[0002] In order to ensure the safety of people's lives and property, a large number of sprinkler heads are usually installed in buildings or skyscrapers to prevent fires and extinguish fires. However, these sprinkler heads basically serve as water outlets. After a fire occurs, the water outlets release water and increase the spraying area through the splash baffle at the bottom. This spraying method has low fire extinguishing efficiency, and the amount of fire extinguishing agent required for fire extinguishing is also large. When a fire occurs, the activation speed of the sprinkler head is also slow. In view of this, the present application is specially filed. Utility Model Content

[0018] The present invention will be further described below with reference to the embodiments, but is not limited to the contents of the specification.
[0019] like Figures 1 to 3As shown, the utility model relates to an electric explosion-start atomizing nozzle, which includes a nozzle body 1, an atomizing core 2, a plug 3 and an electric explosion-starting assembly 4. The nozzle body 1 has a through fluid cavity 11, and a liquid inlet 12 and a spray port 13 formed in the top and bottom directions, and a fixed bracket 14 extending in the direction of liquid spraying is provided at one end of the spray port 13. The atomizing core 2 is arranged in the fluid cavity 11, and the plug 3 is plugged in the spray port 13. The electric explosion-starting assembly 4 is located between the plug 3 and the fixed bracket 14, and abuts against the fixed bracket 14 and the plug 3 respectively to form a support structure for preventing the plug 3 from detaching from the spray port 13. The atomizing core 2 is columnar and matches the shape of the fluid cavity 11, and is provided with a plurality of diversion channels 21 passing through the two end faces. The plurality of diversion channels 21 are arranged in a circumferential shape, and the channel openings of the same diversion channel 21 at the two end faces are staggered to form a guide structure that can guide the flow direction of the fluid. When in use, the liquid inlet 12 on the nozzle body 1 is connected to the pipeline for supplying the fire extinguishing agent. The flow direction of the fire extinguishing agent is from the liquid inlet 12 to the nozzle outlet 13, and the atomization effect is completed through the atomizing core 2 on the way. Specifically, the fire extinguishing agent can only flow through the diverter channel 21 on the atomizing core 2 when passing through the passage. The aperture of the diverter channel 21 is much smaller than the diameter of the fluid cavity 11. When the pressure of the fire extinguishing agent delivery remains unchanged, the flow rate of the fire extinguishing agent in the diverter channel 21 is increased. When the fire extinguishing agent is ejected from the diverter channel 21, the faster flow rate causes the fire extinguishing agent to collide with the blocking obstacle and then scatter the fire extinguishing agent to achieve the atomization effect. The staggered arrangement of the channel openings at the two end faces of the same diverter channel 21 can make the state of the fire extinguishing agent when it is ejected not directly toward the nozzle 13, but obliquely. The obliquely ejected fire extinguishing agent fluid will collide with the inner wall of the fluid cavity 11, or the two ejected fluids on its flow path. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire. The extinguishing agent 12 is discharged from the nozzle 13 to extinguish the fire.
[0020] Multiple diversion channels 21 are located at the end faces of the atomizer core 2, arranged in a circular pattern. The circumference of the circle is concentric with the end face of the atomizer core 2, and the diversion channels 21 form an angle with the axis of the atomizer core 2. The uniform hole arrangement ensures that the liquid outlets of the diversion channels 21 spray in the same direction. Furthermore, by setting the angle with the axis, the direction of the fire extinguishing agent spray is guaranteed to be toward the inner wall of the fluid chamber 11. The fluid quickly impacts the side walls and disperses to form a fine mist, achieving an atomization effect.
[0021] The diverter channel 21 is a straight channel, extending toward the inner wall of the fluid chamber 11 and not overlapping with the extension line of the channel length of adjacent diverter channels 21. This straight channel makes it easier to determine the angle at which the fluid in the diverter channel is sprayed into the fluid chamber 11, ensuring effective atomization after the fluid impacts. The diverter channels 21 with non-overlapping extension lines ensure that the fluids ejected from adjacent channels do not affect each other, avoiding the problem of poor atomization caused by fluid collision.
[0022] The diversion channel 21 can also use an arc-shaped channel, and the convex arc of the arc-shaped channel can generate centrifugal force in the fluid when the fluid passes through it during use, provide centrifugal acceleration, and generate a faster flow rate at the moment the fluid is ejected, and impact the inner wall to produce an atomization effect.
[0023] The electric explosion starting assembly 4 includes a temperature-sensitive glass ball 41, an electric explosion starter 42, an elastic member 43 and a wire 44. The temperature-sensitive glass ball 41 is respectively in contact with the plug 3 and the fixed bracket 14. The electric explosion starter 42 is a ring-shaped structure and is sleeved on the outer periphery of the temperature-sensitive glass ball 41. The elastic member 43 is respectively connected to the electric explosion starter 42 and the fixed bracket 14, and there is elastic potential energy between the two, forming a dislocation mechanism that can bounce off the electric explosion starter 42. The wire 44 is respectively electrically connected to the electric explosion starter 42 and the power supply to form an electric starting circuit. Specifically, after the wire 44 receives the electrical signal, the electric explosion starting assembly is started. When in use, the electric explosion starter 42 receives the starting electrical signal of the wire 44, and the internal electrically started explosive will break the temperature-sensitive glass ball 41. The broken temperature-sensitive glass ball 41 no longer has the supporting ability, and then the plug 3 supported by the temperature-sensitive glass ball 41 will be opened by the internal pressure, opening the nozzle 13 to start spraying the fire extinguishing agent to extinguish the fire. The elastic member 43 is used to bounce the temperature-sensitive glass ball 41 from the supporting position after it has no supporting force, to prevent the stuck plug from escaping from the nozzle, resulting in the nozzle cannot be fully opened and the fire extinguishing agent cannot be sprayed in the most efficient fire extinguishing state, affecting the fire extinguishing effect; the wire 44 can also be connected to the controller to quickly start the electric explosion starter to extinguish the fire through human or sensor signals.
[0024] The elastic member 43 is a spring sheet, the middle section of which contacts the periphery of the electric explosive starter 42, and has elastic arms extended at both ends. The elastic arms are clamped with the fixed bracket 14 on the side opposite to the contact portion of the middle section of the spring sheet, forming a bow-shaped elastic structure with the contact position of the middle section of the spring sheet as the bending portion. Specifically, a spring piece with good elastic recovery performance is used, and the middle section is lower than the outer periphery of the electric explosive starter 42. The electric explosive starter is in a fixed position because the glass ball is pressed together, and the positions of the two sides of the spring piece are stuck with the edge of the fixed bracket 14 on the opposite side of the contact surface, so that the position in contact with the outer periphery of the electric explosive starter 42 is arc-shaped and has elastic potential energy. The elastic force is applied to the electric explosive starter 42. At this time, the state of the entire spring piece is in the shape of a bow. When the glass ball breaks, the electric explosive starter 42 does not have a force application position that can resist the elastic force of the spring piece and will be bounced away by the spring piece. In addition, the contact position between the end of the spring piece and the fixed bracket 14 is stuck. After the electric explosive starter 42 is bounced away, the spring piece itself can no longer remain in its original position and will fall off, which will not affect the falling off of the plug.
[0025] The electric explosion starter 42 includes an inner electric explosion layer 421 and an outer reinforcement layer 422. The electric explosion layer 421 is bonded to the outer surface of the temperature-sensitive glass ball 41. The reinforcement layer 422 is provided with a notch for the shrapnel to pass through. The part of the shrapnel that passes through the notch contacts the electric explosion layer 421. When in use, the glass ball is shattered by the electric explosion layer 421, while the outer reinforcement layer 422 is not affected by the electric explosion layer 421. The notch connects the shrapnel and the electric explosion starter 42 to the position where the shrapnel and the electric explosion starter 42 will be ejected together to spray the fire extinguishing agent. Specifically, the electric explosion layer 421 uses solid gunpowder, which is instantly detonated by an electric ignition head to quickly generate heat and blast the temperature-sensitive glass ball 41, making the nozzle start more quickly.
[0026] The plug 3 is provided with a circle of ridges 31 along the entire length of the circumferential direction. The ridges 31 can cover the edge of the ejection port 13, forming a cap-like structure with an edge seal at the exit of the ejection port 13. A concave retaining groove 32 capable of accommodating the abutting end of the electric explosive starting assembly 42 is provided at the abutment between the plug 3 and the electric explosive starting assembly 42, and a blind hole is provided along the concave extension direction of the retaining groove 32. The ridges 32 can increase the edge contact area at the position where the plug contacts the ejection port, and form a limit to prevent the plug from entering the ejection port 13 too deeply. The retaining groove 32 provides a stable abutment position for the glass ball to prevent sliding. The provision of the blind hole can reduce the overall quality of the plug and reduce the pressure required when the plug is removed from position.
[0027] The contact surface between the ridge 31 and the edge of the discharge port 13 is provided with a receiving groove 33. A sealing ring 34 is embedded in the receiving groove 33. The sealing ring 34 protrudes from the receiving groove 33 and contacts the edge of the discharge port 13 for sealing. The sealing ring 34 is arranged in the groove 33 and has a portion thereof protruding. The protruding portion presses against the discharge port 13 to enhance the sealing effect and prevent leakage of the fire extinguishing agent. Specifically, the sealing ring is an O-ring made of nitrile rubber, which has the characteristics of good sealing effect and wide application range.
[0028] The fixing bracket 14 is provided with a screw hole 141, and an adjusting screw 142 is threadedly connected to the screw hole 141. The end of the adjusting screw 142 faces the electric explosive starting component 42 and has a limit seat 143 for the electric explosive starting component 42 to abut. The limit seat 143 is a concave structure that can accommodate the abutment section of the electric explosive starting component 42, forming an adjustment and fastening mechanism that can adjust the interval between the limit seat 143 and the clamping groove 32 by screwing the adjusting screw 142 in the screw hole 141. By tightening the adjusting screw 142 in the screw hole 141, the electric explosive starting component 42 in the middle position can be squeezed, playing an adjustment role, and facilitating installation and clamping.
