Description

Technical Field

[0001] The present invention relates to the technical field of heating without burning appliances, and in particular to a heating without burning appliance. Background Art

[0002] A heat-not-burn device is a smoking device that heats cigarettes to generate smoke for users to inhale. The heating methods of heat-not-burn devices are generally central heating and peripheral heating. For heat-not-burn devices that use central heating, the heating element is inserted into the cigarette, and the tobacco material (tobacco shreds and / or tobacco leaves) in the cigarette is heated to generate smoke. After heating, the cigarette will adhere to the heating component, and the tobacco material is easy to fall off or remain when the cigarette is taken out. For this reason, an extractor is generally provided in a heat-not-burn device that uses central heating as an auxiliary cigarette removal structure. The extractor can move the cigarette up and down relative to the heating element, thereby dispersing the viscosity of the cigarette and the heating element.

[0003] In the related art, the extractor can be controlled by a motor, specifically, the motor drives the extractor to move up and down through a screw. However, since the cigarette will move up and down relative to the heating element, the heating element will be exposed because it is not in contact with the cigarette, causing the heating element to burn dry. 。 In order to prevent the heating element from dry burning during the process of viscous dispersion and separation of the cigarette and the heating element, the extractor either works after normal heating is completed or after the device is forced to shut down, which makes the use of the extractor relatively limited and cannot meet the user's usage needs. Summary of the invention

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Example:

[0033] See also Figures 1 to 7The embodiment of the present invention provides a heating-not-burning device, comprising a housing 1, a separation 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 6; the separation assembly 2 is installed in the housing 1, and the separation assembly 2 includes a driving assembly 21, a sleeve 22 and a clamping member 23, the sleeve 22 is connected to the insertion cavity 111 to accommodate the cigarette 6, and the clamping member 23 is connected to the driving assembly 21, the driving assembly 21 is used to drive the clamping member 23 to rotate around the central axis of the insertion cavity 111, and the clamping member 23 is used to clamp the cigarette 6; the heating assembly 3 includes a heating element 31 fixed in the housing 1, and a first clearance hole 221 is provided at the bottom of the sleeve 22, and the heating element 31 at least partially extends into the sleeve 22 along the axial direction; the battery rod assembly 4 is fixed in the housing 1, and the battery rod assembly 4 is electrically connected to the driving assembly 21 and the heating element 31.

[0034] Since the clamping member 23 clamps the cigarette 6 and the driving component 21 drives the clamping member 23 to rotate, the driving component 21 can control the cigarette 6 to rotate relative to the heating element 31, so that the heating element 31 and the cigarette 6 are loosened and the adhesive is dispersed and separated; when the clamping member 23 rotates, the heating element 31 always keeps in contact with the cigarette 6, and the heating element 31 will not be exposed in the sleeve 22, so that the heating element 31 will not dry burn during the process of adhesive dispersion and separation between the heating element 31 and the cigarette 6, so that the clamping member 23 can be driven to rotate at any time (during heating or after heating is completed), so that the user can take out the cigarette 6 at any time without residual tobacco substances in the sleeve 22, thereby meeting the user's usage needs.

[0035] It should be noted that when the heating element 31 is heating, the heating status of the cigarette 6 can be checked or the smoking can be interrupted by taking out the cigarette 6 (for a short time). If the heating of the cigarette 6 is found to be abnormal, the device can be manually forced to close. The sleeve 22 is coaxially arranged with the insertion cavity 111. The bottom of the sleeve 22 is closed and the top is open. 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 to extend into the sleeve 22; the diameter of the inner cavity of the sleeve is larger than the outer diameter of the cigarette 6 to ensure that the sleeve 22 can accommodate the cigarette 6. After the cigarette 6 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 6 and contacts the cigarette 6, so that the heating element 31 can heat the cigarette 6 to generate smoke.

[0036] In actual use, a control program can be preset on the battery rod assembly 4 so that the user can take out the cigarette 6 at any time to check the heating status of the cigarette 6 or interrupt smoking. For example, the battery rod assembly 4 controls the driving assembly 21 to drive the clamping member 23 to make multiple reciprocating rotations (parameter C, such as first rotating 90° clockwise, then rotating 90° counterclockwise, and making two reciprocating rotations within two seconds) during the preheating stage of the heating element 31 (such as the preheating time is six seconds, parameter A), and after four seconds of preheating (parameter B), to ensure that no tobacco material will fall off or remain when the cigarette 6 is taken out at any time during the preheating stage; during the heating stage of the heating element 31 (when smoking while the heating element 31 is heating), After every three puffs (parameter D), the drive assembly 21 is controlled to drive the clamping member 23 to make multiple reciprocating rotations (parameter E) to ensure that no tobacco material will fall off or remain when the cigarette 6 is taken out at any time during the heating stage; one second after the heating element 31 is heated (parameter E), the drive assembly 21 is controlled to drive the clamping member 23 to make multiple reciprocating rotations (parameter F), so that the cigarette 6 can be taken out after the heating of the cigarette 6 is completed without causing the tobacco material to fall off or remain; wherein, a touch screen can be provided on the device, and the parameters AF can be changed on the touch screen. The start-stop switch of the drive assembly 21 can also be provided on the device, for example, when the start-stop switch is pressed, the drive assembly 21 is operated, and the drive assembly 21 drives the clamping member 23 to make multiple reciprocating rotations and then stops, and at this time, the cigarette 6 is taken out without the tobacco material falling off or remaining.

[0037] See also Figure 2 , Figure 4 and Figure 5 The two ends of the clamping member 23 are connected to form a cavity 231, the diameter of the cavity 231 is the same as the diameter of the cigarette 6, and a limiting structure is provided on the inner peripheral wall of the clamping member 23, the limiting structure is used to prevent the cigarette 6 from rotating in the cavity 231 in the circumferential direction, and ensure that the cigarette 6 rotates with the clamping member 23 in the cavity 231. It should be understood that the clamping structure cannot completely fix the cigarette 6 in the cavity 231 through the limiting structure, that is, the cigarette 6 can still move axially to ensure the normal insertion and removal of the cigarette 6.

[0038] See also Figure 5 , Figure 6 and Figure 7The limiting structure includes a plurality of ribs 232 fixed to the clamping member 23, the plurality of ribs 232 are spaced apart in the circumferential direction, and the length of each rib 232 extends in the axial direction. When the cigarette 6 is accommodated in the cavity 231, each rib 232 contacts the cigarette 6, and the plurality of ribs 232 interfere and squeeze the cigarette 6, so that while the cigarette 6 is clamped in the cavity 231, the cigarette 6 can also be driven to rotate when the clamping member 23 rotates in the circumferential direction. Specifically, the clamping member 23 can be cylindrical, and the inner diameter of the cavity 231 is adapted to the outer diameter of the cigarette 6, which is conducive to the ribs 232 contacting and squeezing the cigarette 6. The two ends of the ribs 232 extend to the two ends of the clamping member 23 respectively, so that the length of the ribs 232 can be longer, which is conducive to improving the interference and squeezing effect between the plurality of ribs 232 and the cigarette 6. A plurality of ribs 232 are distributed at equal angles around the central axis of the cavity 231, wherein the number of ribs 232 is between 8 and 10. For example, 8 ribs 232 may be provided, and the 8 ribs 232 are distributed at equal angles around the central axis of the cavity 231, so that the interference and squeezing effect of the ribs 232 on the cigarette 6 is optimal. According to actual needs, the number of ribs 232 may also be set to three, four, etc.

[0039] In some embodiments, the limiting structure can be a pin disposed on the inner circumferential wall of the clamp 23, the tail of the pin is elastically connected to the clamp 23, the top of the pin radially extends into the cavity 231, and the top is an elliptical structure, a plurality of pins are provided and the plurality of pins are distributed circumferentially, the diameter of the inner cavity enclosed by the plurality of pins in a natural state is smaller than the outer diameter of the cigarette 6, and the plurality of pins clamp the cigarette 6 together so that the cigarette 6 cannot rotate circumferentially. The rib 232 can be formed by protruding inwardly from the inner circumferential wall surface of the clamp 23 to a certain height, that is, the rib 232 and the clamp 23 are integrally arranged, so that the rib 232 and the clamp 23 can be integrally formed, and the forming method is simple. Alternatively, the rib 232 and the clamp 23 are separately arranged, and a mounting groove can be arranged on the inner circumferential wall surface of the clamp 23, and the rib 232 is embedded and fixed in the mounting groove.

[0040] Preferably, the side of the rib 232 away from the inner peripheral wall of the clamp 23 is provided with stripes, which can enhance the friction between the rib 232 and the cigarette 6, so as to help the stripes prevent the cigarette 6 from rotating in the circumferential direction. Both ends of the rib 232 are provided with guide slopes 2321, which are used to guide the axial movement of the cigarette 6 in the cavity 231. The guide slopes 2321 can be formed by chamfering the ends of the rib 232. The guide slopes 2321 can make the axial movement of the cigarette 6 smoother, so as to facilitate the insertion and removal of the cigarette 6.

[0041] The material of the clamping member 23 includes any one of polyetheretherketone and polyaryletherketone, preferably polyetheretherketone, which has low cost, high temperature resistance, stable rigidity and low thermal conductivity, and is conducive to improving the stability of the clamping member 23 in clamping the cigarette 6. In addition, when the heating element 31 is heated, the clamping member 23 can absorb a small amount of heat, and polyetheretherketone and polyaryletherketone will expand when heated, so that the clamping member 23 will expand after absorbing heat, thereby making the contact between the clamping member 23 and the cigarette 6 closer.

[0042] In some embodiments, the clamping member 23 is provided with a cavity 231 and the diameter of the cavity 231 is smaller than the diameter of the cigarette 6. The inner circumferential wall of the clamping member 23 is elastic. During the insertion of the cigarette 6, the cigarette 6 will stretch the inner circumferential wall of the clamping member 23 to expand the cavity 231, thereby ensuring the smooth insertion of the cigarette 6. After the insertion is completed, the inner circumferential wall of the clamping member 23 contracts under the action of the restoring force to reduce the size of the cavity 231, which is conducive to the clamping member 23 clamping the cigarette.

[0043] In some embodiments, the clamping member 23 is provided with a cavity 231, and an elastic member is provided on the inner circumferential wall of the clamping member 23, and the maximum distance between the elastic member and the inner circumferential wall of the clamping member 23 is smaller than the diameter of the cigarette, so that the cigarette 6 can be clamped by the clamping member 23 under the elastic force of the elastic member; wherein, a plurality of elastic members can be provided, and the plurality of elastic members are distributed at intervals along the circumferential direction, and the plurality of elastic members together enclose a clamping cavity to clamp the cigarette 6.

[0044] See also Figure 1 and Figure 3 The shell 1 includes an upper shell 11 and a lower shell 12 connected to the upper shell 11. The upper shell 11 has a plug-in cavity 111. The separation component 2 is installed in the upper shell 11, and the battery rod component 4 is installed in the lower shell 12. A part of the heating component 3 is arranged in the upper shell 11, and the other part is arranged in the lower shell 12, so that the separation component 2, the heating component 3 and the battery rod component 4 are distributed axially in the shell 1, so that the internal space of the shell 1 can be more reasonably utilized, which is conducive to reducing the external dimensions of the shell 1.

[0045] See also Figure 2 , Figure 3 and Figure 4The 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. The clamping member 23 is embedded and fixed in the annular rotor 212. Specifically, the annular stator 211 and the annular rotor 212 form a brushless motor. The annular stator 211 is provided with a coil, which 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. Since the clamping member 23 is fixed in the annular rotor 212, when the annular rotor 212 rotates, it will drive the clamping member 23 to rotate, and the cigarette 6 rotates with the clamping member 23.

[0046] 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 and facilitate the drive assembly 21 to be arranged in the upper shell 11.

[0047] In some embodiments, one of the inner circumferential wall of the annular rotor 212 and the outer side of the clamping member 23 may be provided with a positioning groove 2121, and the other may be provided with a positioning portion 233. The length of the positioning groove 2121 extends along the axial direction, and the positioning portion 233 is embedded and fixed in the positioning groove 2121 to ensure the firmness of the connection between the annular rotor 212 and the clamping member 23. For example, Figure 2 As shown, a positioning groove 2121 can be provided on the inner circumferential wall of the annular rotor 212, one end of the positioning groove 2121 extends axially to the end of the annular rotor 212, and a positioning portion 233 is provided on the outer side of the clamping member 23. During the assembly process of the clamping member 23 and the annular rotor 212, the positioning portion 233 is axially inserted into the positioning groove 2121.

[0048] See also Figure 2 and Figure 4The drive assembly 21 further includes a bottom shell 213 and an upper cover 214. The bottom shell 213 is provided with a receiving cavity 2131. The annular stator 211 is fixed in the receiving cavity 2131. The upper cover 214 is fixed to the bottom shell 213 and covers the receiving cavity 2131 to limit the annular rotor 212 in the receiving cavity 2131, so that no rotating shaft is provided between the annular rotor 212 and the annular stator 211, thereby simplifying the structure of the motor. The bottom shell 213 and the sleeve 22 are connected as one body, and the bottom shell 213 is arranged on the top of the sleeve 22, so that in the assembly process of the heating without burning device, the annular stator 211, the annular rotor 212 and the clamping member 23 can be installed in the receiving cavity 2131 first, and then the upper cover 214 is covered, and then the sleeve 22 is installed in the upper shell 11, and the step of installing the drive assembly 21 alone in the upper shell 11 can be omitted, thereby simplifying the assembly steps of the device. According to actual needs, the bottom shell 213 and the sleeve 22 can also be provided separately.

[0049] See also Figure 2 and Figure 4 The bottom shell 213 is provided with a second clearance hole 2132, which is respectively connected to the sleeve 22 and the accommodating chamber 2131; the upper cover 214 is provided with a third clearance hole 2141, which is respectively connected to the accommodating chamber 2131 and the insertion chamber 111. When the cigarette 6 is inserted, the cigarette 6 passes through the insertion chamber 111, the third clearance hole 2141 and the second clearance hole 2132 in sequence, and extends into the sleeve 22.

[0050] See also Figure 1 , Figure 3 and Figure 5 The heating component 3 also includes an enclosure frame 32 and a support frame 33. The enclosure frame 32 is fixed in the housing 1 and connected at both ends. The enclosure frame 32 is sleeved on the outside of the sleeve 22. There is a gap between the inner wall of the enclosure frame 32 and the outside of the sleeve 22 to prevent the heat on the sleeve 22 from being directly transferred to the enclosure frame 32, thereby preventing heat loss. The support frame 33 is fixed to the bottom end of the enclosure frame 32. The heating element 31 is fixed to the support frame 33 and one end extends axially into the sleeve 22, so that the heating element 31 can contact the cigarette 6 and heat the cigarette 6.

[0051] See also Figure 4 The heating non-combustion appliance also includes a sealing member 5, which is fixed to the bottom of the enclosure frame 32 and seals the bottom opening of the enclosure frame 32, and the sealing member 5 is sleeved on the outside of the heating element 31; wherein the sealing member 5 can be a silicone member, and the sealing member 5 can prevent impurities in the sleeve 22 from falling into the lower shell 12 through the bottom opening of the enclosure frame 32 to contaminate the battery rod assembly 4.

[0052] See also Figure 1 and Figure 3The battery rod assembly 4 includes a battery 41, a mounting frame 42 and a main board 43. The mounting frame 42 is fixed in the lower shell 12. The battery 41 and the main board 43 are both fixed to the mounting frame 42 and are arranged on both sides of the mounting frame 42. The main board 43 is electrically connected to the battery 41, the heating element 31 and the driving assembly 21. The main board 43 controls the driving assembly 21 through a preset program so that the driving assembly 21 drives the clamping member 23 to rotate, and the cigarette 6 rotates with the clamping member 23, so that the heating element 31 and the cigarette 6 are loosened, thereby releasing the adhesion between the cigarette 6 and the heating element 31, and the grass substance will not fall off or remain when the cigarette 6 is taken out.

[0053] In some embodiments, a sensor can also be provided in the heating non-combustion device, and the sensor is electrically connected to the main board 43. The sensor can detect the airflow temperature or resistance during puffing. The main board 43 can judge the number of puffs after comparing the detection data of the sensor with a preset threshold value, and adjust the rotation time and rotation speed of the clamp 23 according to the number of puffs. For example, one second after the first puff ends, the main board 43 controls the drive component 21 to rotate 90° clockwise, then 90° counterclockwise, and make two reciprocating rotations within two seconds; one second after the fifth puff ends, the main board 43 controls the drive component 21 to rotate 90° clockwise, then 90° counterclockwise, and make three reciprocating rotations within two seconds.

[0054] See also Figure 1 and Figure 3 The battery rod assembly 4 also includes an insulating aluminum cover 44, a button 45, a light-blocking silicone 46, a light guide ring 47 and an interface 48. The insulating aluminum cover 44 is fixed in the lower shell 12, and the battery 41, the mounting frame 42 and the main board 43 are all fixed in the insulating aluminum cover 44. There is a gap between the insulating aluminum cover 44 and the inner wall of the lower shell 12 to prevent heat from being transferred to the lower shell 12, so that the lower shell 12 maintains a lower temperature and improves the comfort of holding. The button 45 is fixed to the outside of the lower shell 12, and the button 45 is electrically connected to the main board 43 and the power supply. The button 45 is used to start or shut down the heating without burning device. The light-blocking silicone 46, the light-guiding ring 47 and the interface 48 are all fixed to the bottom of the lower shell 12. An indicator light is provided on the main board 43. The light-blocking silicone 46 is used to block the light beam emitted by the indicator light from diverging in all directions. The light-guiding ring 47 is used to transmit the light beam emitted by the indicator light to the surface of the lower shell 12. The interface 48 is electrically connected to the battery 41, and the interface 48 is used to provide a charging port for the battery 41.
