The abutting end 23 of the closing body 20 extends downwards on both lateral sides to form a positioning structure 28 .

The support body 201 of the enclosure 20 is used as a skeleton support structure and is made of hard plastic material, and the sealing member 60 is used as a sealing element wrapped outside the support body 201 and is made of a flexible material, such as food grade silica gel, etc. material. The manufacturing method may be that the bracket body 201 is injection-molded first, and then the bracket body 201 is in-molded to form the sealing member 60, and the sealing member 60 has a certain shrinkage elasticity. The flow channel 24 of the closed body 20 and the inner wall surface of the accommodating cavity 27 are fully covered by the sealing member 60, which can effectively enhance the overall airtightness of the flow channel 24 and the accommodating cavity 27, and reduce the airtightness of the atomized liquid.

The wrapped reinforcing part 5541 is wrapped in the wrapped reinforcing part 512 to increase the strength of the lower side of the contact strip 554, so that the contact strip 554 does not touch the contact part 362 of the atomizing core 30 upwards. damaged by bending. The external dimension of the wrapping reinforcing part 512 extending upward from the bottom wall 511 decreases gradually, so that the wrapping reinforcing part 512 has a tapered structure. In actual implementation, the wrapping reinforcing part 512 can also be a cylindrical structure, etc., and the size can be kept consistent, as long as the strength of the wrapped reinforcing part 5541 can be strengthened. The forming hole 557 is filled with plastic material after injection molding to enhance the holding force of the base 51 to the contact plate 551 and the sheet 553 .

After the conductive terminals 55 are injection-molded in the base 50 , the contact strips 55 have no elastic force or have extremely weak elastic force, and hard extrusion will cause the contact strips 55 to bend and fail. The exposed contact 5542 needs to elastically contact upwards to the contact part 362 at the bottom of the atomizing core 30 to achieve a conductive connection.

The atomizing device of the present application utilizes the elastic support layer 67 of the closing body 20 at the top of the accommodating cavity 27 against the first surface 32 of the atomizing core 30 , and the contact of the conductive terminal 55 of the base 50 The top of the strip 554 presses upwards the contact portion 362 on the second surface 33 of the atomizing core 30, and provides elastic deformation force by pressing the elastic supporting layer 67 without the elastic force provided by the contact strip 554, The contact effect is better, and the technical problem that the elastic contact arm is provided on the conventional integrated injection-molded conductive terminal 55 is insufficient, which easily leads to poor contact.

The flow channel 24 and the inner wall surface of the accommodating cavity 27 of the sealing body 20 of the present application are completely wrapped, and when the sealing member 60 is formed, the material of the sealing member 60 flows and fills along the inner wall surface of the flow channel 24 and the accommodating cavity 27, At the same time, the top of the closed end 21 is fully covered to form an integrated sealing structure to achieve better sealing performance. At the same time, in the case of the abutting end 23, the atomization chamber in the abutting end 23 is completely wrapped. 80, to further realize the sealing between the atomized liquid in the flow channel 24 and the air channel 25, and solve the problem that the sealing member 60 is partially combined with the inner wall surface of the bracket body 201 in the prior art, and there is still a joint surface area In order to avoid the problem of cracking in the bonding area, resulting in the problem of airtightness, if the sealing member 60 is not tightly combined with the bracket body 201, a good airtightness can still be maintained by adopting this solution.
