Description

Portable tear bomb

The present invention relates to a portable tear gas, and more particularly to a tear gas that can eject the internal filling quickly without ignition or explosion.

Injectors for storing the filling therein and ejecting the filling to the outside by a constant mechanism are widely used. For example, a tear gas for suppressing a demonstration, a fire extinguisher for extinguishing a fire, and a pest insecticide are mentioned. Such injectors must be able to safely store the internal filling, the filling must be ejected safely to the outside, and rapid and accurate ejection is required.

However, conventional representative injectors have some problems in stability and ejection action.

For example, tear gas, one of the suppression equipment used in the demonstration site, is a suppression weapon developed by applying military grenades, and ejects the innermost gas through the blower's blow and explosive process. In the process, the outer containers that make up tear gas were also scattered in pieces, causing physical damage to protesters and innocent citizens.

In addition, the grenade-type tear gas is composed of various components such as a trigger means, a detonator and an explosive material, and a safety means as a component, which has a high production cost and a complicated manufacturing process.

In addition, the grenade-type tear gas emits only the powder at a certain point dropped by the user's throwing, and cannot spread the powder to the adjacent area, so that the demonstration suppression effect is very low. On the other hand, the existing tear gas accompanying the explosion process is also difficult to throw near the protest area due to the risk of physical injury.

On the other hand, fire extinguishers, which are generally used for extinguishing fires, are very inconvenient to carry and should be used close to the place where the fire occurred for extinguishing fires. There is a very difficult problem. In particular, there were many difficulties in the early fire extinguishing with existing fire suppression equipment in places such as high voltage electric facilities, dangerous goods storage areas, and underground facilities, which are dangerous for human access.

Therefore, an object of the present invention is to ensure the stability of the tear gas storage and use by replacing the explosion mechanism for ejecting the filling with other means.

Another object of the present invention is to improve the ejection action of tear gas quickly and effectively.

In order to achieve the above object, the present invention is filled with the liquid filling and compressed gas in the inner empty space, the casing is formed with an upper opening for filling and the lower opening for gas injection; A spouting body coupled to an upper opening of the casing, having a through hole formed at a center thereof, and a nozzle portion formed at a lower end of the through hole; A spouting stopper inserted into the through hole to block the nozzle part from the outside; A first elastic member elastically supporting the jet plug in the nozzle portion; An injection port body coupled to the lower opening of the casing, a through hole formed at a center thereof, and a gas injection hole formed at a lower end of the through hole; An injection hole stopper inserted into the through hole to block the gas injection hole from the outside; And a second elastic member elastically supporting the inlet stopper in a downward direction of the casing; and a handle fixed to the spout body by a safety pin.

Sealing members may be inserted into the through-holes of the outlet body and the through-holes of the inlet body to prevent the filling from counting out.

The filling material charged into the casing may include various kinds of materials according to the purpose of use, and in particular, it is preferable that the protest tearing material or the fire extinguishing material is used.

Hereinafter, the technical configuration of the present invention with reference to the drawings in more detail. 1 and 2, it can be seen that the casing 100 constituting the body of the tear gas and the spout body 120 are integrally coupled to the casing 100. The outlet 110 is coupled to the handle 110 is fixed by the safety pin 112, one end of the safety pin 112 is fitted with a safety ring 114.

The liquid filling 102 is charged into the casing 100. The filling material may be a chemical coal such as CS bomb, fire extinguishing material for fire extinguishing, or various materials for various uses may be charged according to other purposes of use.

In addition, the gas 104 in a compressed state is injected into the casing 100 together with the filler 102. Compressed gas 104 serves to provide propulsion to the ejection of fill 102. Nitrogen is preferred as the gas 104, and other gases may be used as long as they do not chemically react with the fill 104.

The casing 100 has a cylindrical shape in the drawing, but is not necessarily limited to a cylindrical shape and may be elliptical or spherical. However, it is preferable that the shape has a curved surface so that the pressure on the casing surface is uniformly distributed by the compressed gas inside the casing.

Since the casing 100 is filled with a liquid filler 102 and must withstand high pressure by the compressed gas 104, the casing 100 should be made of a material having low chemical stability and stability and excellent strength and toughness. Therefore, metal materials, such as aluminum and stainless steel, high strength plastics, etc. are suitable as a material of a casing.

One end of the casing 100 is provided with an opening 106, which is a passage through which the filling 102 is ejected to the outside by the driving force of the compressed gas 104, and the ejection port is blocked to control the ejection action by blocking the opening 106. Body 120 is coupled.

The ejection opening body 120 has a through hole 121a formed therein and a nozzle portion 121b formed by reducing the size of a passage ejected at one end of the through hole. The nozzle stopper 122 is inserted into the nozzle part 121b to prevent the ejection of the filling, and the first elastic member 124 elastically supporting the jet stopper 122 in the direction of the nozzle part 121b has a through hole. It is inserted into the (121a), it can be seen that the outlet cover 128 covers the through hole 121a of the outlet body 120 while pressing the first elastic member 124.

Looking at the structure of the outlet body 120 in more detail, a through hole 121a penetrating the inside of the cylindrical body is formed, the lower end of the through hole is formed with a nozzle portion 121b to have a smaller diameter than the through hole. . The outlet body 120 is fixed to the inner peripheral surface of the opening 106 of the casing 100 by screwing. The spouting stopper 122 blocks the nozzle part 121b in the through hole 121a, and the nozzle part is provided in the spouting stopper 122 while the first elastic member 124 is fitted to the outer circumference of the spouting stopper 122. An elastic force is applied in the direction 121b. The first sealing member 126 is inserted between the jet plug 122 and the nozzle portion 121b so that the filling 102 inserted into the casing 100 does not leak due to the propulsion force by the compressed gas 104. It is.

In addition, the handle 110 which suppresses the elastic force by the first elastic member 126 is fixed to the ejection outlet body 120 by the safety pin 112 while pressing the ejection outlet cover 128. The end 110 ′ of the handle 110 is curved and fitted into an annular hole 121c at one end of the outlet body 120.

The lower portion of the casing 100 is formed with a gas injection unit for injecting gas. The position where the gas injection portion is formed is preferably the lower portion of the casing, but it is not necessarily limited thereto. The detailed structure of the gas injection unit is as follows.

The lower surface of the casing is provided with an opening 140 which is curved inward and has an inner injection hole 142 formed at the center thereof. The injection hole body 150 is coupled to the opening 140 by screwing. The injection hole body 150 has a through hole 151a formed therein, and a gas injection hole 151b is formed below the through hole 151a to have a diameter smaller than that of the through hole 151a.

In addition, the gas is injected into the casing 100 only, and as a mechanism for preventing the filling or the injected gas from flowing out of the casing 100, the gas inlet stopper 152 to block the gas inlet 151b, and A second elastic member 154 for elastically supporting the gas inlet stopper 152 in the direction of the gas inlet 151b is further provided.

The second elastic member 154 has one end in contact with the inner injection hole 142 of the opening 140 and the other end is in contact with the gas inlet stopper 152 causing an elastic force so that the gas inlet stopper 152 is casing. (100) serves to force the force only downwards.

The second sealing member 156 is inserted into a portion where the injection hole body 150 and the gas injection plug 152 meet to prevent the gas 104 or the filler 102 from leaking out of the casing 100.

The operation of the present invention having such a technical configuration will be described in detail with reference to FIGS. 3 and 4.

The tear gas according to the present invention charges the filler into the casing 100 and injects gas into the gas injection unit while the ejection control unit is coupled to increase the pressure inside the casing. The gas may be injected into the casing 100 into the gas injection hole 151b of the injection hole body 150 using a separate gas injection mechanism (not shown). When the gas is injected at high pressure, the gas injection hole stopper 152 elastically supported by the second elastic member 154 and blocking the internal injection hole 142 from the outside is pushed out by the high pressure, as shown in FIG. 3. As can be seen, there is an open microspace. High pressure gas is injected into the microcavity so that the gas is filled in the casing 100. In FIG. 3, the arrow schematically shows the flow of gas injected into the casing 100 through the injection hole body 150.

In the present invention, since the gas 104 injected into the casing 100 provides a driving force for the filling 102 to be ejected to the outside, a large amount is injected to maintain the inside of the casing 100 at a high pressure. desirable.

Once the gas is injected at high pressure, the gas inlet stopper 152 is large due to the elastic force of the second elastic member 154 of the injection hole body 150 and the pressure of the gas 104 injected into the casing 100. The force is received, and the inner injection hole 142 is blocked from the outside.

The tear gas according to the present invention can be stored and carried in a state in which the filling material and the compressed gas are contained, and in some cases, the compressed gas may be injected into the casing while only the filling material is charged.

In case of emergency, tear gas according to the present invention can be used by the following steps. First, the user pulls the safety ring 114 while holding the casing 100 and the handle 110 to remove the safety pin 112 from the spout body 120. In the state of holding the handle 110, since the spout cover 128 is pressed by the handle, the filling 102 in the casing 100 is not ejected to the outside. When the user throws the casing 100 to a target point while holding the casing 100 and the handle 110, the pressure inside the casing 100 and the elastic force of the first elastic member 124 simultaneously act, The spout stopper 122 is strongly pushed out of the spout body 120. Accordingly, the spout cover 128 and the handle 110 is momentarily separated out of the spout body 120.

When all of the elements blocking the through-hole 121a and the nozzle part 121b are removed from the jet body 120, the filling 102 charged inside the casing 100 is combined with the compressed gas 104 and the nozzle part ( 121b) is ejected at a high speed.

This series of processes occurs very quickly due to the high pressure compressed gas 104, and therefore the ejection action occurs quickly. 4 schematically shows how the filler 102 is ejected. As the filling 102 is ejected out of the casing 100, the ejection itself generates one propulsion force so that the casing 100 has a rapid movement. As if the balloon is moving in an irregular movement as the internal air escapes, the casing 100 is rapidly moving around to eject the filling.

In addition, the tear gas according to the present invention may hold the casing 100 in a state where the user removes only the handle 110 and may eject the filling in the target direction.

The tear gas of the present invention may be used for various purposes depending on the type of the filler 102.

For example, if the packing material is CS liquid for demonstration suppression, it can be used as a tear gas and thrown at the demonstration site to quickly discharge the gas. In particular, there is no fear of physical damage to the protesters because they do not use primers or initiators. In addition, there is no need for a separate trigger, bringing the effect of suppressing the demonstration safely at close range.

On the other hand, in the case of using the liquid extinguishing fire extinguisher as a filling material, as a portable fire extinguisher rather than a tear gas, it is possible to obtain an effect of suppressing a fire by throwing a fire extinguisher as if it is throwing a grenade at the fire site. In particular, the high speed ejection of the package causes irregular movement of the casing to eject the package from place to place at the site of the fire. Therefore, it can be effectively used for fires generated in electrical facilities, dangerous areas, etc., which are difficult for people to approach. It will also have a very good effect on initial fire fighting in your home or building.

In addition, the tear gas of the present invention may be used in various applications depending on the type of filler used.

As described above, the tear gas according to the present invention is easy to carry and store, and does not require a primer or explosive, which may cause physical damage to the human body, thereby greatly improving safety in use. In addition, the structure and form are simple, and no expensive parts are required, so the manufacturing cost and productivity are expected to be excellent.
