Surface Cleaning Head Jet Nozzle Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning heads are difficult to handle and prone to malfunctions due to external connections and exposed components, which increase the risk of damage and complicate the suction process.
Innovation Solution
The surface cleaning head integrates the jet nozzle into the housing, using a single feed line for both cleaning nozzles and the jet nozzle, and incorporates a distributor with internal branch lines for efficient liquid supply, allowing for a compact design and improved suction efficiency by reducing the distance between the jet nozzle and the surface, and optionally includes a detachable suction nozzle for enhanced suction capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the jet nozzle and cleaning nozzles are supplied via separate external lines, then the cleaning head can be supplied with cleaning fluid, but the handling becomes more difficult and the risk of mechanical damage increases
Solution Approach 1:
The patent combines the supply lines for the jet nozzle and cleaning nozzles into a single integrated line system. The high-pressure cleaning device supplies cleaning fluid through one main line that branches internally within the cleaning head housing to reach both the jet nozzle and cleaning nozzles, eliminating the need for multiple external connections and reducing mechanical damage risks.
Solution Approach 2:
The patent nests the jet nozzle and cleaning nozzles within the housing structure, with supply lines routed internally through the housing rather than externally. This nesting arrangement protects the lines from mechanical damage and simplifies the external appearance, leaving only a single connection point visible.
2Reliability
If the jet nozzle is positioned outside the housing, then it can be supplied with cleaning fluid, but the distance to the surface increases reducing suction effectiveness
Solution Approach 1:
The patent merges the positioning of the jet nozzle and cleaning nozzles within the same housing structure, allowing both to be positioned close to the surface simultaneously. The integrated design enables the jet nozzle to operate at optimal distance for suction while the cleaning nozzles apply fluid at the same location.

Function Achieved in This Case
This design simplifies handling, reduces the risk of mechanical damage, enhances suction effectiveness, and improves cleaning results by ensuring a consistent and powerful suction flow, while allowing for optional detachment of the suction nozzle when not needed.
Implementation Method 1
a jet pump for extracting fluid applied to the surface, wherein the jet pump has a jet nozzle which can be supplied with pressurized cleaning fluid to form a suction flow
Implementation Method 2
a cleaning nozzle which can be supplied with pressurized cleaning fluid via a supply line and which rotates together with the spray arm about the axis of rotation for applying fluid to the surface to be cleaned

AI summary
The invention relates to a surface cleaning head (10) for cleaning a surface, having a cover-like housing (14) open at the bottom in which at least one spray arm (52, 54) is rotatably supported about a rotational axis and supports a cleaning nozzle (56, 58) that can have pressurized cleaning fluid applied thereto, and revolves about the rotational axis together with the spray arm (52, 54) for applying fluid to the surface to be cleaned, and having a jet pump for suctioning off the fluid applied to the surface, wherein the jet pump comprises a jet nozzle (62) that can have pressurized cleaning fluid applied thereto for forming a suction flow. In order to further develop the surface cleaning head such that it can be handled in a simple manner, the invention proposes that the jet nozzle (62) is disposed downstream of the inlet (44) in the housing (14).
