Description

Technical Field

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

[0002] Heating atomization can disperse liquid into smaller particles, making liquid molecules more dispersed in space. It is widely used in medical, agricultural, home appliances, electronic consumer products and other industries. Heating atomization is easy to implement and can be used to atomize most liquids. Atomized particles have been widely used in recent years. As the core component of heating atomization, the heating body is particularly important for innovation.

[0003] At present, the most widely used heating body in the field of heating atomization is the columnar heating body, which is mainly divided into two types: one is a columnar heating body formed by a heating wire spiral, and the other is a tubular heating body with a grid-like heating sheet wound into a C shape. The two electrodes of the two types of heating bodies are respectively set at the opposite ends of the heating body, which brings the following problems: 1. The electrodes need to be led out to the same end through electrode pins at both ends. The lead wires take up space during design, causing the liquid-conducting material outside the heating body to avoid the position of the lead wires when wrapping and matching, making assembly difficult; 2. The C-shaped tubular heating body is not a full circle in the circumference, and the radial support force is insufficient, which is easy to deform and cause poor contact with the liquid-conducting material.

[0052] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0053] like Figure 1-4 As shown, the atomization unit 2 of the present invention includes a tubular heating component 100 and a liquid guide 200. The liquid guide 200 can be wrapped around the outer periphery of the tubular heating component 100 or matched with the inner peripheral surface of the tubular heating component 100 to guide the adsorbed atomized liquid to the tubular heating component 100 to heat and form smoke.

[0054] like Figure 1 , 2 As shown in FIG. 1 , in the first embodiment of the atomization unit 2 of the present invention, the liquid guide 200 is wrapped around the outer periphery of the tubular heating component 100. The atomized liquid 300 is adsorbed from the outer periphery of the liquid guide 200, and then directed to the tubular heating component 100, and is heated and atomized to form smoke. Since the tubular heating component 100 is tubular as a whole, its inner circle channel forms an atomization channel, and the smoke formed by heating and atomization is output outward along the atomization channel, as shown in FIG. Figure 2 Indicated by the arrow.

[0055] like Figure 3 , 4As shown, in the second embodiment of the atomization unit 2 of the present invention, the liquid guide 200 is matched with the inner circumferential surface of the tubular heating component 100. The inner ring of the liquid guide 200 can be used as a liquid storage tank for storing the atomized liquid 300. A gap is left between the periphery of the tubular heating component 100 and the fixing parts required for installation and fixing for air flow. The atomized liquid 300 is adsorbed from the inner ring of the liquid guide 200, and then guided to the tubular heating component 100, where it is heated and atomized to form smoke, which is output outward along the outer circumferential surface of the tubular heating component 100, as shown in FIG. Figure 4 Indicated by the arrow.

[0056] In the atomizing unit 2 of the present invention, the cross-sectional shape of the tubular heating component 100 may be circular, polygonal or other shapes.

[0057] refer to Figure 4 , 5 The tubular heating component 100 includes an annular connecting portion 10, at least two heating portions 20 connected to one end surface of the connecting portion 10 and arranged around the end surface, an electrode portion 30 connected to one end of the heating portion 20 away from the connecting portion 10, and an electrode pin 40 connected to the electrode portion 30. In the axial direction of the entire tubular heating component 100, the connecting portion 10 and the electrode portion 30 are respectively located at opposite ends thereof, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30.

[0058] The connecting portion 10 has two opposite annular end faces, the heating portion 20 is connected to one end face of the connecting portion 10, and is arranged around the end face, and at least two heating portions 20 are spaced apart (not connected). The electrode portion 30 is connected to one end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, corresponding to the positive and negative electrodes, and each electrode portion 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power source such as a battery.

[0059] Each heating part 20 has two opposite sides, each side is opposite to the corresponding side of another adjacent heating part 20 and leaves a gap 50. At least two heating parts 20 are connected in series through the connecting part 10, so as to be connected to an external power source in series, and can have a larger resistance value than other heating parts of the same volume.

[0060] In the entire tubular heating component 100, the connection part 10 connects at least two relatively independent heating parts 20 into one body, thereby improving the strength of the tubular structure of the heating component. At least two electrode parts 30 are located at the same end of the heating component, which is convenient for assembly in the atomization device and connection with the battery.

[0061] The heating part 20 is provided with a hollow structure, so that a heating structure such as a heating circuit 21 is formed on the heating part 20. The heating circuit is long and has a reduced area, and has a larger resistance than the connecting part 10 and the electrode part 30, so that more heat is generated after power is turned on. In addition, the heating amount can be adjusted by adjusting the width and spacing of the heating circuit 21.

[0062] Furthermore, the hollow structure may include a plurality of through grooves 201 and / or a plurality of notches 202 spaced apart along the length direction of the heating portion 20 ; the arrangement of the hollow structure enables the heating portion 20 to form at least one heating circuit 21 .

[0063] In the first embodiment of the tubular heating element 100, as shown in FIG. Figure 5 , 6 As shown, the tubular heating component 100 includes two symmetrically arranged heating parts 20; one end of each heating part 20 away from the connecting part 10 is connected to an electrode part 30. The hollow structure on each heating part 20 includes a plurality of through grooves 201 and a plurality of notches 202. Among them, the plurality of through grooves 201 are arranged at intervals along the length direction of the heating part 20; two notches 202 are arranged between each two adjacent through grooves 201, and the two notches 202 are spaced opposite to each other. The arrangement of the through grooves 201 and the notches 202 enables the heating part 20 to include a plurality of heating rings connected in sequence in the length direction thereof, and the spacing part 203 between the two opposite notches 202 forms a connecting structure connecting the heating rings.

[0064] The heating part 20 can be divided into two heating circuits 21 with the center line as the symmetry axis, that is, the two heating circuits 21 are connected and symmetrical; the two heating circuits 21 are connected in parallel. Figure 6 The circuitous bending shape shown can also be other forms such as a broken line shape or a glass shape.

[0065] Considering the overall strength of the heating component, the width L1 of the spacing portion 203 (between two opposite notches 202 ) located at the midline of the heating portion 20 is preferably ≥ 2 times the width L2 of the notch 202 .

[0066] In the tubular heating component 100, the wall thickness of the heating part is 0.03mm-0.5mm. Alternatively, the tubular part of the tubular heating component 100 (including the connecting part 10, the heating part 20 and the electrode part 30) is an integrated structure with an overall wall thickness of 0.03mm-0.5mm.

[0067] The tubular heating component 100 can be made of metal materials such as stainless steel alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, titanium and titanium alloy, nickel-based alloy, Hastelloy alloy, etc. through cutting (specifically wire cutting, laser cutting, electric spark, etc.) and other processing methods.

[0068] Alternatively, the tubular portion of the tubular heating component 100 (including the connecting portion 10, the heating portion 20 and the electrode portion 30) can use a tube as a substrate, and form the connecting portion 10, the heating portion 20 and the electrode portion 30 thereon by cutting or other processing methods, and process a hollow structure on the heating portion 20 to form a heating circuit 21. Alternatively, the tubular portion of the tubular heating component 100 (including the connecting portion 10, the heating portion 20 and the electrode portion 30) can use a metal sheet as a substrate, and form a flat-plate-shaped connecting portion 10, a flat-plate-shaped heating portion 20 and a flat-plate-shaped electrode portion 30 thereon by cutting or other processing methods, and process a hollow structure on the heating portion 20 to form a heating circuit 21, and finally curl the processed metal sheet into a tubular shape, and weld the two ends of the connecting portion 10 together.

[0069] In addition, according to the required diameter, the overall diameter of the heating component can be adjusted by increasing or decreasing the number of the heating parts 20 of the tubular heating component 100 or increasing or decreasing the width of the heating parts 20 .

[0070] In the second embodiment of the tubular heating component 100, as Figure 7 As shown, the hollow structure on the heating part 20 includes a plurality of gaps 202 arranged at intervals and staggered along the length direction of the heating part 20. The arrangement of the plurality of gaps 202 enables the heating part 20 to form a heating circuit 21.

[0071] The heating portion 20 has one heating circuit 21 formed thereon, which is advantageous in reducing the width thereof compared to the heating portion 20 having two or more heating circuits 21 , thereby forming a heating component with a smaller diameter.

[0072] like Figure 8 As shown, in the third embodiment of the tubular heating component 100, what is different from the first embodiment is that the hollow structure on each heating part 20 forms two connected and symmetrical heating areas on the heating part 20, and each heating area includes two connected and symmetrical heating circuits 21. Therefore, each heating part 20 has four heating circuits 21, and the four heating circuits 21 are connected in sequence in the width direction of the heating part 20. Compared with the tubular heating components 100 of the first and second embodiments, the arrangement of the heating part 20 of this embodiment is suitable for tubular heating components with larger diameter requirements.

[0073] It can be understood that for the tubular heating components 100 with the same diameter requirements, the heating portion 20 can also form one or more heating circuits 21 according to requirements such as the heat generation and atomization effect.

[0074] Combination Figure 5-8In the tubular heating components 100 of the first to third embodiments, the widths of the through grooves 201 and the notches 202 are uniformly set, that is, on the heating portion 20, the widths of the plurality of through grooves 201 are equal, the widths of the plurality of notches 202 are also equal, and the widths of the through grooves 201 and the notches 202 can also be set equal.

[0075] In the fourth embodiment of the tubular heating component 100, as shown in FIG. Fig. 9 As shown, different from the first to third embodiments, in the length direction of the heating portion 20 , the width of the through slot 201 and / or the notch 202 located in the middle of the heating circuit 21 is greater than the width of the through slot 201 and / or the notch 202 located at both ends of the heating circuit 21 .

[0076] Due to the principle of heat radiation, the temperature in the middle of the heating part 20 is higher than the temperature at both ends of the heating part 20. Therefore, by setting the width of the through groove 201 and / or the notch 202 in the middle of the heating circuit 21 to be larger than the width of the through groove 201 and / or the notch 202 at both ends of the heating circuit 21, the spacing in the middle of the heating circuit 21 is large, and the spacing at both ends is small, so that the overall heating value of the heating part 20 is more uniform.

[0077] In the fifth embodiment of the tubular heating element 100, Fig.10 As shown, the tubular heating component 100 includes an annular connecting portion 10 , at least two heating portions 20 , at least two electrode portions 30 , and electrode pins 40 connected to the electrode portions 30 .

[0078] In the axial direction of the entire heating component, the connecting portion 10 and the electrode portion 30 are respectively located at the opposite ends thereof, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30. The connecting portion 10 has two opposite annular end faces, and the heating portion 20 is connected to one end face of the connecting portion 10, and is arranged around the end face, and at least two heating portions 20 are spaced apart (not connected). The electrode portion 30 is connected to one end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, and the corresponding positive and negative electrodes are distributed. Each electrode portion 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power source such as a battery. At least two heating portions 20 are connected in series through the connecting portion 10, so that an external power source is connected in series, and a larger resistance value can be achieved compared to other heating components of the same volume.

[0079] The heating part 20 is provided with a hollow structure, so that a heating structure such as a heating circuit 21 is formed on the heating part 20. The heating circuit is long and has a reduced area, and has a larger resistance than the connecting part 10 and the electrode part 30, so that more heat is generated after power is turned on. In addition, the heating amount can be adjusted by adjusting the width and spacing of the heating circuit 21.

[0080] By setting the hollow structure, one or more heating circuits 21 can be formed on each heating portion 21, and the details can be referred to the first to third embodiments above. The width of the through groove and / or the notch on the heating portion 21 can be set uniformly or non-uniformly, and the details can be referred to the first to third embodiments above, or the fourth embodiment, and will not be repeated here.

[0081] Different from the first to fourth embodiments, in this embodiment, a plurality of spaced through holes 204 are provided on the heating circuit 21. The provision of the through holes 204 increases the surface area of ​​the heating circuit 21, has higher thermal efficiency, and can also enable the heating circuit 21 to dissipate heat faster.

[0082] like Fig.11 As shown, in the sixth embodiment of the tubular heating component 100 , the tubular heating component 100 includes an annular connecting portion 10 , at least two heating portions 20 , at least two electrode portions 30 , and electrode pins 40 connecting the electrode portions 30 .

[0083] In the axial direction of the entire heating component, the connecting portion 10 and the electrode portion 30 are respectively located at the opposite ends thereof, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30. The connecting portion 10 has two opposite annular end faces, and the heating portion 20 is connected to one end face of the connecting portion 10, and is arranged around the end face, and at least two heating portions 20 are spaced apart (not connected). The electrode portion 30 is connected to one end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, and the corresponding positive and negative electrodes are distributed. Each electrode portion 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power source such as a battery. At least two heating portions 20 are connected in series through the connecting portion 10, so that an external power source is connected in series, and a larger resistance value can be achieved compared to other heating components of the same volume.

[0084] The heating part 20 is provided with a hollow structure, so that a heating structure such as a heating circuit 21 is formed on the heating part 20. The heating circuit is long and has a reduced area, and has a larger resistance than the connecting part 10 and the electrode part 30, so that more heat is generated after power is turned on. In addition, the heating amount can be adjusted by adjusting the width and spacing of the heating circuit 21.

[0085] The specific arrangement of the hollow structure on the heating portion 20 and the heating circuit 21 etc. may refer to the first to fourth embodiments mentioned above, and will not be described in detail here.

[0086] In this embodiment, at least one hollow portion 301 is provided on the electrode portion 30. The hollow portion 301 may be a through hole structure in a polygonal, circular, elliptical, etc. The hollow portion 301 is preferably provided at the end of the electrode portion 30 close to the heating portion 20.

[0087] Considering that the heat of the heating part 20 will be conducted to the electrode part 30, causing the temperature of the installation position of the electrode part 30 to be higher, therefore, by providing a hollow part 301 in the electrode part 30 to reduce its heat conduction area, a good heat insulation effect can be achieved, so that the temperature difference between the electrode part 30 and the heating part 20 is smaller.

[0088] like Fig.12 As shown, in the seventh embodiment of the tubular heating component 100, the tubular heating component 100 includes an annular connecting portion 10, at least two heating portions 20 connected to one end surface of the connecting portion 10 and arranged around the end surface, and an electrode portion 30 connected to one end of the heating portion 20 away from the connecting portion 10.

[0089] Each of the two opposite sides of the heating part 20 is opposite to the corresponding side of another adjacent heating part 20 with a gap; at least two heating parts 20 are connected in series through the connecting part 10. Each heating part 20 is connected to an electrode part 30, so the electrode parts 30 are spaced apart and distributed with corresponding positive and negative electrodes, and each electrode part 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power source such as a battery.

[0090] The heating part 20 is provided with a hollow structure, so that a heating structure such as a heating circuit 21 is formed on the heating part 20. The heating circuit is long and has a reduced area, and has a larger resistance than the connecting part 10 and the electrode part 30, so that more heat is generated after power is turned on. In addition, the heating amount can be adjusted by adjusting the width and spacing of the heating circuit 21.

[0091] In this embodiment, the hollow structure includes a plurality of through grooves 201 and a plurality of notches 202 arranged at intervals along the length direction of the heating portion 20, so that the heating portion 20 forms two connected and symmetrical heating circuits 21. Furthermore, through the arrangement of the diamond-shaped through grooves 201 and the triangular notches 202, each heating circuit 21 is formed in a zigzag or wavy shape, and the entire heating portion 20 is in a grid shape.

[0092] like Fig.13 As shown, in the eighth embodiment of the tubular heating component 100, what is different from the seventh embodiment is that the hollow structure includes a plurality of through slots 201 and a plurality of notches 202 arranged at intervals along the length direction of the heating portion 20, so that the heating portion 20 forms three heating circuits 21, two of which are spaced and symmetrical, and another heating circuit 21 is connected between the first two heating circuits 21. By setting the rhombus-shaped through slots 201 and the triangular notches 202, each heating circuit 21 is formed in a folded line or wave shape, and the entire heating portion 20 is in a grid shape.

[0093] In the seventh and eighth embodiments, the spacing of the heating circuits 21, the arrangement of the through holes, the arrangement of the hollow portions on the electrode portion 30, etc. can be arranged as required, and specific reference can be made to the relevant arrangements of the first to sixth embodiments.

[0094] In the tubular heating components 100 of the first to eighth embodiments described above, the electrode pins 40 are in a strip shape, forming electrode leads.

[0095] like Fig.14 As shown, in the ninth embodiment of the tubular heating component 100 , the tubular heating component 100 includes an annular connecting portion 10 , at least two heating portions 20 , at least two electrode portions 30 , and electrode pins 40 connecting the electrode portions 30 .

[0096] In the axial direction of the entire heating component, the connecting portion 10 and the electrode portion 30 are respectively located at the opposite ends thereof, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30. The connecting portion 10 has two opposite annular end faces, and the heating portion 20 is connected to one end face of the connecting portion 10, and is arranged around the end face, and at least two heating portions 20 are spaced apart (not connected). The electrode portion 30 is connected to one end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, and the corresponding positive and negative electrodes are distributed. Each electrode portion 30 is connected to an electrode pin 40 for connecting the positive and negative electrodes of a power source such as a battery. At least two heating portions 20 are connected in series through the connecting portion 10, so that an external power source is connected in series, and a larger resistance value can be achieved compared to other heating components of the same volume.

[0097] The heating part 20 is provided with a hollow structure, so that a heating structure such as a heating circuit 21 is formed on the heating part 20. The heating circuit is long and has a reduced area, and has a larger resistance than the connecting part 10 and the electrode part 30, so that more heat is generated after power is turned on. In addition, the heating amount can be adjusted by adjusting the width and spacing of the heating circuit 21.

[0098] According to the needs, in this embodiment, at least one hollow portion 301 may be provided on the electrode portion 30. By providing the hollow portion 301 on the electrode portion 30, its heat conduction area is reduced, which can play a good heat insulation role, so that the temperature difference between the electrode portion 30 and the heating portion 20 is smaller. The hollow portion 301 can be a through hole structure in a polygonal, circular, elliptical or other shape. The hollow portion 301 is preferably provided at the end of the electrode portion 30 close to the heating portion 20.

[0099] Different from the first to eighth embodiments described above, in this embodiment, the electrode pin 40 is an electrode sheet extending outward from one end of the electrode portion 30 away from the heating portion 20. The electrode sheet can be further bent relative to the electrode portion 30 to increase the connection area with a power source such as a battery, and can also form a support foot to play a role in fixed support.

[0100] Another example Figure 1 , 2 As shown, in the atomization unit 2 of the first embodiment of the present invention, the tubular heating component 100 can be the tubular heating component 100 of any one of the first to ninth embodiments described above, the liquid guiding member 200 is wrapped around the outer periphery of the connecting portion 10, the heating portion 20 and the electrode portion 30 of the tubular heating component 100, and the electrode pins 40 of the tubular heating component 100 extend out of the liquid guiding member 200 to be respectively connected to the positive and negative electrodes of the power supply.

[0101] Similarly, in the atomizing unit 2 of the second embodiment of the present invention, the tubular heating component 100 can be the tubular heating component 100 of any one of the first to ninth embodiments. Figure 3 , 5 As shown, further, in the atomization unit 2 of this embodiment, the liquid guide member 200 includes a liquid guide cylinder 210 and an annular step 220 protruding from the outer periphery of one end of the liquid guide cylinder 210. The liquid guide cylinder 210 is inserted into the inner circle of the tubular heating component 100, and the electrode portion 30 of the tubular heating component 100 abuts against the annular step 220 or is partially embedded in the annular step 220. The liquid guide cylinder 210 can abut against the inner circumferential surface of the tubular heating component 100 in the inner circle of the tubular heating component 100, or the outer circumferential surface of the liquid guide cylinder 210 is embedded in the inner circumferential surface of the tubular heating component 100.

[0102] In the atomization unit 2 of the present invention, the liquid guiding member 200 may be a flexible porous liquid guiding member, such as liquid guiding cotton, etc. The liquid guiding member 200 may also be a hard porous liquid guiding member, such as a porous ceramic liquid guiding member, etc.

[0103] When the liquid-conducting member 200 is a flexible porous liquid-conducting member, in order to prevent the tubular heating component 100 from bending and deforming when the liquid-conducting member 200 wraps the tubular heating component 100, a supporting component may be provided to support and position the tubular heating component 100.

[0104] like Fig.15 and Fig.16 As shown, the atomization unit 2 of the third embodiment of the present invention, compared with the atomization unit 2 of the first and second embodiments, further includes a supporting component 400 for supporting the tubular heating component 100 .

[0105] The support assembly 400 includes a support seat 410 and a support member 420. The support seat 410 is sleeved on the electrode portion 30 of the tubular heating assembly 100. The support member 420 is passed through the inner circle of the tubular heating assembly 100 and plugged into the support seat 410. The liquid guide member 200 is wrapped around the outer periphery of the tubular heating assembly 100 and abuts against the support seat 410.

[0106] The support seat 410 may include a seat body 411, on which a central through hole 412 is provided that penetrates two opposite surfaces thereof, and at least two through holes 413 that are spaced and surround the periphery of the central through hole 412. One end of the support member 420 is inserted into the central through hole 412, and each electrode portion 41 of the tubular heating component 100 is inserted into a corresponding through hole 413, and the electrode pin 40 of the tubular heating component 100 passes through the through hole 413 to expose the lower end of the seat body 411. The through hole 413 may be set to a structure in which the upper end is wide and the lower end is narrow, such as forming a structure in which the width gradually decreases from one end to the other end, so as to guide the electrode portion 41 to pass through the through hole 413.

[0107] The support seat 410 is preferably made of silicone, which can be compressed to achieve a tight fit, seal and insulation. The support member 420 is preferably made of an insulating hard material, such as ceramics, plastics, etc.

[0108] The main body of the support member 420 is columnar, positioned on the support seat 410 and arranged in the inner circle of the tubular heating component 100, so as to avoid the problem of easy deformation of the tubular heating component 100 due to the gap between the heating part 30. The height of the support member 420 in the inner circle of the tubular heating component 100 can reach the junction of the electrode part 30 and the heating part 20, or to the end of the heating part 20, so as not to affect the heating effect of the heating part 20.

[0109] In addition, in order to ensure air circulation, the side wall of the support member 420 may be hollow or mesh-shaped, or a through hole may be opened on the side wall.

[0110] In this embodiment, Fig.15 , 16 As shown, the support member 420 includes a cylinder 421 with one end open and the other end closed; it may also include a cylinder seat 423 connected to the outer periphery of the open end of the cylinder 421. The open end of the cylinder 421 is inserted into the central through hole 412 of the support seat 410 and is located on the inner side of the electrode part 30 of the tubular heating component 100, and the cylinder seat 423 is matched with the bottom surface of the support seat 410 to prevent the cylinder 421 from slipping out of the support seat 410. The closed end of the cylinder 421 faces the heating part 20 in the tubular heating component 100, and is located at the junction of the electrode part 30 and the heating part 20 or the inner side of the end of the heating part 20.

[0111] The side wall of the closed end of the cylinder 421 is provided with at least one vent 422, which connects the atomization channel of the tubular heating component 100 and the internal channel of the cylinder 421, and the atomization channel of the tubular heating component 100 is connected to the external air through the open end of the cylinder 421 to ensure the circulation of air flow. The arrangement of the vent 422 on the side wall of the closed end of the cylinder 421 improves the gas inlet into the tubular heating component 100, and effectively prevents the condensate formed by the condensation of the atomizing steam of the atomizing unit 2 during the atomization process from leaking from the vent 422. The condensate formed by the condensation of the atomizing steam during the atomization process can accumulate in the annular space between the support seat 410, the cylinder 421 and the electrode part 30, and then be adsorbed by the liquid guide 200 through the hollow portion 301 arranged on the electrode part 30 for reuse.

[0112] In addition, the arrangement of the vent 422 on the side wall of the closed end of the cylinder 421 also changes the direction of the incoming airflow and blows toward the inner surface of the heating part 20, which can take away the high-temperature atomized steam while the incoming air temperature is relatively low, which can allow the heating part 20 to dissipate heat and cool down more quickly, thus avoiding the problem of heat accumulation during continuous operation. Furthermore, the atomization unit 2 of this embodiment also includes a sleeve 500 that is sleeved on the outer periphery of the liquid guide member 200 and the support seat 420. The side wall of the sleeve 500 is provided with at least one liquid guide hole 510 that runs through the inner and outer wall surfaces thereof, and the liquid guide hole 510 connects the liquid guide member 200 with a liquid storage tank arranged externally to achieve liquid conduction.

[0113] At least one protruding seal 414 may be provided on the outer periphery of the support seat 420, which is tightly matched with the inner wall surface of the sleeve 500 to play a sealing role.

The liquid storage tank 130 located on the periphery of the air duct 120 is connected to the liquid guide member 200 of the atomizer unit 2 for liquid conduction, so that the atomized liquid stored in the liquid storage tank 130 is adsorbed by the liquid guide member 200 and then guided to the tubular heating assembly 100 of the atomizer unit 2, and heated and atomized to form smoke, which is then output through the atomization channel and the air outlet 110, and the direction of output is as shown in FIG. Fig.17 Indicated by the arrow.

[0118] The base 320 is provided with an inwardly concave mounting slot 321, and the atomizing unit 2 is plugged into the mounting slot 321. The air inlet 310 is provided on the bottom surface of the mounting slot 321 and penetrates the bottom surface.

[0119] The sealant seat 330 is sleeved on the base 320, and the structural shape is set corresponding to the upper part of the sleeved base 320, such as one side extending along the inner circumference of the installation slot 321 of the base 320, and the other side extending along the outer circumferential side of the base 320. The side of the sealant seat 330 located in the installation slot 321 is provided with at least one protruding first sealing rib 331, which is used to fit tightly with the outer surface of the atomization unit 2 to achieve a sealing effect.

[0121] Taking the atomization unit 2 of the third embodiment as an example, in the housing 1, one end of the air guide tube 120 facing the atomization unit 2 is plugged into the sleeve 500 of the atomization unit 2, and the internal channel of the air guide tube 120 is connected to the atomization channel of the inner circle of the tubular heating component 100 through the sleeve 500.

[0126] Specifically, the base 320 of the base 3 is provided with a slot for the electrode 6 to be inserted therein. After the atomizing unit 2 is inserted and positioned on the base 3, the electrode pin 40 of the tubular heating component 100 passes through the bottom surface of the mounting slot 321 of the base 320 and is exposed on the bottom surface of the base 320 or penetrates into the base 320, and is in electrical contact with the electrode 6 inserted on the base 320, thereby conducting electricity between the electrode part 30 and the electrode 6.
