The conductive structure of the atomizer 10 includes liquid-guiding cotton 400 and a ventilation sheet 600. The liquid-guiding cotton 400 can be an integral cotton formed by compacting single-layer thick cotton or multiple layers of thin cotton, and has a good self-ventilation function.

Referring to fig. 4 in combination, fig. 4 is a schematic view of a portion of a nebulizer according to some embodiments of the utility model.

In some embodiments, the ventilation sheet 600 has a second surface 620 disposed opposite to the first surface 610, where the first surface 610 is an upper surface of the ventilation sheet 600 abutting against the liquid-guiding cotton 400, and the second surface 620 is a lower surface of the ventilation sheet 600 facing away from the liquid-guiding cotton 400. One end of the micro-holes 601 penetrates through to the first surface 610 of the ventilation sheet 600 and the other end penetrates through to the second surface 620 of the ventilation sheet 600, so that the atomized substrate on the first surface 610 can be guided to the second surface 620 through the micro-holes 601.

The nebulizer 10 further comprises a nebulizer 630 for converting a nebulized substrate into an aerosol, the nebulizer 630 being disposed on the second surface 620 of the ventilation sheet 600. Wherein, the atomizing member 630 comprises a heating element 6301 and a conductive electrode 6302, the heating element 6301 is at least partially arranged in the region of the ventilation sheet 600 provided with the micropores 601, and the heating element 6301 is electrically connected with the conductive electrode 6302.

The heating element 6301 may be disposed at a middle region of the second surface 620, and the conductive electrode 6302 may be disposed at edge regions of both ends of the second surface 620.

Referring to fig. 1 and 5 in combination, fig. 5 is a schematic view of a partial cross-sectional structure of the atomizer in the embodiment of fig. 2.

In some embodiments, the bracket 300 has a receiving groove 302, where the receiving groove 302 is a groove with a downward notch for receiving the liquid-guiding cotton 400. The conducting opening 301 of the bracket 300 may be opened at the bottom wall 310 of the accommodating groove 302, and the liquid-guiding cotton 400 is accommodated in the accommodating groove 302.

With continued reference to fig. 5, and with reference to fig. 6 and fig. 7 in combination, fig. 6 is a schematic structural diagram of liquid-guiding cotton provided in some embodiments of the present utility model, and fig. 7 is a schematic structural diagram of an atomization cap provided in some embodiments of the present utility model.

The accommodating groove 302 can also accommodate an atomization cap 500, and the atomization cap 500 can be used for limiting the liquid guide cotton 400. The atomization cap 500 includes a surrounding wall 510 surrounding the housing space 501, and a supporting wall 520 extending from the bottom end of the surrounding wall 510, and the liquid-guiding cotton 400 can be disposed in the housing space 501.

Wherein, the side portion 410 of the liquid guiding cotton 400 is abutted against the surrounding wall 510 of the atomization cap 500, and the atomization cap 500 can limit the liquid guiding cotton 400 by abutting the side portion 410 of the liquid guiding cotton 400 by the surrounding wall 510. In particular, the liquid-permeable cotton 400 may be in an interference fit with the surrounding wall 510.

When the atomizer 10 is assembled, the liquid-guiding cotton 400 may be first put into the atomization cap 500, the liquid-guiding cotton 400 may be fixed by the cooperation of the side 410 and the surrounding wall 510, and then the atomization cap 500 may be put into the receiving groove 302. The atomization cap 500 may be made of a metal material, and has high rigidity and is not easily deformed. After the liquid-guiding cotton 400 is loaded into the atomization cap 500, the atomization cap 500 may be loaded into the receiving groove 302, and a surrounding wall 510 of the atomization cap 500 may be disposed between the sidewall 320 of the receiving groove 302 and the side 410 of the liquid-guiding cotton 400 and in an interference fit with the sidewall 320 of the receiving groove 302.

In addition, the top 420 of the liquid-guiding cotton 400 may abut against the bottom wall 310 of the accommodating groove 302 and cover the through opening 301 on the bottom wall 310, so that the atomized substrate guided out of the through opening 301 may be entirely guided into the liquid-guiding cotton 400. The liquid-guiding cotton 400 can be made of plant fibers, and can lock and store the atomized matrix therein to a certain extent, and this characteristic enables the liquid-guiding cotton 400 to stably and smoothly guide the atomized matrix onto the ventilation sheet 600, thereby realizing stable supply of the atomized matrix.

The edge of the bottom 430 of the liquid-guiding cotton 400 may abut against the abutment wall 520 of the atomization cap 500, so that the abutment wall 520 may cooperate with the bottom wall 310 of the receiving groove 302 to press the liquid-guiding cotton 400. It should be noted that the material characteristics of the liquid-guiding cotton 400 determine that the liquid-guiding cotton is easy to loosen in the absence of pressing, especially when other parts of the liquid-guiding cotton 400 are pressed, and the bottom 430 is not pressed, the liquid-guiding cotton 400 is easy to loose in the circumference, so that the atomized substrate leaks out. In the embodiment of the utility model, the abutting wall 520 is arranged at the bottom edge of the surrounding wall 510 of the atomization cap 500, and the abutting wall 520 abuts against the edge of the bottom 430 of the liquid-guiding cotton 400, so that the possibility of leakage of the atomized substrate from the liquid-guiding cotton 400 can be reduced.

Optionally, the liquid guiding cotton 400 is in interference fit with the bottom wall 310 of the accommodating groove 302 and the abutting wall 520 of the atomization cap 500, so as to ensure that the liquid guiding cotton 400 has a sufficient compression amount. Wherein, the thickness of the liquid-guiding cotton 400, i.e. the height of the side portion 410 of the liquid-guiding cotton 400, may be greater than the height of the surrounding wall 510, so that the liquid-guiding cotton 400 protrudes from the surrounding wall 510 after being loaded into the atomizing cover 500. In this way, after the atomization cap 500 is installed in the receiving groove 302, the top 420 of the liquid guide cotton 400 may contact the bottom wall 310 of the receiving groove 302, and as the atomization cap 500 moves further, the amount of compression applied to the liquid guide cotton 400 increases further.

The atomization cap 500 and the bracket 300 may be combined by side riveting to improve the compression therebetween. Assembly of the atomization cap 500 with the bracket 300 can be considered complete when the surrounding wall 510 is fully seated within the receiving recess 302 and the bottom end surface of the abutment wall 520 is flush with the bottom end surface of the side wall 320 of the receiving recess 302. That is, the bottom end surface of the atomizing cover 500 may be flattened with the bracket 300 to limit. Of course, in some embodiments, the depth of the atomizing cover 500 within the receiving channel 302 may be further increased, i.e., the bottom end surface of the abutment wall 520 may be slightly higher than the bottom end surface of the side wall 320.

The enclosure wall 510 of the atomization cap 500 can be sized smaller than the side wall 320 of the receiving recess 302 such that after the atomization cap 500 is installed in the receiving recess 302, the enclosure wall 510 is received in the receiving recess 302, and an end of the enclosure wall 510 remote from the abutment wall 520 can be spaced from the bottom wall 310 of the receiving recess 302, i.e., a gap exists between the top end of the enclosure wall 510 and the bottom wall 310. By this design, it is ensured that when the atomizing cover 500 is fitted into the accommodating groove 302, the liquid-guiding cotton 400 can collide with the bottom wall 310 of the accommodating groove 302 and has a sufficient amount of compression, i.e., the surrounding wall 510 does not collide with the bottom wall 310 between the liquid-guiding cotton 400 attaining a sufficient amount of compression.

Wherein the liquid-conducting cotton 400 has a thickness of not more than 10 mm and not less than 0.3 mm, such as 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, etc.

In some embodiments, the wall 520 of the atomization cap 500 is provided with an opening 502 in communication with the receiving space 501, and the ventilation flap 600 may be disposed within the opening 502. The abutment wall 520 may surround the ventilation sheet 600 to achieve a limit of the ventilation sheet 600. The shape of the opening 502 on the supporting wall 520 may be adapted to the ventilation sheet 600, and the side portion of the ventilation sheet 600 disposed in the opening 502 abuts against the supporting wall 520.

The air exchange tabs 600 may be inserted into the openings 502 after the atomization cap 500 is installed into the receiving chamber 302. The first surface 610 and the second surface 620 of the ventilation sheet 600 may respectively abut against the liquid-guiding cotton 400 and the power supply electrode 900. The power supply electrode 900 of the atomizer 10 is disposed on a side of the ventilation sheet 600 away from the liquid-guiding cotton 400, and the power supply electrode 900 abuts against the conductive electrode 6302 on the second surface 620 of the ventilation sheet 600 and is electrically connected to the conductive electrode 6302.

Therefore, the supporting wall 520 of the atomization cap 500 can limit the air exchanging fin 600 in the horizontal direction, and the liquid guide cotton 400 and the power supply electrode 900 can limit the air exchanging fin 600 in the vertical direction in a matched mode, so that the assembly structure is simplified, and the installation efficiency is improved. Of course, in some embodiments, the air exchange sheet 600 may also be limited by other structures, for example, the supporting wall 520 is provided with a protrusion for limiting the air exchange sheet 600, and the limiting structure of the air exchange sheet 600 is not limited to the above embodiments.

With continued reference to fig. 2, and with reference to fig. 8, fig. 8 is a schematic cross-sectional view of the atomizer of the embodiment of fig. 2 at another viewing angle.

In some embodiments, the boot seal 200 of the atomizer 10 may be sleeved on the bracket 300 and an interference fit is provided between the housing 100 and the bracket 300 to prevent leakage of the atomized matrix within the reservoir 102. The housing 100 and the bracket 300 may be made of plastic, and the sealing sleeve 200 may be made of silica gel.

The base 700 of the atomizer 10 may be fitted into the installation space 101 from an opening in the bottom of the housing 100 and engaged with the bottom of the housing 100. Specifically, the opposite sides of the base 700 and the housing 100 may be provided with mating tenons and mortises, respectively, to cooperatively achieve a snap-fit connection. The seal ring 800 of the atomizer 10 may be sleeved on the base 700 and disposed between the base 700 and the housing 100 in an interference manner, so as to prevent condensate from flowing back to the bottom side of the base 700. Wherein, the base 700 may be made of plastic, and the sealing ring 800 may be made of silica gel.

The power supply electrode 900 of the atomizer 10 may be disposed through the base 700 and abuts against the second surface 620 of the ventilation sheet 600. The base 700 and the power supply electrode 900 may be assembled with the liquid-guiding cotton 400, the atomization cap 500, and the ventilation sheet 600, and then be assembled into the housing 100 to complete the assembly of the atomizer 10. The power supply electrode 900 may be made of a metal material.

The base 700 is provided with an air inlet 701 communicated with the installation space 101, the top end of the housing 100 is provided with an air outlet 103 communicated with the installation space 101, and a gap exists between a part of the bracket 300 and the housing 100, so that air flow entering the installation space 101 from the air inlet 701 can flow to the air outlet 103 through the gap, and therefore atomized matrix can be transferred to the air outlet 103 along with the air flow after being converted into aerosol on the second surface 620 of the air exchange plate 600.

The utility model further provides an electronic atomization device. Referring to fig. 9, fig. 9 is a schematic structural diagram of an electronic atomization device according to some embodiments of the utility model.

Specifically, the internal control power source of the controller 20 may be electrically connected to the power supply electrode 900 of the atomizer 10 and further control the switching of the atomizer 630.
