E-cigarette personal vaporizer

Abstract

A user-replaceable e-liquid cartridge adapted to be inserted into or attached to a portable, personal storage and carrying case for an e-liquid e-cigarette PV. The combination of cartridge and case forms in normal use a portable, personal device for the storage and carrying of the PV and its re-filling with e-liquid.

AI Technical Summary

Problems solved by technology

Specifically, an effective e-liquid PV consumes a significant amount of e-liquid and also current.

Cigalites have not sold well in the market because they permit neither high e-liquid consumption nor high current.

Cases that can merely re-charge a PV are not good enough because the PVs need to be frequently re-filled with e-liquid, which means dis-assembling them, which is messy and inconvenient.

This high consumption would, with a conventional PV design be highly inconvenient because of the need to disassemble the PV and manually drip e-liquid into a small reservoir by squeezing a bottle of e-liquid.

It would be possible also to include power control buttons, dials etc on the Case 100 itself, although this would add to complexity and cost.

There may some residue of the previous flavour in the pump, possibly affecting the vaping experience.

A significant problem with conventional e-cigarette PV designs is that re-filling a cartridge reservoir is slow and can be messy; it typically requires the user to purchase small bottles of e-liquid and to carefully dis-assemble the PV and then re-fill the cartridge by lining up the nozzle of a bottle and squeezing gently.

Equally, removing a spent, non-refillable cartridge and replacing it with a new cartridge, whilst not messy, is wasteful, especially as typical cartridges are not recyclable.

This kind of indicator is very useful because if the user tries to inhale before the atomizer is effectively able to create a vapour with the correct characteristics (which happens if the e-liquid is too cool and viscous), then the user experience is very poor.

In conventional PVs with a small rechargeable battery, time can generally not be used as a proxy because users do not reliably keep the battery close to fully charged.

Absorption materials should not absorb moisture in vapour suspension as this would harm inhalation, only liquids that are free moving in the vapouriser case are absorbed.

It is highly unlikely that the wick will itself permit the migration of droplets of e-liquid that could then leak out from the mouthpiece.
