Air pump

Abstract

An air pump includes a mount member having a main body and a chamber. An air bag set has a substrate, two air bags, each of which have an air chamber and a linking portion. An insulating plate has a plate member, two inlets and two outlets communicated with the air chambers of the air bags respectively. A ventilation part has a pad member, two inlet valves and two outlet valves, both of which are communicated with the inlets and the outlets of the insulating plate respectively. An air guide device has a main member, two inlets and two outlets, both of which are communicated with the inlet and outlet valves of the ventilation part respectively. A linking assembly has rotary base and a linking portion connected to the linking portion of the air bag set.

1 . An air pump, which is driven by a spindle of a motor, comprising: 
 a mount member having a main body and a chamber;    an air bag set having a substrate, an air bag provided on said substrate, in which an air chamber is formed, wherein said air bag has a bag bladder and a linking portion;    an insulating plate having a plate member, an inlet and an outlet, wherein said inlet and said outlet are communicated with said air chamber of said air bag set;    a ventilation part having a pad member, an inlet valve and an outlet valve, wherein said inlet valve is communicated with said inlet of said insulating plate and said outlet valve is communicated with said outlet of said insulating plate;    an air guide device having a main member, an inlet and an outlet, wherein said inlet is communicated with said inlet valve of said ventilation part and said outlet is communicated with said outlet valve of said ventilation part, and    a linking assembly having rotary base driven by said spindle of said motor for rotation and a linking portion connected to said linking portion of said air bag of said air bag set.    
   
   
       2 . The air pump as defined in  claim 1 , wherein said mount member has a first mount and a second mount assembled together.  
   
   
       3 . The air pump as defined in  claim 1 , wherein said mount member has a surrounding member to receive said bag bladder of said air bag of said air bag set therein.  
   
   
       4 . The air pump as defined in  claim 1 , wherein said pad member of said ventilation part has a sealing rib surrounding and isolating said inlet valve and said outlet valve.  
   
   
       5 . The air pump as defined in  claim 1 , wherein said air guide device further has an air pipe communicated to said outlet of said air guide device.  
   
   
       6 . The air pump as defined in  claim 1 , wherein said linking assembly further has an bag linking device pivoted on said rotary base and said linking portion is provided on said bag linking device.  
   
   
       7 . The air pump as defined in  claim 1 , wherein said mount member has a positioning recess and said air bag set has a positioning plate to be received in said positioning recess of said mount member.  
   
   
       8 . The air pump as defined in  claim 1 , wherein the quality of air bag of said air bag set is two.
