[0001] Cross-reference of related applications

[0002] This application claims priority to Chinese Utility Model Patent Application No. 2024232080244, filed on December 25, 2024, entitled "A Mouthpiece Assembly and Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, specifically to mouthpiece assemblies and atomizing devices. Background Technology

[0004] Atomizing devices typically use an atomizing core to heat the atomizing liquid to generate an aerosol. Currently, most in the industry use airflow sensors to detect the user's inhalation action. The control module is electrically connected to the airflow sensor, and the control module can control the atomizing core to start or stop heating based on the detection results of the airflow sensor.

[0005] In structures that detect a user's inhalation action using an airflow sensor, the airflow sensor is usually placed at the location with the fastest airflow velocity in the atomizer, or directly connected to the mouthpiece, to improve the sensitivity of the airflow sensor. However, when the atomizer leaks air, it reduces the sensitivity of the airflow sensor, resulting in poor reliability of the atomizer's control over the atomizer core. Summary of the Invention

[0006] This application provides a mouthpiece assembly and an atomizing device to solve the technical problem of poor control reliability of the atomizing device over the atomizing core.

[0007] According to a first aspect, one embodiment provides a suction nozzle assembly, comprising:

[0008] The mouthpiece has an inner wall and an outer wall, the inner side of which forms a mouthpiece channel, and a receiving cavity is defined between the inner wall and the outer wall. The mouthpiece channel is used to communicate with the atomization channel of the atomizing device. A carrier plate is located in the receiving cavity, or on the side of the receiving cavity opposite to the mouthpiece channel outlet in the extending direction of the mouthpiece channel. A metal sheet is connected to the carrier plate, and the metal sheet is used to electrically connect to the control module in the atomizing device. The metal sheet extends toward the receiving cavity and contacts one side of the outer wall. The metal sheet generates a capacitance change in response to the user's lips contacting the other side of the outer wall.

[0009] In an alternative embodiment, the metal sheet is in elastic contact with the outer sidewall.

[0010] In one alternative embodiment, the metal sheet has a cantilever end located within the accommodating cavity, the cantilever end elastically abutting against the inner sidewall, and the metal sheet has a contact surface that conforms to the outer sidewall.

[0011] In one alternative embodiment, in the extending direction of the suction channel, the distance between the outer sidewall and the inner sidewall gradually decreases from the inlet of the suction channel to the outlet of the suction channel; the cantilever end of the metal sheet contacts the outer sidewall.

[0012] In one alternative embodiment, the outer sidewall includes a first sidewall and a second sidewall arranged opposite to each other in a plane perpendicular to the extension direction of the suction channel, and there are two metal sheets, which respectively contact the first sidewall and the second sidewall.

[0013] In one optional embodiment, the outer side wall and / or the carrier plate are provided with a first notch, and the outer side wall and the carrier plate form a wire passage at the first notch, and the external wiring on the carrier plate for electrical connection with the control module passes through the wire passage.

[0014] According to a second aspect, one embodiment provides an atomizing device, including a housing and a mouthpiece assembly as described in any of the preceding claims, wherein the mouthpiece is connected to the housing, the atomizing channel is located inside the housing, and the mouthpiece channel communicates with the atomizing channel.

[0015] In one optional embodiment, the atomizing device further includes an atomizing chamber defining the atomizing channel, the receiving cavity being located between the mouthpiece and the atomizing chamber; in the extending direction of the mouthpiece channel, the atomizing chamber has a receiving groove with its opening facing the receiving cavity, and the carrier plate being located within the receiving groove.

[0016] In one optional embodiment, a limiting protrusion is provided on the side wall of the receiving groove, the limiting protrusion being able to abut against the carrier plate to prevent the carrier plate from dislodging from the opening of the receiving groove.

[0017] In one optional embodiment, the atomizing device includes a control module located on the side of the atomizing chamber opposite to the mouthpiece assembly in the direction of extension of the mouthpiece channel. The carrier plate is electrically connected to the control module via an external wiring connection, and a second notch is provided on the side wall of the receiving groove to avoid the external wiring connection.

[0018] According to the above embodiments of the mouthpiece assembly and atomizing device, the mouthpiece assembly includes a mouthpiece and a carrier plate. The mouthpiece has an inner sidewall and an outer sidewall. The inner sidewall forms a mouthpiece channel, and a receiving cavity is defined between the inner sidewall and the outer sidewall. The mouthpiece channel is used to communicate with the atomizing channel of the atomizing device. The carrier plate is located in the receiving cavity, or on the side of the receiving cavity opposite to the mouthpiece channel outlet in the extending direction of the mouthpiece channel. A metal sheet is connected to the carrier plate. The metal sheet is electrically connected to the control module in the atomizing device. The metal sheet extends toward the receiving cavity and contacts one side of the outer sidewall. The metal sheet generates a capacitance change in response to the user's lips contacting the other side of the outer sidewall. This capacitance change is transmitted to the control module, which can control the heating of the atomizing core. Thus, the atomizing device in the above embodiments can control whether the atomizing core works by detecting whether the user's lips contact the other side of the outer sidewall of the mouthpiece. Compared with the prior art structure that controls the atomizing core by detecting airflow changes, the structure in the above embodiments is not affected by air leakage in the atomizing device, which helps to improve the reliability of the atomizing core control by the atomizing device.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods.

[0025] This application provides a mouthpiece assembly that can be used in an atomizing device. The user's lips can wrap around the outer wall 21 of the mouthpiece assembly, and the aerosol in the atomizing channel 61 can be drawn out through the mouthpiece channel 25 of the mouthpiece assembly. The mouthpiece assembly can also cooperate with the control module 7 and the atomizing core 67 in the atomizing device. It can control whether the atomizing core 67 works by detecting whether the user's lips are in contact with the outer wall 21 of the mouthpiece, which can avoid the use of an airflow sensor and improve the reliability of the atomizing device's control over the atomizing core.

[0026] The suction nozzle assembly of this embodiment, as shown in Figures 1 to 4, includes a suction nozzle 2 and a carrier plate 3. The suction nozzle 2 has an integrally formed inner sidewall 20 and an outer sidewall 21. The suction nozzle 2 has a suction nozzle channel 25 and a receiving cavity 26. The inner sidewall 20 surrounds and forms the suction nozzle channel 25. The inner sidewall 20 can be sealed with the atomizing chamber 6 in the atomizing device so that the suction nozzle channel 25 communicates with the atomizing channel 61 in the atomizing chamber 6. The outer sidewall 21 is located outside the inner sidewall 20, and at least part of the outer sidewall 21 is located outside the inner sidewall 20. The accommodating cavity 26 is located between the outer side wall 21 and the inner side wall 20 and is not connected to the mouthpiece channel 25. The outer side wall 21 of the mouthpiece 2 has an inner surface facing the accommodating cavity 26 and an outer peripheral surface facing away from the inner surface and away from the accommodating cavity 26. When the atomizing device is in use, the user's lips can wrap around or adhere to the outer surface of the outer side wall 21 to fix the entire atomizing device and draw out the aerosol discharged from the outlet 252 of the mouthpiece channel 25.

[0027] In some embodiments, referring to Figure 4, the mouthpiece channel 25 has an inlet 251 and an outlet 252. The inner sidewall 20 at the end where the inlet 251 of the mouthpiece channel 25 is located is used to seal with the outlet of the atomizing chamber 6 in the atomizing device. The inlet 251 of the mouthpiece channel 25 can communicate with the atomizing channel 61 in the atomizing chamber 6. The end where the outlet 252 of the mouthpiece channel 25 is located can face outward from the atomizing device. The user's lips can wrap around the outer peripheral surface of the outer sidewall 21 at the end where the outlet 252 of the mouthpiece channel 25 is located to receive the aerosol discharged from the outlet 252 of the mouthpiece channel 25.

[0028] In some embodiments, the carrier plate 3 may be disposed in the accommodating cavity 26, and the carrier plate 3 may be interference-fitted with the cavity wall of the accommodating cavity 26 to achieve a fixed connection between the carrier plate 3 and the suction nozzle 2.

[0029] In some embodiments, please continue to refer to FIG4, the carrier plate 3 may also be disposed on the side of the accommodating cavity 26 away from the outlet 252 of the mouthpiece channel 25 in the extension direction of the mouthpiece channel 25. The carrier plate 3 may be clamped and fixed between the atomizing chamber 6 and the mouthpiece 2, or the carrier plate 3 may also be snapped and fixed on the mouthpiece 2 or the atomizing chamber 6.

[0030] In this embodiment, a metal sheet 5 is connected to the carrier plate 3. The metal sheet 5 is electrically connected to the control module 7 in the atomizing device. The carrier plate 3 can be a fiberglass carrier plate or a circuit board. In some embodiments, please refer to Figures 2 to 4. The carrier plate 3 is a fiberglass carrier plate. The carrier plate 3 is mainly used to support and carry the metal sheet 5. The carrier plate 3 is electrically connected to the control module 7 in the atomizing device. The control module 7 includes a circuit board assembly that controls the atomizing core 67 to start or stop heating. In other embodiments, the metal sheet 5 is electrically connected to the carrier plate 3. The carrier plate 3 includes a circuit board. While carrying the metal sheet 5, the carrier plate 3 forms part of the control module 7 in the atomizing device. The carrier plate 3 is also electrically connected to the atomizing core 67 in the atomizing device to control the operation of the atomizing core 67.

[0031] In some embodiments, the metal sheet 5 may be formed by processing copper sheet. The metal sheet 5 extends toward the receiving cavity 26 in the extension direction of the suction channel 25. Please refer to Figure 4. One end of the metal sheet 5 is connected to the carrier plate 3. The metal sheet 5 is not directly embedded or embedded in the outer wall 21. The metal sheet 5 has no direct connection with the outer wall 21. The metal sheet 5 is only located between the outer wall 21 and the inner wall 20 of the suction nozzle and is in contact with the inner surface of the outer wall 21.

[0032] In other embodiments, a slot may be provided on the inner surface of the outer wall 21. During installation, part of the metal sheet 5 is inserted into the slot. In the direction perpendicular to the inner surface of the outer wall 21, the depth of the slot is slightly greater than or equal to the thickness of the metal sheet 5. The metal sheet 5 is interference-fitted with the slot to ensure that the metal sheet 5 is in contact with the inner surface of the outer wall 21.

[0033] In the embodiments of the mouthpiece assembly of this application, when the user's lips are in contact with the outer peripheral surface of the outer wall 21, the user's lips and the metal sheet 5 are isolated by the outer wall 21. A capacitance change will occur between the user's lips and the metal sheet 5. An IC can be set on the carrier plate 3. The IC can initially 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 peripheral surface of the outer wall 21 of the mouthpiece. Then, the capacitance change signal is transmitted to the control module 7, which can control the atomizing core 67 in the atomizing device to start heating. When the user's lips are not in contact with the outer peripheral surface of the outer wall 21, the IC does not detect the capacitance change signal generated on the metal sheet 5, and the control module 7 controls the atomizing core 67 to stop heating.

[0034] In this embodiment of the application, the mouthpiece assembly cooperates with the control module 7 and the atomizing core 67 in the atomizing device. It can control whether the atomizing core 67 works by detecting whether the user's lips are in contact with the outer peripheral surface of the outer wall 21 of the mouthpiece. Compared with the current structure that controls the operation of the atomizing core 67 by detecting changes in airflow, the structure in this embodiment that detects whether the user's lips are in contact with the outer peripheral surface of the outer wall 21 of the mouthpiece is not affected by whether the atomizing device leaks air, which helps to improve the reliability of the atomizing device's control over the atomizing core 67. Furthermore, since the part of the metal sheet 5 that contacts the outer wall 21 of the mouthpiece 2 is located in the accommodating cavity 26, the accommodating cavity 26 is independent of the mouthpiece channel 25 through the sealing cooperation between the inner side wall 20 and the atomizing chamber 6. This reduces the probability that aerosol or atomizing liquid will enter the space where the carrier plate 3 is located and seep into the carrier plate 3 or adhere to the metal sheet 5, which helps to further improve the reliability of the atomizing device's control over the atomizing core 67.

[0035] In some embodiments, referring to FIG4, the metal sheet 5 has a connecting section 51 and a cantilever section 52 arranged in the extending direction of the suction channel 25. The connecting section 51 is connected to the carrier plate 3, and the cantilever section 52 is located in the accommodating cavity 26 and can contact the inner surface of the outer wall 21.

[0036] In some embodiments, a slot may be provided on the inner surface of the outer wall 21 of the nozzle 2, and the metal sheet 5 may be located in the slot. During installation, the cantilever section 52 of the metal sheet 5 is inserted from one end of the slot. The depth of the slot in the direction perpendicular to the inner surface of the outer wall 21 of the nozzle 2 is slightly greater than or equal to the thickness of the metal sheet 5, so that the metal sheet 5 can contact the inner surface of the outer wall 21 of the nozzle 2 after it is inserted into the slot.

[0037] In some embodiments, please continue to refer to FIG4, the metal sheet 5 can also be configured to elastically contact the inner surface of the outer wall 21 of the suction nozzle 2. The inner surface of the outer wall 21 of the suction nozzle 2 gradually approaches the inner wall 20 of the suction nozzle from the inlet 251 to the outlet 252 of the suction nozzle channel 25, so as to satisfy that the inner surface of the outer wall 21 of the suction nozzle 2 is a slope, arc or curved surface structure. The metal sheet 5 can be a bent arc-shaped sheet structure.

[0038] The cantilever section 52 of the metal sheet 5 has a cantilever end 521 that extends away from the connecting section 51 in the extending direction of the metal sheet 5. During the insertion of the metal sheet 5 into the receiving cavity 26, the inner surface of the outer wall 21 of the suction nozzle 2 can interfere with the cantilever end 521 of the metal sheet 5. As the metal sheet 5 gradually extends into the receiving cavity 26, the inner surface of the outer 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 toward the suction nozzle channel 25. After the metal sheet 5 and the suction nozzle 2 are assembled in place, the metal sheet 5 and the inner surface of the outer wall 21 of the suction nozzle 2 are in elastic contact. This improves the contact reliability between the metal sheet 5 and the inner surface of the outer wall 21 of the mouthpiece 2, reduces the probability of the gap between the metal sheet 5 and the outer wall 21 of the mouthpiece 2 increasing due to drops, external impacts, etc., and ensures the sensitivity of capacitance changes between the metal sheet 5 and the user's lips when the user's lips contact the outer peripheral surface of the outer wall 21 of the mouthpiece. This helps to improve the reliability of detecting whether the user's lips are in contact with the outer peripheral surface of the outer wall 21 of the mouthpiece, thereby improving the sensitivity of the atomizing device's control over the atomizing core 67 and improving the reliability of the atomizing device's control over the atomizing core 67.

[0039] In some embodiments, after the metal sheet 5 and the nozzle 2 are assembled in place, only the cantilever end 521 of the metal sheet 5 can be elastically contacted with the inner surface of the outer wall 21 of the 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 on the metal sheet 5 connected between the cantilever end 521 and the connecting section 51 can elastically contact the inner surface of the outer wall 21 of the nozzle 2.

[0040] In some embodiments, please continue to refer to FIG4. The cantilever section 52 of the metal sheet 5 has a contact surface that elastically fits the inner surface of the outer wall 21 of the nozzle 2. Under the extrusion action of the inner surface of the outer wall 21 of the nozzle 2, the metal sheet 5 elastically bends at the connection position between the cantilever section 52 and the connecting section 51, so that the side wall surface of the cantilever section 52 facing away from the nozzle channel 25 is pressed against the inner surface of the outer wall 21 of the nozzle 2. This can increase the contact area between the outer wall 21 of the nozzle 2 and the metal sheet 5, and improve the contact reliability between the metal sheet 5 and the outer wall 21 of the nozzle 2.

[0041] The cantilever end 521 of the cantilever section 52 on the metal sheet 5 also elastically abuts against the inner wall 20 of the mouthpiece 2. In this way, under the elastic abutment action of the inner wall 20 of the mouthpiece 2 against the cantilever end 521 of the metal sheet 5, the area of ​​elastic contact between the cantilever section 52 and the outer wall 21 of the mouthpiece 2 can be further increased, further reducing the probability of the gap between the metal sheet 5 and the outer wall 21 of the mouthpiece 2 increasing due to dropping, external force impact, etc., and further improving the reliability of detecting whether the user's lips are in contact with the outer wall 21 of the mouthpiece, and further improving the reliability of the atomizing device's control over the atomizing core 67.

[0042] In some embodiments, please continue to refer to FIG4. In the extension direction of the suction channel 25, the distance between the outer sidewall 21 and the inner sidewall 20 of the suction 2 gradually decreases from the inlet 251 to the outlet 252 of the suction channel 25. The outer sidewall 21 of the suction 2 gradually tilts towards the suction channel 25 in the direction from the inlet 251 to the outlet 252 of the suction channel 25, so that the outer sidewall 21 of the suction 2 forms an arc-shaped or inclined sidewall. As the metal sheet 5 extends into the accommodating cavity 26, the interference of the outer sidewall 21 of the suction 2 on the metal sheet 5 gradually increases, and the elastic pressure of the outer sidewall 21 of the suction 2 on the metal sheet 5 gradually increases, which can increase the bonding elasticity between the outer sidewall 21 of the suction 2 and the metal sheet 5, and improve the bonding reliability between the metal sheet 5 and the outer sidewall 21 of the suction 2.

[0043] The cantilever section 52 of the metal sheet 5 is attached to the outer wall 21 of the mouthpiece 2. The cantilever end 521 of the metal sheet 5 is in contact with both the inner wall 20 and the outer wall 21 of the mouthpiece 2, so that the inner wall 20 of the mouthpiece 2 acts as a stop for the metal sheet 5, preventing gaps from forming between the metal sheet 5 and the outer wall 21 of the mouthpiece 2 due to falling, external impact, etc., thereby further improving the control reliability of the atomizing device on the atomizing core 67.

[0044] Some users prefer to only touch one side of the outer wall 21 of the mouthpiece 2 with their lips during the intervals between using the atomizing device. In order to avoid the atomizing core 67 heating up during the intervals between using the atomizing device, in some embodiments, please refer to FIG4, the outer wall 21 of the mouthpiece assembly may include a first side wall 23 and a second side wall 24 arranged opposite to each other in a plane perpendicular to the extension direction of the mouthpiece channel 25. In addition, two metal plates 5 are provided, and the two metal plates 5 respectively contact the inner surface of the first side wall 23 and the inner surface of the second side wall 24.

[0045] Two carrier plates 3 can be configured, each corresponding to one of the two metal pieces 5. The metal pieces 5 are mounted on the corresponding carrier plates 3 and electrically connected to them. Alternatively, referring to Figures 2 and 4, both metal pieces 5 can be mounted on the same carrier plate 3 and electrically connected to it. The two metal pieces 5 are spaced apart in the plane extending vertically into the mouthpiece channel 25. When the first sidewall 23 and the second sidewall 24 contact the user's upper and lower lips respectively, capacitance changes are generated between the two metal pieces 5 and the user's upper and lower lips. Both capacitance change signals can be transmitted to the control module 7 of the atomizing device. The control module 7 can be configured to heat the atomizing core 67 only when both capacitance change signals are transmitted to it. That is, the atomizing core 67 in the atomizing device can only be heated when the user's upper and lower lips are simultaneously in contact with the outer surfaces of the first sidewall 23 and the second sidewall 24 of the outer sidewall 21 of the mouthpiece 2. This avoids accidental heating of the atomizing core and helps increase the reliability of the atomizing device's control over the atomizing core 67.

[0046] In other embodiments, it can also be specified that when using the atomizing device, the outer surface of only one side of the outer wall 21 of the mouthpiece 2 should not come into contact with the user's lips or other parts. In this way, there can be only one metal sheet 5, which can only contact the inner surface of the first side wall 23 or the inner surface of the second side wall 24. In this way, when the user's lips are wrapped around the outer surface of the first side wall 23 and the outer surface of the second side wall 24 of the mouthpiece 2, the atomizing core 67 can be heated by the control module 7, thereby improving the reliability of the atomizing device's control over the atomizing core 67.

[0047] In some embodiments, referring to Figures 2 to 4, the suction nozzle 2 can be configured as a thin-walled shell structure, with the accommodating cavity 26 arranged around the suction nozzle channel 25. The carrier plate 3 is provided with a through hole for the inner sidewall 20 of the suction nozzle 2 to pass through, so that the carrier plate 3 is also arranged around the suction nozzle channel 25, thus satisfying the requirement that the two metal sheets 5 can be connected to the same carrier plate 3.

[0048] In other embodiments, two accommodating cavities 26 may be provided. The two accommodating cavities 26 are arranged at intervals on both sides of the suction channel 25 in the arrangement direction of the first side wall 23 and the second side wall 24. Two accommodating cavities 26, two metal sheets 5 and two carrier plates 3 are provided, and one accommodating cavity 26 corresponds to one metal sheet 5 and one carrier plate 3.

[0049] In some embodiments, referring to FIG3, the carrier plate 3 is located on the side of the accommodating cavity 26 away from the outlet 252 of the suction channel 25 in the extension direction of the suction channel 25. The outer side wall 21 of the suction nozzle 2 is provided with a first notch 22 at one end in the extension direction of the suction channel 25 away from the outlet 252 of the suction channel 25. The outer side wall 21 of the suction nozzle 2 and the carrier plate 3 form a wire passage 4 at the first notch 22. The external wire 31 on the carrier plate 3 for electrical connection with the control module 7 can pass through the wire passage 4.

[0050] 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 first 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.

[0051] 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 2 with the mouthpiece channel 25 outlet 252 protrudes from the housing 1, and the other end of the mouthpiece 2 with the mouthpiece channel 25 inlet 251 is located inside the housing 1. The mouthpiece 2 and the housing 1 can be connected by a snap-fit, or the end of the mouthpiece 2 with the mouthpiece channel 25 inlet 2 can be 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.

[0052] 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.

[0053] The receiving cavity 26 and the carrier plate 3 in the mouthpiece assembly are both located between the mouthpiece 2 and the atomizing chamber 6 in the extending direction of the mouthpiece channel 25. In some embodiments, the carrier plate 3 is located between the receiving cavity 26 and the atomizing chamber 6 in the extending direction of the mouthpiece channel 25. The carrier plate 3 can be positioned on the mouthpiece 2, or it can also be positioned on the atomizing chamber 6 to fix the position of the carrier plate 3 in the atomizing device.

[0054] In some embodiments, referring to Figures 3 and 4, a receiving groove 64 is provided on one of the sealing members 63 of the atomizing chamber 6 in the extending direction of the mouthpiece channel 25. The opening of the receiving groove 64 faces the receiving cavity 26. The carrier plate 3 can be positioned and installed in the receiving groove 64. The carrier plate 3 can be interference-fitted with the side wall of the receiving groove 64 to fix the position of the carrier plate 3 in the atomizing device. In other embodiments, the carrier plate 3 can be positioned on the sealing member 63 of the atomizing chamber 6 by snap-fit ​​installation to fix the position of the carrier plate 3 in the atomizing device.

[0055] In some embodiments, in the structure where the carrier plate 3 is installed in the receiving groove 64 of the sealing member 63, a gap may be left between the carrier plate 3 and the side wall of the receiving groove 64. The sealing member 63 may be made of rubber material to improve the sealing performance between the sealing member 63 and the cylinder 62, as well as the sealing performance between the sealing member 63 and the inner side wall 20 of the suction nozzle 2. To prevent the carrier plate 3 from falling out of the receiving groove 64, please continue to refer to Figures 3 and 4. A limiting protrusion 65 may be provided on the side wall of the receiving groove 64 to limit the movement of the carrier plate 3. The positioning protrusion 65 is located at the opening of the receiving groove 64 in the groove opening direction. The limiting protrusion 65 is arranged to protrude into the receiving groove 64 in a plane perpendicular to the groove opening direction. The limiting protrusion 65 can abut against the carrier plate 3 in the receiving groove 64 in the groove opening direction to prevent the carrier plate 3 from coming out of the groove opening of the receiving groove 64. When installing the carrier plate 3, since the sealing member 63 is made of rubber material, the carrier plate 3 can be installed in the receiving groove 64 by elastically deforming the limiting protrusion 65.

[0056] In some embodiments, referring to FIG4, in the plane extending perpendicular to the nozzle channel 25, the outer side wall 21 of the nozzle 2 is located within the receiving groove 64, and the end of the outer side wall 21 of the nozzle 2 can abut against the carrier plate 3 to restrict the position of the carrier plate 3 within the receiving groove 64. In other embodiments, the end of the outer side wall 21 of the nozzle 2 can be spaced apart from the carrier plate 3 in the extending direction of the nozzle channel 25, and the position of the carrier plate 3 within the receiving groove 64 is restricted only by the limiting protrusion 65.

[0057] In other embodiments, the sealing member 63 may be made of plastic material, and the limiting protrusion 65 may not be easily deformed elastically. In order to facilitate the installation of the carrier plate 3 in the receiving groove 64, please refer to FIG2. A second notch 641 may be provided on the side wall of the receiving groove 64. The width of the second notch 641 is slightly larger than the size of the carrier plate 3, so that the carrier plate 3 can be inserted from the second notch 641 between the limiting protrusion 65 and the bottom wall of the receiving groove 64.

[0058] In some embodiments, referring to Figures 2 to 4, the atomizing device also includes a control module 7. The control module 7 is located on the side of the atomizing chamber 6 away from the mouthpiece assembly in the extension direction of the mouthpiece channel 25. The carrier plate 3 can be electrically connected to the control module 7 via an external wiring 31. The second notch 641 on the side wall of the receiving groove 64 can be used to avoid the external wiring 31, so as to reduce the bending angle of the external wiring 31.

[0059] The cylinder 62 of the atomizing chamber 6 in the atomizing device has an outer side on the side where the external wiring 31 exits. This outer side is spaced apart from the outer casing 1. The external wiring 31 can pass through the gap between the outer side and the outer casing 1 to facilitate the connection of the external wiring 31 to the control module 7. Furthermore, both sealing members 63 are provided with clearance grooves 66, which are used for the external wiring 31 to pass through in order to fix the position of the external wiring 31 in the outer casing 1.

[0060] In other embodiments, the control module 7 can also be disposed between the atomizing chamber 6 and the mouthpiece assembly in the extension direction of the mouthpiece channel 25. In this way, the sealing part 63 of the atomizing chamber 6 does not need to be provided with the clearance groove 66, and the external wiring 31 does not need to pass through the gap between the cylinder 62 and the outer shell 1. The control module 7 can be fixedly installed on the atomizing chamber 6, and the carrier plate 3 can be fixed on the control module 7. There is no need to set up an external wiring 31, and the electrical connection between the carrier plate 3 and the control module 7 can be realized. Alternatively, the carrier plate 3 can be fixed on the mouthpiece 2, and the control module 7 can be fixed on the atomizing chamber 6. The carrier plate 3 and the control module 7 are connected through an external wiring, which can shorten the size of the external wiring and facilitate the electrical connection between the carrier plate 3 and the control module 7.

[0061] In other embodiments, the carrier plate 3 forms part of the control module 7, such as the control module 7 including a circuit board assembly, the circuit board assembly including a circuit board and electronic components mounted on the circuit board, wherein the circuit board forms the carrier plate 3 for carrying the connecting metal sheet 5.
