Definitions

  • the present disclosure pertains to the technical field of electronic smoking device, and more particularly relates to a multifunctional electronic smoking device for circumferentially heating.
  • a novel smoking device for heating tobacco only has a heating module. At this time, there is no device that is capable of properly combining electronic atomization with a low-temperature baking technique. Moreover, some of the existing electronic atomization devices on the market need to repeat e-liquid injection, which is inconvenient and unsanitary.
  • the existing circumferential heating element employs a ceramic material, so that the heating speed is slow, the strength of the heating element is low, and the heating element is readily broken off. Furthermore, the heating element easily produces residue which is inconvenient to clean.
  • Electronic cigarettes or the smoking device are generally provided with a push-button switch, without a lock capability for the power source. This makes misusage of the device likely and, poses a potential safety hazard to children and others. Such a device is known, for example, from EP 3 228 199A or CN 107411179 A .
  • the objective of the present disclosure is to provide a multifunctional electronic smoking device for circumferentially heating, which effectively solves the problems of electronic cigarettes and low-temperature baking cigarettes such as a dissimilar smoking experience, nonuniform circumferential heating, and being unlocked.
  • a multifunctional electronic smoking device for circumferentially heating including:
  • the main body 1 further includes the inner housing 11, the electrical core 9, and the airflow sensor 5.
  • the inner housing 11 includes the heating chamber 1103 and the atomizing chamber 1102.
  • the heating chamber 1103 is connected to the atomizing chamber 1102 through the air inlet slot 1101 for ventilation.
  • the heating chamber 1103 is provided with the heating assembly 3.
  • the heating assembly 3 includes the heating cup 305, the fixed sleeve 301, the outer housing 302 and the snap holder 307.
  • the bottom and the opening of the heating cup 305 are fixed in the outer housing 302 by the snap holder 307 and the fixed sleeve 301, respectively.
  • a gap is arranged between the heating cup 305 and the outer housing 302, and is filled with the thermal insulation layer 303.
  • the temperature sensor 304 is arranged on an outer wall of the heating cup 305.
  • the heating cup 305 is a heating glass cup, and a heating element on the heating cup 305 is the resistance-type printed heating circuit 3051.
  • the atomizing assembly 2 includes the atomizing holder 206, the e-liquid storage cover 202 and the e-liquid storage chamber 201.
  • the e-liquid storage chamber 201 is fixed on the e-liquid storage cover 202.
  • the atomizing wire 204 is arranged on the atomizing holder 206, and is electrically connected to an electrode 207.
  • the slide switch 101 includes the Hall element 1011, the magnet 1012, and the push button 1013.
  • the magnet 1012 is fixed on the push button 1013.
  • the Hall element 1011 is located at a position allowing the Hall element 1011 to sense a presence of a magnetic field of the magnet 1012 when the push button 1013 slides to a first position, and to sense a disappearance of the magnetic field of the magnet 1012 when the push button 1013 slides to a second position,.
  • a sensor airflow passage is defined by the gap on the outer housing of the smoking device, the gap between the airflow sensor 5 and the inner housing, and an air hole of the bottom of the heating cup 305.
  • the heating chamber 1103 is connected to the atomizing chamber 1102 through the air inlet slot 1101 for ventilation, so as to collectively define a smoke airflow passage.
  • the sensor airflow passage is arranged in parallel with the smoke airflow passage and is connected to the smoke airflow passage through the vent hole 12 for ventilation.
  • a ventilation connection point is located on an upstream side of the heating assembly 3 and is located on a downstream side of the smoke airflow passage.
  • the airflow sensor 5 is located in the sensor airflow passage.
  • the smoking device enters a working state
  • the heating cup 305 heats the cigarette inserted in the heating cup 305
  • the atomizing wire 204 in the atomizing assembly 2 enters a preheating state.
  • a smoker can smoke through a cigarette butt.
  • the air in the sensor airflow passage during the smoking process is also sucked away, thereby generating a negative pressure to the airflow sensor 5.
  • a heating wire in the atomizing assembly 2 is driven to work, i.e. e-liquid is atomized by the atomizing assembly.
  • the air enters the sensor airflow passage from a gap of a printed circuit board (PCB) circuit 8 at a bottom of the outer housing, and gets into the heating assembly 3.
  • the heating wire heats and atomizes the e-liquid to generate the smoke.
