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

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.

[0052] Please refer to Figures 1 to 6 The embodiment of the utility model provides a heat-not-burn device for heating and atomizing a herbal product 10 to generate an aerosol for a user to inhale. The heat-not-burn device comprises a main shell 1, a heating body 3, a driving member 5 rotatably mounted in the main shell 1, a push rod 6 slidably connected to the main shell 1, and an inner sleeve 2 movably mounted in the main shell 1, wherein:

[0053] 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 .

[0054] 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.

[0055] One end of the driving member 5 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 5 may abut or connect with the outer wall of the middle part of the inner sleeve 2, or may abut or connect with the bottom wall of the inner sleeve 2, or may abut or connect 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 6 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 also be noted 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.

[0056] One end of the push rod 6 is in close contact with the end of the driving member 5 away from the inner sleeve 2, and the other end of the push rod 6 is exposed to the side wall of the main housing 1. The push rod 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 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 6 Clockwise direction in the structure shown.

[0057] 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.

[0058] Based on the above structural design, the use principle of the heating without burning device provided in this embodiment is as follows:

[0059] 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;

[0060] like Figure 3-4 As shown, when the herbal product 10 becomes residual smoke after being heated and atomized and needs to be replaced, the user can apply a thrust to the end of the push rod 6 exposed on the side wall of the main shell 1 by pressing with his hand, so that the push rod 6 drives 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 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 upward movement of the inner sleeve 2, the bottom plate portion 21 of the inner sleeve 2 will push the residual smoke toward The inner sleeve 2 and the residual smoke as a whole move upward relative to the heating part 31, that is, the residual smoke and the heating part 31 of the heating body 3 will have relative movement, 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 10 can be loaded into the inner sleeve 2 and can continue to smoke. 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 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 3131 can be destroyed in advance, so that the user can easily remove all the residual smoke by hand later, and this embodiment does not impose specific restrictions on this.

[0061] In the present embodiment, it is understandable that after the residual cigarettes are taken out by pressing the push rod 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, the drive member 5 and the push rod 6. Optionally, in some usage scenarios, the inner sleeve 2, the drive member 5 and the push rod 6 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 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 5 to rotate along the second rotation direction. At the same time, the drive member 5 will drive the push rod 6 to slide until both the drive member 5 and the push rod 6 are 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 Counterclockwise in the structure shown.

[0062] 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 2-6 As 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.

[0063] Furthermore, in some optional embodiments of the present invention, the specific structural form of the driving member 5 can be as follows:

[0064] Please refer to Figure 2-4The push rod 6 is arranged horizontally, and the driving member 5 includes a driving part 51 and a force-bearing part 52 which are connected at an angle. The driving part 51 is arranged horizontally and one end of the driving part 51 away from the force-bearing part 52 abuts or is connected to the bottom outer wall of the inner sleeve 2. The force-bearing part 52 is arranged longitudinally and one end of the force-bearing part 52 away from the driving part 51 abuts or is connected to one end of the push rod 6. The connection between the driving part 51 and the force-bearing part 52 is rotatably arranged relative to the main shell 1. In this way, when the end of the push rod 6 away from the force-bearing part 52 is pressed by an external force, the push rod 6 will drive the force-bearing part 52 to rotate together with the driving part 51 as a whole along the first rotation direction (i.e., clockwise direction). During the rotation of the driving part 51, the end of the driving part 51 close to the inner sleeve 2 will push the inner sleeve 2 to move upward, so that the residual smoke can move upward with the inner sleeve 2 as a whole relative to the heating part 31, thereby destroying the adhesion between the residual smoke and the heating part 31, so that the user can easily remove all the residual smoke by hand later.

[0065] In this embodiment, it should be noted that the angle between the driving part 51 and the force-bearing part 52 can be an acute angle, a right angle, or an obtuse angle, as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this. It should also be noted that when one end of the push rod 6 is connected to the end of the driving member 5 away from the inner sleeve 2 (i.e., the end of the force-bearing part 52 away from the driving part 51), the connection method can be a snap connection, a threaded connection, a welding, etc., as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this.

[0066] Furthermore, please combine Figure 2-5 As shown, in some optional embodiments of the present invention, the bottom side wall of the inner sleeve 2 is provided with a notch 22 adapted to one end of the driving part 51, one end of the driving part 51 extends into the notch 22 and abuts against the inner wall of the notch 22, and the contact surface between the driving member 5 and the inner sleeve 2 is an arc surface (that is, the surface where the driving member 5 contacts the inner sleeve 2 is an arc surface, and the surface where the inner sleeve 2 contacts the driving member 5 is also an arc surface). This arrangement enables the end of the driving part 51 away from the force-bearing part 52 to smoothly maintain abutment with the outer wall of the inner sleeve 2, so that the driving member 5 can more stably drive the inner sleeve 2 to move upward or the inner sleeve 2 can more stably drive the driving member 5 to rotate to the initial position.

[0067] Furthermore, in order to facilitate the resetting of the inner sleeve 2, the driving member 5 and the push rod 6, in some optional embodiments of the utility model, the heating without burning device may be designed as follows:

[0068] For details, please refer to Figure 2-5The heating without burning device also includes an elastic member 71 for resetting the driving member 5 together with the push rod 6. The elastic member 71 is transversely arranged in the main shell 1, 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 end of the force-bearing portion 52 away from the driving portion 51. Exemplarily, one end of the elastic member 71 abuts against the side wall of the mounting portion 32, and the other end of the elastic member 71 abuts against the side of the force-bearing portion 52 facing away from the push rod 6. In this way, by adding the elastic member 71, when the user needs to break the adhesion between the residual smoke and the heating unit 31 and presses the end of the push rod 6 exposed on the side wall of the main shell 1, the force-bearing portion 52 will squeeze the elastic member 71 so that the elastic member 71 will be in a compressed state. Then, after the user removes the pressing force applied to the push rod 6, under the action of the elastic restoring force of the elastic member 71, the entire driving member 5 will rotate along the second rotation direction (i.e., counterclockwise) until it returns to the initial position. In the process of the driving member 5 rotating along the second rotation direction, the driving unit 5 The end connected to the inner sleeve 2 will drive the inner sleeve 2 to move downward to the initial position. At the same time, the force-bearing portion 52 will drive the push rod 6 to slide in the direction away from the mounting portion 32 to the initial position, thereby realizing the automatic reset of the inner sleeve 2, the driving member 5 and the push rod 6 without the need for the user to manually reset the inner sleeve 2, the driving member 5 and the push rod 6. Compared with the manual reset method of 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.

[0069] In this embodiment, it should be noted that, in specific implementation, the elastic member 71 can be a spring 711, a spring, 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 specific restrictions on this.

[0070] In this embodiment, it should be noted that the operation of manually removing the residual cigarettes can be performed before the user removes the pressing force applied to the push rod 6, or after the user removes the pressing force applied to the push rod 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 cigarettes is performed after the user removes the pressing force on the push rod 6, it is equivalent to two relative movements between the residual cigarettes and the heating part 31 before the residual cigarettes are removed, which is more conducive to destroying the adhesion between the residual cigarettes and the heating part 31, and is also conducive to saving the effort applied by the user to the push rod 6.

[0071] For further information, please refer to Figure 2-5In some optional embodiments of the present invention, the elastic member 71 includes a spring 711, and a transversely arranged positioning column 521 is arranged on the side of the force-bearing portion 52 facing away from the push rod 6, and the positioning column 521 extends into the spring 711, and one end of the spring 711 is fixed relative to the side of the force-bearing portion 52 facing away from the push rod 6, and the other end is fixed relative to the main housing 1. In this way, the positioning column 521 can play a certain positioning role on the spring 711, thereby improving the installation convenience of the spring 711 and allowing the spring 711 to elastically expand and contract more stably.

[0072] Furthermore, in order to facilitate the resetting of the inner sleeve 2, the driving member 5 and the push rod 6, in other optional embodiments of the utility model, the heating without burning device may also be designed as follows:

[0073] For details, please refer to Figure 6 The heating without burning device also includes an elastic member 71 for resetting the inner sleeve 2. The elastic member 71 is longitudinally arranged in the main shell 1, 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 sandwiched between the top of the upper cover 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 presses the end of the push rod 6 exposed to the side wall of the main shell 1, the top of the inner sleeve 2 will squeeze the elastic member 71 so that the elastic member 71 will be in a compressed state, and then after the user removes the pressing force applied to the push rod 6, the inner sleeve 2 will move downward to the initial position under the action of the elastic restoring force of the elastic member 71, wherein, during the downward movement of the inner sleeve 2, the inner sleeve 2 will drive the driving The driving member 5 rotates to the initial position, and at the same time, the force-bearing portion 52 of the driving member 5 drives the push rod 6 to return to the initial position, thereby realizing the automatic resetting of the inner sleeve 2, the driving member 5 and the push rod 6 without the need for the user to manually reset the inner sleeve 2, the driving member 5 and the push rod 6. Compared with the manual resetting method by inserting the new herbal product 10 into the inner sleeve 2, when replacing the new herbal product 10, the new herbal product 10 can be more stably loaded into the inner sleeve 2 without being easily broken.

[0074] In this embodiment, it can be understood that the main difference between the automatic reset solution of this embodiment and the automatic reset solution of the embodiment shown in the figure is that the specific arrangement position of the elastic member 71 is different.

[0075] Furthermore, in order to facilitate the resetting of the inner sleeve 2, the driving member 5 and the push rod 6, in some optional embodiments of the utility model, the heating without burning device can also be designed as follows:

[0076] For details, please refer to Figure 2-5The bottom plate 21 is made of a magnetic material (such as iron, nickel-chromium-iron alloy, silicon steel and other magnetic materials). The heating without burning device also includes a permanent magnet 72 (such as a magnet) fixed in the main shell 1. The permanent magnet 72 is located below the bottom plate 21. In this way, after the user removes the pressing force applied to the push rod 6, the attraction of the permanent magnet 72 to the bottom plate 21 can be used to drive the inner sleeve 2 to move downward to the initial position, wherein, during the downward movement of the inner sleeve 2, the inner sleeve 2 will drive the driving member 5 to rotate to the initial position. At the same time, the force-bearing portion 52 of the driving member 5 will drive the push rod 6 to return to the initial position, thereby realizing automatic resetting of the inner sleeve 2, the driving member 5 and the push rod 6 without the user having to manually reset the inner sleeve 2, the driving member 5 and the push rod 6. 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.

[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, the driving member 5 can be rotatably mounted in the main housing 1 in the following manner, so that the driving member 5 can rotate under the action of the push rod 6 or the inner sleeve 2:

[0079] For details, please refer to Figure 2-5 The heating without burning device further comprises a rotating shaft 4 and a first rotating shaft bracket 81 and a second rotating shaft bracket 82 fixed in the main housing 1 at a relatively interval, and a rotating shaft hole 50 is opened on the driving member 5, wherein:

[0080] The rotating shaft 4 is rotatably matched with the driving member 5 through the rotating shaft hole 50 (specifically, the rotating shaft 4 is clearance-matched with the connection between the driving part 51 and the force-bearing part 52 through the rotating shaft hole 50), and one end of the rotating shaft 4 is fixedly connected to the first rotating shaft bracket 81, and the other end is fixedly connected to the second rotating shaft bracket 82;

[0081] Alternatively, the rotating shaft 4 is fixedly fitted with the driving member 5 through the rotating shaft hole 50 (specifically, the rotating shaft 4 is interference fit at the connection between the driving part 51 and the force-bearing part 52 through the rotating shaft hole 50), and one end of the rotating shaft 4 is rotatably connected to the first rotating shaft bracket 81, and the other end is rotatably connected to the second rotating shaft bracket 82.

[0082] For further information, please refer to Figure 2-4 as well as Figure 6In some optional embodiments of the utility model, the heating without combustion device also includes a battery 91, a control circuit board 92 and a switch button 93. The battery 91 and the control circuit board 92 are both installed in the main shell 1, and the switch button 93 is exposed on the side wall of the main shell 1. The control circuit board 92 is electrically connected to the battery 91, the switch button 93, and the heating part 31 respectively. The control circuit board 92 can control the operation of the heating part 31 of the heating body 3 according to the signal triggered by the switch button 93, thereby realizing the intelligence of the heating without combustion device. Specifically, when the user needs to use the heat-not-burn device for smoking, the herbal product 10 to be heated can be loaded into the accommodating cavity 20 of the inner sleeve 2, so that the heating part 31 of the heating body 3 located in the accommodating cavity 20 is inserted into the interior of the herbal product 10, and then the user can trigger the control circuit board 92 to control the heating part 31 to power on by pressing the switch button 93. The heating part 31 is powered on and generates heat to heat and atomize the herbal product 10, thereby generating an aerosol for the user to inhale. After the user has finished smoking, the user can continue to trigger the control circuit board 92 to control the heating part 31 to power off and stop working by pressing the switch button 93, and then the operation of removing the residual smoke can be performed.
