Abstract:
1. A paintball feeding device of a paintball marker gun, comprising (a) a signal transmitter held in a pistol grip of a main body of a paintball marker gun; the signal transmitter being electrically connected to a controller held in the pistol grip; the signal transmitter including: a voltage regulator; an encoder connected to the voltage regulator; an oscillator connected to the encoder; and an antenna connected to the oscillator; when the signal transmitter receives a signal indicating that power source is turned on, the signal being going to be voltage-regulated by means of the voltage regulator, encoded by means of the encoder, sent through the oscillator, and transmitted through the antenna; (b) a signal receiver; the signal receiver including an antenna, an amplifier, and a demodulating circuit; and (c) a paintball feeding unit containing paintballs and joined to the main body of the paintball marker gun; the paintball feeding unit being electrically connected to the signal receiver; the paintball feeding unit including a control circuit board, and a stepping motor; the control circuit board having a driver fitted thereon, which is electrically connected to the stepping motor; the control circuit board having a limiter fitted thereon; the control circuit board having a microcontroller fitted thereon, which has decoding function; both the driver and the limiter being connected to the microcontroller; the control circuit board having a current-sensing device fitted thereon, which is electrically connected to both the limiter and the stepping motor; when the trigger is pressed to shoot a paintball, the signal transmitter being going to transmit a signal immediately, which will be received through the antenna of the signal receiver, amplified through the amplifier, and sent to the microcontroller through the modulating circuit such that the stepping motor of the paintball feeding unit will start rotating so as to feed a paintball to the main body of the paintball marker gun, thus making shooting and feeding of paintballs happen in a synchronized manner.
