Benefits of technology

"The invention is an electronic smoking-substitute device that includes a tube containing a liquid to be inhaled, a heating element, and a power source. The device is designed to be disposable, meaning it can be disassembled without being recharged or refilled. The heating coil is more effective than previous designs, requiring less power to vaporize the liquid. The device is also lighter and more portable than previous designs. The liquid can contain a flavor substance and a scent, and the device can have a mouthpiece for inhaling the liquid. The device can also have a safety cut-off and a one-piece design, making it easier to dispose of. The power source is connected directly to the heating element, and the device contains a plastics material tube for better thermal efficiency and insulation."

Problems solved by technology

Conventional smoking devices, including cigarettes, cigars and pipes, are now known to be associated with a variety of problems.
They function by burning tobacco, which creates a flame, and which consequently presents a significant fire risk in many environments, including domestic dwellings.
Also, substances found in tobacco, for example tar, are believed to be associated with an increased risk of health problems, including life-threatening diseases such as cancer.
It is believed that inhalation by third-parties of smoke generated by smokers in closed environments also increases the risk of the third-parties developing such conditions.
The experience of others' smoke can also be unpleasant for third-parties, especially in restaurants and the like.
However, many smokers enjoy regular smoking, and may experience unpleasant psychological or even physiological symptoms if they are unable to smoke frequently.
That results in the devices being relatively heavy.
The batteries used in prior-devices are relatively low-power, and the device design results in inefficient transfer of heat, which means that vapour is produced slowly, and hence in smaller quantities than may be desirable.
Furthermore, frequent charging is required.

first example embodiment

[0046]the invention—an electronic cigarette 110—is shown in FIG. 2(a), and a second example embodiment of the invention—an electronic cigar 210—is shown in FIG. 2(b). In both cases, it will be apparent that the devices are substantially one-piece devices, comprising a tubular body 130, 230, a mouthpiece 150, 250, and an LED end 200, 300. It will be apparent that the one-piece nature of the devices 110, 210 eliminates the joins present along the length of prior-art cigarette 10, resulting in devices 110, 210 having a superior aesthetic appearance, and more closely resembling a conventional cigarette and cigar, respectively.

[0047]The internal construction of devices 110, 210 is shown in the cross-sections of FIGS. 3 and 4. It will be seen that the cigarette 110 and cigar 120 are very similar in internal construction, differing only slightly in their dimensions, save at their mouthpieces 150, 250.

[0048]The mouthpiece 150 of the cigarette 110 is a flattened tube for easy gripping betwee...

Abstract

An electronic smoking-substitute device 110 includes a tube containing a reservoir 310 containing a liquid. The liquid includes a substance to be inhaled by the user, for example a nicotine dilution. The device also has a heating element 320, the heating element is a coil and is in direct contact with the reservoir 310. A power source 340 is arranged to power the heating element.

Description

FIELD OF THE INVENTION[0001]This invention relates to electronic smoking-substitute devices. More particularly, although not exclusively, the present invention relates to electronic cigarettes and cigars, which provide a user with an inhalable vapour comprising nicotine or another substance, but which do not produce a flame or smoke.PRIOR ART[0002]Conventional smoking devices, including cigarettes, cigars and pipes, are now known to be associated with a variety of problems. They function by burning tobacco, which creates a flame, and which consequently presents a significant fire risk in many environments, including domestic dwellings. Also, substances found in tobacco, for example tar, are believed to be associated with an increased risk of health problems, including life-threatening diseases such as cancer. It is believed that inhalation by third-parties of smoke generated by smokers in closed environments also increases the risk of the third-parties developing such conditions. Th...
