3444 results about "Tar" patented technology

Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. Production and trade in pine-derived tar was a major contributor in the economies of Northern Europe and Colonial America. Its main use was in preserving wooden sailing vessels against rot. The largest user was the Royal Navy of the United Kingdom. Demand for tar declined with the advent of iron and steel ships.

Electronic Atomization Cigarette

ActiveUS20070267031A1Reduce cancer riskRespiratorsNervous disorderVapor–liquid separatorTar
The present invention relates to an electronic atomization cigarette which only contains nicotine without harmful tar. The electronic atomization cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An electronic circuit board, a normal pressure cavity, a sensor, a vapor-liquid separator, an atomizer, a liquid-supplying bottle are sequentially provided within the shell, wherein the electronic circuit board comprises an electronic switching circuit and a high frequency generator. A stream passage of the sensor is provided on one side of the sensor, and a negative pressure cavity is provided in the sensor. The atomizer and the liquid-supplying bottle is in contact with each other. An atomization cavity is arranged in the atomizer. A retaining ring for locking the liquid-supplying bottle is provided between one side of the liquid-supplying bottle and the shell, and an aerosol passage is provided on the other side of the liquid-supplying bottle. The air inlet, normal pressure cavity, vapor-liquid separator, atomizer, aerosol passage, gas vent and mouthpiece are sequentially interconnected. The advantages of the present invention include smoking without tar, significantly reducing the cancerogenic risk. Furthermore, users still feel as if they are smoking and experiencing the same excitement, and the cigarette is no need to be lit and is no fire risk.

Visible heating atomizing cigarette

InactiveCN103263083AMake up for the lack ofReduce releaseTobacco devicesAdditive ingredientTar
The invention discloses a visible heating atomizing cigarette which comprises a cigarette body and a cigarette holder. The cigarette body comprises a heating area, an atomizing area and a power source area. The heating area, the atomizing area and the power source area of the cigarette body are sequentially communicated with the cigarette holder through an airflow channel. A case of the heating area is made of heat-insulating transparent materials. Tobacco shreds or remanufactured tobacco leaves are filled in the heating area. Heating wires are arranged between the case and the tobacco shreds. A liquid storing cavity is formed in the atomizing area. The liquid storing cavity is connected with an atomizer in the power source area. The power source area is formed by electrically connecting a battery, a control circuit, a pneumatic inductive switch and the atomizer. When the visible heating atomizing cigarette is burnt and smoked, a user can breathe mixed smoke which is generated after heating of the tobacco shreds and atomizing of fragrance into the mouth through suction, and the sucking effect which is the same as that of a common cigarette is achieved. The visible heating atomizing cigarette has the dual advantages of electronic cigarettes and electrical heating cigarettes and is large in smoke amount, the amount of released harmful ingredients can be reduced greatly, tar cannot be generated, harm of passive smoking and the smoke of side flowing are avoided, and the visible heating atomizing cigarette is an effective substitute of a traditional combustible cigarette.

Novel carbon heating electronic cigarette

InactiveCN103271447AImprove the problem of insufficient smoke aromaReduce releaseTobacco devicesPipe TobaccoTar
The invention discloses a novel carbon heating electronic cigarette which is formed by a carbon heating area, an electronic atomization area and a cigarette holder in sequence. The carbon heating area, the electronic atomization area and the cigarette holder are separated one another through breathable partition plates. The carbon heating area is formed by a carbolic matter heat source, an aerosol forming part and a fragrance forming part in sequence. The electronic atomization area is formed by connecting a power supply, an atomizer and a liquid storage cavity electrically. The cigarette holder is a conventional cellulore filter stick. When the novel carbon heating electronic cigarette is sucked, the carbolic matter heat source heats aerosol forming matters and pipe tobacco to form aerosol, sucked airflow triggers a pneumatic inductive switch to be opened, the atomizer works, tobacco liquid in the liquid storage cavity is atomized to form smog, and the smog and the aerosol are sucked into a mouth. The novel carbon heating electronic cigarette integrates advantages of carbon heating type cigarettes and advantages of electronic cigarettes, is novel in appearance and easy to manufacture, does not generate sidestream gas, can meet requirements for cigarette fragrance and nicotine of a consumer, and is low in the content of tar and harmful ingredients.
