Inflation bulb

Abstract

An inflation bulb has a body and two gas nozzles. The body has a bulb chamber, an outlet chamber, and two ventilating ducts. The two ventilating ducts are located between the bulb chamber and the outlet chamber, separated from each other, and individually communicating with the bulb chamber and the outlet chamber. The two gas nozzles are respectively disposed in the two ventilating ducts. Each gas nozzles includes two slices overlapping with each other and selectively separated from each other to form an air passage communicating with the bulb chamber and the outlet chamber. Each valve slice has a first end being triangular and extending into the bulb chamber. The inflation bulb is suitable to be disposed in a wearable device to inflate an inflatable object placed inside the wearable device while the wearable device is worn by a user.

What is claimed is: 
     
         1 . An inflation bulb comprising:
 a body having
 an upper membrane; 
 a lower membrane connected to the upper membrane; 
 a bulb chamber formed between the upper membrane and the lower membrane; 
 an outlet chamber formed between the upper membrane and the lower membrane and spaced apart from the bulb chamber; and 
 two ventilating ducts located between the bulb chamber and the outlet chamber, arranged side by side, separated from each other, and individually communicating with the bulb chamber and the outlet chamber; 
   two gas nozzles respectively disposed in the two ventilating ducts between the bulb chamber and the outlet chamber, each gas nozzle including
 two valve slices aligned with and overlapping with each other, selectively separated from each other to form an air passage between the two valve slices and communicating with the bulb chamber and the outlet chamber, each valve slice having a first end being triangular and extending into the bulb chamber; and 
   a deflation valve connected to the body and selectively communicating with the outlet chamber.   
     
     
         2 . The inflation bulb as claimed in  claim 1 , wherein each valve slice of each gas nozzle has a second end being rectangular and extending into the outlet chamber. 
     
     
         3 . The inflation bulb as claimed in  claim 2 , wherein the two ventilating ducts are separated by a separating wall. 
     
     
         4 . The inflation bulb as claimed in  claim 3 , wherein the inflation bulb comprises an intake valve securely mounted to a bottom of the lower membrane and selectively communicating with the bulb chamber. 
     
     
         5 . The inflation bulb as claimed in  claim 4 , wherein the intake valve has multiple protrusions spaced from each other, located outside of the body, and facing away from the lower membrane. 
     
     
         6 . The inflation bulb as claimed in  claim 5 , wherein the body has a vent communicating with the outlet chamber and located at an end of the body opposite to the bulb chamber.
