[ detailed description ] embodiments

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 2, the present invention provides an indoor spray nozzle, comprising: the device comprises a nozzle body 10, a glass tube 14, a splash plate 13 and a connecting frame 11; the outer wall of one end of the spray head body 10 is provided with an external thread, the interior of the spray head body 10 is hollow, one end of the connecting frame 11 is connected with the spray head body 10, a rotating groove 12 is formed between the other end of the connecting frame and the other end of the connecting frame, the rotating groove 12 and one end, far away from the external thread, of the spray head body 10 are arranged at intervals, the splash disc 13 is rotatably arranged on the rotating groove 12, a baffle plate 15 is further arranged on the connecting frame 11, and the baffle plate 15 is located above the splash disc 13.

Further, the nozzle body 10 is hollow in a column shape, one end of the nozzle body is a water inlet end 101, the other end of the nozzle body is a water outlet end 102, the outer wall of the water inlet end 101 is provided with external threads for connecting with a water pipe, the outer wall of the water outlet end 102 is respectively welded with one end of a pair of connecting frames 11, the pair of connecting frames 11 are oppositely arranged, the other ends of the pair of connecting frames 11 are bent towards the direction approaching to each other and are connected together by arranging a rotating groove 12 in the middle, one side of the rotating groove 12 is opened to be in a hollow cylinder shape, the inner wall of the rotating groove 12 is provided with a circle of arc-shaped grooves 121, the rotating groove 12 is positioned under the water outlet end 102 of the nozzle body 10, a splash plate 13 is rotatably arranged on the rotating groove 12 and can rotate relative to the rotating groove 12, a glass tube 14 is arranged between the splash plate 13 and the water outlet end 102, the interior of the glass tube 14 is provided with heat sensitive liquid, and when the external temperature reaches a preset value, thereby breaking the glass tube 14, wherein the water outlet end 102 of the spray head is provided with a sealing ring (not shown) which is pressed by the glass tube 14 into the water outlet end 102 for closing the water outlet end 102; in order to prevent excessive water from being sprayed on the suspended ceiling, a circle of baffle 15 is arranged in the middle of the connecting frame 11, the baffle 15 is positioned above the water splashing disc 13, when a fire disaster happens, the indoor temperature reaches the preset value, the heat sensitive liquid in the glass tube 14 acts to break the glass tube 14, the sealing ring loses the support of the glass tube 14 and is flushed away by high-pressure water flow, the water flow is sprayed out of the spray head body 10 and impacts on a sputtering disc, thereby diffusing to the periphery, and a part of water flow can be splashed towards the direction of the suspended ceiling due to the impact, at the moment, most of the water flow in the part is blocked under the action of the baffle plate 15, and is sputtered out along the baffle 15, and the other small part is sputtered onto the suspended ceiling, so that the suspended ceiling is kept moist, the suspended ceiling is prevented from being burnt, thereby avoiding the excessive water flow from splashing to the suspended ceiling to cause water waste, resulting in low fire extinguishing efficiency and causing more property loss.

In this embodiment, the baffle 15 is in the shape of a circular truncated cone and is hollow inside.

Furthermore, in order to accelerate the speed of the water flow sputtering out, the water flow is sputtered to a farther range and the fire extinguishing radius is increased, the single plate is arranged into a round table shape, the inner part of the single plate is hollow, the hollow shape is used for preventing the water of the nozzle body 10 from being blocked by the baffle 15, the round table shape is used for enabling the baffle 15 to be inclined, and when the water flow is sputtered onto the baffle 15, the water flow is obliquely flushed out along the baffle 15 and then is diffused to a farther range.

It should be noted that the baffle 15 may be a solid body, or may be in the shape of a blade 135, and the shape of the blade 135 may enable a part of the wind water to pass through the baffle 15 and splash onto the ceiling.

In this embodiment, a plurality of blades 135 are spaced around the splash plate 13, and one surface of each blade 135 close to the nozzle body 10 is inclined toward the same direction.

Further, for promoting the diffusion scope of rivers, be equipped with on the edge of splash box 13 along splash box 13 interval evenly distributed's blade 135, enlarge splash box 13 by the area of rivers striking, when rivers striking on splash box 13, rivers are the diffusion of throwing thing form along blade 135 and go out, wherein, the one side that blade 135 is close to shower nozzle body 10 all inclines towards same direction, when rivers clash on blade 135, blade 135 produces centrifugal force by the impact of rivers and drives splash box 13 and rotate, thereby throw away partial rivers to farther region fast, the spraying range of fire control shower nozzle has been enlarged, be favorable to the large tracts of land to put out a fire.

In this embodiment, a boss 131 is disposed on a surface of the splash plate 13 close to the nozzle body 10, a circle of rolling grooves 132 is disposed on a side wall of the boss 131, balls 133 are disposed in the rolling grooves 132, and the splash plate 13 is rotatably connected to the rotary groove 12 through the balls 133.

Further, in order to facilitate the rotation of the splash plate 13, a boss 131 is provided on a surface of the splash plate 13 adjacent to the nozzle body 10, a rolling groove 132 for receiving a ball 133 is provided on a sidewall of the boss 131, the rolling groove 132 is matched with the arc-shaped groove 121, and the ball 133 is positioned during the period, when the blade 135 is impacted by the water flow, a centrifugal force is generated to drive the splash plate 13 to rotate.

In this embodiment, a conical splitter is disposed at the center of one surface of the rotary trough 12 close to the nozzle body 10.

Further, the one side center that the rotary trough 12 is close to shower nozzle body 10 is equipped with the shunt that is coniform, strikes the shunt when rivers dash out from shower nozzle body 10 on, dashes to blade 135 and spreads out along the hypotenuse of shunt, avoids the direct striking of rivers at water column center to be unable sputter away on splash box 13, leads to the diffusion distance short, and the area of putting out a fire is little.

In summary, the baffle 15 in the form of a hollow truncated cone is arranged on the connecting frame 11, so that most of water splashed towards the suspended ceiling is blocked and diffused out, the water utilization rate of the spray head is improved, the splashing range of the water is increased, the fire extinguishing area is increased, and water loss and waste are avoided.

The utility model is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the utility model is not limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
