Description

The present invention relates to the technical field of toy guns, and particularly to a toy gun whose light source beam can be adjusted.

Toy guns are very popular among children and young people and are commonly used for games and sporting activities, such as hunting games, fighting or war games. Toy guns are generally designed to resemble real guns, and are also equipped with light and sound effects to create a sense of realism and attract players.

However, conventional toy guns are rarely used in the dark because in the dark, players cannot see the effect of the bullets being shot from the toy gun, which further reduces the excitement and fun felt by players when using the toy gun in the dark. In recent years, some improvements have been made to toy guns, adding a luminous bullet function, which allows players to play shooting games in the dark. The luminous bullets of these toy guns are generally coated with fluorescent or phosphorescent pigments, and in order to achieve the desired luminous effect, the bullets need to be exposed to a light source before being shot from the toy gun. One of the disadvantages of conventional luminous bullets is that the bullets need to be exposed to a light source to make them glow before starting the game. As a result, it brings inconvenience to players and makes it difficult to start the game immediately because the preparation time for exposing the bullets to the light source is longer. Also, if the bullets are unevenly exposed to the light source or the time of exposure to the light source is insufficient, the desired luminous effect cannot be provided after the bullets are shot from the toy gun, which further reduces the overall excitement of the game.

Currently, a toy gun has been disclosed that can produce the visual effect of luminous soft bullets similar to space weapons without exposing the soft bullets to a light source beforehand, thus reducing game preparation time, while this toy gun The spot size of the light source beam cannot be adjusted, which reduces the fun of toy guns.
