Description

The invention relates to means of self-defense with the use of aerosol cans for spraying active damaging substances with a tear effect and serves to temporarily disable manpower with a jet of liquid with irritating properties for the purpose of active self-defense.

A firing device is known from the prior art, which includes a composite magazine body in the form of left and right cheeks, located at an angle with respect to its neck, in which a spring-loaded cartridge feeder is installed, a cartridge delay in the form of a rotary star, a base carrying a shock trigger, trigger. The device is equipped with a safety lock that can be fixed in two positions, the flag of which is located on the side surface of the magazine case and is rigidly connected to the trigger axis, on which there is a longitudinal keyway protrusion interacting with a groove in the form of a sector recess made on the trigger in one piece with a hole for axis. The lower arm of the trigger is made in the form of a button, in which the front end is a rectangle in plan, and the sidewalls having the shape of a sector of a circle, the center of which passes through the axis of the trigger, are mated with narrow vertical niches on the cheeks of the magazine body [RU 2357177 C2. Shooting device. IPC F41C 3/00, F41H 9/10, F41A 17/22. Application No. 2007118335/02 dated 16.05.2007, publ .: 27.05.2009 in Bul. No. 15]. The disadvantages of this invention are the absence of a laser designator and a built-in illumination source, low reliability and weight and dimensions due to the large number of device elements and a mechanical method of initiating work.

Also known is an aerosol device of the "CHARODEY F" and "CHARODEY L" models, consisting of a body with two cavities for installing pyromechanical cylinders in them, two sear buttons, a fuse and a stop. Each cavity contains a drummer with a mainspring and a retainer, each interacting with its own sear button. The device is supplied with locks extended from the case, a flashlight or a laser designator (equipment depends on the model) [http://tulataman.ru/catalog/bezlitsenzionaya-produktsiya/ustroystvo-aerozolnoe-s-piromekhanicheskimi-ballonami-modeli-charodey/]. The disadvantages of this device are low reliability due to the mechanical method of initiating work, low charge.

The closest to the claimed technical solution is a self-defense weapon PB-4-1ML "OSA", containing a body, a holder of cartridges with sockets, barrels made in the form of cartridge cases with an electric igniter, and an actuation mechanism containing a pulsed magnetoelectric and / or electrochemical source current, electrically connected to a switchgear containing a block of contact units, the contact units of the unit are made floating, a laser designator is built into the body of the weapon, and a through hole is made in the holder of cartridges with sockets located in its middle part between the sockets of the holder of cartridges. In addition, an LED is located in the bottom of the housing, showing the degree of discharge of the electrochemical current source, and a light guide is located in the through hole of the holder. [patent for invention RU 2213923 C1. Self-defense weapon. IPC F41C 3/00, F41A 19/58. Application No. 2002128577/02, 24.10.2002, published: 10.10.2003 in Bul. No. 28; https://www.niiph.com/produktsiya/grazhdanskaya-produktsiya/kompleks-samooborony-osa.html]. The disadvantages of this invention are large weight, the need to replace the power source, low charge, lack of built-in lighting source, insufficient reliability.

The technical results of the proposed invention are increased reliability and durability, improved efficiency, reduced weight and dimensions and improved control and protection system of the device.

The technical results are achieved by the fact that the aerosol device, in addition to the fact that it includes a housing with a built-in laser designator and two LEDs powered by a lithium-ion rechargeable battery, with an actuation mechanism located inside the housing, containing a magnetic pulse generator, including an anchor, a coil, permanent magnets, a control board, an indicator of the discharge level of a lithium-ion battery, a removable holder with slots for installing canisters equipped with electric ignitors, adjacent to the device through spring-loaded contacts connected to the magnetic pulse generator through a control board, a fuse, trigger, springs, buttons holding the clip, and a button to turn on the LEDs, equipped with:

- a pulsed voltage source that generates an increased voltage value at the contacts of the cartridge capsule to overcome the resistance of oxide and fatty films that arise during the operation of the device and cartridges;

- a safety device designed to protect the control board from damage, as well as centering the cartridge in the device;

- a protection board that performs the functions of protecting the lithium-ion storage battery from overdischarge, as well as limiting the charging voltage;

- USB connector for connecting a charger, which makes it easy to recharge the power source.

In addition, the clip is made in a six-round design, which increases the efficiency of the device.

The laser pointer of the device is powered by a rechargeable lithium-ion battery.

The fuse performs the function of preventing the operation of the cartridges (accidental throwing of liquid with an irritant) when the trigger is accidentally pressed, as well as the function of turning on the laser designator.

The control board initiates the selection and start of the cartridge.

The drawing shows the claimed aerosol device.

The device works as follows.

Pressing the buttons 2 on both sides of the device remove the clip 1 from the device. Holding the clip 1 in the left hand, set six cans with a 10 mm × 80 mm irritant with the primer on itself, and the nozzle inside the store. After installing the cans, the clip 1 is installed in the device until it clicks, which is played by the clips of the clip. When installed, the cans contact the control board 3 through spring-loaded contacts 5.

To throw a liquid, they take the device in their hand, which is accompanied by pressing the fuse 7 with the palm, as a result of which it automatically turns off. Then they aim and energetically press the trigger 16. When the fuse 7 is shifted, the laser designator 17 is turned on.

When the trigger 16 is pressed, its protrusion displaces the slider 9, which pushes the armature 10, thereby breaking the magnetic circuit. In the extreme position of the trigger 16, the slider 9 is released and the armature 10 under the action of the magnetic field of permanent magnets returns to its original position, thereby closing the magnetic circuit. The slider 9 under the action of the spring returns to its original position. The trigger 16, under the action of the spring 8 installed on the safety catch 6, returns to its original position.

A current is induced in the coil 15, which is filtered by the elements of the protection board 14, and the resulting current pulse with a voltage of 18 V is used to initiate the electrocapsule in the cartridge, and also through a step-down stabilizer converts the voltage of 18 V into a voltage of 5 V to power the microcontroller, which in turn serves to memorize the last number of the initiated cartridge and to search for the next operable cartridge in cartridge 1. If all conditions are met, the microcontroller will give a signal to initiate the electrocapsule. Liquid will be thrown from the can. The liquid with the irritant is pushed out of the cartridge and sprayed in the form of an air-droplet jet. Throwing liquid from the can is almost noiseless and without recoil.

To turn on the flashlight, consisting of two ultra-bright LEDs 18, you must press the button 4 all the way. Button 4 has two fixed positions (on / off). The flashlight is powered by a lithium-ion rechargeable battery 11 installed in the device. The protection board 14 has functions to protect the lithium-ion rechargeable battery from overdischarge, as well as to limit the charging voltage. The device has a MicroUSB 13 connector for connecting a charger. Indicator 12 serves to signal a low battery charge. The red color of the indicator 12 indicates that the battery is almost completely discharged. Indicator 12 lights up simultaneously with the flashlight by pressing button 4.

In support of the declared characteristics of the device, a table is given in which the parameters of the proposed technical solution and similar developments are compared.
