A water gun is provided. On the water gun, when a liquid pump is turned on, liquid in a liquid storage device is injected into a first water tank through a water inlet hole. The liquid pump is used as a unique power source to synchronously perform two functions: In a first function, the liquid in the first water tank is extracted through the water outlet hole for being pressurized, thus forming a high-pressure jet water flow. In a second function, a dynamic pressure field is built inside the first water tank to force a part of the liquid to flow towards a second water tank through a water replenishment hole. The single-pump double-output design directly replaces a shooting water pump and a mist spray water pump that work independently in a traditional double-pump system, and fundamentally reduces power consumption.

A toy water gun comprises a handle, a frame comprising a barrel, and a pressurized mechanism. The handle comprises a grip and a trigger. The frame comprises at a first end, a quick-connect system for attaching to one or more external accessories thereto; at a second end opposite the first end, a fluidic output that is capable of delivering water from the barrel to the atmosphere; at a top surface, an aperture for allowing water into an internal fluidic cavity within said frame, said internal fluidic cavity being fluidly connected to said barrel; and at a lower surface, a water cartridge seat that allows for external attachments to be secured thereto. The pressurized mechanism for delivering water from the internal fluidic cavity, and through the barrel so that the water can exit the toy water gun when the trigger is pulled.
