Description

An electronic cigarette

technical field

The utility model relates to the field of tobacco, in particular to an electronic smoking set, which belongs to the electric heating type smoking set.

Background technique

With the deepening of research on smoking and health, some scientific studies have shown that most of the harmful substances in cigarettes are produced by burning tobacco and enter the human body through smoking. Current research also shows that there are more than 2,740 kinds of components in the smoke produced by tobacco combustion, which are mainly produced by pyrolysis of tobacco. The most difficult thing for non-smoking people to accept is that the passive smoking that causes harm to others due to smoking is also mainly caused by the sidestream smoke produced by burning cigarettes. Therefore, the public is particularly resistant to smoking, especially smoking in public places, and a social consensus has gradually formed. As one of the member states of the World Health Organization, my country has signed the "Framework Convention on Tobacco Control." However, although the view that smoking is harmful to health has been accepted by the public, due to the unique charm of tobacco, the total number of smoking populations in the world is still on the rise. Therefore, while recognizing that smoking is harmful to health, it is particularly necessary to develop a safer smoking method that can meet the special needs of smokers and reduce the harm of smoking to the public.

However, due to consumption habits, traditional smokeless tobacco products (smokeless tobacco) such as chewing tobacco and snuff cannot be accepted by consumers at present. Not often. Moreover, this type of product cannot provide the real feeling of holding a cigarette when smoking a cigarette, and at the same time, some flavor substances in tobacco that can only be released by heating cannot be released. In addition, the safety of this type of product is also currently under debate. Therefore, developing a tobacco form that does not produce sidestream smoke and enables tobacco consumers to enjoy the unique fragrance of tobacco has become a current research hotspot.

The new smokeless smoking devices disclosed in Chinese patents 93115275.5, 96104954.5 and 96118402.7 can solve the problem of sidestream smoke, but they either use non-tobacco materials or tobacco essential oil extracts to provide smokers in the form of atomization, and cannot provide tobacco Consumers feel satisfied when smoking cigarettes, and at the same time, the smoke flavor is not enough. Chinese patents CN88101196 and 89108679.X applied by Reynolds Tobacco Company provide a cigarette that provides tobacco flavor by heating rather than by burning tobacco or any other material. However, this tobacco product tends to have a burning carbon tip and thus the amount of CO in the smoke is higher. Makes it more expensive due to the special carbon tip. U.S. Patent No. 4,714,082 discloses a smoking appliance that uses fiberglass insulation to surround the fuel and the aerosol generator, and generates smoke through heating. However, due to the elastic fiberglass insulation sleeve used, it is difficult to carry out mechanical production on a modern scale. In addition , In the process of production and transportation, the glass fiber is easy to fall off, and may be inhaled by the smoker, causing danger. Chinese patents 91105820.6, 95190277.6, and 96194107.3 applied by Philip Morris Tobacco Company disclose a smoking appliance using a sleeve-type electric heating device. The possibility of generating sidestream smoke is avoided. Yet this device adopts higher temperature to heat shredded tobacco when in use, makes shredded tobacco close to carbonization, thereby becomes loose, falls off easily in the sleeve and is difficult for removing, brings inconvenience to reuse. Simultaneously this device design is complicated, and cost is higher, and non-general consumer can accept.

Detailed ways

The utility model is further described below in conjunction with accompanying drawing:

As shown in Figures 1 and 2: the electronic smoking device consists of a suction unit, an electric heating unit connected to the suction unit, and a cigarette sheet 12 arranged in the electric heating unit. The suction unit and the electric heating unit are connected by The parts 10 are connected to each other in a threaded manner, the suction unit is composed of a cigarette holder 1 and an air suction channel 2, and the electric heating unit includes an outer sleeve 8, a liner 6 arranged in the outer sleeve, a power supply 9 installed in the liner, a power supply The switch and the electric heating sheet arranged at the connecting part of the suction unit and the electric heating unit are composed of the airflow trigger switch 3 arranged in the suction channel, and an air intake is left between the outer sleeve 8 and the liner 6 Passage 7, the air inlet end of outer sleeve 8 is provided with mesh 5, and electric heater is designed as two pieces, and smoke sheet 12 is sandwiched between two heating sheets, and in order to facilitate smoke to pass through, in the electric heater near the filter tip position The heating sheet is a porous heating sheet 4 (as shown in Figure 3), on which processing is conducive to through-holes and grooves for airflow to pass through, and the smoke sheet 12 is loose in material and is designed with a plurality of holes (as shown in Figure 4), to ensure The generated flue gas dissipates quickly and passes smoothly. The airflow channel between the heating sheet 11 and the smoke sheet 12 and the preset airflow channel between the heating sheet 11 and the inner wall of the connecting piece 10 are all connected with the suction channel 2 of the suction unit and the air intake channel 7 of the electric heating unit. They communicate with each other to ensure the air flow of the whole suction system.

When in use, unscrew the suction part and the heating part through the thread of the joint part, put the special cigarette block into the cigarette chamber, then screw on the heating part, start to suck, the airflow trigger switch 3 is activated, and the power is turned on 9 , the heating sheet starts to generate heat, and the air enters from the mesh 5 at the far mouth end, passes through the air intake channel 7 between the liner 6 and the outer sleeve 8, and reaches the smoke sheet chamber through the small holes in the heat insulation layer on the side of the heating element, and the smoke sheet 12 Under the heating of the heating element, the relevant components are released, mixed with the incoming air, and enter the smoke channel through the gaps in the tobacco block and the small holes on the porous heating sheet, and finally enter the oral cavity through the filter. When one smoke sheet is used up, unscrew the connecting part to replace the smoke sheet.

After multiple uses, the suction section can be cleaned as needed. It is the chip chamber that often needs to be cleaned, because after the cigarette block is heated and used, it may leave residues in the chip chamber. Due to the shallow design of the smoke chamber, it is very convenient to clean the smoke chamber, which can be easily completed with a small brush. The porous heating sheet arranged on the top of the smoke sheet chamber also functions as a filter. Since the heated smoke sheet becomes dry and loose and generates debris, the existence of the porous filter sheet makes it difficult to penetrate into the flue gas channel. Even if very fine debris enters the smoke channel, it will be trapped at the filter tip and will not enter the mouth, causing discomfort. As the number of uses increases, the mouthpiece will become less clean, and the air permeability will also decrease, thereby increasing the suction resistance, and the mouthpiece can be removed for replacement. When the flue gas channel needs to be cleaned, it can also be disassembled for cleaning at any time. Such a design can effectively keep the suction system clean and hygienic.
