Adjustable Inflate and Deflate Air Pump

Abstract

The present invention provides an adjustable inflate and deflate air pump consisting of: a pump frame, a pump body, a motor, blades, an air input hole, an air output hole, and a valve. A pump compartment of the present invention consists of an air compartment and a motor compartment. The air compartment is built up by the pump protective shield and the motor protective shield. The air compartment is connected to the air input hole. The motor compartment is built up by the motor protective shield and is connected with the air output hole at its bottom. On the upper part of the pump is a swing knob which is connected to the pump body. On the lower part of the pump is a curved surface. During its working process, the motor is cooled by constant airflows through the motor compartment during both inflation and deflation. Thus, the difficult problem of the motor overheating and being damaged during inflation and deflation has been solved perfectly. It is therefore a new pump with promising prospects.

1 . An adjustable inflate and deflate air pump, comprising of a pump frame, an upper deck, a swing knob, a motor, blades, air input and output holes, and a valve. The swing knob is mounted on the top of the pump, the motor is mounted in the middle of the pump body, there are blades fixed on the motor, in the lower part of the pump body there are air input and output holes. It is characterized that the pump compartment is divided into two parts: the air storage compartment and the motor compartment. The air storage compartment is built up by the pump protective shield ( 6 ) and motor protective shield ( 7 ), and it is connected to the air input hole ( 15 ). The air input hole ( 15 ), the motor protective shield ( 7 ), the pump protective shield ( 6 ) and the air output hole of the air storage compartment ( 18 ) belong to the air storage compartment. Motor compartment is built up by the motor protective shield ( 7 ), it is connected to the air output hole on the bottom and the air storage compartment on the top. The motor protective shield ( 7 ), motor ( 3 ), blades ( 16 ), air output hole belong to motor compartment.  
   
   
       2 . The adjustable inflate and deflate air pump of  claim 1 , further comprising a swing knob ( 4 ) on the top of the air pump, fixed on the upper part of the pump protective shield ( 6 ) and forms as part of the pump protective shield, by revolving the swing knob the pump body will be revolved accordingly, and the relative position of the air input and output holes at the bottom of the pump towards the valve will be changed accordingly.  
   
   
       3 . The adjustable inflate and deflate air pump of  claim 1 , further comprising of a curved surface ( 14 ) on the bottom of the pump protective shield ( 6 ), the spring rod ( 12 ) of valve ( 9 ) is placed onto the curved surface ( 14 ) of the pump body.  
   
   
       4 . The adjustable inflate and deflate air pump of  claim 1 , further comprising a valve ( 9 ) mounted on the side of the bottom of the pump frame ( 1 ), a spring rod ( 12 ) and a closing rubber ( 10 ) inside the valve ( 9 ), the closing rubber ( 10 ) connected with the rod ( 12 ), the rubber ( 10 ) will open or close the valve following the forwards and backwards move of the rod ( 12 ).  
   
   
       5 . The adjustable inflate and deflate air pump of  claim 1 , further comprising an upper deck ( 2 ) on the top of the pump frame ( 1 ), and the air hole ( 5 ) in the upper deck ( 2 ), the power switch and power line connection of the top of the pump frame.
