Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers face issues with controlling the flow rate and pressure at the liquid inlet, leading to matrix liquid leakage without being atomized, affecting user experience and efficiency.
Innovation Solution
The atomizer incorporates a liquid retaining structure on the sealing member to partially block the liquid inlet, adjusting flow rate and pressure to match the atomization process, and includes liquid guide plates to direct atomized liquid efficiently to the atomizer core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid inlet is designed without blocking structures, then the liquid flow rate and pressure are high, but matrix liquid leaks from the atomizer core into the exhaust port without being atomized
Solution Approach 1:
The patent applies local quality by introducing a liquid retaining structure that selectively blocks specific regions of the liquid inlet while leaving other areas open. This localized blocking approach allows the system to maintain high liquid flow rate through unblocked areas while preventing leakage through the blocked areas, thus resolving the contradiction between productivity and harmful liquid leakage.
Solution Approach 2:
The liquid inlet is segmented into multiple regions by the liquid retaining structure, dividing the flow path into blocked and unblocked areas. This segmentation allows independent control of liquid flow in different regions, enabling the system to optimize both flow rate through open areas and leakage prevention through blocked areas simultaneously.
2Object-generated harmful factors
If the liquid inlet is partially blocked by the liquid retaining structure, then matrix liquid leakage is reduced, but the flow rate and pressure control becomes more complex
Solution Approach 1:
The liquid retaining structure serves as an intermediary component between the liquid reservoir and the atomizer core. It mediates the liquid flow by providing a simple geometric blocking function that passively regulates flow rate and pressure without requiring complex control mechanisms, thus reducing leakage while maintaining system simplicity.
Solution Approach 2:
The liquid retaining structure changes the flow parameters (flow rate and pressure) by creating a geometric constraint on the liquid path. This physical parameter change is achieved through the structure's shape and position rather than through active control, simplifying the overall system while effectively managing liquid flow.
3Productivity
If the liquid retaining structure is designed with precise blocking, then flow rate and pressure are optimized for atomization, but the manufacturing precision requirements increase
Solution Approach 1:
The liquid retaining structure is designed to provide sufficient blocking to prevent leakage, even if the positioning is not perfectly precise. This partial blocking approach ensures that as long as the structure is roughly in the correct position, it will effectively prevent liquid leakage without requiring extremely tight manufacturing tolerances, thus balancing atomization efficiency with manufacturing feasibility.
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
Reduces matrix liquid leakage, enhances user experience, and improves atomization efficiency by ensuring consistent flow and pressure compatibility with the atomizer core, while extending the atomizer core's service life.
Implementation Method 1
the flow rate and pressure at the liquid inlet are difficult to be controlled. Excessive liquid flow rate and/or pressure at the liquid inlet can easily cause some matrix liquid to leak from the atomizer core into the exhaust port without being atomized
Implementation Method 2
The matrix liquid is atomized and aerosols are generated through the heating of the atomizer core
Implementation Method 3
the liquid guide plate is configured to direct an atomized liquid toward the liquid inlet of the atomizer core

AI summary
The present application relates to the technical field of atomization devices, and provides an atomizer (100) and an atomization device. The atomizer (100) includes: a housing (11) provided with a nozzle (1111) at one end of the housing (11) in a first direction, and an exhaust duct (1112) in communication with the nozzle (1111) is provided within the housing (11); a first sealing member (12) disposed within the housing (11) and divided an interior space of the housing (11) into a liquid storage chamber (1113) and an air inlet chamber (1114), the first sealing member (12) is provided with a first mounting hole (121), and an end of the first sealing member (12) facing the nozzle (1111) is provided with a liquid retaining structure (122); an atomizer core (13) disposed within the liquid storage chamber (1113), an end of the atomizer core (13) being in communication with the exhaust duct (1112), and another end of the atomizer core (13) extending into the first mounting hole (121) and being sealingly connected with the first mounting hole (121); in which a side wall of the atomizer core (13) is provided with at least one liquid inlet (1311), and at least one of liquid inlets (1311) is disposed corresponding to the liquid retaining structure (122) in a lateral direction of the atomizer core (13), and is partially blocked by the liquid retaining structure (122). The above-described technical solution of the present application can reduce the liquid flow rate and pressure of the atomizer core (13) in front of the liquid inlet (1311) via the liquid retaining structure (122), thereby reducing the possibility of matrix liquid at the liquid inlet (1311) leaking through the atomizer core (13) without being atomized, thus improving the user experience and reducing the waste of the matrix liquid.
