Specific embodiment
A kind of electronic cigarette calandria with tubular structure of the invention is described with reference to the drawings.
The present embodiment is a kind of electronic cigarette heating element using thick-film resistor power-up fever, as depicted in figs. 1 and 2 by sending out
Hot body 6 is mounted on pedestal 1 and is formed, in use, heater 6 will be inserted into cigarette, in cigarettes between pipe tobacco is heated,
Heater 6 is the key that the present embodiment, and heater 6 as shown in Figure 1 includes metal sheet substrate 5, is wrapped in metal sheet substrate 5
Insulating medium layer 2, the thick-film resistor 3 with setting resistance being printed on dielectric 2, the both ends of thick-film resistor 3 are directly adopted
It is connected with conducting wire with battery, or is electrically connected with the electrode 4 being arranged in pedestal 1, electrode is connected with battery.In the present embodiment,
Thick-film resistor 3 can be set on the surface or two-sided surface of 2 single side of insulating medium layer, be set as needed.Metal chip base
Body 5 still maintains certain toughness, good thermal conductivity and workability, the specific trade mark under mechanical strength with higher
Sheet metal can fire insulating medium layer 2 in specific technique lower surface, such as glass glaze.
Insulating medium layer 2 is fired on the surface layer of metal sheet substrate 5, and insulating medium layer 2 has higher insulating properties, insulate simultaneously
The coefficient of expansion of 2 material of dielectric layer is close to the coefficient of expansion of metal sheet substrate 5 and the coefficient of expansion of the two matches, and guarantees in heat
Swollen contraction does not crack;Thick-film resistor 3 is printed on insulating medium layer 2, forms resistance circuit, by thick film electricity after energization
Resistance 3 converts electrical current into thermal energy;The effect of electrode 4 is to connect with battery, is conductive, and electric current can be transmitted to thick-film resistor 3.
Embodiment 2 and embodiment 3 are as shown in Figure 3 and Figure 4, with the label that two pieces of heaters are as shown in Figure 3 in embodiment 2
7 and label 8 shown in (the first heater 7 and the second heater 8), it is exactly the heater 6 in a kind of fever tablet, with embodiment 1
It is consistent, only shape as needed is varied.It is the structure chart of embodiment 3 as shown in Figure 4, which uses three
Piece heater 9,10,11 (third heater 9, the 4th heater 10 and the 5th heater 11), in the actual process as needed
There can be multiple heaters, be thus inserted into cigarette, dispersed-heated can make to heat more uniform.With existing technical solution
It compares, the structure and technique that the present embodiment is related to can be such that the service performance of electronic cigarette is well improved, and fever tablet belongs to entirely
The core of smoking set is eliminated once damaging entire smoking set, and the present embodiment can significantly prevent this fracture
Risk, the service life for greatly extending entire smoking set greatly reduce the brittle failure risk of use process, improve service life,
Simultaneously monolithic volume be made smaller, realize biplate and multi-disc heating sheet insertion cigarette heating, cigarette tobacco flue-curing more evenly, mouth
Sense gets a promotion, and increases user experience.In embodiment 3, for three heaters 9,10,11, two in embodiment 2 are generated heat
Body 7,8, connects and can be series winding or parallel connection in electric mode, after two heaters 7,8 are connected in series in embodiment 2, then accesses
Battery, it is of course also possible in parallel as needed access battery later, in this way, power switch can be respectively set, in practice, two
A heater can use different power, and one powerful, smaller power, be inserted into cigarette when by heater
When start smoke when, can two heaters be all powered on, scheduled temperature will be quickly reached in this way, smoke, when reach temperature
Degree can close a heater later, leave behind powerful fever body running, after can be transformed to only small function for a moment
The fever body running of rate, in short, can be set as needed switch.For embodiment 3, the connection types of three heaters can be with
Very flexibly, can with three series windings or three parallel connections, can also after two series windings again it is in parallel another, equally can also two
A another heater in parallel of contacting again later, connection type is very flexible in a word, and consumer can think according to oneself
Method flexible choice is selected with multiple switch by consumer oneself in practice, enhances user experience.
Embodiment 2 and embodiment 3 aiming at the problem that cigarette heat is unevenly distributed, the technical solution adopted is that, using biplate
And multi-sheet structure, the distance of reduction cigarette outer layer tobacco to fever tablet, to reduce temperature difference.Thick film circuit formula fever tablet is with gold
Belonging to is matrix in the case where ensure that intensity and toughness, and thickness can accomplish the 1/2 even more thin of ceramic chip fever body thickness,
Therefore, structure, which has been made into biplate and multi-disc still, can guarantee the inside for being freely insertable into cigarette.
