Abstract

The hand brush (10) has a grip part (15) constructed as a reservoir (16) for a cleaning liquid. The liquid outlet channel (14), constructed in the bristle bearer (12), can be closed by means of a spring-loaded closure member (20) which has a projection (21) projecting through the liquid outlet channel (14) and into the bristle region, which projection has a shorter length than the bristles (13) both in their position of rest and under their normal load of operating pressure. Only under greater pressure on the hand brush (10) does the projection (21) come into contact with the surface to be cleaned, which leads to the exposure of the liquid outlet channel (14) by raising the closure member (20, 20a). <IMAGE>

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hand-held brush with a handle part configured as a reservoir for cleaning liquid and a bristle holder with at least one liquid outflow channel.

PRIOR ART J It is already known to combine a hand-held brush with a reservoir for cleaning liquid or cleaning paste.

In known hand-held brushes of this kind, the cleaning liquid flows automatically to the bristles from one or more liquid outflow passages, or the cleaning liquid flows through the outflow passages to the bristles area by manual operation of an outflow valve or by tying off. given to. Uncontrolled outflow of cleaning liquid has proven to be a disadvantage. This is because the outflow cannot be controlled and the cleaning liquid is therefore consumed too quickly. The dispensing of the cleaning liquid or the cleaning paste makes it practically necessary to dispense the cleaning action if the desired supply of cleaning agent to the working area has to be achieved. The configuration of a manually controlled valve arrangement also proves to be impractical and also requires a relatively large equipment outlay, which makes hand-held brushes significantly more expensive.

[Problem that the invention seeks to solve]

The object of the invention is to improve a hand-held brush of the type mentioned at the outset, so that the hand-held brush can be applied to the bristle range of the hand-held brush in a simple manner and by simple structural measures without having to interrupt the cleaning process. The purpose is to allow arbitrary control of the cleaning liquid supply.

[Means for solving problems]

According to the invention, this object is achieved in that the liquid outflow channel has a movable closing element, which closing element has a projection projecting into the bristle area of the hand brush, and the closing element projection projects from the liquid outflow path into the bristle area. This is solved by the part having a smaller length than the bristles in the inactive position and when subjected to normal operating pressures. This means that work can be done at normal operating pressures with a hand brush constructed according to the invention without liquid being discharged from the hand brush reservoir. Only if the bristles of the bristle holder are bent more strongly than usual due to the increased pressure on the hand brush, can the closure member projections strike the surface to be cleaned and thereby open the liquid outflow channel for the release of cleaning liquid. can be opened by opening the closing member.

The part of the closure member projection which projects into the bristle region is preferably made of a non-stick, soft material and consists of short bristles or even shorter bristle bundles, so that the object to be cleaned can be washed by the closure member projection. Increased pressure can be applied to the hand-held brush while the cleaning process continues without the risk of being scratched.

In the hand-held brush constructed according to the present invention, at least a portion of the wall of the grip portion can be constructed to be flexible, so that when applying an increased pressing force to the bristles, the volume of the cleaning liquid reservoir and space can be reduced. Pressure is exerted on the grip part with a tendency to cause the cleaning liquid to be squeezed out by the opened closure member and to obviate the need for a separate air supply of the reservoir space or to facilitate forced ventilation via the liquid outflow channel. become.

A hand-held brush constructed in accordance with the present invention can be manufactured inexpensively from a small number of individual parts. Preferably, the grip part of the hand-held brush can end in a filling opening that is closable by a screw cap.

Advantageously, the closure member can consist of a simple elastic cap or a splash-loaded closure plate with a pin-like projection projecting into the liquid outflow channel at a distance from the wall of this liquid outflow channel. . In this case, the closure member projection that projects into and beyond the liquid outflow channel is simultaneously able to automatically clean the outflow channel and to clean the drying part by the movements that this N5 chain member projection undergoes during operation. Ensures removal of agent residues.

〔Example〕

Embodiments of the subject matter of the invention will be described in detail below with reference to the accompanying drawings.

The hand-held brush lO, which is constructed rotationally symmetrically with respect to the axis 11, has a circular bristle holder 12 or 12a, which is provided with a bristle bundle 13 on its outer surface and has a central passage opening 14. The central passageway forms a liquid outflow passage. A rotationally symmetrical hollow handle part 15 is connected to the bristle holder 12 , the interior space of which forms a reservoir 16 for the cleaning liquid;
A cleaning liquid can be injected through the upper opening 17 of. The upper part Q17 of the gripping part 15 is internally threaded 18 and can be closed by a rounded threaded cap 19 for better gripping.

The passage opening 14 forming the liquid outflow channel of the bristle holder 12 in the embodiment according to FIGS.
It can be closed on the inside by a plate-shaped closing member 20, which has a bottle-shaped projection d 21 which projects outwardly through the passage opening 14.

The bottle-shaped protrusion 21 is made of a soft, non-stick material and can have longitudinal grooves.

The part of this projection which projects into the area of the bristles 13 is much shorter than the length of the bristles I3 in the inactive position shown in the drawing. A disk spring 22 rests on the closing member 20 and is supported in the edge region on an inner step 23 of the handle part 15 . The disk spring 22 can be constructed as a simple spiral spring with a passage opening (not shown) or can be stored in a spring tab which is supported at both ends on the inner surface of the handle part 15. According to the embodiment of FIG. 3, the closing member 20a itself can be constructed as a spring rocker plate which is attached to the bristle holder 12a by means of studs or screws 24.

Closing element 20 or 20 projecting into the area of the bristles 13
The length of the protrusion 21 of a is selected such that, even under normal operating pressures and even if bending of the bristles 13 occurs, this protrusion still does not come into contact with the surface to be cleaned. . Only by increasing the pressing force on the hand-held brush by the hand operating the hand-held brush during operation with the hand-held brush does the protrusion hit the surface to be cleaned and the liquid outflow channel 14 due to the rM'IR of the closure member 20 or 20a
The number of M is reached. Walls and protrusions 21 of liquid outflow passage 14
Alternatively, the distance between the protrusion 21 and the longitudinal groove is selected to be such that the cleaning liquid can flow out and air can flow in through the open liquid outflow passage, depending on the concentration of the cleaning liquid. The wall of the gripping part 15 can be constructed flexibly in places, so that when increasing the pressure on the hand-held brush, no pressure is exerted on the cleaning liquid introduced into the reservoir space 16. This pressing force facilitates the outflow of the cleaning liquid. However, the reservoir space 16 can also be vented by means of a known rocking valve (not shown) in the screw cap 19, which allows the cleaning liquid to flow out when the hand brush 10 is tilted. Prevent spills.
