[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-059643 Summary of the Invention [Problem to be solved by the invention]

[0005] A spraying device for spraying propellant used in military training is required to be safe and easy to handle, as well as stable and capable of spraying the propellant more uniformly.

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

[0007] The spraying device of the present invention comprises a cylindrical main body, a spray agent storage section formed inside the main body and storing the spray agent, gunpowder provided below the spray agent storage section, and an elastic body provided between the gunpowder and the spray agent storage section, and is characterized in that the elastic body presses against the spray agent storage section due to the combustion pressure generated when the gunpowder is ignited, thereby spraying the spray agent to the outside.

[0008] The spraying device of the present invention comprises a fuse for igniting gunpowder and a fuse holder for holding the fuse, and is 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 of the present invention is characterized in that it has a holder provided at the lower end of the main body, an angle change portion is formed at the lower end of the holder, and the main body is installed in an inclined state by placing the angle change portion in contact with the mounting portion.

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

[0011] The spraying device of the present invention is characterized in that it has a support member that is provided on the outside of the main body and can move in the vertical direction of the main body, and the main body is fixed to the mounting portion by inserting the tip of the support member into the mounting portion.

[0012] The spraying device of the present invention comprises an upper lid located above the spray agent storage section and a lower lid located below the main body section, and is 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 the support member. [Effects of the Invention]

[0013] The spraying device of the present invention includes an elastic body disposed between the explosive and the propellant storage compartment. When the explosive is ignited, the combustion pressure presses the elastic body against the propellant storage compartment, releasing the propellant outside the spraying device and dispersing it. Because the spraying device uses the pressing force of the elastic body to spray the propellant, it can spray uniformly without causing the main body to explode. Therefore, the spraying device of the present invention is safer and more stable. [Brief explanation of the drawings]

[Figure 4] 1 is a diagram showing a state in which the spraying device according to an embodiment of the present invention is fixed at an angle relative to the mounting portion. FIG. [Figure 5] 1 is a diagram showing a state in which a sprinkling device according to an embodiment of the present invention is fixed vertically to a mounting portion. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] The spraying device according to this embodiment is used to spray a spraying agent such as a pseudo-reagent over a target area. The spraying device according to this embodiment will be described with reference to FIGS.

[0016] As shown in Figures 1 and 2, the spraying device 1 comprises a cylindrical main body (main body portion) 2, a spray agent housing 3 provided at the upper end of the main body 2, a spray agent storage section 4 provided inside the spray agent housing 3, a fuse holder 5 provided below the spray agent storage section 4 and holding a fuse 5A therein, an ignition device 6 provided below the fuse holder 5, an upper cover 7 attached to the upper end of the spray agent housing 4, and a lower cover 8 provided at the lower end of the main body 2. The spraying device 1 is designed to be 24 cm to 25 cm long and 4 cm to 6 cm in diameter.

[0017] [Main unit] The main body 2 is made of paper, and for example, a strong cardboard having a thickness of 2 mm to 5 mm can be used for this main body 2. On the outside of the main body 2, a support member 11 is provided, which is made up of a ring member 12 arranged on the outer periphery of the main body 2 and a rod-like member 13 connected to the ring member 12 and having a needle-like tip. By moving the ring member 12 along the outer periphery of the main body 2 in the vertical direction Y, the support member 11 can be freely moved in the vertical direction Y.

[0018] A holder 14 is attached to the lower end of the main body 2. This holder 14 is used to tilt the spraying device 1 onto a mounting surface. As shown in FIG. 3(a), the holder 14 has a cylindrical upper member 15 and a hollow lower member 16 that is connected to the lower side of the upper member 15. As shown in FIG. 3(b), the front portion of the lower end of the lower member 16 is cut out at an angle to form a curved portion (angle changing portion) 17. When the spraying device 1 is fixed to the mounting surface, the entire curved portion 17 comes into contact with the mounting surface. The fixing angle of the spraying device 1 is determined by the angle of the curved portion 17, and this angle is set to 60 degrees, for example.

[0019] [Spray agent housing] The spray agent housing 3 is made of resin and has an exposed portion 20 that forms the upper side of the spray agent housing 3, and a storage portion 21 that is connected to the exposed portion 20 and forms the lower side of the spray agent housing 3. The exposed portion 20 and the storage portion 21 are formed as a single unit. The exposed portion 20 has an outer shape that is larger than the outer shape of the storage portion 21, and a stepped portion 22 is formed. The spray agent housing 3 is fixed to the main body 2 by inserting the storage portion 21 into the main body 2 and abutting the stepped portion 22 against the upper end of the opening of the main body 2. Therefore, the exposed portion 20 is positioned outside the main body 2. A spiral groove is formed on the outer periphery of the exposed portion 20, and a cap 23 is attached to the exposed portion 20.

[0020] [cap] The cap 23 has a circular injection hole 24 in the center of its top surface, and a spiral groove formed on the inside. The cap 23 is attached so as to cover the opening of the exposed portion 20 by screwing the groove of the cap 23 into the groove of the exposed portion 20. An injection hole plug 25 is attached to the injection hole 24, and the injection hole plug 25 closes the injection hole 24. The cap 23 is made of, for example, polypropylene, and the injection hole plug 25 is made of, for example, polyethylene.

[0021] [Spray agent storage section] The spray agent storage section 4 is bag-shaped and is made of, for example, polyethylene or vinyl. The spray agent storage section 4 is filled with a pseudo-reagent (spray agent) 4A. The pseudo-reagent used may be liquid or powder, for example, polyethylene glycol. A piston (elastic body) 10 is provided between the spray agent storage section 4 and the bottom of the storage section 21 of the spray agent housing 3. The spray agent storage section 4 is placed directly on top of the piston 10.

[0022] [Fuse holder] The fuse holder 5 is provided inside the main body 2 facing in the vertical direction Y, with its upper tip connected to the lower end of the spray housing 3 (Figure 1). A recess is formed at the upper end of the fuse holder 5, and this recess is filled with explosives 9. 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 spaced a certain distance from the explosives 9. The length of the fuse 5A is 6 to 7 cm.

[0023] [Ignition device] The ignition device (ignition unit) 6 has a detonator holder 30, a detonator 31 attached to the lower end of the detonator holder 30, a firing pin tube 32 connected to the underside of the detonator holder 30, a firing pin spring 33 attached inside the firing pin tube 32, a firing pin 34 attached 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 and the firing pin 34 hits the detonator 31, causing ignition.

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

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

[0026] First, the top lid 7 and the cap 23 or the spray hole plug 25 are removed, and the pseudo-reagent 4A is filled into the bag-shaped spray agent storage section 4. The amount of pseudo-reagent to be filled is determined appropriately, taking into consideration the amount to be sprayed and the spray area. After filling with the pseudo-reagent 4A, the cap 23 or the spray hole plug 25 is reattached. Next, the bottom lid 8 is removed, the curved portion 17 of the holder 14 is brought into contact with the mounting surface, and the spray device 1 is placed at an angle relative to the mounting surface. Thereafter, as shown in Figure 4, the rod-shaped member 13 is slid downwards on the main body 2, the tip of which is inserted into the mounting surface, and the spray device 1 is fixed to the mounting surface and installed.

[0027] After installing the spraying device 1, the dummy reagent 4A is sprayed. Specifically, the firing pin 35 is pulled out, and the firing pin 34 is forcefully struck against the detonator 31, igniting the lower end of the fuse 5A. This causes the fuse 5A to burn from the bottom to the top, igniting the explosive 9. When the explosive 9 is ignited, the combustion pressure of the explosive 9 pushes the piston 10 upward, compressing the spraying agent container 4. This compression force causes the ejection hole plug 25 to fly out of the cap 23, and the dummy reagent 4A is ejected from the ejection hole 24 to the outside, where it is sprayed over the desired area.

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

[0029] The spraying device 1 of this embodiment is equipped with a piston 10 disposed between the explosive 9 and the spraying agent storage section 4. When the explosive 9 is ignited, the combustion pressure causes the piston 10 to press against the spraying agent storage section 4, releasing and spraying the pseudo-reagent 4A outside the spraying device 1. The spraying device 1 of this embodiment sprays the pseudo-reagent 4A using the pressing force of the piston 10, thereby enabling uniform spraying without causing the main body 2 to explode. This makes the spraying device 1 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 piston 10 is positioned below the spraying agent housing 3, isolating the explosive 9 from the spraying agent storage section 4, and thus preventing a reaction between the explosive 9 and the pseudo-reagent 4A.

[0030] In the spraying device 1 according to this embodiment, the 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 when the through-hole 5B is formed below the position of the lower end of the fuse 5A or when no through-hole 5B is formed, the fuse 5A is more easily ignited, and the spraying operation of the spraying device 1 is more stable.

[0031] The spraying device 1 according to this embodiment has a holder 14 at the lower end of the main body 2. A curved portion 17 is formed at the lower end of this holder 14, which allows the angle of the spraying device 1 relative to the mounting surface to be adjusted. Therefore, by placing 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 in which an injection hole 24 is formed, and an injection hole plug 25 is attached to this injection hole 24. After filling the spray agent storage section 4 with the pseudo-reagent 4A, by attaching the injection hole plug 25, it is possible to prevent the pseudo-reagent 4A from leaking out 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 can move 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 comprises an upper lid 7 attached to the cap 23, and a lower lid 8 formed with an insertion portion 8A. By attaching the upper lid 7, the spraying agent housing 3 and the cap 23 can be protected, and by attaching the lower lid 8, the holder 14 can be protected. Furthermore, 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 a number of uses, including, for example, displaying the situation in areas contaminated by chemical agents and using it for training defense forces, particularly chemical attack response training using chemical agent detectors.

[0036] Although the present embodiment has been described above, it is possible to select and / or change the configurations given in the above embodiment to other configurations as appropriate without departing from the spirit of the present invention.

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