Abstract
The present invention proposes a kind of electronic smoke atomizer, including the shoe cream room for storing tobacco tar and for drawing tobacco tar from shoe cream room and carrying out the atomizing component of heating atomization；Atomizing component includes the porous body for drawing and conducting tobacco tar；Filled with the three-dimensional fever network that can form continuous conduction path in porous body, the tobacco tar for drawing and conducting to porous body carries out heating atomization；The electrode connecting portion being electrically connected with three-dimensional fever network is additionally provided on porous body.The atomizing component of atomizer of the invention, it is basic using porous body as skeleton, conductive three-dimensional fever network doping is filled in porous body and forms one, entire atomizing component 3 D stereo is set to generate heat, the tobacco tar atomization space that hole interior suction is taken and conducted is bigger, more efficient, the heated volatilization of tobacco tar ingredient and escape more uniform and quick, mouthfeel reduction degree is higher；And in atomization process, aerosol can be escaped from each surface of porous body, it is easier to smoke.
Description
Technical field
The present embodiments relate to electronic cigarette field more particularly to a kind of electronic smoke atomizer, electronic cigarette, atomizing component and
Preparation method.
Background technique
The core component of electronics smoke product is that the atomizer for generating tobacco tar aerosol is evaporated to electronics tobacco tar, atomizer
Function realization be mainly based upon atomizing component；Atomizing component have one for draw and conduct tobacco tar porous body and
One tobacco tar for being set on porous body for drawing and conducting to porous body carries out the heater element of heating atomization.Wherein, porous
Body is the component that a therein has capillary micropore, and the infiltration that tobacco tar can be carried out by internal micropore is absorbed and passed
It leads；And heater element has heating part and conductive pin part for fever, what heating part was used to carry out porous body conduction
Tobacco tar carries out heating evaporation, forms the tobacco tar aerosol for Gong sucking.
Usually atomizing component uses porous ceramics thick film heating body at present, is micro- to draw with tobacco tar and conduct micron order
The porous ceramic bodies in hole are carrier, and heater element is made in sintering after printing fever route by silk-screen printing technique.And porous pottery
Porcelain body generallys use the mode re-sintered after ceramic material is mixed with pore creating material and is prepared, and has in sintered ceramic body a large amount of
Micropore, for tobacco tar is drawn and is conducted；Automated production may be implemented in whole preparation process, and technology stability is higher.
Above atomizing component is in preparation, since there are micropores for ceramic body, so that porous ceramic bodies surface is relatively thick
It is rough, cause the heater element adhesive force prepared in porous ceramic bodies surface printing heating circuit and follow-up sintering poor, and exist
It is just uneven and the case where permeated into micropore, so that the resistance stability and lack of uniformity of heater element, when use
It will appear resistance floating shakiness, the problem that even fracture can not be conductive；Simultaneously due to thermal cycle impact effect after continuing working,
Heater element is easily caused to peel off.
Summary of the invention
In order to solve on electronic cigarette porous ceramic bodies in the prior art resistance value consistency that printing fever route generates and
Associativity deficiency problem, the embodiment of the present invention provides a kind of resistance value and smoke all has the electronic smoke atomizer of higher stability.
A kind of electronic smoke atomizer of the invention, including the shoe cream room for storing tobacco tar and for being inhaled from shoe cream room
It takes tobacco tar and carries out the atomizing component of heating atomization；The atomizing component includes the porous body for drawing and conducting tobacco tar；Institute
State the tobacco tar filled with the three-dimensional fever network that can form continuous conduction path in porous body, for drawing and conducting to porous body
Carry out heating atomization；The electrode connecting portion being electrically connected with three-dimensional fever network is additionally provided on the porous body.
Preferably, non-conductive ceramic material system when the porous body is using below atomizing component maximum operating temperature
It is standby.
Preferably, conductive ceramic material when the three-dimensional fever network is using below atomizing component maximum operating temperature
Preparation.
Preferably, the ceramic material of the conduction includes at least one of titanium nitride, titanium carbide or titanium silicon carbide ceramics.
Preferably, the resistivity of the atomizing component is 0.5~2.5m Ω cm.
Preferably, the volume of the non-aperture sections of the porous body and the volume ratio of three-dimensional fever network are 0.5~3:1.
The atomization group that the present invention further also proposes a kind of preparation method of atomizing component and prepared by this method
Part, wherein preparation method includes the following steps:
