Projection device

A projection device, comprising:

• first light sources configured to generate projection light;
• an interference disk arranged on light paths of the first light sources;
• a condensing lampshade arranged on the light paths of the first light sources and behind the interference disk;
• and
• a driving device configured to drive the condensing lampshade to rotate;
• wherein the projection light generated by the first light sources generates an interference effect after passing through the interference disk;
• the projection light generated by the first light sources sequentially passes through the interference disk and the condensing lampshade to emit;
• when the driving device drives the condensing lampshade to rotate, the projection light emitted after sequentially passing through the interference disk and the condensing lampshade projects an effect of clouds moving;
• wherein the projection device further comprises a housing and a mounting bracket;
• the housing defines a lampshade hole;
• the mounting bracket is arranged in the housing and is arranged at a position corresponding to a position of the lampshade hole;
• the condensing lampshade is mounted in the lampshade hole;
• wherein side walls of the mounting bracket are enclosed to form a light channel;
• the first light sources are mounted on a light board, both of the light board and the interference disk are mounted on the mounting bracket;
• the light board and the interference disk are separately arranged on two ends of the light channel;
• the interference disk is arranged on one end of the light channel close to the condensing lampshade.

• wherein the driving device comprises a motor and a gear directly or indirectly driven by the motor;
• the condensing lampshade comprises a tooth portion;
• the tooth portion comprises meshing teeth engaged with the gear;
• when the motor drives the gear to rotate, the gear drives the condensing lampshade to rotate through the tooth portion;
• wherein the projection device further comprises a housing and a mounting bracket;
• the housing defines a lampshade hole;
• the mounting bracket is arranged in the housing and is arranged at a position corresponding to a position of the lampshade hole;
• the condensing lampshade is mounted in the lampshade hole;
• and
• wherein the motor is mounted on the mounting bracket;
• the gear is mounted on an output shaft of the motor;
• a through hole is formed on the mounting bracket;
• the gear passes through the through hole and is drivably connected with the tooth portion.
