Description

An electric heating smoking device that heats tobacco from the outside

technical field

The invention relates to an electric heating smoking device.

Background technique

Since the "Framework Convention on Tobacco Control" came into effect, the global tobacco industry has faced pressure from various parties. The development of new low-harm tobacco products is the focus of research and development by major tobacco companies around the world. At present, new heating tobacco products mainly include carbon heating and electric heating. Philip Morris focuses on electric heating cigarettes, and has developed The relevant electric heating cigarette products have been developed. The maximum heating temperature of this product is about 500°C, which is lower than the 950°C of traditional cigarettes, which significantly reduces the release of harmful components of cigarettes and environmental smoke. At present, electric heating cigarettes are mainly in the form of inner needle insertion and peripheral heating of tobacco products. The inner needle heating has the characteristics of small heating area but high heating efficiency; the peripheral heating has the characteristics of large heating area but low heating efficiency. Shortcomings.

Contents of the invention

In order to solve the deficiencies of the prior art, the invention provides a novel electric heating smoking device.

The above-mentioned purpose is achieved through the following technical solutions:

An electric heating smoking device that heats tobacco from the outside, including a mouthpiece section, a tobacco heating section and a power supply section, the power supply section is composed of a casing, a battery and a circuit inside the casing, and a circuit switch outside the casing Composition, the tobacco heating section is composed of a columnar heat source, a tobacco filling cavity and a casing, the two ends of the columnar heat source are respectively connected to the mouthpiece section and the circuit, the tobacco filling cavity is located inside the columnar heat source and passes through the columnar As for the heat source, at least one side of the tobacco filling cavity is connected with the shell, and the shell is provided with a ventilation hole at the part connected with the tobacco filling cavity.

One end of the shell is fixedly connected with the mouthpiece section.

The cross section of the tobacco filling chamber is cross-shaped, and the tobacco filling chamber has four sides connected with the shell.

The beneficial effects of the present invention are:

The invention increases the contact area between the heat source and the tobacco product, so that the tobacco product is heated more evenly, has higher heating efficiency and faster smoke generation, and can be smoked within 0.5 minutes after the circuit is energized, and the smoke is rich and fragrant. Stable, low irritation, less miscellaneous gas. The present invention can conveniently fill tobacco products into the tobacco filling chamber by connecting the shell with the mouthpiece section. The tobacco filling chamber with a cross-shaped cross section can not only fill more tobacco products, but also further improve the heating efficiency, so that Tobacco is heated more evenly.

The invention also has the advantages of simple structure and low production cost.

Description of drawings

FIG. 1 is a schematic diagram of an axial sectional structure of the electric heating smoking device in Embodiment 1. FIG.

Fig. 2 is a schematic radial cross-sectional view of the tobacco heating section of the electric heating smoking device in Embodiment 1.

Fig. 3 is a schematic diagram of a radial cross-sectional structure of the tobacco heating section of the electric heating smoking device in Example 2.

Among the figure: 1-cigarette holder section, 2-tobacco heating section (21-column heat source, 22-tobacco filling cavity, 23-shell, 24-air intake), 3-power supply section (31-housing, 32-battery, 33-circuit, 34-circuit switch).

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment 1: Fig. 1 and Fig. 2 show an electric heating smoking device, which consists of a mouthpiece section 1, a tobacco heating section 2 and a power supply section 3. The internal battery 32 is composed of a circuit 33 and a circuit switch 34 arranged outside the casing 31. The tobacco heating section 2 is composed of a columnar heat source 21, a tobacco filling cavity 22 and a shell 23 matched with the columnar heat source 21. Both ends of the columnar heat source 21 are respectively connected to the mouthpiece section 1 and the circuit 33. The tobacco filling cavity 22 is located inside the columnar heat source 21 and passes through the columnar heat source 21 in the axial direction. The cross section of the tobacco filling cavity 22 is cross-shaped And the four sides are all connected with the shell 23, the shell 23 is provided with several ventilation holes 24 communicating with the tobacco filling cavity 22 at the position connected with the tobacco filling cavity 22, and one end of the shell 23 is fixedly connected with the mouthpiece section 1 .

When in use, first pull out the shell 23 toward the mouthpiece section 1, separate the shell 23 from the columnar heat source 21, then fill the tobacco product from the mouthpiece end into the tobacco filling cavity 22, then put on the shell 23, and put the shell 23 The ventilation holes 24 on the top are aligned with the four sides of the tobacco filling cavity 22. Since the contact surface area of the tobacco product and the columnar heat source 21 is relatively large, it can quickly rise to the atomization temperature to generate smoke. Therefore, after the circuit 33 is energized, the It can be smoked within 0.5 minutes, and the tobacco products are evenly heated, and the smoking effect is better.

Embodiment 2: Fig. 3 shows another electric heating smoking device, its structure is the same as that of Embodiment 1, the difference is that the tobacco filling chamber 22 is elongated, and the two sides of the tobacco filling chamber 22 are connected to The casing 23 is connected, and the casing 23 is provided with a ventilation hole 24 at a position connected with the tobacco filling cavity 22 .
