DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 1 and 2 , the electric firing controller for a lacquer bullet gun of the present invention in a first embodiment comprises: a power circuit 10 ; a lighting circuit 20 connected in parallel; a single triggering switch SW 2 for single firing; a closing circuit 30 , having a capacitor C 1 ; and an electromagnetic valve 40 or an electromagnetic device 50 , connected with the closing circuit 30 via a normally open terminal N 02 at the single triggering switch SW 2 .

The power circuit 10 has a battery B 1 and a power switch SW 1 which are connected in series. The power switch SW 1 serves to turn power on and off.

The lighting circuit 20 has a light emitting diode LED connected in series with a resistor R 1 , indicating a power-on state.

The single triggering switch SW 2 is a fine-controlled switch, connecting and disconnecting a common terminal C with a normally closed terminal NC 2 and the normally open terminal N 02 . The common terminal C is connected with the capacitor C 1 . The normally closed terminal NC 2 is connected with the switch SW 1 . The normally open terminal N 02 is connected with the electromagnetic valve 40 or with the electromagnetic device 50 . According to which state the switch SW 2 is in, the capacitor C 1 is either charged or discharged. When the single triggering switch SW 2 has the normally closed terminal NC 2 closed, the capacitor C 1 is charged, and when the single triggering switch SW 2 has the normally open terminal N 02 closed, the capacitor C 1 is discharged. Then the capacitor C 1 is connected with the electromagnetic valve 40 or with the electromagnetic device 50 , and electric charge is sent through the electromagnetic valve 40 or the electromagnetic device 50 , triggering outflow of high-pressure gas, so that a lacquer bullet is fired.

A reverse-oriented diode D 1 is connected in parallel with the electromagnetic valve 40 or with the electromagnetic device 50 as a protection against voltage peaks.

Using the electromagnetic valve 40 provides a greatly simplified structure, as compared to a conventional mechanical device with many structural parts.

Using the electromagnetic device 50 provides a structure that is easily made by converting a conventional lacquer gun, resulting in an economical effect.

Referring to FIG. 2 , the present invention in a second embodiment comprises: a power circuit 10 ; a lighting circuit 20 connected in parallel; a pulse generator 60 , connected with and controlled by a automatic triggering switch SW 3 ; a relay 70 , controlled by the pulse generator 60 ; a closing circuit 30 , having a capacitor C 1 and a normally closed control terminal NC 4 of the relay 70 ; and an electromagnetic valve 40 or an electromagnetic device 50 , connected with the closing circuit 30 via a normally open control terminal N 04 of the relay 70 .

The automatic triggering switch SW 3 is inserted between the lighting circuit 20 and the pulse generator 60 , being normally open to save power.

When the automatic triggering switch SW 3 is operated, a normally open terminal N 03 is closed, and electric voltage reaches the closing circuit 30 with the capacitor C 1 , having passed the normally closed control terminal NC 4 of the relay 70 , so that the capacitor C 1 is swiftly charged. At the same time, voltage reaches the pulse generator 60 , which generates a wave of 8 to 9 pulses per second, operating the relay 70 . The relay 70 subsequently causes switching between the normally closed and open control terminals NC 4 , N 04 . Each time the capacitor C 1 is connected with the normally open control terminal N 04 , the capacitor C 1 is discharged. Thus electric charge is sent through the electromagnetic valve 40 or the electromagnetic device 50 in an automatic sequence, triggering automatic outflow of high-pressure gas, so that lacquer bullet are fired automatically. While a user keeps the switch SW 3 pressed, automatic firing of lacquer bullets is done.

Referring to FIG. 3 , the present invention in a third embodiment provides for single firing and automatic firing. Therein, a mode selection switch SW 5 is placed in front of the automatic triggering switch SW 3 . The mode selection switch SW 5 has a normally open terminal N 05 which is connected with the automatic triggering switch SW 3 and a normally closed terminal NC 5 which is connected with the single triggering switch SW 2 . The capacitor C 1 and the electromagnetic valve 40 or electromagnetic device 50 are the same as in the first embodiment of the present invention, shown in FIG. 1 .

In a normal state of the present invention, the mode selection switch SW 5 is set to have firing controlled by the single triggering switch SW 2 . When the power switch SWl is operated to turn on power, electric current, passes through the normally closed terminal NC 2 , charging the capacitor C 1 , as in the first embodiment of the present invention, shown in FIG. 1 . As soon as the single triggering switch SW 2 is operated, the normally open terminal N 02 thereof is closed, and the capacitor C 1 is discharged. Then electric charge is sent through the electromagnetic valve 40 or the electromagnetic device 50 . Thus discharging of the capacitor C 1 causes outflow of high-pressure gas, so that a single lacquer bullet is fired.

When, on the other hand, the mode selection switch SW 5 is switched to the normally open terminal N 05 , no voltage reaches the single triggering switch SW 2 . Control of firing is no longer done by the single triggering switch SW 2 , but by the automatic triggering switch SW 3 . Then, automatic firing is performed, as already explained for the second embodiment of the present invention, shown in FIG. 2 .

Referring now to FIG. 4 , in a fourth embodiment of the present invention, the normally closed terminal NC 3 of the automatic triggering switch SW 3 of the second embodiment is connected with the single triggering switch SW 2 . The capacitor C 1 and the electromagnetic valve 40 or electromagnetic device 50 are the same as in the first embodiment of the present invention, shown in FIG. 1 .

In a normal state of the present invention, firing is controlled by the single triggering switch SW 2 , and operation is as already explained for the first and third embodiments.

When, on the other hand, the automatic triggering switch SW 3 is switched to the normally open terminal N 03 , the single triggering switch is disconnected from electric voltage, which is then led through the normally open terminal N 03 . Then, automatic firing is performed, as already explained for the second and third embodiments.

While the invention has been described with reference to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention which is defined by the appended claims.
