## Abstract

Toilet flushing systems installed in a toilet reservoir. A toilet reservoir stores a fluid that pours into a toilet bowl for carrying waste away from a toilet. Exemplary toilet flushing systems may include a flush sleeve having a sleeve bottom and sleeve top. The exemplary sleeve bottom may connect to a bottom of the toilet reservoir around a reservoir drain. The flush sleeve may be capable of being raised in a raised orientation such that the sleeve top is above the fluid in the toilet reservoir to prevent the fluid from entering the reservoir drain. Exemplary toilet flushing systems may include a flush sleeve actuator that lowers the sleeve top of the flush sleeve below a fluid level in the toilet reservoir to allow the fluid to flow through the flush sleeve into the reservoir drain.

## Claims

### Claim 1

A toilet flushing system installed in a toilet reservoir, the toilet reservoir for storing a fluid that pours into a toilet bowl for carrying waste away from a toilet, the toilet flushing system comprising:
a flush sleeve having a sleeve bottom and sleeve top, the sleeve bottom connected to a bottom of the toilet reservoir around a reservoir drain, the flush sleeve in a raised orientation when the sleeve top is above the fluid in the toilet reservoir to prevent the fluid from entering the reservoir drain;
a flush sleeve actuator that lowers the sleeve top of the flush sleeve below a fluid level in the toilet reservoir to allow the fluid to flow through the flush sleeve into the reservoir drain; and
a float collar configured around the flush sleeve, the float collar configured to float on the fluid in the toilet reservoir.

### Claim 2 (depends on 1)

The toilet flushing system of claim 1 wherein the flush sleeve actuator further comprises a detent configured on the float collar that slides into a collar slot on the flush sleeve to engage the float collar with the flush sleeve such that the flush sleeve rises with the fluid level on which the float collar floats.

### Claim 3 (depends on 2)

The toilet flushing system of claim 2 wherein a least a portion of the detent is configured from magnetic material.

### Claim 4 (depends on 2)

The toilet flushing system of claim 2 wherein a least a portion of the collar slot is configured from magnetic material.

### Claim 5 (depends on 2)

The toilet flushing system of claim 2 further comprising one or more float rails to guide the float collar vertically inside the toilet reservoir, the one or more float rails positioning the float collar to engage the flush sleeve as the float collar descends with the fluid level in the reservoir tank.

### Claim 6 (depends on 2)

The toilet flushing system of claim 2 wherein the detent is operatively connected to a toilet tank handle such that the detent is removed from the collar slot when the toilet tank handle is operated by a user.
