Description

The electronics cigarette

Technical field

The utility model relates to the smoking cessation product scope, is specifically related to a kind of electronics cigarette.

Background technology

Tar in the tobacco contains a large amount of human body harmful's compositions, and Smoking is harmful to your health has become the whole mankind's common recognition.According to World Health Organization's statistics, the whole world has 5,000,000 people dead because of smoking every year approximately at present, and tobacco has become No. second " killer " after hypertension.The electronics cigarette is a kind of conventional cigarette substitute; Its effect is similar with common cigarette, can refresh oneself, satisfy craving for tobacco, makes the smoker produce floaty euphoria and loosens sense; But because the tobacco tar of electronics cigarette does not contain tar ingredients, so the electronics cigarette has obtained popular approval as the smoking cessation product.

Traditional electronics tobacco bale is drawn together interconnective tobacco rod assembly and lubricating cup assembly; Be provided with battery in the tobacco rod assembly; The lubricating cup assembly comprises cigarette holder, cigarette bullet and atomizer; Introduce the tobacco tar in the cigarette bullet through the foam nickel screen in the atomizer, then tobacco tar is atomized, thereby reach the effect of smoking after suction nozzle sucks human body.But there is following problem in above-mentioned traditional electronics cigarette:

1, the electronics cigarette of prior art adopts atomizer centre hole intake method, often occurs unnecessary tobacco juice in actual use and is back to the battery place along airflow line, causes battery circuit to damage.

2, the tobacco rod assembly of prior art adopts the contact thimble to contact with screw thread with the cigarette holder assembly and realizes being electrically connected conducting; Contact is connected an electrode respectively and separates through the insulation of silica gel separation sleeve the contact thimble with screw thread; But owing to the elasticity of silica gel separation sleeve can not be controlled the phenomenon that the atomizer thimble that is easy to generate and battery masthead pin can't touch; When rotation battery or atomizer, also often produce thimble and follow the problem of the electrode line disconnection of rotating and causing welding on the thimble, and the form of screw thread contact also exists because the phenomenon that the nuance generation negative pole of doing manual work can't contact.

3, the atomizer of prior art is an integral structure with the cigarette holder assembly all, after atomizer damages, will cause whole cigarette holder assembly to damage, and the service life of atomizer is shorter, therefore causes the service life of electronics cigarette shorter, and use cost is higher.

4, the electronics cigarette of prior art adopts electric connector to realize charging, and this charging must be connected firmly electric connector and could realize being electrically connected reliably, uses cumbersome.
