[0002] A fire extinguisher is a device used to extinguish initial fires. It typically contains extinguishing agents such as dry powder, foam, carbon dioxide, or water. An adjustable fire extinguisher nozzle is a type of fire extinguisher nozzle with a flexible design that allows users to adjust the shape and flow of the spray according to the type of fire and the specific circumstances.

[0003] A search revealed Chinese Patent Publication No. CN220714663U, which discloses an adjustable fire extinguisher nozzle, belonging to the field of fire extinguisher equipment. The adjustable fire extinguisher nozzle includes a spray nozzle and a connecting pipe at one end of the spray nozzle. A rigid pipe is installed at the end of the connecting pipe away from the spray nozzle, and a locking mechanism is provided on the outside of the rigid pipe. A coaxial flared mouth is installed at the end of the rigid pipe away from the connecting pipe. The opening direction of the flared mouth is opposite to the rigid pipe, and multiple alloy plates are arranged in a circumferential array on its outer side. Sliding grooves are formed on both sides of the alloy plates, and an arc-shaped plate is placed between two opposing sliding grooves. A pull rod is installed on the outer side of each arc-shaped plate, with one end of each pull rod facing the rigid pipe and a steel ring installed between them. The locking mechanism includes multiple sets of protrusions arranged in a circumferential array on the outside of the rigid pipe. This mechanism allows for adjustment of the extinguishing agent spraying area of ​​the nozzle, and after adjustment, it can be locked, freeing up one hand to twist the nozzle to change its orientation.

[0004] The aforementioned device, while capable of limiting the adjusted flare size through the interplay between the locking mechanism and the support block, suffers from challenges due to the small size of both the protrusion and the support block. This adjustment and alignment is time-consuming and difficult. Fires are typically urgent events, and non-professionals often experience stress, further complicating the adjustment and fixing process and wasting valuable firefighting time. Therefore, an adjustable fire extinguisher nozzle is proposed to address these issues. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 2This utility model provides an embodiment of an adjustable fire extinguisher nozzle, including a hose 1 for connecting to a fire extinguisher. A nozzle 2 is fixedly connected to the front end of the hose 1. The nozzle 2 is made of a soft, stretchable, and deformable material, such as rubber. A connecting pipe 3 is fixedly connected to the front of the outer wall of the hose 1 for connecting the hose 1 to other components. The front of the outer wall of the connecting pipe 3 is provided with a spiral pattern 31 for connecting to the control ring 53 of the control component 5. A control mechanism is provided at the front of the connecting pipe 3 for controlling the size of the nozzle 2 to change the spray range of the fire extinguisher. The control mechanism includes a control component 5 and a control frame 4. A grip 6, which may be made of rubber, is fixedly connected to the rear of the outer wall of the connecting pipe 3 for anti-slip purposes. A grip groove 61 is provided on the upper part of the grip 6 to adapt to the user's gripping posture. The outer surface of the grip 6 is provided with multiple raised patterns 62 for anti-slip purposes.

[0033] like Figure 3 - Figure 5 As shown, the control assembly 5 includes a control sleeve 51, which is bucket-shaped. The distance between the control sleeve 51 and the support rod 41 increases towards the front. A connecting ring 52 is fixedly connected to the rear of the control sleeve 51, which is used to connect various components. Its inner wall does not contact the spiral pattern 31. A control ring 53 is rotatably connected to the rear side of the connecting ring 52, which is used to connect to the connecting pipe 3 and to adjust the position of the control sleeve 51 to control the opening and closing of multiple support rods 41. The control ring 53 is threadedly connected to the connecting pipe 3. A connecting groove 511 is provided on the inner wall of the control sleeve 51, which is used to connect the connecting piece 42.

[0034] Furthermore, the control frame 4 includes multiple support rods 41, which provide support for the nozzle 2 and cooperate with the opening and closing of the nozzle 2 to adjust the spray range of the nozzle 2. Multiple support rods 41 are fixedly connected to the outer wall of the nozzle 2. The rear end of the support rod 41 is movably connected to the front end of the connecting pipe 3 to cooperate with the opening and closing of the support rod 41. A connector 42 is provided between the support rod 41 and the control sleeve 51 to cooperate with the connection between the support rod 41 and the control sleeve 51. The connector 42 includes a connecting rod 421. Both ends of the connecting rod 421 are fixedly connected to connecting balls 422 to cooperate with the connection between the support rod 41 and the control sleeve 51. The connecting ball 422 on the side closer to the support rod 41 is rotatably connected to the support rod 41 and cannot be separated from the support rod 41. The connecting ball 422 on the side closer to the control sleeve 51 is slidably connected to the connecting groove 511 and cannot be detached from the connecting groove 511.

[0035] Working principle: When in use, the user presses the switch of the fire extinguisher, and the extinguishing agent in the fire extinguisher will be delivered to the nozzle 2 through the hose 1. The user can control the spray direction and angle by holding the fire extinguisher with one hand and the grip sleeve 6 with the other hand. When it is necessary to adjust the spray size of the nozzle 2, rotate the control ring 53 to move it forward or backward along the spiral pattern 31 on the connecting pipe 3. The connecting ring 52 connected to the control ring 53 will be moved accordingly, thereby moving the control sleeve 51 fixed to the connecting ring 52. When the position of the control sleeve 51 moves, the connecting ball 4 connected to the connecting groove 511 on the inner side of the control sleeve 51 will... 22 will slide within the connecting groove 511. Simultaneously, since the distance between the control sleeve 51 and the support rod 41 increases as it moves forward, when the control sleeve 51 moves backward along the connecting pipe 3, the control sleeve 51 will drive multiple support rods 41 to open outward through the connecting piece 42, thereby expanding the nozzle 2 and increasing its spray range. If it is necessary to reduce the spray range of the nozzle 2, simply rotate the control ring 53 in the opposite direction, causing it to drive the control sleeve 51 forward through the connecting ring 52, so that the control frame 4 retracts into the control sleeve 51. At this time, multiple support rods 41 will control the nozzle 2 to retract, thereby reducing the spray range of the nozzle 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
