[0020] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] For example, Figure 1As shown, a new type of portable dry powder fire extinguisher, including fire extinguisher body 1, the upper side of the fire extinguisher body 1 is provided with a spray port, the spray port is fixedly connected with a connecting pipe 15, one side of the connecting pipe 15 is fixedly connected with an outer tube 12, one side of the outer tube 12 is fixedly connected with a hose 4, the outer tube 12 is installed with a spray port adjusting group, one side of the fire extinguisher body 1 is fixedly connected with a support 3;

[0022] In use, the user starts the dry powder fire extinguisher by pressing the switch, at this time the dry powder in the fire extinguisher body 1 will be transmitted to the outer tube 12 through the spray port, then the spray port adjusting group adjusts the spray flow and pressure of the dry powder, at this time the dry powder will be transmitted to the hose 4 through the outer tube 12, and then sprayed out of the hose 4, thereby extinguishing the fire source, reducing the waste of dry powder, making the dry powder more accurately cover the fire source, and improving the fire extinguishing efficiency;

[0023] At the same time, the appropriate pressure can ensure that the dry powder is sprayed at an appropriate speed and range, and when extinguishing a fire source far away, the range of the dry powder can be increased by adjusting the pressure, so that the dry powder can reach the fire source. At the same time, pressure adjustment is also helpful for effective fire extinguishing at different distances. When the distance from the fire source is short, the pressure can be reduced to avoid the dry powder from blowing away the flame due to excessive impact, causing the fire to spread. When the distance from the fire source is far, increasing the pressure can ensure that the dry powder can be sprayed to a far enough distance.

[0024] As shown in Figure 2 , Figure 3 , Figure 4 The spray port adjusting group includes a first circular plate 8, the first circular plate 8 is fixedly connected to one side of the inner side of the outer tube 12, a rotating shaft 10 is fixedly connected to the center position of the first circular plate 8, the rotating shaft 10 is rotatably connected with a second circular plate 9, the second circular plate 9 is rotatably connected to the outer side of the rotating shaft 10, a plurality of fixed discharge holes are formed in the first circular plate 8, a plurality of movable discharge holes are formed in the second circular plate 9, the plurality of fixed discharge holes and the plurality of movable discharge holes are one-to-one corresponding, and a rotating adjusting mechanism connected with the second circular plate 9 is installed on the outer tube 12;

[0025] In use, when the second circular plate 9 is in the initial position, the fixed discharge holes and the movable discharge holes completely coincide or have a large area of coincidence, at this time the dry powder can be sprayed out of the spray port with a large flow, by rotating the second circular plate 9 through the rotating adjusting mechanism, the overlapping area of the movable discharge holes and the fixed discharge holes gradually decreases, when rotated by a certain angle, part of the movable discharge holes and the fixed discharge holes are staggered, the dry powder spraying channel is narrowed, the flow is reduced, continue to rotate, the overlapping area is further reduced, the flow will continue to decrease, until the two are completely staggered, at this time the dry powder is almost impossible to pass through, realizing accurate adjustment of the dry powder spray flow in the fire extinguisher body 1, improving the fire extinguishing efficiency.

[0026] As shown in Figure 1 , Figure 5As shown, the support 3 comprises a crossbar fixedly connected to one side of the fire extinguisher body 1, one end of the crossbar is provided with a rotating cavity, a vertical rod is rotatably arranged in the rotating cavity, a threaded hole is formed in one side of the crossbar, a screw 17 is threadedly connected in the threaded hole, one end of the vertical rod is fixedly connected with a connecting piece, when in use, the user adjusts the crossbar and the vertical rod to a suitable position, and then tightens the screw 17, the head of the screw 17 abuts against the vertical rod, so that the vertical rod cannot rotate freely, thereby ensuring the stability of the support 3 during use.

[0027] As shown in Figure 1 , Figure 5 , the connecting piece comprises a pipe clamp 6 fixedly connected to the vertical rod, and the hose 4 is clamped in the pipe clamp 6, when in use, the hose 4 is clamped outside the pipe clamp 6, the user only needs to hold the fire extinguisher body 1 with one hand to operate, thereby reducing the fatigue burden caused by using both hands for a long time, and improving the endurance and persistence of fire extinguishing operation.

[0028] As shown in Figure 1 , a circular groove is formed in the outer tube 12, the rotating adjusting mechanism comprises a worm 18 rotatably connected in the circular groove, a circular rod 11 is fixedly connected to the upper side of the worm 18, one end of the circular rod 11 extends to the outside of the outer tube 12, a second circular plate 9 is fixedly connected with a worm wheel 16 outside, the worm wheel 16 is engaged with the worm 18, when in use, the circular rod 11 is rotated to drive the worm 18 to rotate in the circular groove, since the worm 18 is engaged with the worm wheel 16 fixedly connected to the outside of the second circular plate 9, the rotation of the worm 18 drives the worm wheel 16 to rotate, the overlapping area of the movable discharge hole on the second circular plate 9 and the fixed discharge hole on the first circular plate 8 gradually changes, thereby realizing the adjustment of the dry powder injection flow from large to small; when the circular rod 11 is reversely rotated, the overlapping area reversely changes, realizing the adjustment of the flow from small to large, and ensuring the stability and reliability of the rotation of the second circular plate 9.

[0029] As shown in Figure 1 , a plurality of fluorescent rings 7 are fixedly connected to the outside of the fire extinguisher body 1, when in use, in the case of dark light or emergency, such as power failure caused by fire, smoky environment, the fluorescent ring 7 can emit fluorescence, this fluorescence effect can last for a period of time in the dark, providing obvious visual indication for finding the fire extinguisher, so that people can quickly find its position when they need to use it in daily inspection.

[0030] The working principle of the utility model is: when using, the user presses the handle part of the switch, at this time the dry powder in the fire extinguisher main body 1 is transmitted to the outer pipe 12 through the injection port, then the injection port adjusting group adjusts the injection flow and angle of the dry powder, at this time the dry powder is transmitted to the hose 4 through the outer pipe 12, and then is sprayed out by the hose 4, and then the fire source is extinguished, the waste of the dry powder is reduced, simultaneously, the injection port adjusting group can also adjust the angle range of injection, so that the dry powder can more accurately cover the fire source, and the fire extinguishing efficiency is improved.

[0031] The above is only the preferred embodiment of the utility model, and it should be pointed out that for the ordinary skilled in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
