Description
TECHNICAL FIELD
[0001] The present application relates to the tobacco technical field, in particular to a tobacco extraction clamping device and a heating appliance. BACKGROUND
[0002] With the diversification of tobacco industry products, the heat-not-burn product is favored by consumers because it is more similar to the traditional cigarette in terms of sensory taste. The product is used in combination with a heating appliance. The heat-not-burn cigarette is inserted into the heating cavity of the heating appliance, and the heating body heats the heat-not-burn cigarette in a low-temperature mode to generate aerosol for the consumer to smoke. The heating appliance has various heating forms such as an inner core and a periphery. The heat-not-burn cigarette is mainly made of tobacco sheet saturated with atomizing agent, and has a higher water content than the traditional cigarette. When the heating body is an inner core needle type, needle sticking is prone to occur during the smoking process of the heat-not-burn cigarette. The tobacco sheet falls into the heating cavity when the heat-not-burn cigarette is extracted, causing inconvenience in cleaning. When the heating body is a peripheral heating type, the heat-not-burn cigarette and the heating cavity are in a concentric cylindrical structure. A clamping structure is needed during smoking to prevent the heat-not-burn cigarette from being pulled out of the consumer's mouth.
[0003] The current method to avoid the above problems is to pull out the heating appliance part structure along with the heat-not-burn cigarette or to press the heat-not-burn cigarette containing tobacco. Both methods require certain training and operation redundancy for the consumer. The above steps are often ignored during the use of the product, resulting in the problem of difficult extraction of the heat-not-burn cigarette. CONTENT OF THE UTILITY MODEL
[0004] To solve the above technical problems, the purpose of the present utility model is to provide a tobacco extraction clamping device and a heating appliance which are convenient to operate.
[0005] The technical scheme provided by the present utility model is as follows:
[0006] A tobacco extraction clamping device for clamping a heat-not-burn cigarette in a heating appliance, comprising a cigarette accommodating cavity, an elastic mechanism, a clamping mechanism, and a linkage mechanism. The cigarette accommodating cavity is used to accommodate the heat-not-burn cigarette. The elastic mechanism is located below the cigarette accommodating cavity. The linkage mechanism connects the cigarette accommodating cavity and the clamping mechanism. When the heat-not-burn cigarette is inserted, the bottom of the heat-not-burn cigarette presses the cigarette accommodating cavity, causing the cigarette accommodating cavity to move downward. The elastic mechanism is compressed, and the cigarette accommodating cavity moves downward to drive the clamping mechanism to move through the linkage mechanism, thereby clamping the heat-not-burn cigarette. When the heat-not-burn cigarette is extracted, the elastic mechanism is reset to push the cigarette accommodating cavity to move upward through the linkage mechanism, thereby driving the clamping mechanism to move and release the heat-not-burn cigarette. The cigarette accommodating cavity holds the bottom of the heat-not-burn cigarette and pops up upward.
[0007] Preferably, the elastic mechanism is a tension spring fixed between the inner side of the bottom wall of the heat-not-burn cigarette clamping shell and the outer side of the bottom wall of the cigarette accommodating cavity.
[0008] Preferably, the clamping mechanism includes a first clamping member and a second clamping member respectively located on both sides of the cigarette and can only move laterally relative to each other. The first clamping member and the second clamping member are both provided with cigarette clamping protrusions for clamping the cigarette through the friction between the cigarette clamping protrusions and the cigarette.
[0009] Preferably, the first clamping member and the second clamping member are respectively provided with a first sliding guide rail and a second sliding guide rail, and the clamping mechanism further comprises a first fixed guide rail and a second fixed guide rail respectively cooperating with the first sliding guide rail and the second sliding guide rail so that the first clamping member and the second clamping member can only move laterally.
[0010] Preferably, the first clamping member and the second clamping member are respectively provided with a first sliding rack and a second sliding rack, and the cigarette holding and clamping device also includes a transmission gear and an active member, the active member is connected to the cigarette holding chamber, and is provided with a sliding tooth groove, the sliding tooth groove, the first sliding rack and the second sliding rack are all engaged with the transmission gear to form the linkage mechanism, so that when the cigarette holding chamber moves downward, the transmission gear is driven to rotate through the sliding tooth groove, and then the first sliding rack and the second sliding rack move inward relative to each other, so that the cigarette clamping protrusion contacts the cigarette, so as to clamp the cigarette through the friction between the cigarette clamping protrusion and the cigarette.
[0011] Preferably, the first sliding rack and the second sliding rack are arranged transversely, and the sliding tooth groove is arranged longitudinally.
[0012] Preferably, the active member further includes a third sliding guide rail, and the cigarette clamping device further includes a third fixed guide rail that cooperates with the third sliding guide rail to limit the longitudinal movement of the active member.
[0013] A heating device comprises a shell and a cigarette clamping device. The cigarette clamping device is the cigarette clamping device described above and is fixed in the shell. The heating needle is fixed on the shell and inserted into the cigarette accommodating cavity in the longitudinal direction.
[0014] Compared with the existing technology, the cigarette lifting and clamping device and heating appliance of the present invention, by providing a cigarette accommodating chamber, an elastic mechanism, a clamping mechanism, and a linkage mechanism, can adapt to the consumer's behavioral habits of inserting a cigarette when smoking and taking out the cigarette after smoking. It can complete the extraction and clamping of the cigarette by eliminating unnecessary redundant actions. It is easy to operate and can avoid problems such as tobacco falling and tobacco sticking to needles, which cause inconvenience in use and sensory discomfort. BRIEF DESCRIPTION OF THE DRAWINGS

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.
[0027] like Figures 1 to 5 As shown, an embodiment of the present invention provides a heating device, comprising a housing 11, a first clamping member 12, a second clamping member 13, a first fixed guide rail 14, a second fixed guide rail 15, a transmission gear 16, an active member 17, a third fixed guide rail 18, a fourth fixed guide rail 19, a heating needle 20, and a tension spring 21. The first clamping member 12, the second clamping member 13, the first fixed guide rail 14, the second fixed guide rail 15, the transmission gear 16, the active member 17, the third fixed guide rail 18, the fourth fixed guide rail 19, and the tension spring 21 form a cigarette holding and clamping device, which is fixed in the housing.
[0028] The first clamping member 12 includes a first sliding rack (unnumbered), a first sliding guide rail (unnumbered), and a cigarette-holding protrusion. The second clamping member 13 includes a second sliding rack 131, a second sliding guide rail 132, and a cigarette-holding protrusion 133. The first and second fixed guide rails 14, 15 respectively cooperate with the first and second sliding guide rails 132 to ensure that the first and second clamping members 12, 13 can only move laterally.
[0029] The active member 17 includes a sliding tooth groove 171, a third sliding guide rail 172 and a cigarette receiving cavity 173. The active member 17 is preferably made of a temperature-resistant material, such as PEEK (polyetheretherketone).
[0030] The extension spring 21 is used to press the cigarette receiving chamber 173 downward when a cigarette is inserted, and to return the extension spring 21 to push the cigarette receiving chamber 173 upward when a cigarette is removed. In other embodiments, the extension spring is not limited to other elastic mechanisms and may be other types of elastic mechanisms.
[0031] The sliding tooth grooves of the active member 17, the first sliding rack of the first clamping member 12, the second sliding rack 131 of the second clamping member 13, and the transmission gear 16 mesh together to form a linkage mechanism. Of course, in other embodiments, the linkage mechanism may also adopt other structures, so that when a cigarette is inserted, the bottom of the cigarette presses against the cigarette receiving chamber, causing the cigarette receiving chamber to move downward, and the linkage mechanism drives the clamping mechanism to move and clamp the cigarette; when the cigarette is removed, the elastic mechanism resets and pushes the cigarette receiving chamber upward, driving the clamping mechanism through the linkage mechanism to release the cigarette.
[0032] The third fixed guide rail 18 cooperates with the third sliding guide rail 172 to enable the active member 17 to move only longitudinally. The fourth fixed guide rail 19 cooperates with the corresponding sliding groove provided at the rear of the active member 17 to play a role in assisting sliding.
[0033] The heating needle 20 is fixed on the housing 11 and inserted into the cigarette receiving cavity 173 in the longitudinal direction.
[0034] During use, a cigarette is inserted, and its bottom touches the bottom of cigarette receiving chamber 173, pressing tension spring 21. This causes sliding tooth groove 171 to rotate transmission gear 16. This rotation of transmission gear 16 engages sliding rack 131, driving clamping member 12 to clamp the cigarette. Similarly, clamping member 13 clamps the cigarette. The further the cigarette is pressed downward, the greater the radial pressure exerted by clamping members 12 and 13. When the friction between the two points of clamping protrusion 133 and the weight of the cigarette is greater than or equal to the upward force of the spring, the cigarette is secured within cigarette receiving chamber 173. After puffing, when removing the cigarette, the upward force of tension spring 21 is increased. When the combined force of the pulling force and the tension of the spring exceeds the friction between the two points of clamping protrusion 133 and the weight of the cigarette, cigarette receiving chamber 173 cradles the bottom of the cigarette and springs upward, preventing the needle from sticking and tobacco from falling out.
[0035] If the friction coefficient between the cigarette pinching protrusion 133 and the cigarette surface is μ, the contact area is S, the tension coefficient of the tension spring 21 is k, the compression amount is x, the weight of the cigarette is f1, and the force of the consumer pulling the cigarette is f2, then the force relationship in this process must satisfy:
[0036] When the cigarette is clamped, f1+2μS≥kx;
[0037] When extracting a cigarette, f2+kx≥2μS+f1.
[0038] This relationship can be used to select the cigarette clamping bump structure and the tension spring.
[0039] In this embodiment, the cigarette clamping protrusions are two symmetrical points, which can be set to multiple points or surface contact to increase the contact area S, thereby increasing the friction between the cigarette and the protrusions.
[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
