DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to the field of an injection nozzle device for both automatic and manual injection in a fire extinguisher.

[Prior Art] As a conventional fire extinguisher, there is one that detects a high temperature in a room through a temperature sensor device and ejects a fire extinguishing liquid automatically or manually, but an injection nozzle attached to the fire extinguisher. Whether the device is an automatic injection or a manual injection, one injection nozzle had to be jointly used.

Therefore, especially when using the automatic injection type, even if the fire extinguisher is installed in a predetermined place in the room where it is easy to install, it is possible to adjust the injection nozzle to an angle suitable for automatic fire extinguishing suitable for the room. It was hard to get along. Therefore, there is a defect that even if the fire extinguishing liquid is automatically injected, the fire extinguishing liquid is thoroughly ejected into the entire room and the fire extinguishing activity is not performed.

[Problems to be Solved by the Invention] A jet nozzle device mounted on a conventional automatic / manual fire extinguisher device is capable of performing 1
The individual injection nozzles had to be jointly used.
Therefore, even if the fire extinguisher is attached to a place where it is easy to attach the fire extinguisher in a predetermined place in the room, it is difficult to adjust the injection nozzle to an angle suitable for automatic fire extinguishing suitable for the room. Therefore, even if the fire-extinguishing liquid is automatically injected, there is a defect that the fire-extinguishing liquid does not spread over the entire room and the fire-extinguishing activity is not performed.

However, in the case of the present invention, in the case of manual injection, the fire extinguishing liquid is ejected in a straight line, and in the case of automatic injection, it is operated downward so that the fire extinguishing liquid can be thoroughly ejected into the entire room. It was done.

[Means for Solving the Problems] A fire extinguisher device of the present invention is a bazooka type tubular body in which a plastic tank filled with a fire extinguishing liquid can be put in and out, and an outer portion of the tubular body communicates with the inside of the tubular body. A joint part for mounting, a temperature sensor with a pressure firing mechanism for ejecting a high-pressure incombustible liquid, a trigger device for manually operating the temperature sensor, a rear plate fitted in a rear opening of the cylinder, and a front part of the cylinder. In a fire extinguisher having a front plate for penetrating a rear nozzle in an opening, an outer peripheral portion has a circumferential shape, and a blocking portion for blocking the through hole communicating with the through hole is provided at a predetermined position, and the blocking portion is a boundary. A front nozzle having injection switching holes formed on both left and right sides is fixed to the rear nozzle, the outer peripheral portion of the front nozzle is slid by a predetermined distance, and a shielding portion for shielding the front injection switching hole is provided inside and the shielding portion. Place a little space from the part A rear shield part is formed at the open position, a recess and an opening communicating with the recess are formed between both shield parts, and a slide part between the O-ring fitted inside the front part and the shield part is formed. A slide portion having a concave portion is inserted into the front nozzle, and one end portion has an opening portion connected to the above-described opening portion, and the other end portion has an opening portion having a diameter slightly larger than the above-mentioned opening portion, An automatic injection nozzle part in which a back plate, a spray body and an injection port are fitted in the side body that is screwed into the opening part of the slide part is screwed into the opening part of the slide part, and is inserted into the vacant chamber part of the cap having the injection hole. It is an injection nozzle device for both automatic and manual injection in a fire extinguisher, characterized in that, after inserting the spray plate, a manual injection nozzle part having a fixed part and a fixed part is screwed to the front nozzle part.

[Operation] As a first operation of the present invention, a process when the fire extinguisher equipped with the injection nozzle device of the present invention automatically injects the fire extinguishing liquid will be described as follows. That is, the slide portion fitted into the front nozzle is slid until the tip of the slide portion reaches the rear end of the manual injection nozzle portion. As a result, the state shown in FIG. 8 is reached and the slide portion stops. By sliding the slide part as described above, the outflow to the manual injection nozzle part is blocked by the blocking part, and the extinguishing liquid flows out in the direction of the automatic injection nozzle part that rotates 360 degrees, It is in the state of automatic injection. When the fire extinguisher of the present invention is hung, or when a fire or the like occurs in the room where the fire extinguisher is placed, the inside of the ship, etc., reaches a predetermined temperature, for example, 7 ° C ± 5 ° C, For example, the operating rod changes from a bent shape to a linear shape, and at the moment when the linear movement gradually starts to change, the tip of the operating rod catches the tip of the arm and moves the arm upward. lift. In the process of such an operation, the rear end of the arm fitted into the arm receiver serves as a fulcrum to lift the arm upward, and the plate attached to the arm is also attached to the arm. At the same time as being proportionally gradually lifted upward, the set pins inserted into the respective small holes are removed in proportion to the upward movement of the arm and the plate, and are removed from the respective small holes.

At the moment when the set pin is pulled out as described above, the roller pin with the pin as a fulcrum, the central roller that is in contact with the recess is forcibly rotated inward, and the center pin contacts the upper surface of the base. The left and right rollers on both sides rotate outward in the direction opposite to the rotation of the central roller and deploy in the outward direction. At the moment the roller pin is deployed, the explosive force of the spring causes the firing pin to plunge downward, and the pointed portion of the tip that constitutes the firing pin breaks the sealing slope of the cylinder.

When the cylinder is broken and the high-pressure incombustible liquid filled in the cylinder is ejected by the above steps, the liquid passes through the joint portion and flows out into the cylinder. Then, the liquid that has flowed out presses the flexible plastic tank, and the automatic injection nozzle unit that constitutes the injection nozzle device that is set so that the fire extinguishing liquid filled in the plastic tank is automatically injected, Is jetted. The automatic injection angle at that time is 360 degrees.

When the injection of the fire-extinguishing liquid is completed automatically, remove the rear plate that covers the rear opening of the cylinder, pull out the empty plastic tank from the injection nozzle device, and remove the tip of the stock plastic tank from the above. Fit into the injection nozzle device.
Then, the rear plate is covered with the rear opening of the cylindrical body. Then push the cover stopper to open the cover and pull out the used temperature sensor from the joint.
Then, the rear portion of the new temperature sensor is fitted into the joint portion, and then the cover portion is restored to the normal cover state. The time required for the above operation is extremely short. Therefore, one fire extinguisher can be used any number of times if the plastic tank and temperature sensor are stocked.

Next, as a second action, the order in which the fire extinguisher ejects the fire extinguishing liquid by the manual method will be described as follows.

That is, the slide portion, which has been slid with the front end in an adhered state, is pulled toward the rear end of the manual injection nozzle. As a result, the rear end of the slide portion hits the nut and stops as shown in FIGS. In this stopped state, the concave portion and the opening portion are shielded by the automatic injection nozzle portion, and the outflow route of the fire extinguishing liquid is cut off. On the other hand, both of the injection switching holes and the recesses are in communication with each other, and the extinguishing liquid is ready for injection from the manual injection nozzle. Then, with the fire extinguisher of the present invention, hold your finger on the trigger part in the same way as when you hold the bazooka gun with your left hand. The tip of the pressing rod connected to the trigger part presses the switch part mounted on the head of the temperature sensor, and the set pin connected to the switch part is pulled out from the small hole. At the moment when the set pin is pulled out, the roller pin is in contact with the recess with the pin as a fulcrum, the central roller is forced to rotate inward, and the left and right side rollers that are in contact with the upper surface of the base part Rotates outward in the direction opposite to the rotation of the central roller and expands outward. At the moment the roller pin is deployed, the explosive force of the spring causes the firing pin to plunge downward, breaking the pointed portion of the tip that constitutes the firing pin of the cylinder sealing plate.

When the cylinder is broken and the high-pressure incombustible liquid filled in the cylinder is ejected by the above steps, the liquid passes through the joint portion and flows out into the cylinder. The liquid that has flowed out presses the flexible plastic tank, and the fire extinguishing liquid filled in the plastic tank is switched from the automatic injection function to the manual injection function so that it can be operated manually. Injection is made from the department.
The injection angle in the manual injection at that time is a linear direction. When the injection of fire-extinguishing liquid is completed, remove the rear plate that covers the rear opening of the cylinder, pull out the empty plastic tank from the injection nozzle device, and remove the tip of the stock poly tank from the injection nozzle device described above. Fit in. Then, the rear plate is covered with the rear opening of the cylindrical body. Then push the cover stopper to open the cover and pull out the used temperature sensor from the joint. Then, the rear part of the new temperature sensor is fitted into the joint part, and then the cover is restored to the normal cover state. The time required for the above operation is extremely short. Therefore, if the plastic tank and temperature sensor are stocked, only one stock can be reused with one fire extinguisher.
