As shown in FIG. 1, the gas injection device according to the present invention includes a body part 10 containing a liquid gas G and a gas G inside the body part 10. It is comprised by the operation part 30 to operate.

Gas injection device according to the present invention, the body portion 10 and the operation unit 30 is combined to constitute one gas injection device. And the body case 11 and the fixed case 34 is screwed by the screw coupling portion (Sa) to form a case body.

The liquid gas 12 is inserted into the body part case 11 forming the exterior of the body part 10, and is filled with, for example, a tear gas. The gas G filled in the inside of the body part case 11 is injected forward by the operation of the operation unit 30 as described later. A nozzle hole 13 for ejecting gas is provided at the front end of the body part case 11 containing the gas G, and the nozzle hole 13 is blocked by a cover shown by reference numeral 12 on the drawing. State is maintained. The cover 12 covers the nozzle hole 13 using, for example, silver foil or the like. However, the cover 12 is not limited to the silver foil, and if configured to be able to prevent the gas inside the body portion case 11 in the pre-launch state of the gas, any configuration can be, of course, yes For example, it can also be comprised from synthetic resin materials, such as vinyl, and can also be comprised from paper.

When the cover 12 is removed from the nozzle hole 13, the gas G inside is sprayed forward through the nozzle hole 13 formed at the end of the case 11 of the body part 10. The nozzle hole 13 may also include a packing member 14 formed of rubber or the like for aesthetic reasons.

A piston 15 is installed at the rear of the body part case 11 filled with the gas G, and a vent hole 18a and a ball 18b are provided at the rear of the piston 15. The supporting blocks 16 and 18 which are provided are fixed to the inside of the body part case 11. The support blocks 16 and 18 are one block in which two members are completed by screwing together. In the support blocks 16 and 18, the charging unit 17 having the charging unit 17a is inserted at the left side. When the impact member 32, which will be described later, is impacted from the left side, the charge part 17 is instantaneously moved from the inside of the support blocks 16 and 18 to the right side. Instantaneous movement of the charge portion 17 causes the charge 17a to ignite and explode by the ball 18b.

Next, the configuration of the operation unit 30 will be described. As mentioned above, the operation part 30 is a part operated in order to blow out the gas G built in the body part 10. As shown in FIG.

As shown, the operation unit 30, the case 11 of the body portion 10 and the fixing case 34 screwed and fixed through the screw coupling portion (Sa), and the outer side of the fixing case 34 It is coupled to the state, and includes an operation case 31 capable of advancing forward and backward. The fixed case 34 and the operation case 31 are formed in the shape of a writing instrument, and are formed of, for example, a cylindrical body. And an operating lever 33 is molded on the outside of the operation case 31. Since the operation lever 33 is molded in a shape similar to a clip of a general writing implement and is formed of synthetic resin, it has elasticity as a whole, and the middle portion 33b of the operating lever 33 is pressed by the user as shown by a dotted line in FIG. 2. By elastic deformation. And the end part 33a shown in the right side of the operation lever 33 is a state which protruded inward toward the said fixing case 34 side. Therefore, the end 33a is elastically urged toward the fixing case 34 by the overall elasticity.

And the locking groove 34a is formed at one side of the outer circumference of the fixed case 34. The locking groove 34a is formed to be caught by the end 33a of the operating lever 33 and is formed along the entire outer circumference of the fixed case 34. In addition, when carrying the writing instrument-type gas injection device according to the present invention, the operation lever 33 can also serve as a fixed in the pocket, such as a shirt or suit, as in the case of a general writing instrument.

An impact member 32 is inserted into the fixed case 34, and the impact member 32 is elastically supported to the right in the drawing by an elastic member 35 such as a spring. That is, the elastic member 35 is a state in which a predetermined elastic force is applied to the impact member 32 toward the right side from the inside of the fixed case 34.

And the left end 32a of the impact member 32 is configured to interlock with the operation case 31 in a state in which the fixed case 34 protrudes. That is, since the washer 32b is assembled in the state where the left end portion 32a of the impact member 32 penetrates the operation case 31 outward, the left end portion 32a is not separated from the operation case 31. have. Accordingly, when the operation case 31 is moved to the right side, it is moved to the right side by the right cap 31a of the operation case 31. When the operation case 31 is moved to the left side (pull surface), the washer ( The impact member 32 also comes out along the left side by 32b).

Next, the operation of the gas injection device according to the present invention will be described with reference to FIGS. 1 and 2 together.

The state shown in FIG. 1 is a state before using the gas injection device, that is, a state in which it is stored or carried. In this state, the inside of the body casing 11 is filled with a liquid tear gas, etc., and the impact member 32 also maintains its original position.

2 shows a state in which the user operates to inject gas in the gas injection apparatus according to the present invention. As shown, the user pulls the operation case 31 to the left. When the operation case 31 is moved to the left side, the operation lever 33 is also moved to the left side, so that the end 33a of the operation lever 33 is caught by the locking groove 34a of the fixed case 31. do. Thus, the movement of the operation case 31 is stopped in the state where the end 33a of the operation lever 33 is caught in the locking groove 34a. At this time, the end 32a of the impact member 32 is also Since it moves together with the operation case 31, the impact member 32 also maintains a state of being pulled to the left like the operation case 31.

In this state, as shown by the dotted line in FIG. 2, when the user presses the middle portion 33b of the operating lever 33, the middle portion 33b enters concavely. End 33a of 33 is lifted upward. When the end 33a is lifted upward, the end 33a is separated from the locking groove 34a.

In this way, when the end 33a of the operation lever 33 is separated from the locking groove 34a, the force that substantially fixes the operation case 31 to the fixed case 34 is removed. . At this time, the impact member 32 is fired to the right by receiving the elastic force of the elastic member 35 interposed between the fixed case 34 and. Of course, if the impact member 32 is momentarily moved to the right side, it is natural that the operation case 31 is also moved together.

When the impact member 32 is momentarily moved to the right by the elastic member 35, the right end of the impact member 32 moves while applying the impact to the right part 17. Then, the charge 17a instantaneously collides with the ball 18b, causing it to ignite and explode.

The gas generated due to the explosion of the charge 17a moves out of the vent hole 18a and moves the piston 15 to the right. Then, the piston 15 is moved from the inside of the body portion case 11 to the right with the same force. When the piston 15 moves from the inside of the body part case 11 to the right, the gas G therein is injected through the cover 12. When the gas G is sprayed through the nozzle hole 13 substantially, it will be sprayed through the nozzle hole 13 as a spray, and the size (diameter) of the nozzle hole 13 is the length of the charge 17a. It may be desirable to adjust the spray to be sufficiently sprayed in consideration of the force of the explosion and the capacity of the gas to be injected. At this time, when the cover 12 is made of silver foil, the gas will be ejected while the silver foil cover 12 is torn, and this gas pressure can be sprayed forward while pushing the rubber packing 14.

The present invention configured as described above can be seen that implements a writing-type gas injection device excellent in storage and portability. And the present invention by the embodiment shown in Figures 1 and 2 is not limited, of course, many other variations are possible within the technical scope of the present invention, for example, the following technical modifications It will be possible.

In the above-described embodiment, the impact force due to the explosion of the charge 17a is configured to be transmitted to the gas container 12 through the piston 15. However, it is, of course, also possible to configure the explosive force of the charge 17a to be used for direct gas injection. That is, if the configuration of the piston 15 is omitted, the explosive force of the charge 17a will directly push the gas G and the gas G will be injected through the nozzle hole 13 together.

The cover 12 may be made of silver foil or aluminum foil. That is, the cover 12 is sufficient if the cover 12 is configured to be removed or torn by the pressure of the gas ejected by the impact energy due to the explosion of the charge 17a so that the gas can be injected forward. Therefore, it is also possible to form a silver foil aluminum foil or the like, as well as to be composed of a synthetic resin material that can be removed at a predetermined pressure.

In the illustrated embodiment, it can be seen that the case 11 of the body portion 10 and the fixing case 34 of the operation portion 30 are screwed together with each other through the screw coupling portion (Sa). Using a screw coupling in this way means that the separation and coupling is easy, so after the injection of the gas once it will be possible to replace only the body portion 10. This point means that the operation part 30 can be reused by simply replacing the body part 10, and the body part 10 is substantially used as a single assembly.

According to the present invention as described above, the following advantages are expected.

First, by providing a gas injection device having the same appearance as a small writing implement, it can be easily used for self-defense or a method. Therefore, the writing instrument-shaped gas injection device according to the present invention is expected to be advantageous in portability and usability.

In addition, the gas injection device according to the present invention does not require a complicated configuration, such as a power supply and a current path, because the gas injection operation simply depends on the mechanical configuration. Therefore, it is possible to reduce the production cost of the overall configuration is simple, as well as to expect the advantages of improved productivity in the production process.
