Description

Technical Field

[0001] The utility model relates to the technical field of heat-not-burn smoking articles, in particular to an air guide device for air-heat-not-burn smoking articles. Background Art

[0002] Heat-not-burn tobacco products are mainly composed of cigarette cartridges and smoking utensils. When working, the aerosol generation section in the cigarette cartridge is heated at low temperature to volatilize and produce nicotine and fragrance. In the field of heat-not-burn smoking utensils, air heating, as a new heating method, has the advantages of clean heating process and no pollution.

[0003] However, the heating module of heat-not-burn tobacco products is generally located at the far end of the aerosol generating section of the cartridge. Due to the uneven heating of the aerosol generating material, the heating and baking effect of the aerosol generating material near the mouth end is often not as good as that at the far end. There may even be a situation where the aerosol generating material of the cartridge at the far end is carbonized but the baking at the near end is still insufficient, resulting in inconsistent puffing experience. In addition, since air heating is to preheat the gas first and then heat the cartridge with hot air, the heating efficiency is low, resulting in a long waiting time. Utility Model Content

[0010] Preferably, the diameter of the air guide tube is 1 / 4 to 1 / 3 of the diameter of the aerosol generating section of the cigarette cartridge.

[0011] Preferably, a pointed structure is provided on the top of the air guide tube to facilitate the insertion of the air guide tube into the aerosol generating section of the cigarette cartridge.

[0012] Preferably, the total length of the air guide tube and the pointed structure is slightly less than or equal to the length of the aerosol generating section of the cigarette cartridge.

[0013] Preferably, the air guide device is made of high temperature resistant heat insulating plastic material.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0027] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] Reference Figures 1 to 4 As shown, the utility model provides an air guide device 1 for an air-heating non-burning smoking device, comprising an air guide tube 11; an air guide channel 12 is arranged inside the air guide tube 11, and the air guide channel 12 is opened along the length direction of the air guide tube 11 and penetrates to the bottom end surface thereof. One or more air flow holes 13 are opened on the side wall of the air guide tube 11 to ensure that hot air can be dispersed to the surroundings, so that the hot air can be smoothly transported from the air guide channel 12 to the middle and rear part (near the mouth end) of the aerosol generating section 21 of the cigarette cartridge 2, so that the aerosol generating section 21 is heated evenly.

[0030] Among them, the bottom end of the air guide tube 11 is connected to the air guide chassis 14, and the air guide channel 12 is opened through the bottom end surface of the air guide chassis 14; the top of the air guide chassis 14 is annularly formed with a skirt structure 15, and the air guide chassis 14 and the skirt structure 15 form a limiting groove for collecting scattered particles, tar and other residues to prevent the residues from falling into the lower air duct of the smoking device and facilitate cleaning.

[0031] The air guide bottom plate 14 is provided with a plurality of air guide holes 16 , and the air guide holes 16 are provided from the top end surface to the bottom end surface of the air guide bottom plate 14 , and the air guide holes 16 are configured as micro holes to ensure that the heated air flow can smoothly bake the aerosol generating material at the far end of the nozzle.

[0032] The air flow holes 13 are opened along the length direction of the air guide tube 11 , and the length of the air flow holes 13 is 2 / 3 to 3 / 4 of the length of the air guide tube 11 ; the air flow holes 13 are opened at one end of the air guide tube 11 away from the air guide chassis 14 .

[0033] The diameter of the air duct 11 is 1 / 4 to 1 / 3 of the diameter of the aerosol generating section 21 of the cigarette cartridge 2. Taking the currently common diameter of the cigarette cartridge 2 of 7.2 mm as a reference, the diameter of the air duct 11 is preferably in the range of 1.8 mm to 2.4 mm. On the one hand, it ensures sufficient airflow, and on the other hand, it prevents the air duct 11 from excessively squeezing the aerosol generating substance, resulting in poor longitudinal airflow.

[0034] The top of the air guide tube 11 is chamfered to form a pointed knot 17 to facilitate the insertion of the air guide tube 11 into the aerosol generating section 21 of the cigarette cartridge 2. When in use, the air guide tube 11 is inserted into the aerosol generating section 21 of the cigarette cartridge 2, and the insertion depth of the air guide tube 11 and the pointed structure 17 is adapted to the length of the aerosol generating section 21. Considering the differences in the structure of the cigarette cartridge 2, there is a barrier section behind the aerosol generating section 21 of some cigarette cartridges 2. The total length of the air guide tube 11 and the pointed structure 17 is slightly less than or equal to the length of the aerosol generating section 21 of the cigarette cartridge 2, and the insertion depth is preferably not more than the aerosol generating section 21.

[0035] The air guide device 1 is made of high temperature resistant heat insulating plastic material, so as to allow hot air to directly pass through the middle and rear part (near the mouth end) of the aerosol generating section 21 .

[0036] The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model. Obviously, the above embodiments of the present utility model are only examples for clearly illustrating the present utility model, and are not limitations on the implementation methods of the present utility model. For ordinary technicians in the relevant field, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included in the protection scope of the claims of the present utility model.
