As shown in Figure 3, Digital Logical Circuits 43 also comprises self adaptation sensitivity generation circuit 436, self adaptation sensitivity generation circuit 436 is connected with digit counter 431, digital comparator 432, is used for receiving the output data of digit counter 431, and to digital comparator 432 input data.
When not having the smoking action, the frequency of the oscillating clock signal that relaxation oscillator 41 produces is constant, thereby, the count value that is used for digit counter 431 generations of this oscillating clock signal of reception can not become yet, described count value is output to the self adaptation sensitivity generation circuit 436 that is preset with numerical value of N x, and self adaptation sensitivity generation circuit 436 exports the difference of count value and numerical value of N x to digital comparator 432 as the smoking threshold value.Therein among embodiment, every through after the certain time interval when not having the smoking action, self adaptation sensitivity generation circuit 436 repeats said process, export the difference of current count value and numerical value of N x to digital comparator 432 as new smoking threshold value, so repeatedly, can guarantee that the smoking threshold value in the digital comparator 432 is the value that adapts to current environment most.In another embodiment, can the replacement switch be set at the electronics cigarette, the user can be by the replacement switch smoking threshold value of initiatively resetting.
When the electronics cigarette is in the transportation, the capacitive window of condenser type miaow head 30 will shake centered by its resting position back and forth, cause described miaow head capacitance will the time little when big, but the average capacitance value is constant, therefore, in described reference time length T, the count value that digit counter 431 produces is constant, accordingly, described smoking threshold value is also constant.
Among embodiment, the value of numerical value of N x should make condenser type miaow head 30 heating wire drive circuit 50 when being subjected to 300 Pascals' negative pressure open therein.
By self adaptation sensitivity generation circuit 436 is set, further improved sensitivity and the reliability of electronics cigarette, significantly improved the yield of electronics smoke product.
