Definitions

  • the present invention falls within the field of daily necessities and relates to an electronic cigarette according to the preamble of claim 1.
  • Prior art, technological background of the invention
  • each electronic cigarette has at least the following functional elements: an energy source, electronic control components, a precursor composition and a
  • Atomizer device can consist of a heating element (e.g. filament or heating chip) or some other assembly that is capable of converting the precursor composition into an aerosol, e.g. with the help of an ultrasonic atomizer or a single or two-component atomizer nozzle.
  • the precursor composition can on the one hand consist of the liquid already mentioned or on the other hand contain solid components, such as. B. prepared tobacco products (so-called heat-not-bum products).
  • Electronic cigarettes are designed to be used like traditional tobacco cigarettes.
  • a usage scenario which is the rule when consuming a traditional tobacco cigarette and is therefore in the range of what is expected for electronic cigarettes, would consist in inhaling the aerosol generated by the electronic cigarette several times in a row with short pauses between the individual puffs.
  • Such a process in which the electronic cigarette is usually held in the hand, brought to the mouth and finally the aerosol is inhaled in the form of a kind of mist or vapor and partly exhaled again, is also influenced by a desired visibility and perceptibility to outsiders .
  • the smoking of traditional tobacco cigarettes has been and is massively promoted in many parts of the world. It has been and is sometimes tried to associate it with positive values such as sociability, authenticity and freedom.
  • Lifespan options for customizing the exterior design, for example through the interchangeability of assemblies, a small product size that is pleasant to handle or feel and easy to use, and dimensions that come as close as possible to the shape and size of a classic tobacco cigarette , as it can be assumed that many people are used to the shape and size of classic tobacco cigarettes and also to their weight. Furthermore, aspects such as environmental friendliness, waste minimization, recyclability and waste separation of materials are important today. The same applies to the choice of material. Selected materials, such as z. As wood or hard rubber are smokers Z igaretten related products such as tobacco pipes well known, whereby the use of such materials in electric cigarettes also a familiarity with smokers may be able to cause.
  • control electronics in the electronic cigarette should ensure reliable and safe functioning of the aerosol generation and, if necessary, include extended functions, such as the possibility of a Bluetooth connection to a smartphone or authentication of the consumable in a so-called cartridge and quantity control or various safety functions, such as protection against unintentional triggering of the switch-on device, for example during transport, or a child safety device;
  • extended range of functions goes hand in hand with an increased space requirement for electronic components or for electronic components, for example for more complex circuit structures in and around integrated circuits.
  • Such control electronics also include a
  • Switch-on element in the form of a switch, button or sensor, which is able to register a movement of the customer (z. B. pressure sensor, air flow sensor, temperature sensor), and possibly display elements, such as. B. a FED, and components for evaluation. Furthermore, the modularity of electronic cigarettes for the purpose of exchanging individual components in the case of
  • a circular-cylindrical housing shape for example, means that the battery cell must also be circular-cylindrical in order to be able to fit optimally into this shape.
  • cuboid battery cells with a higher capacity can be realized with the same volume than circular cylindrical battery cells. This is due to the basic layer structure of battery cells. In the case of a round cell, the electrode and separator layers are usually rolled up, which creates an empty cavity in the middle due to the limited angle of curvature of the layers used. This makes efficient use of installation space in a circular cylindrical housing all the more important.
  • a cuboid housing structure also accommodates the construction of printed circuit boards.
  • a flat and rectangular circuit board shape can be implemented more easily without sacrificing size or functionality and at the same time can be integrated into a cuboid housing in a space-efficient manner.
  • the electronic components with which the circuit board of a control unit is fitted are often themselves rectangular, so they can be arranged more efficiently on a rectangular circuit board surface than on a round one.
  • a cuboid housing is therefore more compatible with the design of battery cells and circuit boards than would be the case with a circular cylindrical housing and would, for example, address the conflicting objectives of small product size, the most powerful battery cell possible and good space utilization Simplify PCB. As a result, however, one moves away from the goal of resemblance to the tobacco cigarette.
  • a simple assembly of the electronic cigarette can conflict with increasingly complex control electronics, which sometimes result in the use of flexible circuit boards or various cabling and additional parts for connecting the circuit board to the housing, for example injection molded parts, etc.
  • Simple technical operation can also have negative effects on the space requirement and the product size; it is also desirable that the electronic cigarette remains in an assembled and virtually functional state while the battery is being charged. For security reasons, it may also be necessary that the charging and A virtually functional electronic cigarette is also blocked for intended use - if someone pulls on the device while it is being charged. Such chargeability may take up additional space in contrast to a permanent lock, which does not perform any further functions, for example because additional cabling may be required. Likewise, increased demands on functionality or on the electrical construction can lead to increased space requirements. The detection of changes in the air pressure or air flow rate during the smoking process, so that the electronic cigarette can be used like a tobacco cigarette, makes air flow management necessary, for example. Often, additional components are used in addition to a pressure sensor.
