Solution Overview
Problem
Existing electronic cigarette atomizing cores face issues with insufficient e-liquid contact and pressure imbalances in the liquid storage chamber, leading to problems like inadequate vapor production, leakage, and inefficient e-liquid seepage.
Innovation Solution
The atomizing core features a porous ceramic material with a recessed seepage surface and an atomizing surface, including a protruding column and inclined surfaces to increase e-liquid contact area, and a cartridge design with balance air grooves to maintain air pressure balance within the liquid storage chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the e-liquid slot is recessed from the e-liquid suction surface, then the atomizing core structure is simplified, but the contact surface between the e-liquid slot and the e-liquid is insufficient, causing inadequate vapor production
Solution Approach 1:
The invention transforms the traditional recessed e-liquid slot design into a protruding column structure that extends upward from the e-liquid suction surface. This dimensional change increases the contact surface between the e-liquid and the atomizing core, allowing for better e-liquid absorption and vaporization, thereby resolving the contradiction between structural simplicity and vapor production quantity.
Solution Approach 2:
The atomizing core employs a porous structure with capillary holes that enhance e-liquid absorption and distribution. The porous material increases the effective contact surface area between the e-liquid and the heating element, improving vapor production without significantly complicating the overall structure.
2Reliability
If the liquid storage chamber is in a sealed state, then e-liquid leakage is prevented, but the liquid storage chamber may be in a negative pressure state, causing e-liquid to fail to seep through the atomizing core
Solution Approach 1:
The invention introduces air holes in the housing that can change their state between open and closed based on internal pressure conditions. When the liquid storage chamber is in negative pressure, the air holes open to allow air intake and restore pressure balance, enabling e-liquid to seep through the atomizing core. When pressure is normal or positive, the air holes remain closed to prevent e-liquid leakage, thus resolving the contradiction between leakage prevention and e-liquid seepage.
3Reliability
If the liquid storage chamber is in a sealed state, then e-liquid leakage is prevented, but under the influence of temperature, humidity, air pressure, etc., some e-liquid in the liquid storage chamber vaporizes, producing excessive high pressure that may cause e-liquid to completely seep through the atomizing core
Solution Approach 1:
The air holes in the housing dynamically respond to pressure changes within the liquid storage chamber. When temperature, humidity, or air pressure causes e-liquid vaporization and pressure increase, the air holes open to release excess pressure, preventing complete e-liquid seepage. When pressure is normal, the holes remain closed to maintain leakage prevention, thus resolving the contradiction between leakage prevention and pressure control.
4Adaptability or versatility
If the electronic cigarette is placed in an inverted state, then portability is improved, but the e-liquid is away from the e-liquid slot, causing insufficient vapor production upon immediate inhalation
Solution Approach 1:
The protruding column structure of the e-liquid slot extends upward from the e-liquid suction surface, creating a larger contact area that can reach e-liquid even when the device is inverted. This dimensional modification ensures that the atomizing core maintains contact with e-liquid regardless of device orientation, resolving the contradiction between portability and vapor production.
Solution Approach 2:
The porous structure of the atomizing core with capillary holes enables passive e-liquid transport through capillary action, allowing e-liquid to reach the heating element even when gravity works against it (inverted position). This ensures consistent vapor production regardless of device orientation.

AI summary
An atomizing core and a cartridge are provided. The atomizing core includes an atomizing surface and a seepage surface opposite to the atomizing surface. The seepage surface is recessed downward to form an e-liquid slot. A heating wire is disposed on the atomizing surface. The atomizing core is made of a porous ceramic material. The atomizing core is formed with a plurality of capillary hole structures from the seepage surface to the atomizing surface after the atomizing core is fired. A part of the e-liquid slot protrudes upward to form a protruding column, and an inclined surface is disposed on a peripheral wall of the protruding column facing the e-liquid slot. The present disclosure effectively avoids a problem that the seepage of the e-liquid is insufficient in a case that the e-liquid is in a small amount.
