The body 1 is connected with the splash box 2 through a spray head frame 9, the sealing seat 3 is installed at the water outlet end of the body 1, and a group of starting assemblies for starting the spray head are installed on the body 1.
Referring to fig. 1-4, the starting assembly of the present invention comprises a temperature sensing element 7, a cross pressing rod 5, two fixing hooks 8 and two oblique pressing rods 4.
The temperature sensing element 7 comprises two metal sheets which are mutually lapped, the lapped parts are welded by fusible solder (the solder is 74-degree alloy solder purchased by Shanghai chart novel welding materials Co., Ltd.), and the two metal sheets are respectively provided with a first through hole 71. The two ends of each fixing hook 8 are respectively a connecting end and a fixing end, the connecting end is fixed with the body 1, and the fixing end extends between the body 1 and the splash pan and is positioned on the outer side of the edge of the splash pan 2 in the horizontal direction; the middle part of the transverse pressure rod 5 is arranged on the sealing seat, and two ends of the transverse pressure rod respectively extend to the lower part of the fixed end of the fixed hook.
Referring to fig. 5, the miter bar includes an upper bent portion 41, a straight rod portion 42, and a lower bent portion 43, an included angle between the upper bent portion 41 and the straight rod portion 42 is an obtuse angle, an included angle between the lower bent portion 43 and the straight rod portion 42 is an acute angle, and specifically, the upper bent portion 41 and the lower bent portion 43 are both inclined to the outside. The upper bending part 41 passes through the first through hole 71 of the metal sheet, meanwhile, the metal sheet applies a pulling force to the inclined pressing rod towards the center direction, the joint of the lower bending part 43 and the straight rod part 42 is abutted against the upper surface of the end part of the transverse pressing rod 5, and the tail end of the lower bending part 43 extends to the lower part of the fixed end of the fixed hook 8.
Preferably, in this embodiment, the free end of the lower bent portion 43 is provided with a short top sheet 44 forming an acute angle with the lower bent portion, and the short top sheet 44 extends below the fixed end.
The fixed end of the fixed hook 8 is provided with a second through hole (not shown in the figure), the second through hole is internally provided with an adjusting screw 6, and the bottom of the adjusting screw 6 penetrates through the second through hole to abut against the short top plate 44.

The working principle of the invention is as follows:
when a fire disaster happens, the temperature sensing element arranged on the outermost side of the top of the spray head is heated under the action of radiant heat, when the temperature is raised to a certain temperature, the solder between the metal sheets is melted, the two metal sheets are separated, the upper parts of the 2 inclined pressing rods 4 are not restrained, the upper parts of the 2 inclined pressing rods 4 move towards the direction far away from each other, the lower parts of the inclined pressing rods 4 are separated from the adjusting screws 6, and the acting force of the inclined pressing rods 4 on the transverse pressing rods 5 disappears. Therefore, the pressure of the transverse compression rod 5 on the sealing seat 3 disappears, and finally, the sealing seat 3 is pushed open by water pressure to extinguish fire.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
