Automatic liquid dispensing gun

Abstract

Automatic liquid dispensing gun, comprising a structure provided with a connector for coupling to a pipe for feeding a liquid and with a nozzle designed to be inserted in a container designed to receive a dispensed liquid, the nozzle comprising a duct for dispensing the liquid which is controlled by an actuation handle and an air intake duct which reaches a device adapted to block the dispensing of the liquid when the inflow of air ceases, the gun further comprising an element that is sensitive to the passage of the liquid and is connected to a sensor which transmits signals to an electronic board capable of recording the dispensed quantity of liquid, with transmission of the data item related to the dispensed quantity to a display accommodated within the structure.

1 . An automatic liquid dispensing gun, comprising a structure provided with a connector for coupling to a pipe for feeding a liquid and with a nozzle designed to be inserted in a container designed to receive a dispensed liquid, said nozzle comprising a duct for dispensing the liquid which is controlled by an actuation handle and an air intake duct, which reaches a device adapted to block the dispensing of the liquid when the inflow of air ceases, the gun further comprising an element that is sensitive to the passage of the liquid and is connected to a sensor which transmits signals to an electronic board capable of recording the dispensed quantity of liquid, with transmission of the data item related to said quantity to a display accommodated within said structure. 
     
     
         2 . The automatic gun according to  claim 1 , further comprising means adapted to block the air intake duct, which are activated upon a command that arrives from the electronic board when a value of the quantity of liquid dispensed that is set by the user on said board is reached, consequently stopping the flow of the liquid dispensed by the gun. 
     
     
         3 . The automatic gun according to  claim 2 , wherein said means adapted to block the air intake duct comprise a flow control element, which is retained by the action of a spring in a position for opening the duct and is provided with a magnet designed to be operated by a fixed coil, which is arranged so as to wrap around said duct and is connected to the electronic board in order to provide a translational motion of said flow control element toward a position for closing the duct.
