A liquid dispensing apparatus comprising a container portion, a receiver portion, and a grip portion. The container portion includes a first opening, a second opening, and a third opening. The first opening comprises a trap door valve. The second opening comprises a vent valve attached to a trigger located in the grip portion. The third opening is in liquid communication with a liquid ejection system.

A toy water gun includes a hand-held body having a water reservoir capable of storing a predetermined quantity of water therein, and a guide rail engaged with the water reservoir. The toy water gun further includes a hand-operated pump mechanism is in fluid communication with the water reservoir and dynamically engaged with the guide rail, a discharge nozzle in fluid communication with the water reservoir and having an illuminable water trajectory selectively egressed distally away therefrom, and a light emitting mechanism attached to a dynamic portion of the pump mechanism. Advantageously, the dynamic portion of the pump mechanism and the light emitting source are contemporaneously reciprocated along a bi-directional travel path relative to a position of the discharge nozzle and thereby illuminate the illuminable water trajectory after being egressed from the discharge nozzle.

The present application relates to a water storage and jetting structure of toy water gun, comprising a housing, a water storage tank, a push rod and a trigger mechanism, in which the front part of the push rod is located inside the water storage tank, wherein the water storage and jetting structure of toy water gun further comprises an electric water jetting mechanism for driving the push rod to push forward water jetting and a spring for pulling back the push rod to return; wherein all of the water storage tank, the electric water jetting mechanism, the trigger mechanism, the push rod and the spring are disposed inside the housing, and a trigger end of the trigger mechanism is electrically connected to a signal input end of the electric water jetting mechanism; and wherein the rear of the push rod engageably contacts with the spring.

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 invention is a weapon/protection system that generates two or more channels of physical medium in which travels an electric current. The current circulates though the channels due to their impedance being lower than that of air. From the generated electrical potential difference resulting at the target, the current can mildly shock, stun or fully paralyze a subject; therefore the device can be used as a weapon or deterrent for entry.

This system incorporates a novel means of converging physical medium onto a controlled point in space. The system may also incorporate methods that modify the medium's viscosity in order to increase the length of continuous laminar in the channel of a jet medium (the jet length without droplet formation or discontinuous breakdown). The aforementioned medium may also be heated gas.

A vortex ring producing gun includes a body defining a first interior volume. The vortex ring producing gun includes a movable nozzle coupled with the body, comprising at least one nozzle opening, and defining a second interior volume. The vortex ring producing gun includes one or more conduits providing fluid communication between said first interior volume and said second interior volume. The vortex ring producing gun includes an energy storage element configured to bias the movable nozzle in a first direction. The vortex ring producing gun includes a latching key configured to hold the movable nozzle in a retained position against the bias from the energy storage element. The vortex ring producing gun includes a movable cocking/firing element configured to interact with the body, the energy storage element, the latching key, and the movable nozzle to selectively cock or fire the vortex ring-producing gun.
