Multifunctional cleaning device with sponge and brush surface, integrated liquid dispenser, rubber squeegee and shower connection for shower cubicles, tiles and sanitary surfaces

Abstract

Multifunctional cleaning device for sanitary surfaces with a housing that includes a sponge surface, a brush surface and a rubber squeegee, an integrated liquid container with manually operated dosing mechanism, a shower connection for connection to a shower hose and internal, separate water and chemical channels, whereby water is directed to the cleaning surfaces via the water channels and cleaning agent is dosed exclusively via the chemical channels.

Description

1. Purpose of the invention

[0001] The invention serves for the complete wet cleaning of shower cubicles, tiles, bathtubs and other sanitary surfaces by combining a sponge, brush, squeegee, water supply and cleaning agent dosing in a single handheld device. This enables efficient, ergonomic cleaning with reduced chemical use. 2. Technical problem

[0002] The current state of the art does not offer a compact solution that: • Directs water directly from a shower hose through a sponge or brush, • Cleaning agents precisely dosed, • Sponge, brush and rubber wiper combined in one device, • Automatically clears blockages in the outlet openings, • enables one-handed operation, • Media lines (water / soap) are hygienically separated.

[0003] This makes cleaning time-consuming, inefficient, and requires several separate tools. 3. Technical field

[0004] The invention belongs to the field of sanitary and household cleaning, in particular to hand-held cleaning devices with integrated water supply and cleaning agent dosing. 4. Object of the invention

[0005] The task is to provide a multifunctional cleaning device that: • Sponge, brush and rubber squeegee combined, • Keep water and cleaning agents separate, • can be connected directly to a shower hose, • Clears blockages independently, • enables the entire cleaning process to be completed in one step. 5. Solution to the task

[0006] The task is solved by a device with: • a shower connection (G1 / 2), • internal water channels, • a sponge surface with water and / or soap distribution, • a brush surface with water-carrying outlet openings, • an integrated liquid container with dosing mechanism, • a rubber squeegee for streak-free removal, • separate channels for water and cleaning agents, • a self-cleaning mechanism to remove blockages. 6. Solution approach of the invention

[0007] The core of the invention is the complete separation of media routing: • Water is channeled to the sponge or brush via internal channels. • Cleaning agent is dosed via a separate channel. • Media mix only on the surface, not inside the device. • A rubber squeegee allows for final drying. • A pressure flushing mechanism automatically clears blockages.

[0008] This creates a 3-in-1 cleaning system. 7. Components 7.1 Mechanical Module • Housing with three cleaning surfaces (sponge, brush, rubber wiper) • Shower connection (G1 / 2) • Internal water channels • Liquid container • Manual dosing pump (piston, push button or diaphragm) • Check valve • Water outlet openings • Outlet openings for cleaning agents • Self-cleaning mechanism (pressure flushing) • Optionally interchangeable sponge and brush modules 7.2 Electrical module (optional)

[0009] Optionally integrable: • Vibration motor for cleaning assistance • Electric micropump for cleaning agents • LED level indicator • Pulse valve for pulsating water jet

[0010] The basic version works without electronics. 8. Functionality and advantages • Water flows directly through the sponge or brush. • Cleaning agent is dosed precisely. • Sponge for gentle cleaning, brush for stubborn dirt. • Rubber squeegee for streak-free removal. • Three operating modes: water, soap or combination. • Self-cleaning automatically clears blockages. • One device replaces several cleaning tools. • Ideal for vertical surfaces (shower cubicles, glass, tiles). 9. Compatibility with standard products • Compatible with all standard shower hoses (G1 / 2). • Compatible with all common cleaning agents. • Sponge, brush and rubber wiper are replaceable. • No special connections required. 10. Summary of the advantages • Multifunctionality (sponge + brush + rubber squeegee + water + soap) • High cleaning performance • Low chemical consumption • Hygienic media management • Easy one-handed operation • Compatible with standard shower systems • Sustainable thanks to interchangeable modules 11. State of the art and comparison

[0011] The market offers: • Sponges without water channels • Brushes without soap dispensers • Shower attachments without cleaning surfaces • Devices without separate media channels • Rubber wiper as a separate tool

[0012] None of these products combines all functions in one device. 12. Comparison to the state of the art

[0013] The invention offers: • separate water and chemical channels, • integrated soap dispenser • three cleaning surfaces, • direct shower connection, • Self-cleaning in case of blockage, • three operating modes, • Complete cleaning in one step. 13. Degree of innovation

[0014] The combination of sponge, brush, rubber squeegee, water flow, soap dispenser and self-cleaning is novel and not technically obvious.

[0015] The invention represents a new product category in the field of sanitary cleaning. 14. Ergonomic and sustainable features • One-handed operation • Reduced chemical consumption • Interchangeable cleaning modules • Long-lasting thanks to self-cleaning • Less plastic waste thanks to modular construction

Claims

Multifunctional cleaning device for sanitary surfaces with a housing that includes a sponge surface, a brush surface and a rubber squeegee, an integrated liquid container with manually operated dosing mechanism, a shower connection for connection to a shower hose and internal, separate water and chemical channels, whereby water is directed to the cleaning surfaces via the water channels and cleaning agent is dosed exclusively via the chemical channels. Cleaning device according to claim 1, characterized in that the sponge surface is designed to be water-permeable and the water flow is directed directly through the sponge onto the surface to be cleaned. Cleaning device according to one of the preceding claims, characterized in that the brush surface has water-carrying outlet openings through which water escapes during operation to enable a combined scrubbing and rinsing function. Cleaning device according to one of the preceding claims, characterized in that the integrated liquid container doses cleaning agent via a piston, push button or membrane mechanism, which is dispensed either into the sponge or directly onto the cleaning surface. Cleaning device according to one of the preceding claims, characterized in that the shower connection is designed as a G1 / 2 standard thread and is compatible with commercially available shower hoses. Cleaning device according to one of the preceding claims, characterized in that a check valve is provided which prevents the backflow of water into the liquid container. Cleaning device according to one of the preceding claims, characterized in that an integrated self-cleaning mechanism is provided which, in the event of increased water pressure or repeated actuation of the dosing mechanism, causes an automatic flushing of the water and chemical outlet openings, so that deposits or blockages are automatically loosened and flushed out. Cleaning device according to one of the preceding claims, characterized in that the rubber wiper is arranged on an edge of the housing and serves to remove water from glass and tile surfaces without streaks. Cleaning device according to one of the preceding claims, characterized in that the rubber wiper can optionally be moistened via the internal water guide to increase the gliding ability on smooth surfaces. Cleaning device according to one of the preceding claims, characterized in that three operating modes are possible, in which either only water, only cleaning agent or a combination of water and cleaning agent is used.
