Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a balloon launcher. Background Technology

[0002] Balloons typically consist of a sphere and an inflation valve, with a rubber ring at the inflation valve. One way to play with a balloon is to inflate it, pinch the inflation valve, and then release it with the valve pointing downwards; the balloon will then fly out freely due to the reaction force (launch). A search revealed a Chinese utility model patent (CN214105813U) that discloses a balloon launcher. This toy can fix and release a balloon, including a vertical tube. The tube is a cylindrical shape with openings at both ends. The lower end has a first plug, the lower end of which protrudes from the tube and has a first annular protrusion on its side. The center of the first plug has a first through hole with a one-way valve. The upper end of the tube has a fixing structure that works with the balloon. Its structure is simple, portable, and enables balloon inflation and launch. However, the launcher can only launch one balloon at a time, and it requires manual inflation, limiting its experiential and fun aspects as a toy. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-8This utility model provides a technical solution: a balloon launcher, including a gun-shaped shell 1 and a blower 11. The shell 1 is composed of two parts joined together. A start button 19 is embedded in the handle at the bottom of the shell 1. An axially retractable launch tube 6 is inserted into the front end of the shell 1. The tail end of the launch tube 6 has a constricted end with a smaller diameter. The balloon 21 is inflated inside the launch tube 6. A cartridge slot 4 is installed on the top of the shell 1. A rotatable cartridge module 5 is inserted into the cartridge slot 4 through an opening on the top side. The cartridge module 5 includes a rotating cylinder 51. The edge of the rotating cylinder 51 has multiple axially penetrating circular holes a along the circumference. The circular holes a are evenly distributed along the circumference to form a cartridge chamber 53. A tubular cartridge core 20 is inserted into the cartridge chamber 53. The cartridge core 20 is used to fit the slender tubular balloon 21. The tail of the core 20 is equipped with a stop with an increased diameter, which is adapted to the cartridge 53. The diameter of the circular hole a is larger than that of the circular hole b7 (so that the tail of the core 20 cannot slide out of the circular hole b7). The core 20 is equipped with multiple annular flanges in front of the stop, which are used to increase the restraint on the mouth of the balloon 21. The side wall of the core 20 is equipped with multiple elongated air outlets to improve the smoothness of air release and facilitate the rapid filling of the balloon. After the balloon 21 is inflated, the mouth of the balloon 21 is stretched and detached from the core 20. Then the balloon is ejected under the reaction force of deflating.

[0022] Both ends of the rotating drum 51 have a central tube 54 at the middle. Multiple evenly distributed slots 55 are provided along the circumference of the outer end of the central tube 54. The number of slots 55 is equal to the number of magazines 53. Vertical U-shaped grooves 8 are provided on both sides of the magazine groove 4. When installing the magazine module 5, the central tube 54 is inserted from top to bottom into the bottom of the U-shaped groove 8. Radial ball screws 10 are symmetrically installed on both sides of the U-shaped groove 8. The steel ball at the front end of the ball screw 10 (which elastically retracts when subjected to a compressive force greater than a certain value) engages with the slot 55 to position the rotation angle of the magazine module 5. Longitudinal telescopic positioning blocks 9 are provided on the left and right sides of the U-shaped groove 8. The front end of the positioning block 9 is V-shaped, and the tail end is pushed by a spring. The positioning blocks 9 are used to constrain the central tube 54 to the bottom of the U-shaped groove 8, preventing the magazine module 5 from automatically detaching.

[0023] The bottom of the cartridge slot 4 has a horizontally penetrating circular hole b7. The constricted end and the output end of the blower 11 are located at the front and rear ends of the circular hole b7, respectively. The cartridge module 5 rotates in increments to switch between different cartridge chambers 53 aligned with the circular hole b7. The blower 11 is installed at the rear of the inner cavity of the housing 1. The rear of the housing 1 has a mesh-like air inlet 2. The output end of the blower 11 is connected to the rear end of the circular hole b7 through an air inlet plug 12. The air inlet plug 12 is a cylindrical structure made of rubber. The air inlet plug 12 is used to compensate for the mating gap between the blower 11 port and the cartridge chamber 53, reducing air leakage during inflation. The inner cavity of the housing 1 is equipped with a regulated power supply 13 for powering the blower 11. The regulated power supply 13 is connected to a 220V AC mains power supply. The blower 11 is a commercially available product, model CY7020-220V (Chiyang).

[0024] The cartridge module 5 is driven by a bolt-type drive mechanism for indexing. The bolt-type drive mechanism includes a bolt 3, a push rod 15, and a cylindrical cam 16. The bolt 3 is located on the lower side of the firing tube 6 and extends from the housing 1. The push rod 15 is installed at the tail end of the firing tube 6. The cylindrical cam 16 is installed in the housing 1, and a pinion 17 is provided at the rear end of the cylindrical cam 16. A gear ring 52 is provided on the outside of the rotating cylinder 51. The pinion 17 meshes with the gear ring 52. A through hole is provided at the bottom of the cartridge slot 4 at the meshing part. A pin is fixedly installed at the tail end of the push rod 15. The pin is slidably connected to the curved groove on the cylindrical cam 16. The reciprocating motion of the push rod 15 drives the cylindrical cam 16 to intermittently index. Each time the push rod 15 is pulled back, the cylindrical cam 16 and the pinion 17 rotate at a fixed angle. A reset spring 14 is provided between the tail end of the launch tube 6 and the cartridge slot 4. The reset spring 14 is used to push the launch tube 6 forward to reset after the pull bolt 3 is pulled back. A fan switch 18 is installed in the housing 1. When the push rod 15 moves back to the extreme position, it triggers the fan switch 18 to turn on. When the push rod 15 moves back to the extreme position, the cartridge module 5 rotates one position and loads a new cartridge.

[0025] Working principle: In use, balloons 21 are fitted one by one onto the core 20, and then the ammunition is loaded into each magazine 53. The loaded magazine module 5 is inserted into the magazine slot 4. After pressing the start button 19, the pull bolt 3 is pulled back, which causes the launch tube 6 to move backward synchronously, pushing the push rod 15 and compressing the return spring 14. The push rod 15 pushes the cylindrical cam 16 to rotate, and the pinion 17 drives the gear ring 52 and the rotating cylinder 51 to rotate one position, so that the next magazine 53 is aligned with the round hole b7 (i.e., loaded and ready to fire). At the same time, the blower switch 18 is triggered to close, and the blower 11 runs and blows air. The ammunition (referring to balloons 21 and core 20) is blown forward to the launch tube 6 (the head at the tail of the core 20 cannot pass through the round hole b7 and remains at the front end of the magazine 53). The balloon 21 is inflated and lengthened in the launch tube 6. When it is blown to a certain extent, the mouth of the balloon separates from the core 20 and deflates and flies out. Then, the bolt 3 is released, and under the pushing force of the return spring 14, the launch tube 6 and the push rod 15 move forward back to their original positions. Since the end of the push rod 15 is disengaged from the fan switch 18, the fan 11 stops working. Then, the launcher is tilted upward, so that the projectile core 20 without the balloon 21 after launch returns to the magazine 53 under the action of gravity (otherwise the magazine module 5 cannot be rotated to load a new round). Then, the bolt 3 can be pulled back again to load and fire the next round. Therefore, continuous firing can be achieved until all the loaded rounds are fired.
