  • the atomizing component is configured for generating aerosol from the tobacco liquid.
  • the power supply is adapted for providing the atomizing component power.
  • the disposable liquid supply is coupled to the atomizing component via screw threads. After the atomizing component is engaged with the disposable liquid supply, the liquid supply is pierced and the tobacco liquid flows out to the atomizing component for atomization.
  • a sealing element is arranged between the liquid supply and the atomizing component.
  • the atomizing component needs to be screwed several turns from a first position, where the liquid supply is first pierced, to a second position, where the liquid supply and the atomizing component are hermetically coupled. During this process, the tobacco liquid may leak via screw threads, rendering users experience unsatisfactory.
  • An exemplary atomizer includes a liquid supply and an atomizing component.
  • the liquid supply is configured for storing tobacco liquid.
  • the liquid supply has an open end and a sealing layer for sealing the open end.
  • the atomizing component is detachably coupled to the liquid supply by snap fit.
  • the atomizing component is configured for heating the tobacco liquid to vaporize.
  • the atomizing component includes a piercing element, a buffer chamber, and an atomizing unit.
  • the piercing element is configured for pricking the sealing layer, so that the tobacco liquid in the liquid chamber flows into the buffer chamber, when the atomizing component is engaged with the liquid supply.
  • the buffer chamber is configured for storing tobacco liquid flowed from the liquid chamber.
  • the atomizing unit is configured for absorbing the tobacco liquid from the buffer chamber, and generating aerosol from the tobacco liquid.
  • FIG. 1 is a cross-sectional view of an atomizer according to a first embodiment.
  • FIG. 2 is an exploded view of the atomizer of FIG. 1 .
  • FIG. 3 is a cross-sectional view of an atomizer according to a second embodiment.
  • FIG. 4 is an exploded view of the atomizer of FIG. 3 .
  • FIG. 5 is a cross-sectional view of the atomizer of FIG. 3 after assembled.
  • FIG. 6 is a cross-sectional view of an atomizer according to a third embodiment.
  • FIG. 7 is a partially perspective view of an atomizing component in the atomizer of FIG. 6 .
  • FIG. 8 is a side view of an electronic cigarette according to a fourth embodiment.
  • outside refers to a region that is beyond the outermost confines of a physical object.
  • inside indicates that at least a portion of a region is partially contained within a boundary formed by the object.
  • substantially is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder.
  • comprising when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
  • the atomizer 100 is configured (i.e., structured and arranged) for assembling with a power supply 200 to form an electronic cigarette.
  • the atomizer 100 includes a liquid supply 10 , a liquid chamber 12 in the liquid supply 10 , and an atomizing component 20 .
  • the liquid chamber 12 is configured for receiving tobacco liquid.
  • the atomizing component 20 is configured for generating aerosol from tobacco liquid.
  • the liquid supply 10 includes an opening 121 at one end.
  • a sealing layer 13 is provided at the opening 121 , and configured for sealing the tobacco liquid.
  • the atomizing component 20 includes a piercing element 22 adapted for piercing the sealing layer 13 .
  • the liquid supply 10 includes an air pipe 15 coaxially arranged with the liquid supply 10 .
  • the air pipe 15 and the liquid supply 10 are integrally formed, and made of an identical material.
  • the liquid chamber 12 is cooperatively defined between a housing of the liquid supply 10 and the air pipe 15 .
  • the atomizing component 20 includes a buffer chamber 25 , a sealing ring 23 , and an atomizing head 24 .
  • the buffer chamber 25 is configured for storing tobacco liquid flowed from the liquid chamber 12 .
  • the atomizing head 24 is in communication with the air pipe 15 .
  • the atomizing head 24 includes an atomizing unit 241 .
  • the atomizing component 20 is detachably connected with the liquid supply 10 by snap fit.
  • the piercing element 22 pricks the sealing layer 13 , so that the tobacco liquid in the liquid chamber 12 flows into the buffer chamber 25 for atomization. In this position, an open end of the liquid supply 10 is tightly pressed against the sealing ring 13 , thus avoiding liquid leakage.
  • the liquid supply 10 includes a mouthpiece 11 having an air outlet 111 .
  • the air outlet 111 is in communication with the air pipe 15 .
  • the mouthpiece 11 and the liquid supply 10 are integrally formed.
  • the liquid supply 10 includes a plug end 19 adapted for inserting into the atomizing component 20 .
  • the atomizing component 20 includes a first clip ring 21 configured for coupling with the plug end 19 .
  • the plug end 19 defines a first groove 14 in an outer surface.
  • the first clip ring 21 is engaged in the first groove 14 in use.
  • the air pipe 15 includes a stepped portion 151 formed on an inner surface
  • the atomizing head 24 includes a locking portion 242 .

  • the liquid supply 10 includes an annular chamber 16 for connecting with the atomizing component 20 .
  • the annular chamber 16 divides the housing of the liquid supply 10 into a first housing 18 and a second housing 17 .
  • the second housing 17 is inserted into the atomizing component 20 , and is clamped by the first clip ring 21 .
  • the connection end 26 is plugged into the annular chamber 16 , and is clamped by the second clip ring 40 .
  • the liquid supply 10 includes a plug end 19 for inserting into the atomizing component 20 .
  • the plug end 19 includes a plurality of L-shaped protrusions 191 on an exterior surface, and correspondingly, the atomizing component 20 defines a plurality of L-shaped grooves 28 on an interior surface. The grooves 28 match with the protrusions 191 .
  • the liquid supply 10 is rotated a predetermined angle so that the protrusions 191 engage in the grooves 28 .
  • the open end of the liquid supply 10 is tightly pressed against the sealing ring 13 , liquid leakage will not occur during the rotation of the predetermined angle.
  • the liquid supply 10 includes a check valve 50 in the open end. After the piercing element 22 pierces the sealing layer 13 , the piercing element 22 pushes the check valve 50 to an open state, so that the tobacco liquid flows to the buffer chamber 25 via the check valve 50 .
