Abstract

An inflating device has a housing, a first air pump, and a first control device. The first control device has a casing, a thin film, a pushing member, a lever, a pressing member, a rotating knob, and a micro switch. The thin film is mounted in an inner space of the casing to divide the inner space into a first chamber and a second chamber. The pushing member has a bottom end abutting against the thin film. The lever is mounted pivotally in the housing and has a first end abutting on a top end of the pushing member and a second end. The pressing member is mounted rotatably on the housing and has multiple positioning recesses engaged selectively with the second end of the lever. The rotating knob is mounted on the housing. The micro switch is electrically connected with the air pump.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An inflating device comprising:
 a housing having
 a first air port; 
 a first check valve mounted in the first air port; and 
 a second air port; 
   a first air pump mounted in the housing and having a third air port communicating with the first air port; and   a first control device mounted in the housing and having
 a casing having an inner space; 
 a thin film mounted in the inner space of the casing to divide the inner space into a first chamber and a second chamber being free from communicating with the first chamber, wherein the second chamber communicates with the second air port; 
 a pushing member mounted in the first chamber and having a bottom end abutting against the thin film and a top end extending out of the casing; 
 a lever mounted pivotally on an inner surface of the housing and having a first end and a second end, the first end abutting on the top end of the pushing member; 
 a pressing member mounted rotatably on the housing and having a bottom provided with multiple positioning recesses engaged selectively with the second end of the lever; 
 a rotating knob mounted on and exposed from the housing; and 
 a micro switch mounted on the housing and electrically connected with the air pump. 
   
     
     
         2 . The inflating device as claimed in  claim 1 , wherein the housing further comprises a pivotal member mounted on the inner surface of the housing and pivotally connected with the lever. 
     
     
         3 . The inflating device as claimed in  claim 1 , wherein the first control device further comprises a torsion spring connected with the rotating knob. 
     
     
         4 . The inflating device as claimed in  claim 1  further comprising a second air pump mounted in the housing, wherein
 the housing further has a fourth air port and a second check valve mounted in the fourth air port; and 
 the second air pump has a fifth air port communicating with the fourth air port. 
 
     
     
         5 . The inflating device as claimed in  claim 4  further comprising a second control device mounted in the housing to control the second air pump.
