However, this type of nozzle generally uses a water receiving tray, and the water outlet of the nozzle is aimed at the water spray tray. The fluid used for fire extinguishing is splashed around the water receiving tray, but this splashing form cannot fully diffuse the water. , it does not have an atomization effect, and the fire extinguishing efficiency is low, which often leads to the spread of fire, causing irreparable economic losses and accidents. In addition, due to the low fire extinguishing efficiency, it is necessary to extend the spraying time, resulting in a waste of fire extinguishing resources; and it is often impossible to directly start a certain sprinkler alone to implement precise fire extinguishing. Usually, sprinklers are started to spray in the fire area, which easily leads to the inability to concentrate and spray limited fire extinguishing agents onto the fire source to quickly extinguish the fire. In view of this, the present application proposes a fire extinguishing sprinkler with an atomization effect, which can improve the fire extinguishing efficiency and can be accurately released through control, which has become an urgent problem to be solved.

[0019] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.
[0020] The utility model relates to an electric heat-start atomizing nozzle, which comprises an atomizing part 1 and a heat-start nozzle mechanism 2. The atomizing part 1 has an atomizing chamber 11 inside, and opposite ends are respectively provided with a liquid inlet 12 and a liquid outlet 13 connected to the atomizing chamber 11, forming the atomizing part 1 of a tubular structure, and the heat-start nozzle mechanism 2 comprises a nozzle seat 21, an electric heat-start component 22, a plug 23 and a support frame 24, and the nozzle seat 21 has a through fluid channel 25, and the nozzle seat 21 and the atomizing part 1 are fixedly connected at the liquid outlet 13, and the fluid channel 2 One end is connected with the liquid outlet 13, and the other end forms a fluid outlet 27. The plug 23 is arranged at the fluid outlet 27 and can block the fluid outlet 27. The support frame 24 is fixed to the nozzle seat 21 and has a top seat 26 arranged toward the plug 23. There is a gap between the top seat 26 and the plug 23, and the gap is hollowed out to form a gap for the fluid to be sprayed into the atmosphere. The electric thermal starting component 22 is arranged at the gap and abuts against the top seat 26 and the plug 23 respectively, forming a support structure that resists the plug 23 from falling off and approaching the top seat 26. When the fluid passes through the atomizing chamber 11 of the atomizing part 1, a space is provided for the fluid to collide here to produce an atomization effect. The fluid in the chamber or the fluid in the atomized state flows out from the liquid outlet 13, then enters the nozzle seat 21, flows through the fluid channel 25 inside the nozzle seat 21, and then is sprayed out from the fluid spray port 27. The aperture of the fluid channel 25 is smaller than the diameter of the cavity of the atomizing chamber 11. When in use, it can have a greater pressure when the fluid spray port 27 is sprayed. The fluid flow path from the liquid inlet 12 to the fluid spray port 27 constitutes the spray pipe of the nozzle. In the unactivated state, the plug 23 blocks the fluid spray port 27 and closes the spray passage of the nozzle, but the plug 23 and the fluid spray port 27 are not connected. The outlet 27 can slide between them, and the plug 23 will be sprayed out under the pressure of the fluid. A support frame 24 is set at the bottom of the nozzle seat 21, and the support frame is fixed. In order to support the plug 23 and prevent it from detaching in the non-starting state, the plug 23 uses an electric thermal starting component 22 to support both ends between the plug 23 and the support frame 24. When it needs to be started, the electric thermal starting component 22 will start to detach from the abutting support. The plug 23 does not have the electric thermal starting component 22 as a support to support it, and is washed away by the fluid pressure in the nozzle. Then the fluid in the nozzle is sprayed out from the fluid spray port 27; specifically, the atomizing nozzle of the present application is used as a fire-fighting equipment to spray fire-extinguishing liquid, mainly water.
[0021] In order to ensure the airtight sealing effect at the fluid outlet 27 after the plug 23 is abutted, the plug 23 is a columnar structure that can extend into the fluid outlet 27, and one end is provided with a ridge 231 along the axial direction of the column, and the diameter of the ridge 231 is larger than the caliber of the fluid outlet 27, forming a clamping ring structure that allows the plug 23 to clamp the edge of the fluid outlet 27, and a positioning groove 232 is provided on the plug 23 at the position abutting against the electric thermal starting component 22, and the positioning groove 232 can accommodate the abutting end of the electric thermal starting component 22. The cylindrical structure can be used to easily match the plug 23 to the position of the fluid outlet 27 to avoid the problem of leakage caused by the plug 23 being misplaced when placed. The ridge 231 can clamp the edge of the fluid outlet 27, and the edge of the ridge 231 in contact with the fluid outlet 27 is used to achieve a tight contact between the two through the abutment force, thereby achieving a sealing and leak-proof effect. The positioning groove 232 can provide a stable abutment for the electric starting component 22 to prevent sliding, thereby improving the stability of the abutment of the plug.
[0022] In order to further improve the sealing effect of the plug 23 during plugging, a groove 233 is provided along the entire length of the convex ridge 231 at the contact surface where the convex ridge 231 and the fluid outlet 27 are locked, and a sealing ring 234 is provided in the groove 233, and the sealing ring 234 contacts and seals with the edge of the fluid outlet 27. After the sealing ring 234 is inserted into the groove 233, it is also necessary to ensure that a portion of it is higher than the groove 233, and the sealing ring 234 contacts the edge surface of the fluid outlet 27, and the sealing ring 234 is pressed to achieve the sealing effect through the contact force of the electric thermal start component 22 on the plug 23; specifically, the sealing ring 234 is an "O"-shaped sealing ring, made of nitrile rubber, with good sealing effect and a wide range of applications.
[0023] The electric starting assembly 22 includes a temperature-sensitive glass ball 221 and a heating wire 222 connected to a power source. The temperature-sensitive glass ball 221 is respectively in contact with the top seat 26 and the plug 23. The heating wire 222 is installed on the periphery of the temperature-sensitive glass ball 221 to form a heating element for the temperature-sensitive glass ball 221. When used as a starting device, the heating wire 222 is energized to heat the heating wire until the temperature at which the temperature-sensitive glass ball breaks is reached. The temperature-sensitive glass ball 221 is broken. After the breaking, there is no longer a supporting structure in contact with the plug 23 and the top seat 26. The plug 23 will be ejected by the fluid pressure inside the nozzle, thereby realizing the starting function of the nozzle. Specifically, the temperature-sensitive glass ball 221 is a capsule-shaped structure that can stably The heating wire is fixedly pressed against the positioning groove 232 and the top seat 26, but the smooth curved surfaces at both ends of the structure will not affect the smoothness of the temperature-sensitive glass ball falling off after breaking, ensuring that the nozzle will not block the plug 23 when in use; the surface of the heating wire is covered with a high-strength anti-corrosion insulation and wear-resistant coating to enhance the corrosion resistance and insulation performance to protect the resistance wire, extend the durability of the product, and will not fail when it needs to be started; in addition, the outer layer of the heating wire is also wrapped with a circle of high-temperature resistant insulating material, which can isolate the external heat source and avoid the situation of false start-up; the heating wire and the protective cover can be in the form of a structure that is sheathed on the outer circle of the temperature-sensitive glass ball, or in the form of a structure that is clamped on the outer circle of the temperature-sensitive glass ball 35 to meet different usage requirements
[0024] The atomizing nozzle of the present application can adopt three starting modes: automatic start at constant temperature by a temperature-sensitive glass ball, electrical automatic start by energizing the heating wire, and manual start. This enables the nozzle to have the functions of rapid and reliable start-up and fixed-point start-up for fire extinguishing. In the event of a fire, it can realize fixed-point start-up of the nozzles above and near the fire source to concentrate on spraying the fire extinguishing agent.
[0025] It also includes an adjusting screw 3, a threaded hole 241 is provided on the support frame 24, the adjusting screw 3 is installed in the threaded hole 241, and the top seat 26 is provided at the end of the adjusting screw 3, forming an adjusting mechanism that can adjust the interval between the top seat 26 and the plug 23 by tightening the adjusting screw 3. By setting the adjusting screw 3, after the temperature-sensitive glass ball 221 is placed in the abutting position, by tightening the adjusting screw 3, the abutting force of the temperature-sensitive glass ball 221 on the plug 23 can be increased, and the sealing ring can be pressed tightly to ensure the sealing effect.
[0026] In order to further improve the atomization effect of the nozzle on the fluid, it also includes a swirl core 4, which is installed in the atomization chamber 11 and close to one end of the liquid inlet 12. The swirl core 4 has at least two flow channels, and the flow channel outlets are arranged in relative directions to form a drainage structure that can cause the fluid to collide after passing through. Specifically, the swirl core 4 is installed at the upper part of the atomizing chamber 11 near the liquid inlet 12. When the fluid flows into the atomizing chamber 11 from the liquid inlet 12, the fluid is released before the swirl core 4. The flow channel on the swirl core 4 divides the fluid into two or more streams. The shape of the atomizing chamber 11 is a circular tube. The fluid is in the flow channel of the swirl core 4. First, the flow channel is spirally arranged. In addition, with the arc-shaped inner wall of the atomizing chamber, the fluid will be centrifugally accelerated when flowing through the flow channel. After the drainage of the flow channel, the diverted fluid finally meets at the outlet of the swirl core 4 and collides. After the collision, the fluid is broken into fine mist and then reaches the fluid outlet to be sprayed out. This can improve the atomization effect of the nozzle, improve the water mist state, and improve the atomization effect of the nozzle when spraying.
[0027] The atomizing chamber 11 includes a drainage section 111 and an atomizing section 112. The diameter of the drainage section 111 is smaller than the diameter of the atomizing section 112, forming an atomizing chamber 11 with a stepped spatial structure. The swirl core 4 is installed in the drainage section 111, and the flow channel outlet end of the swirl core 4 is arranged toward the atomizing section 112. Dividing the atomizing chamber 11 into two coarse and fine sections can further enhance the atomization effect. Specifically, when in use, when the fluid flows through the thinner drainage section 111, it is affected by the pipe diameter and the initial pressure. Entering the thinner pipe can increase the fluid pressure and speed up its passing speed. With the structure of the swirl core 4, the flow velocity of the fluid when passing through the flow channel can be further enhanced, the speed of the fluid when colliding can be increased, and the atomization effect can be increased. The atomizing section 112 in the lower section can provide sufficient space for the collision of the fluid, reduce the space to limit the collision of the water flow, and in addition, the larger space of the atomizing section 112 can be completed for the collision. The atomized fluid can be further collided and broken in the atomizing section 112, so that the atomization effect of the fluid is the best.
[0028] The flow channel of the swirl core 4 is provided with a slot 41 facing the adjacent flow channel, and the adjacent slots 41 are staggered to form a fluid passage opening for diverting toward the adjacent flow channel. While the two spiral flow channels cause the fluid to collide, the slots 41 can divert the fluid diverted into the flow channel again. The slots 41 have a small diameter so that it will not affect the fluid flow in the flow channel too much and can maintain the ejected flow rate. On this basis, the diverted fluid ejected from the slots 41 is directed toward the ejection position of the adjacent flow channel, and the fluid ejected from the slots 41 position will also collide with the fluid in the adjacent flow channel, increasing the number of fluid collision points, improving the atomization effect, and increasing the contact area between the fire extinguishing liquid and the outside world when it is ejected, thereby improving the fire extinguishing efficiency and ensuring property safety.
