The dry powder in the dry powder fire extinguisher is not easy to spray out, and the dry powder cannot be sprayed quickly, thereby affecting the fire extinguishing efficiency of the fire extinguisher. Utility Model Content

[0005] The purpose of this application is to address the above-mentioned technical problems and provide a fast-spraying fire extinguishing device, which can evenly and quickly stir the dry powder in the dry powder fire extinguisher when the dry powder fire extinguisher needs to be used to extinguish a fire after being left stationary for a long time. The stirring efficiency is high and the stirring effect is good, avoiding the situation where the dry powder in the dry powder fire extinguisher is difficult to spray out, so that the dry powder fire extinguisher can quickly spray dry powder, thereby improving the fire extinguishing efficiency of the fire extinguisher.

[0006] The present application provides a rapid-spray fire extinguishing device, comprising a fire extinguisher body and:

[0007] A dry powder chamber, the dry powder chamber being arranged on the fire extinguisher body;

[0008] A drive assembly, wherein the drive assembly is mounted on the fire extinguisher body;

[0009] A stirring assembly, wherein the stirring assembly is mounted on the driving assembly;

[0010] A powder suction pipe, the powder suction pipe is installed on the fire extinguisher body;

[0011] Among them, the stirring assembly includes a hollow cylinder, a rotating disk, a tube hole, a rotating cylinder, and a first stirring blade. The hollow cylinder is installed on the driving assembly, the rotating disk is installed on the hollow cylinder, the rotating cylinder is installed on the rotating disk, the tube hole is arranged on the rotating disk, the first stirring blade is installed on the rotating cylinder, and several first stirring blades are provided.

[0012] When a fire extinguisher is needed to extinguish a fire, the driving assembly drives the hollow cylinder to rotate, and the rotation of the hollow cylinder drives the rotating disk to rotate. The tube hole can allow the powder suction tube to pass through the rotating disk. When the rotating disk rotates, it drives the rotating cylinder to rotate. The rotation of the rotating cylinder drives several first stirring blades on the rotating cylinder to rotate. The rotation of the first stirring blades can stir the dry powder in the fire extinguisher evenly and quickly, avoiding the situation that the dry powder in the dry powder fire extinguisher is difficult to spray out, so that the dry powder fire extinguisher can quickly spray dry powder, thereby improving the fire extinguishing efficiency of the fire extinguisher.

[0013] Furthermore, the stirring assembly further comprises:

[0014] Mounting holes, wherein the mounting holes are provided on the rotating disk, and a plurality of the mounting holes are provided;

[0015] A bearing, wherein the outer ring of the bearing is mounted on the mounting hole;

[0016] A stirring rod, wherein the stirring rod is mounted on the inner ring of the bearing;

[0017] a second gear mounted on the stirring rod;

[0018] A gear ring, the gear ring is mounted on the dry powder chamber and cooperates with the second gear;

[0019] The second stirring blade is installed on the stirring rod, and a plurality of the second stirring blades are provided.

[0020] When the rotating cylinder rotates, the second gear is driven to rotate on the ring gear around the axis of the rotating cylinder. At this time, the rotation of the second gear drives the stirring rod to rotate on the bearing. At this time, the several second stirring blades on the stirring rod can stir the dry powder in the fire extinguisher. The stirring rod and the rotating cylinder have different rotation speeds and rotate at the same time, so that the first stirring blade and the second stirring blade stir the dry powder separately, further expanding the stirring range of the dry powder and improving the stirring effect of the dry powder.

[0021] Furthermore, the stirring assembly further comprises:

[0022] A drive box, the drive box is mounted on the fire extinguisher body, and the drive assembly is mounted on the drive box;

[0023] A rotating shaft is mounted on the drive box and is provided with a through hole for the powder suction tube to pass through;

[0024] a first gear mounted on the rotating shaft;

[0025] a rack mounted on the drive assembly;

[0026] A reset component is installed on the drive box.

[0027] When the hollow cylinder needs to be driven to rotate, the driving component drives the rack to move, and the rack cooperates with the first gear. When the rack is displaced, it drives the first gear to rotate. The first gear is installed on the rotating shaft, and the rotating shaft is driven by the first gear to rotate while driving the hollow cylinder to rotate. The rack and the gear cooperate to drive the hollow cylinder to rotate to perform stirring. When the reset component drives the rack to reset, it can also drive the hollow cylinder to rotate, so that the rotation of the hollow cylinder drives the first stirring blade and the second stirring blade to perform stirring more conveniently and efficiently.

[0028] Furthermore, the driving assembly includes:

[0029] a compression spring mounted on the drive box;

[0030] a first moving block, the first moving block being mounted on a compression spring;

[0031] a lock hole, the lock hole being arranged on the rack;

[0032] A pull ring is inserted into the lock hole.

[0033] The compression spring is in a compressed state when the pull ring is inserted into the keyhole. When the driving component needs to drive the rack to move, the user pulls out the pull ring inserted in the keyhole on the rack. After the pull ring is pulled out, the rack loses its limit and is pushed by the rebound force of the compression spring to move, driving the first gear to rotate. The user only needs to pull out the pull ring to stir the dry powder in the fire extinguisher, making it more convenient and efficient for the user to stir the dry powder in the fire extinguisher.

[0034] Furthermore, the reset component includes:

[0035] A jack, the jack being provided on the drive box;

[0036] A reset rod, which is inserted into the socket;

[0037] a second moving block, the second moving block being mounted on the reset rod;

At this time, the user can use the fire extinguisher to spray dry powder to extinguish the fire. When the fire extinguishing is completed, the user pushes the reset rod inward, and the reset rod is inserted into the socket. The reset rod is pushed inward and drives the second moving block to move toward the end where the rack is provided until the user holds the reset rod to drive the second moving block to push the rack to complete the reset. After the rack is reset, the user reinserts the pull ring into the lock hole to complete the locking. The reset assembly allows the rack to be reset after driving the first gear to complete the rotation, so that the dry powder can be stirred again when the fire extinguisher needs to be used next time.

[0040] Furthermore, the first stirring blade is provided with a filter hole, and there are a plurality of filter holes.

[0041] The first stirring blade is provided with a plurality of filter holes. When the first stirring blade is driven to rotate around the axis of the rotating cylinder to stir the dry powder in the dry powder chamber, the filter holes can reduce the resistance of the first stirring blade when stirring the dry powder, making it easier to drive the first stirring blade to stir.

[0042] The beneficial effects of this application are:

[0043] 1. The rotation of the first stirring blade can evenly and quickly stir the dry powder in the fire extinguisher, thereby preventing the dry powder in the dry powder fire extinguisher from being difficult to spray out, allowing the dry powder fire extinguisher to spray dry powder quickly, thereby improving the fire extinguishing efficiency of the fire extinguisher;

[0044] 2. The stirring rod and the rotating drum rotate at different speeds and simultaneously, so that the first stirring blade and the second stirring blade stir the dry powder separately, further expanding the stirring range of the dry powder and improving the stirring effect of the dry powder;

[0045] 3. The user only needs to pull out the pull ring to stir the dry powder in the fire extinguisher, which makes it more convenient and efficient for the user to stir the dry powder in the fire extinguisher. BRIEF DESCRIPTION OF THE DRAWINGS
