Definitions

  • the present invention relates to a replacement toilet brush according to the independent claim.
  • Toilet brushes typically have a short handle with a handle and a head that extends across the handle.
  • the thicker head which extends transversely to the direction of the stem, is equipped with bristles or shapes with which buildup can be removed in a toilet.
  • the DE 20 2005 011 730 U1 suggests the use of bristle-free brush heads, in which shaped soft edges should enable cleaning.
  • the problem can arise that the edge lies flat, as a result of which the pressure is evenly distributed and stubborn build-up cannot be removed.
  • the present invention is located in the field of toilet brushes and brush heads, in which bristles with small, punctiform supports are used for cleaning.
  • a cleaning brush which can be produced entirely as an injection molded part.
  • the bristles with molded form comprise at least two groups, the two groups with clearly different spatial shapes two Allow specific cleaning modes.
  • the bristles are each arranged in a common area and aligned as a parallel family on one area. This effectively suppresses noises during use, which are particularly embarrassing for Japanese culture.
  • the disadvantage here is that the very different spatial shapes and flat arrangement of the bristles require different bristle stabilities. An early, mechanical failure of at least one of the spatial shapes is likely.
  • Another disadvantage is that a spatial shape is proposed here that deviates greatly from the usual bell shape. An atypical spatial shape requires an individual holder and makes it impossible to use such a brush as a replacement brush, especially in the European area.
  • Generic replacement toilet brushes with a brush head include in the brush head a base body with a receptacle for a brush handle and with plastic bristles protruding from the base body. Generic toilet brushes thus have such a brush head.
  • the brush head has an essentially bell-shaped spatial shape, with the bristles reaching downwards towards a hemispherical to elliptical outer boundary when the brush is held vertically downwards, in order to change upwards into a cylindrical to slightly expanding spatial shape.
  • the shape of the room resembles a bell standing upside down when the brush is held vertically downwards.
  • receptacles set up or attached close to the toilet, which offer a cylindrical hollow shape with a hemispherical bottom, into which the brush head can be inserted with slight clamping tension. Additional bristle or stem formations, as in the DE 200 18 712 U1 or the DE 202 02 910 U1 be proposed, allow the additional cleaning of the toilet rim.
  • a household cleaning brush is known, which is improved in the cleaning properties.
  • Elastomer-based brushes and Initially, bristles are rated as too soft and too flexible.
  • the head of the brush can have the roughly bell-shaped spatial shape described above.
  • the rounded bristles are an integral part of the head, the brush head is therefore in one piece.
  • the cross-sectional shape of the bristles is assessed as technically irrelevant and only limited due to the process. It is essential that the plastic bristles are formed in bundles by injection molding. The greater density of the sprayed bristles enables the improved cleaning effect to be achieved.
  • bristle bundles tend to adhere to the bundle under clamping tension, as a result of which such a brush quickly becomes dirty and unsightly.
  • a generic brush head made of rubber which has molded rubber bristles.
  • the advantage of the rubber head is a significantly increased durability, since the bristles can no longer break off or break out of the base body.
  • a disadvantage of the bristles made of white plastic in the usual way is that even with laboriously rinsed dirt from the brush head, an unsightly, yellow limescale is quickly visible on the base body and on the bristles.
  • white plastic bristles tend to fix dirt and residues in the dense bundles of bristles.
  • Another disadvantage is that elastomer-based bristles are often too soft and too flexible to be able to effectively remove buildup in the frictional connection.
  • the object of the present invention was therefore to overcome the disadvantages of the prior art and to provide a brush head which, despite an increased durability and a longer acceptable appearance, can provide adequate cleaning performance.
  • a toilet brush which is not further claimed, has a brush head and a brush handle, the brush head having an essentially bell-shaped spatial shape.
  • the brush head of a toilet brush comprising a base body with a receptacle for a brush handle and with plastic bristles protruding from the base body, is characterized in that the bristles are made of TPE-V.
  • the olefin base of such polymers as a hydrophobic, waxy compound class can provide improved hydrophobicity in relation to the aqueous and water-soluble contaminants. This can explain why the low wettability with residues and or buildup was surprisingly good.
  • the brush head which is not claimed, is characterized in that the bristles, projecting individually, have a conically tapering spatial shape with a blunt tip and that the bristles have a thickness over the entire bristle length in the millimeter range.
  • the bristles projecting individually, have a conically tapering spatial shape with a blunt tip and that the bristles have a thickness over the entire bristle length in the millimeter range.
  • tips that are one millimeter thick and have a blunt end, a high system pressure can be created at certain points, with which even stubborn build-up can be removed easily.
  • tip thicknesses beyond 4 millimeters effective pressing proved to be hardly feasible: on the one hand, the bristles were too stiff in groups due to the continuous thickness of 4 millimeters and more, and on the other, they lay too large on the ceramic surface to be cleaned.
  • the brush head which is not claimed, is characterized in that a continuous, one-piece TPE-V body comprises both the base body and the bristles.
  • the brush head which is not claimed, is characterized in that the brush head has an edge cleaner with individually projecting cleaning bristles.
  • 'Edge cleaners' are shapes that allow the cleaning bristles to engage in the underside of a toilet rim. Examples of possible shapes can be found in the prior art. It is preferably proposed in the present case to design an edge cleaner in the form of a hook which is open in a U-shape upwards in the direction of the handle on the side of the base body and to provide cleaning bristles.
  • the edge cleaner with its bristles thus particularly preferably fits into the essentially bell-shaped spatial shape of the brush.
  • a bell-shaped spatial shape which is still present, allows the brush head to be held in the established receptacles according to the prior art.
  • the U-shaped edge cleaner which is open at the top, advantageously allows the edge to be cleaned when the brush is aligned vertically. When the brush / handle is aligned vertically, it is reliably avoided that the opposite edge of the toilet hinders the necessary movement of the handle or cleaning, or could make it impossible.
  • the brush head which is not claimed, is characterized in that the edge cleaner is part of the one-piece TPE-V body. This offers the advantage of increasing the versatility of an existing toilet brush with a replaceable brush head without having to buy a new handle or a new holder.
  • the brush head which is not claimed, is characterized by the fact that the TPE-V is colored gray to dark gray. This offers the advantage that even with extremely hard water with a high lime content, no unsightly gray haze is visible due to the inevitable superficial limescale. This advantageous measure thus guarantees a permanently attractive appearance of the brush head even under the most adverse conditions.
  • the toilet brush which is not claimed, has a brush head, the brush head having an essentially bell-shaped spatial shape.
  • the latter advantageously allows the toilet brush to be held in established holders and receptacles.
  • the toilet brush which is not claimed, is characterized in that it has a brush handle made of stainless steel.
  • a stainless steel handle fits almost all furnishings in the domestic sanitary area and advantageously ensures a harmonious overall picture of an interior.
  • the replacement toilet brush is advantageously compatible with the established holders, offers the additional function of an edge cleaner and provides a harmonious appearance of the brush head for a significantly longer period of time, which means that the product is accepted longer by the user.
  • the present invention claims a replacement toilet brush with a brush head.
  • the problem of unsightly buildup on the brush heads of conventional toilet brushes is improved according to claim 1. This is done by using a TPE-V material, which is colored gray to dark gray. As a result, a replacement toilet brush is accessible, which offers a visually attractive, clean appearance for longer and more reliably.
