In some embodiments, the outlet tube 12 may include a first tube segment 121 connected to the inside of the top wall of the housing 11 and a second tube segment 122 extending downward from the lower end of the first tube segment 121. The second tube segment 122 is inserted into the atomizing assembly 20. The outer surface of the second tube segment 122 may form a guide structure that facilitates insertion into the atomizing assembly 20. Specifically, in some embodiments, the outer surface of the second pipe section 122 is in a conical shape with the outer diameter decreasing from top to bottom, and the conical outer surface forms a guiding structure of the second pipe section 122. First pipe section 121 can be the pipe form, and the surface of first pipe section 121 can outwards extend and be formed with at least one protruding muscle 123, and the lower terminal surface of this at least one protruding muscle 123 supports and leans on in atomization component 20's up end, and this structure multiplicable outlet duct 12 and atomization component 20 support contact area, still can guarantee that stock solution chamber 110 has more stock solution space simultaneously.

As shown in fig. 2 and 5, the heat generating component 22 may include a liquid absorbent 221 and a heat generating body 222 disposed on the liquid absorbent 221. Liquid 221 is in fluid communication with reservoir 110 and is adapted to adsorb liquid aerosol matrix from reservoir 110. The liquid absorbent 221 may be a porous ceramic liquid absorbent, although it is understood that the liquid absorbent 221 may not be limited to a porous ceramic liquid absorbent in other embodiments. The liquid absorbing material 221 may be a hollow round tube, and an atomizing hole 220 communicated with the air outlet channel 120 is formed through the liquid absorbing material along the longitudinal direction. The atomization hole 220, the liquid suction body 221 and the air outlet pipe 12 can be coaxially arranged.

The heating element 222 may be a metal heating sheet, and is disposed on the wall of the atomizing hole 220, and is used for heating the atomizing substrate on the liquid absorbing material 221 after being powered on to atomize the atomizing substrate to form the atomizing gas. It is understood that the heat generating body 222 may not be limited to a heat generating sheet, for example, in other embodiments, it may also be a heat generating wire or a heat generating film.

Further, the heating element 22 may further include two conductors 223 disposed on the liquid absorbent 221 and electrically connected to both poles of the heating element 222. The two conductive bodies 223 may be disposed on a lower end surface of the liquid absorbing body 221, and the two conductive bodies 223 are respectively located on two circumferential sides of the atomization hole 220. The lower end surface of the liquid absorbing body 221 may further be formed with a slot 2211 extending radially therethrough, and the two electric conductors 223 may be respectively located at two opposite sides of the slot 2211. The slot 2211 separates the two electrical conductors 223 from each other to provide insulation and to facilitate airflow into the atomization orifice 220. In some embodiments, the conductive body 223 may include a connecting portion 2231 disposed on the lower end surface of the liquid absorbing body 221 and an extending portion 2232 extending from a side of the connecting portion 2231 near the slot 2211 toward the inside of the atomizing hole 220. The connecting portion 2231 is used for connecting and conducting with the electrode column 24, and may have a substantially semicircular ring shape. The inner diameter and the outer diameter of the connecting portion 2231 may be respectively identical to those of the liquid absorbing body 221, so as to ensure that the connecting portion 2231 has a sufficient contact area. The extension 2232 extends into the atomization hole 220 and is connected to and conducted with the heating element 222.

As shown in fig. 2, 5, 6 and 7, in some embodiments, the heat generating base 23 may be made of a soft material such as silicon gel. Wherein, the soft material can be a material with hardness less than or equal to 85 degrees Shore A. In other embodiments, the heat generating base 23 can be made of other materials similar to silicone rubber, such as TPE, TPU, etc. The heat-generating base 23 is formed with a heat-generating chamber 230, and at least most of the heat-generating component 22 is accommodated in the heat-generating chamber 230. The heat generation chamber 230 may have first and second sealing portions 2301 and 2302 formed at its longitudinal ends, respectively, and the first and second sealing portions 2301 and 2302 are sealingly engaged with the outer peripheral surfaces of the respective longitudinal ends of the liquid absorbent body 221. Specifically, in the present embodiment, the top and the bottom of the cavity wall of the heat generating cavity 230 may protrude inward in the radial direction to form a first sealing portion 2301 and a second sealing portion 2302 respectively for sealing the top and the bottom of the suction liquid 221. The first sealing portion 2301 and the second sealing portion 2302 may be annular and respectively have interference fit with the top outer peripheral surface and the bottom outer peripheral surface of the liquid absorbing body 221, and the sealing performance of the heat generating seat 23 is improved by the interference fit. At least one liquid inlet hole 2320 for communicating the reservoir chamber 110 with the heat generating chamber 230 is further formed on the heat generating base 23, so as to communicate the liquid absorption 221 with the reservoir chamber 110.

In some embodiments, the heat generating seat 23 may include a first sleeve 231 at a lower portion and a second sleeve 232 at an upper portion. The cross-sectional shape of the first sleeve body 231 is matched with the cross-sectional shape of the inner side of the bottom of the outer shell 11, and in the embodiment, the cross-sectional shape of the first sleeve body 231 is approximately oval. The first sleeve 231 is sleeved on the base 21 and can be in sealing fit with the outer surface of the base 21, and a receiving cavity 2310 for receiving the base 21 is formed on the bottom surface of the first sleeve 231 in a concave manner. A sealing groove 2313 for fitting the supporting portion 213 of the base 21 may be formed in an upper concave portion of the bottom surface of the receiving cavity 2310, i.e., the lower end surface of the first sleeve 231. The sealing groove 2313 may be substantially circular and surround the bottom of the liquid absorber 221, so as to enhance the sealing property of the second sealing portion 2302.

The first sleeve 231 is sealingly fitted between the outer peripheral surface of the base 21 and the inner peripheral surface of the housing 11, and seals the lower end opening end of the housing 11 and the reservoir 110. The outer circumferential surface of the first sleeve 231 may be outwardly protruded to form at least one third sealing portion 2311, and the at least one third sealing portion 2311 is in interference fit with the inner circumferential surface of the housing 11 to enhance the sealing performance of the heat generating seat 23. In the present embodiment, there are two third sealing portions 2311, and the two third sealing portions 2311 are spaced apart from each other.

The first sleeve 231 is formed with a ventilation hole 2312 along the longitudinal direction for communicating the reservoir 110 and the receiving cavity 2310. When the air pressure in the liquid storage cavity 110 is too low, the outside air can enter the liquid storage cavity 110 through the ventilation hole 2312, so that the air pressure in the liquid storage cavity 110 is increased, and the situation that the liquid discharging is not smooth due to too low air pressure in the liquid storage cavity 110 is avoided. The ventilation holes 2312 can be straight-through holes and can be arranged on one side of the long axis of the first sleeve body 231, and the asymmetric arrangement of the ventilation holes 2312 on the first sleeve body 231 can break the stress balance of the air bubbles at the ventilation holes 2312, prevent the air bubbles from being retained and blocking the ventilation holes 2312 and improve the ventilation performance of the ventilation holes 2312. Furthermore, the upper end surface of the air vent 2312 (the end surface communicated with the liquid storage cavity 110) can be arranged to protrude out of the upper end surface of the first sleeve body 231, that is, the upper end surface of the air vent 2312 is higher than the upper end surface of the first sleeve body 231 around the air vent 2312, so that air bubbles can be separated from the air vent 2312 more easily, and the air bubbles are prevented from being retained and blocking the air vent 2312. It is understood that in other embodiments, the ventilating holes 2312 can be arranged on both sides of the first sleeve body 231, and the ventilating holes 2312 can be symmetrically arranged or asymmetrically arranged, for example, the cross-sectional areas of the ventilating holes 2312 are different, or the heights of the upper end surfaces of the ventilating holes 2312 are different.

The second sleeve 232 may be formed by extending the upper end surface of the first sleeve 231 upward. The second sleeve 232 may have a circular tube shape, and an outer diameter of the second sleeve 232 may be smaller than or equal to an outer diameter of a short axis of the first sleeve 231. The top surface of the second sleeve body 232 is recessed to form an air outlet 2321 for inserting the air outlet pipe 12, and the air outlet 2321, the heating cavity 230 and the accommodating cavity 2310 are sequentially communicated from top to bottom. The second pipe section 122 of the outlet pipe 12 is inserted into the outlet hole 2321, the outer circumferential surface of the second pipe section 122 is in sealing fit with the hole wall of the outlet hole 2321, and the lower end surface of the convex rib 123 abuts against the upper end surface of the second sleeve 232. The wall of outlet 2321 may be extended inward to form at least one fourth sealing portion 2322 to seal the lower end of outlet pipe 12. In this embodiment, there are two fourth sealing portions 2322, and the two fourth sealing portions 2322 are spaced up and down and are respectively in interference fit with the outer circumferential surface of the second pipe segment 122. The bottom of the air outlet 2321 may further extend inward to form an annular abutting portion 2323, the lower end surface of the second tube segment 122 may abut against the upper end surface of the abutting portion 2323, and the upper end surface of the liquid absorbing body 221 may abut against the lower end surface of the abutting portion 2323.

The liquid inlet 2320 may be opened on the sidewall of the second sleeve 232 and may be disposed corresponding to the high temperature region of the absorbent 221. The high-temperature region of the liquid absorbent 221 corresponds to the position of the heating element 222 or the position of the dense region of the heating element 222. The liquid absorption body 221 in the high-temperature area is closer to the heating body 222, so that the temperature rise is faster after the heating body 222 generates heat, and the liquid inlet hole 2320 is arranged corresponding to the high-temperature area of the liquid absorption body 221, so that the liquid atomization matrix is rapidly guided into the high-temperature area of the liquid absorption body 221, and the dry burning can be avoided. In this embodiment, two liquid inlet holes 2320 are respectively formed on two opposite sides of the second sleeve body 232, and the lower side of the liquid inlet hole 2320 may extend downward to the upper end surface of the first sleeve body 231. It is understood that in other embodiments, the number of the liquid inlet 2320 may be one or more than two.

The wall of the heat generating chamber 230 may further be provided with at least one liquid guiding structure 233 communicated with the liquid inlet aperture 2320 for guiding the liquid atomized matrix flowing from the liquid inlet aperture 2320 to the portion of the liquid 221 not corresponding to the liquid inlet aperture 2320. The at least one liquid guiding structure 233 may be disposed corresponding to a high temperature region of the liquid-absorbing body 221, and rapidly guides the liquid atomized medium to the high temperature region of the liquid-absorbing body 221, thereby preventing dry burning from occurring. In this embodiment, there are two liquid guiding structures 233, and the two liquid guiding structures 233 and the two liquid inlet holes 2320 are disposed at an included angle of approximately 90 degrees. Each liquid guiding structure 233 may include at least one first liquid guiding channel 2331 extending along the circumferential direction of the heat generating chamber 230. In the present embodiment, each liquid guiding structure 233 includes a plurality of first liquid guiding slots 2331 arranged in parallel, and two circumferential sides of each first liquid guiding slot 2331 are respectively communicated with the two liquid inlet holes 2320. Further, each liquid guiding structure 233 may further include at least one second liquid guiding channel 2332 communicating with the plurality of first liquid guiding channels 2331, and the second liquid guiding channels 2332 may extend in a longitudinal direction. The first liquid guide tank 2331 and the second liquid guide tank 2332 are each formed of a thin groove which automatically generates surface tension to realize automatic liquid guide and provide excellent liquid guide capability. Further, the first liquid guide tank 2331 and the second liquid guide tank 2332 may be formed of a capillary tank capable of generating a capillary force, and the liquid guide effect is further improved by the capillary force. In some embodiments, the distance L between first liquid guide channel 2331, second liquid guide channel 2332, and liquid body 221 can be less than or equal to 1mm, preferably less than or equal to 0.6mm, respectively, for better liquid guide.

As shown in fig. 2, 5, 6 and 8, the base 21 is embedded in the bottom of the housing 11, and may be made of a hard material such as plastic. The base 21 may include a seat body 211 and a fitting portion 212 extending upward from the seat body 211. The cross-sectional shape of the seat 211 is adapted to the cross-sectional shape of the inner side of the bottom of the housing 11, and in this embodiment, the cross-sectional shape of the seat 211 is substantially elliptical. The holder body 211 can be inserted into the housing 11 from the bottom opening end of the housing 11, closing off the bottom opening of the housing 11. The seat 211 may be snap-fit to the housing 11. In some embodiments, two opposite sidewalls of the retaining body 211 may respectively have a snap 2111 protruding outwards, and the retaining body 211 may be snap-connected to the housing 11 through the snap 2111. The outer peripheral surface of the seat body 211 can be recessed to form a plurality of grooves 2112, and the grooves 2112 are uniformly distributed along the outer peripheral surface of the seat body 211 at intervals, so that the base 21 can be prevented from shrinking during injection molding. At least one air inlet hole 210 communicated with the outside is formed on the base 21 along the longitudinal direction. In the embodiment, there are two air inlets 210, and the two air inlets 210 can be distributed on the short axis of the base 211. The two air inlets 210 can be staggered with the atomizing hole 220 in the vertical direction, so that condensate in the atomizing hole 220 is prevented from directly falling into the air inlets 210 to cause liquid leakage.

The fitting portion 212 is sealably sleeved in the receiving cavity 2310 of the heat generating base 23, and an outer cross-sectional dimension of the fitting portion 212 is smaller than an outer cross-sectional dimension of the base 211. The upper end surface of the fitting portion 212 forms a supporting end surface 2121 for supporting the heat-generating base 23, and at least one liquid-storing and air-exchanging structure 214 is disposed on the supporting end surface 2121. The liquid storage and air exchange structure 214 may include at least one air exchange tank 2141 in communication with the air exchange holes 2312 and the air inlet holes 210, respectively, and at least one liquid storage tank 2142 in communication with the at least one air exchange tank 2141. Because the lower end surface of the heating base 23 is tightly attached to the supporting end surface 2121, the size of the ventilation channel formed by the lower end surface of the heating base 23 and the ventilation groove 2141 is stable, the ventilation effect is good, and the ventilation channel is controllable. Stock solution structure 214 of taking a breath can have two, and two stock solution structures 214 of taking a breath can be rotational symmetry for the axis of base 21 and arrange to need not to distinguish left right direction when seat 23 that generates heat assembles on base 21, promote the packaging efficiency, can realize automated production more conveniently.

The air vent groove 2141 has a first end and a second end disposed opposite to each other. The first end of the ventilation tank 2141 is communicated with the ventilation hole 2312 and further communicated with the liquid storage cavity 110, so that the ventilation tank 2141 has a liquid storage function, can store certain condensate, and guides the condensate generated during ventilation into the liquid storage tank 2142. The air vent 2141 may be bent, for example, in a substantially zigzag shape, S-shape, or serpentine shape, to extend the air vent path of the air vent 2141, increase the amount of liquid stored in the air vent 2141, and avoid leakage due to too short air vent path. The second end of the breather tank 2141 is in communication with the intake vent 210 and is in fluid-conducting communication with the liquid absorbent 221, thereby allowing condensate to flow back to the liquid absorbent 221 for re-atomization. The ventilation tank 2141 may be formed of a fine groove, and the ventilation tank 2141 may be formed of a capillary groove capable of generating capillary force, and the liquid is automatically guided by the capillary force, so that the condensate in the ventilation tank 2141 flows back to the liquid absorbent 221. In some embodiments, the distance between the end of the second end of the air vent 2141 and the liquid absorbing body 221 may be less than or equal to 1mm, and preferably less than or equal to 0.6mm, for better drainage. The liquid storage tank 2142 may be disposed near the second end of the air exchange tank 2141 and communicate with the second end of the air exchange tank 2141, so that the condensed liquid in the liquid storage tank 2142 can flow back to the liquid absorption liquid 221 quickly for re-atomization.

In some embodiments, the base 21 may further include a supporting portion 213 extending upward from the supporting end surface 2121 of the fitting portion 212, and the supporting portion 213 is sealingly embedded in the sealing groove 2313 for supporting the heat-generating seat 23 and improving the sealing performance of the heat-generating seat 23. Specifically, the cross section of the support portion 213 may be substantially annular, and the outer diameter of the support portion 213 is equal to or smaller than the minor axis diameter of the support end face 2121. The support portion 213 surrounds the two inlet holes 210 and the two electrode holes 2113, and at least one liquid storage tank 2130 for storing condensate is formed therein. The supporting portion 213 surrounds the second sealing portion 2302 and is disposed near the second sealing portion 2302, and can press the second sealing portion 2302 inwards to tightly contact the liquid 221, thereby ensuring good sealing performance for the liquid 221. The vertical cross-sectional shape of the sealing groove 2313 is matched with the vertical cross-sectional shape of the support portion 213. In some embodiments, the outer diameter of the supporting portion 213 may decrease from bottom to top and the inner diameter may increase from bottom to top to facilitate the insertion into the sealing groove 2313, for example, the longitudinal section of the supporting portion 213 may be trapezoidal, inverted V-shaped, arc-shaped, etc.
