Abstract
A miniature pump includes an upper shell, an air bag and a lower shell. The air bag is formed on the upper shell. The lower shell is connected to the upper shell in an air-tight manner. The air bag is compressible to pump air from it and expansible to suck air into it. The lower shell includes two grids for reinforcement so that the lower shell is not deformed when the air bag is compressed on the lower shell.
