Description
Technical Field
[0001] This utility model relates to the field of fire protection technology, specifically to an atomizing nozzle. Background Technology
[0002] Fire protection facilities refer to fixed facilities within buildings such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants. Automatic sprinkler systems are currently the most commonly used automatic fire extinguishing facilities in my country, and are installed in large numbers in buildings where public gathering places are located. Automatic sprinkler systems are highly effective in extinguishing initial fires when no one is present, greatly improving the safety performance of buildings. Ensuring the integrity and effectiveness of automatic sprinkler systems is of great significance, and the atomizing nozzles play a crucial role in these systems.
[0003] Patent publication number CN216258842U discloses an atomizing nozzle for fire-fighting fine water mist, including a nozzle middle section. The nozzle middle section includes a nozzle handle, a middle nozzle body, a nozzle baffle, a fine water mist hole, and a connecting groove. The nozzle baffle has a fine water mist hole on its outer wall. The nozzle rear section is hollow, and a connecting block is fixedly connected to the nozzle rear section at the position corresponding to the connecting groove.
[0004] To address the issue of inconvenient disassembly, existing technology uses a connecting groove and a connecting block to fix the middle and rear sections of the nozzle. When disassembly is needed, the front section of the nozzle is removed from the middle section, and then the connecting groove and connecting block are pulled apart to remove the middle section from the rear section. This allows for easy disassembly of both the middle and front sections of the nozzle, facilitating subsequent cleaning. The nozzle baffle also provides some protection against foreign objects entering the front section and affecting water flow. However, this method still results in issues such as low atomization, uneven distribution, and insufficient diffusion of the water mist, leading to poor spraying performance. Utility Model Content
[0005] The purpose of this invention is to provide an atomizing nozzle to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] An atomizing nozzle includes a thermal glass bulb, the surface of which is provided with an atomizing nozzle assembly.
[0008] The atomizing nozzle assembly includes a lower support bracket, which is fixedly installed at the bottom of the thermal glass bulb. A connecting frame is fixedly installed on the surface of the lower support bracket, and a lower fixing seat is snapped onto the surface of the connecting frame. An atomizing ring is fixedly installed inside the lower fixing seat. The bottom of the atomizing ring is provided with micro-spray holes, and multiple sets of micro-spray holes are provided. The micro-spray holes are evenly distributed at the bottom of the lower fixing seat, and the micro-spray holes are adapted to the atomizing ring.
[0009] A further improvement of the present invention is that: a nozzle housing is fixedly installed on the surface of the lower end fixing seat, and the surface of the nozzle housing is provided with housing spray holes, and multiple sets of housing spray holes are provided, and the housing spray holes are evenly distributed on the surface of the nozzle housing.
[0010] A further improvement of this utility model is that an upper connecting pipe is fixedly installed at the top of the nozzle housing, and a filter element is movably installed inside the upper connecting pipe.
[0011] A further improvement of the present invention is that the atomizing nozzle assembly further includes a barrier sleeve, which is movably installed inside the nozzle housing and fixedly installed on the surface of the connecting frame.
[0012] A further improvement of this utility model is that: the surface of the barrier sleeve is provided with connecting holes, and multiple sets of connecting holes are provided, and the connecting holes are evenly distributed on the surface of the barrier sleeve.
[0013] A further improvement of this utility model is that a blocking valve core is movably installed on the blocking sleeve, and the bottom end of the blocking valve core is fixedly installed on the top end of the thermosensitive glass bulb.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] This utility model provides an atomizing nozzle, which employs a combination of a thermal glass bulb, a lower support bracket, a connecting frame, a lower fixing seat, a nozzle housing, a housing spray hole, a micro-spray hole, an upper connecting pipe, a filter element, a sealing valve core, a barrier sleeve, a connecting hole, and an atomizing ring. By installing a filter element inside the upper connecting pipe, when water flows into the pipe, the filter element filters the water flow, preventing clogging of the nozzle. Simultaneously, the filter element can be replaced by disassembling the upper connecting pipe, reducing maintenance difficulty. The bottom end of the sealing valve core, in conjunction with the lower support bracket, clamps the thermal glass bulb. When the thermal glass bulb breaks due to heat, the water pressure generated by the water flow pushes the sealing valve core. When displaced downwards, the water flow can enter the cavity formed by the nozzle housing and the barrier sleeve. The water flow is atomized by the atomizing ring inside the lower fixed seat and then sprayed out through the tiny nozzle holes. At the same time, fifteen to seventeen housing nozzle holes are set on the surface of the nozzle housing, with two different spray angles and alternating distribution. When the housing nozzle holes come into contact with the fine water flow sprayed from the tiny nozzle holes, the high-speed impact increases the degree of atomization, making the water mist particles reach 80μm, with uniform distribution and more complete diffusion. Meanwhile, the barrier sleeve is connected to the connecting frame, so when the internal sealing valve core needs to be replaced, only the barrier sleeve needs to be disassembled, which improves the adaptability of the device.

[0021] The present invention will be further described in detail below with reference to embodiments:
[0022] Example 1
[0023] like Figure 1-4As shown, this utility model provides an atomizing nozzle, including a thermal glass bulb 1, and an atomizing nozzle assembly 2 is disposed on the surface of the thermal glass bulb 1;
[0024] The atomizing nozzle assembly 2 includes a lower support bracket 201, which is fixedly installed at the bottom of the thermal glass bulb 1. A connecting frame 202 is fixedly installed on the surface of the lower support bracket 201, and a lower fixing seat 203 is snapped onto the surface of the connecting frame 202. An atomizing ring 212 is fixedly installed inside the lower fixing seat 203. A micro-spray hole 206 is provided at the bottom of the atomizing ring 212. Multiple sets of micro-spray holes 206 are provided and are evenly distributed at the bottom of the lower fixing seat 203. The micro-spray holes 206 are adapted to the atomizing ring 212.
[0025] In an optional embodiment: a nozzle housing 204 is fixedly mounted on the surface of the lower end fixing base 203, and the surface of the nozzle housing 204 is provided with housing spray holes 205. Multiple sets of housing spray holes 205 are provided, and the housing spray holes 205 are evenly distributed on the surface of the nozzle housing 204.
[0026] It should be noted that by setting fifteen to seventeen housing spray holes 205 on the surface of the nozzle housing 204, and having two different spray angles, which are alternately distributed, the spray range is improved in conjunction with the micro spray holes 206.
[0027] In an optional embodiment: an upper connecting pipe 207 is fixedly installed on the top of the nozzle housing 204, and a filter element 208 is movably installed inside the upper connecting pipe 207.
[0028] It should be noted that by installing a filter element 208 inside the upper connecting pipe 207, the filter element 208 filters the water flow when it enters the upper connecting pipe 207, preventing the nozzle from being blocked. At the same time, the filter element 208 can be replaced by removing the upper connecting pipe 207, reducing the difficulty of maintenance.
[0029] In an optional embodiment, the atomizing nozzle assembly 2 further includes a barrier sleeve 210, which is movably installed inside the nozzle housing 204 and fixedly installed on the surface of the connecting frame 202.
[0030] It should be noted that the blocking sleeve 210 is connected to the connecting frame 202, so that when the internal sealing valve core 209 needs to be replaced, only the blocking sleeve 210 needs to be removed.
[0031] In an optional embodiment: the surface of the barrier sleeve 210 is provided with a connecting hole 211, and multiple sets of connecting holes 211 are provided, and the connecting holes 211 are evenly distributed on the surface of the barrier sleeve 210.
[0032] It should be noted that when the water pressure generated by the water flow pushes the sealing valve core 209 downward, the water flow can enter the cavity formed by the nozzle housing 204 and the blocking sleeve 210 through the connecting hole 211 to complete the water spraying.
[0033] In an optional embodiment, a blocking sleeve 210 is movably mounted with a blocking valve core 209, the bottom end of which is fixedly mounted on the top end of the thermal glass bulb 1.
[0034] It should be noted that the thermosensitive glass bulb 1 is clamped by the cooperation between the bottom end of the sealing valve core 209 and the lower support bracket 201. When the thermosensitive glass bulb 1 is damaged by heat, the sealing valve core 209 moves downward to allow water to flow.
[0035] In this embodiment, a filter element 208 is installed inside the upper connecting pipe 207. When water flows into the upper connecting pipe 207, the filter element 208 filters the water flow to prevent clogging of the nozzle. Simultaneously, the filter element 208 can be replaced by disassembling the upper connecting pipe 207, reducing maintenance difficulty. The bottom end of the sealing valve core 209 cooperates with the lower support bracket 201 to clamp the thermal glass bulb 1. When the thermal glass bulb 1 breaks due to heat, the water pressure generated by the water flow pushes the sealing valve core 209 downwards, allowing water to enter the cavity formed by the nozzle housing 204 and the blocking sleeve 210, and then flow through the lower fixing seat 2. The atomizing ring 212 inside the nozzle 203 atomizes the water and sprays it out through the micro-spray holes 206. At the same time, fifteen to seventeen housing spray holes 205 are provided on the surface of the nozzle housing 204, and they have two different spray angles and are distributed alternately. When the housing spray holes 205 come into contact with the fine water flow sprayed from the micro-spray holes 206, the high-speed impact increases the degree of atomization, making the water mist particles reach 80μm, which are evenly distributed and diffused more fully. Meanwhile, the barrier sleeve 210 is connected to the connecting frame 202, so that when the internal sealing valve core 209 needs to be replaced, only the barrier sleeve 210 needs to be removed, which improves the adaptability of the device.
[0036] The working principle of this atomizing nozzle will be explained in detail below.
[0037] like Figure 1-4As shown, by installing a filter element 208 inside the upper connecting pipe 207, when water flows into the upper connecting pipe 207, the filter element 208 filters the water flow to prevent clogging of the nozzle. Simultaneously, the filter element 208 can be replaced by disassembling the upper connecting pipe 207, reducing maintenance difficulty. The bottom end of the sealing valve core 209, in cooperation with the lower support bracket 201, clamps the thermal glass bulb 1. When the thermal glass bulb 1 breaks due to heat, the water pressure generated by the water flow pushes the sealing valve core 209 downwards, allowing water to enter the cavity formed by the nozzle housing 204 and the blocking sleeve 210, and then flow through the lower fixing seat 203. The internal atomizing ring 212 atomizes the water and sprays it out through the micro-spray holes 206. At the same time, fifteen to seventeen housing spray holes 205 are provided on the surface of the nozzle housing 204, and they have two different spray angles and are distributed alternately. When the housing spray holes 205 come into contact with the fine water flow sprayed from the micro-spray holes 206, the high-speed impact increases the degree of atomization, making the water mist particles reach 80μm, which are evenly distributed and diffused more fully. Meanwhile, the barrier sleeve 210 is connected to the connecting frame 202, so that when the internal sealing valve core 209 needs to be replaced, only the barrier sleeve 210 needs to be removed, which improves the adaptability of the device.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
