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.

1 . A hydraulic stun gun, comprising a housing, two water tanks mounted in said housing, two metal nozzles provided at a front side of said housing, two water tubes respectively connected between said water tanks and said metal nozzles, a first battery set, a voltage converter adapted for converting DC battery power of said first battery set into a high voltage, two lead wires electrically connecting positive and negative terminals of said first battery set and said voltage converter to said metal nozzles, a micro switch electrically connected between said two lead wires and said first battery set, a high pressure air source mounted in said housing and adapted for providing a compressed air pressure into said water tanks to force water out of said water tanks into said water tubes, a button operable to switch on/off said micro switch and said high pressure air source,
 Wherein: two needle valves are respectively mounted in said water tubes and operable to close/open said water tubes, each said needle valve comprising a valve hole and a valve needle movable with said button to close/open said valve hole.   
     
     
         2 . The hydraulic stun gun as claimed in  claim 1 , wherein said button comprises a slide fixedly connected thereto, said slide having two rod members respectively coupled to the valve needles of said needle valve for enabling the valve needles of said needle valves to be moved with said button to close/open the respective valve holes. 
     
     
         3 . The hydraulic stun gun as claimed in  claim 2 , wherein said high pressure air source is a piston set, said piston set having one end connected to said two water tanks through an air tube, said air tube having mounted therein a check valve to prevent reverse flow of air. 
     
     
         4 . The hydraulic stun gun as claimed in  claim 3 , further comprising a compression spring connected between said check valve and said slide of said button. 
     
     
         5 . The hydraulic stun gun as claimed in  claim 4 , wherein said high pressure air source is a high-pressure air container controllable to provide a compressed air pressure to said water tanks to force water out of said water tanks into said water tubes. 
     
     
         6 . The hydraulic stun gun as claimed in  claim 4 , further comprising a voltage regulator for regulating the output high voltage of said voltage converter. 
     
     
         7 . The hydraulic stun gun as claimed in  claim 4 , wherein said high pressure air source comprises a power air pump mounted in said housing and a second battery set mounted in said housing and electrically connected to said power air pump for causing said power air pump to pump compressed air into said water tanks. 
     
     
         8 . The hydraulic stun gun as claimed in  claim 4 , wherein said high pressure air source comprises a power air pump mounted in said housing and electrically connected to said first battery set through said micro switch and controllable by said button to pump compressed air into said water tanks.
