Chamber.FPC flexible circuit board 420 is wrapped in the outer wall of heat conducting pipe 410 with high temperature gummed tape, and FPC flexible circuit board 420 is electrically connected to mist
Change the main circuit board 150 of device.Overclad tubes 430 are nested in the outside of heat conducting pipe 410 and FPC flexible circuit board 420, overclad tubes 430
Thermal insulation layer 425 is equipped between FPC flexible circuit board 420, thermal insulation layer 425 is aerogel layer.Air inlet pipe 440 and heat conducting pipe 410
Lower end is tightly connected, and air inlet pipe 440 is connected to heat conducting pipe 410.
Heating structure 400 further includes temperature measuring equipment 450, and temperature measuring equipment 450 is installed close to FPC flexible circuit board 420, thermometric
Device 450 is electrically connected to the main circuit board 150 of atomizer.Temperature measuring equipment 450 is able to detect the temperature of FPC flexible circuit board 420
And main circuit board is fed back to, convenient for control temperature.In the present embodiment, temperature measuring equipment 450 is negative warm nature thermistor, has splendid
Precision.In other embodiments, other common temperature elements can also be used and substituted.
The top and bottom of overclad tubes 430 are fixed on atomizer enclosure interior with peek high temperature resistant plastic cement 470 respectively.
With reference to Fig. 4-Fig. 5, second aspect of the present invention provides a kind of atomizer, in addition to including above-mentioned heating structure 400, atomization
Device further includes shell 100, battery 130, main circuit board 150, and heating structure 400, main circuit board 150 and battery 130 are set to shell
In body 100, battery 130 is electrically connected to main circuit board 150.
With reference to Fig. 6-Fig. 9, atomizer further includes upper cover 120, and upper cover 120 is equipped with sliding closure structure 200, and sliding closure structure 200 wraps
Slip lid 210 is included, slip lid 210 includes the connection for being set to the cover board 212 of the upper surface of upper cover 120 and being fixedly connected with cover board 212
Portion 214, the through-hole 122 that interconnecting piece 214 passes through the upper surface of upper cover 120 extend into shell 100, the side surface tool of upper cover 120
There is sliding rail 124, sliding closure structure 200 further includes sliding axle 220, and sliding axle 220 is connected to the interconnecting piece 214 of slip lid 210 and can edge
Sliding rail 124 slides, and the length of the through-hole of the upper surface of the length and upper cover 120 of sliding rail 124 is adapted, and the size of cover board 212 is big
In the through-hole 122 of upper cap upper surface, through-hole 122 is enable to be completely covered, cover board 212 is higher than the upper surface of upper cover 120
0.5mm-1mm or so, so that the upper surface of cover board 212 and upper cover 120 not CONTACT WITH FRICTION.
The cover board 212 and interconnecting piece 214 of slip lid 210 are integrally formed.In the present embodiment, two sliding axles 220 run through slip lid
Interconnecting piece 214, two ends of sliding axle 220 lie across in the two lateral walls of upper cover 120, and two ends of sliding axle 220 accommodate
In in sliding rail 124.Sliding axle 220 is stainless steel shaft.In the present embodiment, shell 100 and upper cover 120 all have straight and parallel
Two sidewalls, convenient for straight sliding rail 124 is arranged.
It should be understood that the present embodiment is only to provide a kind of scheme preferred, convenient for assembly, in other embodiments
In, sliding axle can not be through slip lid, cunning can be respectively set in the interconnecting piece two sides of slip lid position corresponding with sliding rail
Moving axis can also realize the purpose of this patent.And the sliding rail of the present embodiment is through-hole, in other embodiments, sliding rail can also be groove,
As long as sliding the tip of the axis can be accommodated.
In the present embodiment, sliding axle 220 is through the two side walls of upper cover 120 and the interconnecting piece 214 of slip lid, because on
The side wall of lid 120 is insertion shell 100, therefore the sliding axle 220 for passing through sliding rail 124 can be limited by the inner wall of shell 100
Action, does not fall out sliding axle 220.
In other embodiments, the quantity of sliding axle can also be 3 or more.
The through-hole 122 of 120 upper surface of upper cover is connected to the heating chamber 300 (i.e. inside heat conducting pipe 410) of atomizer.It pushes and slides
When lid 210 opens through-hole 122, it can be inserted into heating substance to heating chamber 300 and heated, heating substance is extracted after the completion of heating,
Slip lid 210 can be pushed to be closed through-hole 122.
Upper cover 230 is provided with torsion spring mechanism 240 close to the position of 214 lower surface of interconnecting piece, is used to form and closes lid and uncap
Inflection point between two positions.Torsion spring mechanism 240 includes torsional spring 242, and the straight stretching in two free ends up and down of torsional spring 242 is formed
One acute angle, the protrusion 215 of the first free end end mounting 214 lower surface of interconnecting piece of torsional spring 242, the second free end end is hung
The protrusion 125 of the lower surface of lid 120 is connected, torsional spring 242 forms pressured state after both ends mount, when slip lid 210 slides into Jie
When closing the middle position of lid and uncapped position, torsional spring 242 is pressurized maximum.Full open end and fully closed lid two are slided into slip lid 210
When a extreme position, the compression of torsional spring 242 is minimum, so that slip lid 210 tends to walk to two extreme positions, it can be real
Now uncap and close the in stable condition purpose of two extreme positions of lid.
But it cannot be understood as limitations on the scope of the patent of the present invention.It should be pointed out that for this field
For those of ordinary skill, without departing from the inventive concept of the premise, various modifications and improvements can be made, such as to each
Different characteristic in embodiment is combined, and these are all within the scope of protection of the present invention.
