Venting device with splash guard and power tool with such a venting device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing venting devices in power tools, such as high-pressure washers, allow a significant amount of splashing water to penetrate into the interior, leading to operational inefficiencies and potential damage.
Innovation Solution
The venting device features a deflection section oriented at an angle of less than 90° relative to the central section, causing splashing water to bounce back and exit through venting slots rather than entering the interior, with additional design features like a concave common surface and stair-like slat arrangement to enhance water directionality and collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the deflection section extends transversely to the demolding direction to deflect splashing water, then water deflection capability is improved, but a large quantity of splashing water can still penetrate into the interior
Solution Approach 1:
The patent changes the angular parameter of the deflection section, orienting it at an angle of less than 90° relative to the central section. This parameter modification optimizes the reflection angle of splashing water, causing water to bounce back toward the exterior rather than penetrating into the interior, thereby resolving the contradiction between water deflection and interior protection.
2Object-affected harmful factors
If the deflection section is oriented at an angle of less than 90° relative to the central section, then splashing water is thrown back with greater probability, but the structural complexity increases
Solution Approach 1:
The deflection section is divided into multiple regions with different orientations. The first region is oriented at an angle of less than 90° relative to the central section to reflect water back, while the second region is oriented at an angle of greater than or equal to 90° to allow controlled water penetration. This segmentation enables differentiated water management across different areas of the venting device.
Solution Approach 2:
Different regions of the deflection section are assigned different functional qualities: the first region is optimized for water reflection with a specific angular orientation, while the second region is optimized for controlled water penetration. This local differentiation of properties allows the single deflection section to perform multiple functions simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration significantly reduces the amount of splashing water that enters the venting device interior, improving operational efficiency and protecting internal components from water ingress.
Implementation Method 1
a kind of reflection of the splashing water at the deflection section takes place. Due to the orientation of the region of the deflection section at an angle of less than 90° relative to the central section, splashing water which is impinging on the deflection section is thrown back

AI summary
A venting device with a splash guard for deflection of splashing water entering the interior of the venting device has slats with a front section arranged at the exterior. Venting slots are formed between the front sections. At least one of the slats has a deflection section arranged at the interior and a central section connecting deflection section and front section. The front section and the deflection section are angled relative to the central section. The front section of the at least one slat in the operating position of the venting device extends from the central section toward the top side. The deflection section extends in the operating position from the central section toward the bottom side. The deflection section has a region oriented at an angle of less than 90° relative to the central section. A power tool with such a venting device is provided.
