Description

Technical Field

[0001] This utility model belongs to the field of atomizing nozzle technology, specifically a special atomizing nozzle for fire extinguishing devices in kitchen equipment. Background Technology

[0002] Kitchen fires, especially oil fires and electrical fires, have become one of the most common and dangerous types of fires in home and commercial kitchens. With the increasing number of kitchen cooking equipment, the risk of kitchen fires is also increasing.

[0003] Automatic kitchen fire suppression systems, especially automatic sprinkler systems, have been increasingly used in kitchen fire suppression in recent years. Most existing kitchen equipment fire extinguishing nozzles use a single spray method, which has some significant shortcomings. Existing nozzles generally rely on fixed spray patterns, such as simple direct spray. For kitchen fires, this single spray method often cannot fully cover the entire fire source, resulting in unsatisfactory fire suppression effects. Therefore, we propose a special atomizing nozzle for kitchen equipment fire suppression devices. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a special atomizing nozzle for a fire extinguishing device in kitchen equipment, comprising a fire pipe, a nozzle body being provided at the head of the fire pipe, a fireproof solenoid valve being provided between the nozzle body and the fire pipe, the fireproof solenoid valve having a temperature sensor inside, requiring an external power supply during installation, the fireproof solenoid valve being normally closed during operation, and only opening when the temperature sensor detects that the temperature exceeds a set value, a connecting ring being provided on the nozzle body, multiple bottom nozzles being provided on the connecting ring, a spiral plate being provided on the nozzle body, the spiral plate spiraling around the nozzle body circumferentially, multiple spiral nozzles being evenly arranged on the spiral plate, and multiple through channels being provided inside the nozzle body, the multiple through channels communicating with the bottom nozzles and the spiral nozzles.

[0005] Preferably, the nozzle body has a circular cross-section, which allows for even distribution of water flow. Multiple bottom nozzles are arranged in a ring at the bottom of the nozzle body, with the nozzles facing downwards, to ensure that the water mist evenly covers the fire source and avoids local stagnation.

[0006] Preferably, the multiple spiral nozzles are oriented in all directions along the spiral plate trajectory, allowing the water mist to spread outwards along the spiral plate trajectory, maximizing the use of water flow to cover a wider area. The distribution of the spiral nozzles ensures uniform spray angle and avoids overly concentrated spraying.

[0007] Preferably, both the bottom nozzle and the spiral nozzle are atomizing nozzles, and both the bottom nozzle and the spiral nozzle are provided with a vortex-shaped guide plate. The vortex-shaped guide plate is composed of multiple trapezoidal plates arranged to form a vortex shape. The atomizing nozzle can spray water into fine water mist, increasing the surface area of ​​the water and thus improving the fire extinguishing efficiency. The guide plate can guide the water flow to form a vortex effect, making the water flow more evenly distributed, and thus more effectively atomizing the water flow and improving the fire extinguishing effect.

[0008] Preferably, the surfaces of the bottom nozzle, spiral nozzle, and vortex-shaped guide plate are all coated with a Teflon coating. Teflon is a material with good high temperature resistance, corrosion resistance, and anti-adhesion properties, which can prevent the adhesion of pollutants such as grease and fumes and reduce the risk of nozzle clogging.

[0009] Preferably, the spacing between the spiral nozzles on the spiral plate is 10-15mm, which helps to maintain a reasonable distance between the nozzles, so that the water flow can be evenly distributed and will not form a phenomenon of excessively dense or sparse water flow.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] When a kitchen fire occurs, the fireproof solenoid valve responds to the high-temperature changes of the fire. If the temperature exceeds the set value, the fireproof solenoid valve will automatically activate, and water will enter the sprinkler head through the fire hose. It will then be distributed to the bottom nozzle and spiral nozzle through multiple through channels. When the water flows through the bottom nozzle, the water mist is sprayed downwards in a ring pattern. The spiral nozzle diffuses the water mist in all directions along the path of the spiral plate. The vortex-shaped guide plates inside the nozzle form a vortex flow through a trapezoidal arrangement, which helps the water flow to form a strong rotating motion, further atomizing the water flow and making the water molecules as fine as possible. By spraying water mist through atomization, the water avoids direct contact with the fire source. Especially in oil fires and electrical fires, this reduces the risk of secondary disasters such as oil explosions or electrical short circuits. The water mist quickly absorbs heat and lowers the temperature of the fire source, achieving the effect of quickly extinguishing the fire. It can quickly form a uniform water mist coverage layer when a fire occurs, widely covering the entire fire source area. Compared with traditional water sprinkler fire extinguishing devices, water mist is easier to penetrate and distribute evenly, and can quickly extinguish fires. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figure 1-4 The present invention includes a fire-fighting pipe 1, a nozzle body 2 at the head of the fire-fighting pipe 1, a fireproof solenoid valve 7 between the nozzle body 2 and the fire-fighting pipe 1, the fireproof solenoid valve 7 having a temperature sensor inside, requiring an external power supply during installation, the fireproof solenoid valve 7 being normally closed during operation, and only opening when the temperature sensor detects that the temperature exceeds a set value, the nozzle body 2 having a connecting ring 3, multiple bottom nozzles 4 on the connecting ring 3, a spiral plate 5 on the nozzle body 2, the spiral plate 5 spiraling around the nozzle body 2, multiple spiral nozzles 9 evenly arranged on the spiral plate 5, and multiple through channels 6 inside the nozzle body 2, the multiple through channels 6 communicating with the bottom nozzles 4 and the spiral nozzles 9.

[0020] The nozzle body 2 has a circular cross-section, which allows for even distribution of water flow. Multiple bottom nozzles 4 are arranged in a ring at the bottom of the nozzle body 2, with the nozzles facing downwards to ensure that the water mist evenly covers the fire source and avoids local stagnation.

[0021] Multiple spiral nozzles 9 are arranged along the trajectory of the spiral plate 5, allowing the water mist to spread outwards along the trajectory of the spiral plate 5, maximizing the use of water flow to cover a wider area. The distribution of the spiral nozzles 9 ensures uniform spray angle and avoids overly concentrated spraying.

[0022] Both the bottom nozzle 4 and the spiral nozzle 9 are atomizing nozzles. Both the bottom nozzle 4 and the spiral nozzle 9 are equipped with a vortex-type guide plate 8. The vortex-type guide plate 8 is composed of multiple trapezoidal plates arranged to form a vortex shape. The atomizing nozzle can spray water into fine water mist, increasing the surface area of ​​the water and thus improving the fire extinguishing efficiency. The guide plate can guide the water flow to form a vortex effect, making the water flow more evenly distributed, and thus more effectively atomizing the water flow and improving the fire extinguishing effect.

[0023] The surfaces of the bottom nozzle 4, spiral nozzle 9, and vortex-type guide plate 8 are all coated with Teflon. Teflon is a material with good high temperature resistance, corrosion resistance, and anti-adhesion properties, which can prevent the adhesion of pollutants such as grease and fumes and reduce the risk of nozzle clogging.

[0024] The spiral nozzles 9 on the spiral plate 5 are spaced 10-15mm apart, which helps to maintain a reasonable distance between the nozzles, so that the water flow can be evenly distributed and will not form a phenomenon of excessively dense or sparse water flow.

[0025] Working principle: When a kitchen fire occurs, the fireproof solenoid valve 7 responds to the high temperature changes of the fire. When the temperature exceeds the set value, the fireproof solenoid valve 7 will automatically activate. Water enters the nozzle body 2 through the fire pipe 1 and is distributed to the bottom nozzle 4 and spiral nozzle 9 through multiple through channels 6. When the water flows through the bottom nozzle 4, the water mist is sprayed downward in a ring pattern. The spiral nozzle 9 diffuses the water mist in all directions along the path of the spiral plate 5. The vortex-shaped guide plates 8 inside the nozzle form a vortex flow through a trapezoidal arrangement, which helps the water flow to form a strong rotating motion, further atomizing the water flow and making the water molecules as fine as possible. By spraying water mist in an atomized manner, the water avoids direct contact with the fire source. Especially in oil fires and electrical fires, it reduces the risk of secondary disasters such as oil fire explosions or electrical short circuits. The water mist quickly absorbs heat and lowers the temperature of the fire source, achieving the effect of quickly extinguishing the fire source. It can quickly form a uniform water mist coverage layer when a fire occurs, widely covering the entire fire source area. Compared with traditional water sprinkler fire extinguishing devices, water mist is easier to penetrate and distribute evenly, and can quickly extinguish fires.
