AIR COMPRESSOR
An improved air compressor generally includes a cylinder fitted with a piston body, a main frame for mounting a motor, and an air storage container. The cylinder defines at its top wall a plurality of exit holes, which are separated by a plurality of blocking walls and regulated by a control mechanism. When the compressed air is produced in the cylinder causing the control mechanism to open the exit holes, the instantaneous high-pressure air that flows through the exit holes can be restrained by the blocking walls to prevent the air from interfering with operation of the control mechanism, so that the piston body can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.
The present invention relates to an air compressor and, more particularly, to an improved air compressor, wherein a cylinder thereof is fitted with a piston body and defines a plurality of exit holes at its top wall and is provided at its top wall with a plurality of air blocking walls, which can isolate the exit holes from each other at a certain extent, and the exit holes are regulated by a control mechanism to be opened or closed, whereby the piston body can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.
DESCRIPTION OF THE PRIOR ARTGenerally, an air compressor has a cylinder which allows a piston body to conduct reciprocating motion therein to produce compressed air which can overcome a valve mechanism, so that the compressed air can flow through an exit hole of the cylinder to enter the inner space of an air storage container or an air tank. The air storage container is provided with outlets for delivering the compressed air to an object to be inflated.
In conventional air compressors, there is only one exit hole defined at the cylinder for outputting the compressed air into the air storage container. The exit hole of the cylinder is controlled by a valve mechanism, which generally includes a plug and a compression spring, so that the exit hole can be opened or closed properly according to the pressure of the compressed air. In operation, the compressed air produced in the cylinder can overcome the compressive force of the compression spring to enter the inner space of the air compressor. However, the compressed air stored in the air storage container can exert a back force on the plug, thus restraining the plug from being moved away from the exit hole. As a result, the piston body, which conducts reciprocating motion in relation to the cylinder, will be subjected to greater resistance. Therefore, the piston body may not move smoothly in relation to the cylinder, and thus the speed of inflating an object may decrease. Furthermore, the motor of the air compressor may become too hot, thus decreasing the performance of the motor. Even worse, the motor may be under the risk of burning out.
In view of the foregoing, the applicant intends to develop an improved air compressor which can solve the shortcomings of conventional air compressors.
SUMMARY OF THE INVENTIONOne object of the present invention is to provide an air compressor, wherein a cylinder thereof is fitted with a piston body and defines at its top wall a plurality of exit holes and is provided at its top wall with a plurality of air blocking walls, which isolate the exit holes from each other at a certain extent, and the exit holes are regulated by a control mechanism to be opened or closed, whereby when the compressed air is produced in the cylinder causing the control mechanism to open the exit holes, the instantaneous high-pressure air that flows through the exit holes can be restrained by the air blocking walls to prevent the air from interfering with operation of the control mechanism, so that the piston body can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.
According to one aspect of the present invention, since the cylinder defines a plurality of exit holes, a large amount of compressed air produced, through reciprocating motion of the piston body, in the cylinder may enter an air storage container in a short time. Since the compressed air can quickly enter the air storage container, the piston body can conduct reciprocating motion more smoothly and thus the performance of the air compressor and the speed of inflating an object can be increased.
Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

As a summary, the air compressor of the present invention has a breakthrough over the prior art in that the top wall 21 of the cylinder 2 defines a plurality of exit holes 4, 5, 6 and is provided with a plurality of air blocking walls 41, 51, 61 around the exit holes, and a plurality of plugs 7, 8, 9 are used to control the states (open or closed) of the exit holes, so that the compressed air produced in the cylinder 2 may quickly enter the inner space 36 of the air storage container 3. In addition, the air blocking walls 41, 51, 61 respectively confine the plugs 7, 8, 9 therein, thus isolating the exit holes 4, 5, 6 from each other at a certain extent, so that when the compressed air produced in the cylinder 2 pushes the plugs 7, 8, 9 up to open the exit holes 4, 5, 6, the instantaneous high-pressure air that flows through the exit holes 4, 5, 6 can be restrained by the air blocking walls 41, 51, 61, thus preventing the air from interfering with movements of the plugs 7, 8, 9, so that the piston body 14 can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased. These features render the air compressor of the present invention useful and inventive.
