Among them, the atomizer usually includes a hollow housing and an atomization core disposed inside the housing. An atomization channel and a liquid storage cavity for supplying atomization liquid to the atomization core are also provided inside the housing. The atomization core is used to heat and atomize the atomization liquid supplied by the liquid storage cavity to form an inhalable aerosol leading to the atomization channel.

[0003] In related technologies, the atomization core includes an oil guiding body and a heating element disposed on the oil guiding body.

[0041] Refer to Figures 1 to 9 , the atomizer according to the embodiment of the present application includes a housing 100, an oil guiding body 200, a heating element 300, a base 400, an electrode post 500 and an elastic structure.

[0042] Specifically, the housing 100 is a hollow structure with an opening. A liquid storage cavity 110 is arranged inside the housing 100. The oil guiding body 200 is a rigid porous structure. The oil guiding body 200 is arranged inside the housing 100. The oil guiding body 200 has a liquid absorption surface a and an atomization surface b which are oppositely arranged. The liquid absorption surface a of the oil guiding body 200 is in fluid communication with the liquid storage cavity 110. The heating element 300 is arranged on the atomization surface b of the oil guiding body 200. The heating element 300 has a conductive elastic sheet 310 for connecting to a power source. There is a gap between the conductive elastic sheet 310 and the atomization surface b of the oil guiding body 200. The heating element 300 is used to heat and atomize the atomization liquid supplied by the oil guiding body 200 to form an inhalable aerosol. The base 400 is arranged at the opening of the housing 100. A through hole 410 facing the conductive elastic sheet 310 is arranged on the base 400. The electrode post 500 is movably inserted into the through hole 410. One end of the electrode post 500 close to the heating element 300 abuts against the conductive elastic sheet 310. An elastic structure is arranged on the base 400 and acts on the electrode post 500. The elastic structure is used to provide an elastic force for driving the electrode post 500 to move towards the conductive elastic sheet 310.

[0043] When the actual axial assembly space of the electrode post 500 is relatively large, the elastic structure can provide an elastic force for driving the electrode post 500 to move towards the conductive elastic sheet 310, so as to be able to absorb (i.e., adapt to) the dimensional tolerances of relevant components, which is beneficial to ensuring good contact between the electrode post 500 and the conductive elastic sheet 310; when the actual axial assembly space of the electrode post 500 is relatively small, since there is a gap between the conductive elastic sheet 310 and the atomization surface b of the oil guiding body 200, the conductive elastic sheet 310 has a certain deformation space, so as to be able to absorb (i.e., adapt to) the dimensional tolerances of relevant components, which is beneficial to preventing the oil guiding body 200 from being cracked by the electrode post 500. Among them, after the conductive elastic sheet 310 is deformed by the extrusion of the electrode post 500, it can provide an elastic force acting on the electrode post 500, which is beneficial to ensuring good contact between the electrode post 500 and the conductive elastic sheet 310.

[0044] It should be noted that in some of the embodiments, the heating element 300 is a heating wire. Of course, the heating element 300 can also be a heating film or other heating structures, which are not limited herein.

[0045] Refer to Figure 1 、 Figure 3 and Figure 4, in some of these embodiments, the elastic structure is an elastic sheet 600. The elastic sheet 600 includes a base portion 610 and two wing portions 620 respectively disposed on opposite sides of the base portion 610. The wing portions 620 are connected to the base 400. At least one of the wing portions 620 and the base portion 610 has elastic potential energy. The electrode post 500 passes through the base portion 610, and a contact portion 510 is provided in the region between the two ends of the electrode post 500. The contact portion 510 elastically abuts against the side of the base portion 610 facing the oil guiding body 200, so that the elastic force provided by the elastic potential energy of the elastic sheet 600 acts on the electrode post 500.

[0046] Refer to Figure 1 , Figure 3 and Figure 4 , in some of these embodiments, both of the two wing portions 620 extend outward and obliquely upward. The base portion 610 has an avoidance through hole 611. The electrode post 500 passes through the avoidance through hole 611. Both of the two wing portions 620 have mounting through holes 621. Two spaced-apart mounting posts 420 are provided on the base 400 corresponding to the two wing portions 620. The two mounting posts 420 respectively pass through the two mounting through holes 621. Its structure is simple and easy to implement. Among them, the two wing portions 620 can extend in a straight line or in an arc, which is not limited herein.

[0047] Specifically, the distance between the two mounting posts 420 is greater than the distance between the two avoidance through holes 611 to stretch the two wing portions 620 outward, so that the elastic sheet 600 has elastic potential energy and has a tendency to deform upward, thereby providing an elastic force acting on the contact portion 510. Of course, the elastic sheet 600 may also have elastic potential energy due to the base portion 610 being squeezed, which is not limited herein.

[0048] Refer to Figure 5 and Figure 6 , in some of these embodiments, the elastic structure is an elastic ring 700. The elastic ring 700 includes two U-shaped portions 710 with openings facing inward and two arc-shaped portions 720 connected between the two U-shaped portions 710 with openings facing upward. The two U-shaped portions 710 and the two arc-shaped portions 720 enclose a closed ring structure. The arc-shaped portion 720 has elastic potential energy. The electrode post 500 passes through between the two arc-shaped portions 720. A contact portion 510 is provided in the region between the two ends of the electrode post 500. The contact portion 510 elastically abuts against the side of the arc-shaped portion 720 facing the oil guiding body 200, so that the elastic force provided by the elastic potential energy of the arc-shaped portion 720 acts on the electrode post 500. Two spaced-apart mounting posts 420 are provided on the base 400 corresponding to the two U-shaped portions 710. The two mounting posts 420 respectively pass through the two U-shaped portions 710.

[0049] Specifically, the distance between the two mounting posts 420 is greater than the distance between the two U-shaped parts 710, so that the two U-shaped parts 710 stretch the two arc-shaped parts 720 outwards, enabling the two arc-shaped parts 720 to have elastic potential energy and a tendency to deform upwards, thereby providing an elastic force acting on the abutting part 510. Of course, the arc-shaped part 720 may also have elastic potential energy due to being squeezed, which is not limited herein.

[0050] It should be noted that in some of these embodiments, both the elastic sheet 600 and the elastic ring 700 are made of rubber or silica gel. Of course, the elastic sheet 600 and the elastic ring 700 may also be made of solid metals, such as copper, iron, stainless steel, etc., which is not limited herein.

[0051] Refer to Figure 4 , in some of these embodiments, a guiding structure is provided between the base 400 and the electrode post 500. The guiding structure includes a sliding block 520 and a guiding chute 430 that are mutually adapted. One of the sliding block 520 and the guiding chute 430 is provided on the electrode post 500, and the other is provided on the base 400 and extends along the axial direction of the electrode post 500 (i.e., extending towards the heating element 300). The guiding structure is used to limit the movement trajectory of the electrode post 500, which is beneficial to improving the stability and reliability of the electrode post 500 during operation. Specifically, the sliding block 520 and the guiding chute 430 cooperate with each other for limiting, which can not only limit the radial movement of the electrode post 500 along its own axis, but also limit the rotation of the electrode post 500 around its own axis, so that the electrode post 500 can only move towards or away from the conductive elastic sheet 310 along its own axial direction.

[0052] Refer to Figure 4 , in some of these embodiments, the sliding block 520 is provided on the electrode post 500, the guiding chute 430 is provided on the base 400 and extends along the axial direction of the electrode post 500, and the sliding block 520 is inserted into the guiding chute 430, with a simple structure and easy to implement.

[0053] Refer to Figure 4 , in some of these embodiments, the sliding block 520 is provided on the abutting part 510. Of course, the sliding block 520 may also be provided in other areas of the electrode post 500, which is not limited herein.

[0054] It should be noted that in some other embodiments, the sliding block 520 may also be provided on the base 400 and extend along the axial direction of the electrode post 500. Correspondingly, the guiding chute 430 is provided on the abutting part 510, which is not limited herein.

[0055] Refer to Figure 8, in some embodiments thereof, a limiting groove 311 is provided on one side of the conductive elastic sheet 310 facing the electrode post 500, and one end of the electrode post 500 close to the heating element 300 is located in the limiting groove 311, which is beneficial to preventing the end of the electrode post 500 close to the heating element 300 from being displaced relative to the conductive elastic sheet 310, thereby being beneficial to improving the stability and reliability of the electrode post 500 during operation.

[0056] Referring to Figure 1 , Figure 5 and Figure 7 , in some embodiments thereof, an oil outlet hole 120 is provided at the bottom of the liquid storage cavity 110, and an installation groove 130 communicating with the oil outlet hole 120 is provided on one side of the oil outlet hole 120 facing away from the liquid storage cavity 110. The oil guiding body 200 is embedded in the installation groove 130. The liquid absorption surface a of the oil guiding body 200 faces the liquid storage cavity 110 and is in contact with the atomized liquid in the liquid storage cavity 110. An elastic sealing member 800 is clamped between the outer peripheral side wall of the oil guiding body 200 and the inner peripheral side wall of the installation groove 130. Its structure is simple and easy to implement. Among them, the elastic sealing member 800 is used to prevent the atomized liquid in the liquid storage cavity 110 from leaking through the fitting gap between the outer peripheral side wall of the oil guiding body 200 and the inner peripheral side wall of the installation groove 130.

The extending portion 810 is clamped between the step surface of the annular step 210 and the inner wall of the installation groove 130. On the one hand, the extending portion 810 is beneficial to improving the sealing performance; on the other hand, when the actual axial assembly space of the electrode post 500 is small, the extending portion 810 can be deformed by force to compensate for the axial assembly space of the electrode post 500, so as to be able to absorb (i.e., adapt to) the dimensional tolerances of related components, which is beneficial to preventing the oil guiding body 200 from being cracked by the electrode post 500. Among them, after the extending portion 810 is deformed by force, it can provide an elastic force acting on the electrode post 500, which is beneficial to ensuring good contact between the electrode post 500 and the conductive elastic sheet 310.

[0058] It should be noted that, in some embodiments thereof, the elastic sealing member 800 is made of rubber or silica gel.
