A liquid replenishing mechanism and a water gun include a housing, a conductive component, a conveying component, and a liquid storage component. The housing includes a first outer surface. The conductive component is exposed outside the first outer surface and is electrically connected with the conveying component. The conveying component defines a liquid inlet end extended to the first outer surface and communicated with an outside of the housing and a liquid outlet end. The liquid storage component includes a liquid storage cavity communicated with the liquid outlet end. The conductive component is driven by the first outer surface to contact with liquid or moved away from the liquid. The conveying component is electrically connected with a power supply through the liquid. The liquid is input through the liquid inlet end and is output to the liquid storage cavity through the liquid outlet end.

A portable electronic device that selectively deploys a liquid incapacitating chemical agent is described. During operation, the portable electronic device receives or provides a trigger signal. For example, the portable electronic device may include a trigger (such as a mechanical or an electronic trigger), and the portable electronic device may provide the trigger signal when the trigger is activated. Alternatively or additionally, the portable electronic device may provide the trigger signal when an individual is detected in proximity or may receive the trigger signal via wireless communication. In response to the trigger signal, a control circuit provides a control signal to a pump. Then, based at least in part on the control signal, the pump transfers the liquid incapacitating chemical agent from a reservoir to a nozzle. Next, the nozzle discharges the liquid incapacitating chemical agent, e.g., in a stream, where the stream is external to the portable electronic device.

A device (100) for firing a projectile at a target body, in particular a fluid projectile or solid projectile, comprises a hand-held unit (100) for firing the projectile, the hand-held unit (100) comprises a propulsion drive (114) for accelerating the projectile and a distance measuring device (112) for measuring a distance between the hand-held unit (100) and the target body. The device (100) also comprises an energy store (120) for operating the propulsion drive (114), the propulsion drive (114) comprising a control unit (115), whereby the propulsion (114) is controllable in dependence on the distance measured.

The present invention relates to a non-lethal system for readily deploying a non-lethal weapon measure including a hand held firearm including a frame, and a slide, a dispersing container accommodated by the hand held firearm, at least one agent situated in the dispersing container, an actuator attached to or integrally formed with the hand held firearm, and wherein the dispersing container is responsive to the actuator being activated.

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 invention relates to an apparatus for shooting a projectile at a target body, in particular a fluid projectile or solid projectile, which apparatus comprises a hand-held device for shooting the projectile, wherein the hand-held device comprises a drive for accelerating the projectile and a distance-measuring device for measuring a distance between the hand-held device and the target body. The apparatus also comprises a stored energy source for operating the drive, wherein the drive comprises a control unit, by means of which the drive can be controlled in accordance with the measured distance.
