Please refer to FIG. 1 and FIG. 2, FIG. 1 is a front elevational view showing an embodiment of the present fire extinguisher apparatus, and FIG. 2 is a schematic cross-sectional view showing an embodiment of the present fire extinguisher head. The high-efficiency atomized liquid fire extinguisher nozzle 1000 disclosed in the present application is applicable to a fire extinguisher device 2000; the fire extinguisher device 2000 has a fire extinguishing agent 6, a fire extinguisher valve 8 and a fire extinguisher bottle body 5, and the fire extinguishing agent 6 is placed in the fire extinguisher bottle body 5 Inside, the fire extinguisher valve 8 is mounted to the fire extinguisher bottle body 5 to control the holding or venting of the fire extinguishing agent 6. The fire extinguisher nozzle 1000 includes a nozzle housing 1 coupled to the fire extinguisher valve 8, a nozzle member 2 mounted on the nozzle housing 1, and a plurality of spoiler structures 3 for atomizing the fire extinguishing agent 6, wherein the nozzle housing 1 A casing flow path 11 is formed therein.

In an embodiment of the present invention, the nozzle member 2 includes a first threaded structure 24, and the head housing 1 includes a second threaded structure 14 through which the nozzle member 2 is locked by the first threaded structure 24 and the second threaded structure 14. Attached to the nozzle housing 1 (as shown in FIG. 2); in this embodiment, the first thread structure 24 can be an external thread structure, and the second thread structure 14 can be an internal thread structure. The manner of combining the member 2 and the head housing 1 is not limited to that shown in the drawings of the embodiment. For example, the nozzle member 2 and the head housing 1 can also be combined by riveting, engaging, fitting or welding. . It is worth mentioning that in order to achieve the sealing effect between the nozzle member 2 and the head housing 1, the interference fit or welding between the nozzle member 2 and the head housing 1 can be achieved depending on actual needs.

The nozzle member 2 of the present fire extinguisher nozzle 1000 is formed with a plurality of accommodating chambers 21, a plurality of cone chambers 22 (or vortex chambers), and a plurality of nozzle ports 23, and the plurality of accommodating chambers 21 are connected to the shell. The body flow channel 11 and each of the accommodating chambers 21 are in communication with one of the plurality of cone chambers 22, the plurality of nozzle openings 23 corresponding to the plurality of cone chambers 22, and the nozzle ports 23 are connected to the plurality of nozzles One of the cone chambers 22. When the fire extinguisher device 2000 is used for fire extinguishing, the fire extinguishing agent 6 from the fire extinguisher bottle body 5 is sequentially driven by the pressure, and sequentially flows through the shell flow passages 11 connected to each other, the plurality of accommodating chambers 21, and a plurality of The cone chamber 22 is ultimately ejected by a plurality of nozzle openings 23 at the end of the fire extinguisher nozzle 1000 and forms a highly atomized mist curtain. Compared with the conventional single-nozzle fire extinguisher nozzle form, the present fire extinguisher nozzle 1000 is provided with a plurality of nozzle openings 23 at the front end of the fire extinguisher nozzle 1000, so that the sprayed mist curtain has a more uniform cross-sectional flow distribution (as shown in FIG. 3). Show).

Please refer to Figure 9 and Figure 3, Figure 9 is a schematic diagram showing the cross-sectional flow distribution of the fire-extinguishing agent spray curtain sprayed by the general fire extinguisher nozzle, and Figure 3 is the cross-sectional flow distribution of the fire-extinguishing agent spray curtain sprayed by the liquid fire extinguisher nozzle. schematic diagram. Once the spray is ejected from the nozzle opening, the mist formed by the spray spreads along a apex in the cone-shaped range of the nozzle opening (the vertebra angle of the vertebra, the so-called spray angle); in the direction of the spray If the unit flow rate in a radial direction of a cross section of the mist curtain (the flow rate per unit area per unit area) is taken at a certain distance from the nozzle opening, it can be summarized as a cross-sectional flow distribution map. . The horizontal axis of the cross-sectional flow distribution map essentially represents the coordinates of each point in the radial direction with respect to the center of the section. All radial coordinates are symmetrical with the center of the section as the origin (ie, the center of the horizontal axis); the longitudinal axis of the cross-sectional flow distribution diagram Essentially represents the value of the unit flow received at each point in the radial direction (or the ratio of the flow rate further divided by the value of the nozzle port unit flow). Therefore, the cross-sectional flow profile can exhibit a difference in the flow rates received between the different radial coordinates, and a distribution trend of the cumulative cumulative flow of the fog curtain in the radial direction. As shown in Fig. 9, the flow distribution curve in the figure shows a peak near the origin, but shows a decreasing trend on both sides of the origin; in contrast, the flow distribution curve shown in Fig. 3 is at the left and right of the origin. The range of the side is substantially maintained at a constant value, and the cumulative flow rate of the entire fog screen does not decrease as the distance from the origin increases. For the effectiveness of fire extinguishing, the more the unit flow can be increased in the larger the cross section of the fog curtain, the more effective it is to extinguish the fire. As shown in the flow distribution curve shown in Fig. 3, the range in which the maximum value per unit flow rate is substantially flat covers almost the entire radial extent of the cross section, as covered by the extreme value of the flow distribution curve shown in Fig. 9. It is much narrower than it is. Therefore, compared with the general fire extinguisher nozzle, the liquid fire extinguisher nozzle of the present invention can provide a more uniform mist curtain, so that it can also produce better fire extinguishing effect.

In order to allow the fire extinguisher to extinguish a certain scale of fire under a limited dose, the regulations stipulate that the bottled fire extinguisher must spray more than 85% of the bottle in a certain period of time, while still maintaining a certain degree of fog curtain insulation and fire extinguishing efficiency; Therefore, considering the two factors of the medicine injection distance (ie, the range) and the injection duration (related to the unit flow rate), in the embodiment of the present creation, the number of nozzle openings 23 of the fire extinguisher nozzle 1000 may be 3 holes, 4 Holes or 5 holes correspond to the capacity of the fire extinguisher bottle 5 of "1 or 2 liters", "2 or 3 liters", and "6 or 9 liters".

Please refer to FIG. 4, which is a partially enlarged schematic view of the accommodating chamber, the cone chamber and the nozzle opening of the fire extinguisher nozzle. As shown in Fig. 4, the aperture of the nozzle opening 23 is smaller than the inner diameter of the corresponding accommodating chamber 21, and a diameter of the nozzle opening 23 is 1 mm or more and 5 mm or less. In addition, the cone chamber 22 of the nozzle member 2 is substantially a truncated conical chamber, and the accommodating chamber 21 is substantially a cylindrical chamber, a side 220 of the truncated conical chamber and the cylinder A side angle 210 of the cavity has an angle θ, and the angle θ is between 100 degrees and 160 degrees, that is, the angle θ is between 20 degrees and 80 degrees, that is, the cone An acute angle between the larger end of the chamber 22 and a length direction of the head housing 1 is between 20 and 80 degrees. As a result, the aforementioned special size setting can effectively increase a range of the fire extinguishing agent 6 under the limited pressure of the limited fire extinguisher device 2000. For general accumulators, the internal pressure of the fire extinguisher is usually between 8 kgf / cm ² ~ 15 kgf / cm ² (in the medium and low pressure), with the fire extinguisher nozzle 1000 of this creation, the range of the fire extinguishing agent 6 Still up to 3~6 meters away, it is enough for the user to maintain a long enough safe distance from the fire source and still ensure that the fog screen sprayed by the fire extinguisher device 2000 has good fire extinguishing performance and insulation ability.

The plurality of spoiler structures 3 of the present fire extinguisher nozzle 1000 are respectively disposed in a plurality of accommodating chambers 21. In an embodiment of the present invention, the spoiler structure 3 is a turbine structure (as shown in FIG. 2), the turbine structure includes a plurality of spoiler blades 31 and a plurality of split channels 32, and the plurality of split channels 32 are spaced apart Formed between the plurality of spoiler blades 31, that is, each of the diverting channels 32 is formed between the two spoiler blades 31, and the plurality of diverting channels 32 communicate with the casing flow channel 11 and the corresponding conical cavity chamber 22, in order to rotate the fire extinguishing agent 6 flowing through the split channel 32. In this way, the degree of atomization of the fire extinguishing agent 6 can be effectively improved by the above-described swirling mechanism.

In a further embodiment of the present invention, the spoiler structure 3 is movably disposed in the accommodating chamber 21 of the nozzle member 2; for example, an outer diameter of the spoiler structure 3 (such as the spoiler structure 3) A diameter of a cross section or a widest dimension of the cross section may be smaller than an inner diameter of the accommodating chamber 21, that is, a fit between the accommodating chamber 21 and the spoiler structure 3 corresponds to a hole shaft fit. The loose fit allows a gap to exist between a side surface 30 of the spoiler structure 3 and a side surface 210 of the accommodating chamber 21 (as shown in FIG. 2) so that the spoiler structure 3 can The accommodating chamber 21 rotates. In the foregoing configuration, the spoiler structure 3 may further have a rotating shaft 33 (as shown in FIG. 2). The plurality of spoiler blades 31 extend in the radial direction of the rotating shaft 33 to the rotating shaft 33, and the spoiler structure 3 can revolve around the rotating shaft 33. Rotating to cause a plurality of spoiler blades 31 to disturb the fire extinguishing agent 6 flowing through the accommodating chamber 21. In this way, in addition to the swirling effect provided by the turbine structure of the spoiler structure 3 itself, the additional rotation of the spoiler structure 3 can effectively increase the degree of swirl of the fire extinguishing agent 6, and further increase the atomization degree of the fire extinguishing agent 6. According to the conventional test results, the particle size of the water mist generated by the liquid fire extinguisher must be less than or equal to 150 μm to ensure good insulation in the case of extinguishing electrical fires; the accumulator type fire extinguisher is matched with the fire extinguisher nozzle of the present invention.

The medicament 6 leaks from the casing flow path 11 through a gap between the nozzle member 2 and the head housing 1, thereby maintaining the injection pressure of the extinguishing agent 6. In addition, it is to be noted that the sealing effect between the nozzle member 2 and the head housing 1 can be achieved by the arrangement of the sealing gasket structure (such as a sealing ring) as described above, and between the nozzle member 2 and the head housing 1 Interference fit or weld, as well as other seals with equivalent sealing.
