Description

Device for spraying tear gas

More particularly, the present invention relates to a syringe-type syringe injector for injecting a syringe solution by pumping a user without using a separate high-pressure gas container or tear gas containing a gas therein.

The tear liquid spraying device is mainly used for the self-defense, and it can be said that it is a device which interrupts the sight of the other party and injects the shock by spraying the leakage solution to the other party. Such sneeze sprayers generally use a high pressure built in a launcher, or a bullet filled with a sneaker is filled with high pressure.

However, the tear liquid spraying apparatus using the high pressure in this way uses the explosive force of the explosive powder at the same time as using the substantially high pressure. It is natural that it is necessary to follow a certain degree of risk in use as well as manufacturing.

The main object of the present invention is to provide a syrup injector in which general pumping is used irrespective of a gunpowder and a high pressure, whereby safety in manufacturing and use is sufficiently secured.

It is to be understood that the object of the present invention is to provide a method for manufacturing a fuel cell, which is capable of securing safety because it does not utilize a powder and high pressure in a manufacturing process. Further, It can be said that it means that the safety of the user can be secured as much as possible.

According to the present invention, there is provided a syringe injector comprising: a casing rotatably supported by a trigger; A sneak valve installed inside the casing and having an outside air inlet hole which is closed by a ball valve by a spring and is opened by a pressure difference with the outside air; A stationary pipe fixed to the inside of the casing and having a first ball valve installed at the front to allow only the leaking solution to flow forward; Wherein a second ball valve is provided in the fixing pipe so as to be able to move forward and backward at a predetermined distance in conjunction with the operation of the trigger and to allow the leakage solution to flow forward only in the rear, A movable tube which can be introduced via a valve; When the trigger is pulled, the tear fluid in the space between the tear fluid supply pipe and the fixing pipe is injected forward through the injection hole corresponding to the movement distance of the tear fluid supply pipe.

It is preferable that the casing of the present invention has a pistol shape.

According to the embodiment of the moving tube of the present invention, it comprises a working tube connected to a flexible connecting pipe connected to the inside of the sneak leak container, and a trough fluid feeding pipe connected to and interlocked with the working tube. Here, the second ball valve is provided on the rear side of the tear liquid supply pipe.

According to the present invention having the above-described configuration, it is understood that a gun-type syringe injector that does not use gunpowder or high pressure at all is provided. Therefore, it can be realized not only in terms of manufacturing, but also in a simple configuration, and also in that it is safe in use, and has a merit that sufficient pressure can be applied to the other party.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional exemplary view of a tear liquid dispenser of the present invention. Fig.
2 is a cross-sectional exemplary view of the launch state of a feces liquid launcher of the present invention.

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. Fig. 1 shows a state before firing of the sneeze sprayer of the present invention, and Fig. 2 shows a state during firing. As shown in FIGS. 1 and 2, the spraying apparatus of the present invention includes a casing 10, which is rotatably supported by the radiation wheel 12 while having an overall outer shape. In the illustrated embodiment, it can be seen that the casing 10 is formed to have the shape of a handgun.

A leakage liquid container 20 is provided in the casing 10 and is designed so that the leakage liquid can be introduced into the leakage liquid container 20 by using a stopper 24 that can be opened and closed if there is no leakage liquid. The connection pipe 21 provided inside the leakage solution container 20 is connected to the operation pipe 22 so that the leakage solution in the interior can be supplied to the inside of the operation pipe 22.

And a tear liquid supply pipe 32 is coupled to the front portion of the operation tube 22 so that the operation tube 22 and the tear liquid supply tube 32 interlock with each other. A fixing pipe 42 is installed inside the casing 10 on the outer surface of the tear liquid pipe 32. The fixing pipe 42 is fixed to the fixing groove 44 by fixing projections 62 The fixing tube 42 is held in the casing 10 in a fixed state.

A spring 46 is interposed between the protruding portion 42a formed on the outer side of the fixing pipe 42 and the protruding portion 32a formed on the outer side of the tear liquid supply pipe 32. Accordingly, when the radioactive cigarette 12 is pulled, the trigger 12 pivotally moves the pin Pa, and the trigger upper end 12a pushes the sidestream fluid supply tube 32 forward. The tear liquid supply pipe (32) is fixed within the fixing pipe (42) for a predetermined interval.

A ball valve 36 is provided in the rear of the tear liquid supply pipe 32. The ball valve 36 is elastically supported backward by a spring 34. [ The ball valve 36 allows the flow of the sneaking liquid into the trough liquid supply pipe 32 through the connecting pipe 21 and allows the flow in the opposite direction Do not.

Further, another ball valve 52 is closely attached to the front of the fixing pipe 42, and the rear side is elastically supported by the spring 54. [ Therefore, it can be seen that the ball valve 52 allows the sneaking solution to be sprayed forward and blocks the flow in the opposite direction. The spring 54 pushes the ball valve 52 rearward while the spray hole 64 is supported by the molded orifice end 60.

Hereinafter, the overall operation of the pistol-type tear gas spraying apparatus having the above configuration will be described. The state shown in Fig. 1 shows a state before the trigger 12 is pulled. In this state, a tear liquid is contained in the tear liquid supply pipe (32) with the fixing pipe (42). In this state, the user must pull the trigger 12 to inject the leakage solution.

When the trigger 12 is pulled, the trigger upper end portion 12 pushes the tear line supply tube 32 forward. For example, the upper end portion 12, which is branched in the form of a pawl, projects the projecting portion 32a of the tear liquid supply tube 32 forward . The working pipe 22 is connected to the tear liquid pipe 32 so that the working pipe 22 is connected to the connecting pipe 21. The connecting pipe 21 is formed of a flexible pipe so that the motion of the working pipe 22 can be absorbed.

When the tear liquid supply pipe 32 moves forward in the fixing pipe 42, the space between the tear gas supply pipe 32 and the fixing pipe 42 is substantially reduced, Moves a certain distance forward against the force of the spring (54). The ball valve 52 moves forward to move the tear liquid into a gap that is spaced apart from the end of the fixing pipe 42 (FIG. 2).

Then, the tear liquid which has moved as described above flows through the inner surface of the orifice member 60 at the front end portion and is ejected into the injection hole 64. The inner surfaces of the ball valve 52 and the orifice member 60 are not entirely clogged but have a structure capable of moving the trough as described above. Here, the reference numeral 65 is a ring-shaped member fixed to the inner surface of the orifice member 60 so as to support the ball valve 52.

In this way, in the process of pulling the trigger 12 backward, the tear liquid in the space between the tear liquid supply tube 32 and the fixed tube 42 is discharged by the amount corresponding to the stroke distance at which the tear liquid supply tube 32 goes forward (64). Then, after the tear liquid is sprayed, the user places the trigger 12.

When the trigger 12 is in the free state, the tear liquid supply pipe 32 moves backward due to the elastic restoring force of the spring 46. At this time, the operation tube 22 also moves backward through the tear liquid supply pipe 32. Here, when the leaking solution is sprayed, the pressure inside the liquid supply pipe 32 is low and the inside of the operation pipe 22 is in a state of high pressure by the filled solution. Therefore, in the process of moving backward, the ball valve 36 is separated from the operation tube 22 by the pressure difference.

When the ball valve 36 is spaced apart from the tip of the working tube 22, the tear liquid in the working tube 22 moves into the tear tube 32 through the gap. It can be seen that, due to the movement of the tear liquid, the tear liquid inside the operation tube 22 is moved into the tear liquid supply tube 32 in the state where the radiation tube is set. In this state, as described above, the sneaking liquid is filled in the inner space between the tear liquid supply pipe 32 and the fixing pipe 42, and the pair of ball valves 36, So that it is prevented from coming out. This is as shown in Fig.

In the illustrated embodiment, the operation tube 22 and the tear line supply tube 32 are separately formed, and the ball valve 36 is provided at the tip of the operation tube 22 or at the rear end of the tear liquid supply tube 32 . However, it is also possible to form the operation pipe 22 and the tear liquid supply pipe 32 integrally. It is sufficient that the operation tube 22 and the trough liquid supply tube 32 are formed into one tube (tear liquid supply tube) and a ball valve 36 is provided in the tear liquid supply tube 32.

Thus, in the state shown in Fig. 1, when the user pulls the trigger again, the leaking solution will be injected through the injection hole as described above. As described above, when the trigger is released, the tear liquid is filled in the tear liquid supply pipe and the fixing pipe as described above.

When the leakage liquid is sprayed in this manner, the pressure of the leakage liquid in the leakage liquid container 20 will be substantially consumed and the pressure will be lowered. 2, the ball valve 29, which blocks the outside air supply hole 27 by using the elastic force of the spring 28, is released from the pressure difference by the pressure difference, , The outside air supply hole 27 is opened. Then, the inside of the trough vessel 20 can have the same pressure as the atmospheric pressure, and then the trough 20 is supplied.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
