[0039] The atomizer 100 provided by the present application comprises a housing 10, a mounting seat 20, an atomizing core 30, a fixing member 40 and an electrical connection assembly 50. The housing 10 has a suction nozzle 11, a liquid storage cavity 12 and an atomizing channel 13. The liquid storage cavity 12 is used for storing a substrate to be atomized. Specifically, the atomizing channel 13 can be arranged at a central region of the housing 10, and the liquid storage cavity 12 is arranged around the atomizing channel 13. In the housing 10, one end of the atomizing channel 13 is communicated with the suction nozzle 11, and the other end of the atomizing channel 13 is communicated with a receiving cavity 14 formed by the housing 10. The suction nozzle 11 can be integrally formed with the housing 10, or the suction nozzle 11 and the housing 10 can be separately arranged and connected.

[0040] In an embodiment, as shown in Figure 3 and Figure 4 The mounting seat 20 has a liquid downward channel 213 and an atomizing cavity 201. The liquid downward channel 213 can be provided with a liquid downward opening 2110. The liquid downward opening 2110 is communicated with the liquid storage cavity 12, and the liquid downward channel 213 is communicated with the atomizing cavity 201 and the liquid storage cavity 12, so as to guide the substrate to be atomized in the liquid storage cavity 12 to the atomizing core 30 for atomization.

The other end of the atomizing channel 13 away from the suction nozzle 11 can be further communicated with the atomizing cavity 201. The aerosol generated by the atomizing core 30 heating the substrate to be atomized can enter the atomizing channel 13 through the atomizing cavity 201, and can further enter the suction nozzle 11 from the atomizing channel 13 and be inhaled by a user through the suction nozzle 11.

[0041] In an embodiment, the mounting seat 20 can be further provided with a sealing seat 23 at one end close to the atomizing channel 13 and the liquid storage cavity 12. The sealing seat 23 can seal the liquid storage cavity 12, so as to prevent the substrate to be atomized from leaking from the connection gap between the housing 10 and the mounting seat 20. It can be understood that the sealing seat 23 is also provided with a first through hole 231 communicated with the liquid downward channel 213, so that the substrate to be atomized only enters the liquid downward channel 213 through the first through hole 231.

[0042] In an embodiment, as shown in Figure 4 The atomization core 30 has an atomization surface 301 exposed in the atomization cavity 201 and a liquid suction surface 302 which can be partially exposed in the atomization cavity 201 or not. The atomization surface 301 is arranged non-perpendicularly to the central axis X of the atomizer 100, which can be understood as an imaginary center line extending from the top to the bottom of the atomizer 100. The non-perpendicular arrangement can be understood as parallel arrangement, cross arrangement, etc. The fixing member 40 is connected to the mounting seat 20 and abuts against the atomization surface 301. Specifically, the fixing member 40 can be fixedly connected or detachably connected to the mounting seat 20, as long as it can abut against the atomization surface 301 to fix the atomization core 30 in cooperation with the mounting seat 20.

[0043] In an embodiment provided in the present application, the fixing member 40 is detachably connected to the mounting seat 20, such as clamping, inserting, sliding connection, etc.

[0044] Further, the side wall of the mounting seat 20 has a slot 2111. It can be understood that the slot 2111 is arranged at a position of the side wall of the mounting seat 20 close to the atomization surface 301, so as to facilitate the abutment of the fixing member 40 against the atomization surface 301. In the present embodiment, a part of the fixing member 40 is embedded in the slot 2111, and the other part protrudes out of the slot 2111, and the part of the fixing member 40 protruding out of the slot 2111 abuts against the atomization surface 301 to fix the atomization core 30.

[0045] In an embodiment, as shown in Figures 2 to 6 The mounting seat 20 includes a top seat 21 and a bottom seat 22. The top seat 21 has a top wall 211 and a first side wall 212 connected to each other. A liquid inlet channel 213 extends from the top wall 211 to the side of the first side wall 212, which can be understood as the side close to the atomization core 30. The side of the first side wall 212 has a groove 2121, and at least part of the atomization core 30 is arranged in the groove 2121, such as embedded or clamped in the groove 2121. Further, a sealing layer 31 can be arranged at the connecting position of the atomization core 30 and the groove 2121, so as to improve the sealing effect of the connection between the atomization core 30 and the mounting seat 20 and prevent the leakage of the to-be-atomized substrate. The sealing layer 31 can be silica gel, rubber, etc. It can be understood that the sealing layer 31 can be annularly arranged at the connecting position of the liquid suction surface 302 and the liquid inlet channel 213 or a second through hole 2131 is arranged, so as to prevent the to-be-atomized substrate from affecting the atomization core 30. The top wall 211 has a slot 2111 which can accommodate at least part of the fixing member 40.

[0046] The base 22 comprises a bottom wall 221 and a second side wall 222 connected with each other; an outer surface of the second side wall 222 can be connected with the shell 10, for example, clamped, screwed, or the like. The base 22 is connected with the top base 21 to cooperatively form the atomization cavity 201; for example, the second side wall 222 of the base 22 and the first side wall 212 of the top base 21 can be annular to cooperatively form the atomization cavity 201. In the embodiment, the base 22 and the top base 21 can both be L-shaped, and in other embodiments, the base 22 and the top base 21 can also be other shapes, or can be integrally formed, which is not limited in the application. A sealing ring 24 can be arranged between the base 22 and the shell 10 to seal and reinforce, and the sealing ring 24 can be silica gel, rubber, or the like.

[0047] In an embodiment, as shown in Figures 3 to 5 , the bottom wall 221 of the base 22 is provided with an air inlet 2211, and the top wall 211 is provided with an air outlet 2112, which is in communication with the atomization channel 13; that is, the air entering from the air inlet 2211 can enter the atomization cavity 201, drive the aerosol in the atomization cavity 201 to pass through the air outlet 2112 into the atomization channel 13, and finally be inhaled by the user. The direction from the air inlet 2211 to the air outlet 2112 is defined as the airflow direction F, which is parallel to the central axis X and the arrangement direction of the atomization face 301. That is, in the embodiment, the atomization face 301 and the central axis X can be arranged in parallel. The airflow direction F can be the extension direction of the airflow path as shown in Figure 3 、 Figure 5 and Figure 8 .

[0048] In a specific embodiment, as shown in Figures 2 to 7 , the fixing member 40 can comprise a body part 41 and a protruding part 42, wherein the body part 41 is embedded in the slot 2111 provided in the top wall 211, and the protruding part 42 extends from the body part 41 towards the bottom wall 221, so that the fixing member 40 can form a structure similar to an L shape. The protruding part 42 abuts against one side of the atomization face 301 close to the mouthpiece 11 to fix the atomization core 30. It can be understood that in other embodiments, the fixing member 40 can also have other shapes, for example, rectangular, fan-shaped, triangular, and the like, wherein a part is embedded in the slot 2111, and the other part abuts against the atomization face 301, which can also achieve the fixing effect of the atomization core 30.

[0049] In an embodiment, as shown in Figures 2 to 9As shown, the electrical connection assembly 50 may include a first conductive electrode 51 and a second conductive electrode 52 spaced apart, which are spaced apart on the atomizing surface 301. Specifically, for example, the fixing member 40 may abut against the end of the atomizing surface 301 that is relatively close to the mouthpiece 11, while the first conductive electrode 51 and the second conductive electrode 52 are disposed at the end of the atomizing surface 301 that is relatively far away from the mouthpiece 11, thereby fixing both the upper and lower ends of the atomizer 100 along the usage direction of the atomizer 100 (i.e., the airflow direction F or the extension direction of the central axis X).
