Cleaning device with a brush connected to a fluid supply.

The invention relates to a cleaning device for cleaning surfaces such as vehicle bodies, painted surfaces, walls, windows, agricultural and dairy equipment or the like. The invention relates to in particular a cleaning device with a hand-operated brush with a hollow handle through which

when the brush is used, liquid can be continuously fed to the bristles.

In the usual form of a hydrated brush, such as that used for washing cars is, the hollow stem is provided with a connector, which is connected to a hose a tap can be connected. Here, a cleaning liquid is usually used manufactured either by solid tablets that can be inserted into the hollow brush handle, or by passing the supplied water through a separate mixer leads with such tablets or with a liquid cleaning agent is filled.

In many cases, however, a hose is not available and / or a faucet is not available close enough to the vehicle or the surface to be washed, and also if a user of the cleaning device has a Has hose available, he is often bothered to roll it up at the tap to connect and then to roll up again, discouraged from use.

On the basis of such considerations, brushes for car washing have already been produced that only come in one Buckets of water or a cleaning solution need to be submerged long enough to keep the liquid in place fills the cavity of the handle, from which it then slowly with the subsequent use of the brush the brush escapes through narrow openings in the bristle base.

With a more complex device that eliminates the need for frequent immersion of the brush to be avoided in a liquid container is a narrow hose to the connector of the Brush connected and provided at its free end with a rubber flap valve, which is when Use of the brush by bending and stretching the hose automatically closes and opens, so that when the valve is immersed in liquid, the liquid eventually fills the tube and then comes out of the brush in bursts.

Another well-known device, which is in the. use has proven better than the one mentioned above, but has its own obvious drawbacks, works with gravity feed or siphon-like feeding of the liquid to the brush through a

909829/1138

narrow hose, the free end of which dips into a bucket or other open container, which is higher as the brush is arranged (ex the roof of a car to be washed).

The object of the present invention is a simple and reliable way to ' Operating a brush with liquid supply "to create that has no connection to a water supply network and does not require an elevated liquid container,

According to the invention, a cleaning device is provided with a hand-operated brush a liquid supply to the bristles which can be connected to a liquid source, characterized in that a connecting piece to the A brush connecting to a container of liquid narrow tube is fitted with a hand-squeezable flexible extension that extends between Check valves are arranged such that an alternating squeezing and releasing the enlargement causes an intermittent supply of fluid to the brush. ■.

The free end of the hose can be provided with a relatively heavy inlet piece, which rests on the bottom of the liquid container. Another advantageous option consists in the fact that such an inlet piece (or the part of the hose connected to it) with a hook or split ring is provided, which is hooked into the handle of the bucket used as a reservoir can be.

One embodiment of the invention is shown in Drawings shown.

The outer end of the line 9 is widened at 11 and provided with a thread, which receives the correspondingly formed end of a handle 12 made of rubber or plastic, a sealing ring I ^ being inserted between the handle and the brush body. An axial channel 14- is formed in the handle 12. The end of the handle is designed with sawtooth-shaped annular ribs 15 and cooperates with a rubber-shaped connector 16 at the end of a plastic tube VJ , which is for example two and a half meters long. -

At the other end of this hose is a hollow inlet piece 18 made of rubber or other material

At a suitable distance (e.g. 1 m) from the connector 16 away is the hose 17 in

divided into two sections. Between these off %

cut is a slightly compressible rubber bladder 2o inserted with two opposing pins 21, which are connected to the adjacent hose sections via check valves 22, 2 ^, both connection points are covered by rubber hose pieces 2k. '

As can be seen from Fig. 2, there is each valve

advantageously from a tubular metal housing A.

25, in which a valve cone 26 is held captive, the head of which has a valve seat at one end *. of the housing cooperates. The housing is fastened in the corresponding lug 21 of the rubber bladder by a wire 27 bent around it.

The valve units 22, 25 are the same Sense of flow arranged so that the valve 22 only the entry of liquid into the rubber bubble 2o allowed, while the other valve 25 only, the Leakage of liquid from the rubber bladder-enables »

The first time you squeeze the bladder, the the air inside is pressed through the outlet valve 2> in the direction of the brush .5, and an enti speaking volume of liquid is in the lower part of the hose If through an inlet piece 18, provided sieve 28 sucked. This process repeats itself until the liquid over the inlet valve 22 enters the bladder and finally with each compression of the bladder 2o a quantity of liquid through the brush cavity Io the bristles 7 er ~ enough.
