Description

Accelerated heat conduction atomizing device and use method

Technical Field

The invention belongs to the field of smoking sets, and particularly relates to an accelerating heat conduction atomizing device and a using method thereof.

Background

Related researches show that the traditional cigarette has a burning temperature of above 800 ℃, and the cigarette can generate more than 5000 chemical substances in the burning process, wherein more than 80 chemical substances are carcinogenic, and the generated smoke has a considerable harm to non-smoking people. The heating non-combustion technology is a technology for directly heating tobacco through a smoking set but not burning to generate smoke, and harmful substances generated by the heating mode are greatly reduced compared with harmful substances generated by burning traditional cigarettes, so that the harm to the body can be reduced while the requirements of consumers are met.

The main appliance of the heating non-combustion technology is a heating non-combustion smoking set, and the heating non-combustion smoking set heats tobacco materials so as to generate pyrolysis reaction, so that the tobacco materials are just heated to a degree sufficient for emitting tobacco taste and smoke so as to be sucked by a user.

Existing heating non-combustible smoking articles, whether in a rod-like or box-like configuration, generally have a smoking chamber therein for holding a tobacco product, a heating element for heating the tobacco product to form a smoke, a battery for providing power to the heating element, a circuit for connecting the battery to a power source and a circuit board carrying the circuit, a control circuit for controlling the battery to provide power to the heating element and a circuit board carrying the circuit, etc.

Compared with a box-shaped structure, the heating non-combustion smoking set with the rod-shaped structure is popular with more and more consumers because of the small size, convenient holding and more accordant with the hand feeling of the traditional cigarettes. However, compared with the box-shaped structure, the rod-shaped structure has the defect of limited internal installation space, and the structures such as the battery, the heating element, the smoke cavity and the like are integrated in the smaller installation space, so that on one hand, the axial dimension and the radial dimension of the rod-shaped structure are greatly influenced, and on the other hand, the connection and the positioning of the circuit board and the assembly of the components into the rod-shaped shell after the assembly of the components are influenced.

For example, the connection between the circuit board and the circuit board of the existing heating non-combustion smoking set is mostly soldered on the circuit boards at both ends by using wires to realize electrical connection, which is affected by other components and spaces. For this connection mode: on one hand, the radial dimension of the assembled battery, the wire and the circuit board can be increased, if the external dimension of the smoking set is certain, the smoking set can be assembled by the three, the volume of the battery is required to be reduced, the capacity of the battery can be reduced by the reduction of the volume of the battery, so that the cruising ability of the smoking set is greatly reduced, if the external dimension of the smoking set is not certain, the dimension of the wire is added under the condition of normally heating the battery dimension required by the non-burning smoking set, the external dimension of the smoking set can be increased, the overall weight of the smoking set is increased, and the hand feeling of a consumer can be reduced due to the thickening of the periphery; on the other hand, because of the softness of the wires, it is difficult to ensure mass consistency in positioning and welding.

The patent of the invention, issued to CN201910601144.5, discloses a heating non-combustible smoking article comprising: a housing having a hollow cavity; the circuit assembly comprises a battery and a flexible circuit board extending along the hollow cavity, one end of the flexible circuit board is provided with a first circuit area, and the battery is electrically connected with the first circuit area; and the circuit board supporting member is arranged in the hollow cavity and is matched with the inner wall of the hollow cavity, the circuit board supporting member extends along the axial direction of the battery, one end of the battery abuts against one end of the circuit board supporting member, and the first circuit area is fixed on the circuit board supporting member. The circuit board supporting member can form positioning support for one end of the flexible circuit board, can provide an abutting surface for the battery, is beneficial to keeping the original connection relation and the fixed relation between the flexible circuit board and the battery in the assembly process, and enables the whole assembly process to be more convenient, rapid and efficient. Although the heating non-combustion smoking set can heat low-temperature non-combustion cigarettes, the heating area is limited in part of the low-temperature non-combustion cigarettes, the whole low-temperature non-combustion cigarettes cannot be heated, meanwhile, the heating temperature of tobacco contacted with the heating assembly is high due to lack of heat conduction, the heating temperature of tobacco far away from the heating assembly is low, and the whole low-temperature non-combustion cigarettes are heated unevenly, so that the smoking taste is affected.
