Description

Accelerated heat conduction atomization device and use method

Technical Field

Background

Relevant researches show that the combustion temperature of the traditional cigarette is above 800 ℃, the cigarette can generate more than 5000 chemical substances in the combustion process, more than 80 chemical substances with carcinogenicity are generated, and the generated smoke has great harm to non-smoking people. The heating non-combustion technology is a technology for directly heating tobacco through a smoking set but generating smoke without combustion, harmful substances generated by the heating mode are greatly reduced compared with harmful substances generated by burning traditional cigarettes, and the harm to the body can be reduced while the requirement of consumers is 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 a pyrolysis reaction, so that the tobacco materials are just heated to a degree enough to give out tobacco taste and smoke for a user to suck.

Existing heated non-combustible smoking articles, whether rod-like or box-like, typically have a smoking chamber therein for holding a smoking article, a heating element for heating the smoking article to form an aerosol, a battery for supplying power to the heating element, an electrical circuit for connecting the battery to a power source and a circuit board carrying the electrical circuit, a control circuit for controlling the supply of power from the battery to the heating element and a circuit board carrying the electrical circuit, and the like.

Rod-shaped structure's heating not burn smoking set is compared with box-shaped structure, receives more and more consumers' favor because of having that the size is little, conveniently hold and more accord with the handheld sense of traditional cigarette. However, the rod-like structure has a limited installation space in the body compared to the box-like structure, and the integration of the above-mentioned battery, heating element, smoke chamber and other structures in the smaller installation space has a great influence on the axial dimension and radial dimension of the rod-like structure, and on the other hand, has an influence on the connection and positioning of the circuit board therein and the assembly of the components into the rod-like housing after assembly.

For example, under the influence of other components and space, the circuit boards of the existing heating non-combustion smoking set are mostly connected by adopting wires to be welded on the circuit boards at two ends so as to realize electric connection. For this connection: on one hand, the radial size of the assembled battery, the wire and the circuit board can be increased, if the external size of the smoking set is fixed, the volume of the battery needs to be reduced in order to meet the requirement that the assembled battery can be loaded into the smoking set, the capacity of the battery can be reduced due to the reduction of the volume of the battery, and therefore the cruising ability of the smoking set is greatly reduced, if the external size of the smoking set is not fixed, the external size of the smoking set can be increased under the condition that the battery size needed by the smoking set is not combusted through normal heating, the overall weight of the smoking set is increased, and the hand feeling of a consumer can be reduced due to the fact that the periphery of the smoking set is thickened; on the other hand, because the wire is soft, the positioning and welding of the wire are difficult to ensure the batch consistency.

The invention patent with the publication number of CN201910601144.5 discloses a heating non-combustion smoking set, which comprises: 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; the circuit board supporting member is arranged in the hollow cavity and 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 a positioning support for one end of the flexible circuit board, can provide a leaning surface for the battery, is favorable for keeping the original connection relation and the fixed relation between the flexible circuit board and the battery in the assembling process, and enables the whole assembling process to be more convenient, quicker and more efficient. Although this heating incombustible smoking set can realize the heating to low temperature incombustible cigarette, nevertheless because its heating region is restricted in partial low temperature incombustible cigarette, can't heat holistic low temperature incombustible cigarette, simultaneously, also because lack heat-conduction for the heating temperature that receives with the tobacco of heating element contact is high, and the heating temperature that the tobacco of keeping away from heating element received is low, and whole low temperature incombustible cigarette is heated inhomogeneously, influences and inhales the taste.
