Gear typed sprinkler assembly
First Claim
1. A sprinkler assembly comprising:
- a body havinga holding chamber defined in the body; and
a connecting plug formed on one end of the body and having an inlet;
a base assembly mounted in the holding chamber of the body and comprisinga lower base havinga top;
a bottom;
a wheel chamber formed in the bottom; and
a water entrance formed in the bottom and communicating with the wheel chamber via a passage; and
an upper base being hollow, formed on and protruding from the top of the lower base and having a bottom segment separated from the top of the lower base to define a gap between the bottom segment of the upper base and the top of the lower base and communicating with the wheel chamber in the lower base;
a wheel rotatably mounted in the wheel chamber in the lower base and havinga driving gear mounted through the top of the top of the lower base and held in the gap between the lower and upper bases; and
multiple blades formed around the driving gear and each blade having a free end corresponding to the passage;
a gear assembly comprising multiple gear sets engaging each other, each gear set comprising a driving gear and a driven gear coaxially mounted on the driving gear and having a number of teeth different from that of the driving gear, wherein the driving gear of one of the gear set engages the driving gear on the wheel;
a discharging valve mounted on the base assembly and havinga valve board mounted on the base assembly; and
at least one discharging hole defined through the valve board;
a spraying head being hollow, coaxially connected rotatably to the discharging valve and havinga bottom;
multiple spraying holes defined in the spraying head at positions away from the bottom of the spraying head;
a driven gear mounted around the bottom of the spraying head and engaging the driven gear of one of the gear sets of the gear assembly; and
at least one aligning hole defined through the bottom of the spraying head and selectively aligning respectively with the at least one discharging hole in the discharging valve; and
a cover mounted on the body and having a through hole defined through the cover and through which the spraying head extends out.

Abstract
A sprinkler assembly has a body, a base assembly, a wheel, a gear assembly, a discharging valve, a spraying head and a cover. The wheel is rotatably mounted in a wheel chamber in the base assembly and has a driving gear. The gear assembly has gear sets engaging each other. Each gear set has a driving gear and a driven gear coaxially mounted on the driving gear. The driving gear has a number of teeth different from that of the driving gear. The driving gear of one of the gear set engages the driving gear on the wheel. The discharging valve has at least one discharging hole. The spraying head is coaxially connected rotatably to the discharging valve and has at least one aligning hole selectively aligns respectively with the at least one discharging hole in the discharging valve.
