Abstract
Description
1. Purpose of the invention
[0001] The invention serves the efficient, hygienic, and multifunctional cleaning of toilet bowls and adjacent sanitary surfaces. Through the combination of integrated anti-limescale liquid dosing, two separate water flow channels, a standardized shower connection, and water-fed brush channels, the device enables both classic brush operation and a water-assisted high-pressure cleaning mode. 2. Technical problem
[0002] Conventional toilet brushes offer neither an integrated dispenser for cleaning fluids nor a way to direct water precisely through the brush structure. This creates several problems: • insufficient cleaning effect on stubborn deposits, • lack of option to combine water and cleaning agent, • unhygienic residues on brush fibers, • no option for water-assisted deep cleaning, • No separation between water and chemical flow, which can lead to mixing and backflow problems.
[0003] The invention solves these problems through a modular, hydraulically separated system. 3. Solution approach of the invention
[0004] The invention comprises a toilet brush with: • integrated liquid reservoir and piston pump, • two separate water flow channels, • a shower connection (G1 / 2 standard), • water-carrying brush channels (brushes as flexible or semi-rigid tubes), • separate outlet openings for cleaning fluid, • Check valves to prevent backflow, • Optional round or oval brush head geometry. 3.1 Mechanical Module • Piston pump for dosing the cleaning fluid. • Liquid reservoir in the handle or brush head. • Check valve between liquid channel and water system. • Brush head with integrated mixing chamber and separate outlet zones. • Brush channels as water-carrying mini-pipes. • Perforation ring for chemical outlet openings. 3.2 Electrical module (optional and potentially integrable)
[0005] An electrical module is not included in the basic embodiment of the invention. The invention operates primarily mechanically and hydraulically. However, it is technically possible and provided for in further embodiments to integrate an optional electrical add-on module, for example, for generating vibrations, pulsating water pressure, automatic self-cleaning, or for displaying the fill level of the liquid container. 4. Functionality and advantages • Three operating modes: • Cleaning fluid only (classic brush operation), ◯ Water operation via shower connection (water-carrying brush channels), ◯ Combined operation: water + anti-limescale liquid. • Hygienic self-cleaning: Water rinses the brush channels during operation. • Targeted dosing: Liquid is only dispensed when the piston is actuated. • No mixing: Water and chemical channels remain completely separate. • Increased cleaning performance: Water jets from the brush channels loosen dirt directly at the contact surface. • Ergonomic use: One device replaces several cleaning tools. 5. Compatibility with standard products • Compatible with all standard shower hoses (G1 / 2 thread). • Compatible with all common toilet cleaning fluids. • Brush head compatible with standard toilet brush holders (optional). • Liquid container refillable with commercially available anti-limescale agents. 6. Summary of the advantages • Multifunctional 3-in-1 cleaning device. • Significantly higher cleaning performance than conventional toilet brushes. • More hygienic due to the permanent flushing of the brush channels. • Precise dosing of cleaning agents. • No backflow problems thanks to check valves. • Suitable for toilet bowls, edges, joints and adjacent surfaces. • Reduced chemical consumption through targeted application. 7. State of the art and comparison
[0006] The current market offers: • classic toilet brushes without liquid dispensing, • Brushes with separate cleaning agent containers (without water flow), • Shower attachments for general cleaning (without brush function), • Kitchen sponges with soap dispenser (without water connection).
[0007] None of these products combines water channels, chemical channels, and brushes in one device. 8. Comparison to the state of the art / today
[0008] In contrast to existing solutions, the invention offers: • active water-carrying brush channels, • Separate hydraulic systems for water and chemicals, • integrated shower connection directly in the brush head, • three clearly separated operating modes, • Mixing process only takes place on the cleaning surface, not inside the device. • This represents a significant technological advancement. 9. Degree of innovation
[0009] The invention combines several previously uncombined functions: • Toilet brush + high-pressure water cleaning + liquid dosing. • Water-carrying brush channels as active cleaning nozzles. • Completely separate media routing (water / chemicals). • Modular head geometry (round or oval).
[0010] This combination is novel, technically not obvious, and has high utility model and patent value. 10. Ergonomic and sustainable features • Reduced chemical consumption through precise dosing. • Longer service life thanks to flushable brush channels. • Ergonomic handle with integrated pump. • One device replaces several cleaning tools → less plastic waste. • Optionally replaceable brush heads for sustainable use.
