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.

Description

FIELD OF INVENTION [0001] The present invention provides an inflate and deflate air pump used for an air mattress. This adjustable inflate and deflate air pump is especially suitable for an air mattress at home and at sport places. It is an environmentally friendly light industry product. BACKGROUND OF THE INVENTION [0002] There are many kinds of mattresses used in daily life, such as a sponge mattress and an air mattress. The air mattress is widely used at home and sports places due to the advantages of being aesthetically pleasing, practicality of use and low cost. An air mattress needs a pump for inflation and deflation. There is a kind of pump with an automatic valve switch (see China Patent No. ZL01240604.x). The output hole of the valve of such a pump is closed immediately by an automatic switch device after the air mattress is inflated and this prevents the air from leaking out of the mattress. This kind of valve must be operated manually by inflating and deflating. Also, the...

Benefits of technology

[0003] The present invention provides an adjustable inflate and deflate pump. The pump body consists of two parts: the air storage compartment and the motor compartment. Both input and output air will flow through the motor compartment and thus cool the motor during operation. This design makes the pump easy to operate, protects the motor from overheating and becoming damaged, and makes the pump robust.

[0008] Compared to conventional pumps, the present invention is easy to operate, easy to inflate and deflate, secure, and solves the problem of the motor overheating and being damaged during the inflating and deflating process. It is low cost, convenient and durable.

Problems solved by technology

It is therefore troublesome to operate.

There is another kind of automatic inflate and deflate pump where the motor easily overheats and is damaged by long inflation time and frequent operation.
