Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] At present, electronic atomization devices have become a relatively mature smoking substitute on the market. They use batteries to power the atomization component in the atomizer, so that the atomization component heats the liquid matrix under electrical drive to produce aerosol for users to inhale.

[0003] In the existing atomizers, the liquid guide hole of the tubular element is either set at one end of the heating element or arranged radially opposite to the heating element. When the liquid guide hole is set on one side of the heating element, in order to ensure the heating efficiency of the heating element, the longitudinal height of the heating element is set large. When the liquid guide element transfers the liquid matrix, the liquid matrix is ​​converted into aerosol by the heating elements close to the liquid guide hole area before reaching the heating elements far away from the liquid guide hole area, which affects the amount of aerosol generated and also causes waste of the heating elements far away from the liquid guide hole area. When the liquid guide hole is arranged radially opposite to the heating element, the temperature generated when the heating element is heated will affect the liquid matrix in the liquid storage chamber.

[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0062] One embodiment of the present invention provides an electronic atomization device, which can be seen in Figure 1 As shown, it includes an atomizer 1 for storing a liquid matrix and atomizing it to generate an aerosol, and a power supply device 10 for supplying power to the atomizer 1 .

[0063] In an alternative implementation, such as Figure 1 to Figure 2 As shown, the power supply device 10 includes a sub-shell 101 arranged at one end along the length direction, and a first insulating member 102, a second insulating member 103, a third insulating member 104 and a battery cell 105 accommodated inside the sub-shell 101, and an air inlet 108 and a charging port 109 are provided at the bottom of the sub-shell 101.

[0064] The first isolating member 102 is configured such that a portion thereof extends in a longitudinal direction perpendicular to the power supply device 10 and another portion thereof extends in a transverse direction parallel to the power supply device 10. The second isolating member 103 is configured such that a cylindrical shape extends in the longitudinal direction of the power supply device 10. The third isolating member 104 is configured such that a disc shape extends in the transverse direction of the power supply device 10. A portion of the first isolating member 102 fixes the first conductive pin 35 connecting the first heating element 31 and the second heating element 32 to the positive terminal of the battery cell 105, and another portion of the first isolating member 102 fixes and guides the second conductive pin 36 connecting the first heating element 31 and the third conductive pin 37 connecting the second heating element 32 to the controller 106 to prevent the second conductive pin 36 and the third conductive pin 37 from coming out. The second isolating member 103 is located between the side of the battery cell 105 and the inner side of the auxiliary housing 101. The third isolating member 104 is located between the battery cell 105 and the atomizer 1. The third isolating member 104 cooperates with the second isolating member 103 to isolate the atomizer 1 from the battery cell 105.

[0065] The power supply device 10 further includes a controller 106 disposed between the battery cell 105 and the bottom of the auxiliary housing 101 , and a fixing seat 107 for fixing the controller 106 . The controller 106 is operable to guide current between the battery cell 105 and the first heating element 31 and the second heating element 32 .

[0066] During use, the power supply device 10 further includes a sensor for sensing the suction airflow generated from the air inlet when the atomizer 1 is inhaled, and then the controller 106 controls the battery cell 105 to supply power to the atomizer 1 according to the detection signal of the sensor.

[0067] Furthermore, the first isolating member 102 , the second isolating member 103 and the third isolating member 104 are preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 1 into the sub-shell 101 from flowing to the controller 106 , sensors and other components inside the first isolating member 102 and the second isolating member 103 .

[0068] Figures 3 to 5 The embodiment shows Figure 1 The schematic structural diagram of an embodiment of the atomizer 1 includes:

[0069] Main housing 2; according to Figures 3 to 5 As shown, the main shell 2 is roughly in the shape of a flat cylinder; the main shell 2 has a proximal end 22 and a distal end 23 opposite to each other along the length direction; wherein, according to the requirements of normal use, the proximal end 22 is configured as an end for the user to inhale aerosol, and an inhalation port 24 for the user to inhale is provided at the proximal end 22; and the distal end 23 is used as an end for combining with the power supply device 10, and the distal end 23 of the main shell 2 is an opening 25, on which a detachable end cover 8 is installed, and the opening 25 structure is used to install various necessary functional components into the inside of the main shell 2.

[0070] The end cover 8 is also provided with an air inlet 82 for allowing external air to enter the atomizer 1 during suction.

[0071] See also Figures 3 to 5 As shown, the main housing 2 is provided with a liquid storage chamber 21 for storing liquid matrix, and an atomizing assembly for sucking liquid matrix from the liquid storage chamber 21 and heating and atomizing the liquid matrix.

[0072] Further in Figures 3 to 5 In the specific implementation shown, the interior of the main shell 2 is provided with an air pipe 26 extending from the proximal end 22 toward the distal end 23, a tubular element 5 extending in the longitudinal direction and spaced apart from and connected to the air pipe 26, and a sealing rubber sleeve 27 extending in the longitudinal direction and sleeved on the air pipe 26, a part of the sealing rubber sleeve 27 is also sleeved on the tubular element 5, and a step on the inner side of the sealing rubber sleeve 27 abuts against one end of the tubular element 5 to provide a stop; after assembly, the air pipe 26, the tubular element 5 and the sealing rubber sleeve 27 jointly define an output channel for outputting aerosol.

[0073] In a specific implementation, the tubular element 5 is an independent component, preferably made of a thinner rigid material, such as ceramic or stainless steel, etc. The air pipe 26 is molded integrally with the main housing 2 by a moldable material. The sealing rubber sleeve 27 is an independent component, preferably made of a flexible material, such as silicone.

[0074] And after assembly, a liquid storage chamber 21 for storing liquid matrix is ​​defined by the outer surface of the air pipe 26 , the outer surface of the sealing rubber sleeve 27 , the outer surface of the tubular element 5 and the inner wall of the main shell 2 .

[0075] and in Figures 3 to 5 In the embodiment shown, the liquid storage chamber 21 defined in the main housing 2 is closed by the main housing 2 at the proximal end 22; and the end of the liquid storage chamber 21 toward the distal end 23 is open 25. Figures 3 to 5 As shown, the atomizer 1 also includes:

[0076] The flexible sealing seat 9 is used to seal the open end 25 of the liquid storage chamber 21 toward the distal end 23, and to provide a seal between the end cover 8 and the main housing 2 to prevent the liquid matrix from leaking out. Fig.13 As shown, the flexible sealing seat 9 comprises:

[0077] The main housing 2 and the peripheral side wall 91 have a spacing space between them, and the spacing space is open on the side facing the end cover 8. During assembly, the end cover 8 is inserted or extended into the spacing space to abut against the end cover 8 for assembly. After assembly, the end cover 8 partially surrounds or encloses the peripheral side wall 91 and is supported from the outside by the end cover 8 to provide a seal between the end cover 8 and the main housing 2.

[0078] The end cover 8 is also provided with an extension arm 81 extending in the longitudinal direction; the extension arm 81 is protruding relative to other parts of the end cover 8. The extension arm 81 is substantially in the shape of an elongated cylinder. The surface of the extension arm 81 is provided with an air groove extending in the axial direction.

[0079] Correspondingly, the sealing seat 9 is provided with a through hole 93 that penetrates or extends to the upper end surface; after assembly, the extension arm 81 is inserted into or extends into the through hole 93, and an air passage for external air to enter the liquid storage chamber 21 is defined between the air groove and the inner surface of the through hole 93. When the negative pressure in the liquid storage chamber 21 exceeds a threshold, the external air entering through the air inlet hole can enter the liquid storage chamber 21 through the air passage defined by the air groove to relieve the negative pressure in the liquid storage chamber 21.

[0080] In some further variations, the air groove is formed on the inner wall surface of the through hole 93 ; accordingly, an air passage is defined between the air groove on the inner wall surface of the through hole 93 and the extension arm 81 .

[0081] The end cover 8 is fixedly connected to the auxiliary housing 101 via a sealing ring 83 , thereby combining the atomizer 1 and the power supply device 10 together.

[0082] See also Figures 3 to 5As shown, the tubular element 5 contains and is equipped with an atomizing assembly, and is provided with a plurality of circumferentially spaced liquid guide holes 51 for the liquid storage chamber 21 to enter; thus, the atomizing assembly is fluidically connected with the liquid storage chamber 21 through the liquid guide holes 51 to receive the liquid matrix.

[0083] And see further Figures 3 to 5 As shown, the atomization assembly includes: a liquid guiding element 7 , a first heating element 31 and a second heating element 32 .

[0084] The liquid guiding element 7 extends along the axial direction of the first heating element 31 and the second heating element 32 and surrounds the first heating element 31 and the second heating element 32 , and is used for guiding the liquid matrix to the first heating element 31 and the second heating element 32 .

[0085] In an optional implementation, the liquid-conducting element 7 includes flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or includes porous materials with a microporous structure, such as porous ceramics; the first heating element 31 and the second heating element 32 can be combined on the liquid-conducting element 7 by printing, deposition, sintering or physical assembly, or wrapped around the liquid-conducting element 7.

[0086] The liquid guiding element 7 is arranged in a cylindrical shape in the tubular element 5 along the longitudinal extension of the tubular element 5, and receives the liquid matrix from the liquid storage chamber 21 through the liquid guiding hole 51; the first heating element 31 and the second heating element 32 are arranged in the liquid guiding element 7 and combined with the liquid guiding element 7, and are used to heat at least part of the liquid matrix stored in the liquid guiding element 7 to generate aerosol;

[0087] In practice, the outer surface of the liquid-conducting element 7 along the radial direction blocks or communicates with the liquid-conducting hole 51, and the outer surface of the liquid-conducting element 7 is configured as a liquid-absorbing surface to receive and absorb the liquid matrix in the liquid storage chamber 21 through the liquid-conducting hole 51. The inner surface of the liquid-conducting element 7 along the radial direction is configured as an atomizing surface, and the atomizing surface is combined / fitted / abutted against the first heating element 31 and the second heating element 32; and after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the first heating element 31 and the second heating element 32 to generate an aerosol and release it.

[0088] like Fig.11 As shown, the liquid guiding element 7 extends in the longitudinal direction of the atomizer 1 and includes a first liquid guiding portion 71 and a second liquid guiding portion 72 arranged in the longitudinal direction; the first liquid guiding portion 71 surrounds the first heating element 31 to conduct the liquid matrix in the liquid storage chamber 21 to the first heating element 31; the second liquid guiding portion 72 surrounds the second heating element 32 to conduct the liquid matrix in the liquid storage chamber 21 to the second heating element 32.

[0089] See also Figure 6As shown, in this embodiment, the first heating element 31 and the second heating element 32 are arranged in sequence from the proximal end 22 to the distal end 23 along the longitudinal direction of the nebulizer 1, for heating the liquid matrix to generate an aerosol; the first heating element 31 and the second heating element 32 are configured to be cylindrical extending along the longitudinal direction of the nebulizer 1; the first heating element 31 and the second heating element 32 are coaxially arranged with the liquid guiding element 7.

[0090] And further based on Figure 5 and Fig.11 As shown, at least a portion of the support 4 is positioned inside the first heating element 31 and the second heating element 32 , and at least a portion of the support 4 is configured to provide support to the first heating element 31 and the second heating element 32 from inside the first heating element 31 and the second heating element 32 at the same time.

[0091] Since the first heating element 31 and the second heating element 32 are arranged in sequence from the proximal end 22 to the distal end 23 along the longitudinal direction of the atomizer 1, and the first heating element 31 and the second heating element 32 are supported by the bracket 4 so that the positions of the first heating element 31 and the second heating element 32 are stable. Since the first heating element 31 and the second heating element 32 are provided, when the first heating element 31 and the second heating element 32 work at the same time, the efficiency of converting the liquid matrix into aerosol can be improved. At the same time, when the liquid matrix is ​​heated, since the first heating element 31 and the second heating element 32 are arranged from the proximal end 22 to the distal end 23, the incoming liquid matrix is ​​transferred toward the proximal end 22 and the distal end 23 respectively, so that the first heating element 31 and the second heating element 32 can be quickly supplied with liquid matrix for heating to generate aerosol.

[0092] Further based on Figure 6 and Figure 8 As shown, the first heating element 31 and the second heating element 32 are arranged at intervals along the longitudinal direction of the atomizer 1; and / or, the first heating element 31 and the second heating element 32 do not overlap in the longitudinal direction of the atomizer 1. The first heating element 31 and the second heating element 32 do not overlap in the longitudinal direction. If the first heating element 31 and the second heating element 32 overlap in the longitudinal direction, the first heating element 31 and the second heating element 32 will heat the same heating area when working at the same time, causing waste.

[0093] Further based on Figure 6 As shown, it also includes:

[0094] A first conductive pin 35, a second conductive pin 36 and a third conductive pin 37;

[0095] The first heating element 31 is electrically connected between the first conductive pin 35 and the second conductive pin 36 ; the second heating element 32 is electrically connected between the first conductive pin 35 and the third conductive pin 37 .

[0096] The first heating element 31 and the second heating element 32 are both defined by side openings extending in the circumferential direction. The first heating element 31 and the second heating element 32 are commonly connected to a first conductive pin 35 extending longitudinally on one side of the circumference, and are respectively connected to a second conductive pin 36 and a third conductive pin 37 extending longitudinally on the other side.

[0097] The first heating element 31 and the second heating element 32 each have an electrode portion 33 located at both sides of the side opening, and a mesh-shaped resistance heating portion 34 extending between the electrode portions 33 .

[0098] In this embodiment, the first heating element 31 and the second heating element 32 are formed by winding a mesh substrate; the wound first heating element 31 and the second heating element 32 are non-closed tubular in the circumferential direction, or cylindrical with side openings along the longitudinal direction. It should be noted that the heating element 3 is a resistance heating mesh, a resistance heating coil, etc.

[0099] Furthermore, in some embodiments, the electrode portions 33 of the first heating element 31 and the second heating element 32 located on the first side of the side opening are both connected to the first conductive pin 35; the electrode portions 33 of the first heating element 31 and the second heating element 32 located on the second side of the side opening are respectively connected to the second conductive pin 36 and the third conductive pin 37.

[0100] Since the first conductive pin 35, the second conductive pin 36 and the third conductive pin 37 need to be extended to the far end to be electrically connected to the controller 106 of the power supply device 10, the second conductive pin 36 connected to the first heating element 31 needs to pass through the longitudinal position of the second heating element 32, so as to avoid the second conductive pin 36 contacting the second heating element 32 and causing a short circuit. Figure 6 As shown, the circumferential extension length of the first heating element 31 is greater than the circumferential extension length of the second heating element 32 , so that the second conductive pin 36 is spaced from the second heating element 32 in the circumferential direction, thereby allowing the second conductive pin 36 to avoid the second heating element 32 .

[0101] Further as Figure 6 As shown, the first heating element 31 has a first end 314 proximal to the proximal end 22;

[0102] The first conductive pin 35 and / or the second conductive pin 36 includes an elongated portion 38 extending out of the first end 314 .

[0103] It should be noted that the extension portion 38 is flush with the upper end of the bracket 4 .

[0104] Further, the first heating element 31 and the second heating element 32 are connected in parallel to the battery cell 105 for supplying power to the first heating element 31 and the second heating element 32 .

[0105] The first heating element 31 and the second heating element 32 are connected to the battery core 105 in parallel, so that the first heating element 31 and the second heating element 32 can heat the liquid substrate at the same time.

[0106] It should be noted that the first heating element 31 and the second heating element 32 are not only electrically connected to the battery cell 105, but also electrically connected to the controller 106, and the operation of the first heating element 105 and the second heating element 106 is controlled by the controller 106. The first heating element 31 and the second heating element 32 can be electrically connected to the controller 106 separately, and the controller 106 can only heat the first heating element 31 or the second heating element 32 separately instead of heating them in parallel at the same time; and the resistance value or heating power of the first heating element 31 and the second heating element 32 can be controlled to be substantially the same or different.

[0107] And further based on Figures 7 and 8 As shown, the bracket 4 includes a first support portion 41, a second support portion 42 and a third support portion 43 spaced apart in the longitudinal direction, the first support portion 41 is close to the proximal end 22, and the third support portion 43 is close to the distal end 23;

[0108] The first heating element 31 extends from the first support portion 41 to the second support portion 42;

[0109] The second heating element 32 extends from the second support portion 42 to the third support portion 43 .

[0110] The first support portion 41 provides support to the first heating element 31 from the inner side near the proximal end 22 of the first heating element 31;

[0111] The second support portion 42 provides support for the first heating element 31 and the second heating element 32 from the inner side at a position near the distal end 23 of the first heating element 31 and a position near the proximal end 22 of the second heating element 32;

[0112] The third support portion 43 provides support to the second heating element 32 from the inner side near the distal end 23 of the second heating element 32 .

[0113] Further based on Figures 7 and 8As shown, the first heating element 31 includes a first end 314 and a second end 315 which are opposite to each other in the axial direction, the first end 314 is close to the proximal end 22, and the second end is close to the distal end 23. The second heating element 32 includes a third end 324 and a fourth end 325 which are opposite to each other in the axial direction, the third end 324 is close to the proximal end 22, and the fourth end 325 is close to the distal end 23.

[0114] The first support portion 41 is arranged to provide support to the first heating element 31 from the inside near the first end 314, the second support portion 42 is arranged to provide support to the first heating element 31 and the second heating element 32 from the inside near the second end 315 and the third end 324, and the third support portion 43 is arranged to provide support to the second heating element 32 from the inside near the fourth end 325.

[0115] Since the first heating element 31 and the second heating element 32 are provided, the efficiency of the aerosol generation of the atomizer 1 is improved. At the same time, since the second support portion 42 is radially opposite to the liquid guiding hole 51, when the first heating element 31 and the second heating element 32 heat the liquid matrix provided by the liquid guiding element 7, the liquid matrix entering the liquid guiding element 7 through the liquid guiding hole 51 is transferred toward the proximal end 22 and the distal end 23, respectively, and can be supplied to the first heating element 31 and the second heating element 32 to generate aerosol.

[0116] Furthermore, in some embodiments, the resistive heating portion 34 of the first heating element 31 includes:

[0117] The first heating part 311 is configured to generate Joule heat;

[0118] The first tooth portion 312 extends from the first heating portion 311 toward the first end 314 and terminates at the first end 314;

[0119] The second tooth portion 313 extends from the first heating portion 311 toward the second end 315 and terminates at the second end 315 .

[0120] The resistive heating portion 34 of the second heating element 32 comprises:

[0121] The second heat generating portion 321 is configured to generate Joule heat;

[0122] The third tooth portion 322 extends from the second heating portion 321 toward the third end 324 and terminates at the third end 324;

[0123] The fourth tooth portion 323 extends from the second heating portion 321 toward the fourth end 325 and terminates at the fourth end 325 .

[0124] Furthermore, if Figure 7 and Figure 8 As shown, the bracket 4 also includes:

[0125] The first window 49 is defined between the first supporting portion 41 and the second supporting portion 42 . The first heating portion 311 is arranged opposite to the first window 49 and avoids the first supporting portion 41 and the second supporting portion 42 .

[0126] And / or, the second window 410 is defined between the second supporting portion 42 and the third supporting portion 43 , and the second heating portion 321 is arranged opposite to the second window 410 and avoids the second supporting portion 42 and the third supporting portion 43 .

[0127] Therefore, the first support portion 41 is arranged to provide support for the first tooth portion 312, the second support portion 42 is arranged to provide support for the second tooth portion 313 and the third tooth portion 322, the third support portion 43 is arranged to provide support for the fourth tooth portion 323, and the first support portion 41, the second support portion 42 and the third support portion 43 all avoid the first heating portion 311 and the second heating portion 321.

[0128] After assembly, the first support portion 41, the second support portion 42 and the third support portion 43 avoid the first heating portion 311 and the second heating portion 321, which is beneficial for preventing the heat of the first heating element 31 and the second heating element 32 from being transferred to the bracket 4 in large quantities. At the same time, the first support portion 41, the second support portion 42 and the third support portion 43 avoid the first heating portion 311 and the second heating portion 321, so that the first heating portion 311 and the second heating portion 321 are exposed in the hollow of the bracket 4, so that the first heating portion 311 and the second heating portion 321 are exposed to the air flow channel.

[0129] The first heating portion 311 and the second heating portion 321 may be configured to be a mesh shape having meshes. The number of the first tooth portion 312 , the second tooth portion 313 , the third tooth portion 322 and the fourth tooth portion 323 is plural and discrete.

[0130] When power is supplied, the first heating portion 311 and the second heating portion 321 mainly generate Joule heat when direct current flows through them, and the direct current basically flows mainly through the first heating portion 311 and the second heating portion 321. The current flows less through the first tooth portion 312, the second tooth portion 313, the third tooth portion 322 and the fourth tooth portion 323, and the first tooth portion 312, the second tooth portion 313, the third tooth portion 322 and the fourth tooth portion 323 basically generate less Joule heat, so that the heating area of ​​the resistive heating portion 34 is mainly located in the first heating portion 311 and the second heating portion 321.

[0131] Further as Figure 5 , Fig.10 , Fig.11As shown, the liquid guiding hole 51 is arranged at the longitudinal middle position of the tube wall of the tubular element 5, and the liquid guiding hole 51 is radially opposite to the second supporting portion 42. Thus, the liquid matrix flowing out of the liquid guiding hole 51 can be transferred to the proximal end 22 and the distal end 23 along the liquid guiding element 7, respectively. Because it is arranged at the longitudinal middle position of the tubular element 5 and radially opposite to the second supporting portion 42, the liquid guiding element 7 transfers the liquid matrix to the first heating element 31 and the second heating element 32 at substantially the same speed, thereby accelerating the transfer of the liquid matrix.

[0132] In some embodiments, the bracket 4 further includes a connecting portion 44 , which extends along the longitudinal direction and sequentially connects the first supporting portion 41 , the second supporting portion 42 , and the third supporting portion 43 .

[0133] Furthermore, in some embodiments, the bracket 4 further includes a stopper 45 exposed outside the liquid-conducting element 7, the stopper 45 is connected to the third supporting portion 43, and the stopper 45 abuts against the second heating element 32 to provide a stop. An abutting portion 47 is also provided at the bottom of the stopper 45.

[0134] Specifically, the first support portion 41 , the second support portion 42 and the third support portion 43 are configured to be coaxially arranged in an annular shape. The connecting portion 44 is configured to be an elongated shape extending between the first support portion 41 , the second support portion 42 and the third support portion 43 .

[0135] In some implementations, the support 4 is made of an electrically insulating rigid material, such as ceramic, PEEK, polytetrafluoroethylene, surface insulating metal or alloy, etc.

[0136] The support and assembly process of the bracket 4 for the first heating element 31, the second heating element 32, the liquid-conducting element 7, and the tubular element 5 includes:

[0137] S10, the unwound / flatly unfolded first heating element 31 is wound on the first support portion 41 and the second support portion 42, and the unwound / flatly unfolded second heating element 32 is wound on the second support portion 42 and the third support portion 43, as shown in FIG. Figure 8 As shown; after winding, the first support portion 41 is arranged to provide support for the first tooth portion 312, the second support portion 42 is arranged to provide support for the second tooth portion 313 and the third tooth portion 322, and the third support portion 43 is arranged to provide support for the fourth tooth portion 323. And, after winding, the electrode portions 33 of the first heating element 31 and the second heating element 32 are against the connecting portion 44; and after winding, the connecting portion 44 is extended into the side opening between the electrode portions 33. And after assembly, the lower end of the second heating element 32 is against the stopper 45.

[0138] and according to Figure 7 and Figure 8 As shown, a lead groove 46 is provided on the inner surface or the outer surface of the bracket 4 , and the first conductive pin 35 , the second conductive pin 36 and the third conductive pin 37 are at least partially accommodated and retained in the lead groove 46 .

[0139] A lead groove 46 is provided on the surface of the first support portion 41, a lead groove 46 is provided on the surface of the third support portion 43, and a lead groove 46 is provided on the surface of the stop portion 45. The lead groove 46 extends along the axial direction of the bracket 4 and is close to the connecting portion 44. After assembly, the first conductive pin 35, the second conductive pin 36 and the third conductive pin 37 are retained in the lead groove 46 and extend outside the stop portion 45.

[0140] S20, further Fig. 9 The first heating element 31 and the second heating element 32 are wrapped or wound around or sleeved with a liquid-conducting element 7; Fig. 9 As shown; the liquid-conducting element 7 may be a closed cylindrical flexible fiber, or may be wound by a flexible fiber strip; the lower end portion of the liquid-conducting element 7 abuts against the stopper 45.

[0141] S30, further Fig.10 The liquid-conducting element 7 in the embodiment is covered with a tubular element 5, that is, Fig.10 The assembly state. And according to Fig.10 As shown, the lower end of the tubular element 5 surrounds and is sleeved on the stopper 45, and abuts against the abutment 47 to form support and stop. At the same time, the bracket 4 also has a positioning protrusion 48 extending from the abutment 47 toward the stopper 45, and a positioning notch 52 is provided at the lower end of the tubular element 5; during assembly, the positioning protrusion 48 and the positioning notch 52 cooperate to provide positioning during assembly. And after assembly, the positioning protrusion 48 and the positioning notch 52 cooperate to prevent the tubular element 5 from rotating or turning relative to the bracket 4.

[0142] Or in some other variations, the positioning notch 52 may be a positioning groove, or a positioning hole or the like that provides a structure for positioning and preventing rotation.

[0143] further, Fig.10 The tubular element 5, the atomizing assembly, the bracket 4, and the lead fastener are assembled to form a module, which is beneficial for the modular production and assembly of the atomizer 1. Fig.10 The assembly module is inserted into the bracket hole 94 of the sealing seat 9 and fixed. Fig.10 After the module is assembled with the sealing seat 9, the first conductive pin 35, the second conductive pin 36 and the third conductive pin 37 pass through the bracket hole 94 to the outside of the sealing seat 9, and are bent to contact or weld with the battery cell 105 to form electrical conduction.

[0144] And further based on Fig.10In the preferred embodiment shown, the liquid-conducting element 7 made of flexible fiber or sponge material is squeezed or compressed from the inside and outside by the tubular element 5, the first heating element 31 / the second heating element 32 / the bracket 4, respectively, so that the liquid-conducting element 7 is stably confined and maintained between the tubular element 5 and the first heating element 31 / the second heating element 32 / the bracket 4.

[0145] See also Fig.10 and Fig.11 As shown, after assembly, at least a portion of the lower end of the tubular element 5 is at least partially inserted into the bracket hole 94 along with the bracket 4 , and the liquid guide hole 51 of the tubular element 5 is arranged in the area of ​​the liquid storage cavity 21 close to the distal end 23 .

[0146] And in a preferred implementation, the air pipe 26 and the tubular element 5 are inserted into the sealing rubber sleeve 27 by riveting or tight fitting, so that they are tightly combined and sealed; this is beneficial for preventing the liquid matrix from leaking therebetween.

[0147] During the inhalation process after assembly, the air entering from the air inlet 82 of the end cap 8 enters the hollow of the bracket 4 through the bracket hole 94 of the sealing seat 9, and after passing through the bracket 4, carries the aerosol released by the atomization surface and is output from the tubular element 5 and the air pipe 26 to the inhalation port 24 to be inhaled. The airflow path or airflow channel during the inhalation process passes through the bracket 4. Of course, the airflow path or airflow channel also passes through the tubular, annular or wound cylindrical liquid guide element 7. And, the airflow path or airflow channel passes through the tubular, annular or wound first heating element 31 and the second heating element 32.

[0148] In some embodiments, the atomizer 1 further comprises:

[0149] The sealing element 6 at least partially extends from the air inlet 24 and penetrates into the interior of the bracket 4 via the air pipe 26 .

[0150] Another part of the sealing element 6 is exposed outside the main housing 2 , and the part covers the air inlet 24 , and the diameter of the part is larger than the diameter of the air inlet 24 .

[0151] By providing the sealing element 6, the air inlet 24 can be blocked, and the liquid matrix stored in the liquid storage chamber 21 will be absorbed by the liquid guide element 7 and cannot evaporate to the outside, thereby avoiding the deterioration of the liquid matrix caused by the liquid storage chamber 21 being in contact with the air for a long time.

[0152] When the user is in use, the portion of the sealing element 6 exposed outside the main shell 2 can be operated to remove the sealing element 6 from the trachea 26 and the bracket 4, and the inhalation port 24 is opened for the user to inhale the aerosol.

[0153] The above are only preferred embodiments of the present invention and do not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
