Problems solved by technology

Due to the limited thickness and heating method of conventional cigarettes, there are problems of low heat utilization efficiency and uneven distribution of heat field. Therefore, in order to make the whole cigarette reach the required temperature, the maximum temperature during heating is usually designed to be 50% higher than the target temperature. ℃ above
Since the non-flame cigarette lighting device is usually small in size and poor in heat dissipation performance, such a high temperature will cause a large amount of heat, which will be hot during use, and because the structure of the non-flame c

Example Embodiment

[0029] Example 1

[0030] Such as figure 1 with 2 As shown, a high heat dissipation performance non-open flame cigarette lighter includes a accommodating cavity 1. The accommodating cavity includes an adjacent first accommodating room 11 and a second accommodating room 12; the first accommodating room 11 is provided with a battery 2 and In the circuit module 3 for controlling heating; an electric heating device 4 is provided in the second containing chamber 12, the electric heating device 4 is located at the lower end of the second containing chamber 12, and the electric heating device 4 is an electric heating wire layer or a heating film. The top of the second containment chamber 12 is provided with an opening 41 for inserting cigarettes into the electric heating device; the outer wall of the electric heating device 4 is provided with an insulation layer 5, and the insulation layer 5 is provided with a heat dissipation mechanism 6; A heat dissipation hole 111 is provided on the...

Example Embodiment

[0034] Example 2

[0035] This embodiment is the second embodiment of the present invention. The difference from Embodiment 1 is:

[0036] Such as image 3 with 4 As shown, the first heat dissipation fin group 63 includes a plurality of first heat dissipation fins 631. The first heat dissipation fins are distributed along the axis of the second receiving chamber 631. One end of the first heat dissipation fin 631 is connected to the first heat dissipation fin 631. The layers 61 are connected, and the other end faces the top of the second containing chamber 12. In the axial section of the second containing chamber, the first heat dissipation fin 631 and the first heat dissipation layer 61 form a first angle A, and the angle of the first angle is 30°~80°, preferably 45°. Airflow holes 6311 are provided on the first heat dissipation fins, and the axial cross-sectional length L of the first heat dissipation fins 631 gradually decreases toward the opening direction to reduce air resis...

Abstract

The invention provides a non-open-fire cigarette lighting device high in radiating performance. The non-open-fire cigarette lighting device comprises a first containing room and a second containing room which are adjacent. The first containing room is internally provided with a battery and a circuit module used for controlling heating. The second containing room is internally provided with an electric heating device. A heat insulating layer is arranged on the outer wall of the electric heating device so that the electric heating device can be insulated from the inner wall of the second containing room, heat transmission between the electric heating device and the inner wall of the second containing room is reduced, and influences brought by temperature rising when the electric heating device conducts heating are reduced. Meanwhile, a radiating mechanism is arranged outside the heat insulating layer and radiating holes are formed in the side face of the second containing room, heat transmitted out by the heat insulating layer can be effectively dissipated out, and the surface temperature of a containing cavity is reduced. Under the condition that the size of cigarettes is not reduced, the radiating performance of the non-open-fire cigarette lighting device is improved, the problem of hand scalding in the use process of the non-open-fire cigarette lighting device is solved, the experience of a user is improved, and meanwhile damage to an electronic element and the battery is reduced.

Description

technical field [0001] The invention relates to the field of cigarette heating devices, in particular to a flameless cigarette lighting device with high heat dissipation performance. Background technique [0002] In the prior art, in order to effectively volatilize the aroma components of cigarettes and achieve a similar effect to smoking cigarettes with open flames, the non-flame cigarette lighting device needs to uniformly heat the cigarettes to above 200°C. Due to the limited thickness and heating method of conventional cigarettes, there are problems of low heat utilization efficiency and uneven distribution of heat field. Therefore, in order to make the whole cigarette reach the required temperature, the maximum temperature during heating is usually designed to be 50% higher than the target temperature. ℃ or more. Since the non-flame cigarette lighting device is usually small in size and poor in heat dissipation performance, such a high temperature will cause a large am...
