The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following description, in conjunction with the accompanying drawings, describes a portable dry powder fire extinguisher for adjusting the spray size according to an embodiment of the present invention.

[0025] As shown in Figures 1 to 6, a portable dry powder fire extinguisher for adjusting the spray size according to an embodiment of the present invention may include a storage bucket 1, a carrying strap 2, a fire extinguishing bottle 3, a spray hose 4, a pressing handle 5, and an adjustment component 6.

[0026] The carrying strap 2 is installed on the storage bucket 1, the fire extinguishing bottle 3 is installed inside the storage bucket 1, one end of the spray hose 4 is connected to the fire extinguishing bottle 3, the other end is connected to the adjustment component 6, and the pressing handle 5 is installed on the other end of the spray hose 4.

[0027] It should be noted that a pressure gauge is installed on fire extinguisher bottle 3 to display the internal pressure status of fire extinguisher bottle 3, thus making it easier for users to observe.

[0028] It should be noted that fire extinguisher bottle 3 is equipped with a control valve, which allows users to control the release of the extinguishing agent.

[0029] The adjustment assembly 6 includes: a mounting tube 61, a connector 62, an adjustment plate 63, and a limiting device 64.

[0030] The installation pipe 61 is installed on the other end of the spray hose 4, the connector 62 is installed on the installation pipe 61, the adjusting plate 63 is engaged in the connector 62, and the limiting device 64 is rotatably installed on the connector 62, and the limiting end of the limiting device 64 is engaged with the limiting end of the adjusting plate 63.

[0031] The connector 62 consists of a plate 621, a curved plate 622, and a ring 623.

[0032] Among them, a plate 621 is set on the mounting pipe 61 on the side away from the spray hose 4, and a hole 6211 is opened on the plate 621 and connected to the mounting pipe 61. A curved plate 622 is connected to the plate 621 and a ring 623 and is located at the edge of the plate 621 and the ring 623. A first annular groove 6231 and a second annular groove 6232 are opened sequentially from the outside to the inside on the side of the ring 623 away from the curved plate 622.

[0033] It should be noted that a plurality of ring-shaped limiting grooves 6212 are provided on the plate 621 near the curved plate 622, and are coaxial with the plate 621 respectively. A plurality of ring-shaped limiting blocks 633 are provided on the adjusting plate 63 near the plate 621, and are respectively limited in each limiting groove 6212, so that the limiting blocks 633 are limited by the limiting grooves 6212, thereby limiting the adjusting plate 63 and preventing it from rotating.

[0034] It should be noted that the limiting block 633 is made of rubber, which makes it easy for the limiting block 633 to engage in the limiting groove 6212.

[0035] It should be noted that the adjusting plate 63 is engaged between a plate 621 and a ring 623, and the adjusting plate 63 on the side away from the plate 621 is provided with a plurality of first locking teeth 631. The adjusting plate 63 is provided with a plurality of two holes 632 distributed in a ring at equal intervals, and is located between the plurality of first locking teeth 631. A hole 6211 is connected to one of the two holes 632. On the one hand, by providing the first locking teeth 631, it is easy to limit the second locking teeth 6451 on the first locking teeth 631, thereby preventing the adjusting plate 63 from detaching from the connector 62. On the other hand, the cooperation between the one hole 6211 and the two holes 632 facilitates the transmission of extinguishing agent.

[0036] The limiting device 64 includes: a second ring 641, a telescopic rod 642, a third ring 643, a spring 644, and a second plate 645.

[0037] The second ring 641 rotates within the second annular groove 6232. Multiple telescopic rods 642 are respectively mounted on the second ring 641 and located within the first annular groove 6231. The telescopic ends of the multiple telescopic rods 642 are respectively connected to the third ring 643. Multiple springs 644 are respectively sleeved on the multiple telescopic rods 642, and the two ends of the multiple springs 644 are respectively connected to the second ring 641 and the third ring 643. One end of the second plate 645 is located within the third ring 643, and the other end is in contact with the adjusting plate 63. Multiple second locking teeth 6451 are provided on the other end of the second plate 645, and are respectively engaged within multiple first locking teeth 631. Multiple three holes 6452 are provided on the second plate 645 in an annular shape with equal spacing, and are respectively connected to each two hole 632.

[0038] It should be noted that the diameters of each two-hole 632 and each three-hole 6452 are different, which facilitates the adjustment of the spray size of the extinguishing agent.

[0039] Preferably, each of the three holes 6452 is equipped with a filter plate (not shown in the figure) to make the extinguishing agent more evenly distributed and improve the extinguishing effect.

[0040] Specifically, when this utility model is needed, the user first holds the carrying strap 2 with one hand and the spray hose 4 with the other hand, and opens the control valve. Then, by pressing the handle 5, the extinguishing agent in the fire extinguishing bottle 3 is sprayed out sequentially along the spray hose 4, the installation pipe 61, the first hole 6211, the second hole 632 and the third hole 6452 to carry out fire extinguishing work.

[0041] It should be noted that when the spray size needs to be adjusted, by rotating the three rings 643, the second plate 645 and multiple second locking teeth 6451 are rotated in sequence, which in turn rotates the multiple first locking teeth 631 that are engaged with it, thereby rotating the adjusting plate 63, which in turn connects another two-hole 632 and three-hole 6452 with one-hole 6211. At the same time, the three rings 643 drive multiple telescopic rods 642, multiple springs 644 and two rings 641 to rotate in sequence. At this time, the user can perform fire extinguishing work by pressing the handle 5.

[0042] In summary, the portable dry powder fire extinguisher for adjusting the spray size according to the present utility model embodiment, through the cooperation between the connector 62, the adjusting plate 63 and the limiting device 64, facilitates the adjustment of the spray size, thereby avoiding the waste of extinguishing agent when facing different fire situations. On the other hand, it facilitates the disassembly of the adjusting plate 63, thereby facilitating the cleaning and maintenance of the various components of the adjusting assembly 6 in the later stage. Moreover, it is portable and highly practical.
