply and multiple control modes (single, continuous, individual liquid supply, alternating forward and reverse rotation) allow the product to adapt to the needs of different users and usage scenarios. The dual liquid supply system design (automatic winding module as the main liquid supply + bubble ring as the auxiliary liquid supply) ensures that the film-forming component remains constantly moist, resulting in a high film-forming success rate. This invention is simple to operate; ordinary users can use it without professional skills, making it highly promising for market application and entertainment value.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
