Detailed description of the preferred embodiments

The invention is further described with reference to the following figures and specific examples.

Referring to fig. 1 and 4, a water spraying nozzle with uniform water distribution comprises a shell 1, a water spraying disc 2, a sealing seat 3 for sealing the water outlet 12, wherein the upper end of the inside of the shell 1 is provided with a water inlet 11, the lower end of the inside of the shell is provided with a water outlet 12, the water splashing disc 2 is fixedly connected with a sealing seat 3, the sealing seat 3 is of an annular structure, a heat-sensitive glass column 4 is arranged in the sealing seat 3, the edge of the shell 1 is provided with a connecting rod 5, the position of the splash pan 2 corresponding to the connecting rod 5 is provided with a guide hole 21, the lower end of the connecting rod 5 is fixed with a water distribution device 6, the water distribution device 6 comprises a shell 61, a water inlet 62 positioned on the upper surface of the shell 61, a water storage cavity 63 positioned on the upper part of the shell 61 and a flow guide hole 64 positioned on the lower part of the shell 61, the upper end of the flow guide hole 64 is communicated with the water storage cavity 63, the lower end of the flow guide hole is communicated with the lower surface of the shell 61, and the heat-sensitive glass column 4 is arranged between the water distribution device 6 and the sealing seat 3. When a fire source appears indoors, the indoor temperature is increased, the thermosensitive glass column 4 filled with working liquid can sense heat at the fastest speed, the working liquid in the thermosensitive glass column 4 expands to crush the thermosensitive glass column 4, water enters the shell 1 through the water inlet 11, and the sealing device consisting of the splash disc 2 and the sealing seat 3 in a prefabricated state falls under the driving of the rupture, the water pressure and the dead weight of the thermosensitive glass column 4, so that the water outlet 12 is opened, and water flows to the splash disc 2 to be sprayed indoors and around. Because the heat-sensitive glass column 4 is broken to cause the complete closed system to be broken, the hole in the middle of the sealing seat 3 is opened, partial water flow enters the hole, enters the water distribution device 6 through the water inlet hole 62 under pressure, is buffered and stored by the water storage cavity 63, and then is guided by the guide hole 64 to be sprayed in a covering mode to the area right below the water spraying nozzle.

As shown in fig. 2, the diameter of the water inlet 11 is larger than that of the water outlet 12. Since the coverage area of the water splash plate 2 sprayed to the indoor periphery depends on the water pressure, and the pressure of the water pipe connected with the water spray nozzle is usually small, the flow rate of water is increased by reducing the diameter of the water outlet 12 and reducing the water flux in unit time, namely, the water flow before spraying is simply pressurized.

As shown in fig. 1-2, the number of the connecting rods 5 is at least 3. Because the water distribution device 6 is added, the shell 1 can be subjected to the superposition of a plurality of forces such as self weight, the gravity of the water distribution device 6, the pressure of water flow, the gravity of water in the water storage cavity 63 and the like, so that not less than 3 connecting rods 5 are needed to draw the water distribution device 6 and evenly distribute the stress for the shell 1. So as to ensure the overall stability and the normal work of the water distribution device 6.

As shown in fig. 2, the water distribution device 6 is provided with through holes 65 corresponding to the connecting rods 5 in number and position, the bottom of the connecting rod 5 is provided with a threaded portion 51, and the threaded portion 51 passes through the through holes 65 and is locked and connected with the water distribution device 6 through a nut 52. In order to prevent the heat-sensitive glass column 4 from falling off under the influence of water pressure, the water distribution device 6 is forced by the locking nut 52 to distribute part of the heat-sensitive glass column 4, so as to avoid the falling-off condition. In order to enable the water distribution device 6 and the water splash plate 2 to function, in a working state, the falling process of the water splash plate 2 under the action of water pressure and self weight cannot be infinite, so that the water distribution device 6 is fixed and the water splash plate 2 is limited through the matching of the threaded part 51 and the nut 52. Meanwhile, in the whole working process, the water distribution device 6 is flushed by water pressure, so that parts can be damaged to a certain extent, and the detachable connection mode is favorable for replacing the parts.

Referring to fig. 2, a clamping groove 66 for fixing the temperature-sensitive glass column 4 is arranged on the upper surface of the water distribution device 6 corresponding to the position of the bottom 4 of the temperature-sensitive glass column. In order to enhance the sensitivity of the heat-sensitive glass column 4, thin glass is usually selected as the outer wall, and both ends are designed to be smooth arcs so as to facilitate the breakage of the heat-sensitive glass column, and the heat-sensitive glass column 4 is further fixed by additionally arranging a clamping groove 66 on the upper surface of the water distribution device 6 so as to prevent the heat-sensitive glass column 4 from falling off or being damaged and causing adverse effects on the overall use.

As shown in fig. 2, the upper ends of the diversion holes 64 are concentrated at the center of the lower surface of the water storage cavity 63 and extend towards the outer ring of the lower surface of the housing 61. Although the purpose of the diversion holes 64 is to divert water downward so that the working area can cover the area right below, in order to prevent only the periphery and right below from being covered and to prevent the middle from having an annular uncovered area, the diversion holes 64 are configured to extend from the center to the outer ring, thereby effectively avoiding the above disadvantages. Meanwhile, the water storage cavity 63 is matched to achieve the buffer effect on the water flow below the water storage cavity. The phenomenon that the normal coverage of the splash pan 2 to the surrounding area is influenced due to overlarge flux caused by the fact that the speed of water flow under the splash pan is too high is avoided.

As shown in fig. 2-3, a through pipe 7 penetrating the water distribution device is arranged in the center of the water distribution device 6, an atomizer 8 is embedded at the lower part of the water distribution device 6, and the atomizer 8 is communicated with the lower part of the through pipe 7. In case of fire, the temperature and smoke generated by combustion are the most harmful to human body. Through embedding atomizer 8 under water distributor 6, carry out the liquid drop atomization processing with the rivers of a small part usefulness of putting out a fire, make its can be a small amount reduce indoor temperature to effectual produced smoke and dust of burning is adsorbed and is subsided the processing through the peculiar adsorptivity of liquid droplet, reduces its injury to the human body, and the extension indoor personnel put out a fire or wait for the time of rescue.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
