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] Currently, electronic cigarettes on the market mainly fall into two categories: e-cigarettes that produce smoke by evaporating e-liquid and low-temperature cigarettes that produce smoke by heating / distilling tobacco materials at low temperatures (150-300 degrees Celsius). Compared with traditional cigarettes, e-cigarettes and low-temperature cigarettes operate at lower temperatures, and the smoke produced by the e-liquid or low-temperature cigarettes contains far fewer harmful components than that of traditional cigarettes. Therefore, using e-cigarettes or low-temperature cigarettes can greatly avoid the adverse effects of cigarettes on the human body.

[0003] With the widespread use of low-temperature cigarettes in overseas markets, low-temperature smoking devices have attracted much attention from consumers. After smoking, the tobacco tends to stick to the heating element when pulled out, requiring the secondary mechanism of the cover to remove it. This is because the tobacco is heated at high temperatures by the central heating element, causing the moisture in the tobacco to evaporate and shrink. At the same time, tar adheres to the heating element. Users rely on manually rotating the tobacco left and right to pull it out, but they often forget and simply pull it out directly, leaving the tobacco inside the device, causing inconvenience to customers. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a low-temperature smoking device that is easy to operate and effectively prevents tobacco from sticking to the heating element.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] A low-temperature smoking device, comprising:

[0007] The housing has a receiving cavity formed thereon for inserting tobacco products;

[0008] A heating element is disposed within the housing, with its heating end extending into the receiving cavity;

[0009] The low-temperature smoking device is characterized by further comprising:

[0010] A pressing element is disposed on the housing and is capable of moving the heating element relative to the receiving cavity from a first position to a second position;

[0011] An elastic element is connected between the pressing member and the housing so as to drive the pressing member and the heating element to reset when the pressing member is released;

[0012] A spring-loaded ball is connected to the heating element to lock it in a first position;

[0013] The housing is provided with a limiting groove that mates with the spring top ball;

[0014] When the heating element is in the first position, it is inserted into the tobacco product, and the spring top bead moves against the limiting groove; when the heating element is in the second position, it is withdrawn from the tobacco product, and the spring top bead separates from the limiting groove.

[0015] Furthermore, the receiving cavity has opposing first and second ends; wherein,

[0016] The first end is used to insert a tobacco product, and the second end is a closed end with a perforation, wherein the heating end of the heating element passes through the perforation.

[0017] Furthermore, the pressing element is a pressing sleeve that is slidably sleeved outside the receiving cavity and connected to the heating element, and the housing is provided with a guiding mechanism to guide the movement of the pressing sleeve.

[0018] Furthermore, the spring top balls are arranged in pairs on the side of the mounting base, and the limiting groove is provided on the guide sleeve.

[0019] Furthermore, the pressing sleeve and the receiving cavity are provided with a matching elastic buckle and a locking part. When the pressing sleeve is reset, the elastic buckle and the locking part move and abut against each other.

[0020] Furthermore, multiple elastic buckles are arranged along the circumferential direction of the cross-section of the receiving cavity.

[0021] Furthermore, the guiding mechanism is a guide sleeve coaxially mounted with the receiving cavity, the mounting seat of the heating element is movably disposed in the guide sleeve, the guide sleeve is provided with a guide groove parallel to the insertion direction of the tobacco product, and the mounting seat is provided with a guide block that matches and passes through the guide groove and connects to the pressing sleeve.

[0022] Furthermore, multiple guide grooves are arranged along the circumferential direction of the cross-section of the guide sleeve.

[0023] Furthermore, the housing includes a lower shell and a cigarette insert pipe installed on the top of the lower shell, the inner cavity of the cigarette insert pipe forming the receiving cavity, and the guide sleeve being fixedly installed at the bottom end of the cigarette insert pipe.

[0024] Furthermore, the guide sleeve is provided with a partition that closes the bottom end of the cigarette insertion tube, and the heating end of the heating element extends through the partition into the cigarette insertion tube.

[0025] Furthermore, the lower shell is provided with a power supply component for supplying power to the heating element.

[0026] Furthermore, the lower shell is also equipped with control buttons.

[0027] Compared with the prior art, the advantages of this invention are as follows: After the tobacco product such as the cigarette is finished smoking, pressing the pressing part moves the heating element along the insertion direction of the cigarette, causing the heating element to detach from the tobacco product. At this time, the tobacco product is pulled out, and the pressing part is released. The elastic element resets the pressing part and the heating element, which solves the problem of tobacco sticking. The operation is very convenient. At the same time, the spring top ball and the limiting groove between the heating element and the shell prevent the heating element from moving during the tobacco product process due to the locking of the spring top ball, thus not affecting the taste of the tobacco product.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] join Figures 1-3 A low-temperature smoking device includes a housing 1 and a heating element 2, a battery 3 and a PCB board 4 disposed within the housing 1. The battery 3 is connected to the PCB board 4, and the PCB board 4 is connected to the heating element 2, thereby forming a heating control circuit. A button 5 is also provided on the side of the housing 1. By pressing the button 5, the heating control circuit can be turned on and off, thereby controlling the power supply to the heating element 2.

[0038] See Figure 1 and Figure 2 In this embodiment, the top of the housing 1 of the low-temperature smoking device has a receiving cavity 7 for inserting the tobacco product 6. The tobacco product 6 can be a structure made of smoking material, such as a low-temperature cigarette stick or a cigarette cartridge. This embodiment uses a low-temperature cigarette stick as an example.

[0039] The receiving cavity has a first end and a second end; the first end is for inserting a tobacco product, and the second end is a closed end with a perforation, through which the heating end of the heating element extends into the receiving cavity. Specifically, in this example, the first end is the top opening of the receiving cavity. The heating element 2 is mounted inside the housing 1 at the bottom of the receiving cavity 7 via a mounting base 8. When the cigarette is inserted into the receiving cavity 7, the filter end of the cigarette protrudes outside the housing 1 for the user to hold and inhale, and also facilitates the removal of the cigarette. During the insertion of the cigarette, the heating end of the heating element 2 is inserted into the cigarette, heating the tobacco-generating material inside to produce smoke for the user to inhale. Airflow enters from the receiving cavity 7 and the side of the cigarette, passing through the bottom of the cigarette and carrying the smoke generated by the heated tobacco material from the top filter end of the cigarette to the user's mouth.

[0040] In this embodiment, the bottom end of the receiving cavity is designed as a closed end. This serves two purposes: firstly, it limits the insertion depth of the cigarette; secondly, it collects any tobacco or other residue that falls off after smoking. After the cigarette is removed, the residue can be easily poured out by tilting the device, preventing it from entering other parts of the device and making cleaning easier. It should be noted that the second end of the receiving cavity can also be designed as an open end, but this would result in the inability to limit the cigarette insertion depth and make cleaning the device more difficult.

[0041] See Figure 1 and Figure 2 The low-temperature smoking device also includes a pressing member 9 disposed in the housing 1 and capable of moving the heating element 2 relative to the receiving cavity 7 in the direction of insertion of the tobacco product 6, and an elastic element 10 connected between the mounting base 8 and the housing 1 to reset the pressing member 9 and the heating element 2 when the pressing member 9 is released. The heating element 2 can move relative to the receiving cavity 7 from a first position to a second position by the pressing member 9. When the heating element is in the first position, it is inserted into the tobacco product, and when it is in the second position, it is withdrawn from the tobacco product.

[0042] In this embodiment, the second end of the smoking device is designed as a closed end. When the heating element retracts, the cigarette cannot move synchronously with the heating element due to the restriction of the closed end wall of the receiving cavity, allowing the heating element to be smoothly withdrawn from the cigarette. However, when the second end is designed as an open end, if there is a large gap between the cigarette and the receiving cavity, and the frictional resistance is relatively small, the heating element may move the cigarette along with it during retraction, causing the heating element to be unable to withdraw from the cigarette. To solve this problem, the gap between the cigarette and the receiving cavity needs to be designed to be smaller to increase frictional resistance, but this makes it difficult to insert the cigarette into the receiving cavity.

[0043] See Figures 4-7 In this embodiment of the low-temperature smoking device, after the cigarette is finished, pressing the pressing part 9 moves the heating element 2 along the direction of cigarette insertion, causing the heating element 2 to detach from the cigarette. At this time, pulling out the cigarette can effectively prevent the tobacco from sticking to the heating element 2. After the cigarette is pulled out, releasing the pressing part 9 will reset the pressing part 9 and the heating element 2 under the elastic restoring force of the elastic element 10, and the user can then reinsert a new cigarette for smoking. The whole operation process is very convenient.

[0044] See Figure 1 and Figure 2 In the low-temperature smoking device with the above structure, when a cigarette is inserted for smoking, the heating element 2 mainly relies on the elastic element 10 for elastic support. If the downward pressure is greater than the supporting force of the elastic element 10, the heating element 2 will move along the direction of cigarette insertion during the insertion process, which will affect the smoking device's ability to heat the cigarette. To prevent the heating element 2 from moving backward during cigarette insertion, the low-temperature smoking device also includes a spring top bead 11 that locks the heating element 2 in the first position. The spring top bead 11 is set on the heating element 2, and a limiting groove 12 on the housing 1 is adapted to the spring top bead 11. When the heating element 2 is in the first position, the spring top bead 11 and the limiting groove 12 move against each other, thereby locking the heating element 2 in the first position. Here, it is necessary to adjust the resistance of the spring top bead 11 to be greater than the force required to insert the cigarette into the heating element 2.

[0045] When it is necessary to remove the cigarette, manually press the pressing part 9. As the pressing force increases, when the downward pressure is greater than the force of the side spring ball 11 and the central elastic element, the heating element and the mounting base move downward. The steel ball of the spring ball 11 retracts into the spring ball housing under the action of the pressing part 9, and then disengages from the limiting groove 12, thus unlocking. As the pressing continues, the heating element 2 moves downward under the action of the pressing part 9 and compresses the elastic element 10 until it is separated from the cigarette (heating element position 2). At this time, pulling out the cigarette can effectively prevent the tobacco from sticking to the heating element 2. After pulling out the cigarette, release the pressing part 9. The heating element 2 and the pressing part 9 move upward and reset under the elastic force of the elastic element 10. When the heating element 2 moves to the first position, the steel ball 1101 of the spring ball 11 extends out of the spring ball housing under the action of its internal spring and re-enters the limiting groove 12, locking the heating element 2 in the first position.

[0046] It should be noted that the cigarette can be configured as a two-section structure consisting of a tobacco section and a filter section, or as a two-section structure consisting of a tobacco section, a condenser section, and a filter section. Because the two-section structure cigarette has a condenser section, 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 structure cigarette.

[0047] See Figure 1 and Figure 2 In some embodiments, the housing 1 includes a lower housing 101 and a cigarette insert 102 mounted on the top of the lower housing 101. The inner cavity of the cigarette insert 102 directly forms the receiving cavity 7. The pressing member 9 is a pressing sleeve coaxially and slidably sleeved outside the cigarette insert 102. The bottom end of the pressing sleeve extends into the lower housing 101 and is fixedly connected to the mounting seat 8 inside the lower housing 101. The outer side of the pressing sleeve is also provided with a limiting step to limit its pressing motion. When the limiting step abuts against the top of the lower housing 101, it is the maximum pressing stroke of the pressing sleeve. The heating element 2 is fixedly mounted on the mounting seat 8. After the cigarette is finished, it can be operated with one hand. Pressing the pressing sleeve with the thumb moves the mounting seat 8 and the heating element 2 downward, causing the heating element 2 to detach from the cigarette and compress the elastic element 10. At this time, the cigarette can be pulled out, which can effectively solve the problem of tobacco sticking. Releasing the thumb, the mounting seat 8 moves the pressing sleeve and the heating element 2 upward and reset under the restoring force of the elastic element 10. It is conceivable that the elastic element 10 can be a helical spring, or it can be a rubber elastic element 10.

[0048] See Figure 8In some embodiments, a guide mechanism is also provided inside the housing to guide the movement direction of the pressing sleeve. Specifically, the guide mechanism is a guide sleeve 13 coaxially sleeved at the bottom end of the cigarette insertion tube 102. The guide sleeve 13 has a partition that closes the bottom end of the cigarette insertion tube 102. The partition has a through hole for the heating element to pass through. The guide sleeve 13 is fixedly installed in the lower shell 101 and has a guide groove 14 parallel to the cigarette insertion direction. The mounting base 8 is installed in the guide sleeve 13 and has a guide block 15 that matches and connects to the pressing sleeve through the guide groove 14. To ensure the reliability of the guidance, multiple guide grooves 14 are generally arranged along the circumference of the cross-section of the guide sleeve 13, such as two in this embodiment. Of course, the guide mechanism can also adopt other structures with guiding functions, such as guide rails, which will not be described in detail here.

[0049] See Figures 4-8 In this embodiment, a guide sleeve 13 is provided in the lower shell 101, which can guide the pressing direction of the pressing sleeve and effectively prevent the pressing sleeve from getting stuck during movement, causing pressing failure. After the thumb is released, the mounting base 8 drives the pressing sleeve and the heating element 2 to move upward and reset under the action of the reset force of the elastic element 10 until the mounting base 8 contacts the top of the guide sleeve 13. At this time, the heating end of the heating element 2 is inserted into the receiving cavity 7, and the user can start the next round of smoking.

[0050] To ensure the reliability of the locking mechanism, spring-loaded balls 11 are arranged in pairs on the side of the mounting base 8, and limiting grooves 12 are provided on the guide sleeve 13. In practical applications, the heating element 2 can be designed as a sheet or a rod. The sheet or rod heating element 2 can be configured as multiple heating sections with independent heating functions along the circumferential direction of the cross-section of the receiving cavity 7. This segmented heating avoids the situation where the same part of the tobacco product 6 is scorched due to prolonged heating, enhances the user's taste, improves the effective utilization rate of the tobacco product 6, and reduces waste.

[0051] In addition, a matching elastic buckle 16 and a locking part 17 can be provided between the pressing sleeve and the cigarette insert 102. Specifically, the elastic buckle 16 is provided on the inner wall of the pressing sleeve, and the locking part 17 is provided on the outer wall of the cigarette insert 102. When the pressing sleeve is reset, the elastic buckle 16 and the locking part 17 move and abut against each other, thereby increasing the movement damping force of the pressing sleeve. This ensures that the pressing sleeve can only be pushed when the pressing force increases to a certain level, effectively preventing accidental pressing caused by collision. Similarly, to ensure the reliability of locking, multiple elastic buckles 16 can be arranged along the circumferential direction of the pressing sleeve's cross-section.

[0052] The battery 3 can be a nickel-metal hydride battery, lithium-ion battery, or hydrogen battery. A charging interface 18 for charging the battery can also be set on the housing 1. A vibration motor 19 can also be set in the lower housing 101. When the charging interface 18 is connected to an external power source, the vibration motor vibrates to indicate charging information.

[0053] 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.
