  • a flange is provided on the inner wall of the battery shell 61 and / or the outer wall of the cartridge shell 51, so that after the cartridge 50 is inserted into the battery assembly 60, the cartridge shell 51 and the battery There is a gap between the shells 61, which connects the air inlet 517 and the outside atmosphere.
  • the structure of the battery assembly of the third embodiment is the same as that of the battery assembly 60 of the second embodiment, which will not be repeated here. Understandably, in other embodiments not shown, the cartridge 500 of the third embodiment may also be equipped with other power supply devices different from the battery assembly 60.
  • the mouthpiece 53 is used as a shield, and the smoke outlet 532 is used as a communication port.
  • the user cannot directly contact the seal 52, which can prevent children from arbitrarily removing the seal 52, and the adult user can pass through the smoke outlet 532
  • the liquid injection needle 70 is inserted into the seal 52 to perform liquid injection.
  • the base 541 is used as a shield. The base 541 is connected to the cartridge shell 51 and is not detachable to prevent children from contacting the sealing plug 542. However, the sealing plug 542 is arbitrarily removed to contact the liquid smoke.
  • the sealing member (the seal 52 in the second embodiment and the sealing plug 542 in the third embodiment) is located between the shield and the cartridge housing 51, so
  • the shield constitutes part of the outer contour of the cartridge 50, 500. Therefore, the sealing member is shielded by the shield so that children cannot contact the sealing member arbitrarily, and the clamping function of the sealing member between the shield and the cartridge housing 51 It will not sway arbitrarily and prevent the sealing member from being driven when the injection needle 70 is pulled out, which may cause liquid leakage.
  • the necessary components of the cigarette cartridges 50 and 500 such as the cigarette holder 51 and the base 541, are used as shields, so that one component has multiple functions, and the structural arrangement is more reasonable.
  • the sealing plug 542 is used for liquid injection.
  • the sensing notch 5414 is used as a communication port, and the injection needle 70 penetrates the sealing plug 542 through the sensing notch 5414, and then extends into the liquid storage chamber 510 to inject liquid; in another embodiment
  • the air intake hole 517 is opened on the base 541.
  • the air intake cavity 513 and the air intake port 535 can be omitted, and the air intake hole 517 communicates with the air gap 5420,
  • the air inlet hole 517 is used as a communication port.
  • the liquid injection needle 70 passes through the air inlet hole 517 and the air gap 5420 in order and then pierces the sealing plug 542, and then extends into the liquid storage chamber 510 for liquid injection.

Abstract

La présente invention se rapporte au domaine technique de la charge, et concerne ainsi un circuit d'indication d'état de charge et un dispositif électronique. Le circuit d'indication d'état de charge comprend : une première diode électroluminescente couleur, une seconde diode électroluminescente couleur, une diode, une première résistance et une seconde résistance, l'anode de la première diode électroluminescente couleur D5 étant électriquement connectée à une alimentation électrique au moyen d'une première résistance R15, et la cathode de la première diode électroluminescente couleur D5 étant connectée électriquement à une extrémité d'indication d'état de charge 11 d'une puce de charge U3 ; une extrémité de la seconde résistance R5 étant électriquement connectée à l'alimentation électrique, et l'autre extrémité de la seconde résistance R5 étant électriquement connectée à l'anode de la diode D3 ; la cathode de la diode D3 étant électriquement connectée à l'extrémité d'indication d'état de charge 11 ; l'autre extrémité de la seconde résistance R5 étant également connectée électriquement à l'anode de la seconde diode électroluminescente couleur D4, et la cathode de la seconde diode électroluminescente couleur D4 étant mise à la terre. Ainsi, le problème rencontré par un témoin lumineux vert dans des dispositifs électroniques existants ayant des difficultés à indiquer précisément si un ensemble batterie est complètement chargé ou non est résolu, et l'effet d'une indication précise de l'état de charge d'un ensemble batterie est obtenu.
