## Abstract

Water flow through the main body and a cover of a cleaner is regulated by a flow guide having an L-shaped flow groove which permits water flow through the cleaner to be selectively terminated or directed through either a straight outlet for direct contact with an object to be cleaned or through a spray outlet of the main body for flow down and around an invertible cleaning block through an annular space formed in the cover.

## Claims

### Claim 1

A cleaner comprising:
a) a main body including a front end, a longitudinal water passageway extending therethrough, a straight outlet in the front end, a guide recess, a spray outlet in a lower wall below the guide recess, an annular contact flange below the spray outlet, and a rear end for engagement with a water supply tube;
b) a flow guide disposed within the guide recess, the flow guide including an L-shaped flow groove on a peripheral surface thereof, the flow guide being rotatable within the guide recess for selective disposition between any one of three different water flow positions, including terminating water flow, permitting water flow through the straight outlet and permitting water flow through the spray outlet;
c) a rectangular-shaped cover including four side walls and an upper wall defining an inner chamber having an open bottom side, the walls each including an outer layer spaced from an inner layer, the spaces between the inner and outer layers collectively defining an inner annular space terminating in a plurality of outlet holes around a lower circumferential edge of the side walls, a threaded annular projection extending from the upper wall for receiving water flow from the main body and directing same through the inner annular space and out the outlet holes;
d) a threaded fixing ring disposed in an engagement with the annular contact flange of the main body and in threaded engagement with the threaded annular projection of the cover for securing the main body to the cover and permitting the cover to be rotated relative to the main body;
e) a cleaning block disposed within the inner chamber of the cover, the block including an engaging member for detachably securing the block to the inner chamber, a brush and a sponge extending from opposite sides of the engaging member and the block being invertible for selectively disposing the brush or the sponge in a downwardly facing position of use; and
f) a constriction ring engageable with the rear end of the main body for securing a water supply tube thereto.

### Claim 2 (depends on 1)

The cleaner of claim 1 wherein the guide recess includes a side wall having a threaded annular projection thereon, the flow guide including a rear end surface having a threaded projection thereon, and the threaded projections of the guide recess and the flow guide being in threaded engagement with each other.
