Air pump

Abstract

An air pump comprises a hollow pump body, at least one pulling member, an air inlet and an air outlet. The hollow pump body has air inside and consist of flexible sides and two opposite stiff ends. The air outlet is provided on the pump body to discharge the air in the pump body when the pump body is pressed. The pulling member is attached to one of the stiff ends of the pump body in order to restore the pressed pump body by pulling the pulling member. The air inlet is provided on the pump body to suck outside air into the pump body when the stiff end is pulled by the pulling member to restore the shape of the pressed pump body.

       at least one pulling member attached to the first stiff  end of the pump body in order to restore the shape of the pressed pump body by pulling the pulling member; and  
       an air inlet provided on the pump body to suck outside air into the pump body when the first stiff  end is pulled by the pulling member to restore the pressed pump body shape; wherein:  
       the pump body is received in the inflatable body and the pulling member is kept outside an inflatable body; and  
       a weight movably provided between the first stiff  end and the second stiff  end.  
     
     
       3. An air pump for inflating an inflatable product, the air pump comprising: 
       a hollow pump body having an interior and an exterior;  
       the pump body having air located in the interior;  
       the pump body including flexible sides, a first stiff  end and a second stiff  end opposite to the first stiff  end;  
       an air outlet provided on the pump body to discharge the air in the interior when the pump body is pressed;  
       at least one pulling member attached to the first stiff  end of the pump body in order to restore the shape of the pressed pump body by pulling the pulling member; and  
       an air inlet provided on the pump body to suck outside air into the pump body when the first stiff  end is pulled by the pulling member to restore the pressed pump body shape; wherein:  
       the pump body is firmly  received in an inflatable body;  
       the pulling member is kept outside the  an inflatable body; and  
       a ring weight movably provided around the pump body.  
     
     
       4. An air pump for inflating an inflatable product, the air pump comprising: 
       a hollow pump body having an interior and an exterior;  
       the pump body having air located in the interior;  
       the pump body including flexible sides, a first stiff end and a second stiff end opposite to the first stiff end;  
       an air outlet provided on the pump body to discharge the air in the interior when the pump body is pressed;  
       at least one pulling member attached to the first stiff end of the pump body in order to restore the shape of the pressed pump body by pulling the pulling member; and  
       an air inlet provided on the pump body to suck outside air into the pump body when the first stiff end is pulled by the pulling member to restore the pressed pump body shape; wherein:  
       the air pump has two pulling members respectively attached to the first and second stiff ends;  
       the pump body is firmly  received in an inflatable body; and  
       the pulling members are kept outside the  an inflatable body.  
     
     
       5. An air pump for inflating an inflatable product, the air pump comprising: 
       a hollow pump body having and interior and an exterior and having air located in the interior and including flexible sides, a first stiff end and a second stiff end opposite to the first stiff end;  
       an air outlet provided on the pump body to discharge the air in the interior when the first and second stiff ends are pressed to flatten the pump body; and  
       an air inlet provided on the pump body to suck outside air into the pump body; when the first and second stiff ends are pulled to restore the shape of the pump body;  
       said air pump being mounted inside the inflatable body of an inflatable product;  
       the first end of the air pump is curved and received in the inflatable body; and  
       at least one air hole being provided in the first curved end of the air pump in order to allow air in the inflatable body to flow back to the air pump.  
     
     
       6. An air pump for inflating an inflatable product, the air pump comprising: 
       a hollow pump body having and interior and an exterior and having air located in the interior and including flexible sides, a first stiff end and a second stiff end opposite to the first stiff end;
