Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, in particular to a heating without burning device. Background Art

[0002] A heat-not-burn device, also called a low-temperature non-burning heating device, is an electronic device that heats herbal products (such as low-temperature non-burning cigarettes, referred to as cigarettes) at low temperatures (generally 200-400°C) to form a smokeless aerosol. Compared with traditional burning cigarettes, the heat-not-burn device has a low operating temperature and the harmful components in the aerosol it produces are far lower than those of traditional burning cigarettes. Therefore, the use of a heat-not-burn device can greatly reduce the adverse effects of traditional cigarettes on the human body.

[0003] In the related art, an internal heat-not-burn device is one type of heat-not-burn device. This type of heat-not-burn device is usually provided with a cavity for accommodating herbal products and a heating body for heating and atomizing the herbal products. When in use (taking the herbal products as cigarettes as an example), the cigarettes are loaded into the cavity and the heating body is inserted into the interior of the cigarettes. Then, the heat generated by the heating body is used to heat and atomize the cigarettes from the inside out to produce an aerosol for the user to inhale.

[0004] When the active ingredients (such as nicotine) in the cigarette are consumed, a new cigarette can be replaced for continued smoking. When replacing cigarettes, it is usually necessary to manually pull out the used cigarette (i.e., the remaining cigarette) from the heating body. However, since the heated and atomized cigarette is easily adhered to the surface of the heating body, it is easy for the user to only remove part of the remaining cigarette when manually pulling out the remaining cigarette due to uneven or unstable force, while the other part of the remaining cigarette remains on the heating body, which will affect the user's next use. For example, the user cannot smoothly insert a new cigarette into the cavity of the heat-not-burn device when using it next time. Utility Model Content

[0061] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0062] Please refer to Figures 1 to 11 The embodiment of the utility model provides a heat-not-burn device, which is used to heat a herbal product 9 to generate an aerosol that can be inhaled by a user. Specifically, the heat-not-burn device includes a main shell 1, an inner sleeve 2, a heating body 3, a driving member 4 and an operating member 5, wherein:

[0063] The inner sleeve 2 is movably installed in the main shell 1 , and a receiving cavity 20 for accommodating the herbal product 9 is provided inside the inner sleeve 2 , and a bottom plate portion 21 for supporting the herbal product 9 is provided at the bottom of the inner sleeve 2 .

[0064] The heating body 3 includes a heating part 31 and a mounting part 32. The mounting part 32 is fixed in the main shell 1 and is arranged below the bottom plate part 21. The heating part 31 is partially located in the accommodating cavity 20, and the lower end of the heating part 31 passes through the bottom plate part 21 and is fixedly connected to the mounting part 32.

[0065] The driving member 4 is rotatably mounted in the main housing 1, and one end of the driving member 4 is in close contact with the outer wall of the inner sleeve 2. It should be noted that in a specific implementation, one end of the driving member 4 can abut or connect with the outer wall of the middle part of the inner sleeve 2, or with the bottom wall of the inner sleeve 2, or with the outer wall of the bottom of the inner sleeve 2, as long as it can meet the use requirements. This embodiment does not impose specific restrictions on this. For example, Figure 2-4 as well as Figure 8-10 As shown, one end of the driving member 4 abuts against the bottom outer wall of the inner sleeve 2. Specifically, one end of the driving member 4 abuts against the bottom outer wall of the inner sleeve 2. It should be noted here that when one end of the driving member 4 is connected to the outer wall of the inner sleeve 2, the connection method can be a snap connection, a threaded connection, etc., as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this.

[0066] One end of the operating member 5 is in close contact with the driving member 4, and the other end is exposed outside the main housing 1. The operating member 5 is used to drive the driving member 4 to rotate along the first rotation direction to drive the inner sleeve 2 to move relative to the heating portion 31 in a direction away from the mounting portion 32. It can be understood here that, for example, the first rotation direction is as follows: Figure 2-4 as well as Figure 8-10 Clockwise direction in the structure shown.

[0067] In this embodiment, it should be noted that the above-mentioned herbal product 9 can be a low-temperature non-burning cigarette, or a herbal substance (such as tea, etc.), and of course it can also be other types of herbal products 9, which can be determined according to the actual use needs of the user, and this embodiment does not impose specific restrictions on this. It should be noted that the so-called low-temperature non-burning cigarette mainly refers to an aerosol-generating product made of tobacco shreds, tobacco particles, plant fragments, tobacco flavors, propylene glycol and other materials. Under low-temperature heating conditions, nicotine and other flavor substances inside the herbal product 9 can evaporate without generating solid particles, and only atomized steam is generated. Low-temperature non-combustion is actually a low-temperature dry distillation process, and its heating temperature is generally between 200°C and 400°C. The low temperature here refers to the temperature within the range of 200°C to 400°C. In addition, it should be noted that in a specific application scenario, the shape of the herbal product 9 can be fixed (for example, it can be a columnar low-temperature non-burning cigarette) or it can be unfixed (for example, it can be loose tobacco shreds), and this embodiment does not impose specific restrictions on this. For the convenience of understanding and explanation, each embodiment of the present invention is described by taking the herbal product 9 as a low-temperature non-burning cigarette as an example.

[0068] In this embodiment, it should be noted that in the specific implementation, the structure of the driving member 4 can be a cam structure (such as Figure 8-11 As shown), it can also be a lever structure (as Figure 2-7 As shown), of course, it can also be other structures that can convert their own rotational motion into linear motion of the inner sleeve 2, as long as it can meet the use requirements, and this embodiment does not make any specific restrictions on this.

[0069] Based on the above structural design, the use principle of the heating without burning device provided in this embodiment is as follows:

[0070] like Figure 2-3 as well as Figure 8-10 As shown, when the user needs to use the heat-not-burn device for inhalation, the herbal product 9 to be heated can be loaded into the accommodating cavity 20 of the inner sleeve 2, so that the heating portion 31 of the heating body 3 located in the accommodating cavity 20 is inserted into the interior of the herbal product 9, and the bottom of the herbal product 9 is in contact with the bottom plate portion 21 of the inner sleeve 2, and then the heating function of the heat-not-burn device is turned on, and the heat generated by the heating portion 31 is used to heat and atomize the herbal product 9, thereby generating an aerosol that can be inhaled by the user;

[0071] like Figure 4 and Fig.10As shown, when the herbal product 9 becomes residual smoke after being heated and atomized and needs to be replaced, the user can apply external force to the end of the operating member 5 exposed outside the main shell 1 by hand, so that the operating member 5 drives the driving member 4 to rotate along the first rotation direction. During the rotation of the driving member 4 along the first rotation direction, the inner sleeve 2 will be driven to move in a direction away from the mounting portion 32 (that is, the inner sleeve 2 will move upward). Since the bottom of the residual smoke is in contact with the bottom plate portion 21 of the inner sleeve 2, during the movement of the inner sleeve 2 in the direction away from the mounting portion 32, the bottom plate portion 21 of the inner sleeve 2 will push the residual smoke upward. The inner sleeve 2 and the residual smoke as a whole move relative to the heating part 31 in a direction away from the mounting part 32, that is, the residual smoke and the heating part 31 of the heating body 3 will move relative to each other, so that the adhesion between the residual smoke and the heating part 31 can be destroyed in advance, so that the user can easily remove all the residual smoke by hand later. After removing all the residual smoke, the new herbal product 9 can be loaded into the inner sleeve 2 and the smoking can be continued. That is, in the process of replacing the herbal product 9, the risk of residual smoke remaining on the heating body 3 can be effectively reduced to avoid adverse effects on the user's next use. It should be noted here that in the specific implementation, the distance of relative movement between the residual smoke and the heating part 31 of the heating body 3 (that is, the distance that the inner sleeve 2 and the residual smoke as a whole move upward relative to the heating part 31) can be flexibly set according to actual needs, for example, it can be 1mm, 1.5mm, 2mm, 3mm, etc., as long as the adhesion between the residual smoke and the heating part 31 can be destroyed in advance, so that the user can easily remove all the residual smoke by hand later, this embodiment does not impose specific restrictions on this.

[0072] Furthermore, in order to facilitate the installation of components such as the inner sleeve 2 in the main housing 1 during the production of the heat-not-burn device, in some optional embodiments, such as Figure 2-5 as well as Figure 8-11 As shown, the heating without burning device also includes an inner bracket 72, and the main shell 1 can specifically include an upper cover body 11 and a main shell 12. The lower end of the upper cover body 11 can be detachably connected to the upper end of the main shell 12 by means of threaded connection, plug-in, etc., and a socket 110 is provided on the upper cover body 11 for inserting the herbal product 9 into the accommodating cavity 20 of the inner sleeve 2. Specifically, the socket 110 is connected to the cavity opening of the accommodating cavity 20 of the inner sleeve 2 in correspondence; the inner sleeve 2 is movably installed in the upper cover body 11 through the inner bracket 72. Specifically, the inner bracket 72 is fixedly connected to the upper cover body 11, and the inner sleeve 2 is movably mounted on the inner bracket 72 by means of clearance fit, etc.; the mounting portion 32 of the heating body 3 is fixedly connected to the main shell 12.

[0073] Furthermore, in some optional embodiments of the present invention, the structure of the operating member 5 may be as follows:

[0074] Please refer to Figure 1-4 , the operating member 5 includes a push rod 51 that is slidably connected to the main housing 1, one end of the push rod 51 is in contact with or connected to the end of the driving member 4 away from the inner sleeve 2, and the other end of the push rod 51 is exposed outside the main housing 1; wherein, as shown in FIG. 4 , when the other end of the push rod 51 is pressed by an external force and drives the driving member 4 to rotate along the first rotation direction (i.e., clockwise), the end of the driving member 4 close to the inner sleeve 2 pushes the inner sleeve 2 to move in a direction away from the mounting portion 32, so that the residual smoke can move upward relative to the heating portion 31 along with the inner sleeve 2 as a whole, so that the adhesion between the residual smoke and the heating portion 31 can be destroyed, so that the user can easily remove all the residual smoke by hand later. It should be noted here that when one end of the push rod 51 is connected to the end of the driving member 4 away from the inner sleeve 2, the connection method can be a snap connection, a threaded connection, etc., as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this.

[0075] In this embodiment, it should be noted that, in a specific implementation, the other end of the push rod 51 (i.e., the end of the push rod 51 away from the driving member 4) can be exposed from the side wall of the main housing 1 (this is equivalent to arranging the push rod 51 horizontally), or can be exposed from the top of the main housing 1 (this is equivalent to arranging the push rod 51 longitudinally, such as Figure 2-4 As shown), it can be flexibly set according to actual needs. Figure 1-4 As shown, the push rod 51 moves in the same direction as the movement direction of the inner sleeve 2 (i.e. Figure 1-5 The push rod 51 is extended in the upper and lower directions as shown, and the other end of the push rod 51 is exposed from the top of the main shell 1. Exemplarily, the upper end of the push rod 51 passes through the inner bracket 72 and the upper end surface of the upper cover body 11 in sequence and then is exposed from the top of the upper cover body 11. In this way, compared with exposing the other end of the push rod 51 from the side wall of the main shell 1, on the one hand, it can avoid the relative movement between the herbal product 9 and the heating part 31 due to accidentally touching the other end of the push rod 51 when the user holds the outer peripheral side wall of the main shell 1 for inhalation, thereby preventing the contact area between the heating part 31 and the herbal product 9 from becoming smaller and affecting the amount of aerosol generated; on the other hand, it is more ergonomically designed, so that when the user finishes inhaling and needs to remove the residual smoke, the other end of the push rod 51 can be pressed more conveniently.

[0076] In the present embodiment, it can be understood that after pressing the other end of the push rod 51 and taking out the residual cigarette, in order to ensure that the subsequent residual cigarette can be easily taken out again during subsequent use, it is usually necessary to reset the inner sleeve 2, the drive member 4 and the operating member 5. Optionally, in some usage scenarios, the inner sleeve 2, the drive member 4 and the operating member 5 can be reset by manual operation. Specifically, in the process of inserting a new herbal product 9 into the inner sleeve 2, the bottom of the herbal product 9 will push down the bottom plate portion 21 of the inner sleeve 2, so that the inner sleeve 2 moves downward and resets to the initial position. In the process of the inner sleeve 2 moving downward, the inner sleeve 2 will drive the drive member 4 to reset to the initial position, and at the same time, the drive member 4 will drive the operating member 5 to reset to the initial position.

[0077] Furthermore, in order to facilitate the resetting of the inner sleeve 2, the driving member 4 and the operating member 5, in some optional embodiments of the present utility model, the heat without burning device may be structurally designed as follows:

[0078] For details, please refer to Figure 2-4 The heating without burning device further comprises an elastic member 61 disposed in the main housing 1, the elastic member 61 being arranged in the same direction as the movement direction of the inner sleeve 2 (i.e. Figure 1-5 The elastic member 61 is provided to extend in the up-down direction as shown, or in the height direction of the heating without burning device, one end of the elastic member 61 is fixed relative to the main shell 1, and the other end of the elastic member 61 is fixed relative to one of the driving member 4 and the push rod 51. For example, the lower end of the elastic member 61 is fixed relative to the main shell 12 of the main shell 1, and the upper end of the elastic member 61 abuts against the lower side of the end of the driving member 4 away from the inner sleeve 2. In this way, by adding the elastic member 61, when the user needs to break the adhesion between the residual smoke and the heating part 31 and presses the upper end of the push rod 51, the elastic member 61 will be in a compressed state, and then when the user removes the pressing force applied to the upper end of the push rod 51, under the action of the elastic restoring force of the elastic member 61, the driving member 4 will rotate along the second rotation direction (it can be understood here that the second rotation direction is opposite to the first rotation direction, and the second rotation direction is as shown in FIG. 2 ). Figure 2-4 In the process of the driving member 4 rotating along the second rotation direction, the end of the driving member 4 connected to the inner sleeve 2 will drive the inner sleeve 2 to move downward to the initial position. At the same time, the end of the driving member 4 connected to the push rod 51 will drive the push rod 51 to move upward to the initial position, thereby realizing the automatic resetting of the inner sleeve 2, the driving member 4 and the operating member 5 without the need for the user to manually reset the inner sleeve 2, the driving member 4 and the operating member 5. Compared with the manual resetting method by inserting a new herbal product 9 into the inner sleeve 2, when replacing a new herbal product 9, the new herbal product 9 can be more stably loaded into the inner sleeve 2 and is not prone to breakage.

[0079] In this embodiment, it can be understood that in some specific implementations, when the elastic member 61 is installed in a manner that one end of the elastic member 61 is fixed relative to the main shell 1 and the other end of the elastic member 61 is fixed relative to the push rod 51, the lower end of the elastic member 61 can be abutted against the inner bracket 72, and the upper end of the elastic member 61 can be fixedly connected to the upper end outer wall of the push rod 51.

[0080] In this embodiment, it should be noted that, in specific implementation, the elastic member 61 can be a spring, a spring sheet, a rubber band or other element with good elastic properties, as long as it can meet the use requirements, and this embodiment does not impose any specific restrictions on this.

[0081] In this embodiment, it should also be noted that the operation of manually removing the residual smoke can be performed before the user removes the pressing force applied to the upper end of the push rod 51, or after the user removes the pressing force applied to the upper end of the push rod 51. It can be flexibly operated according to actual needs, and this embodiment does not impose specific restrictions on this. It can be understood here that when the operation of manually removing the residual smoke is performed after the user removes the pressing force applied to the upper end of the push rod 51, it is equivalent to two relative movements between the residual smoke and the heating part 31 before the residual smoke is removed, which is more conducive to destroying the adhesion between the residual smoke and the heating part 31, and is also conducive to saving the effort applied by the user to the push rod 51.

[0082] Furthermore, in some other optional embodiments, in addition to realizing the automatic resetting of the inner sleeve 2, the driving member 4 and the operating member 5 by adding an elastic member 61, the automatic resetting of the inner sleeve 2, the driving member 4 and the operating member 5 can also be realized by adding a permanent magnet 62. Specifically, the bottom plate portion 21 of the inner sleeve 2 is made of a magnetic material (such as iron, nickel-chromium-iron alloy, silicon steel and other magnetic materials), and the heating without burning device also includes a permanent magnet 62 (such as a magnet) fixed in the main shell 1, and the permanent magnet 62 is arranged below the bottom plate portion 21. In this way, after the user removes the pressing force applied to the upper end of the push rod 51, the attraction of the permanent magnet 62 to the bottom plate portion 21 can be used to drive the inner sleeve 2 to move downward to the initial position, thereby realizing the automatic resetting of the inner sleeve 2, the driving member 4 and the operating member 5. It should be noted here that, in specific implementation, the reset method of adding an elastic member 61 and the reset method of adding a permanent magnet 62 can be used either one or both, and can be flexibly selected according to actual needs, and this embodiment does not impose specific restrictions on this.

[0083] Further, in some optional embodiments of the present invention, please refer to Figure 2-7A groove 420 is formed at the top of the end of the driving member 4 away from the inner sleeve 2, and one end of the push rod 51 (i.e., the lower end of the push rod 51) extends into the groove 420 and abuts against the driving member 4. In this way, the groove 420 can play a certain limiting role on the push rod 51, so that the lower end of the push rod 51 can always abut against the end of the driving member 4 away from the inner sleeve 2 without slipping, so that the push rod 51 can more stably drive the driving member 4 to rotate along the first rotation direction.

[0084] Further, in some optional embodiments of the present invention, when the structure of the driving member 4 is a lever structure, the specific structure of the driving member 4 can be as follows:

[0085] Specifically, if Figure 2-7 As shown, the driving member 4 includes a prying portion 41, a force-bearing portion 42 and a rotating portion 43, the rotating portion 43 is rotatably installed in the main housing and is located between the prying portion 41 and the force-bearing portion 42, one end of the prying portion 41 abuts against the outer wall of the inner sleeve, and the other end smoothly transitions with the side of the rotating portion 43 close to the inner sleeve and is connected as a whole, the top of one end of the force-bearing portion 42 abuts against one end of the operating member, and the other end smoothly transitions with the side of the rotating portion 43 facing away from the inner sleeve and is connected as a whole, the surface of the side of the prying portion 41 facing away from the mounting portion is concavely provided with a first arc surface 411 located between the two ends of the prying portion 41, and the surface of the side of the force-bearing portion 42 facing away from the push rod is concavely provided with a second arc surface 421 located between the two ends of the force-bearing portion 42. In this way, compared with setting the driving member 4 as a straight bar-shaped lever-type structure, the irregular lever-type structure of this embodiment can play a technical effect of reducing the installation space required for the driving member 4.

[0086] Furthermore, in some other optional embodiments of the present invention, the structure of the operating member 5 may also be as follows:

[0087] For details, please refer to Figure 8-10 The operating member 5 includes a rack 52 and a pressure rod 53 slidably connected to the main housing 1. One end of the rack 52 is connected to one end of the pressure rod 53, and the other end of the rack 52 is meshed with the end of the driving member 4 away from the inner sleeve 2. The end of the pressure rod 53 away from the rack 52 is exposed outside the main housing 1; wherein, when the end of the pressure rod 53 away from the rack 52 is pressed by an external force, the driving member 4 is driven to rotate in the first direction (i.e., Figure 8-10 When the driving member 4 rotates in the clockwise direction (in the structure shown), the end of the driving member 4 close to the inner sleeve 2 pushes the inner sleeve 2 to move in the direction away from the mounting portion 32, so that the residual smoke can move upward relative to the heating portion 31 along with the inner sleeve 2 as a whole, thereby destroying the adhesion between the residual smoke and the heating portion 31, so that the user can easily remove all the residual smoke by hand later.

[0088] In this embodiment, it should be noted that, in a specific implementation, the end of the pressure rod 53 away from the rack 52 can be exposed from the side wall of the main housing 1 (this is equivalent to arranging the rack 52 and the pressure rod 53 horizontally), or can be exposed from the top of the main housing 1 (this is equivalent to arranging the rack 52 and the pressure rod 53 vertically, such as Figure 8-10 As shown), it can be flexibly set according to actual needs, and this embodiment does not impose specific restrictions on this. Preferably, as Figure 8-10 As shown, the pressure rod 53 and the rack 52 are both in the same direction as the movement direction of the inner sleeve 2 (i.e. Figure 8-10 52 is extended in the up and down direction shown, or the height direction of the heating non-combustion device, and the end of the pressure rod 53 away from the rack 52 is exposed from the top of the main shell 1. By way of example, the upper end of the pressure rod 53 passes through the inner bracket 72 and the upper end surface of the upper cover body 11 in sequence and then is exposed from the top of the upper cover body 11. In this way, compared with exposing the end of the pressure rod 53 away from the rack 52 from the side wall of the main shell 1, on the one hand, it can avoid the relative movement between the herbal product 9 and the heating part 31 due to accidentally touching the end of the pressure rod 53 away from the rack 52 when the user holds the outer peripheral side wall of the main shell 1 for inhalation, thereby preventing the contact area between the heating part 31 and the herbal product 9 from becoming smaller and affecting the amount of aerosol generated; on the other hand, it is more ergonomically designed, so that when the user finishes inhaling and needs to remove the residual smoke, the end of the pressure rod 53 away from the rack 52 can be pressed more conveniently.

[0089] In the present embodiment, it should also be noted that the meshing mode between the end of the rack 52 away from the pressure rod 53 and the end of the driving member 4 away from the inner sleeve 2 can be direct meshing or indirect meshing, and the present embodiment does not make specific restrictions on this. It can be understood that when the meshing mode between the end of the rack 52 away from the pressure rod 53 (i.e., the lower end of the rack 52) and the end of the driving member 4 away from the inner sleeve 2 is direct meshing, a tooth portion directly meshing with the lower end of the rack 52 is provided on the outer wall of the end of the driving member 4 away from the inner sleeve 2, and when the meshing mode between the lower end of the rack 52 and the end of the driving member 4 away from the inner sleeve 2 is indirect meshing, a gear portion coaxially arranged with the end of the driving member 4 away from the inner sleeve 2 can be added to the end of the driving member 4 away from the inner sleeve 2, so that the end of the driving member 4 away from the inner sleeve 2 can be indirectly meshed with the lower end of the rack 52 through the gear portion.

[0090] For further information, please refer to Figure 8-10 In some optional embodiments of the present invention, the heating without burning device further comprises an elastic member 61 disposed in the main housing 1, the elastic member 61 being arranged in the same direction as the movement direction of the inner sleeve 2 (i.e. Figure 8-11The elastic member 61 is extended in the up and down directions shown in the figure, or the height direction of the heating without burning device, one end of the elastic member 61 is fixed relative to the main shell 1, and the other end of the elastic member 61 is fixed relative to one of the rack 52 and the pressure rod 53. For example, the lower end of the elastic member 61 is fixed relative to the main shell 12 of the main shell 1, and the upper end of the elastic member 61 is in contact with the lower end of the rack 52. In this way, by adding the elastic member 61, when the user needs to break the adhesion between the residual smoke and the heating part 31 and presses the upper end of the pressure rod 53, the elastic member 61 will be in a compressed state, and then when the user removes the pressing force applied to the upper end of the pressure rod 53, under the action of the elastic restoring force of the elastic member 61, the rack 52 will move upward to the initial position together with the pressure rod 53 as a whole. In the process of the rack 52 and the pressure rod 53 moving upward to the initial position as a whole, the rack 52 will drive the driving member 4 to rotate along the second rotation direction (it can be understood here that the second rotation direction is opposite to the first rotation direction, and the second rotation direction is as follows Figure 8-10 When the driving member 4 rotates in the second rotation direction, it will drive the inner sleeve 2 to move downward to the initial position, thereby realizing the automatic resetting of the inner sleeve 2, the driving member 4 and the operating member 5 without the need for the user to manually reset the inner sleeve 2, the driving member 4 and the operating member 5. Compared with the manual resetting method of inserting a new herbal product 9 into the inner sleeve 2, when replacing a new herbal product 9, the new herbal product 9 can be more stably loaded into the inner sleeve 2 and is not prone to breakage.

[0091] In this embodiment, it should be noted that in addition to the method of adding an elastic member 61 to achieve the automatic resetting of the inner sleeve 2, the driving member 4 and the operating member 5, in other optional embodiments, the inner sleeve 2, the driving member 4 and the operating member 5 can also be automatically reset by adding a permanent magnet, that is, the bottom plate portion 21 of the inner sleeve 2 is made of a magnetic conductive material, and the heating without burning device also includes a permanent magnet fixed in the main shell 1, and the permanent magnet is arranged below the bottom plate portion 21. The technical principle of this automatic resetting method and the technical effect that can be achieved are the same as those of the aforementioned embodiments (such as Figure 2-5 The embodiment shown in FIG. 1 is similar to the embodiment shown in FIG. 1 and will not be described in detail here.

[0092] Further, in some optional embodiments of the present invention, the driving member 4 can be rotatably mounted in the main housing 1 in the following manner, so that the driving member 4 can rotate under the action of the operating member 5 or the elastic member 61 or the inner sleeve 2:

[0093] For details, please refer to Figure 2-5 as well as Figure 8-11The heating without burning device also includes a rotating shaft 71 and a first rotating shaft bracket 81 and a second rotating shaft bracket 82 fixed in the main shell 1 at a relative interval. A rotating shaft hole 40 is opened on the driving member 4, wherein the rotating shaft 71 is rotatably matched with the rotating shaft hole 40, one end of the rotating shaft 71 is fixedly connected to the first rotating shaft bracket 81, and the other end is fixedly connected to the second rotating shaft bracket 82; or, the rotating shaft 71 is fixedly matched with the rotating shaft hole 40, one end of the rotating shaft 71 is rotatably connected to the first rotating shaft bracket 81, and the other end is rotatably connected to the second rotating shaft bracket 82.

[0094] For further information, please refer to Figure 2-5 as well as Figure 8-11 In some optional embodiments of the utility model, the bottom side wall of the inner sleeve 2 is provided with a notch 22 adapted to one end of the driving member 4, one end of the driving member 4 extends into the notch 22 and abuts against the inner wall of the notch 22, and the contact surface between the driving member 4 and the inner sleeve 2 is an arc surface (that is, the surface where the driving member 4 contacts the inner sleeve 2 is an arc surface, and the surface where the inner sleeve 2 contacts the driving member 4 is also an arc surface). This arrangement allows one end of the driving member 4 to smoothly abut against the outer wall of the inner sleeve 2, so that the driving member 4 can more stably drive the inner sleeve 2 to move upward or the inner sleeve 2 can more stably drive the driving member 4 to rotate to the initial position.

[0095] It should be noted that other contents of the heating without burning device disclosed in the present utility model can be found in the prior art and will not be described in detail here.

[0096] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
