Spray Head With Elastic Spheroid Brush Rods for Scalp Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray heads for body cleaning devices are inadequate in thoroughly cleaning the scalp, particularly for curly hair, as they fail to penetrate effectively and provide adequate cleaning and massaging action.
Innovation Solution
A spray head with brush rods featuring spheroids at the end, made of elastic material, that penetrate through hair to reach the scalp, serving as both a comb and massager, ensuring thorough cleaning and reducing pressure with a larger contact surface area, while water passages facilitate efficient water distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional spray heads are used, then the structure is simple, but the cleaning effectiveness on scalp and curly hair is insufficient
Solution Approach 1:
The spray head combines multiple functions into a single integrated structure: spray holes for water delivery, brush rods for penetration and combing, and spheroids for massaging. This merging of functions (cleaning, combing, massaging) into one component resolves the contradiction by achieving reliable cleaning effectiveness without requiring multiple separate devices
Solution Approach 2:
The spray head is designed as a multi-functional device that can penetrate hair, spray water, comb through curls, and massage the scalp simultaneously. This universal design allows a single spray head to perform multiple cleaning-related tasks, improving reliability while maintaining structural efficiency
2Ease of operation
If brush rods without spheroids are used, then the structure is simpler, but the massaging effect and pressure distribution are insufficient
Solution Approach 1:
Spheroids are attached to the end portions of the brush rods to provide a curved, rounded contact surface with the scalp. This spherical geometry distributes pressure more evenly across the scalp surface, enhancing comfort and massaging effect while preventing concentrated pressure points that would occur with flat or sharp brush ends
Solution Approach 2:
The brush rods are made from elastic materials that combine structural integrity with flexibility. This composite approach allows the brush rods to maintain their shape for effective hair penetration while being soft enough to comfortably contact and massage the scalp, resolving the contradiction between structural simplicity and operational comfort
3Reliability
If spray holes without brush rods are used, then the structure is simpler, but water cannot effectively penetrate through hair to reach the scalp
Solution Approach 1:
The brush rods act as intermediaries between the spray holes and the scalp. They physically push through the hair barrier to create channels, allowing water from the spray holes to follow the same path and reach the scalp effectively. This intermediary function resolves the contradiction by enabling water penetration without requiring high pressure or complex delivery mechanisms
Solution Approach 2:
The brush rods perform preliminary action by penetrating through the hair layer before water is sprayed. This pre-clearing of the path through hair ensures that subsequent water application can directly reach the scalp, improving water penetration reliability while keeping the spray head structure relatively simple
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
The spray head effectively cleans the hair and scalp, providing a massaging effect and alleviating pressure, ensuring thorough cleaning of the scalp and hair near the scalp area, even for curly hair.
Implementation Method 1
The spheroid made of an elastic material can be deformed to ease the interaction between the scalp and the spray head. Meanwhile, the spherical structure may increase the force bearing surface of the scalp so as to alleviate the pressure produced on the scalp

AI summary
The embodiments of the present invention relate to a spray head and a body cleaning device, the spray head comprising: a spray head body comprising a panel provided with spray holes, the panel being provided with a plurality of brush rods, each of which forming a spheroid at an end portion thereof that faces away from the spray head body. The spheroid is made of an elastic material. The spray head, during its use, can penetrate through hair to thoroughly clean the scalp and the bottom portion of the hair near the scalp.
