Description

The invention relates to personal protective equipment, in particular to stun guns.

Known stun device (RF patent No. 2222761 C2, class F41B 15/04, publ. 01/27/2004) containing an autonomous power source, switch, DC / DC converter, power supply capacitor, output air gap, high voltage pulse transformer connected to working electrodes. Moreover, a capacitor of 120-300 pF is connected in parallel with the high-voltage winding of the high-voltage pulse transformer.

An electroshock device is also known (RF patent No. 2305246 C1, class F41B 15/04, published August 27, 2007), which contains a power source, a switch, a converter, a storage capacitor, a high voltage switch, a high voltage pulse transformer, and an additional storage capacitor charged from the converter through the diode and discharged to the target through the striking electrodes. An arrester is included in the discharge circuit of the additional capacitor. The high-voltage winding of the transformer has a diode that does not allow the discharge of an additional capacitor through the high-voltage winding of the transformer.

A common disadvantage of the devices described above is that they use a circuit solution containing many elements, which causes the loss of energy transmitted to the load in each of them. This reduces the efficiency devices.

Known stun gun (RF patent No. 2284440 C1, class F41B 15/04, published September 27, 2006), selected as a prototype, comprising a housing, inside of which a high pulse voltage source, equipped with a charger and an electric battery, is rigidly fixed via an activation button electrically connected to the working electrodes, and a pump that is connected via pipes to the reservoir for the electrically conductive liquid. The working electrodes are horizontal and hollow, connected by dielectric pipes to the pump outlet. The activating button and the pump drive are connected to the trigger by means of rods.

The disadvantages of this device is, firstly, that the battery lasts for a limited number of shots, after which it needs to be recharged or replaced, and secondly, that the working electrodes are rigidly fixed in the housing and are located in parallel, which can cause grazing, and , as a result of short circuits of electrically conductive liquid jets released from the stun gun into each other, and not reaching the target. In general, this reduces the efficiency and reliability of using a stun gun.

The objective of the invention is to increase the efficiency and reliability of the use of the stun gun due to its repeated use and changes in the location of the working electrodes, respectively.

The task is achieved by the fact that in the stun gun containing the housing, inside of which a source of high pulse voltage is rigidly fixed, electrically connected to hollow working electrodes, dielectric pipes, a pump and a reservoir for electrically conductive liquid are worn on their inner ends, unlike the prototype, dielectric pipes connected to the outlet of the reservoir for electrically conductive liquid, the input of which is connected to the pump, while the source of high pulse voltage is made in the form of high voltage piezoelectric generator with a loading device connected to the lever, and the working electrodes are located at an angle of 15 ° - 45 ° to the base of the housing, one of which is mounted on a dielectric roller connected by a rod with an angle regulator between working electrodes from 2 ° to 10 ° .

In this case, the device can be equipped with a lighting system consisting of an LED connected to an electric battery by means of electric wires.

The invention is illustrated in the drawing.

The drawing shows the design of the stun gun, a longitudinal section.

The stun gun includes a housing 1, in which a piezoelectric generator 2 with piezoelectric elements 3 mounted by a deformable loading device 4 is mounted, pivotally fixed at one end on the lever 5 and on the other hand in the housing 1 on the rollers 6. The terminals 7 of the piezoelectric generator 2 are connected using electrical wires (on not shown) with hollow working electrodes 8 and 9, on the inner ends of which dielectric pipes are worn 10. The working electrode 8 is rigidly fixed in the housing 1, and the working electrode 9 is on the dielectric roller 11, connected connected by a rod 12 with an angle regulator between the working electrodes 13. At the other ends, the dielectric tubes 10 are connected to the outlet of the reservoir for the electrically conductive liquid 14, the input of which is connected to the pump 15, driven by the rod 16, pivotally mounted on the lever 5.

From the side opposite to the loading device 4, the piezoelectric generator 2 has threaded plugs 17. A spring 18 is put on the protruding part of the loading device 4 between the housing 1 and the external lever 5.

An LED 19 is mounted on the housing 1, connected to the electric battery 20 by means of electric wires 21.

The stun gun works as follows. When the lever 5 is pressed, a loading device 4 is activated, which deforms the piezoelectric elements 3. As a result of the direct piezoelectric effect, a high potential electric potential is generated on the piezoelectric generator 2, which is discharged to the working electrodes 8 and 9 through the terminals 7 of the piezoelectric generator 2 and electric wires. At the same time, the pump 15 is driven by the rod 16, and the electrically conductive liquid from the reservoir for the electrically conductive liquid 14 enters through the working electrodes 8 and 9 in the form of jets outward from the housing 1. When the jets of the electrically conductive liquid get on the target body, high electric potentials close to the body, and discharges and defeat of the target occur.

The angular position of the working electrode 9, mounted on a dielectric roller 11, is controlled by the angle regulator between the working electrodes 13 by means of a rod 12 from 2 ° to 10 °.

Adjusting the angle between the working electrodes allows you to control the accuracy of the jets of electrically conductive liquid on the target.

The location of the working electrodes at an angle from 2 ° to 10 ° relative to each other virtually eliminates the possibility of intersecting jets of electrically conductive liquid, which increases the reliability of the use of stun guns.

Providing the device with a lighting system allows it to be used with equal efficiency both in daylight and in the dark.

Thanks to the use of a piezoelectric generator as a high-voltage voltage source, multiple use of the device is ensured. This increases the effectiveness of the stun gun.
