[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-8The present invention provides a technical solution: a balloon launcher comprising a gun-shaped housing 1 and a blower 11. The housing 1 is formed by joining two parts, left and right. A start button 19 is embedded in the handle portion of the lower portion of the housing 1. An axially retractable launch tube 6 is inserted into the front end of the housing 1. The rear end of the launch tube 6 is provided with a constricted opening where the diameter is reduced. A balloon 21 is inflated within the launch tube 6. A cartridge slot 4 is mounted above the housing 1. The cartridge slot 4 opens from the top and a rotatable cartridge module 5 is mounted therein. The cartridge module 5 comprises a rotating barrel 51. A plurality of axially extending circular holes a are formed along the circumference of the barrel 51. The 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 receive a slender tubular balloon 21. The tail of the core 20 is provided with a resistance head with an enlarged diameter, which is adapted to the magazine 53. The diameter of the circular hole a is larger than the diameter 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 provided with multiple annular flanges in front of the resistance head. The flanges are used to increase the restraint force on the mouth of the balloon 21. The side wall of the core 20 is provided with multiple long air outlet holes to improve the smoothness of the air outlet and facilitate the rapid filling of the balloon. After the balloon 21 is inflated, the mouth of the balloon 21 is expanded and separated from the core 20, and then the balloon is ejected under the reaction of the deflation.

[0022] The front and rear ends of the rotating drum 51 are each provided with an axial tube 54 in the middle. The outer ends of the axial tube 54 are provided with multiple evenly distributed slots 55 along the circumference. The number of slots 55 is equal to that of the magazine 53. Vertical U-shaped slots 8 are provided on both sides of the cartridge slot 4. When installing the cartridge module 5, the axial tube 54 is inserted from top to bottom into the bottom of the U-shaped slot 8. Radially mounted glass ball screws 10 are symmetrically mounted on both sides of the U-shaped slot 8. The steel balls at the front ends of the glass ball screws 10 (when the steel balls are subjected to a pressure greater than a certain value, they elastically retract) engage the slots 55 to position the cartridge module 5 at its rotational angle. Longitudinally retractable positioning blocks 9 are provided on the left and right sides of the U-shaped slot 8. The front ends of the positioning blocks 9 are V-shaped, and the rear ends are spring-loaded. The positioning blocks 9 are used to constrain the axial tube 54 to the bottom of the U-shaped slot 8, preventing the cartridge module 5 from automatically detaching.

[0023] The bottom of the cartridge slot 4 is provided with a horizontally extending circular hole b7. The constriction and the output end of the fan 11 are located at the front and rear ends of the circular hole b7, respectively. The cartridge module 5 rotates in a graduated manner to switch between different magazines 53 and align with the circular hole b7. The fan 11 is installed at the rear end of the inner cavity of the housing 1. The rear end of the housing 1 is provided with a grid-shaped air inlet 2. The output end of the fan 11 is connected to the rear end of the circular hole b7 by an air inlet plug 12. The air inlet plug 12 is a cylindrical structure made of rubber material. The air inlet plug 12 is used to compensate for the docking gap between the port of the fan 11 and the magazine 53 to reduce the leakage of the inflation. The inner cavity of the housing 1 is equipped with a regulated power supply 13 for powering the fan 11. The regulated power supply 13 is externally connected to 220V AC power. The fan 11 is a commercially available product, model CY7020-220V (Chiyang).

[0024] The barrel module 5 is indexed and rotated by a bolt-type drive mechanism, which includes a bolt 3, a push rod 15, and a cylindrical cam 16. The bolt 3 is located on the underside of the launch tube 6 and extends from the housing 1. The push rod 15 is mounted at the rear end of the launch tube 6, and the cylindrical cam 16 is mounted in the housing 1. A pinion 17 is mounted at the rear end of the cylindrical cam 16. A ring gear 52 is provided on the exterior of the rotating drum 51, and the pinion 17 meshes with the ring gear 52. A through-hole is provided at the bottom of the barrel slot 4 at the meshing point. A pin is fixedly mounted at the rear end of the push rod 15, which slides into a curved groove in the cylindrical cam 16. The reciprocating motion of the push rod 15 drives the cylindrical cam 16 to intermittently index and rotate. Each time the push rod 15 is retracted, the cylindrical cam 16 and the pinion 17 rotate a fixed angle. A return spring 14 is provided between the tail end of the launch tube 6 and the cartridge slot 4. The return spring 14 is used to push the launch tube 6 forward and 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 limit position, the fan switch 18 is triggered to turn on. When the push rod 15 moves back to the limit position, the cartridge module 5 rotates one position and a new bullet is loaded.

[0025] Working principle: When in use, the balloons 21 are respectively sleeved on the bullet core 20 one by one, and then loaded into each magazine 53. The loaded cartridge module 5 is card-mounted into the cartridge slot 4. After pressing the start button 19, the pull bolt 3 is pulled backward to make the launch tube 6 move backward synchronously, push the push rod 15 and compress the reset spring 14. The push rod 15 pushes the cylindrical cam 16 to rotate, and the small gear 17 drives the ring gear 52 and the rotating drum 51 to rotate one position, so that the next magazine 53 is aligned with the circular hole b7 (that is, the loaded and ready to be launched state). At the same time, the fan switch 18 is triggered to close, and the fan 11 starts to blow air. The bullet (referring to the balloon 21 and the bullet core 20) is blown forward to the launch tube 6 (the resistance head at the tail of the bullet core 20 cannot pass through the circular hole b7 and still remains at the front end of the magazine 53). The balloon 21 is inflated and lengthened in the launch tube 6. When blown to a certain extent, the mouth of the balloon is separated from the bullet core 20 and deflated and flies out. Then release the bolt 3. Under the thrust of the return spring 14, the launch tube 6 and the push rod 15 move forward and back to their 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 up so that the core 20 without the balloon 21 after launch returns to the magazine 53 under the action of gravity (otherwise the cartridge module 5 cannot be rotated to load a new bullet). Then, the bolt 3 can be pulled back again for the next loading and firing. Therefore, continuous firing can be achieved until all the loaded bullets are used up.

[0026] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
