Rotatable Spray Head Cover for Pollution Prevention and Loss Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray devices require removal of the spray head cover for operation, leading to potential loss and poor user experience, and lack of a cover results in spray head pollution.
Innovation Solution
A spray device with a rotatable spray head cover that communicates with the spray head assembly, allowing for easy operation and prevention of pollution by locking when not in use, featuring a rotation mechanism and locking mechanism to ensure secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spray head cover is used in conventional spray devices, then the spray head is protected from pollution, but the cover needs to be removed for operation which leads to potential loss and poor user experience
Solution Approach 1:
The spray head cover is merged with the spray button function, integrating the protective cover and the actuating button into a single component. This allows the cover to remain on the device during operation, eliminating the risk of loss while enabling spray function through button pressing.
Solution Approach 2:
The spray head cover is designed to be rotatable between a closed position (protecting the spray head) and an open position (allowing spray). This dynamic positioning allows the cover to adapt between protection mode and operation mode without being removed from the device.
2Ease of operation
If the spray head cover is made detachable for easy operation, then operation becomes simpler, but the cover is easy to lose
Solution Approach 1:
The spray head cover is merged with the spray button function, integrating the protective cover and the actuating button into a single component. This allows the cover to remain on the device during operation, eliminating the risk of loss while enabling spray function through button pressing.
3Ease of operation
If no spray head cover is used to simplify operation, then the device is easier to use, but the spray head is easy to cause pollution
Solution Approach 1:
The spray head cover is merged with the spray button function, integrating the protective cover and the actuating button into a single component. This allows the cover to remain on the device during operation, eliminating the risk of loss while enabling spray function through button pressing.
Solution Approach 2:
The spray head cover is designed to be rotatable between a closed position (protecting the spray head) and an open position (allowing spray). This dynamic positioning allows the cover to adapt between protection mode and operation mode without being removed from the device.
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 device provides a simple, convenient, and user-friendly operation with effective prevention of spray head pollution, enhancing user experience and device functionality.
Implementation Method 1
a liquid vaporization medium in the liquid storage cavity is configured to be sprayed out from the spray hole
Data Source
AI summary
A spray device includes: a housing; a spray head assembly; and a spray head cover. A liquid storage cavity is provided inside the housing. The spray head assembly partially protrudes from the housing and is in communication with the liquid storage cavity, the spray head assembly including a spray nozzle. The spray head cover is rotatably arranged on the housing and covers the spray head assembly, a spray hole being provided on the spray head cover. When the spray head cover is rotated to a first position, the spray hole is correspondingly in communication with the spray head assembly, and when the spray head assembly is pressed, a liquid vaporization medium in the liquid storage cavity is configured to be sprayed from the spray hole. When the spray head cover is rotated to a second position, the spray head cover covers the spray nozzle and is locked with the housing.
