Multi-nozzle Spray Head with Needle Valves for Uniform Makeup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic makeup machines with single-nozzle spray heads face challenges in achieving uniform application and versatility in creating different makeup looks due to limited control over the spraying process, requiring frequent movement and prolonged procedures.
Innovation Solution
A multi-nozzle spray head with axially movable needle valves that can synchronously or individually open and close ejection holes, allowing for uniform material distribution and independent control of different materials at the same location, reducing the need for head movement and speeding up the makeup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single-nozzle spray head is used, then the device complexity is low, but the uniformity of material application is poor
Solution Approach 1:
The spray head is divided into multiple nozzles (first nozzle, second nozzle, etc.), each with its own ejection hole and needle valve. This segmentation allows independent control of material flow from different angles, improving application uniformity while maintaining manageable complexity through modular design
2Adaptability or versatility
If a single-nozzle spray head is used, then the device structure is simple, but the versatility for different makeup looks is limited
Solution Approach 1:
Multiple nozzles with independent needle valves enable selective activation for different makeup techniques (e.g., contouring, highlighting, base application), providing versatility without requiring complete system redesign
Solution Approach 2:
The multi-nozzle spray head serves multiple makeup functions simultaneously - different nozzles can apply different materials (cosmetic material, fixing material) or the same material in different patterns, making the device universally applicable to various makeup looks
3Productivity
If the spray head must be moved frequently to achieve different makeup effects, then the adaptability is maintained, but the productivity decreases
Solution Approach 1:
The needle valves are designed to be dynamically controllable, allowing rapid switching between open and closed states. This enables quick transition between different nozzle configurations and material applications without physical head movement, improving both productivity and adaptability

AI summary
A makeup machine includes a multi-nozzle spray head and a plurality of needle valves. The multi-nozzle spray head has a main body and a plurality of nozzles. Each of the nozzles includes an interior chamber and an ejection hole, and the interior chamber is communicated with the ejection hole. The needle valves are disposed in the main body and axially aligned with the ejection holes. The needle valves are configured to be axially movable away from the corresponding ejection holes to open the ejection holes and to be axially movable towards the corresponding ejection holes to close the ejection holes. Further, the needle valves are capable of synchronously or individually moving with respect to the main body.
