Many specific details are set forth in the following description to provide a thorough understanding of this application. For illustrative purposes, specific structures and details are presented in the description to provide a complete understanding of the embodiments. Those skilled in the art will readily recognize that some features may be omitted in different circumstances, or may be replaced by their components, materials, or methods. In some cases, to make the described embodiments clear, well-known features are not shown or described in the specification; for those skilled in the art, describing these related operations in detail is not necessary.

[0035] The electronic atomizer described in this application can be used to heat and atomize liquid aerosol generating matrix such as e-liquid or liquid medicine to form aerosol, which is then inhaled by the user.

[0036] This application provides an electronic atomizer, which includes a liquid storage chamber and an atomizing assembly. The atomizing assembly includes an atomizing base, an atomizing tube, and a heating element. The atomizing tube is assembled with the atomizing base, and the heating element is assembled inside the atomizing tube. The atomizing tube is in fluid communication with the liquid storage chamber. When a negative pressure is created in the atomizing assembly due to the user's inhalation, the liquid stored in the liquid storage chamber flows to the atomizing assembly under the negative pressure and is heated by the heating element of the atomizing assembly to form an aerosol.

[0037] refer to Figures 1 to 6 As shown, an electronic atomizer 1 includes a liquid storage component 10, a container 20, a battery 40, and an atomizing component 50. The liquid storage component 10 can be removed from one end of the container 20, while the battery 40 and the atomizing component 50 are assembled on a frame 30 to form a whole and installed inside the container 20.

[0038] In some embodiments, the liquid storage assembly 10 includes a housing, the interior of which defines a first liquid storage chamber 100 for the electronic atomizer 1, in which the atomizing liquid is stored. The housing is provided with an outlet 11 and a slot 13. The outlet 11 is used to output the atomizing liquid to the atomizing assembly 50, and the slot 13 is used to engage with any one of the container 20, the atomizing assembly 50, or the frame 30.

[0039] refer to Figure 2 and Figure 3 As shown, the liquid storage assembly 10 is inserted into the container 20 in the longitudinal direction. In some embodiments, the housing of the liquid storage assembly 10 is at least partially inserted into the container 20, and the housing is connected to the inner wall of the container 20 or the atomizing assembly 50 to enable the first liquid storage chamber 100 to deliver atomized liquid to the atomizing assembly 50.

[0040] refer to Figure 3As shown, a seal 12 is also provided at the liquid outlet 11. The seal 12 can be removed or broken, for example, a sealing plug or a sealing membrane. When the liquid storage assembly 10 is not in use, the seal 12 blocks the liquid outlet 11; when the liquid storage assembly 10 is in use, the seal 12 is pushed into the first liquid storage chamber 100 by an external object, or pulled out by an external force, or punctured by an external object.

[0041] In some embodiments, in addition to the first liquid storage chamber 100, the housing also has a receiving portion for insertion into the container 20. The receiving portion extends from the wall of the housing in a direction away from the first liquid storage chamber 100 and surrounds a receiving groove. The receiving groove has a first inner diameter section close to the first liquid storage chamber 100 and a second inner diameter section away from the first liquid storage chamber 100. The inner diameter of the first inner diameter section is smaller than that of the second inner diameter section. The slot 13 is provided on the groove wall of the second inner diameter section.

[0042] In some embodiments, the housing is further provided with an air passage 14, which has an air inlet and an air outlet. (Reference) Figure 4 As shown, the air passage 14 penetrates the housing, forming an air inlet on the same side as the liquid outlet 11 and an air outlet on the other side. The gas generated by the atomizing component 50 heating the atomizing liquid enters through the air inlet of the air passage 14 and is discharged through the air outlet.

[0043] The container 20 includes a first end and a second end in the longitudinal direction, forming a space between the first end and the second end for receiving the liquid storage assembly 10, the atomizing assembly 50, and the battery 40. In some embodiments, the container 20 is configured as a hollow structure, with the first end having an opening for receiving the liquid storage assembly 10 for insertion, and the atomizing assembly 50 and the battery 40 being mounted on the side away from the first end.

[0044] In some embodiments, an air gap is provided between the inner wall of the container 20 and the outer wall of the shell, and the air inlet of the atomizing component 50 is connected to the outside atmosphere outside the container 20 through the air gap.

[0045] See Figure 4 and Figure 5 A frame 30 is installed inside the container 20. The frame 30 includes an atomizing base 31 facing a first end and a battery holder 32 facing a second end. The atomizing component 50 is mounted on the atomizing base 31, and the battery is mounted on the battery holder 32. The frame 30 secures the atomizing component 50 and the battery 40 inside the container 20.

[0046] In some embodiments, the frame 30 divides the internal space of the container 20 into a first cavity on the same side as the first end and a second cavity on the same side as the second end. The atomizer seat 31 is disposed in the first cavity, and the battery holder 32 is disposed in the second cavity. A portion of the outer wall of the frame 30 is sealed to the inner wall of the container 20 to isolate the two cavities from the periphery of the frame 30.

[0047] In some embodiments, the atomizing seat 31 has a sidewall spaced apart from the inner wall of the container 20, and the sidewall surrounds a mounting groove 314 for receiving the atomizing assembly 50.

[0048] In some embodiments, the mounting groove 314 is a countersunk hole, with the large hole facing the liquid storage chamber and the small hole facing away from the large hole and penetrating through the atomizing seat 31, and the small hole connecting to the outside atmosphere.

[0049] In some embodiments, the liquid storage assembly 10 is snapped into the atomizing seat 31. For example, a buckle 3120 is provided on the outer side of the sidewall for detachably snapping into the slot 13.

[0050] In some embodiments, two slots 13 are symmetrically provided on the housing, and two buckles 3120 are symmetrically provided on the outer periphery of the second outer diameter section 312. When the buckles 3120 engage with the slots 13, the first outer diameter section 311 and the first inner diameter section are assembled to a preset position and a sealed connection is achieved between the housing and the atomizing seat 31.

[0051] In some embodiments, the buckle head of the latch 3120 is arc-shaped and protrudes outward. The arc shape can be configured as a semi-circular hemisphere or an axially sectional semi-cylindrical shape. The arc shape facilitates the buckle head sliding into and out of the latch slot 13. Furthermore, the number of latches 3120 and latch slots 13 is consistent, generally with two latch slots 13 and two latches 3120.

[0052] In some embodiments, the housing of the liquid storage assembly 10 can be connected to the inner wall of the container 20, i.e., the snap fastener 3120 is disposed on the inner wall of the container 20. During assembly, the housing is inserted from the first end of the container 20, and the housing covers the mounting groove 314 of the atomizing seat 31. The snap fastener 3120 located on the inner wall of the container 20 engages with the slot 13 from the outer surface of the housing. At the same time, the snap fastener 3120 abuts against the slot 13 so that the inner wall of the receiving part is tightly fitted and sealed to the side wall of the atomizing seat 31. The housing and the atomizing seat 31 define the second liquid storage chamber 300 of the atomizer.

[0053] When the liquid storage component 10 is inserted into the first end and connected to the atomizing base 31, the buckle 3120 engages with the slot 13, and the housing closes the mounting slot 314 to define the second liquid storage chamber 300 of the electronic atomizer 1, and the second liquid storage chamber 300 is in fluid communication with the first liquid storage chamber 100.

[0054] In some embodiments, the second liquid storage chamber 300 is provided with a liquid storage medium 316. The liquid storage medium 316 is generally a liquid storage cotton or a ceramic body with a porous or microporous structure. Even after the shell is separated from the atomizing seat 31, the atomizing liquid can remain still under the constraint of the liquid storage medium.

[0055] refer to Figure 6As shown, the atomizing seat 31 has a first outer diameter section 311 and a second outer diameter section 312 arranged longitudinally. The first outer diameter section 311 is used to insert into the first inner diameter section of the aforementioned receiving part and is sealed to the inner wall of the first inner diameter section. The second outer diameter section 312 is sleeved with the second inner diameter section. The sealing fit between the first outer diameter section 311 and the first inner diameter section is used to cooperate with the mating seal between the housing and the atomizing seat 31 to achieve the closure of the second liquid storage chamber 300.

[0056] In some embodiments, the outer periphery of the first outer diameter section 311 is provided with an annular groove, and a sealing ring 313 is provided in the groove. The first outer diameter section 311 is press-fitted with the inner wall of the housing 10 receiving part through the sealing ring 313, so as to achieve the sealing of the mounting groove 314 by the receiving part and the atomizing seat 31.

[0057] In some embodiments, the atomizing seat 31 is provided with an actuating part 315 disposed opposite to the liquid outlet 11. After the latch 3120 engages with the slot 13, the actuating part 315 breaks the seal 12 or pushes the seal 12 away from the liquid outlet 11, so as to realize the liquid communication between the first liquid storage chamber 100 and the second liquid storage chamber 300.

[0058] refer to Figure 6 As shown, the atomizing seat 31 has a top surface connected to its sidewall, a mounting hole is formed on the top surface, and the edge portion of the mounting hole is provided with symmetrically arranged and longitudinally protruding actuating portions 315, which protrude in a columnar shape from the edge of the mounting hole. In some embodiments, the actuating portions 315 may be flat, cylindrical, rhomboid, or triangular, etc. The cross-sectional shape of the actuating portions 315 does not limit the actuating portions 315 from abutting the seal 12 and causing the seal 12 to disengage from the liquid outlet 11 or puncture the seal 12.

[0059] In some embodiments, the frame 30 is provided with an air guide hole that communicates with the small hole on the mounting groove 314. The air guide hole is connected to the outside atmosphere of the container 20, and the air inlet end of the atomizing component 50 is connected to the outside atmosphere through the air guide hole.

[0060] The battery holder 32 and the atomizer seat 31 are connected to form a frame 30. In some embodiments, the battery holder 32 and the atomizer seat 31 are integrally formed. In some embodiments, the battery holder 32 and the atomizer seat 31 are detachably connected. Regardless of the connection method between the battery holder 32 and the atomizer seat 31, the outer wall of at least one of the battery holder 32 and the atomizer seat 31 is sealed to the inner wall of the container 20, thereby isolating the first cavity from the second cavity. In some embodiments, the battery holder 32 has a recessed groove in which electrodes are provided, and the battery 40 is assembled in the groove. The battery 40 is electrically connected to the atomizer assembly 50 through the electrodes.

[0061] In some embodiments, the side of the battery holder 32 near the second end forms an end cap 33 of the container 20, which is used to close the second end.

[0062] In some embodiments, there is a gap between the battery holder 32 and the inner wall of the container 20, the gap being connected to the air inlet of the atomizing assembly 50, and the end cap 33 is provided with an air inlet hole communicating with the outside. The air inlet hole and the air guide hole are in gas communication, and the outside airflow enters the air inlet of the atomizing assembly 50 in sequence through the air inlet hole and the air guide hole.

[0063] Understandably, the atomizing assembly 50 includes an atomizing tube 51 and a heating element. (See reference) Figure 6 As shown, one end of the atomizing tube 51 is fitted into the small hole of the mounting groove 314. The interior of the atomizing tube 51 is connected to the external atmosphere. The outer wall of the atomizing tube 51 and the inner wall of the large hole of the mounting groove 314 are spaced apart and define the fluid space. The atomizing tube 51 is provided with a fluid channel that communicates with the fluid space. The heating element is fixed inside the atomizing tube 51 and electrically connected to the battery 40 through electrodes.

[0064] In some embodiments, the air inlet end of the atomizing tube 51 can be connected to the outside atmosphere through the air gap in the above embodiments.

[0065] In some embodiments, the air inlet end of the atomizing tube 51 can be connected to the outside atmosphere through the air guide hole and air inlet hole in the above embodiments.

[0066] In some embodiments, the liquid storage medium is wrapped around the outer wall of the atomizing tube 51. After the fluid channel is connected to the second liquid storage chamber 300, the atomized liquid released by the liquid storage medium enters the atomizing tube 51 through the fluid channel and comes into contact with the heating element 52.
