Currently, atomizers in aerosol-generating devices are capable of heating and atomizing an aerosol-generating substrate, such as, for example, a smoke oil, stored in a liquid reservoir to generate an aerosol for inhalation by a user. Generally, the atomizer may include an atomizing base having a receiving cavity and a heating element received in the receiving cavity, and an aerosol-generating substrate stored in the liquid storage cavity can enter the receiving cavity to be heated and atomized by the heating element to generate aerosol, however, the aerosol in the receiving cavity is accumulated in the receiving cavity due to condensation, and the aerosol-generating substrate accumulated in the receiving cavity cannot be heated and atomized, so that the aerosol-generating substrate is wasted and the utilization rate is not high. To solve this problem, referring to fig. 1 and 2, an atomizer 10 and an aerosol-generating device 100 are provided in an embodiment of the present application.

Referring to fig. 1 and 2 or fig. 8, an atomizer 10 according to an embodiment of the present invention includes an atomization seat 11 and a heating element 13. The atomizing base 11 is provided with a containing cavity 101, the heating element 13 is arranged in the containing cavity 101, the atomizer 10 further comprises a liquid guide piece 111 positioned in the containing cavity 101 and an aggregation area 112 positioned in the containing cavity 101, the liquid guide piece 111 is connected with the heating element 13, the liquid guide piece 111 stretches into the aggregation area 112, the aggregation area 112 is used for aggregating the aerosol generating substrate 200 (shown in fig. 9), and when the aerosol generating substrate 200 enters the containing cavity 101, the liquid guide piece 111 is used for guiding the aerosol generating substrate 200 aggregated in the aggregation area 112 to flow back to the heating element 13.

The aerosol-generating substrate 200 is an element capable of generating an aerosol, and in particular, the aerosol-generating substrate 200 may be made into fine particles by means of heating or ultrasonic vibration and mixed with air to form an aerosol. The aerosol-generating substrate 200 may be in the form of a solid or liquid. In this application, the aerosol-generating substrate 200 may be a liquid tobacco tar, wherein the tobacco tar is a mixed liquid in which substances such as nicotine and nicotine are dissolved, and the solute thereof is a common organic solute and/or inorganic solute such as propylene glycol, plant glycerol and pure water. Aerosols may be visible or invisible and may include vapors (e.g., fine particulate matter in the gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapors. "aerosol" herein encompasses aerosols generated when the aerosol-generating substrate 200 in the heated aerosol-generating device 100 is heated.

The heating element 13 is a device or material that can generate heat energy and transfer the heat energy to the surrounding environment. Referring to fig. 3, in some embodiments, the heating element 13 may include a porous ceramic 131, a heating layer 133, and a conductive member 135. The porous ceramic 131 is accommodated in the accommodating cavity 101, and the heating layer 133 is disposed on one side of the porous ceramic 131 and is electrically connected to the conductive member 135, so that the porous ceramic 131 can heat and atomize the aerosol-generating substrate 200 entering the accommodating cavity 101. It should be noted that in some embodiments, the porous ceramic 131 is generally prepared by mixing a ceramic slurry with a pore-forming agent and then sintering the mixture, and the sintered ceramic has a plurality of micropores (not shown in the figure). The heating layer 133 may be a heating circuit, a heating film, a heating sheet, a heating wire, a heating net, etc., which is not limited herein. The conductive member 135 may be an electrode, wherein the electrode may be in the form of a sheet, a column, a powder porous shape, or the like, without limitation.

In the present application, the liquid guiding member 111 is connected with the porous ceramic 131 and is located in the accommodating cavity 101, and the liquid guiding member 111 extends into the aggregation area 112 to guide the aerosol-generating substrate 200 in the aggregation area 112 to flow back to the porous ceramic 131, so as to avoid the aerosol-generating substrate 200 from forming a pile in the aggregation area 112 and causing waste.

In some embodiments, the liquid guide 111 may include one, and one liquid guide 111 is connected to any position of the heating element 13. In case that the aerosol is accumulated in the receiving chamber 101 due to condensation, the user can control the position where the aerosol-generating substrate 200 in the receiving chamber 101 is accumulated as much as possible in the liquid guide 111, for example, the user can control the angle of inclination when the aerosol-generating device 100 is sucked so that the aerosol-generating substrate 200 is accumulated as much as possible in the accumulation region 112, thereby enabling the liquid guide 111 to guide the aerosol-generating substrate 200 in the accumulation region 112 to flow back to the heating element 13, and the heating element 13 re-heats the reflowed aerosol-generating substrate 200, thereby enabling to reduce waste of the aerosol-generating substrate 200 on the one hand; on the other hand, the reflow efficiency of the aerosol-generating substrate 200 can also be improved compared to a case where the aerosol-generating substrate 200 in the receiving cavity 101 is only partially or completely absent from the position where the liquid guide 111 is located. It will be appreciated that in some embodiments, one liquid guide 111 may be arranged around the heating element 13, whereby the aerosol-generating substrate 200 in the receiving cavity 101 is able to contact the liquid guide 111 to ensure that the aerosol-generating substrate 200 is able to quickly reflow to the heating element 13, thereby improving the reflow efficiency of the aerosol-generating substrate 200, regardless of whether the aerosol-generating device 100 (shown in fig. 1) is tilted in any direction.

In other embodiments, the liquid guide 111 may include a plurality of liquid guides 111 uniformly spaced around the heating element 13, for example, in the case where the cross-sectional shape of the heating element 13 is quadrangular, the liquid guide 111 may include four liquid guides 111 uniformly connected to four sidewalls 1163 of the heating element 13. The plurality of liquid guides 111 may be disposed such that the aerosol-generating substrate 200 in the receiving cavity 101 may be in contact with at least a portion of the liquid guides 111 regardless of whether the aerosol-generating device 100 (shown in fig. 1) is tilted in any direction, so as to ensure that the aerosol-generating substrate 200 may be quickly reflowed to the heating element 13, thereby improving the reflow efficiency of the aerosol-generating substrate 200.

In the atomizer 10 of the embodiment of the present application, the atomizer 10 includes the liquid guiding member 111 located in the accommodating cavity 101 and the aggregation area 112 located in the accommodating cavity 101, the liquid guiding member 111 is connected with the heating element 13, the liquid guiding member 111 stretches into the aggregation area 112, and the liquid guiding member 111 can guide the aerosol generating substrate 200 aggregated in the aggregation area 112 to flow back to the heating element 13, the heating element 13 can heat the aerosol generating substrate 200 which is atomized and flows back, so that the aerosol generating substrate 200 is prevented from forming accumulation in the accommodating cavity 101 to cause waste, and the utilization rate of the aerosol generating substrate 200 is improved.

The atomizer 10 is further described below with reference to the drawings.

Referring to fig. 2 or 7, in some embodiments, the atomizing base 11 includes a top cover 115 and a base 116, and the top cover 115 includes a top wall 1151 and a peripheral wall 1153 extending from a periphery of the top wall 1151 toward the base 116. The base 116 includes a bottom wall 1161 and a side wall 1163 extending from a periphery of the bottom wall 1161 in a direction toward the top cover 115, and the side wall 1163 of the base 116 is connected with the peripheral wall 1153 of the top cover 115.

Specifically, in some embodiments, the peripheral wall 1153 of the cap 115 may have a connector 1155, and the sidewall 1163 of the base 116 may have a mating member 1165, where the connector 1155 mates with the mating member 1165 to connect the base 116 to the cap 115. Wherein, the connecting member 1155 may be a protrusion, the protrusion extends from the peripheral wall 1153 of the top cover 115 toward a direction away from the top cover 115, the mating member 1165 may be a groove, the groove is recessed from an inner side of the sidewall 1163 of the base 116 (a side of the sidewall 1163 facing the accommodating cavity 101) toward a center away from the accommodating cavity 101, and the protrusion can extend into the groove to realize connection between the base 116 and the top cover 115. Of course, it is also possible that the connecting member 1155 is a groove, the groove is recessed from the outer side of the peripheral wall 1153 of the top cover 115 toward the center of the accommodating cavity 101, the mating member 1165 is a protrusion, the protrusion extends from the side wall 1163 of the base 116 toward the center of the accommodating cavity 101, and the protrusion can extend into the groove to connect the base 116 and the top cover 115. It will be appreciated that in other embodiments, the side wall 1163 of the base 116 and the peripheral wall 1153 of the top cover 115 may be connected by an adhesive, a threaded connection, or a welded connection, which is not limited herein. In this application, the cap 115 and the base 116 may be integrally formed, in which case the peripheral wall 1153 of the cap 115 and the side wall 1163 of the base 116 together form the peripheral wall 110 of the atomizing base 11.

Referring to fig. 4, in general, the aerosol-generating substrate 200 can be deposited on the bottom of the accommodating cavity 101 (i.e., the bottom wall 1161 of the base 116), and if the bottom of the accommodating cavity 101 is not provided with the blocking member 113, the aerosol-generating substrate 200 can freely flow in the accommodating cavity 101, and when the aerosol-generating device 100 is tilted, the aerosol-generating substrate 200 will all flow to one side of the base 116, resulting in a small contact area between a portion of the liquid guide 111 and the aerosol-generating substrate 200, and thus affecting the reflow efficiency of the aerosol-generating substrate 200. In some embodiments, the base 116 may include at least one barrier 113, the barrier 113 being positioned within the receiving cavity 101, the at least one barrier 113 being configured to form the collection region 112, the liquid guide 111 extending into the collection region 112. The blocking member 113 is configured such that, when the aerosol-generating device 100 is tilted, the aerosol-generating substrate 200 can be collected in the collection region 112 instead of being stacked on one side of the base 116, so as to ensure a contact area between the aerosol-generating substrate 200 and the liquid guide 111, and improve the backflow efficiency of the aerosol-generating substrate 200. Specifically, in certain embodiments, the stop 113 may extend from the bottom wall 1161 of the base 116 toward the top cover 115. Wherein the blocking member 113 may be disposed at any position on the bottom wall 1161 of the base 116. The cross-sectional shape of the blocking member 113 may be a regular shape such as an L-shape or a linear shape, or may be an irregular shape.

Referring to fig. 2-4, in some embodiments, the accumulation region 112 is capable of blocking the flow of aerosol-generating substrate 200 (shown in fig. 9) from a first direction X, a second direction Y, and a third direction M, each perpendicular to the central axis of the nebulizer 10, the first direction X being parallel and opposite to the second direction Y, each perpendicular to the third direction M.

Specifically, in some embodiments, in the case where the blocking member 113 forms the aggregation area 112, the blocking member 113 can block the flow of the aerosol-generating substrate 200 in the first direction X, the second direction Y, and the third direction M, and thus, the aerosol-generating substrate 200 within the housing chamber 101 can be aggregated within the aggregation area 112 as much as possible, so that not only can the liquid guide 111 guide the aerosol-generating substrate 200 in the aggregation area 112 back to the heating element 13, waste of the aerosol-generating substrate 200 can be reduced, but also the backflow efficiency of the aerosol-generating substrate 200 can be improved. It should be noted that, in the present embodiment, the collecting region 112 may include only one, in which case, the blocking member 113 may include a first sub-portion 1131 and a second sub-portion 1133 extending from two opposite ends of the first sub-portion 1131, wherein the second sub-portion 1133 extends from two opposite ends of the first sub-portion 1131 toward the peripheral wall 110 of the atomizing base 11. In certain embodiments, the direction of extension of the first sub-portion 1131 may be substantially the same as the first direction X and the direction of extension of the second sub-portion 1133 may be substantially the same as the fourth direction N (the fourth direction N being parallel and opposite to the third direction M), whereby the first sub-portion 1131 and the two second sub-portions 1133 together form the aggregation region 112 to achieve a barrier to flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y and the third direction M.

It will be appreciated that in other embodiments, one end of the first sub-portion 1131 may be connected with the peripheral wall 220 of the nebulizing seat 11, i.e. the first end of the first sub-portion 1131 may be connected with the peripheral wall 110 of the nebulizing seat 11, in which case part of the peripheral wall 110 of the nebulizing seat 11 may be configured as the second sub-portion 1133, in other words, the first sub-portion 1131, the second sub-portion 1133 and the peripheral wall 110 of the nebulizing seat 11 together form the aggregation zone 112 for achieving a blocking of the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y and the third direction M.

Further, in certain embodiments, the aggregation zone 112 is capable of blocking the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y, and the fourth direction N, the fourth direction N being perpendicular to the central axis of the nebulizer 10, the fourth direction N being parallel and opposite to the third direction M.

Specifically, in some embodiments, in the case where the blocking member 113 forms the aggregation area 112, the blocking member 113 can block the flow of the aerosol-generating substrate 200 in the first direction X, the second direction Y, and the fourth direction N, and thus, the aerosol-generating substrate 200 within the housing chamber 101 can be aggregated within the aggregation area 112 as much as possible, so that not only can the liquid guide 111 guide the aerosol-generating substrate 200 in the aggregation area 112 back to the heating element 13, waste of the aerosol-generating substrate 200 can be reduced, but also the backflow efficiency of the aerosol-generating substrate 200 can be improved. It should be noted that, in the present embodiment, the collecting region 112 may include only one, and in this case, the blocking member 113 includes a first sub-portion 1131 and a second sub-portion 1133 extending from two opposite ends of the first sub-portion 1131, wherein the second sub-portion 1133 extends from two opposite ends of the first sub-portion 1131 toward the peripheral wall 110 of the atomizing base 11. In certain embodiments, the direction of extension of the first sub-portion 1131 may be substantially the same as the first direction X and the direction of extension of the second sub-portion 1133 may be substantially the same as the third direction M, whereby the first sub-portion 1131 and the two second sub-portions 1133 together form the aggregation zone 112 to achieve a blocking of the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y and the fourth direction N.

It will be appreciated that in other embodiments, one end of the first sub-portion 1131 may be connected to the peripheral wall 110 of the atomizing base 11, i.e. the first end of the first sub-portion 1131 may be connected to the peripheral wall 110 of the atomizing base 11, in which case part of the peripheral wall 110 of the atomizing base 11 may be configured as the second sub-portion 1133, in other words, the first sub-portion 1131, the second sub-portion 1133 and the peripheral wall 110 of the atomizing base 11 together form the aggregation zone 112 to achieve a blocking of the aerosol-generating substrate 200 from the first direction X, the second direction Y and the third direction M.

In summary, if the atomizer 10 includes two aggregation areas 112 located in the housing 101, one aggregation area 112 can block the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y and the third direction M, and the other aggregation area 112 can block the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y and the fourth direction N, the two aggregation areas 112 can block the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y, the third direction M and the fourth direction N, in other words, no matter in which direction the aerosol-generating device 100 is inclined, the aerosol-generating substrate 200 can be aggregated in the aggregation area 112 rather than being stacked on one side of the base 116, so that the contact area between the aerosol-generating substrate 200 and the liquid guide 111 can be ensured, and the reflow efficiency of the aerosol-generating substrate 200 can be improved.

Referring to fig. 1, 2 and 4, in some embodiments, the height of the barrier 113 is 1.0mm-5.0mm. Specifically, in certain embodiments, the height of the barrier 113 may be any one or any value between any two of 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, and 5.0mm. If the height of the blocking member 113 is less than 1.0mm, the height of the blocking member 113 is too low, and in case the aerosol-generating device 100 is tilted, the blocking member 113 cannot block the aerosol-generating substrate 200 (shown in fig. 9) from flowing towards one side of the base 116, resulting in that no or less aerosol-generating substrate 200 can be accumulated in part of the accumulation subchamber, thereby affecting the reflow efficiency of the aerosol-generating substrate 200. If the height of the barrier 113 is greater than 5.0mm, the number of aerosol-generating substrates 200 that can be aggregated in the aggregation sub-chamber is excessive, and in case of a user inhaling, the aerosol-generating substrates 200 are easily inhaled into the user's mouth, affecting the user's inhalation experience. In the embodiment of the present application, the height of the blocking member 113 is 1.0mm to 5.0mm, so that on one hand, in the case that the aerosol-generating device 100 is tilted, the blocking member 113 can block the aerosol-generating substrate 200 from flowing toward one side of the base 116, thereby improving the backflow efficiency of the aerosol-generating substrate 200; on the other hand, it is possible to avoid excessive aggregation of the aerosol-generating substrate 200 in the aggregation subchamber, resulting in an easy aspiration of the aerosol-generating substrate 200 into the user's mouth in case of an aspiration by the user, thereby enhancing the user experience of the aspiration.

Referring to fig. 1, 6 and 7, in other embodiments, the aggregation zone 112 is also capable of blocking the flow of aerosol-generating substrate 200 (shown in fig. 9) from a fourth direction N, which is perpendicular to the central axis of the nebulizer 10, which is parallel and opposite to the third direction M.

Specifically, referring to fig. 8, in some embodiments, the bottom of the accommodating cavity 101 includes a first side 1011 and a second side 1013 opposite to each other, wherein the aggregation area 112 is recessed from the first side 1011 of the bottom of the accommodating cavity 101 to the second side 1013 of the bottom of the accommodating cavity 101, thereby the aggregation area 112 can block the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y, the third direction M and the fourth direction N, in other words, no matter in which direction the aerosol-generating device 100 is tilted, the aerosol-generating substrate 200 can aggregate in the aggregation area 112 rather than accumulating on one side of the base 116, thereby ensuring the contact area between the aerosol-generating substrate 200 and the liquid guide 111 and improving the reflow efficiency of the aerosol-generating substrate 200. In the present embodiment, the cross-sectional shape of the collecting region 112 includes, but is not limited to, a regular shape such as a circle, a square, or a triangle, and may be an irregular shape.

In some embodiments, the opening 1121 of the collection region 112 is the same size as the first side 1011 of the bottom of the receiving cavity 101. Specifically, the collecting region 112 may be formed by recessing the first side 1011 of the bottom of the accommodating chamber 101 toward the second side 1013 of the bottom of the accommodating chamber 101, in which case the collecting region 112 may be tapered, and the opening 1121 of the collecting region 112 gradually decreases in size in a direction from the first side 1011 of the bottom of the accommodating chamber 101 to the second side 1013 of the bottom of the accommodating chamber 101, whereby, if the aerosol-generating device 100 is tilted, the aerosol-generating substrate 200 in the accommodating chamber 101 can be collected to the bottom of the collecting region 112 (a position of the collecting region 112 near the second side of the base 116), so that the collecting region 112 can block the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y, the third direction M, and the fourth direction N, and the liquid guide 111 extends into the collecting region 112 to reflow the collected aerosol-generating substrate 200 to the heating element 13.

In other embodiments, the size of the opening 1121 of the collection region 112 is smaller than the size of the first side 1011 of the bottom of the receiving cavity 101. Specifically, the aggregation area 112 may be formed by recessing a portion of the first side 1011 of the bottom of the accommodating chamber 101 toward the second side 1013 of the bottom of the accommodating chamber 101, in which case, if the aerosol-generating device 100 is tilted, the aerosol-generating substrate 200 in the accommodating chamber 101 can enter the aggregation area 112, whereby the aggregation area 112 can block the flow of the aerosol-generating substrate 200 from the first direction X, the second direction Y, the third direction M and the fourth direction N, and the liquid guide 111 extends into the aggregation area 112 to reflow the aggregated aerosol-generating substrate 200 to the heating element 13.

Referring to fig. 2, 4 and 5, in some embodiments, the liquid guide 111 is provided with at least one capillary groove 1111, the capillary groove 1111 communicates with the collecting region 112, and the side wall of the capillary groove 1111 is used to flow the aerosol-generating substrate 200 (shown in fig. 9) to the heating element 13.

Specifically, referring to fig. 3, in some embodiments, both ends of the capillary groove 1111 may be connected to the collecting region 112 and the heating body 13, respectively. In the case where the heat generating body 13 includes the porous ceramic 131, the capillary groove 1111 is connected to the porous ceramic 131, and since the porous ceramic 131 has a plurality of micropores, the porous ceramic 131 can form a plurality of minute vacuum gaps and generate negative pressure when the porous ceramic 131 is connected to the liquid guide 111, and thus the porous ceramic 131 can generate suction force to the aerosol-generating substrate 200 in the aggregation region 112. With the liquid guide 111 extending into the aggregation area 112, the aerosol-generating substrate 200 in the aggregation area 112 can flow to the heat-generating body 13 along the side walls 1163 of the capillary groove 1111 by capillary action and suction force of the porous ceramic 131. It should be noted that, in some embodiments, the extending direction of the capillary groove 1111 may be the same as the extending direction L of the liquid guide 111. In other embodiments, the extension direction of the capillary groove 1111 may intersect with the extension direction L of the liquid guide 111. In still other embodiments, the capillary groove 1111 may be spirally disposed on the liquid guide 111 along the extending direction L of the liquid guide 111.

In some embodiments, capillary groove 1111 has a depth of 0.3mm to 1.0mm. Specifically, in certain embodiments, the depth of capillary groove 1111 may be any one or any value between any two of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm. If the depth of the capillary groove 1111 is less than 0.3mm, the volume of the capillary groove 1111 is too small, resulting in a decrease in the flow rate of the back flow of the aerosol-generating substrate 200, affecting the back flow efficiency of the aerosol-generating substrate 200. If the depth of the capillary groove 1111 is greater than 1.0mm, the capillary force of the capillary groove 1111 becomes small or even disappears, thereby also affecting the reflow efficiency of the aerosol-generating substrate 200. In the embodiment of the present application, the depth of the capillary groove 1111 is 0.3mm to 1.0mm, thereby being capable of ensuring the flow rate of the aerosol-generating substrate 200 flowing back in the capillary groove 1111 while preventing the capillary force of the capillary groove 1111 from becoming small, thereby ensuring the backflow efficiency of the aerosol-generating substrate 200.

In some embodiments, capillary groove 1111 has a width of 0.3mm to 0.8mm. Specifically, in certain embodiments, the width of capillary groove 1111 may be any one of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, and 0.8mm, or any value between any two values. If the width of the capillary groove 1111 is less than 0.3mm, the volume of the capillary groove 1111 is too small, resulting in a decrease in the flow rate of the back flow of the aerosol-generating substrate 200, affecting the back flow efficiency of the aerosol-generating substrate 200. If the width of the capillary groove 1111 is greater than 0.8mm, the capillary force of the capillary groove 1111 becomes small or even disappears, thereby also affecting the reflow efficiency of the aerosol-generating substrate 200. In the present embodiment, the width of the capillary groove 1111 is 0.3mm to 0.8mm, thereby being capable of preventing the capillary force of the capillary groove 1111 from becoming smaller while ensuring the flow rate of the back flow of the aerosol-generating substrate 200 in the capillary groove 1111, thereby ensuring the back flow efficiency of the aerosol-generating substrate 200.

With continued reference to fig. 2, 4 and 5, in some embodiments, the distance between the side of the liquid guiding member 111 facing the collecting region 112 and the bottom of the collecting region 112 is 0mm-2.0mm. Specifically, in certain embodiments, the distance between the side of the liquid guide 111 facing the gathering region 112 and the bottom of the gathering region 112 may be any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, and 2.0mm, or any value between any two values. If the distance between the side of the liquid guide 111 facing the aggregation area 112 and the bottom of the aggregation area 112 is greater than 2.0mm, the distance between the side of the liquid guide 111 facing the aggregation area 112 and the bottom of the aggregation area 112 is too far, and in the case where the amount of the aerosol-generating substrate 200 (shown in fig. 9) in the housing chamber 101 is small, the aerosol-generating substrate 200 cannot be in contact with the liquid guide 111, resulting in that the aerosol-generating substrate 200 cannot flow back to the heating element 13, and thus the waste of the aerosol-generating substrate 200 is caused. In the embodiment of the present application, the distance between the side of the liquid guiding member 111 facing the aggregation area 112 and the bottom of the aggregation area 112 is 0mm-2.0mm, so that the aerosol-generating substrate 200 in the accommodating cavity 101 can be ensured to contact the liquid guiding member 111, so that the aerosol-generating substrate 200 can flow back to the heating element 13, waste caused by accumulation of the aerosol-generating substrate 200 in the accommodating cavity 101 is avoided, and the utilization rate of the aerosol-generating substrate 200 is improved.

Referring to fig. 2, 3, 4 and 9, in some embodiments, the atomizing base 11 further includes a liquid reservoir 114 disposed in the accommodating cavity 101, the liquid reservoir 114 being in communication with the aggregation area 112, the liquid reservoir 114 being configured to store the aerosol-generating substrate 200 in the accommodating cavity 101.

Specifically, in certain embodiments, the atomizing base 11 may include a plurality of first aggregation members 117 and a plurality of second aggregation members 118, each of the first aggregation members 117 and the second aggregation members 118 being located within the receiving chamber 101, the first aggregation members 117 being closer to the peripheral wall 110 of the atomizing base 11 than the second aggregation members 118. The first aggregation pieces 117 are arranged at intervals to form a plurality of first aggregation pieces 1171, the second aggregation pieces 118 are arranged at intervals to form a plurality of second aggregation pieces 1181, the first aggregation pieces 1171 and the second aggregation pieces 1181 are in one-to-one correspondence and are communicated with the aggregation area 112, the first aggregation pieces 1171 and the second aggregation pieces 1181 jointly form the liquid storage groove 114, and therefore the liquid storage groove 114 can prevent the aerosol-generating substrate 200 from freely flowing in the accommodating cavity 101, and the aerosol-generating substrate 200 can be well concentrated in the aggregation area 112, so that the backflow efficiency of the aerosol-generating substrate 200 is improved. Since the liquid guide 111 requires a certain time to guide the aerosol-generating substrate collected in the collecting region 112 to flow back to the heating element 13, the liquid storage tank 114 can slow down the flow rate of the aerosol-generating substrate 200 in the accommodating chamber 101, and prevent the aerosol-generating substrate 200 from rapidly collecting in the collecting region 112 and flowing out of the collecting region 112 due to the liquid level exceeding the height of the collecting region 112.

In certain embodiments, the cross-sectional area of the collection region 112 is 20mm ² -80 mm ² . Specifically, in certain embodiments, the cross-sectional area of the accumulation region 112 may be 20mm ² 、30mm ² 、40mm ² 、50mm ² 、60mm ² 、70mm ² 80mm ² Any one value or any number between any two values. If the cross-sectional area of the collection region 112 is less than 20mm ² To ensure that the liquid guide 111 extends into the collecting zone 112, the cross-sectional area of the liquid guide 111 needs to be relatively small, which results in a reduced flow rate of the back flow of the aerosol-generating substrate 200 per unit time, which in turn affects the back flow efficiency of the aerosol-generating substrate 200. If the cross-sectional area of the collection region 112 is greater than 80mm ² The number of aerosol-generating substrates 200 that can be aggregated in the aggregation zone 112 is excessive and in the event that a user draws, the aerosol-generating substrates 200 are easily drawn into the user's mouth, affecting the user's experience of drawing. In the present embodiment, however, the cross-sectional area of the collection region 112 is 20mm ² -80 mm ² On the one hand, this prevents a reduction in the flow rate of the aerosol-generating substrate 200, which would otherwise be caused by too small a cross-sectional area of the liquid guide 111, fromWhile ensuring the reflow efficiency of the aerosol-generating substrate 200; on the other hand, it is possible to avoid excessive aggregation of the aerosol-generating substrate 200 in the aggregation zone 112, resulting in an easy aspiration of the aerosol-generating substrate 200 into the mouth of the user in case of an aspiration by the user, thereby enhancing the user experience of the aspiration.

Referring to fig. 2 and 3, in some embodiments, the atomizing base 11 is provided with an air outlet channel 119, and the air outlet channel 119 communicates with the accommodating cavity 101. The atomizer 10 may further include a first sealing member 15, the first sealing member 15 being located between the heat generating body 13 and the top cover 115 for sealing a gap between the heat generating body 13 and the top cover 115.

Specifically, in certain embodiments, the gas outlet channel 119 extends through the top wall 1151 of the top cover 115 and communicates with the receiving cavity 101, the gas outlet channel 119 includes a first end 1191 and a second end 1193, the first end 1191 of the gas outlet channel 119 is located outside the top wall 1151 of the top cover 115, and the second end 1193 of the gas outlet channel 119 is located inside the top wall 1151 of the top cover 115 and communicates with the receiving cavity 101. Where the user draws on the aerosol-generating device 100 (shown in fig. 1), the aerosol-generating substrate 200 (shown in fig. 9) may be contacted by the heater 13, and the heater 13 heats the aerosol-generating substrate 200 to generate an aerosol, which is drawn by the user after flowing through the second end 1193 of the air outlet channel 119 and the first end 1191 of the air outlet channel 119 in sequence.

In certain embodiments, the first seal 15 is located on the side of the heat-generating body 13 facing the liquid storage chamber 33 and between the heat-generating body 13 and the top cover 115, thereby achieving a seal of the gap between the heat-generating body 13 and the top cover 115, preventing the aerosol-generating substrate 200 from entering the receiving chamber 101 through the gap between the heat-generating body 13 and the top cover 115, thereby reducing or even avoiding wastage of the aerosol-generating substrate 200. It should be noted that, in some embodiments, the first sealing member 15 may be made of rubber, silicone, plastic, or synthetic fiber. Among them, the rubber material includes, but is not limited to, natural rubber, nitrile rubber, fluororubber, urethane rubber, ethylene propylene diene rubber, silicone rubber, etc. When the first seal member 15 is made of a rubber material, the abutment between the first seal member 15 and the heat generating body 13 and the top cover 115 is tighter, so that the sealing effect of the first seal member 15 on the gap between the heat generating body 13 and the top cover 115 can be improved.

With continued reference to fig. 2 and 3, in some embodiments, the peripheral wall 1153 of the top cover 115 is provided with a first opening 1157 and a second opening 1158, both the first opening 1157 and the second opening 1158 are in communication with the accommodating cavity 101, the peripheral wall 1153 is further provided with a communication groove 1159, one end of the communication groove 1159 is in communication with the first opening 1157, and the other end is in communication with the liquid storage cavity 33.

Specifically, referring to fig. 4, in some embodiments, a bottom wall 1161 of the base 116 is provided with an air inlet hole 1167, and the air inlet hole 1167 communicates with the accommodating cavity 101. When a user sucks the aerosol-generating device 100 (shown in fig. 1), the aerosol-generating substrate 200 (shown in fig. 9) entering the accommodating chamber 101 and contacting the heating element 13 can be heated and atomized by the heating element 13 to generate aerosol, and the aerosol is sucked by the user, at this time, the air pressure in the accommodating chamber 101 gradually decreases to form a negative pressure state compared with the external air pressure, and if the external air cannot enter the accommodating chamber 101, the accommodating chamber 101 is always in the negative pressure state, so that the aerosol-generating substrate 200 in the liquid storage chamber 33 cannot continuously enter the accommodating chamber 101, thereby affecting the generation amount of the aerosol and the suction taste. In this application, the communicating groove 1159 is recessed from the outer side of the peripheral wall 1153 toward the center of the top cover 115, and two ends of the communicating groove 1159 are respectively communicated with the accommodating cavity 101 and the first opening 1157, so that in the case that the air pressure in the accommodating cavity 101 gradually decreases to form a negative pressure state compared with the external air pressure, the external air can enter the accommodating cavity 101 through the air inlet hole 1167 or enter the accommodating cavity 101 through the first opening 1157, so that the air pressure in the accommodating cavity 101 is the same as the external air pressure, the aerosol generating substrate 200 in the liquid storage cavity 33 can enter the accommodating cavity 101 and contact with the heating element 13, and the generation amount of the aerosol is further ensured.

In addition, the generated aerosol may be partially condensed to form condensate when contacting the peripheral wall 1153 of the cap 115, and the condensate may be able to enter the accommodating chamber 101 along the peripheral wall 1153 of the cap 115, so that it may not be reused. Therefore, in this embodiment of the present application, the atomizer 10 may further include a second sealing member 17, where the second sealing member 17 is sleeved on the outer side of the peripheral wall 1153 of the top cover 115 and is used to seal the first opening 1157, the second opening 1158 and the communication groove 1159, so that on one hand, generated aerosol can be prevented from leaking to the outside of the accommodating cavity 101 through the first opening 1157 and the second opening 1158, so that the internal structure of the aerosol generating device 100 (shown in the figure) is prevented from being polluted, the generated aerosol amount can be ensured, and the user suction experience is improved; on the other hand, in case that the user sucks the aerosol-generating device 100, the condensate formed by the aerosol can flow back into the liquid storage chamber 33 through the communicating groove 1159, so that the condensate can be heated and atomized again by the heating body 13 to generate the aerosol, thereby reducing or even avoiding the waste of the aerosol-generating substrate 200.

In some embodiments, the second seal 17 may be made of rubber, silicone, plastic, or synthetic fiber, among others. Among them, the rubber material includes, but is not limited to, natural rubber, nitrile rubber, fluororubber, urethane rubber, ethylene propylene diene rubber, silicone rubber, etc. When the second seal 17 is made of a rubber material, the abutment between the second seal 17 and the peripheral wall 1153 of the top cover 115 is tighter, so that the sealing effect of the second seal 17 against the first opening 1157, the second opening 1158 and the communication groove 1159 can be improved.

Referring to fig. 1, 3, 4 and 9, in some embodiments, the aerosol-generating device 100 may further comprise a detection member 40, the detection member 40 being capable of analyzing whether the aerosol-generating device 100 is being aspirated or not based on a change in air pressure. Specifically, in some embodiments, in the case that the user sucks the aerosol-generating device 100, the air pressure in the accommodating cavity 101 gradually decreases to a negative pressure compared to the external atmosphere, and the air pressure in the space where the detecting member 40 is located also decreases to the negative pressure, and in the case that the detecting member 40 detects the negative pressure, the detecting member 40 can control the heating body 13 to generate heat so that the aerosol-generating substrate 200 is heated to generate aerosol for the user to suck. In the case where the aerosol-generating device 100 is not being sucked, ambient air can enter the housing chamber 101 through the air inlet hole 1167 so that the air pressure in the housing chamber 101 returns to the same as the ambient atmosphere, and after the detecting member 40 detects a change in the air pressure, the detecting member 40 controls the heat generating member to stop generating heat.
