[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0004] Currently, aerosol generating devices transfer liquid matrix from the liquid storage chamber to a liquid-conducting member within the support member through a liquid-conducting hole provided in the support member. The liquid matrix is ​​then heated and atomized on the heating element in contact with the liquid-conducting member to produce an aerosol. However, the liquid-conducting holes in conventional support members have a relatively large diameter. After passing through the liquid-conducting holes, the liquid matrix is ​​stored in the liquid-conducting member. If the heating element does not promptly heat and atomize the liquid matrix, the liquid matrix is ​​likely to leak from the liquid-conducting member into the atomization chamber, and then leak out of the aerosol generating device through the air inlet passage, severely impacting the user experience.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or suggesting the quantity or order of the technical features indicated relative to importance or implicitly indicating the indicated technical features.

[0052] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0053] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0054] One embodiment of the present application provides an atomizer assembly 1, as shown in FIG1 , comprising: a liquid guide member 11, comprising a liquid guide surface 111 and a heating surface 112 disposed opposite each other, the liquid guide member 11 being configured to guide a liquid matrix from the liquid guide surface 111 to the heating surface 112; a heating element 12 disposed on the heating surface 112 and configured to atomize the liquid matrix to form an aerosol; a support member 13 having a first surface 130, the first surface 130 being in contact with the liquid guide surface 11, and at least a portion of the first surface 130 forming at least a portion of an aerosol flow channel; the support member 13 being provided with a plurality of micropores 131 for allowing the liquid matrix to pass through and enter the liquid guide member 11, the total area of ​​the micropores 131 being between 1.5 square millimeters and 15 square millimeters. The term "micropore" means having a characteristic size less than 1 millimeter and greater than 1 micron. The characteristic size refers to the minimum size of the micropore in a certain direction other than the depth direction of the pore. For example, if the micropore is a circular hole, the characteristic size is the diameter of the micropore; if the micropore is a square hole, the characteristic size is the minimum side length of the square hole; if the micropore is a long strip hole, the characteristic size is the width of the long strip hole, and so on.

[0055] The support member 13 of the atomizer assembly 1 provided in the present application is provided with a plurality of micropores 131, with a total area of ​​the plurality of micropores 131 ranging from 1.5 square millimeters to 15 square millimeters. This allows the support member 13 to maintain sufficient liquid inlet capacity while also limiting the rate at which liquid passes through the tube wall of the support member 13, thereby controlling the rate at which the liquid matrix enters the liquid-guiding member 11 and reducing the risk of liquid matrix leakage from the liquid-guiding member 11. Compared to the prior art, this design has the advantage that the outer surface of the support member 13 does not need to be coated with a capillary material used to control the liquid penetration rate. The support member 13 can be placed directly within the liquid storage chamber, with its outer surface directly contacting the liquid matrix, thereby allowing the liquid matrix to enter the micropores 131.

[0056] In one embodiment of the present application, the liquid guide member 11 may be liquid guide cotton or liquid guide ceramic, and the heating element 12 may be bonded to the surface of the liquid guide member 11 by printing, deposition, sintering, or physical assembly. In one embodiment of the present application, the heating element 12 is a heating sheet or a heating mesh, and the liquid guide member 11 is liquid guide cotton.

[0057] In one embodiment of the present application, as shown in Figures 3-7, micropores 131 include circular holes, elongated holes, or a combination thereof. In one embodiment of the present application, micropores 131 are linear elongated holes or curved elongated holes. The shape of micropores 131 can be determined based on design requirements, as long as it maintains sufficient liquid inlet capacity while also having a certain liquid retention capacity.

[0058] In one embodiment of the present application, as shown in Figures 3-4, the pore size of the micropore 131 refers to the size of the micropore in at least one direction. In one embodiment of the present application, the characteristic size of the micropore is 0.1 mm-0.95 mm. When the characteristic size of the micropore 131 is 0.1 mm-0.95 mm, the micropore 131 has a capillary effect, which can maintain a certain liquid inlet capacity while also having a certain liquid locking capacity. In one embodiment of the present application, the characteristic size of the micropore 131 is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 0.95 mm. In one embodiment of the present application, the characteristic size of the micropore 131 is preferably 0.2 mm-0.7 mm. In one embodiment of the present application, the more preferred characteristic size of the micropore 131 is 0.3 mm-0.5 mm. In one embodiment of the present application, the more preferred characteristic size of the micropore 131 is 0.3 mm-0.45 mm.

[0059] In one embodiment of the present application, the micropores 131 are arranged in an array. In one embodiment of the present application, the micropores 131 are circular holes and arranged in an array for ease of machining. In one embodiment of the present application, the micropores 131 are multiple parallel long straight holes. In one embodiment of the present application, the micropores 131 are long holes in the shape of an S-curve.

[0060] In one embodiment of the present application, the number of micropores 131 is greater than or equal to 5, so that the micropores 131 can maintain capillary action and have a certain liquid locking ability, while also allowing the total area of ​​the micropores to be maintained at a certain value, with a certain liquid conducting ability. In one embodiment of the present application, when the micropores 131 are circular holes or elliptical holes, the number of the micropores is greater than 20. In one embodiment of the present application, when the micropores 131 are circular holes or elliptical holes, the number of the micropores is greater than or equal to 30, or 40, or 50. In one embodiment of the present application, when the micropores 131 are circular holes or elliptical holes, the number of the micropores is not greater than 100. The provision of too many holes will cause an unacceptable increase in processing costs.

[0061] In one embodiment of the present application, as shown in FIG2 , the heating element 12 includes a first conductive electrode 121, a second conductive electrode 122, and a heating portion 123. The heating portion 123 is connected between the first conductive electrode 121 and the second conductive electrode 122, and the heating portion 123 is arranged corresponding to the micropores 131. In one embodiment of the present application, the heating element 12 also includes a first conductive wire 124 and a second conductive wire 125. The first conductive wire 124 is connected to the first conductive electrode 121, and the second conductive wire 125 is connected to the second conductive electrode 122. In one embodiment of the present application, the heating portion 123 refers to the portion of the heating element 12 located between the first conductive electrode portion 121 and the second conductive electrode portion 122, which is used to pass current and generate heat. The heating portion 123 heats the liquid matrix and atomizes it to produce an aerosol. Therefore, the liquid matrix in the liquid guide member 11 corresponding to the heating portion 123 is consumed faster. Therefore, the micropores 131 are arranged corresponding to the heating portion 123 so that the liquid matrix can be conducted to the heating portion 123 more quickly through the liquid guide member 11.

[0062] In one embodiment of the present application, as shown in FIG4 , the support member 13 is tubular and includes a first end 132, a second end 133 opposite the first end 132, and a middle section 134 located between the first and second ends 132, 133. The micropores 131 are located in the middle section 134. The liquid-conducting member 12 is sleeved within the support member 13. The micropores 131 located in the middle section 134 allow the micropores 131 to correspond with the liquid-conducting member 12 sleeved within the support member 13. This allows the liquid matrix to be absorbed by the liquid-conducting member after passing through the micropores 131 on the support member 13, thereby preventing leakage of the liquid matrix. In one embodiment of the present application, at least one end of the support member 13 has a positioning notch 135. The first and second conductive wires 124, 125 of the heating element 12 pass through the positioning notch 135 and exit the support member 13. The positioning notch 135 facilitates the first and second conductive wires 124, 125 from changing shape to connect to other conductive components. In one embodiment of the present application, the support member 13 is tubular, the liquid guide member 11 is also generally tubular, and the connecting line between the heating portion 123 and the micropores 131 is located in the radial direction of the support member 13 .

[0063] In one embodiment of the present application, the micropores 131 are unevenly distributed around the circumference of the support member 13. In one embodiment of the present application, the number of micropores 131 distributed at the first end 132 and the second end 133 is less than the number of micropores 131 distributed in the middle section 134. In one embodiment of the present application, the micropores 131 are distributed in the middle section 134, and the number of micropores 131 distributed in the middle section 134 is less near the first end 132 than far from the first end 132, or the number of micropores 131 near the second end 133 is less than the number far from the second end 133.

[0064] In one embodiment of the present application, as shown in FIG5 , the liquid-guiding member 11 is formed by winding a liquid-guiding sheet 113, with the end portions of the liquid-guiding sheet 113 facing each other to form an interface 114. The micropores 131 are circumferentially arranged away from the interface 114, so that the liquid matrix conducted from the micropores 131 to the liquid-guiding member 11 is away from the interface 114, thereby preventing the liquid matrix from leaking from the interface 114 of the liquid-guiding member 11. In one embodiment of the present application, the liquid-guiding sheet 113 is a liquid-guiding cotton sheet, and the liquid-guiding member 11 is formed by winding the liquid-guiding cotton sheet, with the end portions of the liquid-guiding cotton sheet facing each other to form the interface 114. In one embodiment of the present application, the number of liquid-guiding sheets 113 can be designed based on the desired liquid-guiding effect of the liquid-guiding member 11. For example, the number of liquid-guiding sheets 113 can be 4, 6, 8, etc. In some embodiments of the present application, when there are multiple liquid-guiding sheets 113, they can be made of the same material or different materials.

[0065] One embodiment of the present application provides an atomizer 10, as shown in FIG8 , comprising the above-mentioned atomizer assembly 1. In one embodiment of the present application, the atomizer 10 further comprises: a housing 2 for forming a liquid storage chamber 21 for storing a liquid matrix; a bracket 3, the bracket 3 being positioned within the housing 2 and constituting at least a portion of the boundary of the liquid storage chamber 21; one end of the atomizer assembly 1 being connected to the bracket 3, and the other end being connected to the housing 2; and micropores 131 being exposed to the liquid storage chamber 21. The liquid matrix in the liquid storage chamber 21 enters the liquid guide member 11 through the micropores 131 on the support member 13, and the liquid guide member 11 conducts the liquid matrix from the liquid guide surface 111 to the heating surface 112, and then, under the heating of the heating element 12, atomizes and forms an aerosol for the user to inhale.

[0066] In one embodiment of the present application, the housing 2 further includes an air tube 22. One end of the atomizer assembly 1 is connected to the bracket 3, and the other end is connected to the air tube 22 of the housing 2. The side of the heating element 12 facing away from the liquid guide 11 is an atomization chamber 126. The atomization chamber 126 is connected to the air tube. The liquid matrix atomized by the heating element 12 forms an aerosol in the atomizer 126, and the aerosol can be inhaled by the user through the air tube 22.

[0067] In one embodiment of the present application, an annular space 127 is provided between the bracket 3 and the support member 13. In one embodiment of the present application, the cross-sectional area of ​​the annular space 127 gradually decreases in the direction away from the liquid storage chamber 21, so that the liquid matrix in the liquid storage chamber 21 flows more easily from the liquid storage chamber 21 into the micropores 131. The annular space 127 has a diversion effect on the liquid matrix, and the utilization rate of the liquid matrix is ​​higher. In one embodiment of the present application, the cross-sectional area of ​​the annular space 127 remains substantially unchanged in the direction away from the liquid storage chamber 21. The projection of the annular space 127 on the center line of the atomizer assembly 1 is smaller than the projection area of ​​the liquid storage chamber 21 on the center line of the atomizer assembly 1, so that the liquid matrix is ​​more easily retained in the annular space 127, thereby improving the utilization rate of the liquid matrix.

[0068] In one embodiment of the present application, a seal 4 is further provided between the housing 2 and the bracket 3 , and the seal 4 is used to improve the sealing performance between the housing 2 and the bracket 3 and prevent the liquid matrix from leaking from between the housing and the bracket.

[0069] In one embodiment of the present application, as shown in Figures 8-11, the bracket 3 includes a first protrusion 31 and a base 34. The first protrusion 31 and the base 34 abut against the seal 4, thereby forming a buffer chamber 35. The first protrusion 31 is provided with a first guide channel 311, and the base 34 is provided with an air inlet 341. The air inlet 341 on the base 34 allows air to enter the buffer chamber 35. When the liquid matrix in the liquid storage chamber 21 decreases, the pressure of the air in the liquid storage chamber 21 decreases. The first guide channel 311 allows the air in the buffer chamber 35 to enter the liquid storage chamber 21, thereby balancing the air pressure in the liquid storage chamber 21 and the air in the buffer chamber 35, so that the liquid matrix in the liquid storage chamber 21 can flow smoothly into the atomizer assembly 1. On the other hand, the liquid matrix leaked from the liquid storage chamber 21 through the first guide channel 311 can be stored in the buffer chamber 35.

[0070] In one embodiment of the present application, the bracket 3 is provided with a first air inlet channel 36 and a second air inlet channel 37. The first air inlet channel 36 is disposed on the base 34 and communicates with the air inlet hole 341, allowing air to flow into the buffer chamber 35. The second air inlet channel 37 is located between the buffer chamber 35 and the atomizing chamber 261 and is used to guide air into the atomizing chamber 261. Air enters the buffer chamber 35 from the air inlet hole 341 through the first air inlet channel 36, then enters the atomizing chamber 261 through the second air inlet channel 37, thereby guiding the aerosol generated by the heating element 12 into the trachea 22. In one embodiment of the present application, the first air inlet channel 36 and the second air inlet channel 37 are disposed on opposite sides. After entering the buffer chamber 35 from the air inlet hole 341 through the first air inlet channel 36, the air then rotates 180 degrees within the buffer chamber 35 and enters the second air inlet channel 37, then enters the atomizing chamber 261 through the second air inlet channel 37, thereby guiding the aerosol generated by the heating element 12 into the trachea 22 for inhalation by the user.

[0071] In one embodiment of the present application, the bracket 3 also includes a second protrusion 32, which is located between the first protrusion 31 and the base 34, and the second protrusion 32 abuts against the seal 4. The buffer chamber 35 is divided into a first buffer chamber 351 and a second buffer chamber 352 by the second protrusion 32, and the second protrusion 32 is provided with a second guide channel 321, which allows air to pass through, thereby connecting the first buffer chamber 351 and the second buffer chamber 352. In one embodiment of the present application, the projections of the first guide channel 311 and the second guide channel 321 on the center line of the atomizer assembly 1 do not overlap, so that the liquid matrix leaked from the liquid storage chamber 21 through the first guide channel 261 can be stored in the first buffer chamber 351. When the liquid matrix in the first buffer chamber 351 accumulates to a certain amount, it will enter the second buffer chamber 352, thereby preventing the liquid matrix from leaking from the air inlet 341 through the first air inlet channel 36.

[0072] In one embodiment of the present application, the bracket 3 also includes a third protrusion 33, which is located between the second protrusion 32 and the base 34.
