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

[0052] 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.

[0053] Please refer to Figures 1 to 7 The embodiment of the utility model provides a heat-not-burn device for heating and atomizing a herbal product to produce an aerosol for users to inhale. The heat-not-burn device includes a main housing 1, a heating body 3, a rotating shaft 4, a driving member 5, a knob 6, and an inner sleeve 2 movably mounted in the main housing 1, wherein:

[0054] The inner sleeve 2 is provided with a receiving cavity 20 for receiving the herbal product 10 , and the bottom of the inner sleeve 2 has a bottom plate portion 21 for supporting the herbal product 10 .

[0055] 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.

[0056] The rotating shaft 4 is at least partially located in the main housing 1 , and both ends of the rotating shaft 4 are rotatably arranged relative to the main housing 1 .

[0057] The driving member 5 is located in the main housing 1 and is fixedly sleeved on the rotating shaft 4 (specifically, a rotating shaft hole 50 is opened on the driving member 5, and the rotating shaft 4 is fixedly matched with the driving member 5 through the rotating shaft hole 50), and one end of the driving member 5 is in close contact with the outer wall of the inner sleeve 2. It should be noted here that in the specific implementation, the driving member 5 can abut or connect with the middle outer wall of the inner sleeve 2, or abut or connect with the bottom wall of the inner sleeve 2, or abut or connect with the bottom outer wall 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 6-7 As shown, the driving member 5 abuts against the bottom outer wall of the inner sleeve 2. Specifically, the driving member 5 abuts against the bottom outer side wall of the inner sleeve 2. It should also be noted that when the driving member 5 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.

[0058] The knob 6 is fixedly connected to one end of the rotating shaft 4 and exposed on the side wall of the main housing 1. The knob 6 is used to drive the driving member 5 to rotate along the first rotation direction to drive the inner sleeve 2 to move relative to the heating portion 31 of the heating body 3 in a direction away from the mounting portion 32 of the heating body 3. It can be understood here that, for example, the first rotation direction is as follows: Figure 2-4 as well as Figure 6-7 Clockwise direction in the structure shown.

[0059] In this embodiment, it should be noted that the above-mentioned herbal product 10 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, 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 low-temperature non-burning cigarette 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 10 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 10 as a low-temperature non-burning cigarette as an example.

[0060] In this embodiment, based on the above structural design, the use principle of the heating without burning device provided in this embodiment is as follows:

[0061] like Figure 2-3 As shown, when the user needs to use the heat-not-burn device for inhalation, the herbal product 10 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 10, and the bottom of the herbal product 10 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 10, thereby generating an aerosol that can be inhaled by the user;

[0062] Combination Figure 1 as well as Figure 3-4As shown, when the herbal product 10 becomes residual smoke after being heated and atomized and needs to be replaced, the user can turn the knob 6 by hand to rotate the rotating shaft 4 along the first rotation direction, thereby driving the driving member 5 to rotate along the first rotation direction. During the rotation of the driving member 5 along the first rotation direction, the inner sleeve 2 together with the residual smoke as a whole will be driven to move relative to the heating portion 31 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 upward movement of the inner sleeve 2, the bottom plate portion 21 of the inner sleeve 2 will push The residual smoke moves upward, causing the inner sleeve 2 and the residual smoke as a whole to move relative to the heating part 31 in a direction away from the mounting part 32. That is, relative movement occurs between the residual smoke and the heating part 31 of the heating body 3, thereby destroying the adhesion between the residual smoke and the heating part 31 in advance, so that the user can easily take out all the residual smoke by hand later. After taking out all the residual smoke, the new herbal product 10 can be loaded into the inner sleeve 2 for continued smoking. That is, in the process of replacing the herbal product 10, the risk of residual smoke remaining on the heating body 3 can be effectively reduced, thereby avoiding adverse effects on the user's next use. It should be noted here that, in a specific implementation, the distance of relative movement between the residual smoke and the heating part 31 of the heating body 3 (i.e., 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 any specific restrictions on this.

[0063] In the present embodiment, it is understandable that after the residual cigarettes are taken out by turning the knob 6, in order to ensure that the subsequent residual cigarettes can be easily taken out again during subsequent use, it is usually necessary to reset the inner sleeve 2 and the drive member 5. Optionally, in some usage scenarios, the inner sleeve 2 and the drive member 5 can be reset by manual operation. Specifically, in the process of inserting a new herbal product 10 into the inner sleeve 2, the bottom of the herbal product 10 will push down the bottom plate portion 21 of the inner sleeve 2, causing the inner sleeve 2 to move downward and reset to the initial position. In the process of the inner sleeve 2 moving downward, the inner sleeve 2 will drive the drive member 5 to rotate in the second rotation direction until the drive member 5 is reset to the initial position. It is understandable here that the second rotation direction is opposite to the first rotation direction. The second rotation direction is as follows: Figure 2-4 as well as Figure 6-7 Counterclockwise in the structure shown.

[0064] 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 2-7As shown, the heating without burning device also includes an inner bracket 83, and the main shell 1 can specifically include a main shell 11 and an upper cover body 12. The lower end of the upper cover body 12 can be detachably connected to the upper end of the main shell 11 by means of threaded connection, plug-in, etc., and a socket 120 is provided on the upper cover body 12 for inserting the herbal product 10 into the accommodating cavity 20 of the inner sleeve 2. Specifically, the socket 120 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 12 through the inner bracket 83. Specifically, the inner bracket 83 is fixedly connected to the upper cover body 12, and the inner sleeve 2 is movably mounted on the inner bracket 83 by means of clearance fit, etc.; the mounting portion 32 of the heating body 3 is fixedly connected to the main shell 11.

[0065] Furthermore, in some optional embodiments of the present invention, the structure of the driving member 5 may be as follows:

[0066] Please refer to Figure 1-5 as well as Figure 7 The driving member 5 includes a cam 51, one end of which abuts against the outer wall of the inner sleeve 2, and the other end of the cam 51 is fixedly sleeved on the rotating shaft 4. In this way, when the knob 6 is subjected to the screwing force of the user and drives the cam 51 to rotate in the clockwise direction, the end of the cam 51 close to the inner sleeve 2 will push the inner sleeve 2 to move upward, so that the residual smoke can move upward relative to the heating part 31 along with the inner sleeve 2 as a whole, so that the adhesion between the residual smoke and the heating part 31 can be destroyed, so that the user can easily remove all the residual smoke by hand later.

[0067] Furthermore, please combine Figure 2-5 As shown, 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 cam 51, one end of the cam 51 extends into the notch 22 and abuts against the inner wall of the notch 22, and the contact surface between the cam 51 and the inner sleeve 2 is an arc surface (that is, the surface where the cam 51 contacts the inner sleeve 2 is an arc surface, and the surface where the inner sleeve 2 contacts the cam 51 is also an arc surface). This arrangement allows one end of the cam 51 to smoothly abut against the outer wall of the inner sleeve 2, so that the cam 51 can more stably drive the inner sleeve 2 to move upward or the inner sleeve 2 can more stably drive the cam 51 to rotate to the initial position.

[0068] Furthermore, in some other optional embodiments of the present invention, the structure of the driving member 5 may also be as follows:

[0069] Please refer to Figure 1 and Figure 6The driving member 5 includes a gear 52, which is fixedly sleeved on the rotating shaft 4. Accordingly, the outer wall of the inner sleeve 2 is provided with a rack portion 23, which moves in the same direction as the movement direction of the inner sleeve 2 (i.e., Figure 6 The inner sleeve 2 is provided with a rack portion 23 and a gear 52. The rack portion 23 is provided in an upward and downward direction (in the vertical direction shown in the figure, or the height direction of the heat-not-burn device, or the axial direction of the inner sleeve 2), and the rack portion 23 is meshed with the gear 52. In this way, when the knob 6 is subjected to the screwing force of the user and drives the gear 52 to rotate in the clockwise direction, the gear 52 pushes the rack portion 23 and causes the entire inner sleeve 2 to move upward, 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.

[0070] For further information, please refer to Figure 1 and Figure 5 In some optional embodiments of the present invention, the knob 6 is provided with anti-skid lines 61 on its circumferential sidewall. Such a configuration can increase the friction between the user's hand and the knob 6 when the user turns the knob 6, thereby facilitating the user to turn the knob 6 with less effort. It should be noted that in the specific implementation, the structural form of the anti-skid lines 61 can be at least one of a groove and a protrusion, as long as it can meet the use requirements. This embodiment does not impose any specific restrictions on the specific structural form of the anti-skid lines 61.

[0071] Furthermore, in order to facilitate the resetting of the inner sleeve 2 and the driving member 5, in some optional embodiments of the utility model, the heating without burning device may also be designed as follows:

[0072] For details, please refer to Figure 1-6 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 72 (such as a magnet) fixed in the main shell 1, and the permanent magnet 72 is arranged below the bottom plate portion 21. In this way, after the user removes the screwing force applied to the knob 6, the attraction of the permanent magnet 72 to the bottom plate portion 21 can be used to drive the inner sleeve 2 to move downward to the initial position, wherein, in the process of the inner sleeve 2 moving downward, the inner sleeve 2 will drive the driving member 5 to rotate to the initial position, thereby realizing automatic resetting of the inner sleeve 2 and the driving member 5 without the user manually resetting the inner sleeve 2 and the driving member 5. Compared with the manual resetting method by inserting a new herbal product 10 into the inner sleeve 2, when replacing a new herbal product 10, the new herbal product 10 can be more stably loaded into the inner sleeve 2 and is not prone to breakage.

[0073] In this embodiment, it should be noted that the operation of manually removing the residual smoke can be performed before the user removes the screwing force applied to the knob 6, or after the user removes the screwing force applied to the knob 6. 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 screwing force applied to the knob 6, 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 knob 6.

[0074] Furthermore, in order to facilitate the resetting of the inner sleeve 2 and the driving member 5, in other optional embodiments of the utility model, the heating without burning device may also be designed as follows:

[0075] For details, please refer to Figure 1 and Figure 7 The heating without burning device further comprises an elastic member 71 for resetting the inner sleeve 2. The elastic member 71 is arranged in the main housing 1. The elastic member 71 moves in the same direction as the movement direction of the inner sleeve 2 (i.e., Figure 7 The elastic member 71 is extended in the up and down directions shown, or the height direction of the heating without burning device, or the axial direction of the inner sleeve 2), and one end of the elastic member 71 is fixed relative to the main shell 1, and the other end of the elastic member 71 is fixed relative to the inner sleeve 2. Exemplarily, the elastic member 71 is clamped between the top of the upper cover body 12 and the top of the inner sleeve 2. In this way, by adding the elastic member 71, when the user needs to break the adhesion between the residual smoke and the heating part 31 and turns the knob 6, the elastic member 71 will be in a compressed state, and then after the user removes the twisting force applied to the knob 6, under the action of the elastic restoring force of the elastic member 71, the inner sleeve 2 will move downward to the initial position, wherein, in the process of the inner sleeve 2 moving downward, the inner sleeve 2 will drive the driving member 5 to rotate to the initial position, thereby realizing automatic resetting of the inner sleeve 2 and the driving member 5 without the user manually resetting the inner sleeve 2 and the driving member 5. Compared with the manual resetting method by inserting a new herbal product 10 into the inner sleeve 2, when replacing a new herbal product 10, the new herbal product 10 can be more stably loaded into the inner sleeve 2 and is not prone to breakage.

[0076] In this embodiment, it should be noted that, in specific implementation, the elastic member 71 may 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.

[0077] It should be noted here that, in specific implementation, the reset method of adding an elastic member 71 and the reset method of adding a permanent magnet 72 can be used either alone or simultaneously, depending on actual needs, and this embodiment does not impose any specific restrictions on this.

[0078] Further, in some optional embodiments of the present invention, at least part of the rotating shaft 4 can be installed in the main housing 1 and both ends of the rotating shaft 4 can rotate relative to the main housing 1 in the following manner, so that the driving member 5 can rotate under the action of the knob 6 or the inner sleeve 2:
