  The problem to be solved is that when there is no cap (10) as in the prior art and the discharge port of the extinguishing agent is left exposed, oil or dust is discharged from the discharge port by leaving it in the kitchen for a long time. The discharge port is clogged by adhering to the surface, and in the event of an emergency, a discharge failure occurs due to the clogging of the discharge port, and it cannot be used for initial fire fighting.

  The present invention comprises a fire extinguisher release mechanism comprising a mechanism frame fixed to a base of a fire extinguisher storage container, and an inverted L-shaped discharge pipe inserted into the mechanism frame so as to be lowered. When the discharge pipe is pushed down, the lower end of the discharge pipe pushes open the valve part of the extinguishing agent storage container so that the extinguishing agent is discharged sideways from the front end of the discharge pipe. The upper front part of the body is bent downward to form a clogging prevention cover part, and this clogging prevention cover part normally closes the tip end of the discharge pipe and discharges when the discharge pipe is lowered (release) It is characterized in that the tip end of the tube is detached from the clogging prevention cover portion.

  In the present invention, since the clogging prevention cover portion of the mechanism frame always closes the distal end of the discharge pipe, oil or dust does not adhere to the distal end of the discharge pipe and the distal end is not clogged. Therefore, there is an effect that there is no emission obstacle at the time of use (release) and it can be used for initial fire extinguishing.

  Realized by installing a fire extinguishing agent release mechanism inside the mechanism frame, providing a clogging prevention cover at the upper front of the mechanism frame, and always closing the tip of the discharge pipe with this clogging prevention cover did.

  An embodiment of the present invention will be described with reference to FIGS. 1 is a longitudinal side view showing a normal state, FIG. 2 is a view of FIG. 1 viewed from the front, FIG. 3 is a longitudinal side view showing a state where the lock is released from FIG. 1, and FIG. 4 is a state radiating from FIG. FIG. 5 is a view of FIG. 4 as viewed from the front.

The vertical cylinder 5 is inserted into the mechanism frame 3 so as to be able to swing back and forth, and the lower end 6 is inserted into the vertical cylinder 4 and the front end 7 is prevented from clogging the mechanism frame 3. An inverted L-shaped discharge tube comprising a horizontal tube portion 5b abutting against the cover portion 8, 9 is a spring that always pushes down the discharge tube 5 in the vertical direction, and 10 is a lower portion 10a behind the discharge tube 5 in the mechanism frame 3. The upper push button is inserted so that the upper part swings back and forth with the fulcrum as the fulcrum 10b is a locking member that protrudes from the rear surface of the mechanism frame 3, 11 is a receiving bar that is provided on the locking member 10 to receive the convex portion 12 of the discharge pipe 5 from below, and 13 is provided on the inner surface of the mechanism frame 3. A claw for holding the front surface of the lock member 10 from the front, and 14 swings forward and backward with the upper part (not shown) as a fulcrum in front of the discharge pipe 5 in the mechanism frame 3, that is, inside the L-shape of the discharge pipe 5. The discharge lever 15 is inserted in the manner described above, 15 is a drive portion that protrudes from the rear surface of the discharge lever 14 and has a cam surface 15a for pushing down the vertical tube portion 5a of the discharge tube 5, and 16 is a vertical tube portion of the discharge tube 5. A driven member provided on 5a and driven by the cam surface 15a of the drive unit 15 and descending along the guide 17, 18 is a protrusion provided on the lower surface of the release lever 14, and is provided in the hole of the base 3a of the mechanism frame 3. Lock to configure the lever locked state It has become.

  In the normal state shown in FIG. 1, the upper end of the front surface of the lock member 10 is locked to the claw 13 and the lock member 10 is fixed in the arch frame portion 3b. 11 and the release lever 14 is not grasped by the drive unit 15 being prevented from swinging backward (gripping direction) by the driven member 16. In other words, in this state, the discharge tube 5 and the release lever 14 are solidified by the lock member 10 and are held in a state where the release lever 14 cannot be operated.

  Further, in the normal state shown in FIG. 1, the clogging prevention cover part formed by bending the upper front part of the arch frame part 3 b of the mechanism frame body 3 with the tip end 7 of the discharge pipe 5 bent downward as shown in FIG. 2. 8, oil or dust does not adhere to the tip port 7 of the discharge pipe 5 and the tip port 7 is not clogged, so that there is no discharge obstacle during use (release). Can be used for initial fire fighting.

  In the unlocked state shown in FIG. 3, the push bar portion 10 b of the lock member 10 is pushed in, the front upper end of the lock member 10 is detached from the claw 13 and swings forward, whereby the receiving bar 11 is moved from the convex portion 12. Since it is detached, the discharge pipe 5 is slightly lowered by the force of the spring 9 and its lower end 6 is on the valve shaft (part) 2. That is, in this state, the release lever 14 can be operated at any time.

  In the state of radiation shown in FIG. 4, when the discharge lever 14 is grasped and the driven member 16, that is, the discharge pipe 5 is pushed down by the cam surface 15a, the valve shaft (part) 2 is pushed open at the lower end port 6 thereof. Therefore, the fire extinguisher in the fire extinguisher storage container 1 radiates from the front end 7 through the discharge pipe 5.
