Description

Technical Field

[0001] This invention relates to the field of children's entertainment toys, and in particular to a blow-driven bubble machine. Background Technology

[0002] Bubble blowing toys are a popular form of entertainment for children. Currently, bubble machines on the market are mainly divided into two categories: manual and electric.

[0003] Traditional manual bubble machines typically include a bubble wand (or bubble ring) soaked in bubble solution. Users need to dip the bubble wand into the solution to create a bubble film, and then blow or wave the wand manually to form bubbles. This method produces only a small number of bubbles at a time, and the bubble solution easily drips, staining hands and clothes, resulting in a poor user experience.

[0004] To address these issues, electric bubble machines have emerged on the market. These products typically have a built-in battery-powered motor that drives fan blades to generate airflow. Simultaneously, a transmission mechanism may drive a scraper or roller to periodically scrape across the bubble-forming opening, achieving automatic blowing and skimming. Users simply trigger a switch to continuously generate large quantities of bubbles. While highly automated, electric bubble machines have new drawbacks: First, relying on battery power leads to battery life issues; once the battery is depleted, the toy becomes unusable, increasing operating costs and environmental burden. Second, the introduction of the motor and transmission structure complicates the product structure, increases cost, size, and weight, reducing portability. Third, electric toys lack the user's direct interaction and primal enjoyment through breathing (blowing), resulting in a more passive experience.

[0005] Therefore, there is a pressing contradiction in the existing technology: how to design a bubble machine that can achieve automated and seamless operation of blowing, liquid supply, and liquid scraping to improve the smoothness and fun of the experience, while also getting rid of dependence on electric motors and batteries, simplifying the structure, reducing costs, and retaining the core fun of user interaction through blowing. Summary of the Invention

[0021] In a further description of the present invention, an arc-shaped baffle is provided on the outer wall of the housing between the scraper and the bubble liquid forming port; the scraper includes a rotating part, a connecting part, and a scraper part connected in sequence; the rotating part is rotatably connected to the housing and connected to the fan blade assembly; the distance between the connecting part and the outer wall of the housing is greater than the height of the arc-shaped baffle protrusion; the scraper part contacts the outer wall of the housing; during the rotation of the scraper, the connecting part avoids the arc-shaped baffle, and the scraper part rotates around the center of the rotating part on the outer periphery of the arc-shaped baffle.

[0022] In a further description of the present invention, two inclined drainage protrusions are provided on the outer wall of the shell between the drainage baffle and the bubble forming port. The two drainage protrusions are respectively used to guide the bubble liquid flowing out of the drain hole to the bubble forming ports on both sides. A gap is reserved between the two drainage protrusions so that the bubble liquid can flow directly down to the bubble forming port in the middle position.

[0023] Further description of the invention: the bubble liquid chamber is formed in the middle of the shell and connected to the top inner wall of the shell; the air inlet is formed at the right end of the shell; the airflow chamber is formed at the left end of the shell; a first air pipe connector is provided on the right side of the airflow chamber; the lower part of the bubble liquid chamber is an airflow channel mounting chamber; a partition is provided on the right side of the airflow chamber; the partition is connected between the inner wall of the shell and the outer wall of the bubble liquid chamber, isolating the air inlet from the airflow channel mounting chamber; a second air pipe connector is installed on the partition; the second air pipe connector communicates with the air inlet; the airflow channel is an air pipe; one end of the air pipe is connected to the first air pipe connector, and the other end is connected to the second air pipe connector.

[0027] As further described in the present invention, the bottom of the housing is provided with a ring-shaped handhold.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. It has created an immersive interactive experience that combines "hand-mouth collaboration," which simplifies operation while retaining the core fun.

[0030] This invention establishes a user-controlled, two-step interactive mode of "hand-press liquid supply and mouth-blowing drive." The user holds the casing with one hand and presses the pump head with the other to supply liquid, while manually blowing air into the nozzle to continuously produce bubbles. It abandons the passive "press-to-play" mode of electric toys, requiring the user to provide all the energy and materials for bubble generation through their own physical actions (pressing and blowing). This moderate level of user involvement simulates the original fun of traditional bubble blowing, while the ingenious mechanical linkage (air-blowing drives the automatic rotation of the scraper) frees the user from the tedious and prone-to-failure repetitive actions of dipping the bubble in liquid and blowing air into it, achieving a perfect balance between fun and ease of play.

[0031] 2. It achieves efficient dual-use of air blowing energy, and the drive structure is simple and reliable.

[0032] The airflow blown by the user is the sole power source for this system. This airflow not only drives the fan blade assembly within the airflow chamber to rotate, transmitting power to the scraper needle to scrape the bubble liquid, but it is also directly used to blow bubbles out from the bubble forming nozzle. This design, with its minimalist purely mechanical structure, achieves dual automatic output of "air supply" and "scraping" triggered by a single input of "blowing," requiring no electricity, exhibiting structural stability, and a low failure rate.

[0033] 3. The gas path and liquid path are physically isolated, ensuring stable system operation and easy maintenance.

[0034] The liquid storage chamber, airflow channel, and drive chamber of this invention are structurally completely isolated. This fundamental design completely eliminates the risk of bubble solution backflow or seepage into the pneumatic system, causing fan blade jamming and gear corrosion, thus ensuring the long-term reliability of the core function powered by air blowing. All functional modules (pump, air circuit, and transmission) are clearly independent, facilitating production assembly and daily cleaning and maintenance.

[0035] 4. The overall structure is compact, with significant cost advantages and no range anxiety.

[0036] By completely eliminating electric components such as batteries, motors, and circuits, and replacing them with an all-mechanical structure, this product has significant advantages in manufacturing cost, weight, and size. Its "energy" comes entirely from the user and is inexhaustible, avoiding the common problems of battery replacement, insufficient battery life, and electronic component aging found in electric toys, making it more environmentally friendly, economical, and durable.

[0037] In summary, this invention successfully combines the interactive fun of traditional bubble blowing with the convenience and efficiency of automated machinery by requiring users to perform coordinated operations of "manual liquid supply" and "mouth blowing." It provides an innovative bubble machine solution that is electricity-free, low-cost, highly reliable, and greatly enhances user engagement and a sense of accomplishment, perfectly addressing the technical contradictions raised in the background section.

[0043] The present invention will be further described below with reference to the accompanying drawings:

[0044] like Figure 1-5 As shown, a blow-driven bubble machine includes:

[0045] The shell 1 has a bubble liquid chamber 11 and an airflow chamber 12 formed inside it;

[0046] A liquid inlet 2 is formed on the bubble liquid chamber 11 and is used to inject bubble liquid.

[0047] The press pump 3 is installed in the bubble liquid chamber 11, and its press head 31 extends from the top of the bubble liquid chamber 11 to pump out the bubble liquid in the bubble liquid chamber 11.

[0048] The bubble liquid channel 4 is used to guide the bubble liquid pumped out by the press pump 3 to a predetermined area on the outer wall of the housing 1;

[0049] An air inlet 13 is formed on the housing 1 for the user to blow in gas;

[0050] An airflow channel 5 is disposed inside the housing 1, with one end connected to the air blowing port 13 and the other end connected to the airflow chamber 12;

[0051] The fan blade assembly 6 is rotatably disposed within the airflow chamber 12, and the airflow guided by the airflow channel 5 can impact and drive the fan blade assembly 6 to rotate.

[0052] A bubble forming port 14 is formed on the shell 1 and communicates with the airflow chamber 12, so that the airflow flowing through the airflow chamber 12 can be blown out from here;

[0053] The scraper 7 is rotatably connected to the housing 1 and to the power output end of the fan blade assembly 6. Its movement trajectory passes through the bubble forming opening 14 and is used to scrape off the bubble liquid accumulated at the bubble forming opening 14.

[0054] The bubble liquid flowing out from the bubble liquid channel 4 can flow along the outer wall of the shell 1 to the bubble forming port 14, where it meets the airflow blown out from the bubble forming port 14 to form bubbles.

[0055] In use, a certain amount of bubble solution is injected into the bubble solution chamber 11 through the supply port 2. Then, the user holds the housing 1 with one hand and presses the press head 31 of the press pump 3 with the other hand. After pressing the press head 31, the press pump 3 draws bubble solution from the bubble solution chamber 11 and supplies it to the outer wall of the housing 1 through the bubble solution channel 4. The solution flows along the outer wall to the bubble forming port 14. At the same time, air is blown into the air blowing port 13. The blown air is supplied to the air flow chamber 12 through the air flow channel 5. This air flow impacts and drives the fan blade assembly 6 to rotate, which in turn drives the scraper needle 7 to rotate. As the airflow is generated, it blows out from the bubble forming port 14. The blown air and the bubble liquid in the bubble forming port 14 converge to form bubbles. During the rotation of the scraper needle 7, the bubble liquid accumulated at the bubble forming port 14 is scraped off, so that bubbles can be continuously formed. By requiring users to perform the coordinated operation of "hand-pressing liquid supply" and "mouth blowing drive", the interactive fun of traditional bubble blowing is successfully combined with the convenience and efficiency of automated machinery. It provides an innovative bubble machine solution that requires no electricity, is low-cost, highly reliable, and can greatly stimulate users' sense of participation and accomplishment.

[0056] A pipe through-hole 111 is provided on one side of the upper part of the bubble liquid chamber 11; the bubble liquid channel 4 includes a supply pipe 41, a supply pipe connector fixing seat 42, and a drainage baffle 43; the supply pipe connector fixing seat 42 is fixed to the inner wall of the housing 1 and forms a liquid passage chamber 401 between the supply pipe and the inner wall of the housing 1; a supply pipe connector 421 is provided on one side of the supply pipe connector fixing seat 42; one end of the supply pipe 41 is connected to the outlet of the press pump 3, the middle part extends out of the bubble liquid chamber 11 from the pipe through-hole 111, and the other end is connected to the supply pipe connector 421; a drain hole communicating with the liquid passage chamber 401 is formed on the housing 1. 15; The flow-guiding baffle 43 is fixed to the outer wall of the housing 1 and located outside the drain hole 15, guiding the bubble liquid flowing out of the drain hole 15 downwards. The inlet of the press pump 3 is also connected to the bottom of the bubble liquid chamber 11 through a pipe for extracting bubble liquid. After the press pump 3 extracts bubble liquid from the bubble liquid chamber 11, it is discharged through the supply pipe 41 to the liquid chamber 401, and then flows out from the drain hole 15 to the outer wall of the housing 1. When the bubble liquid flows out, the guide baffle plays a blocking and guiding function to prevent the bubble liquid from spraying out. It flows downwards along the flow-guiding baffle 43, allowing the bubble liquid to flow to the position of the bubble forming port 14.

[0057] In this design, three bubble forming ports 14 are provided and are evenly distributed in a circular pattern on the upper part of the scraper 7; the bubble forming ports 14 are located at the lower part of the flow guide baffle 43, and bubbles can be blown out from the three bubble forming ports 14 at the same time, thereby increasing the amount of bubble forming.

[0058] An arc-shaped baffle 16 is provided on the outer wall of the housing 1 between the scraper 7 and the bubble liquid forming opening; the scraper 7 includes a rotating part 71, a connecting part 72, and a scraper part 73 connected in sequence; the rotating part 71 is rotatably connected to the housing 1 and connected to the fan blade assembly 6; the distance between the connecting part 72 and the outer wall of the housing 1 is greater than the height of the arc-shaped baffle 16; the scraper part 73 contacts the outer wall of the housing 1; during the rotation of the scraper 7, the connecting part 72 avoids the arc-shaped baffle 16, and the... The scraper needle 73 rotates around the center of the rotating part 71 on the outer periphery of the arc-shaped baffle 16. The arc-shaped baffle 16 is designed to prevent the downward-flowing bubble liquid from flowing onto the rotating part 71 of the scraper needle 7, thus providing a protective effect. The rotating part 71 of the scraper needle 7 is connected to the scraper needle 73 through the connecting part 72. When the connecting part 72 rotates, it can avoid the arc-shaped baffle 16, allowing the scraper needle 7 to rotate continuously and smoothly. The scraper needle 73 cleans all the bubble forming openings 14 once every time it rotates, and it can continue to rotate and clean during the operation.

[0059] On the outer wall of the housing 1, two inclined drainage protrusions 17 are provided between the drainage baffle 43 and the bubble forming port 14. The two drainage protrusions 17 are used to guide the bubble liquid flowing out of the drain hole 15 to the bubble forming ports 14 on both sides. A gap is reserved between the two drainage protrusions 17 so that the bubble liquid can flow directly down to the middle bubble forming port 14. The bubble liquid flowing down from the drainage baffle 43 is further guided by the two drainage protrusions 17 to the three bubble forming ports 14, so that each bubble forming port 14 is continuously replenished with bubble liquid to form bubbles.

[0060] The bubble liquid chamber 11 is formed in the middle of the shell 1 and connected to the top inner wall of the shell 1; the air inlet 13 is formed at the right end of the shell 1; the airflow chamber 12 is formed at the left end of the shell 1; a first air pipe connector 121 is provided on the right side of the airflow chamber 12; the lower part of the bubble liquid chamber 11 is an airflow channel installation chamber; a partition 18 is provided on the right side of the airflow chamber 12; the partition 18 is connected between the inner wall of the shell 1 and the outer wall of the bubble liquid chamber 11, and the air inlet 13... The partition 18 is isolated from the airflow channel installation chamber; a second air pipe connector 181 is installed on the partition 18; the second air pipe connector 181 is connected to the air blowing port 13; the airflow channel 5 is an air pipe; one end of the air pipe is connected to the first air pipe connector 121, and the other end is connected to the second air pipe connector 181. The user blows gas into the air blowing port 13, and the airflow enters from the position of the second air pipe connector 181, is discharged to the first air pipe connector 121 through the air pipe, and is discharged into the airflow chamber 12 from the first air pipe connector 121.

[0061] The first air pipe connector 121 has two adjacent exhaust ports formed on it. The two exhaust ports act on the fan blade assembly 6, which is beneficial to the rotation of the fan blade assembly 6.

[0062] The fan blade assembly 6 includes a fan blade 61, a first mounting shaft 62, a drive gear 63, a double transmission gear 64, a second mounting shaft 65, and a driven gear 66. The fan blade 61 is rotatably connected to the airflow chamber 12 via the first mounting shaft 62. The drive gear 63 is fixed to one side of the fan blade 61. The transmission gear is fixedly connected to the scraper needle 7. The double transmission gear 64 is rotatably connected to the airflow chamber 12 via the second mounting shaft 65 and meshes with the drive gear 63 and the driven gear 66 respectively. The airflow supplied to the airflow chamber 12 through the airflow channel 5 impacts the fan blade 61 of the fan blade assembly 6, thereby driving the fan blade 61 to rotate. The fan blade 61 transmits power to the scraper needle 7 through the meshing of the drive gear 63, the double transmission gear 64, and the drive gear 63, controlling the rotation of the scraper needle 7. The gas in the airflow chamber 12 is discharged from the bubble forming port 14 and merges with the bubble liquid at the location of the bubble forming port 14 to form bubbles.

[0063] Two support plates 112 are installed in the middle of the bubble liquid chamber 11, arranged on the left and right. The support plates 112 are provided with slots 1121. The main body of the press pump 3 is installed on the slots 1121 of the two support plates 112, and the press head 31 of the press pump 3 extends from the top of the housing 1. A plug 21 is installed on the liquid supply port 2. A pull ring 211 is installed on one side of the plug 21. It also includes a liquid supply funnel 8. After removing the plug 21, the liquid supply funnel 8 is used to connect to the liquid supply port 2 for supplying bubble liquid. This installation method is stable, and the press head 31 of the press pump 3 can be pressed directly from above by the operator, which is convenient to operate. When bubble liquid needs to be replenished, the pull ring 211 is pulled to pull out the plug 21 and insert it into the liquid supply funnel 8. The bubble liquid can then be poured into the liquid supply funnel 8 and supplied into the bubble liquid chamber 11. After injecting the bubble liquid, the liquid supply funnel 8 is removed and the plug 21 is reinstalled.

[0064] The bottom of the housing 1 is provided with a ring-shaped handhold 19 for easy manual handling.

[0065] The above description is not intended to limit the scope of the present invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the present invention.
