The specific meaning of the above terms in the present disclosure can be understood by those skilled in the art as appropriate.

In a first embodiment of the present disclosure:

as shown in fig. 1 and 2, the heating non-combustion smoking set of the present embodiment mainly includes a smoking set main body 1 and a smoking set holder 2. The smoking article body 1 and the smoking article holder 2 can be detachably plugged together. The cigarette holder 2 can fix the cigarette 3.

Although not explicitly shown in the figures, the cigarette 3 of the present embodiment includes a filter, a roll fixedly connected or integrally formed with the filter, and a cigarette heating but non-lighting member placed in the roll, which may be tobacco leaves, cut tobacco, or any member (e.g., sponge, paper, wood chips, etc.) coated with or adsorbed with tobacco tar. It will be understood by those skilled in the art that the term "capable of heating but not igniting the cigarette" in this embodiment and other embodiments of the present disclosure means that the cigarette 3 will not be ignited within a temperature range, which may be any feasible temperature range value, such as [ 80 ℃, 150 ℃ ], [ 100 ℃, 300 ℃ ], [ 120 ℃, 250 ℃ ], and the like.

As shown in fig. 2, the smoking article body 1 mainly includes an outer shell 11, an inner core assembly 12 disposed inside the outer shell 11, and a heater pin 13 disposed at one end of the inner core assembly 12. In which the housing 11 is provided with a through hole 111 (as shown in fig. 4). Although not shown in the drawings, the core assembly 12 includes a battery for supplying power to the heating pin 13 so that the heating pin 13 is heated, and a controller for controlling whether or not the battery supplies power to the heating pin 13 and the power supply. Since the technical means for supplying power to the heating pin 13 by the battery and the technical means for controlling the operation of the battery by the controller can be realized by the conventional technical means or the conventional technical means in the field, the description thereof will not be made herein.

As shown in fig. 3, the cigarette holder 2 mainly includes a cigarette holder body 21 and a heat conductive cover 22. Wherein, the cigarette holder main body 21 comprises a large diameter section 211 and a small diameter section 212 which are fixedly connected or integrally manufactured. In the use state, the small-diameter section 212 is inserted into the housing 11 such that one end of the large-diameter section 211 near the small-diameter section 212 abuts one end of the housing 11. Further, the cigarette holder main body 21 is provided with through holes 213, and the through holes 213 penetrate the large-diameter section 211 and the small-diameter section 212, respectively. The smoke clamp body 21 further includes a partition plate 214 disposed within the small diameter section 212, the partition plate 214 being fixedly connected to or integrally formed with the small diameter section 212.

With continued reference to fig. 3, the heat conductive cap 22 is disposed within the small diameter section 212 and the heat conductive cap 22 is fixedly coupled to the partition 214. Preferably, the heat conducting cover 22 and the partition 214 are fixedly connected together in a sealing manner, for example, by welding, gluing, clamping, etc. Further, the partition plate 214 is provided with a through hole (not shown) which is aligned with the heat conductive cover 22 so that the heating pin 13 can pass through the through hole and be inserted into the heat conductive cover 22.

It will be understood by those skilled in the art that the cigarette holder body 21 may be provided in any other feasible form, such as a hollow straight rod, an L-shaped or V-shaped hollow rod, etc., provided that the cigarette 3 can be fixed and the heat-conducting cover 22 can be fixed.

Referring to fig. 3, the heat conductive cover 22 is provided with a plurality of air holes 221. The plurality of ventilation holes 221 are equally spaced in the circumferential direction of the heat conductive cover 22, and the distribution density of the plurality of ventilation holes 221 gradually increases from the root of the heat conductive cover 22 (the lower portion of the heat conductive cover 22 in fig. 3) to the top of the heat conductive cover 22 (the upper portion of the heat conductive cover 22 in fig. 3). It can be understood by those skilled in the art that the plurality of ventilation holes 221 may have equal or unequal hole diameters. Illustratively, the apertures of the plurality of ventilation holes 221 gradually increase from the root of the heat conductive cover 22 (the lower portion of the heat conductive cover 22 in fig. 3) to the top of the heat conductive cover 22 (the upper portion of the heat conductive cover 22 in fig. 3).

It will be understood by those skilled in the art that the above distribution of the plurality of ventilation holes 221 on the heat conductive cover 22 enables air entering the heat conductive cover 22 from the lower end of the cigarette holder main body 21 in fig. 3 to flow into the cigarette 3 at a constant flow rate through the plurality of ventilation holes 221. In other words, the distribution pattern of the plurality of ventilation holes 221 on the heat conductive cover 22 can make the air flow passing through each ventilation hole 22 equal or nearly equal. On the contrary, if the plurality of ventilation holes 221 of the heat-conducting cover 22 do not adopt the distribution pattern, it may cause that most of the air entering the heat-conducting cover 22 is discharged from the root of the heat-conducting cover 22 (the portion of the heat-conducting cover 22 close to the partition plate 214) and only a small portion of the air entering the heat-conducting cover 22 is discharged from the top of the heat-conducting cover 22 (the portion of the heat-conducting cover 22 far from the partition plate 214).

As shown in fig. 4 to 6, in the use state, the smoking set 2 is inserted into the smoking set body 1 such that the heating pin 13 is also inserted into the heat-conducting cover 22; the cigarette 3 is inserted into the through-hole 213 of the cigarette holder 2, and the heat conductive cover 22 is inserted into the cigarette 3.

With continued reference to fig. 4 to 6, in the use state, an annular gap 4 is formed between the heating pin 13 and the heat conducting cover 22. In other words, a gap having a circular cross section is formed between the heating pin 13 and the heat conductive cover 22. An air inlet channel 5 is formed between the cigarette clamping device body 1 and the cigarette clamping device 2, one end of the air inlet channel 5 is communicated with the through hole 111 on the shell 11 and is communicated with the outside of the heating non-combustion smoking set, and the other end of the air inlet channel 5 is communicated with the inner cavity of the heat conducting cover 22. When a user sucks the cigarette 3, negative pressure is formed inside the cigarette 3, and the negative pressure drives air outside the non-combustion smoking set to enter the air inlet channel 5 from the through hole 111 and further enter the heat conduction cover 22, and then enters the cigarette 3 from the air holes 221 in the heat conduction cover 22, and finally enters the oral cavity of the user.

Furthermore, the annular gap 4 can be configured as any feasible gap by those skilled in the art, such as a C-shaped cross section gap, a spiral gap, a semi-annular cross section gap, and the like.

Alternatively, the cross-section of the heat conduction cover 22 is gradually reduced from the root of the heat conduction cover 22 to the top of the heat conduction cover 22, so that the annular gap 4 is gradually reduced from the root of the heat conduction cover 22 to the top of the heat conduction cover 22, thereby enabling the air in the heat conduction cover 22 to sufficiently exchange heat with the heating pins 13 and enabling the temperature between each part of the air in the heat conduction cover 22 to be substantially the same.

As shown in fig. 4 and 5, in the use state, an annular space is formed between the small diameter section 212 of the cigarette holder 2 and the outer shell 11 of the smoking set body 1, and the end of the small diameter section 212 far away from the large diameter section 211 is also spaced from the inner core assembly 12, so that the outer shell 11, the cigarette holder body 21 and the inner core assembly 12 jointly enclose the aforementioned air inlet channel 5.

Further, in order to ensure the sealing property of the air inlet passage 5, a sealing member is provided on the smoking set body 1 or the smoking set 2 so that the smoking set body 1 and the smoking set 2 can be sealingly inserted together by the sealing member. As an example one: the one end that the big diameter section 211 of pressing from both sides cigarette ware 2 is close to little diameter section 212 is provided with the sealing washer, when smoking set main part 1 and pressing from both sides cigarette ware 2 and pegging graft together, this sealing washer can with the shell 11 butt of smoking set main part 1 to realize the sealed between smoking set main part 1 and the cigarette ware 2 of pressing from both sides. As example two: the end of the outer shell 11 of the smoking set main body 1 close to the cigarette clamping device 2 is provided with a sealing ring, and when the smoking set main body 1 and the cigarette clamping device 2 are plugged together, the sealing ring can be abutted against the end of the large-diameter section 211 of the cigarette clamping device 2 close to the small-diameter section 212.

The operation principle of the heating non-combustion smoking set of the present embodiment will be briefly described with reference to fig. 4 to 6.

As shown in fig. 4 to 6, when the controller on the smoking set body 1 receives a command from the user to press the switch on the smoking set body 1, the battery supplies power to the heating pin 13, and the heating pin 13 is heated. Then, when the user smokes the cigarette 3, a negative pressure is formed inside the cigarette 3, and the negative pressure drives air outside the non-combustion smoking set to enter the air inlet channel 5 from the through hole 111, and further enter the heat conduction cover 22, and then enter the cigarette 3 from the air holes 221 on the heat conduction cover 22, and finally enter the oral cavity of the user.

In the process that the user smoked cigarette 3, the heat that heating needle 13 produced can be absorbed earlier to the air that enters into in the heat conduction cover 22 from inlet channel 5, then from the flow direction cigarette 3 of the medium velocity of flow in a plurality of bleeder vents 221 again for the air current of high temperature can heat cigarette 3 evenly, prevents that the heat from gathering in cigarette 3, carries out the overheat to cigarette 3, influences user's taste.

In a third embodiment of the present disclosure:

as shown in fig. 8, the present embodiment is different from the foregoing first embodiment in that an air intake passage 5 is provided to the smoking article body 1. Specifically, the air intake passage 5 includes a through hole (not shown) formed in the housing 11 and a recess (not shown) formed in the core assembly 12. As can be readily seen in figure 8, a clearance fit may be employed between the small diameter section 212 of the smoking article 2 and the outer shell 11 of the smoking article body 1.

In a fourth embodiment of the disclosure:

although not shown in the drawings, the present embodiment is different from the first embodiment in that the housing 11 no longer has the through hole 111, but a U-shaped, C-shaped, semicircular or other arbitrary-shaped notch is provided at one end of the housing 11 close to the cigarette holder 2; or, a U-shaped, C-shaped, semicircular or other notch with any shape is arranged on the large-diameter section 211 of the cigarette clamping device 2; so that the air intake passage 5 communicates with the outside of the non-combustion smoking set via the notch.

In a fifth embodiment of the present disclosure:

although not shown in the drawings, the present embodiment is different from the aforementioned first embodiment in that the plurality of ventilation holes 221 are distributed at unequal intervals in the circumferential direction of the heat conductive cover 22. The distribution density of the plurality of ventilation holes 221 is equal to or gradually decreases from the root of the heat conductive cover 22 (the lower portion of the heat conductive cover 22 in fig. 3) to the top of the heat conductive cover 22 (the upper portion of the heat conductive cover 22 in fig. 3). Or those skilled in the art can set the distribution pattern of the plurality of air holes 221 to any other pattern according to the requirement, for example, the plurality of air holes 221 are randomly set on the heat conductive cover 22.
