Definitions

  • the present disclosure relates to the field of electronic atomization devices, and in particular to an electronic atomization device and a heating assembly thereof.
  • an electronic atomization device is a heat-not-burning device.
  • a heating assembly in the electronic atomization device heats a center or a periphery of a to-be-atomized substrate. Since a thermal conductivity and a thermal diffusion coefficient of a heater is relatively low, only a small portion of heat generated by the heater is used to heat the to-be-atomized substrate, and therefore, a small amount of aerosol is generated. Most of the generated heat is conducted to components of the electronic atomization device through solid components that contact the heater. In this way, various components and a housing of the electronic atomization device are heated. In order to increase the amount of the generated aerosol, the amount of heat generated by the heater needs to be increased, which may cause more problems.
  • a heating assembly includes: a fixing member; a movable member; and a heater.
  • the fixing member has a mounting cavity to receive the aerosol-generating assembly.
  • the movable member is received in the mounting cavity and is slidably connected to the fixing member.
  • the heater is detachably arranged on a bottom wall of the mounting cavity and is configured to generate heat in a magnetic field to heat the aerosol-generating assembly.
  • the aerosol-generating assembly is inserted into the tubular case and drives the movable member to move from the first position to the second position.
  • the heater is inserted into the aerosol-generating assembly.
  • the movable member is reset from the second position to the first position.
  • the heater is inserted in the aerosol-generating assembly and is separated from the bottom wall of the mounting cavity, and the heater is spaced apart from the tubular case.
  • the fixing member has an opening, a first end of the heater passes through the through hole, and a second end of the heater cannot pass through the through hole.
  • the heater passes through the through hole to be inserted into the aerosol-generating assembly and is spaced apart from the movable member
  • the heater includes an insertion portion and a blocking portion fixedly connected to an end of the insertion portion.
  • An end of the insertion portion away from the blocking portion serves as the first end, and an end of the blocking portion away from the insertion portion serves as the second end.
  • An inner diameter of the through hole is larger than a cross-sectional size of the insertion portion, and an inner diameter of the through hole is smaller than a cross-sectional size of the blocking portion.
  • the fixing member includes a second annular side wall and a second bottom wall connected to an end of the second annular side wall.
  • the second annular side wall and the second bottom wall cooperatively define the mounting cavity.
  • a side of the second bottom wall near the movable member is arranged with the fixing portion.
  • the fixing portion is configured to fix the heater to maintain the heater staying upright.
  • the fixing member and/or the tubular case has a limiting portion, the limiting portion is configured to limit the tubular case to stay at the second position and maintain the tubular case being spaced apart from the blocking portion of the heater.
  • the fixing portion is a recess, the recess receives the housing and fixes the blocking portion of the heater.
  • a depth of the recess is greater than a height of the blocking portion, and a side wall of the recess serves as the limiting portion.
  • both the recess and the second end of the heater are conical.
  • a portion of the second bottom wall corresponding to the fixing portion is further arranged with a magnetic attraction member to magnetically connect with the heater. Attraction between the magnetic attraction member and the heater is less than a friction force between the heater and the aerosol-generating assembly.
  • the electronic atomization device 100 includes a housing 1, a heating assembly 2, a power supply assembly 3, and an aerosol-generating assembly 4.
  • the housing 1 is configured to mount or receive the heating assembly 2, the power supply assembly 3, and the aerosol-generating assembly 4.
  • the power supply assembly 3 includes a battery 31, an airflow sensor (not shown in the drawings), a controller 32, and so on.
  • the power supply assembly 3 is configured to supply power to the heating assembly 2 and to control the heating assembly 2 operate to heat the aerosol-generating assembly 4 to form aerosols that can be inhaled by a user.
  • the airflow sensor is configured to detect changes in an airflow in the electronic atomization device 100.
  • the controller 32 activates the battery 31 to supply power to the heating assembly 2 based on the changes in the airflow detected by the airflow sensor.
  • the spring 251 in the second compressed state When the force applied to the aerosol generating assembly 4 is released, the spring 251 in the second compressed state generates a resetting force to push the tubular case 221 to slide in a direction away from the second bottom wall 213 of the mounting cavity 211, enabling the tubular case 221 to slide to be reset from the second position to the first position of the mounting cavity 211.
  • the tubular case 221 and the aerosol-generating section 42 drive the heater 23 to slide from the second position to the first position.
  • the heating assembly includes the fixing member, the movable member, and the heater.
  • the fixing member has the mounting cavity to receive the aerosol-generating assembly.
  • the movable member is received in the mounting cavity and slidably connected to the fixing member.
  • the heater is detachably arranged on the bottom wall of the mounting cavity and is configured to generate heat in the magnetic field to heat the aerosol-generating assembly.
  • the aerosol-generating assembly is inserted into the tubular case and drives the movable member to move from the first position to the second position, and the heater is inserted into the aerosol-generating assembly.
