Definitions

  • the present invention relates to a vaporiser for inhaling (vaping) vapours of a liquid, which liquid may for example contain nicotine or nicotine derivatives.
  • Vaping devices now predominantly fall into one of two categories, the first category comprising relatively simple and inexpensive devices. These usually have a reusable casing holding a battery, the casing being arranged to receive a separate pod, which pod is pushed into the top of the casing, where electrical contacts on the pod, for energising a heating element in the pod, make contact with the electrical contacts in the casing. These contacts are switchably connected to the battery within the casing.
  • the pod is normally disposable (by which it is meant that it is not intended to be, and is not arranged to be, refilled) and may be selected from one of a number of interchangeable pods containing liquids of different strengths or flavours.
  • the pod has a central chimney terminating at an upper end in a mouthpiece, through which air can be sucked from an opening at the bottom of the pod through the chimney.
  • the chimney is normally surrounded by a reservoir of the liquid to be vaporised, with a wick, typically of cotton, silica or ceramic extending across the bottom portion of the chimney and through a hole in the wall of the chimney to the reservoir.
  • the heating element which is normally in the form of a coil wrapped around the wick, is connected to contacts on the bottom of the pod which make contact with the contacts in the casing to enable the coil to be energised to vaporise the liquid in the wick for inhaling through the mouthpiece.
  • This type of pod vaping device is popular due to its ease of use and compactness.
  • vape kits The second category of vaping devices are generally intended to be completely reusable and are commonly referred to as vape kits.
  • a vape kit is normally a far larger and chunkier device, having both a larger battery and reservoir, which reservoir is arranged to be refilled.
  • the heating element and wick are not intended to be disposable items and subsequently may fail and need to be periodically replaced.
  • vape kits are bulkier and more expensive to produce than the pod type devices, they offer some significant advantages. Not only do they have a far better battery life, but they also enable the vaping experience to be tailored to a user’s requirements, by providing means for varying one or more of either the temperature of the heating element or the flow of air through the chimney.
  • the present invention aims to provide a new class of vaping device offering advantages over both the above mentioned types.
  • a vaporiser comprising a main body arranged to receive a replaceable pod and a replaceable pod arranged to be received in the main body, the pod comprising: a housing; a reservoir for a liquid to be vaporised; a chimney extending within the housing and permitting air to be drawn through the chimney from an upstream opening of the pod to a downstream opening of the pod; a wick for receiving liquid from the reservoir and a heating element for heating liquid in the wick to vaporise it and create vapour in the chimney, the vaporiser being characterised in that the main body and the pod are arranged such that the pod may be inserted into the main body in one of at least two possible orientations relative to the main body and wherein the rate at which air may be drawn in through an upstream opening, for a given pressure difference between the downstream opening and atmospheric pressure, depends on the orientation of the pod within the main body.
  • a vaporiser in accordance with the present invention may be arranged to provide a relatively compact main body in which the battery is housed and a replaceable pod, which may be refillable but would normally be disposable along with the wick and heating element housed within the pod.
  • the present invention may provide a vaporiser having the advantages of known pod type devices, which are easy to maintain and operate, simply requiring the pod to be replaced as necessary and providing a clean and easy way of changing from one liquid type to another, or for replenishing the liquid.
  • a vaporiser in accordance with the present invention offers the additional advantage over known pod types, of enabling a user to tailor the vaporiser to their own specific requirements at a particular time, simply by choosing which way to insert the pod into the vaporiser. This advantage is provided without incurring any additional cost by the manufacturer and without increasing the bulk of the device to any significant extent
  • the pod has two upstream openings, with one of the upstream openings arranged to be closed, depending on the orientation of the pod within the main body.
  • the above arrangement provides a simple mechanism whereby the ease of drawing air through the vaporiser can simply be determined by determining which one of two or more upstream openings air is to be drawn through, whereby this will determine the resistance to drawing air through the mouthpiece.
  • One simply way of determining which upper opening air will be drawn through is by the main body having a portion which will come into contact and seal one of the two upstream openings of the pod, depending on which way the pod is inserted into the main body.
  • the pod may have two upstream openings on respective opposite side edges of the housing of the pod, or two upstream openings equally spaced from opposite side edges of the housing of the pod, whereby the pod may be received in the main body of the vaporiser in one of two opposite orientations, whereby the said portion of the main body will seal with a first upstream opening on the pod when the pod is received in one orientation and the same portion will seal with the second upstream opening when the pod is received in the main body with the opposite orientation relative to the main body.
  • the ease of drawing air through the mouthpiece may simply be determined by inserting the pod in one orientation or in an opposite orientation.
  • each upstream opening forms an opening directly into the chimney, or where each upstream opening is connected to the chimney by a respective passage
  • each upstream opening, or associated passage forms or has a restriction which acts to restrict airflow through that upstream opening; with the restriction associated with one upstream opening being of a different size to the restriction associated with one other upstream opening.
  • Each restriction may then act to restrict the quantity of air drawn in through the associated upstream opening for a given pressure difference between the downstream opening and atmospheric pressure.
  • the restriction through which air is drawn in to the chimney depends on the orientation of the pod within the main body and thus which upstream opening is open and which upstream opening is sealed by said portion of the main body. This arrangement provides a way in which a restriction may be placed in the airflow simply by determining the size of an associated upstream opening of the pod or the size of a restriction in a passage leading from that upstream opening.
  • the pod may have one upstream opening.
  • the main body of the vaporiser may then have at least one passage arranged to align and seal with the one upstream opening on the pod when the pod is in one orientation and not to seal with the one upstream opening when the pod has a different orientation.
  • the at least one passage having a restriction in it, or forming a restriction, thus acts to restrict the rate at which air is drawn into the upstream opening of the pod through the passage.
  • the main body may comprise two passages each with a restriction of a different size to the other, such that the rate at which air is drawn in through the upstream opening of the pod, for a given pressure difference between the downstream opening and atmospheric pressure, depends on the orientation of the pod within the main body and which passage in the main body the upstream opening of the pod is aligned with. In this manner, the main body may regulate the rate at which air is drawn through the upstream opening of the pod depending on the orientation of the pod within the main body.
  • the chimney within the pod may extend from, or towards, the top of the pod to, or towards, the bottom of the pod, wherein the wick and the heating element are located at, or towards, the bottom of the chimney.
  • the passage associated with the, or each, upstream opening then connects the bottom of the chimney to the, or each, respective upstream opening with the, or each, upstream opening positioned above the level of the bottom of the chimney.
  • the above features may be employed with either of the alternative embodiments described above.
  • the advantage here is that if liquid seeps from the wick and collects in the bottom of the chimney, instead of leaking out of the bottom of the chimney and contaminating the contacts, casing or battery, that liquid will instead be contained within the bottom of the chimney as a result of the upstream openings being above the level of the bottom of the chimney.
  • the main body of the vaporiser has a lower portion and an upper portion between which the pod is received and the pod has the, or each, upstream opening located on an upper face of the pod.
  • This arrangement provides maximum containment of any liquid seeping from the wick and collecting in the bottom of the chimney and will likely contain that liquid even if the vaporiser is laid on its side or is even slightly inverted.
  • the pod and main body may preferably be arranged so that the pod may be received in the main body from a side face of the main body.
  • the pod may be mounted in the side of the main body by single handed operation, using the pressure of the thumb to push the pod easily into an aperture in a side face of the main body.
  • the pod could equally be arranged to be inserted from a side edge of the main body.
  • the main body of the vaporiser may be arranged to have a lower portion and an upper portion between which the pod is received, wherein the upper portion has a mouthpiece extending from a top surface of the upper portion and a chimney extension passage extending through the upper portion to connect the mouthpiece with the downstream opening of the pod.
  • the mouthpiece is no longer a part of the disposable pod and thus the materials of the mouthpiece may be of a superior quality.
  • the mouthpiece may be of stainless steel, which would not be cost effective where the mouthpiece is part of the disposable pod.
  • the chimney in the pod is vertical and passes up the middle of the pod and the chimney extension passage is inclined at an angle to connect to the mouthpiece, which is offset to one side if the main body.
  • the chimney extension passage through the upper portion of the main body being inclined permits the mouthpiece to be offset to the side of the main body, which may be a preferable position for the user. It may also tend to contain any spitting that may sometime occur as liquid is heated at the wick.
  • the main body and pod may both be substantially planar and rectangular with the pod, when received in the body, being visible from both sides of the main body. This may provide a particularly aesthetically pleasing vaporiser and one that is both practical and comfortable to hold.
  • a vaporiser kit may comprise a vaporiser as claimed in any preceding claim and a plurality of different interchangeable main bodies for use with a common pod. In this way, a
  • manufacturer or different manufacturers, may manufacture main bodies of vaporisers in different styles which may all use a common pod, enabling such a pod to become standard for such vaporising devices.
