US12590780 - Air gun with onboard electric pump

The patent describes an air gun featuring an onboard electric pump assembly that utilizes a high-speed DC motor and a user-operable controller to manage air pressure. This assembly includes a multi-stage air pumping system designed to sequentially increase air pressure to a predetermined level, with integrated pressure monitoring for optimal performance.
Claim 1
1 . An onboard electric pump assembly for an air gun, comprising: a DC motor powered by a battery; a controller that is operable by a user through a user interface, wherein the controller is configured to control the DC motor; a mounting structure to mount the DC motor within the air gun; and a multi-stage air pumping assembly configured to sequentially increase air pressure in multiple stages to a predetermined level before charging an air tube assembly of the air gun, wherein the controller is connected to a pressure monitor system, and the pressure monitor system is configured to: monitor pressure in the multi-stage air pumping assembly; and monitor pressure in the air tube assembly, wherein the controller is further configured to control the multi-stage air pumping assembly based on the monitored pressure in the multi-stage air pumping assembly and the air tube assembly. a DC motor powered by a battery; a controller that is operable by a user through a user interface, wherein the controller is configured to control the DC motor; a mounting structure to mount the DC motor within the air gun; and a multi-stage air pumping assembly configured to sequentially increase air pressure in multiple stages to a predetermined level before charging an air tube assembly of the air gun, wherein the controller is connected to a pressure monitor system, and the pressure monitor system is configured to: monitor pressure in the multi-stage air pumping assembly; and monitor pressure in the air tube assembly, wherein the controller is further configured to control the multi-stage air pumping assembly based on the monitored pressure in the multi-stage air pumping assembly and the air tube assembly.
