Designed to deliver a consistent and high-quality aerosol output, our compact ceramic heater technology ensures an optimal user experience.
CVS
Ceramic Vaping System
The Ceramic Vaping System is our latest e-cigarette, using a ceramic heater to create a nicotine-containing vapor.
Ceramic Vaping System
Ceramic Vaping System (CVS), commercialized as VEEV ONE, represents our latest advancement in e-vapor technology and delivers consistent taste making this e-vapor product a more acceptable smoke-free alternative. CVS also hosts smart digital controls and a low e-liquid detection system to prevent burnt taste.
The system consists of two main components, intended to be used exclusively together:
- The replaceable cartridge, also named pod, is a disposable closed tank and a non-refillable unit with a mouthpiece that holds the e-liquid, heating element, and electrical components to connect with the battery unit. Its function is to store and heat the e-liquid to generate an aerosol. CVS pods are designed to prevent product misuse and ensure the e-liquid is not altered.
- The battery unit, or device, is a rechargeable unit that holds the battery and the electronics. Its function is to serve as the insertion point for the cartridge and provide energy to the heating element to generate an aerosol.
Heating technology: principle of operation
The heating technology utilized in CVS is founded on a ceramic heater, which features a ceramic microporous substrate with a printed metallic heating track.
The innovative H-shape design for the ceramic heater's geometry increases the e-liquid supply surface area, allowing a sustained e-liquid feed to the metallic heating track during the vaporization process, able to cope with virtually any puffing topography.
Thanks to the new technology the product offers more consistent taste experience, and it is also equipped with our low e-liquid detection system to prevent dry puffs.
Leak-proof system design
The pod's leak-proof design is achieved through a combination of factors, including a grooved structure, reliable seals between its various components, and the microporous ceramic body structure that aids in retaining the e-liquid inside.
Improved airflow path
When air is drawn through the mouthpiece during a puff, it enters from the bottom of the cartridge and passes over the printed heating track, where the e-liquid supplied by the ceramic body is vaporized. The vapors released from the heater are then rapidly cooled by incoming fresh air, triggering aerosol formation via nucleation and condensation. The generated aerosol is then released through the cartridge chimney.
Puff-activation feature
Located in the battery unit, the puff activation feature is an internal sensor connected to the air path which detects a negative pressure (pressure drop) generated by a puff. The heating track will only be powered by the battery unit if a puff is detected.
Low e-liquid detection
The low e-liquid detection system monitors the changes in the resistance of the heating track. When e-liquid is no longer supplied, an increase in temperature takes place within the heater, consequently increasing the electrical resistance. The system detects this change and stops the power supply. In this way, the low e-liquid detection feature is designed to prevent the overheating of e-liquid and dry puffs, which are typically responsible for the formation of undesired aerosol components such as carbonyls.
Revisiting the classic e-cigarette
Classic e-cigarettes use a wick and coil system to heat a nicotine-containing solution. The wick draws the nicotine-containing liquid onto a coil-heating element to heat the liquid and create a vaporized aerosol. In these systems, the temperature of the heater can vary significantly depending on the device and how strongly the e-cigarette is puffed. Several studies have shown that puffing on an e-cigarette when the liquid level is low can result in "dry puffs" that can drastically change the chemistry of the aerosol. Under these conditions, the levels and number of harmful chemicals are significantly higher compared with levels found in e-cigarettes that have sufficient liquid.
The Philip Morris International (PMI) approach to substantiate reduced emissions consumer-facing product statement is based on the WHO 9 list. The WHO 9 was selected, because it allows to provide consumers with accurate and non-misleading information while improving the consistency of the messages across product categories and aligning with industry practices. Furthermore, this approach enables consumers to make educated and informed decisions about the products available on the market including product properties, benefits, and risks.
