Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

A double-sided heated tobacco cigarette as shown in Figure 1, it includes a mouthpiece 1 and a smoke chamber 2 that match each other, and a smoke generator 4 and a heating device 3 that provides a heat source are arranged in the smoke chamber 2, and the smoke generator 4 uses smoke The central axis of the cavity 2 is symmetrically arranged, one end of the smoke generator 4 is connected to the mouthpiece 1, and the other end of the smoke generator 4 is connected to the heating device 3; the smoke generator 4 includes a tobacco product area 4.3, which is used to place Tobacco products can be made into circular, square and other structural forms; an outer heating layer 4.1 is provided between one outer wall of the tobacco product area 4.3 and the inner wall of the smoke cavity 2, and an inner layer is provided on the other outer wall of the tobacco product area 4.3 The heating layer 4.2 can increase the heating area of the tobacco product through double-sided heating.

An outer thermal insulation layer 4.4 is provided between the outer heating layer 4.1 and the inner wall of the smoke chamber 2. By selecting the thickness of the outer thermal insulation layer 4.4, the temperature of the outer wall of the smoke chamber 2 is kept at a surface temperature of 42°C or below, and the smoke The outer wall of the cavity 2 can also be used as the outer heating layer 4.1; the outer wall of the inner heating layer 4.2 is provided with an inner heat insulation layer 4.5; an inner layer bracket 4.6 is arranged between the inner heat insulation layer 4.5, and the inner layer bracket 4.6 starts It plays a role in fixing and supporting the inner layer parts, tobacco products and outer layer parts of the tobacco smoke generator, and the inner layer support 4.6 can be removed through the position of the cigarette holder 1, and the tobacco products can be replaced to realize repeated use.

In this embodiment, the sections of the inner wall of the outer heating layer 4.1 and the outer wall of the inner heating layer 4.2 are both cylindrical, and their structures are shown in FIG. 2 .

As another solution of this embodiment, the sections of the inner wall of the outer heating layer 4.1 and the outer wall of the inner heating layer 4.2 are regular polygons, that is, the inner wall of the outer heating layer 4.1 and the outer wall of the inner heating layer 4.2 are concave-convex, which can increase The structure of the contact area between the tobacco product and the heating layer is shown in FIG. 3 .

The heating device 3 is set on the head of the smoke cavity 2, and it includes a power supply 3.1 connected to each other, an intelligent control circuit 3.2 and an indicator display area 3.3, the indicator display area 3.3 is set at the outermost end of the smoke cavity 2, and the power supply 3.1 is set at the smoke generator The power supply 3.1 is connected to the outer heating layer 4.2 in the outer layer smoke generator 4, and the intelligent control circuit 3.2 is arranged between the indication display area 3.3 and the power supply 3.1. The power supply 3.1 provides heat for the smoke generator; the intelligent control circuit 3.2 includes controlling the temperature of the inner layer smoke generator and the outer layer smoke generator, controlling the discharge of the power supply 3.1, controlling the on-time of the circuit, and including controlling the entire current loop Multiple functions such as control; the indication display area 3.3 is one or more functions of the connection indication of the indication circuit circuit, the power supply energy indication, the number of suction ports, the power supply working status and the power supply current flow indicator.

Under the condition that the power supply 3.1 provides electric energy, the temperature of the outer layer heating layer 4.1 and the inner layer heating layer 4.2 rises to the range of about 150°C to 400°C, within this temperature range, the tobacco products in the tobacco product area 4 Some volatile and tobacco-specific aroma components are dry-distilled and atomized to simulate the generation of smoke. In order to prevent the temperature of the outer heating layer 4.1 and the inner heating layer 4.2 from rising too high or too low, the intelligent control circuit 3.2 realizes reasonable control of the temperature and ensures that the temperature is within the range of 150°C to 400°C.

In addition, the cigarette holder 1 in the present invention has a certain length, generally 5mm-30mm, preferably 10mm-20mm, because the flue gas passes through the higher heating laminar flow, the temperature is higher, and the cigarette holder can not only reduce the temperature of the flue gas , It can also filter the flue gas to a certain extent.

A key switch 5 is arranged between the smoke generator 4 and the heating device 3, the key switch 5 is arranged on the outer wall of the smoke cavity 2, and the key switch 5 is turned on before the suction, the key switch 5 can artificially control the connection time of the circuit At the same time, the intelligent control circuit 3.2 can detect the temperature of the inner and outer heating layers. When the temperature is lower than 150°C, press the button switch 5, and the circuit is connected; when the temperature is higher than 400°C, even if the button switch is pressed, the circuit is closed. It is in the off state, which can better protect the power supply 3.1 and the elements of the inner and outer heating layers.

The invention provides a new type of cigarette that heats tobacco inside and outside, which can increase the heating area of tobacco products, can simulate the burning of cigarettes, reduce the harm of second-hand smoke caused by cigarette burning to consumers and non-smokers, and effectively avoid the danger of cigarette fires caused by open flames .
