And in FIG8 , the biasing element 21, such as a spring, is pressed by the user and is in a compressed state.
  • the biasing element 21 such as a spring
  • the biasing element 21 such as a spring, returns to the extended state through the elastic restoring force, thereby biasing the shielding element 60 and the operating element 20 toward the distal end 1200, so that the shielding element 60 abuts against the end cover 1200. Furthermore, through the elastic force of the biasing element 21, the shielding element 60 can be stably maintained in the open position after the user touches and presses in the open position.
  • the user can perform operations opposite to the above operations, proceeding from the state shown in FIG. 9 to FIG. 6 , thereby moving the shielding element 60 to the closed position and locking it, thereby preventing other people, especially minors, from obtaining the aerosol.
  • the user moves the shielding element 60 between the closed position and the open position by operating the element 20, thereby selectively opening or closing the communication port 124. Therefore, the above electronic atomization device 100 can selectively allow or prevent the user from obtaining aerosol.
  • the operating element 20 avoids the air inlet 121 in both the closed position and the open position; further, in the implementation, when the operating element 20 is in the closed position and the open position, the air inlet 121 is always open or uncovered.
  • an air flow channel can be formed from the air inlet 121 to the air outlet 113 when the user inhales.
  • the operating element 20 can be coupled to the housing 10 in a rotatable manner, such as by rotation, and can selectively close or open the communication port 124 by rotation.
  • the operating element is removably coupled to the housing 10, such as the operating element includes a detachable cover, which can close the communication port 124 when the operating element is coupled to the housing 10, and can open the communication port 124 when the operating element is detached from the housing 10.
  • FIG. 10 shows a schematic diagram of an airflow sensor 40 sensing an inhaled airflow in one embodiment; the airflow sensor 40 includes:
  • a deformable electrode film 41 is arranged close to the first side 410;
  • the electrode plate 42 is arranged close to the second side 420; and the deformable electrode membrane 41 and the electrode plate 42 are arranged relatively spaced apart along the axial direction of the airflow sensor 40.
  • the airflow sensor 40 determines the pressure difference between the first side 410 and the second side 420 based on the capacitance value between the deformable electrode membrane 41 and the electrode plate 42.
  • FIG. 11 shows the state of the airflow sensor 40 during suction; when the suction airflow flows through the first side 410, since the first side 410 is under negative pressure, and if the air pressure on the side of the deformable electrode film 41 facing the electrode plate 42 is connected to the outside atmosphere, the deformable electrode film 41 can bend or deform toward the first side 410 to the state shown in FIG. 11; of course, the greater the suction force of the user, the greater the negative pressure on the first side 410, and the greater the deformation of the deformable electrode film 41.
  • the change in the capacitance value defined between the deformable electrode film 41 and the electrode plate 42 is also greater; furthermore, the airflow sensor 40 determines the pressure difference between the first side 410 and the second side 420 based on the above change in capacitance value.
  • the connection between the second side 420 and the outside atmosphere is blocked or blocked by the shielding element 60, since the air pressure on the side of the deformable electrode film 41 facing the electrode plate 42 is isolated from the outside atmosphere, when the user sucks, the deformable electrode film 41 cannot deform in response to the negative pressure of suction.
  • the capacitance change between the deformable electrode membrane 41 and the electrode plate 42 cannot reach a responsive extent, and the airflow sensor 40 cannot be triggered in response to the user's inhalation.

Abstract

Dans la présente demande, un dispositif d'atomisation électronique est divulgué. Le dispositif d'atomisation électronique comprend : une cavité de stockage de liquide ; un élément chauffant ; une cellule de batterie ; un canal d'écoulement d'air ; un capteur d'écoulement d'air comprenant un premier côté et un second côté, le premier côté étant conçu pour être en communication d'écoulement d'air avec le canal d'écoulement d'air, et le second côté étant conçu pour être en communication avec l'atmosphère extérieure ; un orifice de communication pour fournir un canal pour faire communiquer le second côté avec l'atmosphère extérieure ; un élément de blocage mobile, au moyen duquel l'orifice de communication est sélectivement ouvert ou fermé ; un mécanisme de verrouillage, lorsque l'élément de blocage est situé dans une position fermée, le mécanisme de verrouillage étant dans un état de verrouillage de façon à empêcher l'élément de blocage d'être déplacé vers une position ouverte, et le mécanisme de verrouillage dans un état de déverrouillage permettant à l'élément de blocage d'être déplacé vers la position ouverte ; et un circuit, lequel commande la cellule de batterie pour qu'il fournisse de l'énergie électrique en fonction d'un résultat de détection du capteur d'écoulement d'air. Dans le dispositif d'atomisation électronique, l'élément de blocage est verrouillé dans la position fermée au moyen du mécanisme de verrouillage, empêchant ainsi l'élément de blocage, avant que celui-ci ne soit déverrouillé, d'être déplacé de la position fermée à la position ouverte de façon à obtenir un aérosol.
