The specific embodiments of the present invention will be further described by the following examples and accompanying drawings.

Please refer to FIG. 1 to FIG. 4, which are side views showing a swirling injection device according to an embodiment of the present invention, and FIG. 2 is an exploded view showing the swirling injection device of FIG. 1, FIG. A partial cross-sectional view of the swirling injection device of Fig. 1 is shown, and a partially enlarged view of Fig. 3 is shown for the fourth drawing.

As shown, a cyclonic spray apparatus 100 according to an embodiment of the present invention includes a spray device body 1, a spray casing 2, and a swirling nozzle 3.

The spray device body 1 is used to connect a fluid supply source (not shown) to obtain a supply of fluid. The spray device body 1 includes a control handle 11 in the present embodiment, and an adjustment mechanism 111 is disposed in the control handle 11. The adjustment mechanism 111 functions as the same valve, and can regulate the flow rate of the fluid F input from the fluid supply source to the injection device body 1, or stop the fluid F from entering the injection device body 1 by closing.

The injection sleeve 2 is a hollow tube body for the swirling nozzle 3 to be inserted, and one side thereof is fixed to the spray device body 1.

The swirling nozzle 3 includes a conveying pipe body 31 and a bent pipe body 32 connected thereto. In the present embodiment, the conveying pipe body 31 is screwed to the bent pipe body 32, so that the two can be easily assembled and detached, and has better bonding stability.

The conveying pipe body 31 is disposed in the injection casing 2, and the conveying pipe body 31 is sleeved with a front bearing 41 near one side of the bending pipe body 32, and the other The side sleeve is provided with a rear bearing 42. Thereby, the swirling nozzle 3 can be rotated with respect to the injection sleeve 2 by the front bearing 41 and the rear bearing 42. Specifically, the transport tube body 31 is fluidly connected to the injection device body 1, and the fluid F is introduced into the transport tube body 31 through the spray device body 1, and is then ejected outward through the bent tube body 32. The bent pipe body 32 is an angularly eccentric pipe body that is rotated and rotated by the force of the fluid F flowing through the bent pipe body 32, thereby causing the fluid F to face in all directions along with the rotation of the swirling nozzle 3. ejection.

In the present embodiment, the front bearing 41 and the rear bearing 42 are disposed to abut against the inner annulus 20 of the injection sleeve 2. However, in other embodiments, the front bearing 41 and the rear bearing 42 may be disposed to abut against the end faces of the injection sleeve 2. Alternatively, the front bearing 41 and the rear bearing 42 may be disposed to abut against other components of the swirling spray device 100, such as the spray device body 1.

Preferably, in order to prevent the friction between the bearings from colliding with each other, the inner annular surface 20 of the injection sleeve 2 is convexly provided with a spacing portion 21 between the front bearing 41 and the rear bearing 42. The spacer portion 21 is a ring body in this embodiment, which is convenient to manufacture, but may also be a bump or other configuration. In addition, the injection sleeve 2 further includes a front fixing member 22 disposed on the inner annular surface 20 of the injection sleeve 2 and abutting against the front side of the front bearing 41 to be fixed by the spacer 21 and the front portion. The piece 22 fixes the position of the front bearing 41.

Further, in a preferred embodiment, the portion 23 of the injection sleeve 2 that faces the outer ring from the outer bearing 41 and the rear bearing 42 is a solid structural body. That is, the portion 23 is a solid structure that is dense and has no holes. Thereby, it is possible to have a better structural strength and provide sufficient supporting force to make the rotation of the swirling nozzle 3 more stable.

The swirling nozzle 3 has a front limiting portion 33 and a rear limiting portion 34. The front limiting portion 33 protrudes radially from the swirling nozzle 3 and blocks the front bearing 41 On the front side, the rear limit portion 34 projects radially to the swirling nozzle 3 and blocks against the rear side of the rear bearing 42. Thereby, on the one hand, the axial movement of the swirling nozzle 3 can be restricted, so that the swirling nozzle 3 is not detached from the injection sleeve 2, and on the other hand, the front bearing 41 and the rear bearing 42 are also restricted to reduce undesired Displacement and vibration. Preferably, there is a gap between the swirling nozzle 3 limited by the front limiting portion 33 and the rear limiting portion 34 and the ejection device body 1 so that friction does not occur between the two to maintain rotation. Smooth. In addition, for the convenience of manufacture, the front limiting portion 33 and the rear limiting portion 34 are a ring body in this embodiment, but may also be a bump or other configuration as long as the effect of blocking the front and rear bearings 41, 42 can be provided. .

In the present embodiment, the front limit portion 33 is located at the bent pipe body 32, and the rear limit portion 34 is positioned at the transport pipe body 31. In this way, the front bearing 41 and the rear bearing 42 can be blocked by the separation and combination of the conveying pipe body 31 and the bent pipe body 32 so that the front limiting portion 33 and the rear limiting portion 34 are assembled. Further, in the present embodiment, the front stopper portion 33 is integrally formed with the bent pipe body 32, and the rear stopper portion 34 is integrally formed with the conveying pipe body 31 in this embodiment. Therefore, not only the front stopper portion 33 and the bent pipe body 32, the rear stopper portion 34, and the conveying pipe body 31 can be manufactured together, thereby reducing the total number of parts and accelerating the production speed. At the same time, there is no case where the front and rear stopper portions 33, 34 are separated from the bent pipe body 32 and the conveying pipe body 31.

In order to prevent the swirling nozzle 3 from being damaged by the foreign object, the spray sleeve 2 is combined with a horn sleeve 5 on the front side, which surrounds the bent tubular body 32 of the swirling nozzle 3. Moreover, the horn sleeve 5 can also concentrate the fluid F ejected from the gyro nozzle 3 to improve the cleaning effect.

Referring to Figure 5, there is shown a partial cross-sectional view of a swirling spray device in accordance with another embodiment of the present invention. The constituent elements of the cycloiding apparatus 100a of this embodiment are the same as those of the foregoing embodiment, and the same elements are denoted by the same element numbers. This embodiment and the foregoing embodiment The difference is that the swirling spray device 100a further includes a first-stage inner tube 6. An output end 61 of the fluid inner tube 6 is passed through the swirling nozzle 3 and extends through the conveying tube body 31 to the nozzle of the bent tubular body 32. An input end 62 of the fluid inner tube 6 extends through the spray device body 1 to a water delivery mechanism 12.

With such a configuration, when the fluid F flows through the swirling nozzle 3, a Venturi effect is generated at the nozzle of the bent tubular body 32. By this effect, the water accommodated in the water delivery mechanism 12 is sucked into the fluid inner tube 6 and is output from the output end 61 of the fluid inner tube 6. Thereby, the fluid F is mixed with water at the nozzle of the bent pipe body 32 to be ejected outward.

It can be seen from the above embodiments that the rotary jetting device provided by the present invention has industrial utilization value, so the original operation has been in conformity with the requirements of the patent. However, the above description is only for the preferred embodiment of the present invention, and those skilled in the art can make other improvements according to the above description, but these changes still belong to the novel spirit of the creation and the following definitions.
