FIG. 1 is a perspective view of a portable electronic air compressor in accordance with the preferred embodiment of the present invention; -
FIG. 2 is a partially perspective view of the portable electronic air compressor as shown inFIG. 1 ; -
FIG. 3 is a plan view of the portable electronic air compressor as shown inFIG. 1 ; -
FIG. 4 is a plan cross-sectional view of the portable electronic air compressor as shown inFIG. 1 ; -
FIG. 5 is a circuit layout of a control circuit of the portable electronic air compressor as shown inFIG. 1 ; and -
FIG. 6 is a perspective view of a portable electronic air compressor in accordance with another embodiment of the present invention. - Referring to the drawings and initially to
FIGS. 1-5 , a portable electronic air compressor in accordance with the preferred embodiment of the present invention comprises ahousing 10, and amain body 20 mounted in thehousing 10. - The
housing 10 includes abase 11 for supporting themain body 20, and acover 12 pivotally mounted on thebase 11 to encompass themain body 20. - The
main body 20 includes aminiature motor 30, areduction device 40 mounted on themotor 30 and including adrive gear 41 mounted on and rotated by arotation shaft 32 of themotor 30 and a drivengear 42 meshing with thedrive gear 41, an actuatingdevice 50 mounted on thereduction device 40 and including acrank shaft 51 mounted on and driven by the drivengear 42 of thereduction device 40 and apiston 52 mounted on and driven by thecrank shaft 51, anair storage device 60 connected to thepiston 52, anelectronic control circuit 70 connected to themotor 30 for driving themotor 30 to rotate, and a direct current (DC)air supply 72 connected to thecontrol circuit 70 to supply an electric power to thecontrol circuit 70. The drivengear 42 of thereduction device 40 has a tooth number greater than that of thedrive gear 41 of thereduction device 40. - In such a manner, when the
piston 52 is moved to the downward stroke, the air inlet (not shown) is opened to draw the air inward, and when thepiston 52 is moved to the upward stroke, the air inlet is closed. At this time, thepiston 52 is moved upward to compress the air, and the compressed air is introduced into and stored in theair storage device 60. Theair storage device 60 is connected to anair outlet pipe 61 to introduce the compressed air at a high pressure outward for use. - The total output power of the air compressor is decreased due to the direct current (DC)
air supply 72. Thus, thereduction device 40 includes adrive gear 41 having a smaller tooth number to drive the drivengear 42 having a greater tooth number, to enhance the operation torque of thepiston 52, so as to produce the compressed air required for operation of the pneumatic tool (not shown). - In addition, the compressed air of different pressure is required for the pneumatic tools of different kinds. Thus, the
main body 20 further includes apressure regulating device 80 mounted between anair inlet pipe 62 of themain body 20 and thepiston 52 to regulate the pressure contained in theair storage device 60 to prevent theair storage device 60 from being broken due to an excessive pressure. - Further, when the compressed air is directly drained outward from the
air outlet pipe 61, the pneumatic tool cannot be operated smoothly due to the uneven pressure of the compressed air. Thus, theair storage device 60 is used to stabilize the pressure of the compressed air, so that the pneumatic tool can be operated smoothly. - As shown in
FIG. 5 , thecontrol circuit 70 is used to detect the pressure contained in theair storage device 60 and to control operation of themotor 30 according to the detected pressure values of theair storage device 60. - In practice, after the
switch 720 of the directcurrent air supply 72 is triggered, thecontrol circuit 70 includes a firstpressure detection unit 73 to detect the pressure contained in theair storage device 60. When the pressure contained in theair storage device 60 is smaller than 60psi, themotor 30 is operated to drive thepiston 52 to produce the compressed air having a predetermined pressure. When the pressure contained in theair storage device 60 is greater than 140psi, themotor 30 stops operating, and anormal lamp 75 of thecontrol circuit 70 lights to indicate the normal state. - In addition, the
control circuit 70 further includes a secondpressure detection unit 74 to detect the pressure contained in theair storage device 60. When the pressure contained in theair storage device 60 is greater than 160psi, an over-pressurewarning lamp 76 of thecontrol circuit 70 lights to warn the user that the pressure contained in theair storage device 60 is too large, so that the user can operate thepressure regulating device 80 to regulate the pressure contained in theair storage device 60 so as to release the pressure manually until the pressure contained in theair storage device 60 achieves the safety value. After the secondpressure detection unit 74 have detected the pressure contained in theair storage device 60 more than three times, the pressure contained in theair storage device 60 is still greater than 160psi, thecontrol circuit 70 will lock the air compressor automatically, so that the air compressor stops operating. At this time, alocking lamp 77 of thecontrol circuit 70 lights to indicate the locked state. Thus, the air compressor proceeds to operate after the user releases the pressure manually so as to protect the user's safety. - On the other hand, the
control circuit 70 further includes avoltage detection unit 78 to detect the electric power of the directcurrent air supply 72. When thevoltage detection unit 78 detects that the voltage of the directcurrent air supply 72 is smaller than a predetermined voltage, anindication lamp 79 of thecontrol circuit 70 lights to notify the user to replace the directcurrent air supply 72. - As shown in
FIG. 6 , the air compressor further comprises ahandle 90 mounted on thebase 11 of thehousing 10, so that the air compressor is portable. - Accordingly, the volume of the
main body 20 of the air compressor is greatly reduced by provision of the directcurrent air supply 72, theminiature motor 30, thereduction device 40 and thecontrol circuit 70, so that the air compressor occupies a smaller space. In addition, the air compressor is made portable, thereby facilitating the user carrying the air compressor. Further, thecontrol circuit 70 is used to exactly detect the pressure contained in theair storage device 60 and to control operation of themotor 30 according to the detected pressure values of theair storage device 60. Further, thecontrol circuit 70 includes a firstpressure detection unit 73 and a secondpressure detection unit 74 to doubly detect the pressure contained in theair storage device 60 so as to assure the safety of theair storage device 60. Further, the air compressor is provided with the directcurrent air supply 72, so that the air compressor is available for any place and position, thereby enhancing the versatility of the air compressor. Further, the reduction device includes a drive gear having a smaller tooth number to drive the driven gear having a greater tooth number to enhance the operation torque of the piston, so as to produce the compressed air required for operation of the pneumatic tool. Further, the 9 pressure regulating device is used to regulate the pressure contained in the air storage device to prevent the air storage device from being broken due to an excessive pressure. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
