The bottom of the inner sleeve is provided with an atomization cavity. The side wall of the inner sleeve is provided with a plurality of air inlet grooves penetrating axially and communicated with the atomization cavity.

A water-based electronic cigarette liquid is disclosed. The water-based electronic cigarette liquid includes the following ingredients in parts by mass: 5-60 parts of water, 5-50 parts of smoke ingredient which is solid at normal temperature and is soluble in water, and 0-30 parts of glycerol. The electronic cigarette liquid in this invention has environmental protection, high safety, comfortable smoking taste, high smoke producing effect, and low viscosity.

Disclosed is an ultrasonic electronic cigarette atomizer. An atomizer shell, an atomization piece and a liquid guide structure are arranged in the atomizer. The liquid guide structure communicates with a liquid storage cavity in the atomizer shell. A heating body is further arranged in the atomizer shell. Both of the atomization piece and the heating body are in contact with the liquid guide structure, and both of the heating body and an atomization surface of the atomization piece communicate with an airflow passage, and a positive electrode and a negative electrode of the heating body are respectively connected with one end and the other end of a power supply. The heating body can not only quickly heat the tobacco tar to approach to its atomization temperature, but also can transfer a part of heat to the atomization piece, so that the atomization piece atomizes the tobacco tar quickly, shortening the atomization time.

Disclosed are a full-wave drive circuit for an ultrasonic atomizing sheet and an ultrasonic electronic cigarette. In an embodiment, the ultrasonic atomizing sheet full-wave drive circuit comprises a power supply module, a microprocessor, a high-frequency square wave generation circuit, an NMOS transistor and a resonance circuit configured to convert, on the basis of the NMOS transistor, a voltage signal outputted by the high-frequency square wave generation circuit into a full-wave oscillation signal, so as to drive the ultrasonic atomizing sheet to perform full-wave oscillation. A disclosed embodiment has low requirements for a boost module, low loss of the boost module, high power conversion efficiency, small volume, low loss of NMOS transistor and low cost, is easy for debugging, and has high reliability and good atomization effect.

An electronic cigarette, comprising a shell and a power supply installed in the shell, and the electronic cigarette further comprises a tobacco bin which is provided in the shell and communicates with the outside air, and a suction nozzle which communicates with the tobacco bin; and a piezoelectric ceramic piece which clings to the tobacco bin is provided in the shell, the piezoelectric ceramic piece is a bearing surface of the tobacco bin on which a tobacco material is loaded as well as a heating surface of the tobacco bin, and the piezoelectric ceramic piece is electrically connected with the power supply. The electronic cigarette has a simple atomization mode and directly atomizes the tobacco material by means of the high frequency vibration and heat of the piezoelectric ceramic.

The present invention relates to an electronic cigarette set, in particular to an ultrasonic atomizer, comprising an e-liquid guide assembly. In an embodiment, the e-liquid guide assembly comprises an e-liquid guide ceramic, e-liquid guide cotton, and springs located between the e-liquid guide ceramic and the e-liquid guide cotton and abut the e-liquid guide cotton against an atomization piece. Embodiments of the present invention use a combination of an e-liquid guide ceramic and e-liquid guide cotton to guide an e-liquid. Further details are disclosed herein.

A low-temperature smoking body and a preparation method thereof are disclosed. The low-temperature smoking body includes tobacco particles. The tobacco particle includes a particle body and a shell wrapped on the particle body. A carrier is distributed in the particle body and/or the shell. The carrier includes at least one of a raw tobacco material, a non-tobacco material, and a porous material. The carrier carries a smoking agent, and the smoking agent includes a tobacco extract and/or an atomizer. In addition, a preparation method of the low-temperature smoking body is further disclosed. The low-temperature smoking body has better smoking stability and uniformity, and the tobacco particles having core-shell structures can effectively solve the problem of liquid leakage.

Abnormally-shaped tobacco granules are provided. The tobacco granules comprise a tobacco granule body and a coating attached to the surface of the tobacco granule body. The coating contains an adhesive. The surface of the abnormally-shaped tobacco granule has one or more grooves and/or ridges, and/or, the abnormally-shaped tobacco granule has through holes therein. The surface grooves of the abnormally-shaped tobacco granules can serve as smoke channels after the tobacco granules are bonded, cured and shaped, so that the air permeability inside a total-granule tobacco product is greatly improved. The smoking resistance of cigarettes is reduced. The flammability of cigarettes is improved and the consumption of tobacco raw materials is reduced. A preparation method of the abnormally-shaped tobacco granules, a tobacco product comprising the abnormally-shaped tobacco granules, and a preparation method thereof are also provided.
