Description

The present disclosure relates to a nozzle structure of a watering apparatus, and more specifically to a rotor nozzle structure which has the advantages of easy assembly and stable operation.

The conventional rotor nozzle structure as disclosed in Patent Document 1 is a conical chamber 3 as an accommodating portion of a cylindrical rotor 12, and the rotor 12 is a water outlet hole connected to an outlet opening 6 of a spray gun. A conical chamber 3 having an unfolded end having a 14 and an intermediate having a spherical surface with respect to the inner wall of the conical chamber 3 of the rotor 12 in an eccentric arrangement with respect to the longitudinal axis of the conical chamber 3. The housing 2 having the element 25 is disclosed. In this structure, when the fluid flows into the chamber 3, the fluid rotates the rotor 12 in an inclined flow, then changes to a 360-degree vortex flow, and flows out from the outlet opening 6. However, since this type of rotor 12 of the rotor nozzle also rotates in the chamber 3, the output fluid is dispersed.

U.S. Pat. No. 9931652

It is an object of the present disclosure to employ a longitudinal chamber for application to handy spray guns and to provide a rotor nozzle that prevents rotation of the rotor so that the output fluid is concentrated.

Based on the above-mentioned objectives, the present disclosure provides a structure of a rotor nozzle installed in a spray unit of a watering device. The spray unit consists of mounting members and a housing that mutually define a chamber with one water inlet and one water outlet, and the chamber is deployed with the rotor with respect to that end of the water outlet that connects to the water outlet side. .. At least one stopper set inside the chamber near the water outlet side is fitted corresponding to the plurality of guide members at the end of the water outlet of the rotor.

Thanks to the deployment of the stopper, the stopper secures the rotor in an inclined arrangement and does not require the conventional conical chamber applied to existing spray nozzles.

In addition, the rotor has a spherical end that connects to the water outlet of the watering device. Therefore, the water outlet side of the rotor forms at least two annular positioning areas. The present disclosure further provides a watering device for accommodating the above-mentioned structure of the rotor nozzle.

It is a perspective view of the embodiment of the present disclosure. It is sectional drawing in embodiment of this disclosure. It is an exploded view in embodiment of this disclosure. FIG. 3 is an exploded cross-sectional view of FIG. 3 in the embodiment of the present disclosure. It is another exploded view in embodiment of this disclosure.

Hereinafter, for better understanding by those skilled in the art, the water outlet of the adjustable watering device will be described in order to consider the embodiments of the present disclosure more specifically.

1 to 4 show the spray unit 100 of the watering device. The spray unit 100 is rotatably installed on the base 200 of the watering apparatus and is mainly assembled correspondingly by the adjusting member 10 and the mounting member 11.
A plurality of spray heads are set between the adjusting member 10 and the mounting member 11, the spray head has a water outlet and a water inlet between the adjusting member 10 and the mounting member 11, respectively, and the mounting member 11 sprinkles water. The base 200 of the device is connected to the water inlet side 101, and the water inlet side 101 is connected to the water supply unit. Therefore, due to the relative rotation between the spray unit 100 and the base 200 of the watering device, one of the spray heads can be connected to the water inlet side 101 of the base 200 from the water supply unit. Water flows into the rotor nozzle through the water inlet side 101 and is discharged from the water outlet side 102.

One of the spray heads has a rotor nozzle structure, and the rotor nozzle structure includes a housing 15, a rotor 20, and a flow guiding portion 40. In this case, the housing 15 has a substantially tubular shape in which the front end thereof engages with the inner side wall of the adjusting member 10, whereby the water outlet side 102 of the housing 15 is positioned on the adjusting member 10, and the housing 15 is: The rear end is connected to the mounting member 11 so as to define the chamber 17 with each other by the inside in the longitudinal direction.

The diversion portion 40 has an annular base 41 located at the rear opening of the housing 15 and a block 12 on the side wall of the mounting member 11, whereby the diversion portion 40 and the bottom of the mounting member 11 are partitioned. ) Is arranged. In addition, the flow guiding portion 40 includes a central base 45 separated from the annular base 41, a positioning rod 47 projecting forward from the central base 45 in the direction of the water outlet 102, and the inside of the annular base 41. It has a plurality of guide blades 43 connected to the side wall and the outer side wall of the central base 45, and the guide blades 43 are tangent to the central base 45 at a predetermined angle along the radial direction of the central base 45. Extending in the direction, a swivel opening 46 is defined between adjacent guide blades 43. In other words, the swivel opening 46 is arcuate and penetrates the two opposite sides of the annular guide 40.

The rotor 20 is installed in the chamber 17 and forms a hollow column having two ends as a water inlet 21 and a water outlet 22. In this case, the rotor 20 has an inner side wall to which a plurality of flow blades 26 extending to the water inlet 21 in an intersecting manner are fixed. The rotor 20 has a spherical end 27 composed of a water outlet 22 connected to the water outlet side 102 of the adjusting member 10, and the spherical end 27 and the water outlet side 102 form a complementary mechanism. .. In addition, the rotor 20 is confined in an eccentric arrangement between the inner wall of the chamber 17 and the annular track of the positioning rod 47 of the guide 40 with respect to the rotor 20 and tilts rearward and outward to the water outlet. It has an entrance 21.

In the present disclosure, the chamber 17 near the water outlet side 102 is inside in the longitudinal direction having a plurality of stoppers 18 protruding in an annular shape on the inner side wall, slots 19 are formed between the stoppers 18, and a plurality of stop rods. Discloses an embodiment in which the guide member 28 projects radially over the spherical end 27 of the rotor 20 and is positioned in the slot 19. In addition, each stopper 18 has a bevel on its surface that guides the surface of the rotor 20 in an inclined arrangement, and the water outlet side (spherical end 27, guide member 28) of the rotor 20 has at least two annular rings. Form a position area of. The rotor 20 rotates stably, and the rotor 20 rotates because it produces a concentrated linear flow ejected from the water outlet 22 of the rotor 20 instead of the conical ejection generated by the conventional rotation of the rotor. Prevent it from happening.

It is worth mentioning that the positioning rod 47 of the flow guide 40 is in line with the water inlet side 101 and the water outlet side 102. The rod body 25 extends from one end of the water inlet 21 of the rotor 20 along the rear end of the flow blade 26 so that it is positioned on the outer wall of the positioning rod 47, thereby stabilizing the rotational trajectory of the rotor 20. ..
When the water in the water supply section flows from the water inlet side 101 to the swirling opening 46 of the flow guide section 40, the inclined flow generated in the chamber 17 drives the rotor 20 to rotate, and the fluid flows from the water inlet 21 of the rotor 20. It flows through the spray unit 100 to the water outlet side 102, and the swirling flow is output by the rotation of the rotor 20.

See FIG. FIG. 5 shows a spray unit of another watering device. In this embodiment, a bevel is set in the chamber near the water inlet side 101 to guide the surface behind the rotor 20. The chamber near the water outlet side 102 has an inside in the longitudinal direction, and three stoppers 18 projecting from the inner side wall thereof are arranged at an equal angle. A plurality of slots are radially arranged at the water outlet of the rotor 20 in an annular shape, the slots are provided as guide members for arranging the stopper 18, and thus the rotor 20 is arranged in an inclined manner thereof. It rotates stably with the rotor 20 and prevents the rotor 20 itself from rotating.

The present disclosure provides an embodiment in which the number of guide members 28 is a multiple of an integer of the number of stoppers 18 in order to maintain rotational balance. However, the number of stoppers 18 can be only one to position the rotor 20.
