Description

Nozzle structure and watering device

Technical Field

The present invention relates to a sprinkler structure and a sprinkler, and more particularly, to a sprinkler structure and a sprinkler integrated to output a direct or rotational water flow.

Background

In the prior art rotary nozzle, for example, US9931652, a conical chamber (3) is arranged inside a housing (2) to accommodate a cylindrical shaft (12), one end of the shaft (12) is provided with a water outlet (14) connected to a water outlet end (6) of a water spraying gun, and the circumferential surface of the shaft (25) is abutted against the inner wall of the conical chamber (3), so that the shaft (12) is inclined from the long axis of the conical chamber (3). Therefore, when water flows into the chamber (3), the lateral water flow drives the shaft center (12) to rotate, so that the water flow flowing out of the water outlet end (6) through the shaft center (12) is a 360-degree rotating water flow.

If the nozzle is integrated to provide both rotational flow and linear flow, such as TW I611846, the lateral swirling flow channel (6c) is formed on both sides of the nozzle, and the openings (6b) of the lateral flow are also disposed on both ends of the opening (6a) of the linear flow.

Disclosure of Invention

In view of the above, a primary objective of the present application is to provide a nozzle structure, in which a chamber of the nozzle structure is provided with an axis communicated with a water outlet and an adjusting component, wherein the water outlets of the nozzle structure providing direct water flow or rotational water flow are the same; and the adjusting component is rotationally switched to enable the shaft center to rotate or not rotate in the chamber.

Further, the water inlet of the chamber has a fixed base and a movable base. The adjusting component is slightly T-shaped and is provided with a positioning area and a file stopping area which is protruded from the middle section of the positioning area, the positioning area is pivoted on the movable base and is abutted against the fixed base, so that the file stopping area stops files or forms a circular track at the water inlet end of the axis.

Furthermore, the movable base is provided with a positioning through hole, the side wall of the positioning through hole is sunken to form a pivot hole, and the positioning area of the adjusting assembly is provided with a shaft center which is installed in the pivot hole, so that the document stopping area can swing in the positioning through hole. At least one part of the outer edges of two opposite sides of the positioning area of the adjusting component is abutted against the fixed base and the movable base so as to switch the swing angle of the document stopping area. In addition, the file stopping area is asymmetrically arranged relative to the axis of the positioning area, and the rotating shaft of the movable base is vertical to the axis of the adjusting assembly.

Therefore, the adjusting component between the fixed base and the movable base can deflect by rotating the movable base, so that the swing angle of the file stopping area can be switched. At this time, the document stopping area of the adjusting component and a part of the movable base can form the inner edge of the annular track together, or the document stopping area of the adjusting component protrudes into the annular track, so that the water inlet end of the shaft center cannot rotate in the cavity. Because the nozzle structure can output direct water flow or rotary water flow from the same water outlet, the internal flow passage of the nozzle structure can have a simplified structure.

The present application further provides a sprinkler device having a water spraying unit assembled from a mounting base and a housing, the mounting base and the housing defining a chamber. Wherein, the water outlets of the water spraying units for providing direct water flow or rotary water flow are the same; and the adjusting component is arranged in the cavity and can be rotationally switched to form direct water flow or rotary water flow.

The present application further provides a sprinkler device having a water spraying unit assembled from a mounting base and a housing, the mounting base and the housing defining a chamber. The adjusting component is arranged at intervals relative to the shell and the mounting seat so as to stop or form an annular track at the water inlet end of an axis in the cavity.

The nozzle structure is composed of a housing 15, a shaft center 20, a fixed base 40, a movable base 50 and an adjusting component 60. The casing 15 is generally tubular, the front end of the casing 15 is engaged with the inner wall of the adjusting seat 10, so that the casing 15 can rotate synchronously with the adjusting seat 10, the front opening of the casing 15 is positioned at the water outlet 101, and the rear end of the casing 15 is connected to the mounting seat 11, so that the casing 15 can be driven by the adjusting seat 10 to rotate relative to the mounting seat 11. In addition, the mounting base 11 and the housing 15 together define a cavity 17 for accommodating the shaft 20, the fixed base 40 and the movable base 50.

The fixed base 40 has a ring base 41, a central base 45 and the ring base 41 are arranged at intervals, and a plurality of flow deflectors 43 are connected with the ring base 41 and the central base 45. The fixing base 40 further has a plurality of tooth portions 47 protruding from the annular base 41 toward the water inlet 102 to be positioned at the positioning member 12 (shown in fig. 5) of the mounting seat 11, so that the fixing base 40 is spaced apart from the water inlet 102 of the mounting seat 11. The outer annular wall of the annular base 41 is concavely provided with an arc-shaped guide groove and defines two

operation areas

421 and 422. The central base 45 of the fixing base 40 forms a circular groove 451. The circular groove 451 has a middle platform 465 protruded from the center of the bottom of the groove; a lower platform 461 is at the same height as the bottom of the middle platform 465; a high platform 462 is at the same height as the top of the intermediate platform 465; and the two sloped surfaces 463 are located between the low platform 461 and the high platform 462, so that the low platform 461, the high platform 462 and the two sloped surfaces 463 form a continuous surface around the circumference of the intermediate platform 465.

The movable base 50 has a ring base 51, the outer ring wall of the ring base 51 has a radial concave guide groove 52, so that the movable base 50 is positioned on a positioning member 16 convexly arranged at the rear opening of the housing 15, therefore, the movable base 50 and the housing 15 can synchronously rotate, when in installation, the rear opening of the housing 15 is also abutted against an outer ring part of the fixed base 40, the positioning member 16 of the housing 15 is matched with one of the two operation areas 421,422 of the arc-shaped guide groove of the fixed base 40, and the fixed base 40 and the movable base 50 are adjacent to the water inlet of the cavity 17. The movable base 50 further has a central base 55 and a ring-shaped base 51 arranged at an interval; and a plurality of guide vanes 53 extend to the annular base 51 along the radial direction of the central base 55, and the guide vanes 53 are respectively tangent to the central base 55 at a predetermined angle, so that the water flow forms a rotational flow when passing through the movable base 50.

The center of the central base 55 of the movable base 50 has a convex column 54 facing the water outlet 101, a positioning structure 57 protruding toward the water inlet 102, and a positioning through hole 56 eccentrically disposed relative to the center of the central base 55 and penetrating through the positioning structure 57. The positioning structure 57 has an outer annular wall 571 corresponding to the inner annular wall of the circular groove 451 of the central base 45 of the fixing base 40, a rectangular groove body 572 recessed from the bottom of the positioning structure 57 and disposed radially along the positioning structure 57, and two pivoting grooves 575 located at the bottom of the positioning structure 57 and disposed at intervals relative to the rectangular groove body 572. In the present embodiment, a ring-shaped track is defined between the protruding pillar 54 of the movable base 50 and the ring-shaped base 51, and a portion of the positioning through hole 56 is formed by recessing the sidewall of the protruding pillar 54. The positioning through hole 56 is communicated with the rectangular groove 572, so that the groove bottom of the rectangular groove 572 is formed asymmetrically and the blocking surfaces 573,574 (shown in fig. 5) are formed at intervals, and the axial direction formed by the two pivoting grooves 575 is vertical to the rotating shaft of the movable base 50.

The shaft 20 is tubular, the outlet end of the shaft 20 is connected to the front opening of the housing 15, the outlet end is provided with a plurality of guide members 28 in a protruding manner to be matched with the inner annular wall of the housing 15 in a concave-convex manner, and the inlet end of the shaft 20 is provided with a column 25 in a protruding manner to be located on the annular track of the movable base 50, so that the shaft 20 is arranged eccentrically with respect to the outlet direction (i.e. the shaft 20 inclines backwards and outwards). The water source can flow through the guide plate 43 of the fixed base 40 from the water inlet 102 of the mounting seat 11, and form a rotational flow along the guide plate 53 of the movable base 50, so that the shaft 20 rotates along the circular orbit without rotating, and the water flow enters from the water inlet end of the shaft 20 and is sprayed out from the front opening of the shell 15.

The adjustment assembly 60 is somewhat T-shaped, and has a positioning region 62 and a document stop region 63 protruding from a middle section of one side of the positioning region 62, the other side of the positioning region 62 away from the document stop region 63 has a V-shaped outer edge formed by two side faces 651,652, and two projections 661,662 protruding from the other end of the positioning region 62 toward the circular groove 451. The positioning region 62 also has a raised position in which the positioning axis 61 is adjacent to the outer edge of the V-shape, and the document stop region 63 is asymmetrically disposed with respect to the positioning axis 61 of the positioning region 62. The document stopping area 63 of the adjusting assembly 60 is disposed through the positioning through hole 56, so that the positioning area 62 is located in the rectangular groove 572, the positioning shaft 61 is mounted in the pivoting groove 575, one of the two V-shaped outer edge lateral surfaces 651,652 contacts the middle platform 465 of the fixing base 40, and one of the two protrusions 661,662 contacts the high platform 462 of the fixing base 40. Since the positioning penetration hole 56 is larger than the document stop area 63, the adjustment member 60 can swing along the positioning shaft 61.

Referring to fig. 5 and fig. 6, the housing 15 is shown to drive the adjusting assembly 60 to rotate and swing through the movable base 50 to form a linear water flow or a rotating water flow. In the state shown in fig. 5, the positioning element 16 of the housing 15 is locked in the operating region 422 of the arc-shaped guiding slot, so that the projection 661 of the adjusting assembly 60 is pressed against the high platform 462 of the central base 45. Therefore, the document stopping area 63 is located outside the positioning through hole 56, and the document stopping area 63 is located in the circular track to limit the rotation of the shaft center 20, so that the water outlet 101 provides a direct water flow. At this time, the side 652 of the positioning region 62 of the adjustment assembly 60 contacts the middle platform 465 of the fixed base 40, the protrusion 662 of the positioning region 62 is located at the interval formed by the lower platforms 461, one side of the positioning region 62 on the same side as the document stopping region 63 abuts against the stop surface 574 of the positioning structure 57 of the movable base 50, in other words, two ends of the positioning region 62 centered on the positioning shaft 61 abut against the fixed base 40 and the movable base 50 on opposite sides, respectively, so that the adjustment assembly 60 stops swinging.

When the positioning element 16 of the housing 15 is switched from the operation area 422 to the operation area 421, the protrusion 661 of the adjusting assembly 60 slides down to the interval formed by the lower platform 461 along the inclined surface 463 of the central base 45, and the protrusion 662 of the adjusting assembly 60 rises to the upper platform 462, thereby forming the state shown in fig. 6. Therefore, the document stopping area 63 swings towards the inner side of the positioning through hole 56, so that the inner side surface 642 of the document stopping area 63 enters the concave side wall of the convex column 54, and the outer surface of the convex column 54 and the outer side surface 641 of the document stopping area 63 form an inner annular surface of an annular track together, so that the shaft center 20 can rotate in the cavity 17, and a rotating water flow is provided at the water outlet 101. At this time, the side face 651 of the positioning region 62 of the adjustment unit 60 contacts the intermediate platform 465 of the fixed base 40, the projection 661 of the positioning region 62 is positioned at the interval formed by the lower platforms 461, and the side face of the positioning region 62 on the same side as the document stop region 63 abuts against the stopper face 573 of the positioning structure 57 of the movable base 50, so that the adjustment unit 60 stops swinging.

In this embodiment, the adjusting component 60 is completely located inside the housing 15 and the mounting seat 11, and the relative rotation between the fixed base 40 and the movable base 50 enables the adjusting component 60 to swing, so that the document stopping area 63 of the adjusting component 60 stops documents or forms a circular track at the water inlet end of the shaft center 20, therefore, a water source flowing through the water spraying unit 100 can selectively provide direct water flow or rotary water flow through the same water outlet 101, and the internal flow channel of the nozzle structure can have a simplified structure.

In this embodiment, the plurality of guiding elements 28 at the water outlet end of the shaft 20 are positioned in the plurality of grooves of the housing 15, so that the shaft 20 does not rotate, and generates a linear rotating water flow at the water outlet 101. However, the water outlet end of the shaft 20 may only abut against the water outlet 101, so that the shaft 20 rotates to generate a conical water flow at the water outlet 101.

In the present embodiment, the document stopping region 63 of the adjusting assembly 60 has an outer side surface 641 and an inner side surface 642 respectively positioned at the inner side and the outer side of the positioning through hole 56, a side surface of the positioning region 62 on the same side as the document stopping region 63 is respectively positioned at the blocking surface 573,574 of the rectangular groove 572, one of the V-shaped outer edge two side surfaces 651,652 of the positioning region 62 positions the middle platform 465 of the fixing base 40, and the protrusions 661,662 at the two ends of the positioning region 62 are respectively positioned at the high platform 462 of the central base 45, thereby stopping the swinging of the adjusting assembly 60. However, in other embodiments, two of the four positions may be selected to counteract the rotation moment of the adjusting assembly 60, so that the document stopping area 63 of the adjusting assembly 60 stops the document or forms a circular track at the water inlet end of the shaft 20, and the high platform 462 and the middle platform 465 may be located at different heights.

In other embodiments, the movable base 50 is not provided with the protruding pillar 54, the positioning through hole 56 extends axially from the axis of the central base 55 of the movable base 50, the positioning region 62 of the adjusting assembly 60 is pivotally connected to the positioning structure 57, and the document stopping region 63 passes through the positioning through hole 56 and can swing along the positioning through hole 56, so that the document stopping region 63 itself forms an inner ring surface of the circular track or is located in the circular track.

The above-described embodiments and/or implementations are only illustrative of the preferred embodiments and/or implementations for implementing the technology of the present application, and are not intended to limit the implementations of the technology of the present application in any way, and those skilled in the art can make many changes or modifications to the equivalent embodiments without departing from the scope of the technology disclosed in the present application, but should still be considered as the technology or implementations substantially the same as the present application.
