噴嘴改良結構Nozzle improvement structure

　　本創作與噴嘴結構有關，尤指一種設於高壓容器之出口的噴嘴。
This creation is related to the nozzle structure, especially a nozzle provided at the outlet of the high pressure vessel.

　　按，高壓容器(如滅火器)之出口設有噴嘴結構，用以輔助內容物噴出的速度、方向及噴灑射程、範圍等。噴嘴結構的設計對內容物的噴灑狀態有極大的影響，例如第５圖所示之習知噴嘴２，其內部具有一呈漸縮的流道２１，俾供高壓內容物通過該流道２１時產生集中且加壓的效果，令內容物呈集束狀噴出，此種噴嘴可獲得射程較遠的優點，惟噴灑範圍則較為集中。
　　另一種習知噴嘴如第６圖所示者，其於噴嘴３之流道３１中設有一阻擋件３２，使噴嘴３之出口形成環狀，據此令內容物呈環狀噴出，而可達到噴灑範圍較廣的優點。惟由於受到該阻擋件３２之阻擋，故噴出的速度及射程皆較低。
　　上述兩種習知的噴嘴各有優缺，然而卻無法同時兼顧射程遠及噴灑範圍廣的特性，實有待改進。
　　有鑑於此，故如何改進上述問題，即為本創作所欲解決之首要課題。
According to the outlet of the high-pressure vessel (such as a fire extinguisher), a nozzle structure is provided to assist the speed, direction, spray range and range of the contents. The design of the nozzle structure has a great influence on the spray state of the contents, such as the conventional nozzle 2 shown in Fig. 5, which has a tapered flow path 21 therein for the passage of the high pressure contents through the flow path 21. The effect of concentration and pressure is generated, so that the contents are sprayed in a bundle shape, and such a nozzle can obtain the advantage of a longer range, but the spray range is more concentrated.
Another conventional nozzle, as shown in FIG. 6, is provided with a blocking member 32 in the flow path 31 of the nozzle 3, so that the outlet of the nozzle 3 is formed into a ring shape, thereby causing the contents to be ejected in a ring shape. The advantage of a wide range of sprays. However, due to the blocking by the blocking member 32, the speed and range of the ejection are low.
The above two conventional nozzles have advantages and disadvantages, but it is impossible to simultaneously take into consideration the characteristics of the range and the wide range of spraying, which needs to be improved.
In view of this, how to improve the above problems is the primary issue that the creative office wants to solve.

　　本創作之主要目的在於提供一種噴嘴改良結構，其於內側壁面設有螺旋狀之膛線，藉以加速容器內容物噴出的速度，增加噴灑範圍的射程與廣度。
　　為達前述目的，本創作提供一種噴嘴改良結構，其包括有：
　　一本體，其具有一入口端及一出口端，該本體之內部設有一自該入口端貫通至該出口端之流道，且該流道自該入口端朝該出口端呈漸擴狀；
　　一套接部，其設於該本體之入口端；
　　一擋板，其設於該流道中，其中該擋板設有數個穿孔；
　　一軌槽，其設於該流道之周壁；該軌槽自該入口端朝該出口端呈螺旋狀地延伸。
　　而本創作之上述目的與優點，不難從下述所選用實施例之詳細說明與附圖中獲得深入了解。

　　請參閱第１、２圖，所示者為本創作所提供之噴嘴改良結構，其包括有一筒狀本體１，其具有一入口端１１及一出口端１２，且該本體１之內部設有一自該入口端１１貫通至該出口端１２之流道１３。該流道１３自該入口端１１朝該出口端１２呈漸擴狀；亦即該入口端１１之口徑小於該出口端１２之口徑。
　　承上，該本體１之入口端１１處設有一套接部１４，俾供套接一外部高壓容器，如滅火器等，藉以引導高壓容器之內容物進入該流道１３。又如第３圖所示，該流道１３中設有一擋板１５，其橫阻於該流道１３，而該擋板１５設有數個穿孔，其中包括有位於該擋板１５中央之第一穿孔１５１，以及數個環設於該第一穿孔１５１周圍之第二穿孔１５２，藉由這些穿孔使該流道１３仍為暢通狀態。此外，該流道１３之周壁設有一軌槽１６，其中該軌槽１６自該入口端１１朝該出口端１２呈螺旋狀地延伸。
　　藉由上述結構，使用本創作時如第４圖所示，將該套接部１４接設於一外部的高壓容器，則此高壓容器中的內容物可自該入口端１１進入該流道１３。此時該流道１３充滿內容物，其中可界定區分為兩個部分，第一部分（以箭頭Ａ表示）靠近該軌槽１６並形成環狀分布，餘者為第二部分（以箭頭Ｂ表示），其靠近流道１３中心處。上述前者將受到該軌槽１６之引導而沿該軌槽１６呈螺旋狀地前進，而後者則未受到該軌槽１６之影響而以直線方向前進。
　　進一步言之，第一部分之內容物將於行進至該出口端１２後以環狀噴灑而出，藉以達到廣範圍的噴灑效果；另一方面，第一部分之內容物同時藉由螺旋狀的位移獲得加速的效果，而增加噴出的射程距離。而第二部分之內容物則沿直線前進，其行進速度則依容器壓力而定，一般而言，其具有較遠的射程距離。因此，綜合兩部分內容物的噴灑表現，皆可達到射程遠的效能，且同時兼具廣範圍的噴灑效果。
　　又當內容物經過該擋板１５時，雖可經由該第一穿孔１５１及該第二穿孔１５２而通過該擋板１５，但仍會受到一些阻擋而產生擾流，若本創作所連接者為滅火器，則滅火器之內容物遇到該擋板１５可產生泡沫，藉此可得到更佳的滅火效果。
　　惟，以上實施例之揭示乃用以說明本創作，並非用以限制本創作，故舉凡等效元件之置換仍應隸屬本創作之範疇。
　　綜上所述，可使熟知本項技藝者明瞭本創作確可達成前述目的，實已符合專利法之規定，爰依法提出申請。
Referring to Figures 1 and 2, the nozzle improved structure provided by the present invention includes a cylindrical body 1 having an inlet end 11 and an outlet end 12, and the interior of the body 1 is provided with a self. The inlet end 11 extends through the flow passage 13 of the outlet end 12. The flow path 13 is gradually divergent from the inlet end 11 toward the outlet end 12; that is, the diameter of the inlet end 11 is smaller than the diameter of the outlet end 12.
The inlet end 11 of the body 1 is provided with a set of joints 14 for receiving an external high-pressure vessel, such as a fire extinguisher, to guide the contents of the high-pressure vessel into the flow passage 13. As shown in FIG. 3, the flow path 13 is provided with a baffle 15 which is transversely opposed to the flow path 13, and the baffle 15 is provided with a plurality of perforations including the first one located at the center of the baffle 15. The through hole 151 and the plurality of second through holes 152 disposed around the first through hole 151, the flow path 13 is still in a clear state by the through holes. Furthermore, the peripheral wall of the flow channel 13 is provided with a rail groove 16, wherein the rail groove 16 extends helically from the inlet end 11 towards the outlet end 12.
With the above structure, when the present invention is used, as shown in FIG. 4, the socket portion 14 is connected to an external high-pressure container, and the contents of the high-pressure container can enter the flow path 13 from the inlet end 11. . At this time, the flow channel 13 is filled with the contents, wherein the partition can be divided into two parts, the first part (indicated by the arrow A) is close to the track groove 16 and forms an annular distribution, and the remainder is the second part (indicated by the arrow B). It is near the center of the flow channel 13. The former is guided by the rail groove 16 and spirally advanced along the rail groove 16, while the latter is not linearly moved by the rail groove 16 to advance.
Further, the contents of the first portion will be sprayed in an annular shape after traveling to the outlet end 12, thereby achieving a wide range of spraying effects; on the other hand, the contents of the first portion are simultaneously obtained by helical displacement. Accelerate the effect and increase the range distance of the jet. The contents of the second part proceed in a straight line, and the speed of travel depends on the pressure of the container. In general, it has a longer range distance. Therefore, the combined performance of the two parts of the content can achieve a long range of performance, and at the same time a wide range of spraying effects.
When the content passes through the baffle 15, the baffle 15 can pass through the first through hole 151 and the second through hole 152, but the blockage is still blocked, and the spoiler is generated. In the case of a fire extinguisher, the contents of the fire extinguisher encounter the baffle 15 to generate a foam, thereby obtaining a better fire extinguishing effect.
However, the disclosure of the above embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of this creation.
In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
