The atomization core closes the flow channel, and the smoke oil flows into the flow channel and penetrates into the atomization core for atomization. The seal is integrally formed on the seal, including a first sealing portion sealing the accommodating end of the seal, a third sealing portion formed on the closed end, and a sealing structure sealing the notch and the airway, and the seal is an integral structure, which is connected to the outside by extending.

[0042] Embodiment 1

[0043] See also Figures 1 to 13 As shown, the atomizing device of the present application includes a shell 10 provided with an air pipe 13 and a cavity 12, a closing body 20 inserted into the cavity 12 to close the liquid storage cavity 121, an atomizing core 30 installed in the closing body, and a base 50 at least partially inserted into the cavity 12 and fixed to the shell 10.

[0044] The housing 10 includes an outer shell 11, a cavity 12 located in the outer shell 11, and an air pipe 13 extending downward from the top of the outer shell into the cavity 12. The air pipe 13 includes a tube body 131 extending from the top of the outer shell 11 into the cavity 12, an air hole 133 penetrating the tube body 131 from top to bottom, and an insertion portion 132 formed at the bottom of the tube body 131. The outer diameter of the insertion portion 132 is smaller than the outer diameter of the tube body 131. The cavity 12 includes a liquid storage cavity 121 located in the outer shell 11 and located at the periphery of the air pipe 13, and a closed cavity 122 located below the liquid storage cavity 121. The separation boundary between the liquid storage cavity 121 and the closed cavity 122 is not strictly limited, and the liquid storage cavity 121 can also extend into the closed body 20. A step structure is formed at the junction of the liquid storage cavity 121 and the closed cavity 122 to limit the highest position of the closed body 20. Preferably, the air pipe 13 is located in the middle of the liquid storage cavity 121 ; in a specific implementation, the air pipe 13 may also be arranged on one side or both sides of the liquid storage cavity 121 .

[0045] Key References Figure 7 , Figure 8As shown, the atomizer core 30 includes a porous body 31 for liquid infiltration, and the porous body 31 includes a first surface 32 facing the liquid storage chamber 121 and connected to the liquid storage chamber 121, a second surface 33 opposite to the first surface 32, and a through groove 34 formed by being recessed downward from the first surface 32. The through groove 34 is formed by horizontally penetrating the porous body 31 and opening at the upper end. The through groove 34 is formed by being recessed downward from the middle of the first surface 32. The longitudinal sides of the first surface 32 are used for upward support. The through groove 34 is conducive to reducing the thickness of the porous body 31 to reduce the distance of liquid infiltration. Thus, it is convenient for the atomized liquid to penetrate to one side of the second surface 33. The atomizer core 30 also includes a heating element 36 provided on the second surface of the porous body 31, and the heating element 36 includes a heating element 361 attached to the second surface and a contact portion 362 connecting the two ends of the heating element 361. The contact portion 362 is used for contact transmission current. The heating element 361 can be a resistance wire or a heating mesh structure or a heating porous body. The heating element 36 generates heat to atomize the atomized liquid in the porous body 41 , thereby generating atomized gas on the second surface 33 .

[0046] Key References Figures 2 to 6 , Fig.12 , Fig.13 As shown, the closed body 20 includes a support body 201 formed by plastic injection molding and a sealing member 60 integrally formed on the support body 201. The closed body 20 includes a closed end 21, a receiving portion 22 and a supporting end 23 from top to bottom. The closed end 21, the receiving portion 22 and the supporting end 23 are an integral structure, which are formed by the support body 201 and the sealing member 60. The closed end 21 of the closed body 20 is provided with flow channels 24 on both sides in the lateral direction downward, the receiving portion 22 is provided with a receiving cavity 27 connected to the flow channel 24, and the atomizing cavity 80 located below the receiving cavity 27 is provided inside the supporting end 23. The flow channel 24, the accommodating chamber 27 and the atomizing chamber 80 are connected to each other before the atomizing core 30 is installed. After the atomizing core 30 is installed in the accommodating chamber 27, the connection between the flow channel 24 and the atomizing chamber 80 is blocked. The flow channel 24 is connected to the first surface of the atomizing core 30, and the atomizing chamber 80 is connected to the second surface 33 of the atomizing core.

[0047] The accommodating cavity 27 is close to the flow channel 24 and is formed with a support step 26 protruding toward the accommodating cavity 27. The support step 26 is preferably an annular structure protruding to the accommodating cavity 27 for limiting the first surface of the atomizer core 30. The support step 26 may also be a non-annular protruding structure, and can be protruding on both sides in the longitudinal direction.

[0048] The closed body 20 also includes an air passage 25 opened from the top downward, and the air passage 25 includes a docking air passage 251 penetrating the closed end 21 in the vertical direction, a longitudinal air passage 252 penetrating the closed end 21 in the longitudinal direction, and an outer air passage 253 extending downward from the end edge of the longitudinal air passage 252 along the longitudinal outer wall of the closed end 21, and a connecting window 254 connecting the outer air passage 253 and the atomizing chamber 80. The air passage 25 and the flow passage 24 are sealed independently of each other. The connecting window 254 is opened on the longitudinal outer wall of the abutting end 23. Positioning structures 28 are formed by extending downward on both sides of the abutting end 23 of the closed body 20.

[0049] The support body 201 of the enclosure 20 is made of hard plastic material as a skeleton support structure, and the seal 60 is made of flexible material as a sealing element wrapped outside the support body 201, such as food-grade silica gel. The manufacturing method can be to first injection mold the support body 201, and then form the seal 60 by in-mold molding the support body 201, and the seal 60 has a certain shrinkage elasticity. The flow channel 24 and the inner wall surface of the accommodating chamber 27 of the enclosure 20 are fully covered by the seal 60, which can effectively enhance the overall air tightness of the flow channel 24 and the accommodating chamber 27 and reduce the leakage of the atomized liquid. In the specific implementation, the seal 60 fully wraps the inner wall surface of the flow channel 24, the accommodating chamber 27 and the atomizing chamber 80 to form a wrapped wall surface 61.

[0050] The sealing member 60 further includes a first sealing clamping portion 62 extending from the top of the wrapping wall 61 to cover the top surface and at least part of the outer surface of the closed end 21, a second sealing clamping portion 63 extending from the top of the wrapping wall 61 to cover the top of the air channel 25 and at least part of the inner wall of the air channel 25, and a third sealing clamping portion 64 extending from the bottom of the wrapping wall 61 to the outer wall of the abutting end 23. The wrapping wall 61 forms an atomizing core wrapping portion 66 clamped between the outer wall of the atomizing core 30 and the inner wall of the atomizing core 30 on the inner wall of the accommodating cavity 27, and the sealing member 61 is wrapped on the lower side of the abutting step 26 to form an elastic supporting layer 67 abutting on the first surface 32 of the atomizing core 30, and the elastic supporting layer 67 has a certain thickness and good elasticity.

[0051] In order to adapt to the structure of the atomizer core 30 in this embodiment, the atomizer core wrapping portion 66 is further formed with sealing ends 65 on both lateral sides thereof, which are pressed against the lateral ends of the through slot 34 of the atomizer core 30. The sealing ends 65 are pressed against the lateral ends of the through slot 34 to achieve sealing of the lateral ends of the through slot 34. The thickness of the sealing ends 65 is greater than the thickness of the atomizer core wrapping portion 66. The connecting window 254 spans the atomizer cavity 80 and the accommodating cavity 27, so that the longitudinal sides of the atomizer core 30 are at least partially exposed in the connecting window 254 to increase the outlet of the atomized gas.

[0052] Key References Fig.13 As shown, the top surfaces of both sides of the atomizer core 30 are covered by the elastic support layer 67 of the sealing member 60, so that the first surface 32 of the atomizer core 30 is completely covered without causing liquid seepage. At the same time, the elastic support layer 67 prevents the atomizer core 30 from being over-inserted and provides downward support. The outer peripheral surface of the atomizer core 30 is wrapped in the atomizer core wrapping portion 66 to achieve sealing and fixing.

[0053] In one embodiment, at least part of the lower surface of the elastic support layer 67 is located above the through groove 34, that is, the elastic support layer 67 extends to the top of the through groove 34 along the longitudinal direction, so that the first surface 32 adjacent to the side edge of the through groove 34 is also covered by the elastic support layer 67. When the atomizer core 30 is squeezed upward, the elastic support layer 67 turns downward and wraps part of the inner wall surface of the through groove 34. In this way, the first surface 32 of the atomizer core 30 can be subjected to force as a whole to ensure that it will not be squeezed and cracked.

[0054] In one embodiment, the atomizing chamber 80 is not necessarily disposed in the abutting end 23 of the enclosing body 20, but may be disposed at the lower side of the enclosing body 20, or the abutting end 23 may be a part of the atomizing chamber 80. That is, the atomizing chamber 80 is located between the atomizing core 30 and the base 50.

[0055] See also Figures 9 to 13As shown, the base 50 is integrally formed with a conductive terminal 55, and the base 50 includes a base body 51, an outer wall 52 extending upward from the outer circumference of the base body 51, buckle parts 53 formed on both sides of the outer wall 52, and an air inlet 54 formed through the base 50. The base 51 includes a bottom wall 511, a reinforcing rib 513 formed on the bottom wall 511, and a wrapping reinforcing part 512 extending upward from the bottom wall 511 and wrapping a part of the conductive terminal 55. The outer wall 52 and the bottom wall 511 are enclosed to form an enclosed space 522 with an open upper end, and the air inlet 54 is formed by a convex column with a middle hole extending upward from the bottom wall 511, and a plurality of microporous structures are opened at the top of the convex column, so that the air inlet 54 is higher than the bottom wall 511, so as to prevent the atomized liquid from leaking easily and being retained in the enclosed space 522. The two transverse ends of the peripheral wall 52 are formed with alignment holes 521 corresponding to the positioning structure 28 of the enclosure 20. The positioning structure 28 is correspondingly inserted into the alignment holes 521 and provides support force to the enclosure 20.

[0056] The conductive terminal 55 includes a contact plate 551 which is plate-shaped and exposed on the lower surface of the bottom wall 511, a folding portion 552 formed by reverse bending from the inner side of the contact plate 551, a sheet 553 formed by extending from the folding portion 552 parallel to the contact plate 551 and located above the contact plate 551, a contact strip 554 formed by vertically bending and extending upward from one side of the sheet 553, an embedded hook 555 formed by bending upward from the outer side of the contact plate 551, a connecting portion 556 formed on one longitudinal side of the sheet 553, and a molding hole 557 formed through the sheet 553. The contact plate 551, the folding portion 552 and the sheet 553 are molded and embedded in the bottom wall 511, and the connecting portion 556 extends from the outer side of the peripheral wall 52 or the longitudinal side of the bottom wall 511 to the outside to connect the material strip and cut the material strip after injection molding or assembly. The embedded hook portion 555 on the transverse outer side of the contact plate body 551 is embedded in the bottom wall 511. At the same time, the embedded hook portion 555 is arranged opposite to the folding portion 552 to prevent the contact plate body 551 from cracking and generating a gap. The contact strip 554 is a longitudinal structure extending upward and includes a wrapped reinforcement portion 5541 formed by vertically bending and extending upward from one end of the sheet body 553 and an exposed contact 5542 formed by continuing to extend upward from the wrapped reinforcement portion 5541. The contact strip 554 and the connecting portion 556 are located on opposite sides of the longitudinal direction. In a specific implementation, the contact strip 554 can also be formed by vertically bending and extending upward from one end of the sheet body 553 adjacent to the connecting portion 556.

[0057] The wrapped reinforcement portion 5541 is wrapped in the wrapped reinforcement portion 512 to increase the strength of the lower side of the contact strip 554, so that the contact strip 554 will not be bent and damaged when it is pressed upward to contact the contact portion 362 of the atomizer core 30. The outer dimension of the wrapped reinforcement portion 512 extending upward from the bottom wall 511 gradually decreases, so that the wrapped reinforcement portion 512 has a conical structure. In a specific implementation, the wrapped reinforcement portion 512 can also be a cylindrical structure, etc., and the size can be kept consistent, as long as the strength of the wrapped reinforcement portion 5541 is strengthened. The molding hole 557 is filled with plastic material after injection molding to enhance the holding force of the base 50 on the contact plate body 551 and the sheet body 553.

[0058] After the conductive terminal 55 is injection molded in the base 50, the contact strip 554 has no elastic force or has very weak elastic force. If it is squeezed hard, it will cause the contact strip 554 to bend and fail. The exposed contact 5542 needs to elastically contact the contact part 362 at the bottom of the atomizer core 30 upward to achieve conductive connection.

[0059] The sealing member 60 of the present application is provided with an elastic supporting layer 67 at the top periphery of the accommodating cavity 27, and the atomizer core 30 is provided with a through groove 34 downwardly in the transverse direction, so that the first surface 32 of the top of the longitudinal outer wall of the through groove 34 is completely placed under the elastic supporting layer 67, and the elastic supporting layer 67 is at least partially located above the through groove 34, so that when the elastic supporting layer 67 is squeezed, the first surface of the atomizer core 30 is subjected to stress as a whole and will not be easily broken.

[0060] The atomizer device of the present application utilizes the elastic support layer 67 of the closure body 20 located at the top of the accommodating cavity 27 to abut against the first surface 32 of the atomizer core 30, and the top of the contact strip 554 of the conductive terminal 55 of the base 50 presses the contact portion 362 on the second surface 33 of the atomizer core 30 upward, and provides elastic deformation force by squeezing the elastic support layer 67 without the need for the contact strip 554 to provide elastic force, so that the contact effect is better, and the technical problem that after the existing one-piece injection-molded conductive terminal 55 is provided with an elastic contact arm, the elastic force is insufficient, which easily leads to poor contact.

[0061] The flow channel 24 and the inner wall surface of the accommodating chamber 27 of the closed body 20 of the present application are fully wrapped. When the sealing member 60 is formed, the material of the sealing member 60 flows and fills along the inner wall surfaces of the flow channel 24 and the accommodating chamber 27, and at the same time, the top of the closed end 21 is fully covered to form an integrated sealing structure, thereby achieving better sealing performance. At the same time, in the presence of the abutting end 23, the inner wall surface of the atomizing chamber 80 in the abutting end 23 is completely wrapped, thereby further achieving the sealing between the atomized liquid in the flow channel 24 and the air channel 25, thereby solving the problem in the prior art that the sealing member 60 and the bracket body 201 are partially combined on the inner wall surface, but there is still a bonding surface area, thereby avoiding the bonding area from cracking and causing an airtightness problem. By adopting this solution, when the sealing member 60 is not tightly combined with the bracket body 201, a good airtight seal can still be maintained.

[0062] Embodiment 2

[0063] See also Figures 14 to 17 As shown, the atomizer core of this embodiment is different from the atomizer core of the first embodiment. The atomizer core 40 of this embodiment includes a porous body 41, a first surface 42 and a second surface 43 located at the upper and lower sides of the porous body 41, a through hole 44 that passes through the porous body 41 horizontally, and a heating element 45 provided on the second surface 43. The heating element 45 is consistent with the heating element 36 in the first embodiment, and will not be repeated here.

[0064] The through hole 44 is surrounded by the upper and lower sides and the longitudinal sides except for the two lateral sides that are connected to the outside. The first surface 42 completely covers the upper side of the through hole 44, and the atomized liquid enters the through hole 44 only through the connecting openings on the two lateral sides of the through hole 44. The atomized liquid penetrates downward from the through hole 44 into the porous body 41, and after being heated by the heating element 45, the atomized liquid is atomized to generate atomized gas from the second surface 43.

[0065] The abutting step 26 of the closure body 20 is formed protruding from the top of the two longitudinal sides of the accommodating chamber 27, and the two lateral sides of the accommodating chamber 27 are downwardly provided with connecting grooves 29 connecting the flow channel 24 and the two lateral sides of the through hole 44. The atomized liquid flows from the flow channel 24 into the connecting grooves 29 and into the through hole 44. Both lateral ends of the through hole 44 are open to effectively ensure the pressure-free flow of the atomized liquid. The first surface 42 of the atomizing core 40 is abutted against the elastic supporting layer 67 under the abutting step 26 for limiting.

[0066] Please continue reading Fig.18As shown, another implementation structure of the second embodiment, that is, the top of the atomizer core 40 is supported on the bottom wall of the longitudinal air channel 252. At this time, there is no need to set an abutting step 26 in the accommodating cavity 27, or only abutting steps 26 parallel to the longitudinal air channel 252 need to be set at some positions. At the same time, the thickness of the first surface 42 of the porous body 41 can be increased to increase the strength of the atomizer core 40.

[0067] The atomizing device of the present application forms a through hole 44 through the porous body 41 of the atomizing core 40 in the lateral direction, and then provides connecting grooves 29 connecting the through hole 44 and the flow channel 24 on both lateral sides of the accommodating cavity 27 of the closing body 20, so that the atomized liquid flows into the through hole 44 of the atomizing core 40 from both lateral sides of the flow channel 24, thereby reducing the distance for the atomized liquid to penetrate downward, while taking into account the strength of the atomizing core 40 to avoid being squeezed and cracked.

[0068] The present application also provides an electronic cigarette, including the atomization device and a cigarette rod (not shown), wherein the cigarette rod includes a battery assembly, a control unit, and a connection terminal of a contact plate 551 electrically connected to a conductive terminal 55 of the atomization device, and the atomization device heats the atomization core 30, 40 through the electric energy output by the cigarette rod, so that the atomization core 30, 40 is atomized to generate atomized gas, and external gas enters the atomization chamber 80 through the air inlet hole 54, driving the generated atomized gas to enter the air pipe 13 from the airway 25 to be inhaled by the user.

[0069] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
