Hydraulic stun gun

Abstract

A hydraulic stun gun includes a housing holding two water tanks, two metal nozzles respectively connected to the water tanks through a respective water tube, two lead wires electrically connecting a battery set and a high voltage converter to the metal nozzles through a micro switch, a piston set for providing a compressed air pressure to the water tanks to force water out of the water tanks into the water tubes, two needle valves respectively mounted in the water tubes, a button operable to move open the needle valves and to switch on the micro switch for letting two jets of water be driven out of the metal nozzles and a high voltage low current be driven into the target through the two jets of water when the two jets of water touched the target.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to electrical discharge weapons and more particularly, to a hydraulic self-defense stun gun for disabling a target at a distance by discharging high voltage, low current into the target through two jets of water.[0003]2. Description of the Related Art[0004]A regular self-defense stun gun user must have the positive and negative electrodes of the stun touch the target so that electrical high voltage can be discharged into the target to disable the target. However, it is dangerous to approach to the target within a short distance. Therefore, hydraulic stun gun for disabling a person at a distance is developed. FIG. 1 illustrates a hydraulic stun gun according to the prior art (Taiwan Patent Publication Number 493735). According to this design, as shown in FIG. 1, the hydraulic stun gun comprises a housing 100 having installed therein two water tanks 10 (see FIG. 2), two metal nozzles 20, two ...

AI Technical Summary

Benefits of technology

"The present invention is a hydraulic stun gun that uses needle valves to control the output of jets of water positively, preventing a water leakage. The gun has a housing, two water tanks, two metal nozzles, two water tubes, a first battery set, a voltage converter, two lead wires, a micro switch, a high pressure air source, a button, and needle valves. The needle valves are mounted in the water tubes and can be opened or closed to control the output of water. The high pressure air source provides compressed air pressure to force water out of the water tanks into the water tubes. The button activates the micro switch to switch on / off the needle valves. The high pressure air source can be a piston set or a power air pump. The technical effect of this invention is to provide a reliable and efficient hydraulic stun gun that prevents water leakage and can be easily operated with a single button."

Problems solved by technology

However, it is dangerous to approach to the target within a short distance.

However, the aforesaid hydraulic stun gun is still not satisfactory in function.

The compression spring 602 may start to wear quickly with use.
