WIND-DRIVEN BUBBLE GENERATING DEVICE AND APPLICATION THEREOF

Description

TECHNICAL FIELD

The present disclosure relates to the field of bubble generating devices, and in particular to a wind-driven bubble generating device and an application thereof.

BACKGROUND

As an entertainment and decoration equipment, bubble generating devices are commonly found in playgrounds, celebrations and home environments. The basic principle is to make the bubble liquid form a liquid film through a certain power source, and use airflow to separate the liquid film into bubbles. Most traditional bubble machines are electric, relying on motors to drive fans or pumps to generate airflow and transport bubble liquid. Although such devices are popular, the inherent defects thereof limit the scope of application: the devices rely on batteries or external power supplies, which not only increases the cost of use (frequent battery replacement or charging), but also severely restricts the usage scenarios thereof, making the devices unable to work stably for a long time in outdoor environments or large inflatable entertainment facilities lacking power.

With the vigorous development of the outdoor entertainment industry, especially inflatable amusement facilities (such as bouncy castles), the market demand for automated bubble devices that do not require electricity and can utilize the natural wind power of the environment has become increasingly prominent. At present, there have been some bubble devices that try to utilize wind power. However, these related arts are generally simple in structure and single in function. Most of these related arts lack effective regulating mechanism, the air inlets thereof are fixed in size, and it is impossible to adjust the air intake adaptively according to the strength of the external wind. This causes the device to fail to start and work effectively under light wind conditions, while under strong wind conditions, the bubble liquid can be rapidly exhausted due to excessive air influx, serious waste, and even the equipment can be damaged due to excessive internal mechanism rotation speed. In addition, the existing wind-powered bubble devices mostly adopt integrated or non-detachable closed structures, which makes it extremely difficult for users to clean, maintain or replace key components (such as bubble rings stained with bubble liquid), and the hygienic conditions and product service life are affected. At the same time, the mounting methods of existing wind-powered bubble devices are often quite limited, typically allowing only for horizontal placement, and it is difficult to securely fix or integrate onto the vertical walls of inflatable castles, tents, or other non-flat fabric surfaces, greatly limiting the application potential of the existing wind-driven bubble devices.

Therefore, the wind-driven bubble device in the related art has problems including non-adjustable, difficult maintenance, single mounting mode, and poor environmental adaptability. There is an urgent need for an innovative solution in the field to provide a bubble generating device driven purely by wind power, featuring linearly adjustable air intake volume, easy disassembly and cleaning, and flexible mounting on various carriers, thereby meeting broader market application demands.

An objective of the present disclosure is to provide a wind-driven bubble generating device, a core design concept is to completely utilize environmental wind or airflow generated by inflatable equipment as a power source, realize automatic production of bubbles through a set of exquisite mechanical structures, and simultaneously endow the device with excellent adjustability, maintainability and mounting flexibility.

To make the above objectives, features and advantages of the present disclosure more obvious and understandable, the present disclosure is further explained in detail in combination with the accompanying drawings and specific embodiments.

Example 1

Referring to FIGS. 1-5, the bubble generating device mainly includes a base body 1, a functional movement, a regulating mechanism, and a bubble generating ring 2.

The base main body 1 constitutes a basic frame and shell of the device, which is usually molded by injection molding process and has good structural strength and weather resistance. A liquid inlet interface 3 is disposed in a center of a bottom of the base body 1, which is used to connect to an external bubble liquid container through a length of hose (such as a silicone tube). To ensure reliable connection and prevent leakage, the liquid inlet interface 3 is usually arranged with a fixing clamp or a compression member as a fixing member, and a sealing ring is arranged at a butt joint with a bottom of the functional movement to form a leakage-proof sealing structure together. An interior of the base body 1 forms a cavity for accommodating and protecting the core functional movement. A plurality of first air inlets 4 are uniformly disposed on a lower side wall of the base body 1 in a circumferential direction, and these air inlets are main channels for external airflow to enter an interior of the device.

As a core component of the whole device, the functional movement is designed as a modular unit that can be disassembled as a whole, which greatly facilitates cleaning, maintenance and component replacement. The movement is detachably mounted in the cavity of the base body 1 by a fixing cover 7. One of the core components of the functional movement is a cup-shaped air regulating member 8. The cup-shaped air regulating member 8 is rotatably supported in the base body 1 by means of a bearing or a sleeve structure. A plurality of second air inlets 11 are disposed on a side wall of the cup-shaped air regulating member 8 in a circumferential direction, and positions of these air inlets initially correspond to the first air inlets 4 on the base body 1. The unique feature of the cup-shaped air regulating member 8 is that an outer edge thereof is arranged with a section of arc-shaped driven teeth 15.

The regulating mechanism is a key for a user to interact with the device and realize the function control. The regulating mechanism mainly includes a knob 12 which is directly operable by the user. The knob 12 is rotatably mounted on a side portion of a second mounting edge 6 of the base body 1 by means of a rotating shaft 13. A bottom of an inner side of the knob 12 is arranged with an annular driving teeth 14. When the user rotates the knob 12, the driving teeth 14 are engaged with the driven teeth 15 at an edge of the cup-shaped air regulating member 8 to form a gear transmission mechanism, thereby accurately converting rotary movement of the knob 12 into rotation of the cup-shaped air regulating member 8. By rotating the cup-shaped air regulating member 8, overlapping areas between the second air inlets 11 on the side wall thereof and the first air inlets 4 on the base body 1 can be changed. This design realizes the linear stepless adjustment of the air inlets: the larger the overlapping area, the larger the air inlet volume; otherwise, the smaller it is. This enables the user to finely control the airflow rate entering the device according to the strength of the external wind, thereby ensuring the start-up in gentle breeze, avoiding waste and overload in strong wind, and achieving precise control of the bubble output volume and the rotational speed of the bubble generating ring 2. A side wall of the knob 12 is usually arranged with anti-slip patterns, and a top of the knob 12 can also be arranged with an indicating arrow to improve the intuition of operation.

A set of pneumatic assembly is arranged above the cup-shaped air regulating member 8. The assembly mainly includes a fan blade 10 included by a plurality of blades. The fan blade 10 is rotatably mounted in a fixing ring 16 by a central axis, and the fixing ring 16 is fixed above the fixing cover 7. When the airflow enters the interior of the device from regulated air inlets, the airflow impacts the blades of the fan blade 10, thereby driving the fan blade 10 to rotate. The bubble generating ring 2 is mounted directly or indirectly above the fan blade 10 and rotates synchronously therewith.

A liquid path system is responsible for delivering bubble liquid from a container to the bubble generating ring 2. In a preferred example of the present disclosure, a peristaltic pump 9 indirectly driven by wind power without electricity is adopted. The peristaltic pump 9 is usually located below the cup-shaped air regulating member 8, and power input of the peristaltic pump 9 is associated with the rotation of the fan blade 10 or the cup-shaped air regulating member 8. A roller of the peristaltic pump 9 squeezes a section of silicone hose, one end of the silicone hose is connected to the liquid inlet interface 3 at the bottom, and the other end of the silicone hose pumps the bubble liquid to a liquid outlet point located at a top of a rotating shaft or directly to the bubble generating ring 2. Wind power is simultaneously used to drive the bubble generating ring 2 and the peristaltic pump 9, ensuring that the supply of the bubble liquid is synchronized with the formation of the bubble film.

The bubble generating ring 2 rotates at a high speed with the fan blade 10, and an annular structure of the bubble generating ring 2 dips and forms a uniform liquid film when the bubble generating ring 2 passes over stored bubble liquid. At this time, airflow entering from the bottom and flowing through the interior of the device is blown just upward towards the rotating bubble generating ring 2, blowing the liquid film away from the ring body, thereby forming countless uniform size bubbles, which are sprayed out from an opening at the top of the device and dispersed by the wind.

The top design of the base body 1 is crucial for mounting adaptability. A top edge of the base body 1 is arranged with a ring of first mounting edge 5. A second mounting edge 6 is detachably sealed and fixed to the first mounting edge 5 through means including buckle, screw or rotary snap-fit. An important function of this openable sealing structure is to allow the whole bubble generating device to be clamped and fixed like a “button” to the fabric wall of inflatable objects including an inflatable castle, an inflatable tent, or the like. The continuous airflow generated by the blower of the inflatable object just provides a steady and powerful wind source for the device. A bottom of the fixing cover 7 is arranged with buckles 17, and a surface of the second mounting edge 6 is disposed with corresponding clamping grooves 18. When mounting the movement, the fixing cover 7 only needs to be pressed, aligned and rotated for a certain angle, the buckles 17 can be locked with the clamping grooves 18, and the functional movement can be reliably fixed inside the device; and when the fixing cover 7 is rotated reversely, the whole movement can be unlocked and taken out, which is very convenient for cleaning and maintenance.

In practical applications, the device of the present disclosure exhibits extremely high flexibility. In addition to utilizing the blast airflow of the inflatable castle itself, the device can also work when there is natural wind outdoors. There are various ways to mount the device: in addition to the above-mentioned way of clamping on inflatable objects, additional mounting holes can be designed on the base body 1 for matching with Velcro, cable ties, ropes or screws to fix the device on railings, tree trunks, tent poles and other objects. Or, quick-release structures including Velcro and buckles can be adapted at the bottom of the base to meet the needs of more varied scenes.

All in all, in the present disclosure, wind energy is skillfully converted into mechanical energy generated by driving bubbles through pure mechanical structure, and the working state is accurately controlled through linear adjustment mechanism. The maintenance problem is solved through modular design, and the application boundary is broadened through various mounting methods, becoming a truly efficient, convenient, reliable and widely applicable wind-driven bubble solution.
