A configurable fluid vessel comprising a flexible bladder (45) having a fluid port (47) through which a fluid such as water can be provided into the bladder (45). The fluid vessel further comprises an internal support frame (43) within the flexible bladder (45) to increase rigidity and preferably an urging means (44) for urging the flexible bladder (45) into a predetermined shape. The fluid vessel is collapsible for storage whilst retaining rigidity when in use. The fluid vessel is particularly suited for use in explosive jet disruptors (40) for tailoring the formation of a fluid jet.

A liquid jet ejection device is provided. The liquid jet ejection device has a flexible lumen having an intake end positioned to be in fluid communication with a liquid source, and an output end distal from the intake end. A pump is coupled to the flexible lumen, the pump being actuatable to eject a liquid from the liquid source via the output end. A body structure extends from a handle and supports the output end of the flexible lumen, the body structure having a base form in which the output end of the flexible lumen is supported in a base pose relative to the handle, the body structure being deformable from the base form via contact with an object, the body structure returning to the base form upon withdrawal of contact.

The present invention provides a novel toy electric water pistol. The novel toy electric water pistol adopts a water suction sensing part with double sensing contacts to cooperate with a first motor in a linkage manner, so that the toy electric water pistol can be automatically and quickly processed for water suction and replenishment, without manual water addition operation, so that it is convenient to use and has high water storage efficiency. At the same time, by setting a quantitative driving jetting part, it can realize the sequential quantitative water jet jetting operation with a high response speed. The toy electric water pistol has more sufficient jetting power and a longer jetting range by combining a water jet with a conical water jet hole.

Apparatus and associated methods relate to a continuously operable water gun. In an illustrative example, the continuously operable water gun may include a housing configured to receive a pool noodle extending along a longitudinal axis. The continuously operable water gun may, for example, be integrated into wearable technology to allow other forms of use, such as wrist mounted for ease of mobility. Various embodiments may advantageously include a housing that defines a discharge conduit and an intake conduit both fluidly coupled to the water pump configured such that the intake conduit may be submerged below a surface of water to receive water and the discharge conduit may disperse water along an axis of firing. The pool noodle may be configured to be received along the longitudinal axis of the housing.

An anti-freeze water gun structure has a gun body. The gun body has a water passageway therein, a water inlet at a lower end thereof, and a water chamber between the water passageway and the water inlet. A guide tube is provided in the water chamber. A slidable piston is fitted onto the guide tube. A lower end of the guide tube has a sealing structure for blocking a lower end of the water chamber. A lower half of the water chamber, located below the piston, is surrounded by the piston, an inner wall of the water chamber, an outer wall of the guide tube and the sealing structure to form a closed chamber. An elastic member is provided in the closed chamber for elastically pushing the piston upward. A water channel communicating with the water inlet and the water passageway is formed in the guide tube.

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.
