Booting, heating, stops heating, cleaning totally 6 instruction words at shutdown, and corresponding ID number is 1-6.Other ID numbers are defaulted as not having
Matched instruction word.
Step S300 executes the corresponding function of described instruction word.
Specifically, after control unit gets the ID number of instruction word, the function of executing corresponding ID number is begun to, for example,
If it is No. 2 ID and No. 3 ID, it will execute on/off function, and report 2s on/off music.
Step S400 detects the temperature of the heating module in real time during execution.
Specifically, the temperature for detecting heating module in real time during executing heating function, can specifically pass through detection
Module checks the current value and voltage value of heating module, and then control unit obtains fever mould according to current value and voltage value
The mode of the temperature of block obtains.
Step S500 is finished in response to reaching preset temperature or the phonetic order, and prompt is sent out for user.
If the temperature of detection has reached preset temperature or phonetic order is finished, sends out for user and carry accordingly
Show.For example, after the corresponding ID number of phonetic order is finished for 5, voice-output unit reports " thanks use ".ID number is
After 6 are finished, voice-output unit loop play 2s cleans music.When electronic heating apparatus is under heated condition,
Before heating temperature reaches preset temperature, user can be reminded by way of triggering the vibration of vibration prompt unit, work as arrival
When preset temperature, user can be reminded by triggering light prompt unit and vibration prompt unit simultaneously.
In one embodiment, a kind of heating means of electronic heating apparatus can also include：
The validity of described instruction word is analyzed.
Control unit reads the phonetic order of voice-input unit pickup, as read the corresponding instruction word of phonetic order
ID number ranging from 1-6 then shows have matched voice to input, i.e., has the sound of instruction word to enter in the effective range of microphone
Voice-input unit, at this moment control module will be to instruction word ID number progress validity parsing.It is other information such as to read ID number,
It is then invalid voice input information, need not be handled.Validity parsing is carried out according to ID number, prevents some unreasonable
Voice request.In the power-offstate, the power-on instruction word that only ID number is 2 is considered valid, while can execute power up function,
Other ID numbers are then ignored.Under open state, the effective instruction that can be responded is No. 1 ID cloud and mist, and No. 3 ID shut down, and No. 4 ID add
Heat, No. 6 ID cleanings, and these ID numbers can only respond one of them, other ID numbers will be ignored, until the ID number responded
After the completion of function executes, new voice input could be received.No. 5 ID stop heating only after No. 4 ID heating are opened to holding
Before row is completed, as effective instruction.
Execute the corresponding function of effective instruction word.
Specifically, if No. 2 ID and No. 3 ID will effectively execute on/off function, while 2s on/off sounds being reported
It is happy.No. 2 ID can also unlock electronic cigarette, allow performing effectively for other ID numbers.No. 3 ID can also will be on electronic heating apparatus
Lock, only carries out the function of No. 2 ID.If No. 1 ID will effectively execute the function of wake-up and be output by voice unit report " you are good
I is cloud and mist ".No. 4 ID will effectively execute heating function, while voice-output unit reports voice " Smoking is harmful to your health ", electricity
Adjustment module is pressed to start to work, reminding module carries out real-time prompting to heated condition.No. 4 ID allow No. 5 while executing function
ID is effective.As during heating, voice-input unit is picked up to the voice command input for having the corresponding instruction words of No. 5 ID, it will
Terminate the function of No. 4 ID.No. 5 ID are effectively or heating terminates can all trigger voice-output unit report " thanks use ".No. 6 ID
It will effectively trigger and execute the cleaning function music of voice-output unit loop play 2s cleanings simultaneously, while start cleaning function,
By the carbon cleaning on heating conductor, plays after cleaning function and also terminate.
Above-described embodiment is picked up by the phonetic order to user, then obtains the corresponding instruction word of phonetic order,
The validity for instructing word is analyzed again, realizes the voice control of electronic heating apparatus, while avoiding electronics heating dress
It sets the voice erroneous judgement that may cause due to the addition of voice module, execute instruction the problems such as word corresponding capability error, and have
Overcoming to effect under existing electronic cigarette button is used for a long time can not bounce after insensitive, screens, be easy the problems such as exception-triggered.Into
One step, by detecting the temperature of heating module in real time while executing phonetic order, realize heating module heating temperature
Closed loop adjust, may make the heating temperature of heating module to keep stablizing, and be effectively controlled the calorific value of heating module,
To bring better smoking experience sense to user.Further, by being finished in phonetic order or reaching default warm
Prompt is sent out for user when spending, can both protect electronic heating apparatus, or user provides more preferable suitable smoking mouthfeel.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
