Summary of Invention

Problems to be Solved by the Invention

[0005] Spraying equipment used for training military units is required to be safe, easy to handle, stable, and to distribute the spray more uniformly.

[0006] Therefore, the present invention aims to provide a spraying device that can spray a spraying agent stably and uniformly. [Means for solving the problem]

[0007] The spraying device according to the present invention comprises a cylindrical main body, a spraying agent storage section formed inside the main body and containing the spraying agent, explosives provided below the spraying agent storage section, and an elastic body provided between the explosives and the spraying agent storage section, wherein the elastic body presses against the spraying agent storage section due to the combustion pressure generated when the explosives are ignited, thereby spraying the spraying agent to the outside.

[0008] The spraying device according to the present invention comprises a fuse for igniting explosives and a fuse holder for holding the fuse, characterized in that a through hole is formed in the fuse holder above the position of the lower end of the fuse.

[0009] The spraying device according to the present invention has a holder provided at the lower end of the main body, an angle adjustment part is formed at the lower end of the holder, and the main body is installed in an inclined state by placing the device on the mounting part with the angle adjustment part in contact with it.

[0010] The spraying device according to the present invention is characterized by comprising a housing that holds a spraying agent storage section, a cap that covers an opening formed in the upper part of the housing and has a spray hole formed through the top and bottom, and a spray hole plug provided in the spray hole.

[0011] The spraying device according to the present invention is characterized by having a support column member provided on the outside of the main body and movable in the vertical direction of the main body, and the main body being fixed to the mounting portion by inserting the tip of the support column member into the mounting portion.

[0012] The spraying device according to the present invention comprises an upper lid provided above the spraying agent storage section and a lower lid provided below the main body, characterized in that a measuring line is formed on the inside of the upper lid and an insertion section is formed on the outside of the lower lid that can be protected by inserting the tip of a support member into it. [Effects of the Invention]

[0013] The spraying device according to the present invention is equipped with an elastic body between the gunpowder and the spraying agent storage section. When the gunpowder is ignited, the combustion pressure generated causes the elastic body to press against the spraying agent storage section, releasing the spraying agent to the outside of the spraying device and allowing it to be sprayed. Because the spraying device uses the pressing force of the elastic body to spray the agent, it can spray uniformly without the main body exploding. Therefore, the spraying device according to the present invention is safer and more stable. [Brief explanation of the drawing]

[0014] [Figure 1] This is a cross-sectional view of a spraying device according to an embodiment of the present invention. [Figure 2] This is a perspective view showing the appearance of a spraying device according to an embodiment of the present invention. [Figure 3] This figure shows a holder that constitutes a spraying device according to an embodiment of the present invention, where (a) is a front view and (b) is a side view. [Figure 4] This figure shows a spraying device according to an embodiment of the present invention, fixed at an angle to the mounting section. [Figure 5] This figure shows the spraying device according to an embodiment of the present invention in a state where it is fixed perpendicularly to the mounting section. [Modes for carrying out the invention]

[0015] The spraying device according to this embodiment is used to spray a spraying agent, such as a simulated reagent, over a target area. The spraying device according to this embodiment will be described with reference to Figures 1 to 4.

[0016] As shown in FIGS. 1 and 2, the spraying device 1 includes a cylindrical main body (main body part) 2, a spraying agent housing 3 provided at the upper end of the main body 2, a spraying agent storage part 4 provided inside the spraying agent housing 3, a fuse holder 5 provided below the spraying agent storage part 4 and holding a fuse 5A inside, an ignition device 6 provided below the fuse holder 5, an upper lid 7 attached to the upper end of the spraying agent housing 4, and a lower lid 8 provided at the lower end part of the main body 2. The spraying device 1 is designed to have a size of 24 cm to 25 cm in length and 4 cm to 6 cm in diameter.

[0017] [Main body] The main body 2 is made of paper. For example, cardboard with a thickness of 2 mm to 5 mm and high strength can be used for the main body 2. On the outside of the main body 2, a support member 11 is provided, which is composed of a ring member 12 arranged on the outer circumference of the main body 2 and a rod-shaped member 13 whose tip is needle-shaped and is continuous with the ring member 12. By moving the ring member 12 along the outer circumferential surface of the main body 2 in the vertical direction Y, the support member 11 can move freely with respect to the vertical direction Y.

[0018] A holder 14 is attached to the lower end part of the main body 2. This holder 14 is used to tilt the spraying device 1 on the placement surface. As shown in FIG. 3(a), the holder 14 has a cylindrical upper member 15 and a hollow lower member 16 formed by connecting to the lower side of the upper member 15. Also, as shown in FIG. 3(b), the front part of the lower end of the lower member 16 is cut obliquely to form a curved part (angle changing part) 17. When the spraying device 1 is fixed to the placement surface, the entire curved part 17 is brought into contact with the placement surface. The fixing angle of the spraying device 1 is determined by the formation angle of the curved part 17. For example, this angle is set to 60 degrees.

[0019] [Spraying agent housing] The spraying agent housing 3 is made of resin and has an exposed part 20 that constitutes the upper side of the spraying agent housing 3, and a housing part 21 that is formed by connecting to the exposed part 20 and constitutes the lower side of the spraying agent housing 3. The exposed part 20 and the housing part 21 are integrally formed. Also, the outer shape of the exposed part 20 is formed larger than the outer shape of the housing part 21, and a stepped part 22 is formed. The spraying agent housing 3 is fixed to the main body 2 by inserting the housing part 21 into the inside of the main body 2 and abutting the stepped part 22 against the upper end of the opening of the main body 2. Therefore, the exposed part 20 is arranged outside the main body 2. A spiral groove is formed on the outer periphery of the exposed part 20, and a cap 23 is attached to the exposed part 20.

[0020] [Cap] The cap 23 has a circular injection hole 24 at the center of the upper surface, and a spiral groove is formed on the inside. By screwing the groove of the cap 23 into the groove of the exposed part 20, the cap 23 is attached so as to cover the opening of the exposed part 20. An injection hole plug 25 is attached to the injection hole 24, and the injection hole 24 is blocked by this injection hole plug 25. For the cap 23, for example, polypropylene is used, and for the injection hole plug 25, for example, polyethylene is used.

[0021] [Spraying agent housing part] The spraying agent storage part 4 is in a bag shape, and for this spraying agent storage part 4, for example, polyethylene or vinyl is used. The spraying agent storage part 4 is filled with a pseudo reagent (spraying agent) 4A. The pseudo reagent uses a liquid or powder form, for example, polyethylene glycol is used. Also, a piston (elastic body) 10 is provided between the spraying agent storage part 4 and the bottom of the housing part 21 of the spraying agent housing 3. The spraying agent storage part 4 is directly arranged on the piston 10.

[0022] [Fuse holder] The fuse holder 5 is installed inside the main body 2 facing vertically Y, and its upper tip is connected to the lower end of the spraying agent housing 3 (Figure 1). A recess is formed in the upper end of the fuse holder 5, and the explosive 9 is filled into this recess. A through hole 5B is formed on the lower side of the fuse holder 5, and this through hole 5B is formed above the position of the lower end of the fuse 5A. The fuse 5A is held in the fuse holder 5 with its upper end at a certain distance from the explosive 9. The length of the fuse 5A is 6 cm to 7 cm.

[0023] [Ignition device] The ignition device (ignition unit) 6 includes a primer holder 30, a primer 31 provided at the lower end of the primer holder 30, a firing pin cylinder 32 connected to the lower side of the primer holder 30, a firing pin spring 33 provided inside the firing pin cylinder 32, a firing pin 34 provided above the firing pin spring 33, and a firing pin 35 that releases the firing pin spring 33. The firing pin spring 33 is provided in a compressed state, and when the firing pin 35 is removed, the firing pin spring 33 is released, the firing pin 34 strikes the primer 31, and ignition occurs.

[0024] The top cover 7 is made of plastic and is attached to the top of the main body 2 and to cover the cap 23. The top cover 7 is removed from the spraying device 1 when in use. The bottom cover 8 is made of resin and is attached to the bottom of the main body 2 and to cover the holder 14. An insertion part 8A for inserting the tip of the rod-shaped member 13 is formed at the lower end of the outer circumference of the bottom cover 8. The bottom cover 8 is also removed from the spraying device 1 when in use.

[0025] The method of using the spraying device 1 according to this embodiment will be described below.

[0026] First, remove the top lid 7 and the cap 23 or spray nozzle plug 25, and fill the bag-shaped spraying agent container 4 with the simulated reagent 4A. The amount of simulated reagent to be filled should be determined appropriately, taking into account the amount and area to be sprayed. After filling with the simulated reagent 4A, reattach the cap 23 or spray nozzle plug 25. Next, remove the bottom lid 8, bring the curved portion 17 of the holder 14 into contact with the mounting surface, and place the spraying device 1 at an angle to the mounting surface. Then, as shown in Figure 4, slide the rod-shaped member 13 to the underside of the main body 2, insert its tip into the mounting surface, and fix and install the spraying device 1 on the mounting surface.

[0027] After setting up the spraying device 1, the spraying operation of the dummy reagent 4A is performed. Specifically, the firing pin 35 is pulled out and the firing pin 34 is forcefully struck against the primer 31 to ignite the lower end of the fuse 5A. This causes the fuse 5A to burn from the bottom upwards, igniting the gunpowder 9. Once the gunpowder 9 ignites, the combustion pressure of the gunpowder 9 pushes up the piston 10, compressing the spraying agent container 4. This compressive force causes the spray nozzle plug 25 to pop out of the cap 23, and the dummy reagent 4A is ejected from the spray nozzle 24 and sprayed over the desired area.

[0028] Next, the operation and effects of the spraying device 1 according to this embodiment will be described.

[0029] The spraying device 1 according to this embodiment includes a piston 10 provided between the gunpowder 9 and the spraying agent storage section 4. When the gunpowder 9 is ignited, the combustion pressure generated causes the piston 10 to press against the spraying agent storage section 4, releasing and spraying the dummy reagent 4A to the outside of the spraying device 1. In this embodiment, the spraying device 1 uses the pressing force of the piston 10 to spray the dummy reagent 4A, allowing for uniform spraying without the main body 2 or other parts exploding. Therefore, the spraying device 1 is safer and more stable. Furthermore, by providing the piston 10 between the spraying agent storage section 4 and the bottom of the spraying agent housing 3, the gunpowder 9 and the spraying agent storage section 4 are isolated by being positioned below the spraying agent housing 3, thus preventing the gunpowder 9 and the dummy reagent 4A from reacting.

[0030] In the spraying device 1 according to this embodiment, a through hole 5B is formed in the fuse holder 5 above the position of the lower end of the fuse 5A, and when the fuse 5A is ignited, smoke is discharged to the outside from the through hole 5B. Compared to cases where the through hole 5B is formed below the position of the lower end of the fuse 5A, or where no through hole 5B is formed, the fuse 5A is easier to ignite, thus improving the stability of the spraying operation of the spraying device 1.

[0031] The spraying device 1 according to this embodiment has a holder 14 at the lower end of the main body 2. The lower end of this holder 14 has a curved portion 17 that allows the angle of the spraying device 1 with respect to the mounting surface to be adjusted. Therefore, by placing the device with the curved portion 17 in contact with the mounting surface, the spraying device 1 (main body 2) can be tilted and installed in a stable state.

[0032] The spraying device 1 according to this embodiment has a cap 23 with a spray hole 24 formed therein, and a spray hole plug 25 is attached to this spray hole 24. After filling the spraying agent container 4 with the dummy reagent 4A, attaching the spray hole plug 25 prevents the dummy reagent 4A from leaking out to the outside even if the spraying device 1 is installed at an angle.

[0033] The spraying device 1 according to this embodiment has a support member 11 that is movable in the vertical direction Y of the main body 2, and the main body 2 can be firmly fixed to the mounting surface by inserting the tip of the support member 11 into the mounting surface.

[0034] The spraying device 1 according to this embodiment includes an upper cover 7 that is attached to the cap 23 and a lower cover 8 in which an insertion portion 8A is formed. By attaching the upper cover 7, the spraying agent housing 3 and the cap 23 can be protected, and by attaching the lower cover 8, the holder 14 can be protected. In addition, the needle-shaped tip of the rod-shaped member 13 is inserted into the insertion portion 8A, which protects the tip when not in use and ensures safety.

[0035] The spraying device 1 according to this embodiment has multiple applications, but for example, it can be used to display the situation of a chemically contaminated area and to conduct training for defense units, particularly for dealing with chemical attacks using chemical agent detectors.

[0036] Although this embodiment has been described above, it is possible to select or replace the configurations listed in the above embodiment, or to change them to other configurations as appropriate, as long as they do not deviate from the spirit of the present invention.

[0037] In this embodiment, the case in which the spraying device 1 is installed at an angle to the mounting surface has been described. However, as shown in Figure 5, for example, the spraying device 1 can also be installed and fixed vertically to the mounting surface. In this case, it is preferable to use a holder 14 that does not have a curved portion 17. [Explanation of symbols]
