Description

Eco-friendly, long-range tear-gas injection device {JET MACHINE FOR TEAR WATER}

The present invention relates to a portable tear liquid injection device,

More specifically, the use of environmentally friendly injection gases such as compressed air (or oxygen) provides fewer environmental problems and provides lightweight characteristics.

In addition to the filling pressure of the injection gas, the range of more than 15m is guaranteed by diminishing the inner diameter of the pipe connected to the injection gun.

Above all, the first, second and third connection nozzles of the tank, which constitute the tear liquid discharge part, the tear liquid and the injection gas injection part, and the injection gas filling pressure gauge measuring part, are separated separately, and the corresponding parts are screwed and detached. Easy to maintain,

It increases the service life of the gauge by preventing the unnecessary pressure load on the gauge after the initial pressure measurement when the injection gas is injected through the closing valve.

The present invention relates to an eco-friendly and long-range tear injection device in which a safety accident prevention function is introduced by introducing an exhaust port into the injection nozzle to enable a reduced pressure control exhaust when the internal injection gas is discharged for recycling after the tear gas is exhausted.

Utility Model Registration No. 0157188 (June 24, 1999) [Backpack-type gas injection device] can fill tear gas into the inside of the container, and in order to carry such a container in a backpack and spray the tear gas by portable.

A backpack portion having a suspender so as to be worn by a user and having a container supporting portion for fixing and supporting the container, and a gas container portion supported by the container supporting portion to fill a high-pressure liquid tear gas, and It comprises a handle for controlling to selectively inject the gas of the high pressure inside the gas container portion, and comprises a spray device for injecting the gas inside the gas container portion through the nozzle to the outside by the operation of the handle,

The gas container is provided with a container filled with a high pressure liquid tear gas, a three-way valve for controlling the injection of the tear gas inside the container through a nozzle, and an opening / closing handle for controlling the opening and closing state of the three-way valve. The vessel is provided with a pressure gauge for measuring the pressure of the residual gas therein.

However, the registration proposal can be found in the longitudinal cross-sectional view of FIG. 1 (FIG. 2 of the publication),

Rotating the opening and closing handle 25 for opening and closing the three-way valve 24 fastened to the upper end of the container 22 of the gas container 20 accommodated in the backpack portion to the inner pipe 27 and Through the nozzle 40 to be sprayed to the spray type device 30 of the gun type having a handle 32,

When the three-way valve 24 is opened by the opening / closing handle 25, the pressure gauge 26 installed on the other side of the three-way valve opens the flow path to measure the pressure of the tear gas remaining therein.

Unnecessarily the pressure of the injection gas is constantly applied to the pressure gauge, and the service life of the gauge is reduced accordingly due to the characteristics of the tear liquid injection device that is repeatedly used after exhausting the tear liquid.

Since the injection gas filling pressure is preferably maintained to ensure the injection pressure until the tear liquid is exhausted, measuring the pressure of the tear gas remaining therein is a practically unnecessary function.

In addition, the actual product applying the technology of the registration proposal is easily broken by considering the repeated use and harsh demonstration situation in the form of the nozzle and gauge are coupled to the outer cylinder of one body through the three-way valve 24 and fixed by welding. Since it is impossible to replace parts easily, there is a lack of product competitiveness due to the problem of not providing resource recycling function and increasing maintenance cost and new product purchase cost.

In addition, the injection device based on the registration proposal is a form in which the injection gas is injected together with the tear liquid and the [tear liquid + gas injection] is spread by the spray method, so that the injection distance is short, the concentration and aiming firing are difficult, and the demonstration suppression efficiency is lowered.

In addition, since the spray method is sprayed, the tear liquid is injected to the protest suppressor due to the reverse flow due to the reverse wind.

Furthermore, the registration proposal may be opened and closed by the opening and closing screw 21 in which the injection port 22a is screwed with the container 22. The injection port of this structure is significantly inferior in workability due to the gas leakage problem during gas filling. .

In addition, the injected injection gas is freon gas or carbon dioxide, which inevitably provides a poor working environment due to lack of oxygen in a filling workshop where gas leakage occurs, and also provides a cause of environmental pollution problems such as ozone layer destruction.

This disadvantage is that the products based on the present invention uses compressed air (or oxygen) as the injection gas, which is inevitably more prominent. Furthermore, since carbon dioxide is heavier than the compressed air, even if a small difference is obtained, the tear liquid injection device is usually used for a long time. This causes an increase in fatigue of the riot fighters who stand or walk and run.

The inventors have developed and filed various demonstration suppression equipment, including Patent No. 0899884 (May 21, 2009) [Portable tear liquid injection device for arresting], maintaining public power and maintaining public order through improvement of domestic and foreign demonstration suppression equipment. I'm contributing to

As a complaint of a great inconvenience in the field of the product based on the old Utility Model Registration No. 0157188

The present invention has been proposed to improve this.

Furthermore, an object of the present invention is to provide a tear liquid injection device that can increase the service life of the gauge by preventing the situation that unnecessary pressure load is applied to the gauge after the initial pressure measurement when the injection gas is injected through the closing valve.

In addition, an object of the present invention is to provide a tear liquid injection device that can ensure a range of 15m or more through the internal diameter of the pipe connected to the injection gun in addition to the injection gas filling pressure.

Since the injection gas remains in the tank and only the tearing liquid is injected, the injection distance is ensured until the tearing liquid is exhausted, and it is possible to provide a tearing liquid injection apparatus that can concentrate the injection and increase the efficiency of protest suppression through aiming and firing.

In addition, an object of the present invention is to provide a tear liquid injection device that introduces a safety accident prevention function by introducing an exhaust port into the injection nozzle to enable a reduced pressure control exhaust when discharging the internal injection gas for recycling after the tear liquid is exhausted.

In the present specification, the first to the second, the third to the third, and the like are referred to to distinguish the different components, and are not limited to the manufactured order, and the detailed description and claims of the present invention. The names may not match in the scope.

First, as shown in FIGS. 2 to 6, the tear liquid injection device J having an environment-friendly and long range according to the present invention is largely a tank 10, an injection gun 20, an injection nozzle 30, and a pressure gauge ( 40).

The tank 10 is preferably cylindrical to ensure ease of manufacture and pressure resistance,

First, second, and third connection nozzles 11A, 11B, and 11C, which constitute the tear liquid discharge part, the tear liquid and injection gas filling injection part, and the injection gas filling pressure gauge measuring part, respectively protrude from the upper part of the tank 10. Formed.

As shown in FIG. 3, the injection gun 20, the injection nozzle 30, and the pressure gauge 40 mounted on the first, second, and third connection nozzles 11A, 11B, and 11C, respectively. In order to protect the protection cover 13 is screwed to the fastening bracket 15 welded to the two sides of the tank 10, it is guaranteed to prevent breakage of each part in the harsh demonstration site.

In particular, the protective cover 13 has a structure that is bent in a polygon for bending strength improvement, productivity improvement, and surface contact with the flat bracket type fastening bracket 15.

The spray gun 20 is connected to the flexible hose 21,

The flexible hose 21 is connected to the first connection nozzle (11A) and is connected to the connector 23 having an opening and closing edge (23A) for safety,

As can be seen in FIGS. 3 and 5, the connector 23 extends to the bottom of the tank 10 for complete exhaustion of the filled tear liquid L (see FIG. 5) and the first connection nozzle ( 11A) is communicated with the outflow pipe 25 coupled to the inner bottom.

In particular, the connector 23 is screwed to the first connection nozzle (11A) separately from the injection nozzle and the pressure gauge in a screw coupling method, it is easy to replace for assembly and maintenance,

Furthermore, the end L-shaped tube 21a (see FIG. 2) of the flexible hose 21 is coupled to the connector 25 in a structure capable of arbitrary rotation by 360 degrees to prevent twisting of the hose, thereby improving convenience of use. Help

In addition to ensuring the range of the tear gas L by the filling pressure of the eco-friendly injection gas G, in particular, the injection gas which is compressed air (or oxygen) (see FIG. 5),

Compressed air (or oxygen), which is lighter than Freon gas or carbon dioxide, is located above the tear gas and pressurizes the tear fluid downward, so that the injection gas remains inside the tank.

Only the tear liquid is injected through the outflow pipe 25 arranged to extend to the bottom of the tank 10 and the concentrated spray is possible. Can be used to suppress the targets of the extreme radical protesters, thereby reducing controversy and increasing the efficiency of protest.

There is no problem of backflow of tear liquid from the back wind, which can help improve the safety of protesters.

In order to ensure the tear liquid (L) range until the last (about 15 m or more), in the present invention, the cross-sectional area of each component flow path (that is, the outflow pipe 25> flexible hose 21> spraying 20) is used. Internal diameter).

On the other hand, the injection nozzle 30 is also screwed to the second connection nozzle (11B) of the upper tank 10 to ensure the assembly and replacement convenience.

In addition, as can be seen in the upper enlarged circle of Figure 3, the injection nozzle 30 is provided with an exhaust port (30g) at the lower end (the upper end of the screw portion)

When the tear gas (L) is exhausted and the internal residual injection gas (G) is discharged for recycling, the reduced pressure control exhaust is possible.

This is because when the injection nozzle 30 is completely removed, the residual injection gas (in the present invention, only the tear liquid is injected and the injection gas remains, so the initial injection pressure is maintained almost intact, so the need for control when discharging the residual gas is greater) In spite of the fact that the worker may be injured by eruption,

In the present invention, the injection device (J) is controlled by the gas is gradually released through the exhaust port (30g) in the initial release of the injection nozzle 30, it is possible to prevent a safety accident.

Meanwhile, an O-ring 30p is coupled to the upper portion of the exhaust port 30g to ensure the sealability.

Such a packing member is provided for each coupling portion of each component to ensure airtightness or watertightness.

In addition, as shown in Figure 5, for the easy coupling of the injection hose (H) at the time of filling the tearing liquid (L) and injection of the injection gas (G)

It is preferable that the quick connector 33 is provided on the injection nozzle 30.

This quick connector 33 includes a crown bite 33A composed of rings 33a in which downwardly bent elastic teeth 33b are spaced apart on the inner circumferential surface as can be seen in the upper enlarged circle of FIG. 5. .

The injection hose H (injected to the inner bottom of the injection nozzle 30) (preferably, a packing member is provided at the bottom contact surface of the injection hose inside the injection nozzle) is provided on the elastic teeth 33b of the crown bite 33A. It is convenient because it is prevented from being caught at random.

After the tear gas (L) and injection gas (G) injection is completed, press the exposed release button 33B of the quick connector 33, the lower end of the button 33B presses the elastic teeth 33b, so the injection hose (H) Can be separated.

The release button 33B is coupled to the inside of the quick connector 33 flow path and is displaced to allow the elastic teeth 33b of the crown bite 33A to be pressed without any separation.

The release button 33B stays in the initial position by the elasticity of the elastic teeth 33b without applying external force.

On the other hand, the injection nozzle 30 is provided with a check valve 31 (illustrated as a hidden line in a circle enlarged in FIG. 3 for convenience), so that they are randomly ejected when the tear liquid L and the injection gas G are injected. No leakage of the injection gas is prevented even after the filling is completed.

On the other hand, after the injection of a certain amount of tear liquid (L) into the tank 10 through the injection nozzle 30, the filling pressure of the injection gas (G) is confirmed by the scale change of the gauge.

In particular, the injection gas (G) is an environmentally friendly injection gas (G), such as compressed air, and thus has low environmental problems and provides light weight characteristics, and in particular, due to the lack of oxygen in a filling workshop where gas leakage occurs when using freon gas or carbon dioxide. There is no problem of providing poor working environment, and there is no fear of environmental pollution such as ozone layer destruction.

In addition, since the conventional injection gas Freon gas or carbon dioxide is used to fill the tank at a high pressure, there is a risk in injecting gas into the tank 10 of the injection device,

In the present invention, the compressed air is used as the injection gas, and since the compressed air is supplied through a conventional compressor, it is low in pressure, so safety problems do not occur.

In addition, when using compressed air other than Freon gas or carbon dioxide as the injection gas, even though there is a small difference, there is a problem of increasing fatigue of suppression personnel who stand against the tear liquid injection device for a long time or suppress the walking while running. It will be less.

The pressure gauge 40 is screwed to the third connection nozzle (11C) of the tank 10 to ensure the removable and maintenance convenience. The pressure of the injection gas G to be filled should be a pressure that can guarantee the injection distance until the tear liquid is exhausted even when the tear liquid is reduced because only the tear liquid is injected according to the use in the demonstration and suppression process.

In addition, the pressure gauge 40 is provided with an on-off valve 41 to open the valve 41 so that the first pressure measurement when the injection gas (G) is injected, and then close the valve 41 after the gas filling is completed By preventing an unnecessary pressure load on the gauge 40, the service life of the pressure gauge 40 used during initial injection and refilling of the injection gas G may be increased.

On the other hand, as shown in Figure 6, the tear liquid injection device (J) according to the present invention is convenient because the tank 10 is put into a portable means, especially the backpack (B) can be moved and used by the protest riot fighters on the back. .

In the above description, although the conventionally known techniques related to the tear liquid specification, the principle of the spray gun, and the like are omitted, those skilled in the art can easily infer, infer, and reproduce them.

In addition, in the above description of the present invention with reference to the accompanying drawings described with a tear liquid injection device having a specific shape and structure, the present invention is various modifications, changes and substitutions by those skilled in the art, such modifications, changes and substitutions Should be construed as falling within the protection scope of the present invention.
