Description

Technical Field

[0001] This invention belongs to the field of smoking products technology, and in particular relates to a low-temperature smoking device. Background Technology

[0002] Low-temperature heated cigarette devices, as a new type of tobacco appliance, are handheld devices that effectively reduce harmful substances by heating tobacco at low temperatures, replacing traditional tobacco. In this field, a large proportion of tobacco appliances use a heating element inserted into the cigarette during heating. After heating, the tobacco material shrinks and adheres to the heating element due to carbonization. When removing the used cigarette, the cavity containing the inserted cigarette needs to be displaced to ensure complete separation of the cigarette from the heating element. This design concept is reflected in patents such as CN2018105522152, CN201821351564X, CN2018104394091, and CN2018219053343. However, these patents generally use electric control to separate the heating element from the cigarette, which involves energy consumption. Even some patents use purely mechanical methods to control the separation of the heating element and the cigarette, but these methods suffer from complex structures, inconvenient operation, and the inability to guarantee the locking position of the heating element. Summary of the Invention

[0003] This application aims to at least solve one of the existing technical problems. Therefore, one objective of the embodiments of the present invention is to provide a low-temperature smoking device that not only has a simple structure but also ensures that there are relatively few residues adhering to the heating element after the smoke dissipates.

[0004] To solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions:

[0005] The casing has an internal cavity for holding the cigarette.

[0006] A heating element is disposed within the receiving cavity to heat the cigarette;

[0007] The smoke-reducing assembly is capable of moving the heating element relative to the receiving cavity between a first position and a second position; wherein,

[0008] When the heating element is in the first position, the heating element is inserted into the cigarette; when the heating element is in the second position, the heating element is withdrawn from the cigarette.

[0009] The smoke-reducing assembly includes a slider that is slidably mounted in a groove in the housing and connected to the heating element, and an elastic element connected between the groove and the slider.

[0010] Furthermore, the extension direction of the groove is parallel to the insertion direction of the cigarette.

[0011] Furthermore, the slider is provided with an annular track groove parallel to the slide groove, one end of the connecting rod is rotatably connected to the housing, and the other end is provided with a sliding pin. The sliding pin is inserted into the annular track groove to force the connecting rod to move along the track of the annular track groove.

[0012] The annular track groove is composed of a first arc segment, a second arc segment, a third arc segment, and a fourth arc segment that are connected smoothly in sequence. The first arc segment and the third arc segment are arranged opposite each other and their protruding direction is towards the heating element.

[0013] Furthermore, the end of the housing away from the receiving cavity is also provided with a pressing button that drives the slider to move.

[0014] Furthermore, the elastic element is disposed at one end of the slider near the receiving cavity.

[0015] Furthermore, the receiving cavity has a first end and a second end opposite to each other; wherein the first end is for inserting a cigarette, and the second end is a closed end with a perforation, and the heating element is inserted into the receiving cavity through the perforation.

[0016] Furthermore, the housing also contains a battery that powers the heating element.

[0017] Furthermore, the elastic element is a spring.

[0018] Furthermore, the heating element is securely connected to the slider via a bracket.

[0019] Furthermore, the heating element is a heating rod or a heating plate.

[0020] Furthermore, the width of the annular track groove is greater than the diameter of the sliding pin.

[0021] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: When it is necessary to remove the cigarette, the present invention uses a sliding slider to drive the heating element out of the cigarette. At this time, pulling out the cigarette can effectively solve the problem of the smoking material sticking to the heating element, reduce the burden of cleaning the heating element, and effectively prevent the smoking material from falling into the smoking device. In addition, after the cigarette is pulled out, the slider is released, and the heating element is reset under the elastic force of the elastic element. The operation is convenient and the structure is simple. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] See Figures 1-4 A low-temperature smoking device includes a housing 1, a battery 2, a circuit board 3, and a heating element 4. The housing 1 has an internal cavity 5 for inserting a cigarette. The heating element 4 is disposed within the cavity 5 to heat the smoke-generating material in the cigarette, producing smoke for the user to inhale. The housing 1 also has a smoke-removing assembly capable of moving the heating element 4. The heating element 4 moves relative to the cavity 5 between a first position and a second position via the smoke-removing assembly. When the heating element 4 is in the first position, it is inserted into the cigarette; when it is in the second position, it is withdrawn from the cigarette.

[0034] Specifically, the smoke removal assembly includes a slider 6 and an elastic element 7. The slider 6 is slidably mounted in a groove 8 on the housing 1 and connected to the heating element 4. The elastic element 7 is connected between the groove 8 and the slider 6. The extension direction of the groove 8 is parallel to the movement direction of the heating element 4.

[0035] When the user needs to inhale, the cigarette is inserted into the receiving cavity 5 through the top opening of the receiving cavity 5. At the same time, the heating element 4 is inserted into the cigarette. The user inhales by holding the mouthpiece of the cigarette that protrudes outside the housing 1. Under the action of suction negative pressure, the external airflow enters the cigarette through the air intake gap between the cigarette and the side of the receiving cavity 5, bringing the smoke generated by the heating material to the user's mouth.

[0036] When you finish smoking and need to remove the cigarette, first slide the slider 6 to remove the heating element 4 from the cigarette, then pull the cigarette out of the receiving cavity 5 to complete the removal of the cigarette. The above method of removing the cigarette can effectively solve the problem of the smoking material sticking to the heating element 4, reduce the burden of cleaning the heating element 4, and effectively prevent the smoking material from falling into the smoking device. In addition, after the cigarette is pulled out, by releasing the slider 6, the heating element 4 is reset under the elastic force of the elastic element 7, and the user can reinsert a new cigarette.

[0037] Specifically, the battery 2, circuit board 3, and heating element 4 are all housed in the casing 1. The circuit board 3, battery 2, and heating element 4 are electrically connected to form a heating control circuit. A button 17 for human-machine interaction can also be provided on the side of the casing 1. The battery 2 can be a nickel-metal hydride battery 2, a lithium-ion battery 2, etc. When the battery 2 is a rechargeable battery 2, a charging interface also needs to be provided on the casing.

[0038] Understandably, in practical applications, the elastic element 7 can be a spring or a rubber component. And to facilitate the insertion of the heating element 4 into the cigarette, the heating element 4 can be designed as a rod or a sheet.

[0039] See Figure 1 and Figure 2 To prevent the cigarette from swinging left and right inside the receiving cavity 5 after it is inserted, the size of the cigarette 14 is designed to fit the receiving cavity 5. In addition, to facilitate uniform heating of the cigarette 14, the heating element is aligned with the axis of the receiving cavity. This ensures that the heating element is inserted at the center of the cigarette, allowing the heat generated by the heating element to be evenly distributed from the center of the cigarette to the circumference, thus ensuring the roasted taste.

[0040] See Figure 1 and Figure 2 In some embodiments, the receiving cavity 5 may be designed to have a first end and a second end opposite to each other; wherein the first end is an open end for inserting a cigarette, and the second end is a closed end with a perforation 9 through which the heating element 4 is inserted into the receiving cavity 5.

[0041] In this embodiment, the second end of the receiving cavity 5 is a closed end. The cigarette is inserted from the first end until it abuts against the second end, which means that the cigarette is fully inserted. This allows for convenient limitation of the insertion depth of the cigarette. In particular, when the perforation 9 is adapted to the heating element 4, during the movement of the heating element 4, the perforation 9 adapted to the heating element 4 can scrape off the residue adhering to the heating element 4 and retain it in the receiving cavity 5. Compared with directly pulling out the cigarette, this further reduces the residue on the heating element 4. Furthermore, after the cigarette is pulled out, the residue can be cleaned out of the smoking device by emptying the receiving cavity 5, reducing the number of times the smoking device needs to be cleaned.

[0042] See Figure 1 and Figure 5 In the above embodiment, since the heating element 4 is supported by the elastic force provided by the elastic element 7, if the rigidity of the elastic element 7 is insufficient during the cigarette insertion process, the heating element 4 may move along the cigarette insertion direction.

[0043] To address the aforementioned issues, this embodiment provides an annular track groove 10 parallel to the slide groove 8 on the slider 6. One end of the connecting rod 11 is rotatably connected to the housing 1 via a rotating shaft, and the other end is provided with a sliding pin 12. The sliding pin 12 is inserted into the annular track groove 10, and during the movement of the slider 6, it forces the end of the connecting rod 11 with the pin to move along the track of the annular track groove 10. The annular track groove 10 is composed of a first arc segment 101, a second arc segment 102, a third arc segment 103, and a fourth arc segment 104 connected smoothly in sequence. The third arc segment 103 and the first arc segment 101 are arranged vertically opposite each other and their protruding directions are both towards the heating element 4. The heating element 4 is fastened to the slider via a heating element bracket 15 using screws.

[0044] See Figures 6-10 In this embodiment, the slider 6 is provided with a specific annular track groove 10, see [link / reference] Figure 6 When slider 6 moves in the groove 8, it drives sliding pin 12 to slide along the annular track groove 10. Correspondingly, connecting rod 11 rotates relative to housing 1 around its axis. When sliding pin 12 slides to the middle (position A) of the third arc segment 103 driven by slider 6, slider 6 is released. Under the compressive rebound force of elastic element 7, slider 6 presses sliding pin 12 against position A of the track groove. Correspondingly, heating element 4 is in the first position. At this time, slider 6 cannot move downwards due to the restriction of sliding pin 12 on connecting rod 11, and is in a completely constrained and stable state in space. That is, heating element 4 cannot move downwards. When the cigarette is inserted into the receiving cavity 5, heating element 4 can be inserted into the cigarette and will not retract. When smoking is finished and the cigarette needs to be removed, slider 6 is pushed upwards. Figure 7 and Figure 8As shown, the sliding pin 12 of the connecting rod 11 will be displaced to the transition position (position B) between the third arc segment 103 and the fourth arc segment 104. After releasing the slider 6, under the action of the compressive rebound force of the elastic element 7, the slider 6 will move horizontally, and the sliding pin 12 of the connecting rod 11 will continue to slide along the trajectory of the annular track groove 10 until the sliding pin 12 of the connecting rod 11 reaches the middle of the first arc segment 101 (position C). Under the action of the compressive rebound force of the elastic element 7, the sliding pin 12 will press tightly against the upper side wall of the annular track groove 10, so that the slider 6 is in a completely constrained and stable state in space. The slider 6 will also drive the heating element support 15 and the heating element 4 to move to the second position. At this time, the heating element 4 will retract from the cigarette, and most of the area of ​​the heating element 4 will not be in contact with the cigarette, so the cigarette can be completely removed. See Figure 9 and Figure 10 When the sliding pin 12 of the connecting rod 11 reaches point D within the annular track groove 10, it continues to slide to point E (the transition point between the first arc segment 101 and the second arc segment 102), releasing the slider 6. Under the action of the compressive rebound restoring force of the elastic element 7, the slider 6 drives the sliding pin 12 of the connecting rod 11 to point A within the groove of the slider 6, thus placing the slider 6 in a fully constrained and stable state in space. (See also...) Figure 1 The slider 6 drives the heating element 4 to reset and return to the first position, ensuring that it can start working again when the next cigarette is inserted.

[0045] Specifically, to facilitate the operation of the slider 6, a pressing button 13 is provided at the end of the housing 1 away from the receiving cavity 5 to drive the slider 6 to move. The elastic element 7 is provided at the end of the slider 6 close to the receiving cavity 5. In this embodiment, by pressing the pressing button 13, the slider 6 can be driven to move toward the receiving cavity 5. In addition, to facilitate the movement of the sliding pin 12 along the trajectory line of the annular track groove 10, the width of the annular track groove 10 is greater than the diameter of the sliding pin 12.

[0046] To facilitate pressing operation, the end of the pressing button 13 away from the slider 6 extends outside the housing, and when the heating element is in the first position, the pressing button 13 is completely housed in the housing 1 to ensure the aesthetics of the smoking device. To prevent heat from being transferred towards the battery, a partition 17 is provided inside the housing 1 between the battery 2 and the heating element 4.

[0047] Specifically, a slider fixing shell is provided inside the housing 1. The slider fixing shell is composed of a left half shell A and a right half shell B connected by a snap fastener. The left half shell A and the right half shell B form a sliding groove for the slider 6 to slide linearly. One end of the elastic element 7 is embedded in the cylindrical end of the slider 6, and the other end contacts the left half shell A. Through its elastic force, the slider 6 is in a stable constrained state in a space without force. The other end of the slider 6 protrudes through the left half shell A and is tightly fitted with the pressing button 13. At the position of the pressing button 13, one end of the housing 1 is provided with a through hole with the same cross section as the pressing button 13 but with a clearance fit, ensuring that the user can contact the pressing button 13. One end of the connecting rod 11 is connected to the left half shell A through the rotating shaft 16, and the sliding pin of the other end is placed in the annular track groove 10 of the slider 6.

[0048] See Figure 1 and Figure 3 The housing 1 consists of a lower housing 101 with an opening at the top and a top cover 102 covering the lower housing 101. A cigarette insert is formed on the top cover for inserting a cigarette stick. The cigarette stick 14 is inserted into the receiving cavity through the cigarette insert and can be removed from the cigarette insert.

[0049] This embodiment has a hole on the cigarette holder housing for inserting a cigarette stick, and a space coaxial with the hole for accommodating the inserted cigarette stick. This space has a heating element that can be heated and can be displaced in space under certain conditions. After the cigarette stick is inserted into the space, the heating element is located in the internal space of the portion of the cigarette stick that can be heated. The part providing this space is located around the cigarette stick and is in a firm constrained state in the space. In any state of use or non-use, the space formed by this part and other parts that are connected and constrained with it are in a relatively static state and will not have relative positional displacement.

[0050] In this embodiment, the heating element of the smoking device is in a constrained and stationary state within the entire internal space of the device during the process of inserting a cigarette and heating and baking it. After the heating and baking is completed, the constraint is released, and the heating element is spatially displaced, thereby detaching from the tobacco.

[0051] The spatial displacement of the heating element under specific conditions in this embodiment is achieved through a device exposed outside the product casing. This device is connected and constrained to other parts through a certain feature to ensure the spatial constraint of the heating element. At a specific moment, such as when heating and baking are completed, by contacting it and applying a certain force, the heating element can be removed from the cigarette or restored to a state where it can contact the cigarette and work again.

[0052] It should be noted that the cigarette 14 can be configured as a two-section structure consisting of a tobacco section and a filter section, or as a three-section structure consisting of a tobacco section, a condenser section, and a filter section. The three-section cigarette has a condenser section, so the temperature of the smoke entering the user's mouth can be effectively reduced, resulting in a better smoking experience compared to the two-section cigarette.

[0053] In practical applications, the sheet-shaped or rod-shaped heating element can be configured into multiple heating sections with independent heating functions along the circumferential direction of the cross-section of the receiving cavity 5. This segmented heating avoids the situation where the same part of the tobacco product is scorched due to prolonged heating, enhances the user's taste, improves the effective utilization rate of tobacco products, and reduces waste.

[0054] The above embodiments are merely illustrative examples to clearly illustrate the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
