Description

A cleaning nozzle sprayed in a whirlwind in the circumferential inclination direction {Nozzle used for cleaning}

The present invention relates to a washing nozzle, and more particularly, in an improved circumferential oblique direction so that the fluid injected from the nozzle is sprayed in a circumferential oblique direction while hitting a whirlwind, and at the same time it is sprayed while whirling in a lower straight direction as well, thereby greatly improving washing efficiency. It relates to a cleaning nozzle that is sprayed in a whirlwind

In general, since the cleaning nozzle is designed to discharge the fluid in only one direction from the front of the nozzle, there is a problem that the cleaning range is relatively narrow and limited.

Accordingly, the rotary nozzle as described in the patent document of the prior art document has been disclosed in the prior art, which is disclosed so that the range in which the fluid is sprayed while the nozzle head is rotated can have a relatively wide cleaning range.

However, in the prior art described above, since the nozzle head must be rotated by the fluid injection pressure, the structure is complicated and the cost is increased, and the nozzle must be inserted into a part that is invisible to the naked eye and washed. When the cleaning operation is performed in a relatively poor cleaning environment where the nozzle head is in contact with or collides with the cleaning material, the nozzle head cannot rotate and the failure rate is high.

The present invention will be described in more detail based on the accompanying preferred embodiments as follows.

Referring to Figure 1, the present invention is a washing nozzle (10) for washing by spraying water or compressed air, as an example, by mounting the washing nozzle (10) to the air injection pipe (Ga) of the air gun (G) compressed air to be discharged to be washed.

Therefore, the present invention, as shown in FIGS. 2 and 3, the injection part 12 having a connection part 11 having a fastening hole 11a and a fluid supply groove hole 13 communicating with the fastening hole 11a therein. is configured to provide

The injection unit 12 is in the form of a bead as shown in (a) of FIG. Alternatively, as shown in (a) of FIG. 3, the lower part of the cylindrical shape may be in the form of a cone, or the whole may be in the form of a cylinder, although not shown in the drawings.

As shown in Figs. 3 (b) and 4 (b), the injection unit 12 has a plurality of circumferentially inclined direction inclined discharge holes 14 and 14 that are in communication with the fluid supply groove 13 and are inclined in the circumferential direction. ', 14''), and the spiral tornado generating grooves 16 are respectively formed on the inner peripheral surfaces of the circumferentially inclined discharge holes 14, 14', 14''.

In order to help the understanding of the present invention, the washing nozzle is described with reference to FIG. 4 showing a planar cross-sectional view, in FIG. 4 (a) is a discharge hole formed in a straight direction in the injection unit 12, such a straight discharge hole ( When h) is formed, the fluid is discharged in a straight direction, but the present invention is such that an inclined discharge hole inclined in a circumferentially inclined direction is formed in the injection part 12 as shown in FIG. 4 (b), as shown in FIG. In order to help the understanding of the present invention that the discharge hole inclined in the circumferentially inclined direction is formed, it is defined and described as the circumferential inclined direction inclined discharge hole (14, 14', 14"), and as described above, the circumferential inclined direction inclined discharge When the balls 14, 14', 14" are formed, the fluid injected therefrom is injected at an oblique angle toward the circumferential inclination direction of the injection unit 12.

Therefore, the present invention is configured such that the spiral tornado generating groove 16 as shown in FIGS. 5 and 6 is further processed on the inner circumferential surface of the circumferentially inclined discharge holes 14, 14', 14" as described above.

Therefore, the fluid passing through the circumferentially inclined discharge holes 14, 14 ', and 14 "is in a state in which the fluid entering the spiral tornado generating groove 16 passes in a spiral way, and thereby the circumferentially inclined discharge hole The fluid discharged to (14, 14', 14") is sprayed in a swirling state while being sprayed at an oblique angle toward the circumferential inclination direction of the injection unit 12.

As described above, the circumferentially inclined discharge holes 14, 14' and 14" through which the fluid is injected at an oblique angle in the circumferentially inclined direction while swirling are, as shown in FIGS. 2 and 3, the middle part of the spraying part 12. A plurality of circumferentially inclined discharge holes 14 may be provided at equal intervals in the circumferential direction of It may be configured such that the circumferentially inclined direction inclined discharge holes 14 ′ inclined to be provided at equal intervals in the circumferential direction.

And the circumferentially inclined direction inclined discharge hole 14, the upper injection part 12 is further provided with circumferentially inclined direction inclined discharge holes 14'' that are inclined outward while facing the upper side at equal intervals in the circumferential direction. may be configured.

In addition, the lower portion of the injection unit 12 is configured to be provided with a central vertical discharge hole 15 having a spiral tornado generating groove 16 .

Therefore, preferably, in the injection unit 12, the circumferentially inclined discharge holes 14 and 14' having the spiral tornado generating groove 16 are provided in the middle and the lower side of the injection unit 12 at the same time as the spiral tornado generating groove 16 is provided at the bottom. Preferably, the central vertical discharge hole 15 with the groove 16 is provided together, and if necessary, the circumferentially inclined direction inclined discharge holes 14 and 14' and the central vertical discharge hole 15 are provided. It is preferable to use a cleaning nozzle 10 that is further provided with a circumferentially inclined discharge hole 14 ″ having a spiral tornado generating groove 16 toward the upper portion of the injection unit 12 while being used.

Therefore, the present invention is discharged to the circumferential inclined direction inclined discharge holes (14, 14', 14") having the spiral tornado generating groove 16 and the central vertical discharge hole 15 having the spiral tornado generating groove 16, respectively. Since the jetted fluid is in a state of being discharged while swirling, the fluid is jetted by the jetting force of the fluid, but the moment the jetted fluid touches the object, the rotational force is applied to the object. Therefore, a better cleaning action is promoted because the object is hit with a relatively stronger force than before, which was cleaned only by the fluid jetting force.

And the present invention will be described with reference to FIG. 7 in order to help the understanding of the present invention as the washing range is further widened.

Referring to Figure 7 (a), when cleaning the internal hole of a product such as a pipe (P) in the past, the air injection pipe (Ga) was inclined to spray compressed air, in this case the air injection pipe ( When compressed air is sprayed with Ga) at the center straight, the inner circumferential surface of the pipe (P) is not washed well, so as shown in the figure, the air spray pipe (Ga) was tilted to face the inner circumferential surface. Only the part (Pa) to which the pipe (Ga) faces was washed, and the opposite part (Pb) was not cleaned well or was not cleaned at all, so there was a problem that it had to be washed several times, as well as taking a long time to clean. A problem arose.

However, in the present invention, as shown in (b) of FIG. 7, the washing nozzle 10 mounted on the air injection pipe (Ga) is inserted into the inner hole of the pipe (P) in an upright state in the center, or as shown in the drawing As shown, the entire inner circumferential surface of the pipe (P) is washed in any state, whether it is inserted obliquely or obliquely.

That is, in the present invention, when the cleaning nozzle 10 is inserted into the inner hole of the pipe (P) and the cleaning is performed, the compressed air discharged from the circumferentially inclined discharge holes 14 and 14' as shown in FIG. 5 is a tornado. Since the compressed air is discharged obliquely in the circumferentially inclined direction while hitting, the compressed air is rotated along the inner circumferential surface of the inner hole of the pipe (P), thereby rotating in the lower direction of the inner hole of the pipe (P) as shown by the arrow in FIG. It is in a state of being sprayed while exercising, and the entire inner circumferential surface of the pipe (P) is washed. In addition, the compressed air discharged while swirling from the central vertical discharge hole (15) removes foreign substances from the inner circumferential surface of the pipe (P) in the downward direction. It pushes and moves.

Therefore, the present invention inserts the washing nozzle 10 mounted on the air injection pipe (Ga) into the inner hole of the pipe (P) in an upright state in the center or in a state of being inserted obliquely as shown in (b) of FIG. Because the entire inner circumferential surface of the pipe (P) is washed in any insertion state in the liver, excellent, quick and easy cleaning is achieved.

8 is a view showing another washing state of the present invention, for example, in Ejin (ㄸ) having a complicated structure, the front part (Ea) is exposed to the outside and the rear part (Eb) is not exposed to the outside and only sideways open engine parts In the case of washing the engine (E), there is a problem that only the front part (Ea) of the engine parts is washed and the rear part (Eb) cannot be washed because the fluid is sprayed only in a straight direction in the past. However, if there is no space for the nozzle to enter, there is a problem that it cannot be cleaned at all.

However, in the present invention, as shown by the arrow in FIG. 8, the compressed air discharged from the circumferentially inclined discharge holes 14, 14', 14" is discharged in the circumferentially inclined direction while swirling, so that the compressed air is next to the engine parts. Compressed air enters through the hole in the hole, and the back side (Eb) can be washed, of course, even if there is no space to insert the washing nozzle 10, the compressed air is sprayed in the vicinity of the washing nozzle 10 If possible, the compressed air is discharged in the circumferential oblique direction as it swirls, so the compressed air is sprayed even to the part where the nozzle is not inserted, so that the part that has not been cleaned before can be cleaned well, thereby improving the cleaning ability. and the cleaning range is greatly expanded.

The present invention is not necessarily limited to what has been shown and described in the drawings and may be modified in various forms by those of ordinary skill in the art to which the present invention pertains, so it should be broadly protected as long as it does not significantly depart from the scope of the claims. thing is self-evident.
