[0032] Example:

[0033] See also Figures 1 to 7The embodiment of the present invention provides a heating-not-burning device, comprising a housing 1, an extraction assembly 2, a heating assembly 3 and a battery rod assembly 4. The top of the housing 1 is provided with an insertion cavity 111 for inserting a cigarette 7; the extraction assembly 2 comprises a driving assembly 21 installed in the housing 1 and a sleeve 22 arranged in the insertion cavity 111 and connected to the driving assembly 21, the sleeve 22 is closed at the bottom and opened at the top, the driving assembly 21 is used to drive the sleeve 22 to move axially along the length direction of the insertion cavity 111, and the sleeve 22 is connected to the insertion cavity 111; the heating assembly 3 comprises a heating element 31 fixed in the housing 1, the bottom of the sleeve 22 is provided with a first clearance hole 221, the heating element 31 at least partially passes through the first clearance hole 221 and extends into the sleeve 22 along the axial direction; the battery rod assembly 4 is fixed in the bottom of the housing 1, and the battery rod assembly 4 is electrically connected to the driving assembly 21 and the heating element 31.

[0034] like Figure 2 , Figure 4 and Figure 6 As shown, by arranging a driving assembly 21 on the heat-not-burn device to drive the sleeve 22 to move up and down, the driving assembly 21 can be controlled by the battery rod assembly 4 to move the sleeve 22 up and down after the heating element 31 heats the cigarette 7, so that the sleeve 22 can be automatically extracted, so that no manual operation is required before taking the cigarette 7, simplifying the use steps of the device; and when the sleeve 22 moves up and down, it will be relatively displaced with the heating element 31, so that the heating element 31 and the cigarette 7 are loose and viscous and dispersed, and the tobacco material will not fall off or stay when taking the cigarette 7, thereby improving the user's use experience. Moreover, the extraction assembly 2 and the battery rod assembly 4 are respectively arranged in the top and bottom of the shell 1, which is not only novel in structure and simple in implementation, but also can make full use of the internal space of the shell 1, so that the outer dimensions of the heat-not-burn device will not be enlarged, and it is easy to hold.

[0035] It should be noted that the sleeve 22 is coaxially arranged with the insertion cavity 111, and the aperture of the first clearance hole 221 is smaller than the outer diameter of the cigarette 7, so as to ensure that the bottom of the sleeve 22 can support the cigarette 7. In actual use, after the cigarette 7 is inserted into the inner cavity of the sleeve 22 through the insertion cavity 111, the heating element 31 at least partially extends into the cigarette 7 and contacts the cigarette 7, and the heating element 31 can heat the cigarette 7 to generate smoke; when the heating is completed or stopped, the driving component 21 is controlled by the battery rod component 4, so that the driving component 21 drives the sleeve 22 to move up and down, so as to realize the automatic extraction of the cigarette 7, so that the cigarette is supported by the bottom of the sleeve and moves upward, and the relative displacement of the heating element and the cigarette makes the cigarette core separate from the stickiness, and there is no need to manually extract the sleeve 22 when pulling out the cigarette 7, so as to avoid the tobacco material falling off or being retained due to forgetting to extract the sleeve 22.

[0036] See also Figure 3 , Figure 4 and Figure 6The extraction assembly 2 further includes a transmission member 23, which is respectively connected to the sleeve 22 and the driving assembly 21, and the transmission member 23 is used to drive the sleeve 22 to move axially under the drive of the driving assembly 21. Among them, the driving assembly 21 can be a rotary motor, and the rotary motor drives the sleeve 22 to move up and down through the transmission member 23. According to actual needs, the driving assembly 21 can also be a linear motor, and the motor output is a linear motion. In this case, the sleeve 22 is assembled on the linear motor, and the linear motor directly drives the sleeve 22 to move up and down.

[0037] See also Figure 3 , Figure 5 and Figure 7 In some embodiments, the driving assembly 21 includes an annular stator 211 and an annular rotor 212. The annular stator 211 is fixed in the housing 1. The annular rotor 212 is rotatably arranged in the annular stator 211, and the annular rotor 212 rotates around the sleeve 22. The transmission member 23 and the annular rotor 212 are threadedly transmitted. Specifically, the annular stator 211 and the annular rotor 212 form a brushless motor. The annular stator 211 is provided with a coil, and the coil is electrically connected to the battery rod assembly 4. The annular rotor 212 is provided with a magnetic block. The coil generates a rotating magnetic field after being energized. The rotating magnetic field interacts with the magnetic field of the magnetic block on the annular rotor 212 to generate an electromagnetic force that drives the annular rotor 212 to rotate. Due to the threaded transmission between the transmission member 23 and the annular rotor 212 , when the annular rotor 212 rotates, the transmission member 23 and the annular rotor 212 cooperate with each other to move up and down, and the sleeve 22 also moves up and down under the drive of the transmission member 23 , realizing automatic control of the up and down movement of the sleeve 22 .

[0038] It should be understood that the annular stator 211 and the annular rotor 212 are both coaxially arranged with the sleeve 22, and the annular rotor 212 is arranged in the annular stator 211, which can greatly reduce the space occupied by the drive assembly 21 in the housing 1, making it easier to integrate the drive assembly 21 into the heating non-combustion appliance.

[0039] In other embodiments, the sleeve 22 may be assembled on a screw rod, and threaded transmission is provided between the sleeve 22 and the screw rod. The rotary motor drives the screw rod to rotate so as to move the sleeve 22 up and down.

[0040] See also Figure 2 , Figure 3 and Figure 5One end of the transmission member 23 is fixed to the sleeve 22, and the other end extends axially into the annular rotor 212, and the outer side of the end of the transmission member 23 extending into the annular rotor 212 is provided with a first thread 231, and the inner peripheral wall of the annular rotor 212 is provided with a second thread 2121. The transmission member 23 and the annular rotor 212 cooperate with each other through the first thread 231 and the second thread 2121 to form a thread transmission. Among them, the first thread 231 can be a sub-thread, and the second thread 2121 can be a female thread. When the annular rotor 212 rotates, the first thread 231 and the second thread 2121 cooperate with each other to generate a tangential force in the up and down directions, and the transmission member 23 moves up and down under the action of the tangential force.

[0041] In some embodiments, both ends of the transmission member 23 are connected, the inner cavity of the transmission member 23 is connected to the inner cavity of the sleeve 22, and the inner cavity of the transmission member 23 and the inner cavity of the sleeve 22 are both parts of the insertion cavity 111. Specifically, when inserting the cigarette 7, the cigarette 7 first passes through the inner cavity of the transmission member 23 and then falls into the inner cavity of the sleeve 22, so that the transmission member 23 can guide the insertion of the cigarette 7, which is convenient for the insertion of the cigarette 7.

[0042] In some embodiments, the transmission member 23 and the sleeve 22 are detachably connected or integrally arranged. Figure 2 and Figure 3 As shown, when the transmission member 23 is detachably connected to the sleeve 22, the transmission member 23 is sleeved on the outside of the sleeve 22 and snap-fitted with the sleeve 22; wherein a snap-fit ​​portion 224 may be provided on the outside of the sleeve 22, and a snap-fit ​​groove 233 may be provided on the inside of the transmission member 23, and the snap-fit ​​portion 224 and the snap-fit ​​groove 233 are snap-fitted together.

[0043] It should be noted that the cigarette 7 can be clamped by the housing 1 or the transmission member 23, wherein when the cigarette 7 is clamped by the housing 1, a plurality of ribs are arranged on the inner circumferential wall of the top of the housing 1 and are spaced apart along the circumferential direction, and the plurality of ribs interfere with the cigarette 7 to clamp the cigarette 7; when the cigarette 7 is clamped by the transmission member 23, the transmission member 23 is arranged in the cigarette clamping position area on the housing 1, and a plurality of ribs are arranged on the inner circumferential wall of the top of the transmission member 23 and are spaced apart along the circumferential direction, and the plurality of ribs interfere with the cigarette 7 to clamp the cigarette 7. The inner diameter of the sleeve 22 is slightly larger than the outer diameter of the cigarette 7, that is, after the cigarette 7 is inserted into the sleeve 22, there is a gap between the cigarette 7 and the inner circumferential wall of the sleeve 22, which can prevent the heat on the cigarette 7 from being transferred to the sleeve 22, prevent the temperature of the housing 1 from rising, and reduce the friction between the cigarette 7 and the inner circumferential wall of the sleeve 22 when the cigarette 7 is inserted or removed.

[0044] See also Figure 2 and Figure 3The transmission member 23 is sleeved on the outer side of the sleeve 22, and a limiting groove 232 is provided on the transmission member 23. The length of the limiting groove 232 extends along the axial direction. A limiting portion 222 is provided on the outer side of the sleeve 22, and the limiting portion 222 is embedded in the limiting groove 232. The limiting portion 222 cooperates with the limiting groove 232 to prevent the transmission member 23 from rotating relative to the sleeve 22, which is beneficial for the drive assembly 21 to drive the transmission member 23 and the sleeve 22 to move up and down. It should be understood that by providing the limiting groove 232 and the limiting portion 222, it is possible to avoid preventing the transmission member 23 from rotating relative to the sleeve 22 only by the buckling structure between the transmission member 23 and the sleeve 22, which is beneficial for avoiding damage to the buckling structure.

[0045] See also Figure 1 , Figure 4 and Figure 6 The housing 1 includes an upper housing 11 and a lower housing 12 detachably connected to the upper housing 11. The upper housing 11 has a plug-in cavity 111. The extraction component 2 is installed in the upper housing 11, and the heating component 3 and the battery rod component 4 are installed in the lower housing 12, so that the extraction component 2, the heating component 3 and the battery rod component 4 are distributed axially in the housing 1, so that the internal space of the housing 1 can be more reasonably utilized, which is conducive to reducing the external dimensions of the housing 1. Moreover, when the extraction component 2 is contaminated, the upper housing 11 can be disassembled to clean the extraction component 2, thereby facilitating the cleaning and maintenance of the extraction component 2.

[0046] See also Figure 2 , Figure 3 and Figure 7 The drive assembly 21 also includes a fixing frame 24 and a cover plate 25 fixed in the housing 1. The fixing frame 24 is provided with an installation cavity 241. The annular stator 211 is embedded and fixed in the installation cavity 241. The cover plate 25 is fixed to the fixing frame 24 and restricts the annular rotor 212 in the installation cavity 241. Specifically, the fixing frame 24 includes a bottom plate and a side plate fixed on the bottom plate. The side plate and the bottom plate are together enclosed to form an opening installation cavity 241; the cover plate 25 covers the opening of the installation cavity 241, thereby restricting the annular rotor 212 in the installation cavity 241, so that no rotating shaft is provided between the annular rotor 212 and the annular stator 211, simplifying the structure of the motor. Moreover, in the assembly process of the heating without burning appliance, the entire drive assembly 21 can be assembled first, and then the drive assembly 21 can be sleeved on the outside of the transmission member 23, thereby reducing the difficulty of assembly.

[0047] It should be noted that if Figure 2 , Figure 3 and Figure 4As shown, a second clearance hole 242 is provided on the bottom plate of the fixing frame 24, and a third clearance hole 251 is provided on the cover plate 25. The second clearance hole 242 and the third clearance hole 251 are connected to the uniform installation cavity 241. The transmission member 23 passes through the second clearance hole 242 and is threadedly assembled with the annular rotor 212. The cigarette 7 passes through the third clearance hole 251 and the second clearance hole 242 and is inserted into the sleeve 22.

The sleeve 22 is axially slidably assembled in the limiting sleeve 5, so that the sleeve 22 cannot rotate circumferentially, and the transmission member 23 is fixed to the sleeve 22, so that the transmission member 23 cannot rotate circumferentially.

[0049] The heating component 3 also includes a connecting frame 32 , which is fixed in the lower shell 12 , the heating element 31 is fixed to the connecting frame 32 , one end of the limiting sleeve 5 is fixed to the upper shell 11 , and the other end extends downward to connect with the connecting frame 32 .

[0050] See also Figure 3 In some embodiments, one of the limiting sleeve 5 and the sleeve 22 is provided with a guide portion 223, and the other is provided with a guide groove 51, the length of the guide groove 51 extends along the axial direction, and the guide portion 223 is arranged in the guide groove 51, so that the limiting sleeve 5 and the sleeve 22 can be slidably assembled, thereby preventing the sleeve 22 from rotating circumferentially. In a specific example, the guide groove 51 can be provided on the inner circumferential wall of the limiting sleeve 5, and the guide portion 223 can be provided on the outer side of the sleeve 22; two guide grooves 51 and two guide portions 223 can be provided, and the two guide grooves 51 and the two guide portions 223 are distributed at intervals along the circumferential direction. The number of guide grooves 51 and guide portions 223 is set according to actual needs, for example, one, three or four guide grooves 51 and guide portions 223 can be provided.

[0051] In practical applications, such as Figure 3 and Figure 4 As shown, after the heating element 31 stops heating or completes heating, the sleeve 22 is in the initial state, at which time the heating element 31 contacts and adheres to the cigarette 7, and then the battery rod assembly 4 controls the driving assembly 21 to rotate the annular rotor 212, as shown in FIG. Figure 6 and Figure 7 As shown, the sleeve 22 moves upward driven by the annular rotor 212 and the transmission member 23. After moving a certain distance, the annular rotor 212 stops rotating, and the sleeve 22 is in an extraction state. At this time, the cigarette 7 is extracted and raised by the sleeve 22, and the heating element 31 and the cigarette 7 are loosened and released from adhesion, and then the cigarette 7 is pulled out. Finally, the annular rotor 212 rotates in the opposite direction to restore the sleeve 22 to its initial state.

[0052] See also Figure 1 , Figure 5 and Figure 7 The heating non-combustion appliance also includes a sealing member 6, which is fixed in the bottom of the limiting sleeve 5 and seals the bottom opening of the limiting sleeve 5, and the sealing member 6 is sleeved on the outside of the heating element 31; wherein, the sealing member 6 can be a silicone member, and the sealing member 6 can prevent impurities in the sleeve 22 from falling into the lower shell 12 through the bottom opening of the limiting sleeve 5 to contaminate the battery rod assembly 4.

The main board 43 is electrically connected to the battery 41, the heating element 31 and the driving assembly 21. When the heating element 31 stops heating or the heating is completed, the main board 43 controls the driving assembly 21 through a preset program, and the driving assembly 21 drives the sleeve 22 to move up and down, so that the heating element 31 and the cigarette 7 are loosened, so that the cigarette 7 and the heating element 31 are in contact and sticky contact, and the grass material will not fall off or stay when the cigarette 7 is pulled out.

[0054] See also Figure 1 , Figure 4 and Figure 6 , the battery rod assembly 4 also includes an insulating aluminum cover 44, a button 45, a light guide ring 46 and an interface 47.
