The at least one capillary element 16 is used to receive the liquid matrix in the liquid storage chamber 113, and to adsorb and retain the received liquid matrix through the internal capillary structure or capillary pores. Of course, the at least one capillary element surrounds the tubular element 15 and covers the perforation 151. In use, the liquid matrix in the liquid storage chamber 113 is first transferred to the at least one capillary element 16 to be absorbed and retained, and then the liquid guiding element 17 indirectly absorbs the liquid matrix from the liquid storage chamber 113 from the at least one capillary element 16, for example Figures 4 to 15 As shown by the arrow R1.

One or more liquid conducting holes 131 surrounding the capillary element 16 are arranged on the second portion 134 of the support 13. Furthermore, the outer surface of the capillary element 16 is in fluid communication with the liquid storage chamber 113 through the liquid conducting holes 131, and can receive the liquid matrix passing through the liquid storage chamber 113; the inner surface of the capillary element 16 surrounds the tubular element 15 and covers the perforation 151, and thus the liquid conducting element 17 can indirectly absorb the liquid matrix from the liquid storage chamber 113 from the capillary element 16; Figures 4 to 15 As shown by the arrow R1.

[0102] See also Figure 3 to Figure 4As shown, the capillary element 16 is flexible; after assembly, the flexible capillary element 16 is radially squeezed or compressed by the second portion 134 of the support 13 and the tubular element 15 from the inner and outer sides respectively, so that the capillary element 16 is stably restricted and retained between the second portion 134 of the support 13 and the tubular element 15, which is beneficial for improving the liquid locking of at least one capillary element, such as the capillary element 16.

[0103] according to Figures 3 to 15 As shown, after assembly, the upper surface of the capillary element 16 axially abuts against the inner support wall 1341 .

[0105] The first partition space 135 is formed or defined along the axial direction between the upper surface of the capillary element 16 and the bracket 13; specifically, the inner support wall 1341 and the second part 134 of the bracket 13 are arranged at intervals in the radial direction; so that when the upper surface of the capillary element 16 axially abuts against the inner support wall 1341, the upper surface of the capillary element 16 closes the gap between the inner support wall 1341 and the second part 134 of the bracket 13, thereby forming the first partition space 135.

[0106] In the embodiment, the support 13 further defines a second space 136 formed or defined along the axial direction between the lower surface of the capillary element 16 and the lower end of the second portion 134 / the base 14, so that the lower surface of the capillary element 16 is non-contacting with the base 14, thereby preventing the liquid matrix adsorbed and retained in the capillary element 16 from seeping toward the surface of the base 14 by contact.

[0107] according to Figures 4 to 16 As shown in the figure, the inner surface of the second part 134 of the bracket 13 is also arranged with one or more air connecting grooves 1343 extending longitudinally; the air connecting grooves 1343 basically span the capillary element 16 longitudinally; and then after assembly, the first partition space 135 and the second partition space 136 are connected by air flow through the air connecting grooves 1343.

[0108] In some embodiments, the atomizer 1 further comprises: an airflow channel for providing an airflow path from the air inlet 122 via the atomization assembly to the air outlet 112 during inhalation, thereby outputting the aerosol to the air outlet 112. In an embodiment, the complete airflow channel is defined by a plurality of components.

[0109] Specifically according to Figures 4 to 15As shown by the middle arrow R2, the complete airflow path during inhalation includes: the air entering from the air inlet 122 passes through the base 14 and the lead isolation element 19 to the atomizer assembly / heating element 18, and carries the aerosol generated by the heating element 18 to be output from the air pipe 114 to the air outlet 112 to be inhaled by the user. Figures 2 to 9 As shown, there is a gap between the rear cover 12 and the base 14 after assembly, and the gap between them forms or defines a condensate storage chamber for storing aerosol condensate flowing out of the base 14 from the air flow channel, or preventing aerosol condensate in the air flow channel from flowing directly from the base 14 to the air inlet 122. Figure 4 and Fig.15 As shown in FIG. 1 , after assembly, the air tube 114 and the tubular element 15 / the liquid-conducting element 17 are arranged at intervals, and the bracket 13 assembles them to form an air flow connection.

[0110] In some embodiments, the atomizer 1 further comprises: a ventilation channel for providing a channel path for air to enter the liquid storage chamber 113 when the negative pressure in the liquid storage chamber 113 exceeds a predetermined threshold. Figure 4 , Fig.15 and Fig.16 As shown, the ventilation channel includes:

[0111] The first ventilation groove 132 is formed on the outer surface of the second portion 134 of the bracket 13, and extends from the lower end of the second portion 134 into the liquid storage chamber 113. A portion of the first ventilation groove 132 is surrounded and covered from the outside by the base 14; and a portion of the first ventilation groove 132 extends to the base 14 and is exposed outside the base 14. The first ventilation groove 132 is in fluid communication with the liquid storage chamber 113 through the portion exposed outside the base 14. The first ventilation groove 132 provides a channel path that connects the liquid storage chamber 113 with the second partition space 136.

[0112] according to Figure 4 , Fig.15 and Fig.16 As shown, the ventilation channel also includes:

[0113] The second ventilation groove 1342 is formed or defined on the inner surface of the inner support wall 1341 of the bracket 13, and is arranged along the axial extension of the inner support wall 1341; and the extension length of the second ventilation groove 1342 is greater than the length of the tubular element 15 inserted into the inner support wall 1341; then after assembly, a part of the second ventilation groove 1342 is closer to the first part 133 of the bracket 13 than the tubular element 15, and is not covered by the tubular element 15; a part of the second ventilation groove 1342 is covered by the tubular element 15. The part of the second ventilation groove 1342 that is staggered from the tubular element 15 is connected to the air flow channel. The second ventilation groove 1342 is defined with a notch at the end of the inner support wall 1341 that abuts against the upper surface of the capillary element 16, so that in use, the second ventilation groove 1342 connects the first spacing space 135 with the air flow channel. Alternatively, the portion of the ventilation channel defined by the second ventilation groove 1342 is formed or defined between the tubular element 15 and the inner support wall 1341 of the bracket 13. Thus, the ventilation channel flows through the upper surface of the capillary element 16.

[0114] In the embodiment, the ventilation channel is connected to the air flow channel, so that the air in the air flow channel can enter the liquid storage chamber 113 through the ventilation channel to relieve the pressure in the liquid storage chamber 113. For a complete ventilation path, see Figures 4 to 15 As shown in , they include:

[0115] When the negative pressure in the liquid storage chamber 113 exceeds a predetermined threshold, air is blown from the air flow channel through the second ventilation groove 1342 into the first partition space 135. Figure 4 and Fig.16 As indicated by the middle arrow R31;

[0116] The air in the first compartment 135 then flows to the second compartment 136 through the air communication groove 1343. Fig.16 As indicated by the middle arrow R32;

[0117] The air in the second partition space 136 then enters the liquid storage chamber 113 through the first ventilation groove 132. Fig.15 and Fig.16 As shown by the middle arrow R33 , the negative pressure in the liquid storage chamber 113 is relieved.

[0118] In some embodiments, an annular groove 1431 is arranged on the surface of the base 14 facing the bracket 13, and the annular groove 1431 surrounds the tubular element 15; and the annular groove 1431 is spaced from the lower end of the second portion 134 of the bracket 13. After assembly, the annular groove 1431 at least partially defines a liquid collection space 141 adjacent to or in communication with the first ventilation groove 132; the liquid collection space 141 is used to store the liquid matrix seeping out through the first ventilation groove 132.

[0119] In use, when the pressure in the liquid storage chamber 113 is greater than the external pressure, the liquid matrix in the liquid storage chamber 113 can flow into the liquid collection space 141 through the first ventilation groove 132, and be adsorbed and retained in the liquid collection space 141; and when the pressure in the liquid storage chamber 113 is less than the external pressure, such as during air transportation or product testing, the liquid matrix that has flowed into the liquid collection space 14 flows back to the liquid storage chamber 113 through the infiltration of the first ventilation groove 132. The first ventilation groove 132 has a depth or width of about 0.5 to 3.0 mm.

[0120] In some specific embodiments, the first ventilation groove 132 is constructed as a plurality of capillary grooves arranged at intervals along the circumference of the bracket 13, and the width thereof is between 0.2 mm and 2 mm. Under the action of negative pressure, the liquid matrix buffered in the liquid collection space 141 can be adsorbed and refluxed into the liquid storage cavity 113 by capillary force, so that the liquid matrix buffered in the liquid collection space 141 can be reused.

[0121] See also Figure 4 , Figure 7 As shown, the base 14 includes a side wall 142 surrounding at least a portion of the outside of the bracket 13, and at least a portion of the first ventilation groove 132 is exposed on the side wall 142, so that the first ventilation groove 132 can be connected to the liquid storage chamber 113, and the external air can enter the liquid storage chamber 113 through the ventilation channel; similarly, the liquid guide hole 131 is exposed on the side wall 142, so that the liquid guide hole 131 can be connected to the liquid storage chamber 113, so that the liquid matrix in the liquid storage chamber 113 can flow through.

[0122] The base 14 accommodates at least a portion of the support 13 near the distal end 111, and the base 14 cooperates with the bottom of the support 13 to define a liquid collection space 141 for caching liquid matrix; at least a portion of the ventilation channel is also defined between the support 13 and the base 14 to provide a flow path for air to enter the liquid storage chamber 113; when the negative pressure in the liquid storage chamber 113 exceeds the threshold, external air can enter the liquid storage chamber 113 through the ventilation channel to relieve the negative pressure. Based on this, at least a portion of the fluid of the ventilation channel connects the liquid storage chamber 113 and the liquid collection space 141, so that the liquid collection space 141 can cache the liquid matrix that seeps out of the ventilation channel to avoid contamination caused by the outflow of the liquid matrix; under the action of negative pressure, the liquid matrix cached in the liquid collection space 141 can also flow back to the liquid storage chamber 113 through the ventilation channel, so that these liquid matrices can be reused to improve the utilization rate of the liquid matrix.

[0123] For further information, see Figure 8As shown, the base 14 also includes a bottom support 143 for supporting the bottom of the bracket 13 upward, and the liquid collection space 141 includes an annular groove 1431 opened on the bottom support 143 and arranged circumferentially along the bottom support 143. The annular groove 1431 is located below the bottom of the first ventilation groove 132 and is used to collect the liquid matrix flowing out of the first ventilation groove 132.

[0124] For details, please refer to Figure 4 , Figure 7 , Figure 8 As shown, at least part of the second part 134 is accommodated in the base 14, and a liquid collecting space 141 for caching the liquid matrix is ​​defined between the bottom of the second part 134 and the base 14; the side wall 142 of the base 14 surrounds at least part of the outside of the second part 134, and the liquid guide hole 131 arranged on the second part 134 is exposed on the side wall 142, so that the liquid guide hole 131 is connected with the liquid storage cavity 113; one end of the first ventilation groove 132 arranged on the second part 134 is exposed on the side wall 142 to connect with the liquid storage cavity 113, and the other end is connected with the liquid collecting space 141, thereby forming a part of the ventilation channel, so as to balance the air pressure of the liquid storage cavity 113, and the liquid matrix cached in the liquid collecting space 141 can be refluxed and reused through the ventilation groove.

[0125] according to Fig.16 As shown, the first portion 133 of the bracket 13 further has an abutment portion 137; after assembly, the air pipe 114 and / or the sealing element 115 extend into the first portion 133 of the bracket 13 and abut against the abutment portion 137. In the embodiment, the abutment portion 137 is provided with a plurality of sawtooth-shaped protruding teeth 1372, and capillary gaps are formed between the plurality of protruding teeth 1372 to absorb aerosol condensate in the airflow channel, especially aerosol condensate falling from the air pipe 114.

[0126] The abutment portion 137 is also provided with a condensate guiding structure 1371 extending into the air pipe 114; Fig.16 It is arranged in the form of a ridge; after assembly, the condensate guiding structure 1371 at least partially extends into the air pipe 114, and can directly abut the inner surface of the air pipe 114, or not contact the inner surface of the air pipe 114 but form a capillary gap between the air pipe 114, thereby guiding the aerosol condensate in the air pipe 114 to the capillary gap between the convex teeth 1372 by contact or capillary adsorption, which is beneficial for preventing the aerosol condensate from being inhaled by the user.

Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
