Electronic pressurised fluid dispensing gun with automatic locking mechanism

An electronic pressure fluid dispensing gun comprising,

• a fluid inlet connection,
• a handle for easy handling,
• an electronic control interface for managing and entering the quantities of fluid to be dispensed,
• a wireless battery recharging system on the gun comprising a receiver, and a charging station,
• a manually operated trigger for opening and closing a control valve,
• a measuring chamber responsible for measuring a volume of fluid transferred and communicating the measured volume to an electronics module, wherein the measuring chamber is downstream of the control valve and outside a pressure line,
• an outlet connection to which a nozzle extension is attached to prevent a dripping of fluid and to direct a fluid flow to the outlet, and
• an automatic valve locking mechanism, located in a lower part of the gun, without interrupting flow of a fluid under pressure in such a way that a fluid inlet and a fluid outlet through the gun are on a longitudinal plane of the gun, and consisting of:
• the control valve, wherein the control valve is automatically closed by the locking mechanism when a quantity of fluid to be dispensed is reached, which prevents a dispensing of the fluid unless a new dispensing order is validated in the electronics module of the gun,
• a connecting rod,
• a slide,
• a first pin that connects the connecting rod to the slide,
• a second pin that connects the control valve to the connecting rod and that slides along a groove,
• a slide spring,
• a cam pawl,
• a torsion spring, and
• a solenoid having a stem which moves linearly by retracting and extending when receiving an electrical signal from the electronics module, and
• wherein the automatic valve locking mechanism also includes the manually operated trigger which actuates the connecting rod which is hinged at one end by the first pin which joins it to the slide which slides in a housing, wherein the slide is linked to the connecting rod, the slide contacts the cam pawl, which is kept in contact with the slide by the torsion spring, and will act independently of the stroke of the manually operated trigger, allowing the flow rate to be regulated without the need to lock the manually operated trigger in an extreme position.
