[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, a fire sprinkler head with a large spraying area includes a sprinkler barrel 1, a sprinkler pipe 27 is arranged at the bottom of the sprinkler barrel 1, a plurality of connecting pipes 13 arranged in a circumferential array are arranged on the sprinkler pipe 27, a circular ring 31 is arranged on the sprinkler pipe 27, the circular ring 31 is rotatably arranged in the sprinkler barrel 1, a plurality of inner arc portions 23 arranged in a circumferential array are arranged on the circular ring 31, and an outer arc portion 22 is arranged on the inner arc portion 23;

[0022] When the water flow impacts the outer arc portion 22 , the push ring 31 rotates in the spray barrel 1 .

[0023] Specifically, when water pushes against the ring 31, it pushes the inner arc portion 23 on the ring 31, pushing the ring 31 to rotate on the spray tube 1. While rotating, after the water contacts the inner arc portion 23, it is guided by the shape of the inner arc portion 23 and contacts the outer arc portion 22, pushing the ring 31 to rotate in the spray tube 1, thereby increasing the spraying area.

[0024] In the above scheme, fire extinguishing is achieved through the spray barrel 1 and the spray head 14. Through the ring 31 on the connecting pipe 13, multiple connecting pipes 13 are rotated in the spray barrel to increase the spraying area. The water contacts the inner arc portion 23 and the outer arc portion 22 to push the ring 31 to rotate on the spray barrel 1.

[0025] As an embodiment further provided by the present invention, according to Figure 2 , Figure 3 and Figure 4 As shown, a chute 15 is provided in the spray barrel 1 , and an extension plate 21 is provided on the ring 31 , and the extension plate 21 is rotatably disposed in the chute 15 .

[0026] Furthermore, a plurality of elastic members 16 arranged in a circumferential array are disposed in the slide groove 15 , and a partition plate 17 is disposed on the plurality of elastic members 16 .

[0027] Furthermore, a partition plate 17 is included, and a guide slide block 24 is provided at the bottom of the extension plate 21 . The guide slide block 24 slides in the slide groove 15 and contacts the partition plate 17 .

[0028] Furthermore, a spray head 14 is provided at the bottom of the connecting pipe 13 .

[0029] Specifically, when the ring 31 is pushed and slid by water, it will be driven to slide downward and slide to the bottom of the slide groove 15. At this time, the extension plate 21 will push on the partition 17 and drive the elastic member 16 to compress. It should be noted that the water pressure during firefighting is unstable, so when the water pressure decreases, the ring 31 will be driven to move upward by the elastic member 16, so that the ring 31 can move up and down while rotating.

[0030] Working principle: when water pushes against the ring 31, it will push the inner arc portion 23 on the ring 31, push the ring 31, and make the ring 31 rotate on the spray barrel 1. While rotating, after the water contacts the inner arc portion 23, it is guided by the shape of the inner arc portion 23 and contacts the outer arc portion 22, and pushes the ring 31 to rotate in the spray barrel 1, thereby increasing the spraying area. At the same time, when the ring 31 is pushed and slides by water, it will drive the ring 31 to slide downward and slide to the bottom of the slide groove 15. At this time, the extension plate 21 will push against the partition 17 and drive the elastic member 16 to compress. It should be noted that the water pressure during fire fighting is unstable, so when the water pressure decreases, the ring 31 will be driven to move upward by the elastic member 16, so that the ring 31 can move up and down while rotating.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
