Water flow switching mechanism of a gear-type sprinkler
First Claim
1. A water flow switching mechanism of a gear-type sprinkler, said gear-type sprinkler comprising a water inlet portion, a water outlet portion and an accommodating space, said water outlet portion having two water outlets linked thereto at an upper wall of said accommodating space, said accommodating space having a change gear set, said water flow switching mechanism comprising:
- a rotary switching seat, mounted into said accommodating space;
a push rod, mounted on a lower wall of said accommodating space;
a coupling member, wherein said rotary switching seat switches opening and closing of said two water outlets, said coupling member being mounted between said push rod and said rotary switching seat; and
a convex framework being assembled onto said accommodating space opposite to said two water outlets, said convex framework having two lateral grooves defined thereon and corresponding to said two water outlets, said rotary switching seat having a pivotal portion assembled centrally into said convex framework, said rotary switching seat having a cylinder shape and two opposite extension flanges defined thereon, the extension flanges blocking a lateral groove in line with a swinging direction of said rotary switching seat.

Abstract
The present invention provides an improved water flow switching mechanism of a gear-type sprinkler, which addresses problems of typical gear-type sprinklers, such as invalid water switching and poor stability. The gear-type sprinkler includes a water inlet portion, a water outlet portion and accommodating space. A convex framework is additionally placed onto the accommodating space opposite the separate water outlets. Two lateral grooves are defined in the convex framework, each corresponding to a water outlet. So the pivotal portion of the rotary switching seat is assembled centrally into the convex framework. The rotary switching seat is provided with two opposite extension flanges. The extension flange may block the lateral groove of the convex framework in line with the swinging direction of the rotary switching seat. The water-stop area of rotary switching seat is greatly increased, thus ensuring the stability of the water flow switching state and improving performance of the sprinkler.
