In other words, in the present embodiment, the central angle corresponding to the overall arc length of the third arc-shaped portion 211 of the first bracket 21 and the fourth arc-shaped portion 221 of the second bracket 22 is equal to 180 °, and the first receiving space 206 and the second receiving space 207 are separated by the fourth connecting plate 218 and the sixth connecting plate 228 abutting against each other. The second housing space 207 in the present embodiment can be used to house a cylindrical member such as the heat generating body assembly 30. The second receiving space 207 is formed by the third arc-shaped part 211 of the first holder 21 and the fourth arc-shaped part 221 of the second holder 22, which not only saves materials, but also the inner sides of the first and second arc-shaped ribs 216 and 226 can be embedded into the first groove 300 on the surface of the heat-generating body assembly 30 to strengthen the fastening of the heat-generating body assembly 30.

In this embodiment, the first bracket 21 is formed with a first insertion groove 230 extending along the second transverse direction R2. The second frame 22 is formed with a first connector 240 which is engaged with the first insertion groove 230. Specifically, the present embodiment employs, but is not limited to, the following structure to form the first insertion groove 230: the first bracket 21 further includes a pair of first insertion plates 231 which are opposite and spaced apart from each other, the first insertion plates 231 vertically extend inward in the second transverse direction R2 from the axial upper end of the first flat portion 212 of the first bracket 21, and the first insertion groove 230 is formed between the pair of first insertion plates 231. The first plug 240 has a rod shape that extends perpendicularly inward in the second lateral direction R2 from the axially upper end of the second straight portion 222 of the second holder 22.

During assembly, the first connector 240 is inserted into the first insertion groove 230, so that the first bracket 21 and the second bracket 22 can be connected, and relative displacement between the first bracket 21 and the second bracket 22 in the first transverse direction R1 can be effectively prevented. Preferably, the axial cross section of the first plug 240 gradually increases from the free end thereof to the second straight portion 222, so as to improve the tight fitting strength between the first plug 240 and the first insertion groove 230.

Preferably, the first bracket 21 further includes a first top plate 232 extending perpendicularly from an axial upper end thereof in the second transverse direction R2, the first top plate 232 being connected to axial top ends of the pair of first socket plates 231. In other words, the axial section of the first insertion groove 230 in this embodiment is in the shape of an inverted U. The first insertion groove 230 of this arrangement prevents the second holder 22 from being displaced axially upward relative to the first holder 21, or prevents the first holder 21 from being displaced axially downward relative to the second holder 22.

Preferably, the first bracket 21 is formed with a second insertion groove 233 extending along the second transverse direction R2. A second plug connector 241 matched with the second insertion groove 233 is formed on the second bracket 22. Specifically, the present embodiment forms the second insertion groove 233 using, but not limited to, the following structure: the first bracket 21 further includes a second insertion plate 234 extending vertically inward from the axially lower end of the first flat portion 212 in the second transverse direction R2, and the second insertion plate 234 has an axial cross section that is U-shaped with an upward opening to form the second insertion groove 233, that is, the axial cross section of the second insertion groove 233 in this embodiment is U-shaped. The second plug 241 has a rod shape and extends perpendicularly inward in the second transverse direction R2 from an axially lower end of the second straight portion 222 of the second holder 22.

When assembling, the second connector 241 is accommodated in the U-shaped second insertion groove 233. In this manner, not only the first bracket 21 and the second bracket 22 can be further prevented from being displaced relative to each other in the first lateral direction R1, but also the second bracket 22 can be prevented from being displaced axially downward relative to the first bracket 21, or the first bracket 21 can be prevented from being displaced axially upward relative to the second bracket 22. In combination with the aforementioned engagement between the U-shaped first insertion slot 230 and the first insertion piece 240, the first support 21 and the second support 22 are effectively prevented from being displaced relative to each other in the axial direction. In other words, the first bracket 21 and the second bracket 22 in the present embodiment can only be displaced relative to each other in the second transverse direction R2 for performing operations such as disassembling the bracket assembly 20.

Preferably, the second plug connector 241 is in an angle shape, an axial upper end of the second plug connector 241 forms a bending portion 242, and the bending portion 242 abuts against an axial top end of the U-shaped second plug board 234, so as to further improve the assembling stability of the second plug connector 241 and the second plug groove 233.

It is understood that in other embodiments, the relative displacement of the first and second supports 21 and 22 in the axial direction and the first transverse direction R1 can be limited without forming the second insertion groove 233 and the second insertion piece 241. For example, a connecting plate (not shown) connecting the pair of first socket plates 231 may be formed at the axially lower end of the first socket 230, and thus, the first bracket 21 and the second bracket 22 may be displaced only in the second lateral direction R2 relative to each other.

In this embodiment, the first bracket 21 further includes a first positioning plate 235 extending perpendicularly from the upper axial end of the first flat portion 212, and the first positioning plate 235 is located between the second receiving space 207 and the cylindrical cavity 208. The first positioning plate 235 has an inverted U-shape in axial cross-section, thereby forming an inverted U-shaped first positioning groove 236 extending in the second transverse direction R2. The U-shaped first positioning slot 236 is adapted to receive the PCB board 42 of the heating control assembly 40. In this embodiment, the axial bottom end of the first positioning plate 235 is connected to the axial top end of the first connecting plate 215 of the first bracket 21.

Preferably, a second positioning plate 243 is also vertically connected to the second straight portion 222 of the second bracket 22, and the second positioning plate 243 is aligned with the first positioning plate 235 along the second transverse direction R2. The second positioning plate 243 is also formed in an inverted U-shape in axial cross section, i.e., also has a second positioning groove 244 formed in an inverted U-shape. After the assembly of the bracket assembly 20 is completed, the PCB board 42 can be positioned more stably by the combined definition of the first positioning plate 235 on the first bracket 21 and the second positioning plate 243 on the second bracket 22.

Preferably, the axial lower end of the first flat portion 212 of the first bracket 21 is further formed with a first through groove 237 axially aligned with the first positioning groove 236. Specifically, the present embodiment employs, but is not limited to, the following structure to form the first through groove 237: the axially lower end of the first connection plate 215 protrudes in the second transverse direction R2 to form a first extension 238, and the first extension 238 and one side of the second socket plate 234 jointly define the first through groove 237. Correspondingly, the axially lower end of the second straight portion 222 of the second bracket 22 is also formed with a second through slot 245 axially aligned with the second positioning slot 244. Similarly, the lower axial end of the second connecting plate 225 also protrudes along the second transverse direction R2 to form a second extending portion 246, and the second extending portion 246 and one side of the second plug 241 form the second through slot 245. After the assembly of the bracket assembly 20 is completed, the end of the first extension 238 abuts against the end of the second extension 246, and the first through slot 237 and the second through slot 245 are aligned and jointly define a substantially square through slot, so as to further limit the axial lower end of the PCB 42 where the through slot is formed.

In this embodiment, the first bracket 21 further includes a transverse partition plate 250 perpendicularly connected to the axial upper end of the first arc-shaped portion 210, and the axial upper ends of the first and second straight portions 212 and 222 protrude from the transverse partition plate 250 to form an end cavity at the axial upper end of the cylindrical cavity 208 together with the transverse partition plate 250. In this embodiment, the first frame 21 further includes a longitudinal partition plate 251 vertically connected to the transverse partition plate 250, the longitudinal partition plate 251 divides the end cavity into an inner cavity 209A and an outer cavity 209B arranged in parallel along the first transverse direction R1, wherein the first top plate 232 covers an axial top end of the inner cavity 209A.

The end surface of the transverse partition plate 250 located in the internal cavity 209A may be used for mounting smaller components such as the vibration motor 43 of the heating control assembly 40. Preferably, the first housing 11 further includes a limiting block 252 vertically extending from the first flat portion 212 into the internal cavity 209A, and the limiting block 252 is located right above the transverse separation plate 250 to further limit the components mounted on the transverse separation plate 250. The first housing 11 may further include a restraint post 253 extending vertically from the first flat portion 212 into the interior cavity 209A. By the spacing relationship between the position-limiting posts 253 and the position-limiting blocks 252, the wiring in the heating control assembly 40, such as the wiring between the switch 44 and the PCB 42 of the heating control assembly 40, which will be described below, can be laid out more orderly and stably (see fig. 4).

The external cavity 209B is adapted to receive the switch 44 of the heating control assembly 40 and the key assembly 70, the switch 44 being electrically connected to the PCB board 42. Specifically, as shown in fig. 8 to 10, a boss 254 extending along the first transverse direction R1 is formed on the longitudinal separation plate 251, and the switch 44 is inserted on the boss 254. Preferably, the longitudinal separation plate 251 is recessed from the first transverse direction R1 to form a plurality of second grooves 255, so that the outer side of the longitudinal separation plate 251 facing the key assemblies 70 looks like a grid. Preferably, opposite sides 256 of the longitudinal separation plate 251 in the second transverse direction R2 respectively extend outwardly in parallel with the first transverse direction R1, so that the external cavity 209B is substantially U-shaped extending in the second transverse direction R2. Third locking holes 205 of the bracket assembly 20, which are engaged with the third locking hooks 700 of the key assembly 70, are formed on two opposite sides 256 of the longitudinal separation plate 251.

The annular sidewall 713 and the base 712 together define a recessed receiving groove 715 for receiving the light guide 73. The base 712 has a second through hole 716 formed therethrough in the first lateral direction R1. In this embodiment, the first surface 710 of the key 71 includes the surface of the base 712, the annular sidewall 713, and the rim 714 facing the key holder 72. The second surface 711 of the key 71 comprises the base 712, the annular side wall 713, the surface of the rim 714 facing the light guide 73.

The key holder 72 includes a substantially annular body portion 720, and the third hook 700 is substantially perpendicular to the body portion 720 and is used for being snap-connected to the holder assembly 20. The body portion 720 encloses to form a second window 721. The design of the second window 721 makes it possible to press the key 71 from the outside. The body portion 720 includes two annular end surfaces 722 arranged oppositely along the first transverse direction R1, and an inner side 723 and an outer side 724 connecting the two annular end surfaces 722. The first abutting ring 701 for abutting against the second housing 12 is formed by extending outward in a radial direction from an end face 722 of the main body 720, which is away from the third hook 700. The main body 720 is sleeved on the outer periphery of the annular side wall 713 of the key 71, and the inner side 723 of the main body 720 abuts against the outer surface of the annular side wall 713 of the key 71. Preferably, an end face 722 of the body portion 720 facing the third hook 700 abuts against an end face of the rim 714 of the key 71. Preferably, the thickness of the inner side 723 of the body portion 720 is substantially equal to the thickness of the annular side wall 713 of the key 71, so that an end face 722 of the key holder 72 facing away from the third catch 700 is substantially flush with the outer surface of the base 712 of the key 71 (see fig. 4).

In this embodiment, a pair of opposite sides of the main body 720, which are oppositely arranged along the second transverse direction R2, are respectively connected to a third hook 700. The third hook 700 extends perpendicularly or approximately perpendicularly from one end face 722 of the main body 720 along the first transverse direction R1, and is bent outward at the end. Preferably, the third hook 700 extends beyond the rim 714 of the key 71 to the positioning sleeve 74 (see fig. 4), and accordingly, the rim 714 of the key 71 has an avoiding groove 717 matched with the extension of the third hook 700 to ensure that the third hook 700 extends to the positioning sleeve 74. The avoidance groove 717 is recessed from a part of the side surface of the rim 714 of the key 71 in a direction parallel to the second transverse direction R2.

Preferably, the key 71 further includes a third protrusion 718 extending from an end surface of the rim 714 along an outer surface of the annular sidewall 713, and a third groove 725 is formed on the body portion 720 of the key holder 72 to be matched with the third protrusion 718. The third groove 725 is formed by recessing from an end face 722 of the main body portion 720, which abuts against the rim 714, along a direction parallel to the first transverse direction R1. Preferably, a set of opposite sides of the annular rim 714 in the axial direction are respectively formed with the third protrusion 718, and correspondingly, a set of opposite sides of the body portion 720 in the axial direction are also respectively formed with the third recess 725. The stability of the assembly of the key 71 and the key holder 72 can be improved by the cooperation of the third protrusion 718 and the third groove 725. To further improve the stability of the assembly of the key 71 and the key holder 72, the key holder 72 may further include a pressing piece 726 extending in the first transverse direction R1 from a side wall of an axial top end thereof, for example, and the pressing piece 726 presses against a surface (visible in fig. 4) of the corresponding third protrusion 718.

The light guide 73 includes a square first body portion 730. The first body portion 730 includes a first face 731 and a second face 732 oppositely arranged in the first transverse direction R1, and a side face 733 connecting the first face 731 and the second face 732.

The inner surface of the base 712 is formed with a fixing post 719 extending along the first transverse direction R1, and the first main body 730 is formed with a first insertion hole 734 engaged with the fixing post 719. In this embodiment, the first insertion hole 734 penetrates the first face 731 and the second face 732 of the first body portion 730.

The light guide 73 further includes a block-shaped visible portion 735 perpendicularly or substantially perpendicularly connected to the first face 731 of the first body portion 730, and a pressing portion 736 perpendicularly connected to the second face 732 of the first body portion 730. The visible portion 735 is received in the second through hole 716 of the key 71 to allow the visible portion 735 of the light guide 73 to be visible from the outside, and the remaining portion of the light guide 73 except the visible portion 735 may be hidden from view by the key 71. The pressing portion 736 abuts against the switch 44 of the heating control assembly 40. In this embodiment, the pressing portion 736 includes an axial plate extending along the axial direction and a transverse plate extending along the second transverse direction R2, the axial plate and the transverse plate preferably intersect at the center of the first main body portion 730, and the intersection portion can stably abut against the switch 44.

In this embodiment, the positioning sleeve 74 is substantially annular, and the switch 44 is at least partially accommodated in the central opening 740 of the positioning sleeve 74, so that the light guide member 73 can be abutted against the switch 44. In this embodiment, the positioning sleeve 74 is inserted into the longitudinal partition plate 251 of the bracket assembly 20. Specifically, the axially upper end of the positioning sleeve 74 is formed with a semi-annular skirt 741 extending in the first transverse direction R1. The semi-annular enclosure 741 includes two side walls 742 disposed opposite to each other in the second transverse direction R2, and a top wall 743 connecting axial top ends of the two side walls 743. Two side walls 742 of the surrounding plate 741 are respectively formed with a C/U-shaped opening 744 extending along the first transverse direction R1, and the C/U-shaped opening 744 is adapted to be fastened to one of the plates of the grid-shaped longitudinal partition plate 251, for example, the second top plate 251A of the longitudinal partition plate 251, in the thickness direction of the second top plate 251A.

Preferably, the axially lower end of the positioning sleeve 74 is further formed with a projection 745 extending in the first transverse direction R1, the projection 745 being adapted to be inserted into the second groove 255 of the grid-shaped longitudinal separation plate 251 to further improve the assembling stability of the positioning sleeve 74 and the longitudinal separation plate 251. An arc-shaped concave hole 746 matched with the convex column 254 of the longitudinal separation plate 251 for fixing the switch 44 can be formed by extending and recessing radially outwards inside the central opening 740 of the positioning sleeve 74, so that the assembling stability of the positioning sleeve 74 and the longitudinal separation plate 251 is further improved.

In this embodiment, a top plate 747 opposite to the surrounding plate 741 protrudes from an axial upper end of the positioning sleeve 74, an axial upper end surface of the rim 714 of the key 71 is adapted to abut against the top plate 747, and an axial lower end surface of the rim 714 of the key 71 and an axial lower end surface of the positioning sleeve 74 are spaced apart from each other at a certain distance. In this manner, not only is the key 71 positioned, but it is also ensured that the key 71 is movable relative to the positioning sleeve 74 to press against the switch 44 to activate or deactivate the switch 44.

During assembly, the positioning sleeve 74 can be inserted into the second top plate 251A of the longitudinal partition plate 251; then, the key support 72 is sleeved on the first surface 710 of the key 71, and the light guide member 73 is inserted into the accommodating groove 715 of the key 71; the third hook 700 is then snapped into the third snap hole 205 of the longitudinal partition plate 251, so that the assembled key holder 72, the key 71, and the light guide 73 are fixed to the holder assembly 20, and at this time, a part of the end surface of the key 71 abuts against the positioning sleeve 74.

Referring to fig. 12-15, the slide cover assembly 50 of the present embodiment is generally oval in shape, and includes a base 51 having a first surface 510 and a second surface 511 disposed opposite to each other in an axial direction, and a slide cover 52 slidably coupled to the first surface 510 of the base 51.

In this embodiment, the base 51 includes an elliptical base plate 53 and a sidewall 54 extending perpendicularly from the periphery of the base plate 53. The base plate 53 is formed with a circular insertion hole 530 penetrating therethrough in the axial direction. The insertion hole 530 is adapted to insert a roasting object, such as a cigarette C. The sliding cover 52 slides relative to the substrate 53 to open (when the electronic cigarette is used) or close (when the electronic cigarette is not used) the insertion hole 530, so as to ensure normal use of the electronic cigarette, and also play a role of dust prevention when the electronic cigarette is not used, wherein the sliding direction of the sliding cover 52 is parallel to the first transverse direction R1.

Specifically, the present embodiment employs, but is not limited to, the following structure to realize the relative sliding between the sliding cover 52 and the substrate 53: the slide cover 52 includes an oval-shaped slide plate 520 and a slide column 521 extending vertically from the axial bottom end of the slide plate 520; the base plate 53 further includes a preferably oval-shaped sliding groove 531 penetrating itself in the axial direction, the insertion hole 530 and the sliding groove 531 are arranged in order in the sliding direction of the slide cover 52, and the slide column 521 is slidably fitted in the sliding groove 531.

Preferably, the axial top end of the base plate 53 is further protrudingly formed with a stopper bar 532 extending in the sliding direction of the slide cover 52. The limiting bar 532 is located at one side of the sliding groove 531, and the length direction of the limiting bar 532 is parallel to the length direction of the sliding groove 531. Preferably, the length of the position limiting bar 532 is less than that of the sliding groove 531. The sliding cover 52 is formed with a stopper groove 522 engaged with the stopper bar 532. Preferably, two stopper bars 532 symmetrical with respect to the sliding groove 531 are formed at the axial top end of the base plate 53. Correspondingly, two limiting grooves 522 are formed on the sliding cover 52. The two limiting grooves 522 are symmetrical relative to the sliding column 521. Through the cooperation of the limiting strip 532 and the limiting groove 522, the sliding displacement of the sliding cover 52 relative to the base 51 can be limited, and the sliding process of the sliding cover 52 is more stable. Preferably, the sliding cover 52 is further formed with a plurality of ribs 523 at an axial top end thereof for allowing an operator to stably slide the sliding cover 52.

Preferably, the sliding cover assembly 50 in this embodiment further comprises a lens 55 arranged between the sliding cover 52 and the base plate 53 of the base 51. The lens 55 is elliptical and is embedded in the axial top end of the base plate 53. Specifically, the lens 55 is formed with a circular hole 550 penetrating therethrough in the axial direction and a third through hole 551 having a substantially square shape. The circular hole 550 is aligned with the insertion hole 530. The two position-limiting bars 532 on the base plate 53 are abutted against the hole walls of the third through holes 551. It is also preferable that the hole wall of the oval sliding groove 531 on the base plate 53 extends upward in the axial direction to form an oval convex strip 533. Two opposite hole walls of the third through hole 551 of the lens 55 along the first transverse direction R1 are further recessed to form arc-shaped hole walls 552, so as to abut against two opposite arc-shaped edges of the protruding strip 533 along the first transverse direction R1. The design of the lens 55 not only improves the wear resistance of the sliding cover 52, but also enhances the appreciation of the electronic cigarette.

Preferably, the slide cover assembly 50 further includes a slider 56 slidably coupled to the second surface 511 of the base 51. The sliding member 56 is preferably fixedly connected to the sliding cover 52 by a fixing member 57, so that the sliding member 56 can slide together with the sliding cover 52 relative to the base 51. The second surface 511 of the base 51 has a convex portion 582 and a concave portion 583, and the slider 56 has a snap portion 563 that can snap over the convex portion 582 to the concave portion 583.

Specifically, in the present embodiment, the base 51 further includes a blocking edge 58 vertically extending downward in the axial direction from the axial bottom end of the base plate 53. The blocking edge 58 is preferably substantially semi-annular and comprises two longitudinally opposite blocking strips 580 arranged in a radial direction and a preferably semi-circular connecting edge 581 connecting one end of the two blocking strips 580. Preferably, the sides of the two bars 580 opposite to each other are formed with the concave portion 583 and the convex portion 582. In this embodiment, each bar 580 includes two recesses 583 and a protrusion 582 disposed between the two recesses 583.

The slider 56 in this embodiment is preferably made of an elastic material, such as rubber, and is substantially annular, and includes an annular portion 560, and a fixing portion 561 connected to the annular portion 560. The axial top end of the sliding member 56 abuts against the axial bottom end of the base plate 53. The outer sides of two first edges 562 of the annular portion 560, which are arranged opposite each other in the radial direction (i.e. parallel to the second transverse direction R2), abut against the stop strip 580. The engagement portions 563 are formed on the outer sides of the first sides 562 to protrude radially outward. The engaging portion 563 extends into the concave portion 583 of the bar 580, and is preferably arc-shaped.

The fixing portion 561 is used for connecting with the fixing member 57, and extends from the inner side of a second side 564 of the ring portion 560 connecting the two first sides 562 along a direction parallel to the first transverse direction R1. Preferably, the fixing portion 561 is in the same plane as the ring portion 560.

In this embodiment, the fixing member 57 includes a fixing disk 570 having a circular shape, and a fixing pin 571 vertically extending from an axial top end of the fixing disk 570. The fixing pin 571 penetrates through the fixing portion 561 of the sliding member 56, and the fixing plate 570 abuts against an axial bottom end of the fixing portion 561. The sliding column 521 of the sliding cover 52 is a hollow cylinder with one open end. The fixing pin 571 penetrating through the fixing portion 561 is inserted into the sliding post 521 of the sliding cover 52. In this way, when the sliding cover 52 slides along the sliding groove 531, the sliding member 56 slides along with the sliding cover 52 by the cooperation of the sliding column 521 and the fixing pin 571, and the engaging portion 563 of the sliding member 56 can ride over the convex portion 582 of the corresponding bar 580 and engage with the concave portion 583 during the sliding process, thereby generating a sliding pause.

Preferably, when the engaging portion 563 of the slider 56 engages with the recessed portion 583 of the bar 580 remote from the insertion hole 530, the slide cover 52 is in a position to open the insertion hole 530; when the engaging portion 563 of the slider 56 engages with the concave portion 583 of the bar 580 adjacent to the insertion hole 530, the slide cover 52 is in a position to close the insertion hole 530. Thus, the sliding cover 52 can be slid to open or close the insertion hole 530, and the operation experience is good.

It will be appreciated that in other embodiments, other arrangements of snap-fit and recess/protrusion portions may be employed. For example, the engaging portion may be formed at the top end in the axial direction of the slider, and the convex portion and the concave portion may be formed at the bottom end in the axial direction of the base plate 53, so that the engaging portion projects into the concave portion in the axial direction. In this way, a feeling of pause can be generated also in the process of sliding the slide cover.

Preferably, the sliding cover assembly 50 in this embodiment further includes a clamping member 59 fixed to the axial bottom end of the base plate 53. Specifically, the clamping member 59 has a substantially semicircular shape, and is formed with a clamping hole 590 aligned with the insertion hole 530, and a plurality of fourth protrusions 591 extending radially inward from a hole wall of the clamping hole 590. In this embodiment, a plurality of fourth protrusions 591 are uniformly spaced along the wall of the clamping hole 590. Each of the fourth protrusions 591 has a substantially triangular shape with a tip toward the center of the clamping hole 590. The inserted cigarette C can be clamped by the design of the fourth protrusions 591. Preferably, said holding element 59 is made in one piece of a material with elastic properties, such as rubber, which is not only simple to manufacture, but also prevents the fourth protrusions 591 from damaging the cigarettes C.

In this embodiment, the clamping member 59 and the base plate 53 are connected by, but not limited to, the following structure: the base plate 53 has a plug portion 534 extending axially downward from an axial bottom end thereof, and the clamping member 59 has a second plug hole 592 to be plug-fitted with the plug portion 534 to fixedly connect the clamping member 59 and the base plate 53. The socket 534 may include a plurality of socket blocks 534A uniformly surrounding the insertion hole 530. The socket 534 may alternatively or additionally include, for example, a socket post 534B on the diametric side of the clamp 59. In either case, the second mating hole 592 on the clip member 59 is adjusted to mate with the mating portion 534.

During assembly, the lens 55 can be first assembled to the axial top end of the base 51, and then the sliding post 521 of the sliding cover 52 is inserted into the sliding groove 531. Next, the slider 56 is mounted to the axial bottom end of the base 51, and then the fixing member 57 is forcibly inserted through the fixing portion 561 of the slider 56 and is fitted to the sliding post 521 of the sliding cover 52. And finally, the clamping piece 59 is inserted into the axial bottom end of the base 51.

The second body 630 is axially inserted through the first through hole 613 and the second through hole 620. The outer diameter of the second main body 630 may be equal to or smaller than the diameters of the first and second through holes 613 and 620, that is, the second main body 630 may or may not abut against the hole walls of the first and second through holes 613 and 620.

Referring to fig. 24, there is shown a heating control method of the electric heating roasting apparatus, the heating control method comprising the steps of:

step S101 is to charge the battery 41 built in the electric heating and baking apparatus.

In this embodiment, the cigarette C is heated electrically, and specifically, the cigarette C to be heated can be placed in a smoke tube (such as the metal tube 31) with good heat conductivity, and heat is transferred to the smoke tube through the electrical heating, and the smoke tube then bakes the cigarette C to atomize the nicotine in the cigarette C for the user to smoke. Therefore, the battery 41 built in the electronic cigarette needs to be charged to ensure that the battery 41 has enough electric quantity to supply power to the heating part, the current electric quantity of the battery 41 can be indicated through a series of indicator lights in the charging process, for example, as the charging process, the current electric quantity gear is indicated by the display of a red light, a yellow light, a blue light and a green light respectively, or the red light is normally on in the charging process, and the green light is normally on after the charging process, and the built-in battery 41 can be selected from a lithium battery.

Step S102, responding to the operation that the user presses the start switch 44 for a long time, controlling the battery 41 to supply power to each heating part one by one, so that each heating part heats the corresponding cigarette C part, and when each heating part is heated to a preset temperature value, a smoking prompt is performed.

Specifically, an activation switch 44 may be provided on the electronic cigarette, and a predefined long press of the activation switch 44 indicates that heating is required, for example, a long press of the activation switch for 2 seconds. Then control battery 41 supplies power to each heating part according to the preset heating sequence, each heating part is electrified to generate heat and simultaneously transmits the heat to the tobacco pipe, and the heating temperature of each heating part to the tobacco pipe is detected in real time, when the preset temperature value is heated, the user is prompted to start smoking, and after the user finishes smoking the corresponding part of a cigarette C, control battery 41 supplies power to the next heating part.

The mode of segmentation heating can make the electric quantity in the battery 41 concentrate the power supply to certain heating part, and the cigarette C part that corresponds can be toasted sooner to make the nicotine composition in this cigarette C part atomize sooner, shorten the time that the user waited for the suction, promoted user experience.

And step S103, when the smoking duration is detected to exceed the preset time limit, prompting the smoking quitting state and stopping heating the heating part.

Considering that long-time smoking is harmful to the body, a certain time limit is set in the embodiment, for example, an upper smoking limit of 305 seconds can be set, the smoking duration of the user is detected in real time, and when the smoking duration exceeds the time limit, the smoking state is prompted to be exited, and power supply to the heating part which is currently working is stopped.

The preset time limit may be the sum of the smoking time of each part of the cigarette C by the user, for example, when the first section of the cigarette C is baked to the preset temperature, the user is prompted to smoke and start timing, and the timing is suspended after the preset time T1 is smoked by the user. And when the second section of cigarette C is baked to the preset temperature, prompting the user that smoking can be performed, continuously accumulating and timing on the basis of T1, and so on until the timing duration exceeds the preset time limit, indicating that the smoking is over time.

Even if the user presses the start switch 44 again, the response is not detected in a sleep time after the heating is stopped due to the timeout, and the response can not be resumed until the sleep time elapses, so that the smoking behavior of the user can be controlled.

Fig. 25 shows a specific implementation manner of the step S102, which includes:

step S1021, a driving signal is generated to control the connection of the circuit between the battery 41 and the current heating portion, so that the current heating portion heats the corresponding cigarette C portion, and the motor 43 is controlled to vibrate to prompt the current heating portion to start working.

In this embodiment, the on-off of the circuit between the built-in battery 41 of the electronic cigarette and each heating part is controlled by a driving signal, specifically, an MOS switch tube or the like may be provided on the circuit, the on-off of the MOS switch tube is controlled by a PWM driving signal to supply power to the heating part to heat the heating part, and the motor 43 vibrates as a prompt when the heating part is supplied with power every time.

Step S1022, detecting the heating temperature of the current heating part in real time, and adjusting the power of the driving signal according to the detected heating temperature.

For each heating part, the driving signal can be controlled to be high power when the heating part starts to heat, and the power of the driving signal can be reduced along with the increasing approach of the preset temperature so as to prevent the nicotine atomization speed from being too high due to the overhigh baking temperature.

In step S1023, when the currently heated portion is heated to a preset temperature value, the motor 43 is controlled to vibrate to indicate that it is pumpable.

In this embodiment, the vibration patterns of the motor 43 that prompt the start of heating and that prompt smoking may be set differently for user differentiation, e.g., one may be set to a continuous vibration and the other may be set to a pulsed vibration.

And step S1024, after the cigarette C part corresponding to the current heating part is sucked for a preset time, controlling to heat the next heating part.

It is understood that in other embodiments, other numbers of heating portions may be employed, such as three, four, etc.
