Nozzle improvement structure

This creation is related to the nozzle structure, especially a nozzle provided at the outlet of the high pressure vessel.

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.

The main purpose of the present invention is to provide a nozzle-improving structure in which a spiral twist line is provided on the inner wall surface surface to accelerate the ejection speed of the container contents and increase the range and breadth of the spray range.
To achieve the foregoing objectives, the present invention provides a nozzle improved structure including:
a body having an inlet end and an outlet end, the inside of the body is provided with a flow passage extending from the inlet end to the outlet end, and the flow passage is gradually expanded from the inlet end toward the outlet end;
a set of joints disposed at the inlet end of the body;
a baffle disposed in the flow channel, wherein the baffle is provided with a plurality of perforations;
a rail groove is disposed on a peripheral wall of the flow channel; the rail groove extends spirally from the inlet end toward the outlet end.
The above objects and advantages of the present invention are not to be understood in detail from the detailed description and the accompanying drawings.

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.
