  • the specific value of the threshold pressure can be 30 Pa, 40 Pa, 70 Pa, or the like.
  • the baffle 310 can quickly open the air inlet 410, and the user does not need to pump vigorously to form a higher air pressure difference, preventing the suction force If it is too small to cause the blocking piece 310 to be separated from the base 200, the feeling of jamming or breaking can improve the response sensitivity of the atomizer 10 to the user's suction.
  • the maximum distance H between the baffle 310 and the contact surface 212 is 0.3 mm to 1.5 mm, and the specific value of the maximum distance H can be 0.3 mm, 1 mm, or 1.5 mm.
  • the gas of the air inlet 410 can enter the air flow channel 400 above the baffle 310 through the space corresponding to the maximum distance H, ensuring that there is enough outside air to carry smoke for the user to inhale. The user's requirements for different suction volumes.

Abstract

Est divulgué un atomiseur (10) comprenant : un canal d'écoulement de gaz (400) comprenant une entrée de gaz (410) et une sortie de gaz (420) ; un noyau d'atomisation (100) au moins partiellement situé à l'intérieur du canal d'écoulement de gaz (400) ; une base (200), l'entrée de gaz (410) traversant la base (200) ; et un clapet de retenue (300) comprenant un clapet relié élastiquement à la base (200), le clapet (310) ayant un état fermé et un état ouvert, le clapet (310) étant normalement dans l'état fermé dans lequel le clapet (310) recouvre l'entrée de gaz (410), et lorsqu'une action d'aspiration se produit au niveau de la sortie de gaz (420), le clapet (310) étant dans l'état ouvert dans lequel un flux de gaz peut passer. La base (200) a une surface supérieure (210) et le clapet a une surface inférieure (311). Lorsque le clapet (310) est dans l'état fermé, la surface supérieure (210) est opposée à la surface inférieure (311). La surface supérieure (210) et/ou la surface inférieure (311) réduisent la zone de contact entre le clapet (310) et la base (200) au moyen de certaines saillies ou de certains évidements se trouvant sur lesdites surfaces.
