After assembly, the atomizing chamber 44 is formed between the atomizing surface of the porous element 41 and the base 70.

[0106] In some embodiments, the base 70 is at least partially housed in the first electrode 21; the base 70 is mechanically connected with the holder 50. According to Figure 3 and Figure 4 As shown, the holder 50 is arranged with at least one or more positioning grooves 54 towards the distal end 50; the base 70 is arranged with at least one positioning protrusion 74; in assembly, the positioning protrusion 74 of the base 70 extends into the positioning groove 54 of the holder 50 for providing positioning in their assembly. After assembly, the positioning protrusion 74 of the base 70 extends into the positioning groove 54 of the holder 50 to prevent relative rotation of the base 70 and the holder 50.

[0107] In some embodiments, the base 70 is further arranged with an air inlet channel 71, which is defined by a ring-shaped wall 711 extending longitudinally in the base 70. The air inlet channel 71 provides a channel path for the air entering the atomizing chamber 44 from the air inlet 213. In Figure 5 and Figure 6 As shown, the air inlet channel 71 has a tapered shape; in particular in Figure 5 and Figure 6 As shown, the cross-sectional area of the air inlet channel 71 gradually decreases in the direction approaching the atomizing surface.

[0108] In embodiments, a condensate receiving cavity 75 is also defined within the base 70, formed or defined by the annular wall 711 and the inner surface of the base 70. The condensate receiving cavity 75 is configured to receive the aerosol condensate generated within the atomization chamber 44 or to receive the liquid substrate seeping from the atomization surface. In embodiments, the condensate receiving cavity 75 is arranged around the annular wall 711.

[0109] In embodiments, a lead wire through hole 72 is also arranged on the base 70; after assembly, the conductive lead wire 43 is connected to the electrode assembly 20 after passing through the lead wire through hole 72.

[0110] In embodiments, the atomizer 100 further comprises:

[0111] A ventilation passage R3 is provided to provide a passage path for external air to enter the liquid storage cavity 112, for balancing the pressure of the liquid storage cavity 112 with the outside. In embodiments, the ventilation passage R3 is communicated between the liquid storage cavity 112 and the atomization chamber 44; alternatively, the ventilation passage is extended from the atomization chamber 44 to the liquid storage cavity 112.

[0112] In use, when the negative pressure in the liquid storage cavity 112 gradually increases as the user consumes the liquid substrate within the liquid storage cavity 112, the ventilation passage R3 can provide a passage path for air to enter the liquid storage cavity 112 from the atomization chamber 44, to relieve the negative pressure in the liquid storage cavity 112. Alternatively, when the atomizer 100 is subjected to environmental testing or transported at high altitude, if the pressure in the liquid storage cavity 112 is greater or less than the outside pressure, the ventilation passage R3 communicates the liquid storage cavity 112 with the outside atmosphere, to balance their pressures.

[0113] In some embodiments, the ventilation passage R3 has a width or diameter of about 0.2-2.0 mm; which is advantageous to prevent the liquid substrate from seeping from the ventilation passage R3.

[0114] In some embodiments, the ventilation passage R3 is substantially formed on the bracket 50; alternatively, the ventilation passage R3 is at least partially formed between the bracket 50 and the second sealing element 30.

[0115] In particular according to Figure 8 As shown, the ventilation passage R3 comprises:

[0116] A first air groove 561 is arranged on the inner side surface of the holding cavity 57 in the longitudinal direction;

[0117] A second air groove 562 is formed or arranged on the upper side surface of the holding cavity 57; the second air groove 562 is bent;

[0118] A ventilation communication hole 563 is extended from the second air groove 562 to a liquid delivery passage 52.

[0119] In the arrangement, the air exchange passage R3 is in communication with the liquid storage cavity 112 through the air exchange communication hole 563; or, the air exchange passage R3 is in communication with the liquid storage cavity 112 through the port of the liquid delivery passage 52 defined by the air exchange communication hole 563 for air to enter the liquid storage cavity 112. In the arrangement, the air exchange passage R3 is in communication with the atomization chamber 44 through the first air groove 561; or, the air exchange passage R3 is in communication with the atomization chamber 44 through the port of the atomization chamber 44 defined by the first air groove 561 for air of the atomization chamber 44 to enter the air exchange passage R3.

[0120] In use, when the negative pressure in the liquid storage cavity 112 exceeds a predetermined threshold, air in the atomization chamber 44 enters the liquid delivery passage 52 through the first air groove 561, the second air groove 562 and the air exchange communication hole 563 in sequence, and then enters the liquid storage cavity 112 in the form of bubble outflow, thereby balancing the pressure of the liquid storage cavity 112.

[0121] In an embodiment, the nebulizer 100 has only one air exchange passage R3. In addition, the air exchange passage R3 is defined by the air exchange communication hole 563, and the air outlet port of the air exchange passage R3 is located on one side of the partition wall 55. In use, when air from the air exchange passage R3 enters the liquid storage cavity 112, bubble outflow is only formed in one liquid delivery passage 52 on one side of the partition wall 55, and bubble outflow is not formed in the liquid delivery passage 52 on the other side of the partition wall 55 at the same time, which is advantageous for avoiding the influence of air exchange bubble on liquid guidance in the two liquid delivery passages 52.

[0122] In an embodiment, the air exchange passage R3 bypasses or crosses the atomization assembly 40 and / or the second sealing element 30 in the longitudinal direction of the nebulizer 100. In an embodiment, the channel path of the air exchange passage R3 is bent in the longitudinal direction of the nebulizer 100.

[0123] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification, and further, those skilled in the art can make improvements or modifications according to the above description, and all these improvements and modifications shall fall within the protection scope of the appended claims of the present application.
