[0021] See also Figure 1-Figure 3A fire extinguisher with adjustable spraying area includes a fire extinguisher 1, an outer ring of a nozzle of the fire extinguisher 1 is fixedly sleeved with a sleeve 2, the four corners of the outer wall of the sleeve 2 are chamfered, and a gripping groove is evenly provided on the left side of the sleeve 2, so as to improve the gripping comfort of the sleeve 2, an elastic card seat 11 is fixedly provided on the right side of the fire extinguisher 1, and the sleeve 2 is clamped in the elastic card seat 11, and the sleeve 2 can be clamped and fixed by the elastic card seat 11, so as to improve the mobility of the fire extinguisher 1, a slide groove is provided on the right side of the sleeve 2, and the slide groove is connected with the inside of the sleeve 2, and an adjustment component is placed in the slide groove The adjusting assembly includes an adjusting plate 24, a pressing plate 25 is fixedly arranged on the right side of the adjusting plate 24, a group of hollow columns 21 are placed on the upper and lower sides of the adjusting plate 24, a connecting column 22 is slidably arranged inside the hollow column 21, and the pressing plate 25 can be assisted to move stably through the hollow column 21 and the connecting column 22, the right side of the connecting column 22 is connected to the left side of the pressing plate 25, and the outer rings of the hollow column 21 and the connecting column 22 are provided with springs 23, the adjusting plate 24 is inserted into the slide groove, and a sealing ring 27 is fixedly arranged in the slide groove, and the inner side wall of the sealing ring 27 is in contact with the outer side wall of the adjusting plate 24, and the sealing ring 27 can be used to In order to seal the connection gap between the slide groove and the adjustment plate 24, the pressure plate 25 is located on the right side of the sleeve 2, and the anti-skid pad 26 is evenly fixed on the right side of the pressure plate 25. The left side of the adjustment plate 24 passes through the slide groove and is located inside the sleeve 2. The left side of the adjustment plate 24 is designed as a lower left slope. The user uses the fire extinguisher 1 with his left hand, holds the sleeve 2 with his right hand, and places the thumb of his right hand on the pressure plate 25. The anti-skid pad 26 improves the comfort of pressing the pressure plate 25. When the pressure plate 25 is pressed down, it drives the adjustment plate 24 to move along the slide groove into the sleeve 2, thereby changing the size of the nozzle of the sleeve 2. Therefore, when the fire extinguisher in the fire extinguisher 1 When the agent is input into the sleeve 2 along the nozzle of the fire extinguisher 1, the effect of adjusting the spraying area is achieved by changing the size of the nozzle of the sleeve 2. Since the part of the adjusting plate 24 located inside the sleeve 2 is designed as an inclined surface, the fire extinguishing agent entering the sleeve 2 can avoid the adjusting plate 24 and be sprayed out from the sleeve 2 more smoothly. When the pressing plate 25 is released, the rebound force of the spring 23 will drive the adjusting plate 24 to reset through the pressing plate 25. Two groups of mounting holes are evenly opened on the right side of the sleeve 2. The left side of the hollow column 21 is fixedly arranged in the mounting hole, and the spring 23 is fixedly arranged between the sleeve 2 and the pressing plate 25.

[0022] Working principle: The user uses the fire extinguisher 1 with his left hand, holds the sleeve 2 with his right hand, and places the thumb of his right hand on the pressure plate 25. The four corners of the outer wall of the sleeve 2 are all chamfered, and the left side of the sleeve 2 is evenly provided with gripping grooves, so as to improve the grip comfort of the sleeve 2. The anti-slip pad 26 is used to improve the pressing comfort of the pressure plate 25. When the pressure plate 25 is pressed down, it drives the adjustment plate 24 to move along the slide groove into the sleeve 2, so as to change the nozzle size of the sleeve 2. Therefore, when the fire extinguishing agent in the fire extinguisher 1 flows along the fire extinguisher 1, the fire extinguishing agent in the fire extinguisher 1 is discharged. When the nozzle is input into the sleeve 2, the spraying area is adjusted by changing the nozzle size of the sleeve 2. Since the portion of the adjusting plate 24 located inside the sleeve 2 is designed as an inclined surface, the fire extinguishing agent entering the sleeve 2 can avoid the adjusting plate 24 and be sprayed out from the sleeve 2 more smoothly. When the pressing plate 25 is released, the rebound force of the spring 23 will drive the adjusting plate 24 to reset through the pressing plate 25. The sleeve 2 can be clamped and fixed by the elastic clamping seat 11, thereby improving the mobility of the fire extinguisher 1.
