[0032] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0033] Please see Figures 1 to 4 In some embodiments, an electronic atomizing device is provided, which includes a mouthpiece 1, a seal 2, an atomizing assembly, and a control unit 4.

[0034] The atomizing component, when energized, heats and atomizes the atomizing matrix to generate an aerosol. The nozzle 1 includes a nozzle body 11 and a venting section 12 connected together. The venting section 12 is used to transport and guide the aerosol generated at the atomizing component for user inhalation. For example, the venting section 12 is hollow in the middle, forming a gas channel. In some embodiments, the venting section 12 can be tubular. This application does not specifically limit the length of the venting section 12, as long as it seals with the first protrusion 21 and forms an air passage. Furthermore, this application does not specifically limit the connection method between the venting section 12 and the nozzle body 11; for example, it can be integrally molded by injection molding or a detachable connection. The sealing element 2 is located at the lower part of the venting section 12. The vertical direction can be referred to... Figure 2 and Figure 3 The U and D directions are defined, with U being the upward direction and D being the downward direction. A groove 20 is recessed on the surface of the seal 2 facing the nozzle 1. A first protrusion 21 is provided in the center of the groove 20, and the first protrusion 21 seals with the vent 12 to form an air passage. The seal 2, the vent 12, and the nozzle body 11 together define a receiving cavity. The atomizing assembly is located on the side of the seal 2 away from the nozzle 1. Specifically, refer to... Figure 2 and Figure 3 The direction is shown in the diagram, and the atomizing component is located at the lower part of the seal 2.

[0035] The control unit 4 includes a first circuit board 41 and a sensing metal plate 43 disposed within the receiving cavity. The sensing metal plate 43 is connected to the first circuit board 41 and is used to generate a sensing signal. The first circuit board 41 is installed within the slot 20 of the sealing member 2. The control unit 4 is used to control the opening and closing of the atomizing assembly according to the sensing signal. Specifically, as... Figure 3 and Figure 4 In the illustrated embodiment, the outer and inner surfaces of the mouthpiece body 11 are provided with arc surfaces of consistent curvature. A sensing metal plate 43 is disposed close to the mouthpiece body 11. The control unit 4 includes two sensing metal plates 43 spaced apart on the first circuit board 41. The two sensing metal plates 43 extend along the arc surface of the inner surface of the mouthpiece body 11, approaching or adhering to the inner surface of the mouthpiece body 11. When the user's lips approach the mouthpiece body 11, the sensing metal plate 43 generates a sensing signal. For example, in one embodiment, the sensing signal is generated when the capacitance of the sensing metal plate 43 changes. The first circuit board 41 receives the sensing signal and controls the opening and closing of the atomizing assembly according to the sensing signal.

[0036] Of course, the first protrusion 21 is not limited to being located in the middle of the groove 20. This application does not exclude the possibility that the first protrusion 21 is located on one side of the seal 2. For example, the first protrusion 21 can be eccentrically located relative to the seal 2, that is, the centroid of the seal 2 and the centroid of the first protrusion 21 are not on the same straight line extending in the vertical direction. In this embodiment, one side of the seal 2 has more free space, and the sensing metal plate 43 can be located on the free side of the seal 2, thereby allowing for a larger sensing metal plate 43, improving sensitivity, and facilitating installation.

[0037] Alternatively, in some other embodiments, such as Figure 2 and Figure 5 As shown, the control unit 4 also includes a second circuit board 42, which is disposed on one side of the seal 2. The first circuit board 41 and the second circuit board 42 are connected, and the second circuit board 42 is used to control the opening and closing of the atomizing component according to the sensing signal. That is, the circuit board used to control the opening and closing of the atomizing component according to the sensing signal can be either the first circuit board 41 or the second circuit board 42. In other words, only one first circuit board 41 can be set as the main control board; or, both the first circuit board 41 and the second circuit board 42 can be set simultaneously, with the second circuit board 42 serving as the main control board. The first circuit board 41 sends the sensing signal it receives to the second circuit board 42, and the second circuit board 42 controls the opening and closing of the atomizing component according to the sensing signal.

[0038] In summary, since a sensing metal plate 43 is provided in the receiving cavity formed by the mouthpiece 1 and the sealing member 2, when the user's lips touch the mouthpiece 1, the sensing metal plate 43 generates a sensing signal. The control unit 4 is used to control the opening and closing of the atomizing component according to the sensing signal, so as to achieve the purpose of touch control of the atomizing component switch. This is different from the traditional airflow sensor trigger start-up, and there will be no problem of air leakage leading to poor sensor sensitivity. Since the first circuit board 41 and the sensing metal plate 43 are both located in the receiving cavity, the condensate inside the ventilation part 12 will not come into contact with the first circuit board 41 and the sensing metal plate 43, thus avoiding the problem of condensate seeping into the sensor.

[0039] like Figure 6 and Figure 7As shown, in some embodiments, the first protrusion 21 of the seal 2 has a first central through hole 210. The end of the vent 12 away from the nozzle body 11 is inserted into the first central through hole 210. This first central through hole 210 is also used to deliver aerosol. The aerosol generated at the atomizing assembly is guided to the vent 12 via the first central through hole 210. The vent 12 and the first central through hole 210 are press-fitted; for example, in some embodiments, the outer periphery of the vent 12 is embedded in the inner periphery of the first central through hole 210, or the inner periphery of the vent 12 receives the embedding of the outer periphery of the first protrusion 21. This seals the gap between the vent 12 and the first central through hole 210, preventing aerosol in the airway formed by the two from overflowing from the gap into the outer side of the airway, i.e., into the receiving cavity, ensuring the sealing of the receiving cavity where the first circuit board 41 and the sensing metal sheet 43 are located, thereby preventing electrical components from being contaminated by liquid at the nozzle 1 and causing failure.

[0040] Continue as Figure 6 and Figure 7 As shown, in some embodiments, the surface of the seal 2 facing the nozzle 1 includes a first surface 251 and a second surface 252. The first surface 251 is the bottom surface of the groove 20, and the second surface 252 is located on the periphery of the groove 20 and is higher than the groove 20. The second surface 252 is provided with a plurality of second protrusions 22. Specifically, the middle region of the surface of the seal 2 facing the nozzle 1 is recessed to form a groove 20 for mounting the first circuit board 41, and the second protrusions 22 are provided on the non-recessed second surface 252 on the periphery of the middle region. The circumferential side of the nozzle body 11 and the second protrusions 22 are sealed together. Specifically, as shown... Figure 6 and Figure 7 In the illustrated embodiment, the surface of the sealing member 2 facing the nozzle 1 is provided with four second protrusions 22. The four second protrusions 22 are arranged diagonally, together forming a slot higher than the groove 20. The circumferential side of the nozzle body 11 and the slot are interference-fitted. That is, the circumferential side of the nozzle body 11 is in close contact with each of the second protrusions 22 to achieve a seal between the nozzle body 11 and the second protrusions 22. Thus, the sealing member 2 and the nozzle body 11 achieve a sealing fit through the second protrusions 22, ensuring the sealing of the receiving cavity where the first circuit board 41 and the sensing metal sheet 43 are located. When the first circuit board 41 is installed into the groove 20, the nozzle body 11 is just above the first circuit board 41. Therefore, the nozzle body 11 can also limit the vertical movement of the first circuit board 41. For example, the end face of the nozzle body 11 facing the first circuit board 41 can be in close contact with the first circuit board 41.

[0041] like Figure 4 and Figure 5As shown, in some embodiments, the first protrusion 21 can also be used to limit the first circuit board 41. For example, the first circuit board 41 has a through hole 411 in the middle, which is adapted to the first protrusion 21. When the first circuit board 41 is installed in the slot 20, the first protrusion 21 can also limit the first circuit board 41.

[0042] Furthermore, such as Figure 6 As shown, in some embodiments, the height of the first protrusion 21 may be greater than the height of the second surface 252. Specifically, the height of the first protrusion 21 relative to the first surface 251 (i.e., the bottom surface of the slot 20) is greater than the height of the second surface 252 relative to the first surface 251. Therefore, the first protrusion 21 has sufficient height, and the first protrusion 21 provides better positioning of the first circuit board 41. Figures 2 to 5 As shown, in some embodiments, the electronic atomizing device further includes a housing 5, which has a cavity. A seal 2 is disposed within this cavity, and the outer peripheral surface of the seal 2 is in sealing engagement with the inner wall surface of the housing 5. For example, the seal 2 and the cavity of the housing 5 may be an interference fit, with the outer peripheral surface of the seal 2 in close contact with the inner wall surface of the housing 5. The sealing engagement between the seal 2 and the housing 5 further ensures the sealing of the receiving cavity containing the first circuit board 41 and the sensing metal sheet 43. One end of the housing 5 is an open end 51, and the circumferential side of the nozzle body 11 is connected to the open end 51 of the housing 5.

[0043] like Figure 4 As shown, in some embodiments, the opening end 51 of the housing 5 is provided with at least one first limiting portion 510, and the circumferential side of the suction nozzle body 11 is provided with at least one second limiting portion 110. One of the first limiting portion 510 and the second limiting portion 110 is a protrusion, and the other is a groove, and the two are fitted together. For example, in one embodiment, the first limiting portion 510 is a protrusion and the second limiting portion 110 is a groove; or, in another embodiment, the first limiting portion 510 is a groove and the second limiting portion 110 is a protrusion. The first limiting portion 510 and the second limiting portion 110 are fitted together to fasten the suction nozzle body 11 and the housing 5 together, which can further ensure the sealing of the receiving cavity where the first circuit board 41 and the sensing metal sheet 43 are located. Specifically, the opening end 51 of the housing 5 forms an opening communicating with the cavity, and at least one first limiting portion 510 is disposed at the edge of the opening.

[0044] Furthermore, in some embodiments, the seal 2 can be an elastic element. For example, the seal 2 can be made of materials with significant elastic deformation capabilities, such as silicone, rubber, or PVC. The elastic seal 2 provides a better sealing effect when it seals against the inner wall surfaces of the nozzle 1 and the housing 5.

[0045] like Figure 5and Figure 6 As shown, in some embodiments, the slot 20 is provided with at least one third limiting portion 201, and the first circuit board 41 is provided with at least one fourth limiting portion 410. One of the third limiting portion 201 and the fourth limiting portion 410 is a protrusion, and the other is a groove, and the two are fitted together. For example, in one embodiment, the third limiting portion 201 is a protrusion and the fourth limiting portion 410 is a groove; or, in another embodiment, the third limiting portion 201 is a groove and the fourth limiting portion 410 is a protrusion. The third limiting portion 201 and the fourth limiting portion 410 are fitted together to secure the first circuit board 41 in the slot 20.

[0046] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the electronic atomizing device further includes a battery cell 6, which is capable of storing and releasing electrical energy. The battery cell 6 is disposed on the side of the atomizing assembly away from the seal 2. The battery cell 6 is connected to the atomizing assembly and supplies power to the atomizing assembly.

[0047] like Figures 2 to 4 As shown, in some embodiments, the electronic atomizing device further includes a liquid-absorbing component 7, which is disposed on the side of the sealing member 2 facing away from the nozzle 1, and is used to absorb condensate at the ventilation section 12 and the first protrusion 21. Specifically, the liquid-absorbing component 7 can be used to absorb condensate inside the ventilation section 12 and inside the first central through hole 210. This prevents condensate accumulation at the ventilation section 12 and the first protrusion 21, thereby reducing the risk of condensate entering the receiving cavity; at the same time, it also prevents condensate from flowing downwards to the atomizing component, causing an aerosol with an unpleasant taste, or leaking to the battery cell 6, causing contamination and damage to the battery cell 6. Specifically, the liquid-absorbing component 7 can be made of fibrous material.

[0048] like Figure 7 As shown, in some embodiments, the surface of the seal 2 facing away from the nozzle 1 is recessed with a mounting groove 23, and the liquid suction member 7 is fitted into the mounting groove 23. The liquid suction member 7 and the mounting groove 23 may be an interference fit.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments, the wall surface of the first central through hole 210 near the liquid suction member 7 is formed with an inclined surface 24 facing the liquid suction member 7. The inclined surface 24 is used to guide the condensate inside the first central through hole 210 to the liquid suction member 7, thereby further preventing the accumulation of condensate at the venting part 12 and the first central through hole 210.

[0050] like Figures 2 to 4As shown, in some embodiments, the liquid-absorbing component 7 is provided with a second central through hole 70, which is connected to the first central through hole 210. The atomizing assembly is located on the side of the liquid-absorbing component 7 away from the sealing component 2. The atomizing assembly includes an air guide tube 31 and an atomizing core (not shown), which is disposed within the cavity enclosed by the air guide tube 31. The atomizing core is connected to the battery 6. When energized, the atomizing core can heat and atomize the atomizing matrix to generate an aerosol, which is output from the air guide tube 31. The control unit 4 is connected to the battery 6, and the control unit 4 controls the energization and de-energization of the atomizing core according to the sensing signal. The end of the air guide tube 31 near the liquid-absorbing component 7 is inserted into the second central through hole 70, and the cavity enclosed by the air guide tube 31 is connected to the first central through hole 210 and the ventilation section 12 sequentially from bottom to top. The aerosol generated at the atomizing assembly flows sequentially from bottom to top through the air guide tube 31, the first central through hole 210, and the ventilation section 12. When the end of the venting tube 31 near the liquid-absorbing member 7 does not completely pass through the second central through hole 70, the aerosol also flows through the second central through hole 70. In a preferred embodiment, the end of the venting tube 31 near the liquid-absorbing member 7 completely passes through the second central through hole 70. That is, the entire wall surface of the second central through hole 70 is in contact with the venting tube 31. Furthermore, the end of the venting tube 31 near the liquid-absorbing member 7 can also extend into the first central through hole 210. Since the end of the venting tube 31 near the liquid-absorbing member 7 is inserted into the second central through hole 70, leakage of aerosol from the end of the venting tube 31 can be prevented; and the liquid-absorbing member 7 can be prevented from absorbing the aerosol overflowing from the venting tube 31, thereby avoiding premature saturation of the liquid-absorbing member 7.
