  13. 12. The system of claim 1, wherein the heating device conducts electron current energy that is constant, independent of the heating elements, so that the design of the heater with the same current energy determines the temperature.
  14. 13. The system of claim 1, wherein the heating elements are replaceable heaters, and the shape of each heating element has three functional zones, including an internal, external, and device connection zone.
  15. 14. The system of claim 1, wherein the cavity forms an air pocket having a partition.
  16. 15. The system of claim 1, wherein the compressible consumable element is formed from materials selected from the group consisting of: cut, reconstituted, shredded, diced, extruded or granulated materials made from tobacco, hemp, plants, other cellulosic materials, wood fibers, beet fibers, microcrystalline cellulose, plant materials, solid or semi-solid substances, flavoring compounds, aerosol-forming substances, glycerin, propylene glycols and any mixture thereof.
  17. 16. The system of claim 1, wherein one or more compressible consumable elements generate a signal or other data for transmission to the heating device and interpretation by the heating device to restrict the use of unauthorized compressible consumable elements.
  18. 17. The system of claim 15, wherein the compressible consumable element is designed to be wrapped.
  19. 18. The system of claim 15, wherein the compressible consumable element is wrapped in a porous or impermeable wrapper.
  20. 19. The system of claim 18, wherein the wrapper is selected from paper, tobacco, plant leaf, metal, and gel.

Description

State of the art Field of technology [0001] The present invention relates to a heating device for producing an inhalable or consumable aerosol by applying heat to an aerosol-generating composition, so that selected chemical compounds are efficiently extracted and delivered directly to the user. More specifically, the present invention relates to generating an aerosol in a heating device without the need for a separate cartridge connected to the heating device as a site for generating the aerosol. Description of the prior art [0002] Conventional devices that generate aerosols for inhalation by users typically utilize either a disposable element shaped like a cigarette or a separate cartridge containing the disposable element containing the aerosol-generating composition. When a separate cartridge is used, the disposable element may contain an integrated heater and/or polymer inclusions. Accordingly, the heaters in these conventional devices are hidden or attached to the disposable element and are intended to be discarded after each use, resulting in unwanted waste and litter. [0003] Other traditional devices that generate aerosols for inhalation by users typically have heaters permanently attached to the device. Consequently, these permanently attached heaters must be cleaned to optimally generate consumable aerosol from the device, which is undesirable. If the cleaning process is too complex, the entire device may be prematurely discarded before the end of its potential lifespan, resulting in excessive environmental waste and consumer replacement costs. [0004] Such conventional devices are described, for example, in documents RU 2705799, RU 2715782 or RU 2731029, also published as WO 2019030170. The technical solution disclosed in document WO 2019030170 is chosen by the applicant as a prototype of the invention. [0005] Accordingly, the present invention arises from the growing need for a device that would overcome, alleviate and/or mitigate one or more of the above-mentioned and other disadvantages of known devices. Disclosure of the essence of the invention [0006] The present invention relates to a heating device, such as an inhalation device, that uses its own aerosol-generating consumable element, which is more environmentally friendly and also economical for the consumer. [0007] The present invention also relates to such a heating device with heating elements arranged in a special manner for the purpose of sequentially and uniformly conducting, convecting and radiating heat over the entire surface area of the consumable element. [0008] The consumable element intended for placement in the heating device may be, for example, a grain, capsule, pillow, tablet, bag, plate, powder, granule, cutting, tubes, strips, or sheet. The consumable element may be perforated or non-perforated. The consumable element may be wrapped or unwrapped. The wrapper may be porous or non-porous. The porosity of the wrapper may vary from 24 to 30,000 CORESTA units. [0009] The present invention further provides such a heating device in which the consumable element is partially or completely surrounded by heating elements, which maximizes the yield of the product and the resulting aerosol with minimal energy consumption. [0010] The present invention provides such a heating device that creates an inhalable aerosol and that can operate with one or more heating elements, and a temporary or permanent cavity formed by a barrier between the heating elements and the external environment, which encloses the heating elements and allows for the insertion and removal of consumable elements from the cavity and allows for the manual, mechanical and/or electrical replacement of the heating element of the device. [0011] The present invention further provides such a heating device that protects the user from burns or electric shock during operation and maintenance of the heating device by means of control mechanisms that prevent the user from opening the device while the heater is hot. The device may also have control mechanisms that prevent the heaters from turning on when the device is open. The device may also have a user authentication mechanism and/or user age verification mechanism. [0012] The present invention also provides that the consumable elements may be made from tobacco, other botanicals, herbs or plants, and/or synthetic (e.g., pharmaceutical) products. The consumable element may also contain aerosol-forming ingredients such as, but not limited to, glycerin, propylene glycol, and the like. [0013] The present invention relates to a heating device that creates an inhalable aerosol and that is operable with: (1) one or more heating elements; (2) a temporarily or permanently formed cavity defining the heating elements, circulating air filling the cavity, and an active sacrificial element both outside the device and in an unheated portion of the device; (3) any method or mechanism that allows the sacrificial elements to be inserted and rem
