[0028] In some embodiments, please refer to Figure 4 , the suction nozzle channel 25 has an inlet 251 and an outlet 252, the inner side wall 20 at the end of the inlet 251 of the suction nozzle channel 25 is used for sealingly matched with the outlet of the atomization chamber 6 in the atomization device, the inlet 251 of the suction nozzle channel 25 can be in communication with the atomization channel 61 in the atomization chamber 6, and the end of the outlet 252 of the suction nozzle channel 25 can be located outside the atomization device, the user's lips can be wrapped around the outer peripheral surface of the outer side wall 21 at the end of the outlet 252 of the suction nozzle channel 25 to receive the aerosol discharged from the outlet 252 of the suction nozzle channel 25.

[0029] In some embodiments, the carrier plate 3 can be arranged in the receiving cavity 26, and the carrier plate 3 can be interference-fitted with the cavity wall of the receiving cavity 26 to achieve fixed connection of the carrier plate 3 with the suction nozzle 2.

[0030] In some embodiments, please continue to refer to Figure 4 , the carrier plate 3 can also be arranged on the side of the receiving cavity 26 facing away from the outlet 252 of the suction nozzle channel 25 in the extension direction of the suction nozzle channel 25, the carrier plate 3 can be clamped and fixed between the atomization chamber 6 and the suction nozzle 2, or the carrier plate 3 can also be clamped and fixed on the suction nozzle 2 or the atomization chamber 6.

[0031] The carrier plate 3 of the embodiments of the present application is connected with a metal sheet 5, the metal sheet 5 is used for electrical connection with a control module 7 in an atomization device, and the carrier plate 3 can be a glass fiber carrier plate or a circuit board. As an embodiment, please refer to Figures 2 to 4The carrier plate 3 is a glass fiber carrier plate, and the carrier plate 3 is mainly used for supporting the carrier metal sheet 5. The carrier plate 3 is used for electrical connection with a control module 7 in the atomization device. The control module 7 includes a circuit board assembly for controlling the atomization core 67 to start or stop heating. In another embodiment, the metal sheet 5 is electrically connected with the carrier plate 3. The carrier plate 3 includes a circuit board. The carrier plate 3 supports the carrier metal sheet 5. The carrier plate 3 forms part of the control module 7 in the atomization device. The carrier plate 3 is also electrically connected with the atomization core 67 in the atomization device to control the atomization core 67 to work.

[0032] In some embodiments, the metal sheet 5 can be formed by processing a copper sheet. The metal sheet 5 extends into the accommodating cavity 26 in the direction in which the suction nozzle channel 25 extends. Please refer to Figure 4 One end of the metal sheet 5 is connected with the carrier plate 3. The metal sheet 5 is not directly embedded or embedded in the outer side wall 21. The metal sheet 5 is not directly connected with the outer side wall 21. The metal sheet 5 is only located between the outer side wall 21 and the inner side wall 20 of the suction nozzle and is in contact with the inner surface of the outer side wall 21.

[0033] In another embodiment, a slot can also be provided on the inner surface of the outer side wall 21. During installation, part of the metal sheet 5 is inserted into the slot. The depth of the slot is slightly greater than or equal to the thickness of the metal sheet 5 in the direction perpendicular to the inner surface of the outer side wall 21. The metal sheet 5 is in interference fit with the slot to ensure that the metal sheet 5 is in contact with the inner surface of the outer side wall 21.

[0034] In the embodiment of the suction nozzle assembly of the present application, when the user's lips are in contact with the outer circumferential surface of the outer side wall 21, the user's lips and the metal sheet 5 are isolated by the outer side wall 21. The user's lips and the metal sheet 5 will generate a capacitance change. An IC can be provided on the carrier plate 3. The IC can preliminarily detect the capacitance change signal between the metal sheet 5 and the user's lips, that is, detect that the user's lips are in contact with the outer circumferential surface of the outer side wall 21 of the suction nozzle. The capacitance change signal is transmitted to the control module 7. The control module 7 controls the atomization core 67 in the atomization device to start heating. When the user's lips are not in contact with the outer circumferential surface of the outer side wall 21, the IC does not detect the capacitance change signal generated on the metal sheet 5. The control module 7 controls the atomization core 67 to stop heating.

[0035] Thus, the control module 7 in the mouthpiece assembly and the atomization device of the embodiment of the present application cooperates with the atomization core 67, and can control whether the atomization core 67 works by detecting whether the user's lips contact the outer circumferential surface of the outer side wall 21 of the mouthpiece. Compared with the structure of controlling the atomization core 67 to work by detecting the change of airflow, the structure of detecting whether the user's lips contact the outer circumferential surface of the outer side wall 21 of the mouthpiece in the embodiment of the present application is not affected by whether the atomization device leaks, which helps to improve the control reliability of the atomization device on the atomization core 67. Moreover, the part of the metal sheet 5 that contacts the outer side wall 21 of the mouthpiece 2 is located in the accommodation cavity 26, and the accommodation cavity 26 is independent of the mouthpiece channel 25 through the sealing cooperation of the inner side wall 20 and the atomization cartridge 6, which can reduce the probability of aerosol or atomized liquid entering the space where the carrier plate 3 is located and penetrating into the carrier plate 3 or adhering to the metal sheet 5, and helps to further improve the control reliability of the atomization device on the atomization core 67.

[0036] In some embodiments, referring to Figure 4 , the metal sheet 5 has a connecting section 51 and a cantilever section 52 arranged in the extension direction of the mouthpiece channel 25, the connecting section 51 is connected with the carrier plate 3, and the cantilever section 52 is located in the accommodation cavity 26, and the cantilever section 52 can contact the inner surface of the outer side wall 21.

[0037] In an embodiment, a slot can be provided on the inner surface of the outer side wall 21 of the mouthpiece 2, and the metal sheet 5 can be located in the slot. During installation, the cantilever section 52 of the metal sheet 5 is inserted from one end of the slot, and the depth of the slot in the direction perpendicular to the inner surface of the outer side wall 21 of the mouthpiece 2 is slightly greater than or equal to the thickness of the metal sheet 5, so that after the metal sheet 5 is inserted into the slot, the metal sheet 5 can contact the inner surface of the outer side wall 21 of the mouthpiece 2.

[0038] In some embodiments, referring to Figure 4 , the metal sheet 5 can also be in elastic contact with the inner surface of the outer side wall 21 of the mouthpiece 2. The inner surface of the outer side wall 21 of the mouthpiece 2 gradually approaches the inner side wall 20 of the mouthpiece from the inlet 251 to the outlet 252 of the mouthpiece channel 25, so that the inner surface of the outer side wall 21 of the mouthpiece 2 is in the form of an inclined surface, an arc surface or a curved surface, and the metal sheet 5 can be a bent arc-shaped sheet structure.

[0039] The cantilever section 52 of the metal sheet 5 has a cantilever end 521 away from the connecting section 51 in the extending direction of the metal sheet 5, and the inner surface of the outer side wall 21 of the suction nozzle 2 can interfere with the cantilever end 521 of the metal sheet 5 during the insertion of the metal sheet 5 into the accommodating cavity 26. As the metal sheet 5 gradually extends into the accommodating cavity 26, the inner surface of the outer side wall 21 of the suction nozzle 2 can elastically abut against the cantilever section 52 of the metal sheet 5 to press the cantilever section 52 towards the direction of the suction passage 25. After the metal sheet 5 and the suction nozzle 2 are assembled in place, the metal sheet 5 elastically contacts the inner surface of the outer side wall 21 of the suction nozzle 2. This can improve the contact reliability between the metal sheet 5 and the inner surface of the outer side wall 21 of the suction nozzle 2, reduce the probability of increasing the gap between the metal sheet 5 and the outer side wall 21 of the suction nozzle 2 due to dropping or external force knocking, ensure the sensitivity of the capacitance change between the metal sheet 5 and the user's lips when the user's lips contact the outer peripheral surface of the outer side wall 21 of the suction nozzle, help improve the detection reliability of whether the user's lips contact the outer peripheral surface of the outer side wall 21 of the suction nozzle, and thus improve the control sensitivity of the atomization device on the atomization core 67 and the control reliability of the atomization device on the atomization core 67.

[0040] In an embodiment, after the metal sheet 5 and the suction nozzle 2 are assembled in place, only the cantilever end 521 of the metal sheet 5 can elastically contact the inner surface of the outer side wall 21 of the suction nozzle 2, or the cantilever end 521 of the metal sheet 5 can also be suspended in the accommodating cavity 26, and the cantilever section 52 of the metal sheet 5 connected between the cantilever end 521 and the connecting section 51 elastically contacts the inner surface of the outer side wall 21 of the suction nozzle 2.

[0041] In an embodiment, please continue to refer to Figure 4 The cantilever section 52 of the metal sheet 5 has a contact surface elastically fitted with the inner surface of the outer side wall 21 of the suction nozzle 2. Under the extrusion of the inner surface of the outer side wall 21 of the suction nozzle 2, the metal sheet 5 elastically bends at the connecting position of the cantilever section 52 and the connecting section 51, so that the side wall surface of the cantilever section 52 away from the suction passage 25 is pressed against the inner surface of the outer side wall 21 of the suction nozzle 2. This can increase the contact area between the outer side wall 21 of the suction nozzle 2 and the metal sheet 5, and improve the contact reliability between the metal sheet 5 and the outer side wall 21 of the suction nozzle 2.

[0042] The cantilever end 521 of the cantilever section 52 of the metal sheet 5 also elastically abuts against the inner side wall 20 of the suction nozzle 2. Under the elastic abutting action of the inner side wall 20 of the suction nozzle 2 on the cantilever end 521 of the metal sheet 5, the area of the elastic contact between the cantilever section 52 and the outer side wall 21 of the suction nozzle 2 can be further increased, the probability of increasing the gap between the metal sheet 5 and the outer side wall 21 of the suction nozzle 2 due to dropping or external force knocking can be further reduced, the detection reliability of whether the user's lips contact the outer side wall 21 of the suction nozzle 2 can be further improved, and the control reliability of the atomization device on the atomization core 67 can be further improved.

[0043] In an embodiment, please continue to refer to Figure 4In the extension direction of the suction nozzle channel 25, the distance between the outer side wall 21 of the suction nozzle 2 and the inner side wall 20 of the suction nozzle 2 gradually decreases from the inlet 251 of the suction nozzle channel 25 to the outlet 252 of the suction nozzle channel 25, and the outer side wall 21 of the suction nozzle 2 gradually inclines to the direction of the suction nozzle channel 25 from the inlet 251 of the suction nozzle channel 25 to the outlet 252 of the suction nozzle channel 25, so that the outer side wall 21 of the suction nozzle 2 forms an arc-shaped or inclined side wall. As the metal sheet 5 extends into the accommodation cavity 26, the interference amount of the outer side wall 21 of the suction nozzle 2 to the metal sheet 5 gradually increases, and the elastic pressure of the outer side wall 21 of the suction nozzle 2 to the metal sheet 5 gradually increases, which can increase the fitting elastic force between the outer side wall 21 of the suction nozzle 2 and the metal sheet 5, and improve the fitting reliability of the metal sheet 5 and the outer side wall 21 of the suction nozzle 2.

[0044] The cantilever section 52 of the metal sheet 5 is fitted with the outer side wall 21 of the suction nozzle 2, and the cantilever end 521 of the metal sheet 5 is in contact with the inner side wall 20 of the suction nozzle 2 and the outer side wall 21 of the suction nozzle 2 at the same time, so that the inner side wall 20 of the suction nozzle 2 forms a blocking action to the metal sheet 5, avoiding the generation of gaps between the metal sheet 5 and the outer side wall 21 of the suction nozzle 2 due to falling, external force knocking and other reasons, thereby further improving the control reliability of the atomization device to the atomization core 67.

[0045] Some users like to contact only one side of the outer side wall 21 of the suction nozzle 2 with the lip during the use of the atomization device. In order to avoid heating of the atomization core 67 during the use of the atomization device, in some embodiments, please refer to Figure 4 The outer side wall 21 of the suction nozzle assembly can be provided with a first side wall 23 and a second side wall 24 arranged opposite in a plane perpendicular to the extension direction of the suction nozzle channel 25, and two metal sheets 5 are further provided, and the two metal sheets 5 are respectively in corresponding contact with the inner surfaces of the first side wall 23 and the second side wall 24.

[0046] The carrier plate 3 can be provided with two carrier plates 3, and the two metal sheets 5 are arranged one by one, the metal sheet 5 is arranged on the corresponding carrier plate 3, and the metal sheet 5 is electrically connected with the corresponding carrier plate 3; or please refer to Figure 2 and Figure 4The two metal sheets 5 can be arranged on the same carrier plate 3 and electrically connected to the same carrier plate 3. The two metal sheets 5 are arranged in parallel and spaced apart in a plane perpendicular to the extension direction of the suction nozzle channel 25. When the first side wall 23 and the second side wall 24 are in contact with the upper and lower lips of the user, respectively, the two metal sheets 5 can generate capacitance changes between the two metal sheets 5 and the upper and lower lips of the user. The two capacitance change signals can be transmitted to the control module 7 of the atomization device. The control module 7 can be configured to control the heating of the atomization core 67 only when the two capacitance change signals are transmitted to the control module 7. That is, the atomization core 67 can be heated only when the upper and lower lips of the user are in contact with the outer surfaces of the first side wall 23 and the second side wall 24 of the outer side wall 21 of the suction nozzle 2. This can prevent the atomization core from being heated by mistake and improve the reliability of the control of the atomization device on the atomization core 67.

[0047] In other embodiments, it can be specified that when the atomization device is used, the user is prevented from contacting only one side of the outer side wall 21 of the suction nozzle 2 with the lips or other parts of the body. In this way, only one metal sheet 5 can be provided, and the metal sheet 5 can be in contact with only the inner surface of the first side wall 23 or the inner surface of the second side wall 24. In this way, the atomization core 67 can be started by the control module 7 when the lips of the user are wrapped around the outer surfaces of the first side wall 23 and the second side wall 24 of the suction nozzle 2 in the arrangement direction of the first side wall 23 and the second side wall 24. This improves the reliability of the control of the atomization device on the atomization core 67.

[0048] In some embodiments, as shown in FIG. 1, the atomization device can include a suction nozzle 2, a carrier plate 3, a metal sheet 5, a control module 7, and an atomization core 67. Figures 2 to 4 The suction nozzle 2 can be in a thin-walled shell structure, and the accommodation cavity 26 can be arranged around the suction nozzle channel 25. The carrier plate 3 can be provided with a through hole through which the inner side wall 20 of the suction nozzle 2 passes. In this way, the carrier plate 3 is also arranged around the suction nozzle channel 25, so that the two metal sheets 5 can be connected to the same carrier plate 3.

[0049] In other embodiments, the accommodation cavity 26 can be provided with two accommodation cavities 26 arranged on both sides of the suction nozzle channel 25 in the arrangement direction of the first side wall 23 and the second side wall 24. The metal sheet 5 and the carrier plate 3 can also be provided with two metal sheets 5 and two carrier plates 3, respectively. One accommodation cavity 26 corresponds to one metal sheet 5 and one carrier plate 3.

[0050] In some embodiments, as shown in FIG. 1, the atomization device can include a suction nozzle 2, a carrier plate 3, a metal sheet 5, a control module 7, and an atomization core 67. Figure 3 The carrier plate 3 can be located on the side of the accommodation cavity 26 away from the outlet 252 of the suction nozzle channel 25 in the extension direction of the suction nozzle channel 25. The outer side wall 21 of the suction nozzle 2 can be provided with a notch 22 at the end away from the outlet 252 of the suction nozzle channel 25 in the extension direction of the suction nozzle channel 25. The outer side wall 21 of the suction nozzle 2 and the carrier plate 3 form a wire passage 4 at the notch 22, and the external wire 31 of the carrier plate 3 for electrical connection with the control module 7 can pass through the wire passage 4.

[0051] In some other embodiments, a notch may be provided on the carrier plate 3 near the edge. The notch on the carrier plate 3 and the notch on the outer wall 21 of the suction nozzle 2 enclose each other to form a wire passage 4, through which the external wire 31 passes.

[0052] This application also provides an atomizing device, please refer to... Figures 1 to 4 The atomizing device includes a housing 1, an atomizing chamber 6, and a mouthpiece assembly as described in any of the above embodiments. The atomizing chamber 6 is located inside the housing 1. The mouthpiece 2 in the mouthpiece assembly can be connected to the housing 1. One end of the mouthpiece 25 with outlet 252 is located outside the housing 1, and the other end of the mouthpiece 25 with inlet 251 is located inside the housing 1. The mouthpiece 2 and the housing 1 can be connected by snap-fit, or the end of the mouthpiece 25 with inlet 251 is press-fitted and fixed between the atomizing chamber 6 and the housing wall of the housing 1, thereby achieving a fixed connection between the mouthpiece 2 and the housing 1.

[0053] The atomizing chamber 6 has an outlet that communicates with the atomizing channel 61. The inner wall 20 of the mouthpiece 2 is sealed and inserted into the outlet of the atomizing chamber 6 at the end where the inlet 251 of the mouthpiece channel 25 is located. The atomizing chamber 6 may include a cylinder 62 that extends in the extension direction of the mouthpiece channel 25. The openings at both ends of the cylinder 62 are sealed by sealing members 63. The outlet of the atomizing chamber 6 may be located on the sealing member 63 at one end of the cylinder 62. The inner wall 20 of the mouthpiece 2 may be inserted into the sealing member 63 to achieve a sealed fit between the inner wall 20 of the mouthpiece 2 and the atomizing chamber 6, so as to achieve communication between the mouthpiece channel 25 and the atomizing channel 61 in the atomizing chamber 6. At the same time, it also separates the mouthpiece channel 25 on the mouthpiece 2 from the receiving cavity 26, so that the mouthpiece channel 25 and the receiving cavity 26 are relatively independent.
