It is not identity element.
It relies primarily on to solve smoke grenade detection in conditional electronic cigarette by detecting whether cover board is closed or relies on independent biography
The drawbacks of sensor detects, and it is especially set out with a kind of smoke grenade condition detecting system and corresponding method, it is based primarily upon difference
The difference of the thermal conductivity of heat medium, is judged.
It is air around heater when smoke grenade zero load；It is tobacco leaf around heater after smoke grenade insertion；Exhaust rear heater week
Enclose is burned sheet or powder.
According to Fourier's law, the definition of thermal conductivity are as follows:
Wherein, x is direction of heat flow, qx" for heat flow density in this direction, W/m2,For temperature ladder in this direction
Degree, unit K/m.
For isotropic material, the thermal conductivity in all directions is identical.It can be counted by calculation formula
The thermal coefficient for calculating air is about 0.026W/ (mK).Since tobacco leaf moisture ratio is different, thermal coefficient is about 0.17W/
(m K)。
As depicted in figs. 1 and 2, the two thermal coefficient differs 6 times or more, theoretically there is smoke grenade and no smoke grenade, sends out
The speed difference of hot temperature variation is away from larger.The smoke grenade being pumped through after overbaking in burnt piece or powdery, it is hardly aqueous, it is thermally conductive
The gap of coefficient and new smoke grenade is larger, between air and new smoke grenade.The rate of heater temperature change be can use to sentence
It is air or new smoke grenade or old smoke grenade around disconnected heater.
According to above-mentioned principle, a kind of smoke grenade condition detecting system proposed by the present invention, as shown in figure 3, (algorithm and system one

Heat is absorbed in time is significantly higher than air), in heating engineering, the heat of calandria is absorbed in the effective air unit time
It is extremely limited, so that calandria heats up when being relatively not inserted into smoke grenade faster.
Alternatively, the slope at a time of the heating curve of heater can be calculated (according to different materials
The characteristic of matter heater can also be the slope of curve), the threshold interval of slope is concurrently set, and then whether determine Current electronic cigarette
It loads, and whether current smoke grenade used or excessively dried.
Further, it is contemplated that, aqueous unused completely new smoke grenade and (toasted, the water for using or drying for a long time
Divide residual less, and the specific heat capacity of water is maximum, causes two kinds of smoke grenade unit time absorption heats namely thermal change rate to have bright
Aobvious difference) smoke grenade, since the difference of water content is also larger (data for having 2 in aforementioned principles), it is preferred real for pretending
Mode is applied, the threshold interval of the rate temperature change further includes third threshold interval, and temperature is increased beyond 100 DEG C in 3 seconds；
When the rate of change, when being in third threshold interval, main control unit determines that current smoke grenade is to have used.
Further, in order to guarantee (to prevent from overheating and scald) using safe and user's sense organ, implement as preferred
Mode, when the main control unit determines that current heater rate temperature change is in the first threshold section and third threshold
When being worth section, i.e., it is dry use (smoke grenade out of date) that electronic cigarette, which is in unloaded or insertion smoke grenade, cuts off the power, controls
The system heater stops working.
