## Abstract

The present disclosure provides a portable lachrymatory and electrical device. The portable lachrymatory and electrical device includes a fluid reservoir containing a lachrymatory composition, and a pump in fluid communication with the fluid reservoir and an orifice. The orifice is operable to emit a fluid stream trajectory of the lachrymatory composition there-through. The portable lachrymatory and electrical device also includes two terminals operable to deliver an electric potential between the two terminals.

## Claims

### Claim 1

A portable lachrymatory and electrical device comprising:
a housing comprising a wall;
a mechanical sight fixed to an exterior surface of the wall;
a rigid fluid reservoir comprising a lachrymatory composition, the rigid fluid reservoir releasably attached to the housing via a clip attachment arm that is spring loaded;
a pump fixed within the housing and in fluid communication with the rigid fluid reservoir and an orifice that is a converging orifice having a conical shape, the orifice operable to emit a fluid stream trajectory of the lachrymatory composition there-through,
a reservoir outlet tubing in fluid communication with the pump, the rigid fluid reservoir, a mechanical filter, and a seal assembly comprising a spring loaded check valve;
the pump operable to create a relative suction pressure in the rigid fluid reservoir with respect to ambient environment, which (i) draws lachrymatory composition through the mechanical filter into the reservoir outlet tubing, and then into the seal assembly, and then into the pump, and (ii) opens the spring loaded check valve, allowing air from ambient environment to enter the rigid fluid reservoir;
a motor for driving operation of the pump, the motor electrically connected to a rechargeable battery;
two terminals extending through the wall of the housing, the two terminals operable to deliver an electric potential between the two terminals, the two terminals having a horizontal configuration and the orifice positioned between the two terminals, wherein a peak electric potential between the two terminals is from 45,000 V to 55,000 V; and
a flashlight operable to emit a light through the wall, the flashlight oriented parallel to the fluid stream trajectory.

### Claim 2 (depends on 1)

The portable lachrymatory and electrical device of claim 1, wherein the lachrymatory composition comprises a lachrymatory agent, water and an additive.

### Claim 3 (depends on 1)

The portable lachrymatory and electrical device of claim 1, wherein the rigid fluid reservoir has a capacity to contain from 20 ml to 6,000 ml of the lachrymatory composition.

### Claim 4 (depends on 1)

The portable lachrymatory and electrical device of claim 1 further comprising a laser sight.

### Claim 5 (depends on 1)

The portable lachrymatory and electrical device of claim 1 further comprising a gearbox and gears operable to change a rotation rate between the motor and the pump.

### Claim 6 (depends on 1)

The portable lachrymatory and electrical device of claim 1 further comprising an intermediate motor controller circuit electrically connected to the battery and the motor.

### Claim 7 (depends on 1)

The portable lachrymatory and electrical device of claim 1 comprising a single pump.

### Claim 8 (depends on 1)

The portable lachrymatory and electrical device of claim 1, wherein the device excludes a lachrymatory composition cartridge having a relative high pressure with respect to ambient environment.
