Definitions

  • the present application relates to the technical field of atomization, and particularly to atomizers.
  • An aerosol is a colloidal dispersion system formed by dispersing and suspending small solid or liquid particles in a gas medium.
  • the aerosol can be absorbed by the human body through the respiratory system, providing users with a new alternative absorption method.
  • An atomizer refers to a device that is adapted to form an aerosol from a stored atomizable medium by means of heating or ultrasound treatment.
  • a heat-not-burn aerosol-generating substrate is a new kind of substrate that is to be heated by a special heat source and substrate (the heating temperature is below 500°C or even lower), and various substances in the substrate atomized in heating are volatilized to produce an aerosol to meet the needs of smokers.
  • the heat-not-burn aerosol-generating substrate does not produce flames and soot during the suction process, which is friendly to the environment and can provide the users with a good experience while reducing harmful substances that are produced by pyrolysis of conventional substrates during combustion, and thus is less harmful to the users.
  • the existing atomizer used for atomizing the heat-not-burn aerosol-generating substrate includes a heating chamber. After the aerosol-generating substrate is inserted in the heating chamber, an external airflow enters the aerosol-generating substrate from the bottom of the substrate. The airflow and the effective substances such as aroma generated from the heated aerosol-generating substrate are mixed and then inhaled by the user. However, the airflow flowing into the bottom of the aerosol-generating substrate reduces the temperature of the aerosol-generating substrate, not allowing the substances in the aerosol-generating substrate to be thoroughly baked, so that the effective substances cannot be completely released, which leads to a decreased amount of the effective substances contained in the aerosol output from the atomizer, and thus reduces the user experience of the atomizer.
  • An aspect of the present application provides an atomizer, which is adapted to heat and atomize an aerosol-generating substrate.
  • the aerosol-generating substrate includes a substrate section, a hollow section, and a filter section connected in sequence.
  • a side wall of the hollow section is provided with a first air inlet, and a side wall of the substrate section at an end adjacent to the hollow section is provided with a second air inlet.
  • the atomizer includes a main body having an accommodating cavity, and the accommodating cavity has an open end and a closed end opposite to each other.
  • the substrate section and the hollow section of the aerosol-generating substrate are adapted to be inserted in the accommodating cavity.
  • a gap is adapted to be defined between the aerosol-generating substrate and the side wall of the accommodating cavity, forming a first airflow channel that is in communication with the first air inlet and a second airflow channel that is in communication with the first airflow channel and the second air inlet.
  • the first airflow channel is in communication with the open end of the accommodating cavity.
  • the aerosol-generating substrate is adapted to abut against a bottom wall of the accommodating cavity forming the closed end.
  • the atomizer further includes at least two supports, each of which protrudes from the side wall of the accommodating cavity and is located in the second airflow channel, wherein an airflow passage is defined between two adjacent supports.
  • a bottom wall of the accommodating cavity forming the closed end is provided with a second air outlet.
  • the atomizer further includes an atomization assembly, wherein the atomization assembly is located in the main body, and the main body defines an air outflow channel therein, one end of the air outflow channel is in communication with the atomization assembly, and another end of the air outflow channel is in communication with the first air outlet and the second air outlet.
  • the atomizer further includes a sealing support, wherein the sealing support is protrudes from the end of the side wall of the accommodating cavity adjacent to the open end to seal the accommodating cavity.
  • the gap between the aerosol-generating substrate and the side wall of the accommodating cavity is 0.3 mm to 1 mm.
  • An aspect of the present application provides an aerosol-generating system including the atomizer and the aerosol-generating substrate.
  • the heating temperature in the heating section is relatively stable, and the baking degree of the aerosol-generating substrate will not be affected due to significant changes in the heating temperature, so that the aerosol-generating substrate can be fully baked in the accommodating cavity and the effective substances therein can be fully released, improving the taste of the generated aerosol, and thereby effectively improving the user experience of the atomizer.
  • first and second are used merely as labels to distinguish one element having a certain name from another element having the same name, and cannot be understood as indicating or implying any priority, precedence, or order of one element over another, or indicating the quantity of the element. Therefore, the element modified by “first” or “second” may explicitly or implicitly includes at least one of the elements. In the description of the present disclosure, "a plurality of' means at least two, such as two, three, etc., unless otherwise specifically defined.
  • the terms “installed”, “connected”, “coupled”, “fixed” and other terms should be interpreted broadly.
  • an element when being referred to as being “installed”, “connected”, “coupled”, “fixed” to another element, unless otherwise specifically defined, may be fixedly connected, detachably connected, or integrated to the other element, may be mechanically connected or electrically connected to the other element, and may be directly connected to the other element or connected to the other element via an intermediate element.
  • an element when being referred to as being located “on” or “under” another element, may be in direct contact with the other element or contact the other element via an intermediate element.
  • the element when being referred to as being located “on”, “above”, “over” another element, may be located right above or obliquely above the other element, or merely located at a horizontal level higher than the other element; the element, when being referred to as being located “under”, “below”, “beneath” another element, may be located right below or obliquely below the other element, or merely located at a horizontal level lower than the other element.

  • the main body 120, 210 has an accommodation space with an opening at one end.
  • the heating tube 140, 230 is a hollow tubular structure.
  • the heating tube 140, 230 is accommodated in the accommodation space and located at an end away from the opening.

  • the second airflow channel 1634, 2543 is in communication with the first airflow channel 1632, 2541 and the second air inlet 321.
  • the gap between the aerosol-generating substrate 300 and the side wall of the accommodating cavity 160, 250 is 0.3 mm to 1 mm, so that the airflow can flow smoothly.
  • the airflow outside the aerosol-generating substrate 300 can first flow into the first airflow channel 1632, 2541.
  • a part of the airflow flows from the first airflow channel 1632, 2541 to the hollow section 340 through the first air inlet 341.
  • the other part of the airflow enters the substrate section 320 through the second airflow channel 1634, 2543 and the second air inlet 321, and then carries the aerosol and other effective substances generated in the substrate section 320 to the hollow section 340 to merge with the part of the airflow directly from the first airflow channel 1632, 2541 in the hollow section 340.
  • a first embodiment of the present application provides an atomizer 100.

  • the airflow in the second airflow channel 1634 can flow through the airflow passage between the two adjacent supports 180, so the supports 180 will not hinder the airflow. It can be understood that the number, shape and location of the supports 180 are not limited, and can be set according to needs to meet different requirements.
