Bubble machine

Abstract

The present invention provides a bubble machine, which comprises, a film forming nozzle, a fan and a liquid storage, chamber. The fan is used to make airstream flow to the film forming nozzle. The bubble machine further comprises a film coating body, a rotation driving device and a bubble liquid flow path, the bubble liquid in the liquid storage chamber is capable of flowing to the film forming nozzle through the bubble liquid flow path, the film coating body is driven to rotate by the rotation driving device, and the axis of rotation of the film coating body is located on one side of the film forming nozzle and the film coating body is attached to the surface of the film forming nozzle. The film coating body causes the bubble to form a film on the film forming nozzle during rotation.

What is claimed is: 
     
         1 . A bubble machine, comprising a film forming nozzle, a fan and a liquid storage chamber, wherein the fan is used to make airstream flow to the film forming nozzle, wherein the bubble machine further comprises a film coating body, a rotation driving device and a bubble liquid flow path, the bubble liquid in the liquid storage chamber is capable of flowing to the film forming nozzle through the bubble liquid flow path, the film coating body is driven to rotate by the rotation driving device, and the axis of rotation of the film coating, body is located on one side of the film forming nozzle and the film coating body is attached to the surface of the film forming nozzle, and the film coating body causes the bubble to form a film on the film forming nozzle during rotation. 
     
     
         2 . The bubble machine according to  claim 1 , further comprising a smoke generator, and the airstream generated by the fan makes the smoke generated by the smoke generator flow to the windward side. 
     
     
         3 . The bubble machine according to  claim 2 , wherein a smoke storage tank for storing the smoke generated by the smoke generator is further installed on the air flow path. 
     
     
         4 . The bubble machine according, to  claim 1 , wherein the film coating body is affixed to the leeward side of the film forming nozzle. 
     
     
         5 . The bubble machine according to  claim 1 , wherein the bubble liquid flow path comprises a liquid flow tube, the liquid flow tube is provided between the first gear and the second gear that mesh with each other, the rotation direction of the first gear is fixed, and the first gear and the second gear squeeze the liquid flow tube to suck the bubble in the liquid storage chamber to the film forming nozzle. 
     
     
         6 . The bubble machine according to  claim 5 , wherein the first gear is in transmission connection with the rotation driving device, a third gear is provided on the axis of rotation connected to the film coating body, and the first gear is also meshed with the third gear. 
     
     
         7 . The bubble machine according to  claim 1 , wherein the bubble liquid in the liquid storage chamber is pumped to the film forming nozzle by a power pump. 
     
     
         8 . The bubble machine according to  claim 1 , wherein the bubble liquid in the liquid storage chamber flows to the film forming nozzle by gravity. 
     
     
         9 . The bubble machine according to  claim 1 , wherein a liquid collecting tank is provided below the film coating body and as the film coating body rotates, the end of the film coating body is capable of running into the liquid collecting tank.
