Sprinkler gear set and sprinkler containing the gear set

Abstract

This invention relates to a gear assembly for a sprinkler, comprising: a plurality of gears and a shaft. The shaft defines an axial direction, along which the plurality of gears pass. The shaft includes at least one abutment portion that abuts against at least one of the gears along the axial direction, thereby providing support to the at least one gear. In this way, when the sprinkler is activated, the force exerted by the water flow along the axial direction on the plurality of gears does not accumulate. The at least one abutment portion helps the abutting gears effectively resist water pressure and prevents the water force from being transmitted from one gear to the next, ensuring that each gear rotates smoothly, reliably, and quickly.

Claims

1. A gear set for a sprinkler, comprising: Complex gears; A shaft is defined with an axial direction along which the plurality of gears are passed, and includes at least one abutment portion that abuts against at least one of the gears in the axial direction, thereby providing support force to at least one of the gears.

2. The gear set of the sprinkler as claimed in claim 1, wherein the shaft further includes a main body, the at least one abutment portion is integrally formed with the main body, and the main body passes through the plurality of gears along the axial direction.

3. The gear set of the sprinkler as claimed in claim 2, wherein the shaft column is further defined in a radial direction, and the body includes a small diameter section and a large diameter section connected coaxially, wherein the small diameter section and the large diameter section form an abutment extending in the radial direction at the connection point.

4. The gear set of the sprinkler as claimed in claim 3, wherein the maximum radial dimension of the abutment portion is defined as a first dimension, the outer diameter of the minor diameter segment is defined as a second dimension, and the ratio of the first dimension to the second dimension is between 0.05 and 0.

30.

5. The gear set of the sprinkler as claimed in claim 1, wherein the at least one abutting portion includes an abutting surface, the normal direction of the abutting surface being equal to the direction of the axial direction, and the abutting surface abutting against the gear.

6. The gear set of the sprinkler as claimed in claim 1, wherein the gear abutting against the at least one abutting portion is defined as a first gear, and another gear not abutting against the at least one abutting portion and adjacent to the first gear is defined as a second gear, the second gear and the first gear are respectively located on opposite sides of the at least one abutting portion, and the first gear and the second gear maintain a distance between them in the axial direction.

7. The gear set of the sprinkler as claimed in claim 4, wherein the at least one abutting portion includes an abutting surface, the normal direction of the abutting surface being equal to the axial direction, the abutting surface abutting against the gear; the gear abutting against the at least one abutting portion is defined as a first gear, and another gear not abutting against the at least one abutting portion but adjacent to the first gear is defined as a second gear, the second gear and the first gear are respectively located on opposite sides of the at least one abutting portion, the first gear and the second gear maintaining a distance between them in the axial direction; the number of at least one abutting portions is one; each gear includes a large gear ring and a small gear ring, the number of teeth of the large gear ring being greater than the number of teeth of the small gear ring, the abutting portion abutting against the side of the large gear ring facing away from the small gear ring; the ratio of the distance between the large gear ring and the first dimension is between 0.1 and 0.

3.

8. A sprinkler system, comprising: One water inlet connector; A main body comprising a movable cylinder and a connecting seat, the movable cylinder and the connecting seat being assembled together to form an internal space, the movable cylinder being rotatably fitted onto a water inlet connector, and the connecting seat having a first water outlet and a second water outlet communicating with the internal space; a plurality of gear sets of a sprinkler as described in any one of claims 1 to 7, meshing with each other and positioned in the internal space, engaging with the water inlet connector; a water flow switching assembly, oscillatingly housed in the internal space, selectively covering one of the first water outlet and the second water outlet; and an impeller, located outside the internal space and assembled on the connecting seat, meshing with the plurality of gear sets to form a linkage relationship, and being driven to rotate by the fluid flowing out of the first water outlet and the second water outlet.

9. The sprinkler as claimed in claim 8, wherein the water flow switching assembly includes a rocker arm, an elastic member, and a stop member, the rocker arm being oscillatingly mounted on the movable cylinder, the rocker arm having a chamber, the stop member being telescopically inserted into the chamber, the elastic member abutting against the inner wall surrounding the chamber and the stop member, the elastic member giving the stop member a tendency to move toward the connecting seat in its normal state, and the stop member selectively covering one of the first water outlet and the second water outlet depending on the swing position of the rocker arm.

10. The sprinkler as claimed in claim 9, wherein the connecting seat is further provided with an abutting protrusion between the first water outlet and the second water outlet, and the stop member includes a first stop portion, a second stop portion, and a locking portion, the locking portion being located between the first stop portion and the second stop portion, a first locking groove being defined between the locking portion and the first stop portion, and a second locking groove being defined between the locking portion and the second stop portion; wherein, When the rocker arm swings and the abutment protrusion is inserted into the first slot, the first stop covers the first water outlet. When the rocker arm swings and the abutment protrusion is inserted into the second slot, the second stop covers the second water outlet. During the swing of the rocker arm, the locking part abuts against the abutment protrusion, forcing the stop to move deeper into the chamber and compress the elastic member until the locking part crosses the abutment protrusion, and the elastic member springs against the stop and moves in the direction of moving out of the chamber. The stop also includes a post, and the elastic member is sleeved on the post. The abutment is facing the water inlet connector. The abutment parts of the plurality of gear sets are located at different horizontal heights.
